| 摘 要： | 随着宽带网络技术的发展,基于IP网络的多点视频会议系统得到了广泛的应用.为了解决网络地址资源匮乏的问题,大量企业和部门的网络采用内部IP地址,通过NAT路由器与公共网络通信,但是NAT技术在某些情况下又给用户之间的通信造成了一些困难.深入研究了基于UDP Hole Punching穿透NAT路由器进行通信的方法,在此基础上设计并实现了一套实用的多媒体多点视频会议系统.

| Abstract: | With the rapid development of computer network technology, multi-point video conference systems based on IP network are widely used in many companies and organizations. At present, there is a growing shortage oflP address in Internet. In order to solve this problem, most companies and organizations adopt inside IP address to connect Internet via NAT technology. But NAT has also its own flaws, Which can cause some difficulties for the transmission between two hosts, The UDP-hole-punching-based NAT router traversing technology is researched deeply. On this basis, a practical multimedia multi-point video conference system is designed and implemented. |
