Study of VI rtual Network Function Development Based on Software Defined Networking and Network Function VI rtualization (I)

With the rapid development of cloud computing, mobile broadband network, and Internet of Thing, it causing a considerable demand of network resources allocation, data processing and service management,and also driving an inevitable transition of traditional network infrastructure. Both Software Defined Network (SDN) and Network Function Virtualization (NFV) technologies are not only transforming network infrastructure from complicate physical entities to virtual and programmable nodes, but also bringing significant change to the development of ICT. The goal of this project is using SDN and NFV technologies for virtual network function provisioning. Design and implement an NFV management system prototype combined SDN technique to achieve network service flexibility.This project is over two years. The first year will developing NFV virtualization management prototype system based on virtualization technology. The system can establish the Virtual Network Function images to provisioning network services and provide creating, duplicating and deleting functions. The second year continues the results of the first year. The design and implement of the service chain routing and bandwidth management mechanisms based on SDN/OpenFlow centralized control architecture will address in this year.This project will establish a basis for the service management of virtualized network based on SDN, NFV and SFC technologies, and extend its results to practical scenarios.
