多级优先权非对称性环形网络性能分析与评价

PERFORMANCE ANALYSIS AND EVALUATION OF ASYMMETRIC MULTI─PRIORITIZED RING─SHAPE NETWORKS

在现代与未来的计算机网络中，将越来越广泛地使用多路信息流环形网络。本文概述了这类网络的多级优先权协议，对此进行了排队分析，建立了反映网络性能的数学模型，得出了非对称性环形网络各站具有不同优先权各路信息流的平均等待延迟的估算结果。另外，还进行了数字分析，阐明了信息流分布、吞吐量、优先权、重负载、轻负载及其位置对平均等待时延的影响。

In modern and future computer network, the ring-shape network of multi-way message flows will be more and more widely used. This paper summarizes the multi-level priolitized protocols of this type network,carries out the queueing analysis,set up the mathematics models that reflect network performance, obtains the approximate results of mean waiting delay for asymmetric ring network with different prioritized message flows of every station. In addition, it still carries out numerical analysis, expounds the influence of the message flow distribution, throughput, priority, heavy and light load, and their position to mean waiting delay.
