摘要
VoIP语音视频流对NAT/F irewall的穿越已经成为语音数据业务开展过程中最大的障碍。Fu ll Proxy提供了一种NAT/F irewall穿越的有效途径,具有很强的适应性和透明性。深入讨论了Fu ll Proxy的实现原理和基于Fu ll Proxy的整个呼叫流程,最后在一个嵌入式双CPU系统的基础上实现了一个Fu ll Proxy。
The traversing of the media and video streams across NAT/Firewall has been the greatest obstacle in the development of NGN service. Being a practical way of NAT/firewall traversing, Full Proxy shows its expansibility. In the first place of this paper we analyze the theory of Full Proxy and the call flow based on the Full Proxy. In the end, we realize a Full Proxy on an embedding system with two-cpus.
