Abstract: Embodiments relate to a method, system, and computer program product for processing database grouping set query. The method includes receiving a grouping set query request; the grouping set query request including a plurality of groups and determining via said grouping set query request a plurality of to be assigned child tasks for parallel processing. Subsequently, one or more of the groups are assigned as child tasks to be parallel processed based on logical relationship among the groups and the number of available parallel child tasks determined and the parallel child tasks are executed to generate grouping set query result.

Abstract: Presented are methods and systems for providing bandwidth estimation and correction in a communications network. Bandwidth estimation and correction can include calculating a round trip time (RTT) value and a packet loss rate (PLR) value for each packet of a set of packets transmitted at different points in time from a server to a client terminal over the communications network; determining a bandwidth estimate based on the RTT and PLR values for the set of packets transmitted; determining a bandwidth measurement based on the RTT and PLR values for the set of packets; and determining a corrected bandwidth estimate based on the bandwidth estimate and the bandwidth measurement.
