Abstract
A QoS provisioned CIOQ ATM switch with m internal links is proposed in this paper. In the proposed switch the incoming cells at each input port are discriminated into service classes. For each service class, at each input port, a single buffer is provided whereas each output port needs m buffers, where m is the number of internal links (or channels) that connect each input port to each output port. The proposed switch uses physical internal links instead of time division, thus no speedup is required. The results of simulation of proposed switch using simple priority schedulers show that for m≥3 the number of cell waiting at input queue is small, less than 0,1 cells in average, independent of service classes. The proposed switch has also the feature that facilitates the choice of scheduler in order to satisfy the QoS of each class of service.
