This paper describes a technique to reduce insignificant Key Performance Indicator (KPI) data generated by Network Elements (NE) like Radio Access Network (RAN) and Core Network (CN) or Element Management System (EMS) or Network Management System (NMS). The aim of this technique is to utilize network bandwidth (i.e. control plane traffic load) and storage space in EMS or Operation Support System (OSS) efficiently. Realizing this aim, helps operators of EMS/OSS identify network KPI deterioration in near real time. Using this technique also reduces loss of critical events in lieu of network bandwidth loaded with heavy KPI data. Control plane systems in 4G as well as 5G network can both use this general technique. The disclosed technique utilizes a parameter called as KPI delta, defined for each KPI to determine significance of a KPI data. Further, this technique proposes systems, on how to use KPI delta to reduce the KPI data. Then various methods to derive or calculate KPI delta are described, namely unsupervised learning (K- means clustering) method, statistical analysis (Douglas Peucker algorithm) method and a rudimentary method (keeping KPI delta as zero). Performance evaluation of these three methods shows that unsupervised learning (K-means clustering) gives better results compared to other two methods for KPI data files: size improvement by 0.81% and 3.81%; data point improvement by 3.02% and 14.62%.

Nowadays there is an increasing need for a general paradigm which can simplify network management and further enable network innovations. Software Defined Networking (SDN) is an efficient way to make the network programmable and reduce management complexity, however existing SDN solutions do not realize the full potential of SDN because of their lack of scoping in network management. In response to limitations of current Software Defined Networking (SDN) management solutions, we propose a recursive approach to enterprise network management, where network management is done through managing various Virtual Transport Networks (VTNs) over different scopes (i.e., regions of operation). Our approach offers a generalized and structured framework to realize the full potential of SDN using recursive scoped management, and our VTN-based approach provides communication service with explicit Quality-of-Service (QoS) support for applications via transport flows. Each VTN involves all mechanisms (e.g., addressing, routing, error and flow control, resource allocation) needed to support such transport flows. Based on this approach, we design and implement a management architecture, which recurses the same VTN-based management mechanism for enterprise network management. Our experimental results show that our management architecture achieves better performance demonstrated through unicast and multicast video applications.

Service overlay networks and network virtualization enable multiple overlay/virtual networks to run over a common physical network infrastructure. They are widely used to overcome deficiencies of the Internet (e.g., resiliency, security and QoS guarantees). However, most overlay/virtual networks are used for routing/tunneling purposes, and not for providing scoped transport flows (involving all mechanisms such as error and flow control, resource allocation, etc.), which can allow better network resource allocation and utilization. Most importantly, the design of overlay/virtual networks is mostly single-layered, and lacks dynamic scope management, which is important for application and network management. In response to these limitations, we propose a multi-layer approach to virtual transport network (VTN) design. This design is a key part of VTN-based network management, where network management is done via managing various VTNs over different scopes (i.e., ranges of operation). We explain the details of the multi-layer VTN design problem as well as our design algorithms, and focus on leveraging the VTN structure to partition the network into smaller scopes for better network performance. Our simulation and experimental results show that our multi-layer approach to VTN design can achieve better performance compared to the traditional single-layer design used for overlay/virtual networks.

The residential gateway is a key device in the provision of Internet access to a household or to a small office. Managing a residential network nowadays means configuring the functionality provided by the residential gateway, which is often a task that requires a certain level of technical expertise that most residential users lack. Internet Service Providers sometimes address this usability problem by managing the residential gateway from a central location and offering a way of configuring simple functions such as the password of the Wi-Fi network through a web-based application. In this paper a new user-centric management architecture is proposed, to increase the active engagement of residential users in the management tasks of their own networks, improving the usability of the network and facilitating the provision of new services. In this approach, residential network management applications are split in two components: a front-end handling user interaction and running on the user's preferred device (PC, laptop, smartphone); and a back-end built on top of both the Software Defined Networking (SDN) and the Network Functions Virtualization (NFV) paradigms. The solution takes advantage of the fine-grained control of network traffic and the convenience to communicate network events provided by SDN and the outsourcing of traditional network functions like routing or NAT from the residential gateway to a cloud-based infrastructure managed by the Internet Service Provider. In this paper the advantages and challenges of this approach are discussed, based on the results obtained from a proof of concept system that has been developed to evaluate the feasibility and performance of the proposal. The residential network usability is improved by implementing a new user-centric management model.Residential network management applications (RENEMA apps) involve users in managing their own networks.Residential network services (RENESEs) expedite and simplify the development of RENEMA apps.The virtualized management and networking domain (vMANDO) concept hosts the SDN and NFV components.The architecture allows avoiding the manufacturer lock-in effect.

