Graphs are models of communication networks. This paper applies symbolic combinatorial techniques in order to characterize the interplay between two parameters of a random graph, namely its density (the number of edges in the graph) and its robustness to link failures. Here, robustness means multiple connectivity by short disjoint paths: a triple (G,s,t), where G is a graph and s, t are designated vertices, is called l-robust if s and t are connected via at least two edge-disjoint paths of length at most l. We determine the expected number of ways to get from s to t via two edge-disjoint paths of length l in the classical random graph model gn.p by means of "symbolic" combinatorial methods. We then derive bounds on related threshold probabilities as functions of l and n.
