摘要:

本文首先分析了多媒体通信面临的FW/NAT(firewall /network address translation,防火墙和地址转换)穿越问题,然后对UPnP技术进行了介绍,包括其基本概念、网络组成、协议栈和工作原理等内容。文中还介绍了UPnP对因特网接入网关的支持,分析了UPnP穿越FW/NAT的原理。最后以SIP为例研究了UPnP在多媒体通信穿越FW/NAT中的应用,提出了SIP穿越FW/NAT的解决方案。

关键词: UPnP, 防火墙, NAT穿越, 多媒体通信, SIP

Abstract:

This paper describes the problem of FW/NAT traverse at first,then UPnP technology is introduced,include the basic concept,network components,protocol stack and it's work process.We also analyze the way UPnP support for FW/NAT traverse after the introduction of Internet access gateway in UPnP network.Finally,we research the application of UPnP for FW/NAT traverse in multimedia communication system taking SIP as example and provide a solution of FW/NAT traverse for SIP.

Key words: UPnP, firewall, NAT traverse, multimedia communication, SIP
