Summary :

We propose knockout ATM switches with two speedup factors under non-uniform traffic with variable hot-spot ports in order to handle flexibly when the number and port of hot-spot change. The proposed models have a function that the maximum cell transmission number called a speedup factor L₂ is set to be large when the arrival cells are more than L₁. By using this function, it is useful to decrease the cell loss probability of hot-spot ports. First, we propose a knockout ATM switch with two speedup factor in order to reduce the number of accesses from a concentrator to a parallel buffer as a proposed model 1. Moreover, we propose a shared knockout ATM switch in order to decrease the switch elements as a proposed model 2. We evaluate the cell loss probability by means of computer simulations and numerical calculations. As a result, we show that the proposed model 2 satisfy the reqirement of the cell loss probability due to contention at outoput of a batcher network with decreasing the hardware.
