  • Patent number: 8954429
    Abstract: Implementing query classification includes receiving a core term from a search query responsive to execution of a first module. The first module searches a table for the core term and yields a first result. The query classification also includes receiving a second result from the search query responsive to execution of a second module. The second module searches an index of terms that are mapped to documents and corresponding categories in the index. The second result is indicative of one of the corresponding categories in the index based on a probability score. Upon determining the first result is a category associated with the core term in the table, the query classification also includes calculating a weighted average for the first result and the second result. The calculation yields a third result. The query classification further includes transmitting the third result to a computer device that generated the query.

  • Patent number: 8953435
    Abstract: An example method involves generating, without manual intervention, a table to store current reroute statistics based on rerouting of data from a logical circuit that has failed to a logical failover circuit in a network. The current reroute statistics include trap data corresponding to the logical circuit. The trap data includes a committed burst size. The logical circuit is identified by a first logical circuit identifier. The logical failover circuit is identified by a second logical circuit identifier. The first and second logical circuit identifiers are renamed until the logical circuit has been restored from failure. The table is updated, without manual intervention, to store updated reroute statistics. The updated reroute statistics include updated trap data corresponding to the logical circuit. The updated reroute statistics are based on a change in status of the logical circuit corresponding to a dropped frame when the committed burst size has been exceeded.

  • Patent number: 8955117
    Abstract: Method, system and computer-readable device to locate a prefix hijacker of a destination prefix within a one-hop neighborhood. The method includes generating one-hop neighborhoods from autonomous system-level paths associated with a plurality of monitors to a destination prefix. The method also includes determining a suspect set of autonomous system identifiers resulting from a union of the one-hop neighborhoods. The method further includes calculating a count and a distance associated with each autonomous system identifier in the suspect set of autonomous system identifiers. The count represents how often an autonomous system identifier appears in the one-hop neighborhoods. The distance represents a total number of autonomous system identifiers from the autonomous system identifier to autonomous system identifiers associated with the plurality of monitors.

  • Patent number: 8949877
    Abstract: A method of determining demand for multimedia content in a multimedia provider network includes receiving a content demand statistics (CDS) request from a client application where the request identifies a subscriber set. Responsive to the CDS request, selected CDS data is retrieved from a CDS subsystem. The CDS data is indicative of demand for multimedia content among subscribers in the subscriber set. The retrieved CDS data is delivered to the client application. The selected data may be selected from past data, present data, and future data. The CDS request indicates a set of buddy subscribers and the messaging server retrieves CDS data associated with the buddy subscribers. A security subsystem may be accessed and to determine, prior to retrieving CDS data for a particular buddy subscriber, whether the particular buddy subscriber has authorized the requesting subscriber.
