  • Patent number: 10153967
    Abstract: A network device creates a forwarding table that includes information associated with a set of destinations in a network, and determines next hops for the set of destinations. The network device populates the forwarding table with information associated with the next hops, and stores the forwarding table. The forwarding table is used to forward a multicast packet toward a multiple destinations, and includes separate entries that depend upon routes the multicast packet is to traverse towards destinations with multiple choices for next hops.

  • Patent number: 7630379
    Abstract: The invention relates to network based content inspection (NBCI). More specifically, the invention provides systems and methods for improved NBCI in complex networks that are typical for enterprises and service providers. These networks are shared by large numbers of concurrent users who send and retrieve application content of various sizes via a variety of communication protocols. This invention improves the efficiency of the NBCI of an individual communication session by learning from the processing results of other communication sessions which may be carried via different network protocols. In addition, the invention provides methods that do not weaken the overall security for the network and that improve the stability of NBCI systems by minimizing the risk of system resource exhaustion if subjected to a burst of large payloads. The invention also improves perceived network stability by preventing the system resources from being “live-locked” by a few large content inspection tasks.
