摘要： Methods and apparatus are provided for classifying data packets in a data processing device according to a set of processing rules, wherein, for each of a predetermined group of data items in each packet, each rule defines a rule range indicating a range of possible values of the corresponding data item for which that rule applies. The method comprises for each data packet: (a) performing a preliminary test for at least one data item in said group, the preliminary test comprising testing the value of the data item in the packet for a match with any of a predetermined set of frequently-occurring values for that data item, each frequently-occurring value being associated with a predetermined indicator, and, if a match is obtained, selecting for the data item the indicator associated with the matching frequently-occurring value; (b) performing an item search for any data item in the group for which no match is obtained in a preliminary test, the item search for a said data item comprising selecting a range identifier corresponding to the value of the data item from a predetermined set of range identifiers for that data item, the set of range identifiers indicating, for all possible values of the data item, which of the rule ranges corresponding to the data item in the rule set a value intersects, wherein the indicator associated with a said frequently occurring value for a data item is the range identifier corresponding to that value of the data item; and (c) identifying, based on the selected range identifiers for all data items in the group, at least one rule of any rules applicable to the data packet.

摘要： Classifier for IEEE (Institute of Electrical & Electronics Engineers) 802.11g receiver. A communication device includes a classifier and a number of PHY (physical layer) receivers communicatively coupled thereto that enable the communication device to process various received signal types. Each of the PHY receivers is operable to perform pre-processing of a received frame (or packet) of data and to calculate a confidence level indicating whether the received frame is intended for that particular PHY receiver; this pre-processing does not involve processing (e.g., demodulation and/or decoding) of the received frame. Those PHY receivers having sufficiently high confidence levels assert claims to the classifier for the received frame. The classifier is operable to arbitrate between competing claims by 2 or more PHY receivers and to ensure that the received frame is provided to the PHY receiver for which it is intended.

摘要： Loss of connectivity on a mesh or virtual service (e.g., VPLS) may be restored by nullstitchingnull a healing path between an affected node and another node on the mesh. Connectivity may be restored by nullhealingnull or constructing an alternate path or connection between the affected node and the mesh. Unidirectional and bidirectional healing may be used to establish an alternate path between the affected node and the mesh. Additionally, removing pseudowire connections between the affected node and the mesh may be performed, while establishing a spoke connection to an advertised, available router to create a new connection or nullstitchnull together existing connections.

摘要： Methods and systems for dynamic, rules-based peg counting are disclosed. According to one method, a user creates peg counter definitions using a rules-based language accessible via a graphical user interface. The peg counter definitions are downloaded from an administration server to network monitoring site collectors. The site collectors automatically detect the new peg counter definitions and begin using the new peg counter definitions without ceasing existing peg counting. Peg counter software on the site collectors periodically sends peg counter instances to a data gateway server. The data gateway server aggregates the peg counter instances generated by the various site collectors into system wide peg counter instances.

摘要： A data communication system is provided that comprises a head-end switching system which comprises a plurality of communication ports. A port controller causes the ports to sequentially issue inquiry signals to network termination points. This sequential processing of inquiry signals prevents the formation of phantom links that may occur if physical conductors which are susceptible to crosstalk interference with connected conductors erroneously convey a response signal back to an unattached port within the head-in switching system.
