| 摘 要： | 本文提出了一种基于分布式名字解析机制的P2PSIP方案.通过P2P技术实现了SIP的位置服务,解决了现有网络电话在部署中存在的"单点失效"等性能瓶颈问题,具有良好的可扩展性和可靠性.针对大规模应用中可能会出现的系统查询效率下降问题,在设计基于分布式名字解析机制的P2PSIP过程中增加了缓存机制.仿真证明该机制可有效地提高系统查询效率.

| Abstract: | This paper presented a scheme of distributed name resolution mechanism based P2PSIP,implemented the SIP location services through P2P technology,solved the problems about the performance bottleneck like single point failure in the deployment of the existing SIP phones.This scheme was with good scalability and reliability.For large scale application might cause the decline of the system query efficiency,this paper designed a caching mechanism in the System.The simulations showed that the caching mechanism co... |
