EN Different Clos-network architectures in terms of buffer allocation were proposed in papers: SSS (Space-Space-Space), MMM (Memory-Memory-Memory), MSM (Memory-Space-Memory), and SMM (Space-Memory-Memory). The most investigated architectures are SSS and MSM. This paper deals with the packet-dispatching scheme based on static connection patterns and internal backpressure signals for the SMM Clos-network switches, where the second and third stages are made of crosspoint queued (CQ) switches. The proposed dispatching scheme is called SDIB (Static Dispatching with Internal Backpressure). Simulation results show that proposed algorithm delivers very good performance in terms of throughput, cell delay and input buffers size, under different traffic distribution patterns, for both Bernoulli and bursty traffic.
