The motives for seeking a set of short disjoint paths in a communication network are explained. A sequentially constructed optimal set is defined. Three efficient algorithms, one that constructs an optimal set and two that construct approximations, are presented. One of the latter algorithms not only constructs a larger set of short disjoint paths than an iterated version of the standard Dijkstra algorithm, but also offers a major reduction in computation time for large networks
