Abstract

In this paper we present an evaluation of communication in the network of a faulty hypercube using an approximate analytical model and a detailed simulation model. We asume the hypercube has a deterministic routing strategy. Consequently, we are able to use simple models to derive the traffic on each link. Additionally, we develop a theory with which we find the message delay not only in packet-switched hypercube networks, but in the more current circuit-switched networks as well. Thus we can examine the degradation from ideal communication performance due to different fault patterns and different reroute strategies we may use to compensate for faults. We next describe a program, EASY, which implements our approximate analysis along with simulation for detailed evaluation of message communication. We include a comparison of our theoretical evaluation with simulation. We also include a brief comparison of reroute techniques for faulty hypercubes.

一种评估故障超多维数据集中消息通信的方法
本文采用近似解析模型和详细仿真模型对故障超立方体网络中的通信进行了评估。我们假设超立方体具有确定性路由策略。因此,我们能够使用简单的模型来推导每个链路上的流量。此外,我们发展了一个理论,我们发现消息延迟不仅在分组交换的超立方体网络中,而且在更当前的电路交换网络中也是如此。因此,我们可以检查由于不同的故障模式和我们可能用于补偿故障的不同重路由策略而导致的理想通信性能的退化。接下来,我们描述了一个程序,EASY,它实现了我们的近似分析和仿真,以详细评估消息通信。我们将我们的理论评估与模拟进行了比较。我们还简要比较了故障超多维数据集的重路由技术。
