摘要
目前的信息共享系统普遍存在着对内网终端的防火墙穿透问题。针对这个问题.本文在现有的UDP穿透和TCP穿透两种方案基础上对实际应用中的各种可能传输情景进行分析,提出了一种UDP协调TCP穿透防火墙的技术,利用UDP作为控制信息的传输方式来实现TCP穿透防火墙,并给出了这一方法的实现——独立于应用的网络转接器XIPSwitch。该实现方法经进一步完善可解决现有信息共享系统对内网终端的防火墙穿透问题。
In the current information sharing systems, there is a problem of firewall penetration. As for this problem and based on the exiting TCP and UDP penetration schemes,we analyze all kinds of possible transmission scenarios in practical applications,and then present a technique of UDP coordinating with TCP to penetrate firewalls. Finally, we present the realization of this methodta network connector XIPSwitch which is independent of applications, the realization method can further solve the firewall penetration problem of the internal terminal in the existing information sharing systems.
