Throughput and packet loss in deflection routingmultichannel-metropolitan area networks

摘要

A comparison is made between the performance of two differencenetwork architectures to implement multichannel-metropolitan areanetworks (M-MANs). Both networks, the bidirectional Manhattan streetnetwork (BMSN) and the shuffle net (SN), are assumed with connectivitydegree four. Performance under investigation includes throughput,average delay and packet loss. In the authors' model, user's attachmentsto network nodes are equipped with input and output buffers andperformance depends on buffer sizes. The network reliability is takeninto account and the behavior of both networks under given link failureoccurrences is noted. The comparison is based on simulation results.Pros and cons of the two M-MAN architectures are pointed out in thediscussion of the results
