Abstract

Routing algorithms for general topology broadband networks should make sensible tradeoffs between optimality and complexity. An algorithm based on the shortest path algorithm and competitive analysis recently proposed by us was found to perform very well for general traffic patterns at any network loads when the Quality of Service (QoS) constraints are not considered.. In this paper, we show that the proposed algorithm also has very good performance while satisfying stringent delay bound requirements. The proposed algorithm and several other existing relatively efficient routing algorithms for general topology networks are fairly evaluated and compared through simulations by using call rejection probability, network throughput and fairness measures for the first time.
