p2pNAT穿透的解决方案

这里面有3篇关于tcp如何打洞建立p2p连接的文章，介绍了原理，也有实例的代码。-There are three articles to establish p2p connection on tcp how holes, introduced the principle, there are also instances of code.

根据理解 我用例子详细 讲解了udp 打洞原理,p2p 的实现必须要解决这个问题。-According understand I use examples explain in detail the the udp holes principle p2p realization must solve this problem.
