  • Efficiently hashing packet keys into a firewall connection table
    Patent number: 8112547
    Abstract: A method for increasing the capacity of a connection table in a firewall accelerator by means of mapping packets in one session with some common security actions into one table entry. For each of five Network Address Translation (NAT) configurations, a hash function is specified. The hash function takes into account which of four possible arrival types a packet at a firewall accelerator may have. When different arrival types of packets in the same session are processed, two or more arrival types may have the same hash value.

  • Method and system for determining and graphically representing frame classification rule relationships
    Patent number: 6807576
    Abstract: A method and system for graphically representing relationships between a plurality of filter rules in a computer system is disclosed. The computer system includes a display. Each of the plurality of filter rules has a priority. The method and system include allowing entry of at least one filter rule of the plurality of filter rules and providing a graphical display of a first portion of the plurality of filter rules on the display. Each of the first portion of the plurality of filter rules is displayed hierarchically based on the priority of each of the first portion of the plurality of filter rules.

  • Method, system and computer program product to partition filter rules for efficient enforcement
    Publication number: 20020143724
    Abstract: The effectiveness of a Network Processor to process data at media speed is enhanced by partitioning a Rules Database, used to filter and/or forward frames, into at least one set of Almost-Exact Rules and Other Rules. The Almost-Exact Rules are processed by a Full Match (FM) Tree Search Algorithm and the Other Rules are processed by a Software Managed Tree (SMT) algorithm.
