11/091731

Inventors:

Jack C. Wybenga - Plano TX, US
Patricia K. Sturm - Marion IA, US
Mark Lang - Plano TX, US

Assignee:

Samsung Electronics Co., Ltd. - Suwon-si

International Classification:

G06F 15/16

US Classification:

709201, 709227

Abstract:

Samsung Electronics Co., Ltd. - Suwon-si

International Classification:

H04L 12/28
H04L 12/56

US Classification:

370389

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.

International Classification:

H04L012/54

US Classification:

370428000

Abstract:

A router for interconnecting external devices coupled to the router. The router comprises a switch fabric and a plurality of routing nodes coupled to the switch fabric. Each of the routing nodes exchanges data packets with the external devices via network interface ports and with other routing nodes via the switch fabric. A first routing node comprises an inbound network processor capable of receiving incoming data packets from a network interface port; an outbound network processor capable of transmitting data packets to the network interface port; and a shared memory for storing forwarding table information used by the inbound and outbound network processors. The shared memory comprises an inbound upper bank capable of storing forwarding table information accessed by the inbound network processor and an inbound lower bank capable of storing forwarding table information accessed by the inbound network processor.
