【摘要】 针对H.323协议与防火墙和NAT设备共处时的问题及现有解决方案的不足,提出了一种建立在运输层协议上的隧道穿越技术的解决方案:隧道机制逻辑上由客户和服务器端两部分组成,采用SocksV5协议在客户端和服务器之间建立一条或多条TCP/UDP隧道,并制订了客户端和服务器端的工作规则,从而使H.323通信中的各种信令和媒体数据流能透明的穿越防火墙和NAT设备.仿真结果表明,相比其他解决方案,本方案可以更好地解决H.323通信中穿越防火墙和NAT设备这一问题.更多还原

【Abstract】 Aiming at the problems of 3 firewalls and NATs in H.323, this paper proposed a novel solution based on the tunnel traversing mechanism at the transport layer. This solution, consisting of client and server logically, is used to traverse the firewalls and NATs in H.323, based on one or more tunnels established socks V5 protocol and the rules between the clients and servers. This solution is feasible proved by an emulator.更多还原
