摘要

在SIP服务实现中

传统的多服务器独立工作方案存在资源利用率低和信息更新代价大的问题

基于对等计算的思想

将所有的SIP服务器组织到覆盖网中

对Chord路由表的结构进行改进

采用基于等距地址Hash的多副本发布策略

提出一种改进的多服务器协作方案.给出了该方案与多服务器独立工作方案、基于传统Chord的服务器协作方案的性能比较分析.仿真结果表明

该方案能够确保较高的消息查询成功率和转发速度

减小网络流量开销.

Abstract

For traditional SIP service implemetation

severs work individually

and there exist problems such as low availability of resources and high cost of information update.Based on the idea of peer-to-peer computing

we built a Chord overlay with all SIP servers

modified the route table of Chord

distributed replicas with equal-distance address Hashing method

and thus proposed an improved multi-server cooperation method.Theoretical performance comparison was made among our new method

traditional individually-working method

and Chord-based cooperation method.Simulation results showed that our method can guarantee high success ratio of query and speed of forwarding

and decrease overhead of network traffic.
