Performance of CTC(N) Switch under Various Traffic Models

摘要

In previous papers, we introduced and analyzed an innovative agile crossbar switch architecture called contention-tolerant crossbar, denoted as CTC(N), only under Bernoulli i.i.d. uniform traffic model. The CTC(N) switch achieves about 63% throughput without any internal speedup and 100% throughput with either speedup of 2 or 2 CTC(N) fabrics operating in parallel. In this paper we evaluate the throughput and mean cell delay of CTC(N) switch under four different traffic models. By simulation, quantitative results are presented, evaluated and compared to traditional crossbar switches.