Since today's networks use traditional centralized management systems, the management became costly with the growth in the number of network equipments and available services. It became then clear that it was necessary to distribute the central management responsibilities throughout the network equipments. This article proposes an autonomic decision system with learning capabilities based on Artificial Intelligence concepts, to be used by network equipments in mesh-network environments without the need of a central knowledge. Considering a specific case of QoS routing, this system is able to establish bandwidth-aware communication paths between pairs of nodes in a distributed approach, without the complete knowledge of the network and the available bandwidth of its links. To develop this system in a real network an architecture has been specified and built, denote as DistArch. This architecture provides all the functionalities to perform distributed autonomic decisions in large-scale networks. The results of this approach show that, by cooperating with neighbour network agents, even without a full knowledge of the network state, it is possible to establish bandwidth-aware communication paths as optimal as the ones obtained with a central decision approach that contains full network information, being able to react to network changes with a fast convergence.

Enforced from February 18th, 2013, the network separation system has been promoted as a solution to block the leak of important information in public institution or in private, which has been increased continuously. Under pretext of continuity, the entire finance system has operated the integrated network of intranet and Internet before the network separation system. Such operational environment led more internal and external threats due to development of APT or malwares and carelessness of insider, and the government has prepared the high level security solution called the network separation. Through the network separation, based on the guideline of financial authority, the intranet and the Internet have been separated to protect the corporate and private information from the malware infection or hacking through the external Internet. In this thesis, through the concept of network separation and the case of establishment of network separation in the financial field, the structure is to be evaluated, and through the safety of system, efficiency of management, and safety operation solution of data system, the optimized network separation system in the financial field is to be designed. Furthermore, the network separation system is categorized into the establishment of network separation solution, establishment of network connection solution, establishment of network, and establishment of infrastructure for information protection to be evaluated. Therefore, the system establishment and connection through detailed analysis of regulation are required, and the assurance of security and performance and safety of the network separation system through the integration of conventional security system and new establishment and process are studied.

Policy-Based Network Management (PBNM) is one of the approaches used by network administration groups for Quality of Service (QoS) and administration on the internet. This paper seeks to propose the adoption of a Policy Creation Model for Policymaking in some organizations. The model will then be applied to a real scenario Botswana International University of Science and Technology (BIUST) network. A combination of technical computer skills, effective network monitoring and a workable policy helps in attaining effective bandwidth management by the users. This study extends one of our researches in network traffic monitoring in BIUST network.

Nowadays, with the growth of heterogeneity of network equipment and software, and involved a variety of advanced network technology, the complexity of computer network have rapidly increased. Especially demands for high-performance network service in advanced data-intensive scientific research are dramatically increased. In order to cope with the network performance issue, this paper proposes the end-to-end (ETE) network performance management framework based on case-based reasoning with the case library and multi-agent integrated with perfSONAR as well as large-scale network flow monitoring. It provides a sophisticated framework for both network operator and user to systemically identify ETE network performance issues that are detected, diagnosed and recovered. The real cases are modeled and implemented into the casebase in the real experimental environment, a national research network of Korea. To verify the proposed framework, validation of the cases in the casebase is demonstrated.

The intrusion detection systems, firewalls and other security devices provide a guarantee for the safe operation of the network, but with the wide application of network, virus, hackers and other security incidents are increasing, these security devices will send tens of thousands of a warning in a very short period of time, the network management personnel is difficult to find useful information from these massive alarms. In addition, with the increasingly large scale network, mobile network, data management, data related to SMS, MMS message service system, single security device cannot detect all intrusions, so we must consider how to make these equipments work harmoniously. In this paper, based on the above problems, the mobile data network security integrated management system is studied, and the research and implementation of security event management mechanism is discussed in detail. The event management proposed in this paper can be regarded as an extension of the concept of network management, which enriches the content of the five functions of network management. In addition, the traditional network management and system management are two independent concepts. The two management systems can be combined together through the event management, so that the network security operation can be further improved. The purpose of security event modeling is to format the events from different event sources to facilitate subsequent processing. In this paper, the object oriented modeling method is adopted, which is scalable, and at the same time, the difference of all kinds of events is fully considered. For the description of the model, this paper uses the XML language, which is universal. Harm of computer virus on the network security management is more and more big, the characteristics of computer virus and the typical symptoms and its harmfulness are analyzed, and the security of mobile communication network is analyzed. The proposed system modification virus prevention. Implementation of general security management system in mobile data network is the focus of this article, mainly from the three aspects of the audit log management, security event monitor and account password management in the mobile data network involving multiple business systems in the implementation of integrated security management system. In this paper, we adopt rule based hierarchical system architecture, the coupling degree of each module is relatively loose, and it has great flexibility in the deployment.

