P2P 之 UDP穿透NAT的原理與實現（附源代碼） 原創：shootingstars 參考：http://midcom-p2p.sourceforge.net/draft-ford-midcom-p2p-01.txt baidu 論壇上經常有對P2P原理的討論，但是討論歸討論，很少有實質的東西產生（源代碼）。呵呵，在這里我就用自己實現的一個源代碼來說明UDP穿越NAT的原理。 首先先介紹一些基本概念： NAT(Network Address Translators)，網絡地址轉換：網絡地址轉換是在IP地址日益缺乏的情況下產生的，它的主要目的就是為了能夠地址重用。NAT分為兩大類，基本的NAT和NAPT(Network Address/Port Translator)。 最開始NAT是運行在路由器上的一個功能模塊。 最先提出的是基本的NAT，它的產生基于如下事實：一個私有網絡（域）中的節點中只有很少的節點需要與外網連接（呵呵，這是在上世紀90年代中期提出的）。那么這個子網中其實只有少數的節點需要全球唯一的IP地址，其他的節點的IP地址應該是可以重用的。 因此，基本的NAT實現的功能很簡單，在子網內使用一個保留的IP子網段，這些IP對外是不可見的。子網內只有少數一些IP地址可以對應到真正全球唯一的IP地址。如果這些節點需要訪問外部網絡，那么基本NAT就負責將這個節點的子網內IP轉化為
