Abstract : We assume that we have an (n,m)graph with n vertices and m edges, representing a communications network with each vertex representing a processor and each edge a communications link. We have begun our work by concentrating on the cutting number/pairconnected reliability measure and have initially assumed that each vertex will always remain operable and that each edge has the same probability of failure q. Thus, p=1q is the probability that any given edge is operable. A standard measure of system reliability is the probability that the graph remains connected. This is denoted by P(G;q), and the probability that a specified pair s and t of vertices is connected is denoted by Ps,t(G;q). The cutting number/pairconnected measure refines the connectivity reliability measure by considering the varying effects of different cutsets.
