摘　　要：star互连网络作为大规模处理器系统网络模型的重要候选之一,其可靠性问题一直为人们所关注。在链路可靠概率模型的基础上,分别采用不同的分析方法对star网络的可靠性进行了分析,建立了相应的可靠性模型。这些可靠性模型指出了链路可靠性与网络可靠性之间的约束关系。模拟实验结果表明,在现有大规模集成电路技术的条件下,这些可靠性分析方法都是可行的,而且star网络的可靠性可以控制在一个理想的范围内。Reliability problems on star interconnection network regarded as one of important candidates of network models in large-scale processor systems have been being concerned by people. Under probability model based on link reliability, reliability of star network was analyzed by different analysis methods, and reliability models that correspond to those different methods were set up. The constraint relation between link reliability and network reliability was indicated by above reliability models. The results of simulation experiments show that under existing massive integrated circuit technology,these analysis methods on reliability are all feasible and reliability of star network can be controlled within a ideal scale.
