Abstract

The invention provides a multicore CPU (Central Processing Unit) load balancing method and device. The method comprises the following steps: receiving media stream data sent from each media stream transmitting end by network equipment; analyzing the media stream data sent from each media stream transmitting end, and obtaining a destination port of the media stream data of each media stream transmitting end; according to the destination port, obtaining a processing CPU corresponding to the media stream data of each media stream transmitting end, wherein the processing CPU corresponding to the media stream data is a determined CPU with the minimum load when the media stream data of each media stream transmitting end is subjected to CPU processing time consumption prediction in network equipment after the network equipment carries out the CPU processing time consumption prediction on the media stream data sent from a plurality of media stream transmitting ends within unit time; and using the processing CPU to process the media stream data. When the multicore CPU load balancing method and device is applied, the load balancing between the multicore CPUs can be effectively realized, and the capability of the network equipment to carry out parallel processing on the media stream data is improved.

Description

Technical field [0001] The present invention relates to the technical field of multimedia communication, in particular to a method and device for multi-core CPU load balancing. Background technique [0002] In the field of multimedia communication technology, the data that needs to be transmitted or processed is very large, so the data throughput capability of network devices is high. For network devices that include multi-core CPUs, improving the load balance between multi-core CPUs is an effective way to increase the data throughput of network devices. [0003] In the prior art, a network device can calculate the hash value of the source IP address, destination IP address, and port number of a data packet by using a hash function, and send data packets with different hash values ​​to the receiving data packet queue of the corresponding CPU. In the process, the CPU receives and processes the data packet to realize the balanced processing of the data packet among the multi-core CP...
