Recently, parallel processing systems have been studied very actively, and many topologies have been proposed. A hypercube is one of the most popular topologies for interconnection networks. In this paper, we propose two new fault-tolerant routing algorithms for hypercubes based on approximate directed routable probabilities. The probability represents ability of routing to any node at a specific distance and also taking account of from which direction the message was received. Each node chooses one of its neighbor nodes to send a message by comparing the approximate directed routable probabilities. We also conducted a computer experiment to verify the effectiveness of our algorithms.
