摘　　要：针对SIP服务在C/S方式下网络电话会议部署中可能出现的单点失效和性能瓶颈问题,提出一种新型的分层服务下的P2P-SIP网络电话会议解决方案,在VIP和Ordinary两个层次上分别通过直传和应用层组播分发媒体数据流,该设计基于分布式结构化P2P网络,采用信令集中、媒体流分布的会议模型,能满足参与人数较多的大型VoIP网络会议的需要。To solve the problems of single-point failure and performance bottleneck the SIP services may have in the deployment of teleconferencing under C/S mode ,this paper gives a new type of P2P-SIP teleconferencing as a solution with layered services that distribute media data stream using direct and application layer multicast transmission respectively on VIP and Ordinary layer. This design is based on distributed and structured P2P network with the conference model of signalling centralized and media stream distributed, and can meet the needs for the VoIP teleeonferencing with a larger amount of participants.
