This paper presents an architecture to provide endto- end per-user services with support to client mobility, designed according to the SDN and NFV paradigms. Our service platform dynamically configures and launches service requests when the client connects to the network, which are used by a multidomain orchestration system to arrange the required network configuration and computational resources...
Software Defined Networking (SDN) is a powerful approach that enhances network control and management, and provides a flexible way to develop network applications. However, scalability of SDN networks is an important concern for many network operators. The main peculiarities of SDN when applied to an Internet Service Provider (ISP) network are the large geographical extension and the need of in-band...
Scalability of Software Defined Networking (SDN) approach is one of the key issues that many network operators are willing to address and understand. Indeed, the promised programmability and flexibility of a SDN network is paid with a non-negligible control traffic exchanged between the network nodes and the SDN controllers. We consider a network controlled by a real OpenFlow-enabled controller, i...
