Abstract

With increasing probability of failure and reliability concerns for interconnection networks, fault-tolerance is quickly becoming an integral part of such systems. It is therefore critical to provide an efficient fault-tolerant mechanism to keep the system running, even in the presence of faults. In this paper a distributed fault-tolerant routing methodology for mesh networks is proposed which supports a dynamic fault model. Unlike most previous methods that support a dynamic fault model, the presented method is able to tolerate any number of faults with any shapes of fault regions without disabling healthy nodes. The performance of the method is extensively evaluated, and the results show that our proposed method is valid for mesh topology, which has graceful performance degradation and allows the network to remain fully operational facing with the failures.
二维网格中的动态容错虫洞路由
随着互连网络故障概率的增加和对可靠性的关注,容错正迅速成为这类系统不可或缺的一部分。因此,提供有效的容错机制以保持系统运行是至关重要的,即使在存在故障的情况下也是如此。本文提出了一种支持动态故障模型的网状网络分布式容错路由方法。与以前大多数支持动态故障模型的方法不同,本文提出的方法能够容忍任意数量的故障和任意形状的故障区域,而不会禁用健康节点。对该方法的性能进行了广泛的评估,结果表明该方法对网状拓扑是有效的,该方法具有良好的性能退化,并允许网络在面对故障时保持完全运行。
