    摘要： The present invention relates to a system and computer-readable medium for storing a plurality of multi-field classification rules in a computer system. Each multi-field classification rule includes a rule specification that itself includes a plurality of fields and a plurality of field definitions corresponding to the fields. The method of the present invention includes providing a virtual rule table, where the table stores a plurality of field definitions, and for each of the plurality of multi-field classification rules, compressing the rule specification by replacing at least one field definition with an associated index into the virtual rule table. The method also includes storing each of the compressed rule specifications and the virtual rule table in a shared segment of memory.

    摘要： Method for compressing search tree structures used in rule classification is provided. The method includes classifying packets based on filter rules, compressing a tree structure comprising multiple levels of single bit test nodes and leaf nodes, storing the compressed tree structure in a first memory structure of a storage such that the multiple levels of single bit test nodes and leaf nodes can be accessed from the first memory structure through a single memory access of the storage, collecting single bit test nodes of the tree structure that are in a lowest level of the tree structure, storing only the collected single bit test nodes within a second memory structure of the storage that is contiguous to the first memory structure, collecting leaf nodes of the tree structure, and storing only the collected leaf nodes within a third memory structure of the storage that is contiguous to second memory structure.

    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.
