SCOQ: a fast packet switch with shared concentration and output queueing
Dabei Chen, J.W. Mark · IEEE/ACM Transactions on Networking · 1993
A space-division, nonblocking packet switch with data concentration and output buffering is proposed. The performance of the switch is evaluated with respect to packet loss probability, the first and second moments of the equilibrium queue length and waiting time, throughput, and buffer overflow probability. Numerical results indicate that the switch exhibits very good delay-throughput performance over a wide range of input traffic. The switch compares favorably with some previously proposed switches in terms of fewer basic building elements used to attain the same degree of output buffering.>
