For sure, in a switch theere is dedicated hardware in charge of doing the packet forwarding, but the scheduling is a typical software/firmware task and only boxes which need to do WFQ at 100Mbit/s or so really need to put the scheduler on silicon. then of course you can always claim "nobody has ever been fired for buying IBM..." cheers luigi -----------------------------------+------------------------------------- Luigi RIZZO, luigi@iet.unipi.it .