Given the widespread deployment of proprietary network functions (NFs), many network management functions (such as testing and policy compliance) need accurate NF models to ensure correctness and reliability. However, because of their proprietary and complex nature, these NFs lack a standardized behavior model. This article reviews existing NF models and modeling approaches, proposes generic modeling methodologies to create standard NF models, and presents the model's applications in network management tasks.

This paper presents a real-time traffic network state estimation and prediction system with built-in decision support capabilities for traffic network management. The system provides traffic network managers with the capabilities to estimate the current network conditions, predict congestion dynamics, and generate efficient traffic management schemes for recurrent and non-recurrent congestion situations. The system adopts a closed-loop rolling horizon framework in which network state estimation and prediction modules are integrated with a traffic network manager module to generate efficient proactive traffic management schemes. The traffic network manger adopts a meta-heuristic search mechanism to construct the schemes by integrating a wide variety of control strategies. The system is applied in the context of Integrated Corridor Management (ICM), which is envisioned to provide a system approach for managing congested urban corridors. A simulation-based case study is presented for the US-75 corridor in Dallas, Texas. The results show the ability of the system to improve the overall network performance during hypothetical incident scenarios.

© 2018 IEEE. In today's optical networks, Light paths are established through Network Management System and Element Management System, which is a manual and cumbersome process. Paths are computed and pre-setup according to the known traffic d emands, a nd p rovisioning a ny new service takes time. Several efforts have recently been made to make the path establishment process dynamic, including the Software Defined N etworking a pproach. H owever all of this work has assumed fully interconnected fabrics of the network devices which is generally not the case. The task of end to end path establishment between network elements and through fabric are interrelated, and this task remains incomplete, without consideration of the switch's limitations. This work highlights for the first time the issue of path establishment dynamically through a switch fabric. The paper briefly e xplains t he p roblem a nd s uggests an SDN based solution using the OpenFlow protocol. This work contributes a represention of the basic framework which will be required to make the complete path setup process dynamic. The paper also includes an operational description.

Optical network management and solution system provides services for a complete end-to-end provisioning on the transport network. In Optical networks, various technologies like SDH, PTN, EoSDH and WDM are integrated with each other and also it implemented with their own required network elements. This complex hierarchy and the large value of network data are in each and every individual EMS (Element Management System). While these various EMS data are collected through the north bound interface in primary Network Management and Solution System, it should be large scale data with multiple varieties of data set. Traditional data processing tools like MySQL cannot reach the requirement up to this level. This paper approaches the network big data handling with Hadoop distributed file system to overcome that incompetence. Using Hadoop advantages like automatic cluster distribution of data handling, parallel processing and open source with integration of multiple platforms, this is used for the network discovery, network alarm extraction and integrating with network application platforms. This paper discuss the performances of the traditional MySQL DBMS and Hadoop based data processing frameworks for Optical network management systems. Various sizes of optical network data in terms of links processed and results are discussed. Hadoop with Spark engine provides good efficiency compared to others for the optical network management system while it increases in size is observed.

Nowadays, the prevailing use of networks based on traditional centralized management systems reflects on a fast increase of the management costs. The growth in the number of network equipments and services reinforces the need to distribute the management responsibilities throughout the network devices. In this approach, each device executes common network management functionalities, being part of the overall network management platform. In this paper, we present a Unified Distributed Network Management (UDNM) framework that provides a unified (wired and wireless) management network solution, where further different network services can take part of this infrastructure, e.g., flow monitoring, accurate routing decisions, distributed policies dissemination, etc. This framework is divided in two main components: (A) Situation awareness, which sets up initial information through bootstrapping, discovery, fault-management process and exchange of management information; (B) Autonomic Decision System (ADS) that performs distributed decisions in the network with incomplete information. We deploy the UDNM framework in a testbed which involves two cities ($$\approx$$ź250 km between), different standards (IEEE 802.3, IEEE 802.11 and IEEE 802.16e) and network technologies, such as, wired virtual grid, wireless ad-hoc gateways, ad-hoc mobile access devices. The UDNM framework integrates management functionalities into the managed devices, proving to be a lightweight and easy-respond framework. The performance analysis shows that the UDNM framework is feasible to unify devices management functionalities and to take accurate decisions on top of a real network.

