摘要： A processing method based on distributed stream computing is performed by a computing device. After receiving flow data sent by an upstream computing node, the computing device stores the flow data into a flow data pool. The computing device collects a data ratio of the flow data in the flow data pool to a total capacity of the flow data pool. When the collected data ratio is greater than or equal to a first threshold, the computing device performs an operation of adding a mark for enabling the upstream computing node to decrease a flow data sending rate; when the collected data ratio is less than or equal to a second threshold, the second threshold being less than the first threshold, the computing device performs an operation of deleting the mark for enabling the upstream computing node to increase the flow data sending rate.

摘要： Described embodiments provide a method of operating a network processor coupled to a network via a communication link. An input/output adapter receives a data packet. A classification module provides control values of the data packet to a statistics module. The statistics module determines (i) updatable statistics based on the control values, and (ii) an address of a statistics bin in a memory of the network processor corresponding to the statistics. Updated values of the statistics are stored at the corresponding address. Values at selected addresses are processed by a control processor of the network processor, generating traffic characteristics for the data packets. The control processor adjusts operation of the network processor based on the traffic characteristics.

摘要： Processing techniques in a network switch help reduce latency in the delivery of data packets to a recipient. The processing techniques include internal cut-through. The internal cut-through may bypass input port buffers by directly forwarding packet data that has been received to an output port. At the output port, the packet data is buffered for processing and communication out of the switch.
