摘要：This paper describes a new fault-tolerant routing algorithm for 3-D tori using the concept of “probability vectors”. To compute these vectors, a node determines first its faulty set, which represents the set of all its neighboring nodes that are faulty or unreachable due to faulty links. Each node then calculates a probability vector, where the lth element represents the probability that a destination node at distance l cannot be reached through a minimal path due to a faulty node or link. The probability vectors are used by all the nodes to achieve an efficient fault-tolerant routing in the network. An extensive performance evaluation conducted in this study reveals that the proposed algorithm exhibits good fault-tolerance properties in terms of the achieved percentage of reachability and routing distances
