摘要： The preferred embodiments of the present invention are directed to estimating entropy of origin-destination (OD) data flows in a network. To achieve this, first and second sketches are created corresponding to ingress (i.e. origin) and egress (i.e. destination) flows. The sketches allow estimating entropy associated with data streams as well as entropy associated with an intersection of two or more of the data streams, which provides a mechanism for estimating the entropy OD flows in a network.

摘要： A system and method for detecting and diagnosing routing problems in a network in real-time by recording TCP flow information from at least one server to at least one prefix, and observing retransmission packets communicated from the at least one server to the at least one prefix. When a predetermined threshold for TCP flows to a prefix is reached, traceroutes may be triggered to a destination in the prefix, and the traceroutes analyzed to determine whether to issue an alarm for a routing failure. The system includes a real-time data collection engine for recording unidirectional TCP flow information, a real-time detection engine for observing the retransmission packets and issuing a warning upon a retransmission counter exceeding a predetermined threshold, and a real-time diagnosis engine for triggering at least one traceroute to a destination in the prefix that is randomly selected from TCP flows in retransmission states.

摘要： A method and system for providing query aware partitioning are disclosed. For example, the method receives a query plan comprising a plurality of queries, and classifies each one of the plurality of queries. The method computes an optimal partition set for each one of the plurality of queries, and reconciles the optimal partition set of each one of the plurality of queries with at least one subset of queries of the plurality of queries. The method selects at least one reconciled optimal partition set to be used by each query of the plurality of queries, and stores the selected at least one reconciled optimal partition set in a computer readable medium.

For example, the method monitors a timer for a time threshold associated with a burst of a plurality of bursts of packets, and determines if the timer for the time threshold associated with the burst has expired. The method predicts an inter-burst time for the burst, if the timer for the time threshold associated with the burst has expired and sets the dynamic inactivity timer in accordance with the inter-burst time for the burst.
