Abstract:

Controlled by the background server, application of the traditional session initiation protocol (SIP) will face risks such as failure of one node server and crash of the whole network due to attack. Meanwhile, user communications are restricted. The SIP application based on peer-to-peer(P2P) can realize user registration, joining, seeking, retrieval and routing. It has advantages of balanced communication load and system robustness. With the evolution from SIP to P2P, reliability and scalability of the SIP network will be improved, making interconnection between traditional communication system and SIP network easier.
