### Abstract

This paper describes a new fault-tolerant routing algorithm for the hypercube, using the concept of probability vectors. Each node calculates a probability vector whose kth element represents the probability that a destination node at distance k cannot be minimally reached due to a faulty node or link. A performance comparison with the recently-proposed safety vectors algorithm, through extensive simulation, shows that the new algorithm exhibits superior performance in terms of routing distances and percentage of reachability.
