Abstract
Network Function Virtualization (NFV) and Software Defined network (SDN) intend to deliver Next Generation Networks (NGN) related services over an intelligent, cost effective and cloudified infrastructure. This paper discusses a new NGN design based on cloud services such as NFV and SDN in order to improve network scalability, elasticity, usage efficiency and resiliency while decreasing cost. In this paper, we discuss the detailed architectural design along with the functionality of each element of the design. The new design will be investigated against some of the NGN related challenges to prove its efficiency to deliver services. Analysis in terms of performance, flexibility and Deployment Complexity will be performed to explore possible enhancements to the proposed design.
