Abstract

The Next Generation Networks (NGN) means All-Optic-Networks needed seamless connectivity between heterogeneous (multi-domain) networks maintained by different Internet Service Providers (ISP). Routing and Wavelength Assignment (RWA) certainly be required for packet routing from source to destination in this All-Optic multi-domain network. To route in a single Autonomous System (AS) Open Shortest Path First (OSPF) lonely can perform, but for a Network with multiple Autonomous Systems (multi-domain) may require an algorithm that satisfies Wavelength Continuity Constraint (WCC) for RWA and also need to maintain communication with Border Gateways. Optical Border Gateway Protocol (OBGP) with OSPF and WCC can meet the requirements. The proposed algorithm is simulated in various scenarios like SISO, SIMO, MISO, and MIMO. Few metrics like best shortest path, the wavelength available for packet routing, path length and latency are identified for mentioned scenarios. [ABSTRACT FROM AUTHOR]

Abstract

Cloud computing technologies and infrastructure facilities are coming up in a big way making it cost effective for the users to implement their IT based solutions to run business in most economical way. Many intricate issues however, have cropped-up which must be addressed to be able to use clouds the purpose for which they are designed and implemented. Among all, fault tolerance and securing the data stored on the clouds takes most of the importance. Continuous availability of the services is dependent on many factors. Faults bound to happen within a network, software, and platform or within the infrastructure which are all used for establishing the cloud. The network that connects various servers, devices, peripherals etc., have to be fault tolerant to start-with so that intended and un-interrupted services to the user can be made available. A novel network design method that leads to achieve high availability of the network and thereby the cloud itself has been presented in this paper. [ABSTRACT FROM AUTHOR]
