用数学法研究总线网性能

Analyzing performance of bus network by mathematical way

网络中的数据流是不确定的,数据包的到达时间、长度和处理时间都是随机变量。通过数学方法研究总线网的性能就是在一定的假设基础上,计算出总线网的参数之间的数学关系,比如吞吐量与负载之间的关系、延迟随负载的变化情况等,其分析结果可以为计算机模拟提供理论支持,对于网络设计具有重要作用。

Data stream of network is random. Arrival time, length and processing time of data packet are random variable. The study of performance of bus network by mathematical way means working out mathematical relation among parameters of bus network based on hypothesis, for instance, the relation between throughput and load, the varying thing of lag following load and so on. The result derived from the analysis offers a theoretical support for computer's imitation and presents importance for network design.
