Cooperative load balancing algorithm in multiple bottleneck networks

Abstract

In this paper we validate the recent introduced cooperative load balancing algorithm ([6]) in a multiple bottleneck scenario. The controller at each router (server or switch) regulates the rates of the heterogeneous sources leveraging on the cooperation of neighboring bottlenecks. The proposed approach guarantees good performance in terms of link utilization, packet loss and fairness. Additionally it is guaranteed queue balancing without requiring rerouting or hop by hop operation differently from the existing approaches. A validation is carried out by a discrete packet experiment simulator in a realistic multi-bottleneck scenario to demonstrate the effectiveness of the key idea of the paper.
