FAULT-TOLERANT ROUTING IN UNIQUE-PATH MULTISTAGE OMEGA NETWORK

Abstract

In this paper, two new near one-pass packet-routing schemes are proposed to tolerate all single faults among the switching boxes or the connecting links respectively in a unique-path multistage Omega network. Working in an undirected network, our results can compete with the two-pass routing scheme, which works in a directed network, proposed by Varma.