Updating a network is an essential and continual task in the management of today’s softwarized networks. When applying updates on distributed network elements, desired network properties, such as drop- and loop-freeness, might be transiently violated. Although being crucial, update consistency has yet been less considered in network management. In this paper, we argue for incorporating the particularities of update consistency into the reconfiguration process of continuous network management. We present a generic management architecture allowing for an appropriate selection of an update mechanism and its parameters based on expected inconsistency effects. We investigate update consistency for the case of multicast routing and show in an extensive analysis why simultaneous drop- and duplicate-freeness is not possible. We present an update procedure for multicast routing updates that identifies critical update steps, which are fed back into the reconfiguration process, along with a lightweight approach that allows for the selection of an update strategy, preventing either drops or duplicates. Furthermore, we present an optimization of an existing powerful, but resource-intensive update approach as well as an approach for in-network filtering of duplicates.

It is a consensus that the Internet suffers from architectural limitations, including resilience, scalability, and manageability, among others. Therefore, companies access the Internet by establishing a service level agreement (SLA) in the attempt to ensure quality of service (QoS) for users. To address the current limitations of the Internet, researchers have recently proposed the edge as a service (EaaS) paradigm as a suitable solution to improve the access capacity of edge networks. EaaS uses network virtualization and software-defined networks to expand flexibility and manageability of access to edge network resources. Moreover, to maintain QoS assurance for users, EaaS addresses network events (such as traffic overload, failures, etc.) that can potentially affect QoS. Within this context, this paper proposes a software-defined management of EaaS environment, called SDM-EaaS. The proposal enhances the QoS for the end user, while improving the utilization of network resources in dynamic scenarios allowing for unpredictable changes in traffic demands, network infrastructure availability, and customer characteristics. Experiments based on emulation as well as real testbed demonstrate the effectiveness of the SDM-EaaS strategy.

Choice-based network revenue management concentrates on importing choice models within the traditional revenue management system. Multinomial logit is a popular and well-known model which is base choice model in the revenue management. Empirical results indicate inadequacy of this model for predicting itinerary shares and more realistic models such as nested logit can be proposed for substituting it. Incorporating complex choice models in the optimization module based on statistical tests without considering the complexity of the obtained mathematical model, would lead to increase the complexity of a system without obtaining significant improvement. According to influencing the discrete choice model on the structure of optimization model, it is necessary to analyze the interaction between specific discrete choice and optimization models.In this paper, a knowledge acquisition subsystem is introduced for providing intelligence and considering the most suitable choice models. We develop the feedforward multilayer perceptron artificial neural network for forecasting revenue improvement percent obtained by using more realistic choice models. The obtained results demonstrate new system will decrease the complexity of the system simultaneously with preserving the firm’s revenue. According to the computational results, by increasing the resource restriction, the process of incorporating more realistic choice model will be more important.

In cellular networks, as a result of the heterogeneous network layout, a number of community, in the entire network, micro base station district energy management issues that need to be unified management and scheduling, and combined with the flow of communication and transport business and the efficiency of energy management, the development of energy management system based on cloud computing platform, according to the system, can have better energy efficiency, realize the communication and the advantage of energy balance. This article mainly from the two aspects of theory and actual implementation of this management system research.

Network Functions Virtualization (NFV ) is an attempt to help operators more effectively manage their networks by implementing traditional network functions embedded in specialized hardware platforms in term of virtualized software instances. But, existing novel network appliances designed for NFV infrastructure are always architected on a general-purpose x86 server, which makes the performance of network functions limited by the hosted single server. To address this challenge, we propose ApplianceBricks, a novel NFV-enable network appliance architecture that is used to explore the way of consolidating multiple physical network functions into a clustered network appliance, which is able to improve the processing capability of NFV-enabled network appliances.

In network management, significant research efforts have been carried out to automate and facilitate the tasks conducted by network administrators. However, so far, none of these efforts has exploited the opportunities of jointly using the Situation Management discipline and the mashup technology for network management. This paper introduces an approach, called Rich Dynamic Mashments, to facilitate the daily work of network administrators when dealing with unexpected, dynamic, and heterogeneous situations. We have referred to as nmsits to such type of network management situations (e.g., a sudden packet loss in a core router of a network backbone and an unforeseen slowness in data transmission over a link between virtual routers) and mashments to tunable mashups that use Situation Management for conducting network management tasks. The proposed approach is made up by the models of nmsits and mashments, the mechanisms to automatically recognize nmsits and dynamically compose mashments, and the architecture supporting these models and mechanisms. We further implement a prototype of our approach and conduct an extensive analysis on networks based on the Software-Defined Networking paradigm. The analysis results have provided directions and evidence that corroborate the feasibility of using Rich Dynamic Mashments as an effective approach for network management in terms of time-recognition, time-composition, time-consuming, time-response, and network traffic.

