摘要 S IP是一个基于文本的应用层控制协议.S IP协议本身不能保证S IP信令和媒体流安全地穿越NAT和防火墙,从而限制了其在广域网上的应用和发展.本文通过对现有S IP协议栈资源进行功能扩展,并增设媒体中继服务器对媒体流数据包进行中转,完成了对所有类型NAT的穿越. SIP is a text-based application-layer protocol. It can't resolve NAT traversal problem, which deeply cumbers its development on WAN. This paper provides a complete solution in detail by extending SIP protocol stack and relaying media data through a server that resides on the public Internet.
