在考察了接入 IP业务时四种 ATM ABR流量控制算法之后 ,对网中存在 VBR背景流的情况下的性能进行了分析研究 ,发现通过计算机仿真 ,虽然计算 ACR的方法各异 ,四种算法均能够使网络提供持续、有效的服务
After examining the four ATM ABR flow control algorithms for accessing IP services, the performance of the network in the presence of VBR background flow is analyzed and studied. It is found that although the methods for calculating ACR are different through computer simulation, the four algorithms All can make the network provide continuous and effective service
