  • Correlating data streams of different protocols
    Patent number: 7330896
    Abstract: A single address configuration table entry maps multiple source devices in a source network to a single destination device in a destination network. The single address configuration table entry is used when any of the source devices initiates a connection to the destination device. The single address configuration table entry includes a “wildcard” for matching the source address of connection requests that are originated by any of the multiple source devices and destined for the destination device. When a connection is initiated by a source device, certain address/channel information is dynamically allocated in order to map the source device to the destination device. A dynamic routing table entry is installed in a dynamic routing table in order to map the source device to the destination device using the dynamically allocated address/channel information.

  • Routing table for forwarding Internet Protocol (IP) packets through a communications network
    Patent number: 7233579
    Abstract: Described are a system and computer-implemented method for searching and updating a routing table for forwarding IP packets through a communications network. Records containing IP address prefixes are organized in a binary tree data structure. When inserting a new record, one of the records in the binary tree data structure is identified as an enclosing record having an associated record data range that encloses record data of the new record. An enclosing pointer of the new record is set to point to the identified enclosing record. When searching for a longest matching prefix for a destination IP address, the binary tree data structure is traversed and one of the records in the binary tree data structure is identified as an enclosing record, which is returned as the longest matching prefix.
