Abstract: Reliability problems on star interconnection network regarded as one of important candidates of network models in largcscale 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.
