摘要:

针对具有故障部件的STAR互联网络的可靠性问题,在有条件的容错模型和概率模型的基础上,提出了一种新的评估STAR网络可靠性的方法。该方法通过网络的二连通率来进行评估。首先提出了一个自适应的容错并行路由算法,通过该算法的多次执行,得到用于计算网络二连通率的相关条件参数,在此基础上建立了用于推断网络二连通率的贝叶斯网模型。然后通过基于贝叶斯网的概率推理,可得到反映网络可靠性的网络二连通率。研究结果表明,该方法拓展了人们在网络可靠性评价方面的视野,具有一定的理论和实际意义。

Abstract:

To solve reliability problems on STAR interconnection networks with fault parts, under the conditional faulttolerant model and the probabilistic model, a new method used for assessing reliability of STAR networks is proposed. The reliability of networks is evaluated by twoconnection probability of networks in the method. A adaptive faulttolerant parallel routing algorithm is proposed firstly, and relational condition parameters used for computing twoconnection probability of networks are derived by its performance at many times, furthermore a Bayesian networks model for deducing twoconnection probability of networks is also established. The twoconnection probability of networks used for reflecting reliability of networks is derived by probabilistic inference based on this Bayesian networks. The results show that this method broadens peoples horizons toward the evaluation for reliability of networks, so it has certainly theoretical and practical significance.
