Abstract

In an increasingly interconnected world, new opportunities for telecom-based services are emerging. Innovative applications profit from cloud versatility and scalability, but require a platform to combine the optimized 5G network fabric with the advancements in the domain of cloud computing, Software Defined Networking (SDN) and Network Function Virtualization (NFV). In this multi-domain context, we find that available service platforms are lagging, because they tend to be tightly coupled to a constrained set of technologies. In practice, we need the flexibility to deploy different microservices over a heterogeneous range of infrastructure types, aggregating various virtualization, orchestration and control mechanisms. Moreover, the integration of the service requires collaboration among a wide mix of actors (e.g. developers, operators, hardware/software vendors, infrastructure/service providers or vertical integrators). We propose a next-generation Platform-asa-Service (NGPaaS), devised as a modular framework for the development and operation of network services, while targeting a high degree of both customization and automation. The presented architecture is built around a workflow-based orchestrator which coordinates custom-built tasks across a tailored group of specialized infrastructure or platforms. We also explain how NGPaaS enhances DevOps-principles, to achieve a more efficient integration process across the many isolated administrative domains in the modern telco landscape.

Abstract

Platform-As-A-Service (PaaS) systems offer customers a rich environment in which to build, deploy, and run applications. Today’s PaaS offerings are tailored mainly to the needs of web and mobile applications developers, and involve a fairly rigid stack of components and features. The vision of the H2020 5GPPP Phase 2 Next Generation Platform-as-a-Service (NGPaaS) project is to enable “build-to-order” customized PaaSes, tailored to the needs of a wide range of use cases with telcograde 5G characteristics. This paper sets out the salient and innovative features of NGPaaS and explores the impacts on Operational Support Systems and Business Support Systems (OSS/BSS), moving from fixed centralized stacks to a much more flexible and modular distributed architecture.

12. T-NOVA: An Open-Source MANO Stack for NFV Infrastructures.

Abstract

One of the primary challenges associated with network functions virtualization (NFV) is the automated management of the service lifecycle. In this paper, we present a full software-based management and orchestration (MANO) stack which operates with OpenStack and OpenDaylight controllers and has the in-built functionality to automate the key phases of the NFV service lifecycle, namely resource discovery and matching, service mapping, service deployment, and monitoring. The MANO stack is being implemented by the EU FP7 project T-NOVA, with the components being released as open-source software. Service mapping and service deployment solutions developed in the scope of T-NOVA are presented in detail. As a proof-of-concept, we evaluate the performance of a virtualized traffic classifier network function, demonstrating the gains of virtualized hardware acceleration. [ABSTRACT FROM PUBLISHER]

Abstract

This paper presents an analysis of requirements to Software Defined Network (SDN) Controllers (SDNC), from the point of view of the Telco’s Next Generation Platform as a Service (NGPaaS) functional and architectural needs. Numerous requirements have been identified, which can be grouped in 4 categories: domain-based, modularity-based, related to the SDN and Network Function Virtualization (NFV) integration and finally policy-based. These requirements are later mapped into the ONOS SDN controller, with the scope of identifying possible gaps and points of improvement.
