| 摘 要： | P2PSIP用P2P算法实现SIP的位置管理功能,解决了单点失效问题,有良好的可扩展性,将成为VoIP的关键技术。现有相关研究缺乏对不同网络互通的深入探讨。提出P2PSIP网络与PSTN的一种新颖的互通机制,并且基于该机制设计了一个易于实现的P2PSIP终端与PSTN电话互通的原型系统。互通的关键设计是一个具有双重身份的网关,在P2PSIP网络中作为对等端,在PSTN中负责连接电话机。经测试分析,该互通机制可以应用于实际网络,实现P2PSIP网络和PSTN之间的会话建立。

| Abstract: | P2PSIP implements the function of location management of SIP using P2P algorithm and has resolved the problem of single-point failure,it has good scalability and will become the key technology for future VoIP.Interconnection mechanisms between different networks should be studied in depth but current researches do not work a lot in this regard.In this paper,we propose a novel interconnection mechanism between P2PSIP network and PSTN.Furthermore,a prototype for facile achieving sessions between the P2PSIP ho... |
