A clustering technique for long local computer networks

A multistage switch connection approach to improve the performance of large local computer networks is devised. The single large LAN is partitioned into smaller networks and these networks are interconnected by a Delta multistage butterfly switch. The performance of the single large network and the proposed partitioned network have been modeled and simulated using SIMSCRIPT II.5. The scheme has been applied to the token bus topology as a case study. It has been shown that the throughput of the proposed partitioned network is increased and there is a significant decrease in the average packet delay compared to the single large network. Key Words: LAN, partitioning, simulation, token bus, switch connection, Delta switch, performance evaluation, clustering techniques.
