Abstract

The embodiment of the invention provides a data packet receiving method and device, electronic equipment and a storage medium. The method comprises the steps that after a packet receiving interruption event is responded and packet receiving interruption is closed, whether the packet receiving number of data packets received last time by a packet receiving work queue is larger than a first preset number threshold value or not and packet receiving time consumption is smaller than first preset duration or not is judged; if yes, dormancy is carried out for a second preset duration; and if not, starting the packet receiving work queue to receive the data packets, and recording the packet receiving quantity and packet receiving time consumption of the data packets received this time. According to the data packet receiving method provided by the embodiment of the invention, the problem of equipment failure caused by network data flooding is effectively solved by optimizing a network port driving NAPI packet receiving mechanism, and the reliability of the equipment is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communications, and in particular to a data packet receiving method, device, electronic equipment, and storage medium. Background technique [0002] In the prior art, the Linux system adopts the NAPI (New API) mechanism when receiving data packets. This mechanism combines the interrupt mode with the polling mode. The advantage of the interrupt is that the response is timely. More CPU time; the disadvantage is that when the amount of data is large, too many interrupts will be generated, and each interrupt will consume a lot of CPU time, resulting in a higher efficiency than polling. The polling method is opposite to the interrupt method. It is more suitable for processing a large amount of data, because each polling does not need to consume too much CPU time; the disadvantage is that it takes up CPU time even when only a small amount of data is received or no data is received. NAPI i...
