Abstract

The present invention provides a method and a device for dispatching streams of a multicore processor. The method comprises the steps of: receiving the streams to be dispatched at the present moment; dispatching the streams to be dispatched at the present moment to each processing unit one by one through a polling way according to weight of the each processing unit of the multicore processor at a previous moment, wherein number of the streams dispatched to the processing unit with a higher weight is greater than the number of the streams dispatched to the processing unit with a lower weight, and the weight is used for identifying the flow that the each processing unit can process; and obtaining the updated weight of the each processing unit after the each processing unit receives the streams to be dispatched at the present moment, and taking the updated weight as the weight of the each processing unit of the multicore processor at the present moment. The device comprises a receiver, a dispetcher and an obtainer.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a stream distribution method and device for a multi-core processor. Background technique [0002] In an operating environment of a multi-core processor, network service traffic is usually processed in parallel by multiple processing units of the multi-core processor. Before the message enters the processing unit, the dispatch module (Dispatch) of the multi-core processor usually identifies and classifies the message uniformly, and then distributes the message to each processing unit according to the classification result. [0003] The distribution module usually distributes flow services on a flow-by-flow basis, which means that different flows are generally sent to different processing units, and packets of the same flow will only enter the same processing unit. Different processing units receive different flows distributed by the distributio...
