基于ICE方式语音通信原理的研究与应用

Research and application of video communication based on interactive connectivity establishment

基于IP的语音通信在复杂的网络环境中,最大的困难就是如何穿越各种各样的IP网络地址变换器(NAT)。目前比较常见的解决方案有STUN、TURN和Proxy等,但是它们在兼容性以及通用性上都有很大的局限。探讨基于ICE方式的语音通信原理,在实时通信系统上实现基于ICE方式的语音通信模块,测试多种网络环境下的通话情况。

The biggest difficulty in a complex network environment based on IP voice communications was how to through a variety of NAT. Currently the common solution was STUN, TRUN, Proxy, and so on. But their compatibility and versatility had great limitations. It was discussed the methods based on the ICE principle, implemented the voice communication module in Real Time Communication System based on ICE, tested the call in variety of network environment.
