The knockout switch is a switch fabric proposed for fast packet switching. Under certain non-uniform traffic patterns (i.e. a 'hot spot contention') the switch exhibits an increase in the packet loss rate. A rearrangeable switch fabric based on knockout switch concepts is proposed which, on the occurrence of 'hot spot' traffic, reconfigures itself to guarantee a very low packet loss rate. The new switch architecture is presented, and parameters affecting performance are analysed. An implementation based on dynamically reconfigurable VLSI components is proposed.

Abstract
The knockout switch is a switch fabric proposed for fast packet switching. Under certain non-uniform traffic patterns (i.e. a 'hot spot contention') the switch exhibits an increase in the packet loss rate. A rearrangeable switch fabric based on knockout switch concepts is proposed which, on the occurrence of 'hot spot' traffic, reconfigures itself to guarantee a very low packet loss rate. The new switch architecture is presented, and parameters affecting performance are analysed. An implementation based on dynamically reconfigurable VLSI components is proposed.File in questo prodotto:
