RFC4747 : Network Address Translation (NAT) Behavioral Requirements for Unicast UDP
此篇 RFC 提供了一些方法,說明當應用程式遇到不同類型的 NAT 時,應該如何處理UDP封包,才比較容易在NAT環境下運作無誤(NAT打洞容易成功)。例如線上遊戲或是視訊會議等應用程式。
The goals of this document are to define a set of common terminology for describing the behavior of NATs and to produce a set of requirements on a specific set of behaviors for NATs.
