With the development of Internet, more and more people believe that the future telecommunication network will be constructed based on IP technology. Session Initiation Protocol (SIP), which has advantages of simple entrainment method, good scalability and open protocols, is the main research topic on Voice-over-IP (VoIP). Although the client-server architecture currently used by SIP is simple and easy to maintain, it has limitation wherein service quality needs to rely on server performance. To improve this, the Internet Engineering Task Force (IETF) has created a draft to discuss the application of P2P (Peer-to-Peer) architecture in SIP, and we hope that the draft can help to provide good SIP service quality on P2P architecture, such as good fault tolerance and transmission performance.
Our research is based on Chord architecture and aims to make P2P SIP architecture in an embedded User Agent. For the SIP internet telephone feature, we adjusts Chord algorithm to meet SIP internet telephone requirements. Furthermore, the adjustment to Chord makes it more applicable to the environment that users continuously join or leave, so that the revised Chord can be implemented with SIP protocol to achieve the P2P SIP goal.
