  • Publication number: 20090252033
    Abstract: Systems and methods to distribute media content are provided. A particular method includes receiving first link weighting factors and second link weighting factors at a router of a node of a multicast network and determining a primary path to a next hop node based on the first link weighting factors. Additionally, the method includes determining a backup path from a router of the primary path to the next hop node based on the second link weighting factors. The backup path does not overlap any primary path between two nodes of the network. Further, the method includes receiving a data packet from a parent node and routing a copy of the data packet from the router to the next hop node via the backup path, when a network link related to the router has failed. The method also includes routing data packets via a re-configured multicast tree that excludes the failed link.

  • Publication number: 20090209729
    Abstract: A recombinant gene sequence that comprises human SLC gene, antigen gene, and IgG1-Fc fragment gene, wherein the SLC gene is linked upstream to the antigen gene, and the IgG1-Fc fragment is linked downstream to the antigen gene. This invention also relates to the application of the recombinant gene sequence in the preparation of gene vaccine.

  • Publication number: 20090190478
    Abstract: Disclosed herein are systems, methods, and computer readable media for modifying IP backbone link weights such that multicast traffic and unicast traffic will not travel on a same path between nodes. The method comprises assigning link weights to nodes within an IP backbone such that multicast forwarding paths and unicast forwarding paths are failure disjoint, and delivering undelivered multicast packets using IP unicast encapsulation to the loopback address of next hop router on a multicast tree upon link/interface failure.

  • Publication number: 20080253281
    Abstract: Certain exemplary embodiments provide a method comprising: in a network at a node located on a label switched path: selecting a backup path to respond to a failure; and for each link along the backup path, reserving a backup bandwidth, wherein the backup bandwidth is sufficient to reroute traffic around the failure.

  • Publication number: 20080089335
    Abstract: A system and method for routing packet traffic is disclosed. A system that incorporates teachings of the present disclosure may include, for example, a router having a routing element that routes packet traffic according to Internal Gateway Protocol (IGP) weights that prevent multicast packet traffic and unicast packet traffic from occupying a common unidirectional link. Other embodiments are disclosed.

  • Publication number: 20060239219
    Abstract: A method for identifying traffic to an application including the steps of monitoring communication traffic in a network, identifying data from communication traffic content, and constructing a model for mapping the communication traffic for an application derived from data identified from the communication traffic content is described. A related system and computer readable medium for performing the method is also described. The described method and system has utility in a wide array of networks including IP networks.
