摘　　要：近年的研究表明 ,无论是LAN还是WAN业务流 ,都表现出自相似业务特征。为准确评价ABR流量控制算法在真实网络中的性能 ,本文用仿真方法研究了ABR流量控制算法在自相似VBR业务环境下的动态特性。其目的在于 :为交换机设计中ABR流量控制算法的选取提供理论依据 ;通过仿真来确定算法的优缺点 ,为进一步改进算法性能提供参考。The recent research indicates that both LAN traffic and WAN traffic hav e the characteristic of self-similar.In order to exactly evaluate the performan ce of ABR flow control algorithms,we study their dynamics behavior under the envir onment of self-similar VBR traffic by means of simulation.There are two purpose s:the first is to provide theoretic evidences for selecting ABR flow control alg orithm during the switch design,and the second is to offer some references to im prove these algorithms by giving their advantages and shortcomings.
