Abstract

Multistage Interconnection Networks are used in parallel computer applications as well as in new, high performance packet switch architecture for communication systems. In these networks the presence of unbalanced traffic loads creates significant performance problems. The main goal of this paper is to propose: (a) a flow control scheme, which permits the characterization of the traffic distribution, and (b) switching strategies, at the packet level, for controlling this performance degradation. We also present a switch model, in order to support the suggested solutions. The proposed solutions can be implemented with minimal additional logic in the switch design. Simulation results are presented to test the effectiveness of the proposed approach.
