具有失效结点2D-Torus网络可靠性研究

Reliability analysis of 2D-TORUS with failure node

结合2D-Torus网络的特点,以3×3Torus为例采用markov过程建立结点失效独立和结点失效相关条件下的网络可靠性模型.通过建立markov状态空间图并进行求解得出可靠性模型的数学表达式,计算出网络的可靠度.通过对模型的仿真表明:网络规模越大,可靠性越低;结点失效相关时的网络可靠性要比结点失效独立时的网络可靠性低.

With the peculiarity of 2D-Torus Network, the Markov model of 2D-Torus is introduced through the study of Torus.Getting the math expressions by Establish and derivation the markov state spaces. Couting out the reliability of 2D-Torus Network.The simulation results show that with the complex of the network, the reliability of network is more and more lower; the reliability of network with failure-dependent nodes is less than the one with failure independent nodes.
