摘要： A method and system for monitoring traffic in a data communication network and for extracting useful statistics and information is disclosed. In accordance with an embodiment of the invention, a network interface card has a run-time system and one or more processing blocks executing on the network interface. The run-time system module feeds information derived from a network packet to the processing modules which process the information and generate output such as condensed statistics about the packets traveling through the network.

摘要： A method and system for extracting useful statistics and information and removing a processing module based on the information to enhance a run-time system on a network interface card is disclosed. The run-time system module feeds information derived from a network packet to processing modules which process the information and generate output such as condensed statistics about the packets traveling through the network. The run-time system can be enhanced to included facilities for removing processing modules without replacing the run-time system module.

摘要： The present invention provides an architecture that advantageously leverages multiple content distribution networks to provide enhanced services. In accordance with an embodiment of the present invention, a share of content requests are served by each of a plurality of content distribution networks. The fraction of content requests served by a particular content distribution network can be determined dynamically, depending on the offered load or other traffic characteristics.

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.

摘要： A method and system are disclosed for operating a high speed data stream management system which runs a query plan including a set of queries on a data feed in the form of a stream of tuples. A predicate prefilter is placed outside the query plan upstream of the set of queries, and includes predicates selected from those used by the queries. Predicates are selected for inclusion in the prefilter based on a cost heuristic, and predicates are combined into composites using a rectangle mapping heuristic. The prefilter evaluates the presence of individual and composite predicates in the tuples and returns a bit vector for each tuple with bits representing the presence or absence of predicates in the tuple. A bit signature is assigned to each query to represent the predicates related to that query, and a query is invoked when the tuple bit vector and the query bit signature are compatible.

摘要： A system, method and computer-readable medium provide for assigning sampling methods to each input stream for arbitrary query sets in a data stream management system. The method embodiment comprises splitting all query nodes in a query directed acyclic graph (DAG) having multiple parent nodes into sets of independent nodes having a single parent, computing a grouping set for every node in each set of independent nodes, reconciling each parent node with each child node in each set of independent node, reconciling between multiple child nodes that share a parent node and generating a final grouping set for at least one node describing how to sample an input stream for that node.
