Cloudified Next Generation Network (NGN) Infrastructure to Provide Triple Play Services

Abstract

The service delivery networks experienced many transformations during the past decade mean while virtualization constitutes the next big phase in the operators’ strategies. One of the most promising technologies which might step in the coming years is Software Defined Networking (SDN), a more mature technology in data centers, which strives to revolutionize the current Next Generation Network (NGN) architecture. However, the integration of SDN components into the legacy network and the transition between phases need to be carefully addressed. This thesis aims to develop a new NGN (the network delivers triple play services) virtualization based architecture in order to solve challenges that traditional architecture faces. On-demand capacity expansion, network elasticity and high expenses is some of the challenges that the new model aims to solve through the deployment of Network Function Virtualization (NFV) and SDN. By describing the simulation details of the cloudified architecture, one of this thesis goals is to present the trade-off between preserving the traditional architecture and the actual benefits, along with the challenges that operators may face in adopting SDN and (NFV) in their deployments. To achieve this, a testbed was used based on a network simulation tools. The obtained results emphasize the flexibility in deploying such solutions. Furthermore, a detailed graphs of triple play services’ performances are presented.
