摘要： A method includes that a streaming media server receives a play request that is for one channel of streaming media and that is sent by a client. The streaming media server selects N streaming media buffer nodes from M streaming media buffer nodes that buffer segments of the streaming media. The streaming media server sends a streaming media playlist to the client, where M is greater than N. When N is 1, the one selected streaming media buffer node buffers all segments of the streaming media. When N is greater than 1, the N selected streaming media buffer nodes each buffer a part of segments of the streaming media. The streaming media playlist includes addresses of the N streaming media buffer nodes, and indicates the client to obtain the segments of the streaming media based on the addresses of the N streaming media buffer nodes to play the streaming media.

摘要： A source end obtains to-be-transmitted data, divides the to-be-transmitted data into a plurality of segments, determines a sending sequence number of each segment, generates verification information of each segment based on the segment and the sending sequence number of the segment, and then sends the plurality of segments and corresponding verification information to a destination end. In this way, the destination end may verify a received segment based on a receiving sequence number and the verification information of each segment, to determine whether a transmission exception exists in the segment in a transmission process. Therefore, when verifying that a transmission exception occurs in the segment, the destination end may determine that a transmission exception exists in the to-be-transmitted data, without a need to wait until transmission of the entire to-be-transmitted data is completed, so that verification efficiency of the to-be-transmitted data is effectively improved.

摘要： A data processing method is provided, including: sending, by an operation node, an alarm signal to a control node when a monitor detects that processing performance of data from a first data transmission pipe is lower than a first threshold (S102), where the alarm signal is used to indicate that the processing performance of the data from the first data transmission pipe is low; and when receiving the alarm signal, reducing, by the control node, a data amount that is from the first data transmission pipe and that is allocated to the operation node (S103). The solution can reduce fluctuation in processing performance of the data processing system during traffic control.

摘要： A data query method includes: receiving a data query request during a data query, where the data query request specifies data ranges in a plurality of dimensions; obtaining spatial distribution information of multi-dimensional data, where the spatial distribution information records data ranges, in each dimension, of a plurality of subspace objects associated with the multi-dimensional data; determining, from the multi-dimensional data based on the spatial distribution information of the multi-dimensional data, a block that meets the data ranges in the plurality of dimensions specified by the data query request; and searching the determined block for data that meets the data ranges in the plurality of dimensions specified by the data query request.

摘要： This application provides a service execution system including a service execution apparatus and a decision apparatus. The service execution apparatus collects a first quantity of service requests from a received service request, to obtain a first sample set, and sends the first sample set to the decision apparatus. The decision apparatus evaluates a first model and a first policy based on the first sample set, then the decision apparatus processes following steps basing on evaluation result of the first model.

摘要： Embodiments of this application provide a data processing method in a database. A plurality of aggregation intervals are selected, wherein the plurality of aggregation intervals are different from each other. And at least one piece of data in the database is aggregated separately based on each aggregation interval, so that data clusters stored in the database have data ranges with different attribute value spans.
