摘要:
会议初始化协议(SIP)凭借其简单,易于扩展等优点,已成为未来网络发展的重要应用协议.它采用Client/Server(C/S)的结构体系,当系统业务量增大时,系统容易达到性能瓶颈,成为其技术发展的障碍.基于分布式点对点(P2P)网络的去中心化特征,正好弥补了SIP的这一缺陷.因此,首先提出了一种基于P2P网络架构的SIP视频会议系统模型,将现有SIP视频会议系统的C/S架构改进成为P2P的混合网络体系结构.这既发挥了P2P无中心的优越性,又体现了SIP的C/S模式的优点.其次,阐述了该系统主要功能模块以及相关程序设计.最后介绍了该系统的主要信令工作流程.
Abstract:
Session Initiation Protocol (SIP)is a key protocol for next multimedia communication networks with its simplicity and extensibility. Due to its Client/Server(C/S)architecture, when the system traffic increases, the system performance will emerge a bottleneck easily, which is a technological obstacle of SIP application and development. The paper presents a novel architecture model of SIP video conference system based on P2P network, which improves present C/S architecture based SIP to mixed network architecture based P2P. It not only has advantages of distributed architecture like P2P system, but also has advantages of C/S architecture in the SIP system. Then the paper discusses the main functional modules and programming design. In the end, the important signaling operation flow is introduced.
