  • Received:2006-03-23 Revised:1900-01-01 Online:2007-02-21 Published:2007-02-21

摘要: 本文提出了一种TCP协议穿透Symmetric NAT的解决方案,该方案利用Symmetric NAT的端口可预测性,采取双方同时打开TCP连接技术,实现了在不同Symmetric NAT之后的主机间的TCP直连,经测试表明具有理想的连接成功率。

Abstract: A solution for symmetric NAT traversal of TCP is proposed. Based on port prediction, direct TCP connections between hosts behind symmetric NATs can be established with the help of simultaneous TCP open. Experiment results demonstrate that this solution works well for symmetric NAT traversal of TCP.
