Performance evaluation of the multiple output queueing switch under different traffic patterns

Performance evaluation of the MOQ switch recently proposed by us is discussed in this paper. In the MOQ switch both the switch fabric and buffers can operate at the same speed as input and output ports. This solution does not need any speedup in the switch fabric as well as any matching algorithms between inputs and outputs. The description and the first evaluation were presented earlier. In this paper new performance measures for the proposed MOQ switch are evaluated. The simulation studies have been carried out for switches of capacity 4times4, 8times8, 16times16 and 32times32, and under different traffic patterns. The simulations results are also compared with OQ switches and VOQ switches of the same sizes and under different scheduling algorithms: iSLIP, PIM, iRRM, MMRRS, HRRM