Centre for Development of Telematics (C-DOT) was doing a project of migrating Public Switched Telephone Network (PSTN) to Internet Protocol (IP) based Network. The new upgraded network was consisting of IP Phones, Digital subscriber line access multiplexers (DSLAMs), Aggregators, Routers, Soft Switch and Element Management System (EMS). The existing copper lines were reused between DSLAMs and IP Phones as Asymmetric digital subscriber lines (ADSLs). The copper lines were old and fluctuating randomly. The optical fibers connecting routers, aggregators and DSLAMs were regularly cut in between due to digging process by different agencies. This resulted in multiple joins in the fiber and introduced random fluctuation in links. The frequency of the fluctuation was not high enough to be detected at network element itself. This introduced unpredictable and heavy trap load affecting the network services and EMS. Reaching sites personally to check the links was not feasible or extremely difficult. We developed and implemented a solution based on leaky bucket algorithm which helped us to isolate such links remotely and prevented EMS from overload. There was 90.33% reduction in event generation rate and 23% reduction in total DB storage. The fluctuating links were isolated with almost 100% accuracy.

With the broad adoption of service-orientation for the realization of business applications and their provisioning and usage over cloud infrastructures, the topology of the resulting service networks is becoming extremely complex. Due to the composition of services for value-added business capabilities and the reusability of a service in multiple compositions, the execution of one service often depends on other services and changes in its provisioning can affect the health of large parts of the service network. The lack of insight on the relationships between the network components makes the management of the service network's health hard and error prone tasks. This article introduces a service network modeling approach for capturing the topology of a service network at design time. The approach considers the complete modeling process from representation, through collection, to analysis of the relationship information. The major contributions are a generic and adaptable modeling structure, a classification of service network entities and relationships, and a modular management framework automating the modeling process.

Marketing and Distribution Integrated System is based on GIS systems, and a unified information model of power grid equipment, basic data and topology-based systems, the use of high-tech information technology, application management and distribution line losses quarter field of network construction planning, customer outage management and other integrated information platform. Energy management system implementation ultimate goal is to achieve through intelligent system integration of existing systems be saving energy consumption and improved. In automation technology and IT based on the establishment of energy management systems, based on objective data, metallurgical, chemical, thermal, power plants and other energy consuming enterprises, energy saving most fundamental way to implement. The foundation and core of this system is that the data distribution network GIS platform, integrated measurement automation, distribution network of production, distribution network planning, distribution network automation, distribution network engineering, marketing and other systems supporting the management and reliability of power supply and distribution network planning decisions Camp with information query formulated meter reading routes and other services.

Management and automated configuration of large-scale networks is one of the crucial issues for Internet Service Providers (ISPs). Since incorrect configurations may lead to loss of an enormous amount of customer traffic, highly experienced network administrators are typically the ones who are trusted for the management and configuration of a running ISP network. In this paper, we present an online management and experimentation system with a "game" interface to train network administrators and explore what-if scenarios without having to risk the large-scale network operation. The interactive environment treats the trainee network administrators as players of a game and tests them with various failures or dynamics for real-time management and configuration of large-scale networks. To prototype the concept of "network management as a game", we modified NS-2 to establish an interactive simulation engine and connected the modified engine to a graphical user interface for traffic animation and interactivity with the player. We also conducted two user experiments using different learning methods and observed sizable improvement in the capabilities of trainees on the problem of interior gateway protocol link weight setting.

To build a flexible network than traditional transport network, the carrier ethernet technology is emerging in network industry recently and MPLS-TP technologies are being applied as a major standard technology for the carrier ethernet. However, network management technologies required to handle equipment installed in MPLS-TP network are not clear. This paper propose an efficient method to build a management network automatically without any additional configuration when network equipments are installed in MPLS-TP network. The proposed scheme reduce cost required for both equipment installation and network maintenance by minimizing configuration procedures of connecting management system with network. We evaluated the effectiveness of the proposed scheme by applying the scheme to a real MPLS-TP equipment.

The increased demand on the transport of both passengers and goods through rail systems implies higher traffic intensity and congestion on the railways, resulting in greater likelihood of accidents and also degraded passenger services. To cope with the issues, development of an integrated communication network for rails has attracted great deal of attention lately. GSM-R is such an example developed in Europe, which seems to have restrictions in providing various communication services due to network speed limit. For the reason, an LTE-based approach is under study in Korea. After the network development, operation management of the network is necessary. Design of operation management systems has been studied little and thus is the objective of this paper. To do so, a conceptual design has been carried out based on model-based approach. Specifically, a context model has first been created using the use case diagram. Then, SysML models of operational scenarios were developed for the management system. The SysML models have alternatively been expressed as EFFBD models to simulate and verify them. Consequently, the result of the conceptual system design for the operation management of the integrated wireless network is expected to be used as a basis for the detailed design later.

