摘要 SIP协议是VoIP领域中最重要的协议之一。在现有的SIP协议里使用了服务器,带来了需要手工配置、维护,以及扩展性较差等问题。为解决这些问题,该文在分析目前VoIP系统的基础上,借鉴Skype结构,结合哈希表查询P2P网络,提出了一种纯P2P-VoIP结构,这种结构具有零配置和易于扩展等特点。 SIP is one of the most important protocol in the area of Vole Since dedicated serves are used, SIP systems are typically needed to be configured and maintained by hand, and the scalability is limited. To solve these problems, the paper analyses the VoIP and Skype system, and proposes a pure P2P-VoIP architecture based on DHT overlay. The architecture is self-organized and provides good scalability.
