Abstract

The invention discloses a method for reducing the data transmission delay, which comprises the steps that network equipment acquires data packet characteristics of a data packet to be scheduled; the network equipment searches a processing core corresponding to the data packet characteristics of the data packet to be scheduled according to a preset corresponding relationship between the data packetcharacteristics and processing cores in a multi-core processor; and the network equipment processes the data packet according to the searched processing core. Therefore, the data packet can be effectively prevented from being processed by the same processing core. The corresponding processing core is selected for processing according to the data packet characteristics, so that the processing coreutilization rate of the multi-core processor is effectively improved, the data packet can respond more timely, and the data transmission and processing speed is improved.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a method, device and equipment for reducing transmission delay. Background technique [0002] With the development of chip manufacturing technology, more and more processor chips are beginning to develop into multi-core chips. By integrating multiple complete computing engines or cores in one processor, the computing performance of the entire processor can be improved as a whole. For example, processors in more and more routers are multi-core chips. [0003] In the current communication products such as wireless routers, the WiFi chip usually runs on a certain core of the multi-core processor, and the interruption cannot be responded in time, so that the data transmission efficiency of the wireless router is not high. Contents of the invention [0004] The embodiment of the present application provides a network device and a method for reducing dat...