Service-Oriented Architecture (SOA) constructs applications by publishing services in an open network environment. In network environment individual service changes highly dynamically, it is required the system based on services to adapt to this change. But the current service management in network environment doesn’t have a good, unified management mode, management mechanism, service and quality control system, and lacks of theoretical foundation to express formal service system. In this paper, a service management framework is designed. A mechanism and method based on strategy and dynamic network environment service management are proposed. The method can effectively solve the problem of dynamic service management in network environment, and is widely used in dynamic service management based on Web services.

In this paper, we propose a novel Distributed MANET Management System (DMMS) approach to use cross layer models to demonstrate a simplified way of efficiently managing the overall performance of individual network resources (nodes) and the network itself which is critical for not only monitoring the traffic, but also dynamically controlling the end-to-end Quality of Service (QoS) for different applications. In the proposed DMMS architecture, each network resource maintains a set of Management Information Base (MIB) elements and stores resource activities in their abstraction in terms of counters, timer, flag and threshold values. The abstract data is exchanged between different management agents residing in different resources on a need-to-know basis and each agent logically executes management functions locally to develop understanding of the behavior of all network resources to ensure that user protocols can function smoothly. However, in traditional network management systems, they collect statistical data such as resource usage and performance by spoofing of resources. The amount of data that is exchanged with other resources through management protocols that can be extremely high and the bandwidth for overhead management functions increases significantly. Also, the data storage requirements in each network resource for management functions increases and become inefficient as it increases the power usage for processing. Our proposed scheme targets at solving the problems.

Network management systems provides an integrated system for sharing device information across management applications, automation of device management tasks, visibility into the health and capability of the network, and identification and localization of network trouble. By using common centralized systems and networkinventory knowledge, a Network management system delivers a unique platform of cross-functional management capabilities that reduces network administration overhead. An element management system (EMS) consists of systems and applications for managing network elements (NE) on the network element-management layer (NEL) of the Telecommunications (TMN) model. The element management system's key functionality is divided into five key areas fault, configuration, accounting, performance and security (FCAPS). Portions of each of the FCAPS functionality fit into the TMN models. This paper presents a service delivery platform which aims to develop an enterprise web application that manages these 4G network elements through various modules to meet the required Quality of Service (QoS) using RichFaces framework. RichFaces is an open source Ajax enabled component library for JavaServer Faces which allows easy integration of Ajax capabilities into enterprise application development.

This paper describes the current status of power communication systems, problems and solutions, proposed to build an integrated platform system for communications management and control.The integrated platform system is divided into four parts: Comprehensive Monitoring Subsystem, Resource Management Subsystem, Operation and Maintenance Management Subsystem, Security Management and Control Subsystem, which can monitor the resource, operation and maintenance, and security controls etc.This system can implement communication professional management, process management, user management, daily operation, maintenance work management standardization, process and automation; promote systematic and integrated for communication network, improve service management level and efficiency of operation and maintenance; and provide better support and protection for developing the grid and the smart grid.

Current telecom networks generate massive amounts of monitoring data consisting of observations on network faults, configuration, accounting, performance, and security. Due to the ever increasing degree of complexity of networks, coupled with specific constraints (legal, regulatory, increasing scale of management in heterogeneous networks), the traditional reactive management approaches are increasingly stretched beyond their capabilities. A new network management paradigm is required that takes a preemptive rather than reactive approach to network management. This work presents the design and specification of E-Stream, a predictive recommendationbased solution to automated network management. The architecture of E-Stream illustrates the challenges of leveraging vast volumes of management data to identify preemptive corrective actions. Such design challenges are mitigated by the components of E-Stream, which together form a single functional system. The EStream approach starts by abstracting trace information to extract sequences of events relevant to interesting incidents in the network. After observing event sequences in incoming event streams, specific appropriate actions are selected, ranked, and recommended to preempt the predicted incidents.

Communication network (CN) is the fundamental supporting network for communications systems, and products massive network resources in its construction and operation. Efficient organization and management of these resources is key issue to improve utilization of network resources and enhance overall performance of the CN. Based on the analysis of applying GIS on CN resources management, this paper studied key technical issues, design and implement the CN resources management system based on GIS, to improve the level of CN resources management and application.

