  • Patent number: 8761180
    Abstract: A router for switching data packets from a source to a destination in a network in which the router includes a distributed memory. The distributed memory includes two or more memory banks. Each memory bank is used for storing uniform portions of a data packet received from a source and linking information for each data packet to allow for the extraction of the uniform portions of a data packet from distributed locations in memory in proper order after a routing determination has been made by the router.

  • Patent number: 8483222
    Abstract: The invention is directed to techniques for supporting multi-link protocols within a computer network. In one embodiment, a method includes receiving a set of data blocks from a plurality of links in one or more interface cards according to a multi-link protocol and sending the data blocks to a multi-link service card for sequencing. The data blocks may then be sent to the one or more interface cards for communication to a destination device over a computer network. Implementing a multi-link service card may allow a network device, such as a router, to support multi-link protocols.

  • Publication number: 20120263178
    Abstract: A network device constructs a notification corresponding to a received multicast data unit, where the notification includes administrative data associated with the multicast data unit that does not include a payload of the multicast data unit. The network device replicates the notification at at least three different processing elements at different locations in a processing path of the network device to produce multiple replicated data items and produces a copy of the multicast data unit for each of replicated notifications. The network device forwards each copy of the multicast data unit towards a multicast destination.

  • Patent number: 8190699
    Abstract: In a particular embodiment, a multi-path bridge circuit includes a backplane input/output (I/O) interface to couple to a local backplane having at least one communication path to a processing node and includes at least one host interface adapted to couple to a corresponding at least one processor. The multi-path bridge circuit further includes logic adapted to identify two or more communication paths through the backplane interface to a destination memory, to divide a data block stored at a source memory into data block portions, and to transfer the data block portions in parallel from the source memory to the destination node via the identified two or more communication paths.

  • Patent number: 7664873
    Abstract: Samples from an addressed data forwarding devices, such as a router, are associated with path-centric information. Information from the samples is used to update corresponding path-centric traffic information, such as flow information for example. The aggregated path-centric traffic information can then be used by traffic analysis operations.

  • Patent number: 7289503
    Abstract: A network device includes an interface and packet processing logic. The interface receives a multicast packet. The packet processing logic determines identifier data corresponding to the received multicast packet and replicates the identifier data to multiple outgoing packet forward engines at a first point in a processing path. The packet processing logic further replicates the identifier data to multiple data streams at a second point in the processing path and replicates the identifier data to multiple logical interfaces in the same stream at a third point in the processing path.

  • Publication number: 20070147257
    Abstract: A method and apparatus for in-line processing a data packet while routing the packet through a router in a system transmitting data packets between a source and a destination over a network including the router. The method includes receiving the data packet and pre-processing layer header data for the data packet as the data packet is received and prior to transferring any portion of the data packet to packet memory. The data packet is thereafter stored in the packet memory. A routing through the router is determined including a next hop index describing the next connection in the network. The data packet is retrieved from the packet memory and a new layer header for the data packet is constructed from the next hop index while the data packet is being retrieved from memory. The new layer header is coupled to the data packet prior to transfer from the router.

  • Publication number: 20070141436
    Abstract: Fabricating roll-good fuel cell material involves laminating first and second bonding material webs having spaced apart windows to first and second surfaces of a fuel cell membrane web. First and second active regions of the membrane web are positioned within the respective bonding material windows. Third and fourth gasket material webs having spaced apart windows are respectively laminated to the bonding material on the first and second membrane web surfaces. The bonding material windows align with the respective gasket material windows so that at least some of the bonding material extends within the respective gasket material windows. Fluid transport layer (FTL) material portions cut from fifth and sixth FTL material webs are laminated to the respective first and second active regions. The FTL material portions are positioned within respective gasket material windows and contact the bonding material extending within the respective gasket material windows.

  • Publication number: 20070053318
    Abstract: A subscriber controlled registration protocol, a subscriber monitors a congestion indicator signal broadcasted by a base station with which it desires to register. If the congestion indicator signal indicates that the base station is operating in a congested state, the mobile station selects another base station in the system. Otherwise, it attempts to register with the first selected base station.
