Description: SIP称为会话发起协议（Session Initiation Protocol)。SIP是Internet工程任务组（IETF）提出的建议中的一项协议，其目的是为了替代H.323的部分协议，主要是考虑到在下一代网络（NGN）中，由于IP产品和IP网关将在网络中得到大规模使用和集成，使得端到端都可以采用IP以实现纯IP的业务应用；而基于纯IP的SIP借鉴了HTTP和SMTP，结构简单并具有可扩充性和可扩展性。此外，SIP还提供良好的QoS支持。对于NGN在IP网络上实现VOIP和多媒体通信来讲，SIP在全面满足NGN特性要求的应用上具有独特的优势，必将成为下一代网络VOIP的重要解决方案。
