Abstract
A network switch for network communications includes an embedded programmable state machine to monitor data flows through the switch. The programmable state machine is configured to retain selectable states of selectable data packet fields. Programmable switch logic operative with the programmable state machine is configured to output one or more potential actions to be taken based on a selectable computation of detected selectable states. The programmable state machine can be implemented with either table lookups or flexible logic.
