NGCN: A P2P-based distributed next generation core network towards 4G

With the development of mobile Internet and distributed technologies, the traditional telecommunications network is subject to many challenges. Skype, a popular peer-to-peer VoIP (Voice over IP) application, shows the gigantic advantage of distributed communication. Therefore, we are trying to design a Next Generation Core Network (NGCN), which utilizes distributed technologies such as P2P, cloud computing, virtualization, etc. It can not only provide traditional telecom services, but also better support the high-bandwidth consumption services in 4G, such as Streaming, file-sharing and so on. This paper first introduces the NGCN architecture, layered architecture model and the P2P overlay design, and then analyzes the future network capabilities demands. The NGCN we provide is distributed, self-organization and scalable.
