UDP 是一种应用广泛的传输协议,具有传输速度快、简单等特点,但其面向无连接的特性,使得应用UDP 传输具有不可靠性和无序性。本文结合高性能路由器的体系结构, 介绍了UDP 协议在高性能路由器内部通信中的实现方法。 关键词 TCP 协议;UDP 协议;高端路由器;内部通信 Abstract: UDP is a transport protocol of extensive application. UDP has the character of simple nd fast transmission, However, because of it’s face of connectionless, the transmission of UDP rotocol is irresponsible and out-of-order. This paper based on the framework of igh-Performance Router, presents a design method of UDP used in inner connunication of router nd implements it.
