摘要
本文阐述了传统ＩＰ路由协议存在的问题。回顾了ＱｏＳ路由技术在电路交换网络，ＡＴＭ 网络和ＩＰ网络中的演进与应用。论述了业务工程在Ｉｎｔｅｒｎｅｔ 中的基本功能，以及与之相关的约束路由和ＭＰＬＳ技术。
This paper first expounds the problem existed with classical IP routing protocol. Then the evolution of QoS routing technologies in circuit switched network, ATM network and IP network is reviewed. After that, the basic functions of traffic engineering in the contemporary Internet are described. Finally, the relationship between traffic engineering over multi protocol label switching (MPLS) and constraint based routing is discussed.
