DYNAMIC RESOURCE CONTROL OF THE VIRTUAL PATH IN ATM NETWORKS

Virtual path concept has several valuable features to re construct an economical and efficient ATM network.The most important effect of VPs is to afford transmission efficiently through the dynamic control of VPs resource including buffer and bandwidth.This paper described the problem of dynamic resource control of VP in ATM networks.Based on a discrete event dynamic model of resource control of VP in ATM networks,the optimal control law of resource allocation of VP in ATM networks with the method of dynamic programming was presented.The results of the theorem proof and simulation show that the dynamic control is more efficient to reduce the calls block rate comparing with the static allocation.
