To verify the analysis results, a simulation tool for network reliablity-NRS is designed and implemented. The simulator can be used to model reliability of several network topologies referred above and the reliability of layer network.

• 为验证解析结果的正确性,设计并实现了针对网络可靠性的模拟器NRS(Network Reliability Simulator),它可以对上述多种网络的可靠性进行模拟,而且可以对以典型网络拓扑结构为骨干网的层次网络进行仿真。