The paper describes the integrated processing method of heterogeneous information resources of web systems, which allows for further integration and management. Our method involves the decomposition of the overall process on subprocesses of value integration, data syntax, semantics, and structure. The advantage of this approach to integration processes is the ability to execute them at the metadata level. It allows reducing the number of hits to the data of web systems, the volumes of which can be significant. The paper presents a model of the content life cycle in web systems. The model describes the processes of processing information resources in web systems and simplifies the technology of integrated automation and content management. In this work, the main problems of functional services of integration and content management were analyzed. The proposed method gives the opportunity to create tools for working out of information resources in web systems and implement the subsystem of integration and content management.

The use of computer network technology to meet the needs of information quickly and diverse, resulting in the increasingly widespread and increasing complexity of a computer network. Therefore, we need a supporting facility to be able to supervise the network element that is by using Network Management System (NMS). The NMS model established by ISO includes 5 conceptual areas, there are Fault, Configuration, Accounting, Performance and Security Management (FCAPS). One area that will be implemented in this research is Fault Management. The mechanism that will be used for error management is by detecting the occurrence of errors and sending notifications via email when the error appears, then logging report and make a diagnosis and to further recommend the solution to the error. The type of error reported in this system is errors when there is a failure of connectivity on the network device, errors due to services that are not running and not in accordance with the request, errors when high RAM usage, CPU load increases and the use of hard drives which started full. From the research results obtained, built NMS can send error notification and give solution recommendation via email to the network admin so if there is a network error, Fault Management activities can be done as early as possible so that the problem does not result in the deterioration of network quality.

Spatial information network is an important part of the integrated space-terrestrial information network, its bearer services are becoming increasingly complex, and real-time requirements are also rising. Due to the structural vulnerability of the spatial information network and the dynamics of the network, this poses a serious challenge to how to ensure reliable and stable data transmission. The structural vulnerability of the spatial information network and the dynamics of the network brings a serious challenge of ensuring reliable and stable data transmission. Software Defined Networking (SDN), as a new network architecture, not only can quickly adapt to new business, but also make network reconfiguration more intelligent. In this paper, SDN is used to design the spatial information network architecture. An optimization algorithm for network self-healing based on SDN is proposed to solve the failure of switching node. With the guarantee of Quality of Service (QoS) requirement, the link is updated with the least link to realize the fast network reconfiguration and recovery. The simulation results show that the algorithm proposed in this paper can effectively reduce the delay caused by fault recovery.

The formal structure of information models and the controlled manner of accessing and changing such models brings both flexibility and control when managing network elements. However, keeping information models synchronized and consistent across network elements and management systems is a challenging task. Today this problem is exasperated with the advent of ephemeral network functions and elements and also by the need for distributed scalable cooperating management functions running in containerized cloud deployments.

First standardization initiatives of the Cyber-Physical Systems (CPS) paradigm face a type of solutions with a top-down approach. In this view, user services and applications are transformed, decomposed and delegated until they are finally executed by hardware devices. However, most works do not describe the final execution phase, when a certain device is selected to perform an action. Therefore, in this paper we describe a management solution to coordinate the execution of low-level services in CPS. The solution employs a probabilistic selection technique based on the concept of Cost and Quality-of-Service, and includes both an orchestration algorithm and a choreography procedure. The proposal includes, moreover, a general framework explaining all the management levels and an experimental validation which evaluates the performance of the proposed technology.

The current network architecture is built on a host-centric communication model that is suitable for early network information transmission needs. However, with the emergence and rapid growth of network applications and services, the adaptability, flexibility, scalability and other defects have become increasingly prominent, and the current network architecture can't dynamically provide the required resources which according to the type of service. In order to solve the above problems, this paper proposes a service-oriented flexible network computing model (FNCM). The flexible management theory and agent technology are used to organize and manage this model to improve the intelligence, self-organization ability and management control ability of the network architecture. According to the resource performance required by the service, the fuzzy method is used to stratify and cluster the resources to form the mapping mechanism between the resource and the task. The model can not only effectively achieve the intelligent adaptation of services and network resources, and reduce the scale of the problem.

The virtualization and softwareization of network functions, controls, and applications are promising as they optimize costs and processes while bringing new value to the network infrastructures. However, the centralized reliability management over the complex softwareized network poses both scalability and latency challenges on the failure recovery process. In this paper, we propose a Network Architecture-aware Reliability Management Schemes (NetAware) to efficiently orchestrate different reliability monitoring mechanisms over SDN network architecture and synchronize the control messages among different controllers and applications. NetAware facilitates many common reliability monitoring factors for the registered applications by analyzing both off-line and on-line network architecture information such as network topologies, virtualization, and protocols. NetAware consists of a High Availability Registration Platform (HARP) and a Topology Aware Reliability (TAR) discovery facilities. A prototype is implemented on Cisco’s OpenDayLight (ODL).

