NAT(Network Address Translators)，网络地址转换：网络地址转换是在IP地址日益缺乏的情况下产生的，它的主要目的就是为了能够地址重用。NAT分为两大类，基本的NAT和NAPT(Network Address/Port Translator)。 最开始NAT是运行在路由器上的一个功能模块。在这里我就用自己实现的一个源代码来说明UDP穿越NAT的原理。-NAT (Network Address Translators), Network Address Transl

可信任的UDP协议,可以实现可控制速率,还有实现NAT 穿越,非常好-Trusted UDP protocol, can realize control rate, and to realize NAT through, it was very good

通常情况下，当进程使用UDP 和外部主机通信时，NAT 会建立一个Session ，这个Session 能够保留多久并没有标准，或许几秒，几分钟，几个小时。(Typically, when a process uses UDP to communicate with an external host, NAT creates a Session, how long the Session can hold and does not have a standard, maybe a few sec
