一种新的基于P2P-SIP分布式结点发现的网络电话研究与设计

Research and Design of a New Type of Internet Telephony Based on P2P-SIP Distributed Node Discovery

通过对P2P技术和SIP协议的详细分析,充分发挥P2P技术分布式特性,采用CHORD结点搜索算法,设计出一个基于P2P-SIP的分布式结点发现的网络电话系统,克服了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。

By analyzing the P2P technology and SIP protocol, the advantage of distribution of P2P technique has been fully exploited. Using the CHORD node searching arithmetic, a new type of Internet-telephony system based on P2P-SIP distributed node discovery has been designed and whereas has solved the disadvantage of centralized directory server in SIP Internet-telephony, made the management easy and reduced the system charge.
