Abstract

Given a graph G representing a network topology, and a collection T={(s1,t1)...(sk,tk)} of pairs of vertices in G representing connection request, the maximum edge-disjoint paths problem is an NP-hard problem which consists in determining the maximum number of pairs in T that can be routed in G by mutually edge-disjoint si-ti paths. We propose an Ant Colony Optimization (aco) algorithm to solve this problem. aco algorithms are inspired by the foraging behavior of real ants, whose distributed nature makes them suitable for the application in network environments. Our current version is aimed for the application in static graphs. In comparison to a multi-start greedy approach, our algorithm has advantages especially when speed is an issue.