The best advantage of cloud environment is elasticity. Although cloud-hosted ICT services gain an ability to flexibly change their size and granularity, deep knowledge and much experience are required for administrators to stably operate ICT services in such fluctuating environment. Various attempts on knowledge-based systems are made to reduce burden on administrators. However, knowledge-based systems necessitate management knowledge appropriate to ICT service configuration, and consequently a burden on maintaining knowledge base is not negligible in fluctuating environment. We propose service oriented network management with knowledge-based network management support system. Proposed system is modularized and can be applied to fluctuating environment with less burden. We demonstrate the effectiveness of our proposal through experiments using implemented prototype system.

As many applications today migrate to distributed computing and cloud platforms, their user experience depends heavily on network performance. Software Defined Networking (SDN) makes it possible to obtain a global view of the network, introducing the new paradigm of developing adaptive applications with network views. A naive approach of realizing the paradigm, such as distributing the whole network view to applications, is not practical due to scalability and privacy concerns. Existing approaches providing network abstractions are limited to special cases, such as bottlenecks exist only at networks edges, resulting in potentially suboptimal or infeasible decisions. In this paper, we introduce a novel, on-demand network abstraction service that provides an abstract network view supporting not only accurate end-to-end QoS metrics, which satisfy the requirements of many peer-to-peer applications, but also multi-flow correlation, which is essential for bandwidth-sensitive applications containing many flows to conduct global network optimization. We prove that our abstract view is equivalent to the original network view, in the sense that applications can make the same optimal decision as with the complete information. Our evaluations demonstrate that the abstraction guarantees feasibility and optimality for network optimizations and protects the network service providers' privacy. Our evaluations also show that the service can be implemented efficiently; for example, for an extreme large network with 30,000 links and abstraction requests containing 3,000 flows, an abstract network view can be computed in less than one second.

In the paper the channel reliability of communication network with common set of standby radio stations for real conditions of Air Traffic Management (ATM) is discussed. ATM systems represent essential infrastructure that is critical for flight safety and communication is a key element in the present ATM system. As additional method of improving the reliability of the ATM communication network a dynamic management of backup modes with two-stage mode of redundant elements is proposed. Mathematical model of the channel reliability is developed. Comparative analysis of redundancy effectiveness for developed and used structure of ATM communication network is performed.

Context. The problem of growth of the mobile data traffic and the number of services becomes global, moreover, volume and frequency of control traffic transmitted through the network are increasing, and therefore there is a need for its effective management to ensure the quality of service required by users and optimal use of mobile network resources. In such circumstances, the load on the server that is created in the process of establishing the connection and its serving has its considerations. Dynamic resource provisioning is a useful technique for handling the variations seen in communication systems workloads. Virtualization technology allows to implement this approach. An analytic model of a system would be attractive as it would be able to evaluate system characteristics under a wide range of conditions, and to be computed comparatively easily. It is also can incorporate numerical optimization techniques for system design. Objective. To improve the efficiency of mobile network through optimal resource allocation in telecommunication environment. Method. Analysis of the known publications devoted to virtualization of network functions of mobile network has shown the modeling approach to resource allocation and also has shown the absence of decisions on important issues of this process (performance of management, load prediction system). Results. An approach to model and investigate hybrid dynamic system of network functions resource management, where resources are provided to virtual nodes dynamically and opportunistically based on predicted needs, is proposed. Conclusions. In the paper the problem of provisioning system design for virtualized network functions is solved. A method for adapting the size of network function’s resource allocation control interval is proposed that provides dynamic configuration of the system, reducing excessive service data transmitted in the network, and decrease the load of network nodes. The workload service system model is built which outlines a method of workload forecasting, which takes into account long-term accumulated statistics and recent trends observed in a network that allows a rational level of management costs and final values of quality of service.

Mobile networks are moving into the 5G which is envisaged to face various complexity of network management caused by the intensifying data traffic demand, diverse wireless environments, and multiple service necessities. The requirements are strong to propose new network architecture aiming to meet heterogeneous services demands coming from various technologies such as LTE, WiFi and beyond. It is then challenging to tackle the mobility management and more specifically vertical handovers which aim to maintain ongoing session. As a proposed technology, Software-defined network (SDN) that permits network operators to easily introduce new services and to simplify network management. Adding to this, Distributed Mobility Management (DMM) which is emerging as a new trend to blueprint future mobile network architectures in order to overcome the centralized aspect of the current mobile network. Due to the foreseen domination of IPv6, a combined solution is discussed to simplify users' mobility and to assure the QoS of different applications. Based on SDN and DMM, IPv6 Routing Header will be the main suggested solution to guarantee mobility management in heterogeneous network.
