弹性分组环中的队列长度分析

Queue Length Analysis in Resilient Packet Ring

弹性分组环是城域网发展的重要方向。为了实现基于优先级区分的业务服务质量,弹性分组环采用基于优先级区分的队列以及转发机制。利用M/G/1/K排队模型分析弹性分组环中各类业务缓存中的分组队列长度。与M/G/1排队模型相比,该模型可以获得更准确的结果,实用价值较高。

Resilient Packet Ring（RPR） is one of the important development orientation of LANs. In order to guarantee the QoS of traffic based on priority division, RPR adopts the multiple-channel and multiple-queue to differentiate the traffic with priorities. This paper uses M/G/1/K model to analyze the length of RPR queue systems. Comparing with M/G/1 model, the model can get exacter result and is more valuable in application.
