摘要
提出了一个ATM交换机的计算机仿真系统,用于网络交换系统的教学、科研与设计。系统平台由主机和HUB*组成,基于Crossbar的8×8标准点数构造,对OPNET中几种最大匹配仿真算法(PIM、iSLIP、FIRM)进行了实际比较;通过对仿真结果的平均调度时延、负载的分析,找出算法的瓶颈,设计出新的SOS算法。实测证明,采用VOQ技术可将原56.8%吞吐量提高到100%,实现了计算机高效仿真交换的目的。
A computer simulation system of ATM switch, which is used in teaching, science research and design of network switching system, is brought forward. The system platform consists of host and HUB＊, it is constructed based on Crossbar standard point number of 8×8, and several maximal matching simulation algorithms such as PIM, iSLIP and FIRM in OPNET are practically compared. Through analyzing the average scheduling delay and load of simulation results, the bottleneck of the algorithm is found and a new SOS algorithm is designed. The test shows that the throughput can be improved from 56.8 percent up to 100 percent by using VOQ technology and the aim of efficient computer simulation switch is realized.
