摘要

媒体分发服务器是网络视频监控平台中负责流媒体分发的重要模块。网络地址转换器（Network Address Translator

NAT）能很好地解决IPv4地址资源匮乏的问题

但同时也给各个私网用户之间或私网与公网用户之间的通信带来了障碍。文章主要介绍这种NAT障碍的形成

并给出了会话初始协议（SIP）下媒体分发服务器实现NAT穿越的一种方案。

Abstract

A media distribution server is an important module in an IP video surveillance system platform that is in charge of streaming media distribution.Though able to cover the shortage of IPv4 address resource

the IP Network Address Translator（NAT） brings about obstacles in the communications between the users in various private networks or between those in the private and public networks.This article mainly introduces the formation of such obstacles and gives an SIP-based approach for the media distribution server to implement NAT transversal.
