  • Patent number: 10462015
    Abstract: The embodiments herein uses sensor APs (e.g., APs that do not associate with client devices) to detect changes in physical topology that affect cell coverage areas and determine cell edges for different client devices. In one embodiment, using test signals (e.g., test probes) transmitted by the sensor APs which are received at normal APs which do associate with client devices, a controller can generate baselines which characterize the signals received from the sensor APs at the normal APs. At intervals or in response to an unexpected action by a client device, one or more of the sensor APs can transmit another test signal. Because the test signal can be received at multiple normal APs, the controller can compare the test signal to the baselines to identify whether there has been a change in physical topology that affects the cell coverage area for the client device.

  • Patent number: 10178026
    Abstract: A packet broker deployed in a visibility fabric may intelligently assign identifiers to data packets that are routed through sequences of one or more network tools for monitoring and/or security purposes. More specifically, the packet broker may apply packet-matching criteria to incoming data packets to determine a predetermined sequence of network tools through which the data packets are to be guided. For example, the packet broker may guide a data packet through a predetermined sequence of network tools by translating an internal identifier added to the data packet to an external identifier before transmission to each of the network tools, and translating the external identifier to a different internal identifier each time the data packet is received from each of the network tools.

  • Patent number: 10169388
    Abstract: Methods and systems allow indexing references to documents of a database according to database reference profiles. Documents may then be located in the database using decoding protocols based on the database reference profiles. To this end, the documents are stored in the database and searchable terms extracted therefrom are associated with posting lists. Each posting list is divided into blocks of M database references. The blocks are encoded according to a pattern that depends on the M database references. A corresponding pointer to a table of encoding patterns is appended to each block. When a query is received for a searchable term, blocks are extracted from a posting list corresponding to the searchable term and a pointer for each block is used to extract a decoding protocol related to an encoding pattern for the block.

  • Patent number: 10063454
    Abstract: An apparatus and method for testing an upstream path of a cable network are disclosed. The upstream path is tested by capturing and analyzing upstream data packets generated by a specific terminal device. A test instrument is connected at a node of the cable network. The test instrument establishes a communication session with the headend, informing the headend of an identifier of the device that will generate the test upstream data packet. The test upstream data packet is captured and analyzed at the headend, so that the results of the analysis can be communicated back to the test instrument. To speed up the packet capturing and filtering process, the upstream data packets can be pre-filtered based on packet duration and/or arrival time.
