RESUMO

A QoS (Quality of Service) provisioned CIOQ (Combined Input Output Queuing) switch using crossbar structure with m parallel lines per output port is proposed in this work. The packets at input buffers are transferred to the output buffers by means of mxN internal lines. Since all internal lines have the same speed as external links, no internal clock speedup is required so that the proposed structure is suited for high-speed switches. Switch models for analysis are proposed for both fixed and variable packet lengths and their performances, in terms of average packet waiting time and average queue size for both input and output buffers, are evaluated by simulation and/or analytically by means of queuing theory. The proposed switch also presents a feature that facilitates the choice of scheduler in order to satisfy the QoS of each class of service
