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.

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, computer readable medium and apparatus for hashing wireless traffic are disclosed. For example, the method hashes the wireless traffic uniformly by a plurality of probe servers based on at least one first key to provide a plurality of streams, and hashes at least one output stream of each of the plurality of probe servers uniformly based on at least one second key to provide a plurality of output streams. The method then provides the plurality of output streams to at least one aggregator server.

摘要: The preferred embodiments of the present invention can include sampling packets transmitted over a network based on the content of the packets. If a packet is sampled, the sampling unit can add one or more fields to the sampled packet that can include a field for a number of bytes contained in the packet, a packet count, a flow count, a sampling type, and the like. The sampled packets can be analyzed to discern desired information from the packets. The additional fields that are added to the sampled packets can be used during the analysis.
