摘要
讨论了P2P(对等网络)的基本概念,NAT的产生原因和一个NAT的具体例子;然后针对UDP连接分别讨论了单一NAT环境和对立NAT环境这两种网络架构下P2P应用程序的穿透。此外,还简略讨论了TCP连接下P2P应用程序对NAT环境的穿透问题。
This paper introduces the basic concept of P2P network, then describe the essential reason of NAT and give an example of NAT. Moreover, this paper describe the methods used by the current Peer-to-Peer (P2P) applications to communicate through network address translators (NAT) over UDP connection and TCP connection.
