| 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-workin... |
