摘　　要：通过对全分布式结构化P2P网络和SIP(Session Initiation Protocol)协议的详细分析,充分发挥全分布式结构化P2P网络特性,采用分布式哈希表DHT(Distribute Hash Table)结构和CHORD结点搜索算法,设计出一个新的基于分布式哈希表DHT的P2P-SIP网络电话系统,克服了原有SIP网络电话系统需要集中式目录服务器的缺点,方便网络电话的管理,降低网络电话组建费用。Through the analysis of the P2P network based on distributed structured topology and SIP protocol, the advantage of this P2P network is fully exploited. Based on the DHT structure and the CHORD node searching algorithm, a new type of P2P-SIP Internet-telephone system is designed. The shortcoming of the centralized directory scheme in traditional SIP Internet-telephone is overcome. The management of Internet-telephone is made easy,and the cost of the construction of Internet-telephone system is reduced.
