    摘要: A monitor for and a method of examining packets passing through a connection point on a computer network. Each packets conforms to one or more protocols. The method includes receiving a packet from a packet acquisition device and performing one or more parsing/extraction operations on the packet to create a parser record comprising a function of selected portions of the packet. The parsing/extraction operations depend on one or more of the protocols to which the packet conforms. The method further includes looking up a flow-entry database containing flow-entries for previously encountered conversational flows. The lookup uses the selected packet portions and determining if the packet is of an existing flow. If the packet is of an existing flow, the method classifies the packet as belonging to the found existing flow, and if the packet is of a new flow, the method stores a new flow-entry for the new flow in the flow-entry database, including identifying information for future packets to be identified with the new flow-entry. For the packet of an existing flow, the method updates the flow-entry of the existing flow. Such updating may include storing one or more statistical measures. Any stage of a flow, state is maintained, and the method performs any state processing for an identified state to further the process of identifying the flow. The method thus examines each and every packet passing through the connection point in real time until the application program associated with the conversational flow is determined.

    摘要: Systems and methods for providing wireless services to a plurality of user equipments (UEs) is disclosed. A device can have a plurality of antennas, each having two or more beams. The plurality of antennas can divide the coverage area into sectors based on the two or more beams of each antenna, and each beam can overlap with a beam in an adjacent sector. The device can transmit a reference signal in each sector via the associated beam, received one or more measurement reports from UEs within each sector, indicating a received quality of at least one reference signal. The device can assign a sector edge UE to a sector based on the measurement report.

    摘要: A cache system for looking up one or more elements of an external memory includes a set of cache memory elements coupled to the external memory, a set of content addressable memory cells (CAMs) containing an address and a pointer to one of the cache memory elements, and a matching circuit having an input such that the CAM asserts a match output when the input is the same as the address in the CAM cell. The cache memory element which a particular CAM points to changes over time. In the preferred implementation, the CAMs are connected in an order from top to bottom, and the bottom CAM points to the least recently used cache memory element.
