摘要:

针对多优先级多媒体网络提出了一种采用多优先级时延预留的呼叫接入控制机制,通过对不同的优先级业务采用不同的时延门限来控制业务的接入来保证网络服务质量.仿真结果表明,多优先级时延预留机制不但较好的提供了对高优先级业务的服务率也保证了对低优先级业务的服务,同时网络利用率也相应得到了提高.

关键词: 优先级, 时延预留, 呼叫接入控制

Abstract:

An admission control scheme with multi-priority delay reservation is proposed for multi-priority multimedia network. In the scheme, different delay threshold was adopted for different priority traffic so as to guarantee network QoS. Numerical results showed that the service of both high priority traffic and low priority traffic was guaranteed by the new scheme, and moreover, the network utilization was promoted.

Key words: priority, delay reservation, call admission control
