International Classification:
G06F009/46
US Classification:
718100000
Abstract:
An accelerated operating system can increase the data processing throughput of a data processor executing an application according to a sequential programming model. An application running on a main data processor is interfaced to an operating system which has been accelerated by distributing at least some of the operating system among a plurality of subordinate data processors which provide data processing support for the application running on the main data processor. The subordinate data processors can thus also provide operating system support for the application running on the main data processor. This decreases the processing burden on the main data processor, thereby increasing the main data processor's data processing throughput while executing the application.

US Classification:
37039531, 370428
Abstract:
A routing table search circuit comprising a forwarding table containing forwarding table entries, each forwarding table entry comprising a destination address, and a content addressable memory (CAM) comprising a CAM lookup table, the CAM receiving a search key and outputting a CAM search result corresponding to the search key from the CAM lookup table. The search key comprises at least: i) a packet type field associated with the first received address and ii) an address field containing a most significant bits portion of the first received address. The routing table search circuit also comprises M pipelined memory stages for storing a trie table that translates the first received address into the first destination address. The M pipelined memory stages are searched using the CAM search result and a remaining bits portion of the first received address. Each of the M pipelined memory stages outputs a stage search result.

Abstract:
A router for interconnecting external devices comprising: 1) a switch fabric; and 2) R routing nodes coupled to the switch fabric. Each of the R 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: i) an inbound network processor for receiving incoming data packets from a network interface port; ii) an outbound network processor for transmitting data packets to the network interface port; and iii) a shared memory accessible by the inbound and outbound network processors for storing a current trie tree search table and a current vector table used to index into the trie tree search table. A control plane processor generates an updated vector table to replace the current vector table and notifies the inbound and outbound network processors that the updated vector table is available.

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 transmits data packets to, and receives data packets from, the external devices and other routing nodes via the switch fabric. The switch fabric detects that the output bandwidth of a first output of the switch fabric has been exceeded and, in response to the detection, attempts to slow the input ports and drops lower priority packets if necessary. The routing nodes give precedence to routing higher priority packets.

International Classification:
H04L 12/56
US Classification:

Abstract:
A router for transmitting data packets to and receiving data packets from N interfacing peripheral devices. The router comprises a plurality of processors that exchange data packets with each other over a common bus. A source processor transmits a data packet to a destination processor by storing the data packet in an output queue associated with the source processor and transmits an interrupt message to the destination processor. The destination processor, in response to the interrupt message, reads the data packet from the output queue.
