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 having a first plurality of microengines that forward incoming data packets from external ports to the switch fabric; ii) an outbound network processor having a second plurality of microengines that forward outgoing data packets from the switch fabric to the external ports; and iii) a plurality of registers for transferring messages between the first and second plurality of microengines. The registers may be 32-bit mailboxes for transferring short messages or 2 Kbyte FIFO buffers for transferring one or more large data packets.
