摘要: ABR业务是ATM中新定义的一种业务类型,它主要面向数据传输服务,采用基于速率的端到端的拥塞控制机制。TCP是Internet所采用的主要数据传输协议,采用基于窗口的拥塞控制机制。文中主要讨了TCP与ABR业务所采用的两种不同的拥塞控制机制,分析了基于ANR的TCP协议所呈现的一些特点以及ATM交换机缓存的大小对TCP性能的影响。

Abstract: ABR is a new service in ATM(Asynchronous Transfer Mode)network, it adopts rate-based congestion control mechanism and is mainly used for data transmission. TCP (Transmission Control Protocol) is the data transmission protocol of Internet and uses window-based congestion control mechanism.This paper discusses the two differeni congestion control methods adopted by TCP and ABR, analysises the characters of TCP over ABR and the influence of ATM buffer to TCP performance.
