Abstract
A router for transferring data packets between external devices. The router comprises: 1) a switch fabric; and 2) R routing nodes coupled to the switch fabric. Each routing node exchanges data packets with the external devices and with other routing nodes via the switch fabric. A first routing node comprises: i) an inbound network processor comprising a first plurality of microengines capable of forwarding incoming data packets from external ports to the switch fabric; ii) an outbound network processor comprising a second plurality of microengines capable of forwarding outgoing data packets from the switch fabric to the external ports; and iii) an asynchronous variables circuit for controlling access of the inbound and outbound network processors to at least one of i) a shared resource and ii) a shared variable in the router.
