网络多媒体应用的SIP和QoS网络叠加模型

Model of SIP and QoS for the multimedia application

SIP和IP服务质量是为解决IP网络多媒体应用的需要而提出的,SIP和IP服务质量的融合为多媒体应用提供了更好的解决方法,文章在对SIP及其扩展的简要介绍的基础上,分析了增强特性SIP代理服务器在各种IP服务质量模型下,是如何与QoS网络的交互,从而引出了SIP的IP网络服务质量的叠加模型。

SIP and QoS are proposed for the need of soluting the multimedia application in IP network. The convergency of SIP and QoS provides a better solution for the multimedia application.Based on the inroduction of SIP and its extension,this paper analyses how the SIP proxy interacts with varied QoS network ,and then derivates the aggregate network model of SIP and IP QoS .
