Ca equivalent capacity CAC deal with worst case traffic in GCRA-policed ATM networks?

摘要

In order to manage modern ATM networks various methods for connection admission control (CAC) have been proposed.In addition ,usage parameter control (UPC) algorithms supervise the transmitted traffic to prevent the user from exceeding the negotiated traffic parameters.This papr addresses the question,whether the broadly accepte Euqivalent Capacity CAC algorithm cna guarantee the quality of sevice asserted to hte subscribers provided that the algorithm has only knowledge of the specified GCRA parameters used for UPC.We describe two types of worst case traffic ocnformign to hte Generic Cell Rate Algoirhtm and hsow the performance of Euqivalent Capacity CAC in various traffic scenarios.
