<title>Performance analysis of lightwave packet communication networks</title>

Abstract

To interconnect multiple user stations in Local Area Networks (LANs) and/or Metropolitan Area Networks (MANs) environment a ShuffleNet multichannel multihop Lightwave Packet Communication Network concept has been recently proposed. The Wavelength Division Multiplexing (WDM) concept is applied to provide a total network capacity in the order of hundreds or thousands of Giga bits/second (Gbps) with each user station assigned a peak limited capacity of 1 Gbps. The performance analysis of a ShuffleNet multihop lightwave network under uniform and nonuniform input traffic load patterns are studied and the corresponding simulation results are presented in this paper. The input traffic load to the network consists of uniform as well as nonuniform traffic patterns. . A fewer ShuffleNet network topologies are simulated and A Fixed Routing algorithm as well as an Adaptive Routing algorithm are applied for routing the uniform and nonuniform input packet traffic requirements. The resultant average network throughput and packet delay performance characteristic curves are plotted and analyzed. The corresponding simulation results indicate that the adaptive routing algorithm provides better average network throughput and packet delay performance characteristics when compared to fixed routing algorithm.
