At very high aggregate bandwidths, output queueing is impractical because of insufficient memory bandwidth. This problem is getting worse: memory bandwidth is improving slowly, whereas the demand for network bandwidth continues to grow exponentially. The difficulty is that outputqueued switches require memories that run at a speedup of N, where N is equal to the number of switch ports. This paper addresses the following question: Is it possible for a switch toexactly match outputqueueing with a… CONTINUE READING
