Abstract
A physically realizable one terabit or more ATM packet switch that has a large number of input interfaces connected to a single stage switching fabric which is in turn connected to a number of output modules, generally according to the growable packet switch architecture. This ATM packet switch is different from other growable packet switches in that it has a single stage switch fabric controlled by an out-of-band controller, yet it has significantly reduced complexity with respect to comparably sized electronic crossbar switches or their isomorphs. The out-of-band controller has multiple priority levels in order to provide high priority users with a near certainty that their packets will be successfully routed, while delivering an acceptably low packet or cell loss probability to users at the lowest priority level.
