基于P2P+SIP的流媒体服务系统的设计

摘要

从网络多媒体系统的业务需求和功能模块分析出发,提出了在底层P2P网络上建立流媒体服务系统,并使用SIP技术进行呼叫、建立、断开等系统的功能.该体系结构保证了在P2P系统中的零配置、鲁棒性和适应性,另外还可以与现有的SIP设备连通.虽然增加了呼叫建立传输时间,但由于信息是由双方直接发送,无论是C/S结构还是P2P结构,都不经过SIP代理服务器,因此不影响信息延时.%This paper studies multimedia system from the network business requirements and functional module, propose the establishment of the underlying P2P streaming media service network system, and a call using SIP technology to establish, disconnect and other system functions.The architecture guarantees that the P2P system, zero configuration, robustness and adaptability, in addition to connectivity with existing SIP device.Although the increase of call setup transmission time, but because information is sent directly by the parties, whether it is C/S structure or P2P structure, not through the SIP proxy server, it does not affect the message delay.
