  • Publication number: 20120155485
    Abstract: A method for networked communications includes receiving, on an inbound port, a frame to be forwarded, mapping the received frame to a flooding domain, determining an inbound port through which a frame is received, wherein the plurality of ports includes the inbound port, determining a destination address of the received frame, and determining one or more of the plurality of ports through which the received frame is to be forwarded. If the line card contains a port that is part of the flooding domain, the method includes populating a forwarding table associated with the line card with information regarding the received frame and information regarding the flooding domain. If the line card contains no ports that are part of the flooding domain, the method includes populating no forwarding tables associated with the line card with information regarding the received frame and information regarding the flooding domain.

  • Publication number: 20120147743
    Abstract: A method for networked communications includes determining a group identifier associated with a received request for multicast data, determining an available upstream bandwidth and an available downstream bandwidth, adding an entry for the identified group into a multicast forwarding table, allocating bandwidth from the available upstream bandwidth and available downstream bandwidth, the allocated bandwidth corresponding to bandwidth required by the requested multicast data, and forwarding the received request to an upstream network destination. The method includes, if no response is received in response to the received request within a designated timeout period, removing the entry for the identified group in the multicast forwarding table, and restoring the allocated bandwidth to the available upstream bandwidth and available downstream bandwidth.

  • Publication number: 20110249673
    Abstract: A network processing unit includes a first table, a forwarding table, and a processor. The first table includes a first entry for a network, including a network aging, which includes the network processing unit. The forwarding table includes a second entry associated with a network entity which includes an indication of whether network traffic associated with the entity has been encountered in the current or previous network aging period. The processor is configured to receive an indication from a hardware timer that a hardware aging cycle has ended, and then determine whether the network aging period has ended. If so, the processor is configured to determine for a first network entity in the forwarding table whether traffic associated with the entity has been encountered in the current or previous network aging period. If not, then the processor is configured to remove the given first network entity from the forwarding table.

  • Publication number: 20110249676
    Abstract: A method for forwarding a packet may include generating, by a first hash function module, a first hash value based on data included within the packet. The method may also include generating, by a second hash function module, a second hash value based on data included within the packet. The method may additionally include determining, by a first hash region integral to a memory and associated with the first hash function module, whether an index location of the first hash region corresponding to the first hash value includes an entry. Moreover, the method may include determining, by a second hash region integral to a memory and associated with the second hash function module, whether an index location of the second hash region corresponding to the second hash includes an entry.

  • Publication number: 20110243135
    Abstract: A method may include, by a first network interface: receiving a packet having a flow via a first port of the first network interface; examining the packet to determine an ingress local forwarding identifier (LFID) associated with the flow of the packet; converting the ingress LFID to a global forwarding identifier (GFID) of the network element; and forwarding the packet to a switching element. The method may also include, by the switching element: determining a second network interface for egress of the packet based on the GFID; and forwarding the packet to the second network interface. The method may further include, by the second network interface: converting the GFID to an egress LFID associated with the flow of the packet; and forwarding the packet to a second port of the second network interface and a flow of the second network interface based on the egress LFID.

  • Patent number: 6721808
    Abstract: A client system having a unique object interfacing command shell is disclosed, where the object interfacing command shell allows users to dynamically specify remote objects as commands on a command line. Further, the parameters on the command line are the methods or functions of the remote object. Having the ability to both dynamically create commands and to have a syntactically consistent way of accessing remote objects' methods and functions, without having to know details of the objects' calling interfaces, allows considerable freedom to use remote objects in a fast changing, dynamic context in complex network configurations, and allows less technically sophisticated users to use the objects in scripts and at the command line.
