摘要： A process control method and system including partitioning transmit decisions and certain measurements into one logical entity (Data Plane) and partitioning algorithm computation to update transmit probabilities into a second logical entity (Control Plane), the two entities periodically communicating fresh measurements from Data Plane to Control Plane and adjusted transmit probabilities from Control Plane to Data Plane. The transmit probability may be used in transmit/discard decisions of packets or instructions exercised at every arrival of a packet or instruction. In an alternative embodiment, the transmit probability may be used in transmit/delay decisions of awaiting instructions or packets exercised at every service event.

摘要： The present invention relates to a method and computer system device for applying a plurality of rules to data packets within a network computer system. A filter rule decision tree is updated by adding or deleting a rule. If deleting a filter rule then the decision tree is provided to a network data plane processor with an incremental delete of the filter rule. If adding a filter rule then either providing an incremental insertion of the filter rule to the decision tree or rebuilding the first decision tree into a second decision tree responsive to comparing a parameter to a threshold. In one embodiment the parameter and thresholds relate to depth values of the tree filter rule chained branches. In another the parameter and thresholds relate to a total count of rule additions since a building of the relevant tree.

摘要： The classification system of a network device includes a cache in which a mapping between predefined characteristics of TCP/IP packets and associated actions are stored in response to the first “Frequent Flyer” packet in of a session. Selected characteristics from subsequent received packets of that session are correlated with the predefined characteristics and the stored actions are applied to the received packets if the selected characteristics and the predefined characteristics match, thus reducing the processing required for subsequent packets. The packets selected for caching may be data packets. For mismatched characteristics, the full packet search of the classification system is used to determine the action to apply to the received packet.
