基于多优先级时延预留的接入控制机制

在网络向着区分服务和多媒体业务发展的趋势下，将时延预留思想引入具有多优先级的多媒体网络中，通过计算统计平均意义上不同优先级业务的时延门限值，提高了该多优先级多媒体网络的网络利用率，在保障了对高优先级业务服务的同时也对低优先级业务提供了良好的服务。

Multi-priority Delay Reservation Admission Control Scheme

With the development of differentiated services and multimedia services of network, a multipriority delay reservation admission control scheme is proposed. In this scheme, different delay threshold of different traffic class is statistically derived. Through computed delay threshold, the admission of different traffic was controlled so as to provide their required service. Numerical results show that either the service of high priority traffic or the service of low priority traffic is guaranteed in the new scheme. The utilization of the network is also promoted.
