| 摘 要： | 针对SIP音视频通信应用的快速发展与IPv4地址资源不足的矛盾,提出了NAT穿越机制.现有的NAT穿透方案或者扩展性不好,或者未采用标准的协议栈,或者对移动性支持较差.文中提出了一种新的SIP协议穿越NAT机制(NATUT),采用使客户端主动修改SIP协议域值为NAT映射后的公网地址的方式,实现了SIP协议的通畅穿越NAT设备.测试结果表明,该机制能较好地解决了扩展性等方面的问题. |

| Abstract: | As a result of the inconsistency between the rapid development of SIP-based audio/video communication applications and the shortage of IPv4 adresses, the NAT traversal method has been raised. To solve the existing problems such as the poor expandability during NAT traversal and nonstandard protocoI stacks, a new strategy called NATUT is proposed, in which the client is asked to switch these private address to public address. The result shows that the new solution is evidently effective and convenient. |
