The Shortest Virtual Routing Policy Based on VP Subnet in ATM Networks

应用信号流图法，提出了一种新颖的差分式连续时间电流模式ＣＭＯＳ跨导—电容双二阶滤波器，该滤波器仅使用最少量的差分式ＯＴＡ和电容并且能有效地消除偶次谐波失真、具有较低的特征参数灵敏度等优点；面向实际电路完成了ＭＯＳ管级的计算机仿真，仿真结果表明所提出的电路方案正确有效，适于全集成。

This paper uses the experience of routing mode in packet-switched networks for refernce,according to ATM network characteristics,presents the shortest routing policy for virtual channels (VC) based on virtual paths (VP) subnets,discusses its effectiveness by simulate with computer and compare it with LBA(Least Busy Alternative)policy The result is that in the case of small and large current loads,both routing policy effectiveness is approximatively the same,but in the case of middle,the policy in this paper is prior to LBA stratage.
