In general, in one aspect, the disclosure describes a method of determining if a first query for data related to a protocol data unit in a first table is a query to a table merged into a combination table formed from multiple tables. If so, the method can generate a second query for the first query for data stored by the combination table.

Merger of tables storing protocol data unit related data

Embodiments of the present invention relate to a method and system for automatically configuring network processing software to reduce memory latency associated with parallel processing using a plurality of processing elements.

Method and system for configuring network processing software to exploit packet flow data locality

A method and apparatus for two-stage packet classification. In the first stage, which may be implemented in software, a packet is classified on the basis of the packet's network path and, perhaps, its protocol. In the second stage, which may be implemented in hardware, the packet is classified on the basis of one or more transport level fields of the packet. An apparatus of two-stage packet classification may include a processing system for first stage code execution, a classification circuit for performing the second stage of classification, and a memory to store a number of bins, each bin including one or more rules.

Apparatus and method for two-stage packet classification using most specific filter matching and transport level sharing

A method and apparatus for two-stage packet classification, the two-stage packet classification scheme including a first stage and a second stage. In the first classification stage, a packet is classified on the basis of the packet's network path. In the second stage of classification, the packet is classified on the basis of one or more transport (or other) fields of the packet. Also disclosed are embodiments of most specific filter matching and transport level sharing, and either one or both of these techniques may be implemented in the two-stage classification method.
