| 摘 要： | 结合P2P-DHT(CHORD)节点搜索算法，对SIP协议进行扩展，把基于DHT的全分布式结构化P2P网络架构引入基于SIP协议的网络电话系统，设计了一种新型的P2P-SIP网络电话系统。该方案克服了原有系统需要集中式目录服务器的缺点，在中小规模的网络电话领域具有很好的应用前景。

| Abstract: | This paper extends the SIP protocol with the combination of P2P-DHT(CHORD) node-searching algorithm, introduces the DHT-based fully distributed P2P architecture into the traditional SIP Internet-telephony, and designs a new type of P2P-SIP Internet telephony system. The fully distributed architecture design scheme overcomes the shortcomings in centralized directory scheme using traditional SIP Internet-telephony and will have bright application prospects in small and middle Internet telephony field. |
