Load balanced Birkhoff-von Neumann switch with output congestion detection

Abstract

The development of new services and increase of the number of users lead to the Internet traffic growth. In order to efficiently keep up with the Internet growth, packet switches must improve their performances in order to support increased amount of traffic at greater speeds. One of the most popular packet switch solutions are Load-Balanced Birkhoff-von Neumann (LB-BvN) packet switches, because of their very simple hardware implementation. Packet switches should also support fair service of user flows during the temporary congestion in the network. In this paper, we propose a novel switch based on the LB-BvN architecture that achieves better performance in terms of fair service compared to existing LB-BvN switches. The proposed switch is compared to other LB-BvN based switches, in terms of average packet delay and fair service.
