摘　　要：提出了基于子网的E-2DMesh网络结构在存在链路故障情况下的状态转移模型。通过马尔科夫链过程建立了具有单向链路的E-2DMesh网络的可靠性模型,并分别对链路失效独立和链路失效相关条件下的网络可靠性进行了分析。运用概率分析的方法,通过组合模型计算出了较大规模的E-2DMesh网络的可靠性。通过对模型的仿真表明,链路失效相关时的网络可靠性要比链路失效独立时的网络可靠性低。A state transition model is proposed for an E-2DMesh network structure which is based on subnet under link failure exists.The Markov model of E-2DMesh network with unidirectional links is introduced and the reliability of E-2DMesh network with failure-dependent and failure-independent links is analyzed respcctively.A probability method is used to calculate the reliability of E-2DMesh network with large scale by combination model.The simulation results show that the reliability of network with failure-dependent links is less than the one with failure- independent links.
