Abstract

The SCOQ switch is a Batcher-banyan based high performance fast packet switch with shared concentration and output queueing, with a maximum of L(<N, the switch size) packets delivered to each output buffer in a slot [Chen and Mark, 1994]. The present paper considers the performance of the SCOQ switch under nonuniform traffic loadings. Based on the analysis of nonuniform traffic patterns, a buffer management congestion control scheme is proposed with the K=N/L output ports of each of the L switching modules sharing their buffering capacity. Numerical results show that the buffer management scheme is quite effective
