摘要:

边界网关协议BGP(border gateway pr otocol)是Internet上用于自治系统之间交换路由信息的动态路由协议.介绍了在清华大学研制的国产高性能路由器中分布式路由协议BGP-4的具体实现.为了实现这一复杂的动态协议, 提出基于事件驱动的设计和实现方法.事件驱动机制能够精确地反映网络报文交换行为的实现机制,因而很适合Internet高层协议的实现.该方法也可以用于实现其他的Internet高层协议.

Design and Implementation of Border Gateway Protocol BGP-4 Based on Event-Driven Programming

XU Ke,WU Jian-ping,FAN Xiao-bo

Abstract:

Border Gateway Protocol (BGP) is a distribute d dynamic routing protocol for exchanging routing information among autonomous s ystems. In this paper, the implementation of distributed routing protocol BGP-4 in high performance router developed by Tsinghua University is presented. A met hod based on event-driven programming is presented to implement the complicated protocol. Event-driven programming can reflect the real situation of networks, so it is suitable for the network programming. This method can also be used to implement other higher layer protocols of Internet.

Key words: high-performance router routing proto col BGP (border gateway protocol) event-driven programming
