Embodiment 1

[0048] Such as figure 1 Shown, in an embodiment of described data packet receiving method, comprise steps:

[0049] S100. Determine the target reading time according to the current polling time, and read the data packet from the buffer according to the target reading time;

[0050] S200. Acquire read information during the process of reading data packets from the buffer, and update the polling time according to the read information;

[0051] Wherein, the reading information includes waiting times and reading times, the reading times are updated when trying to read data packets, and the waiting times are updated when no data packets are read.

[0052] Specifically, the terminal receives the data packet through the network card, and the network card stores the data packet in the buffer after receiving the data packet from the network. process. Such as figure 2 As shown, in the prior art, each time the network card receives a data packet, the DMA engine of the network card fir...

Embodiment 2

[0087] Based on the above embodiments, the present invention also provides a corresponding data packet receiving device, such as Figure 5 As shown, the data packet receiving device includes:

[0088] A packet receiving module, the packet receiving module is used to determine the target reading time according to the current polling time, and read the data packet from the buffer according to the target reading time, specifically as described in Embodiment 1;

[0089] An update module, the update module is used to acquire read information in the process of reading data packets from the buffer, and update the polling time according to the read information, wherein the read information It includes waiting times and reading times. The reading times are updated when trying to read data packets, and the waiting times are updated when no data packets are read. The details are as described in the first embodiment.

Embodiment 3

[0091] Based on the above embodiments, the present invention also provides a corresponding terminal, such as Figure 6 As shown, the terminal includes a processor 10 and a memory 20 . Figure 6 Only some components of the terminal are shown, but it should be understood that implementation of all illustrated components is not required, and more or fewer components may be implemented instead.

[0092] The storage 20 may be an internal storage unit of the terminal in some embodiments, such as a hard disk or memory of the terminal. In other embodiments, the memory 20 may also be an external storage device of the terminal, such as a plug-in hard disk equipped on the terminal, a smart memory card (Smart Media Card, SMC), a secure digital (SecureDigital, SD ) card, flash memory card (Flash Card), etc. Further, the memory 20 may also include both an internal storage unit of the terminal and an external storage device. The memory 20 is used to store application software and various ...

Abstract

The invention discloses a data packet receiving method and device, a terminal and a storage medium, and the method comprises the steps: determining a target reading duration according to the current polling time, and reading a data packet from a buffer region according to the target reading duration; and reading information in the process of reading the data packet from the buffer area is obtained, and the polling time is updated according to the reading information; wherein the reading information comprises the number of waiting times and the number of reading times, the number of reading times is updated when the data packet is tried to be read, and the number of waiting times is updated when the data packet is not read. According to the invention, the duration of reading the data packet from the buffer area can be dynamically adjusted according to the rate of the data packet in the network flow and the actual reading capability of the system, so that the situation that receiving interruption is triggered for multiple times to enter a polling state when the data packet of the low-rate network flow is received is prevented, and the receiving efficiency of the data packet is improved.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a data packet receiving method, device, terminal and storage medium. Background technique [0002] The existing Linux operating system adopts the NAPI mechanism when receiving data packets. This mechanism combines the terminal mode with the polling mechanism. When the data packet arrives, the data packet is first stored in the buffer through the network card, and then the network card is activated to receive the interrupt. Enter the packet receiving interrupt processing routine. In the packet receiving interrupt processing routine, first turn off the packet receiving interrupt of the network card, and then wait for the corresponding polling function of the network card to be scheduled. When the corresponding polling function of the network card is scheduled, read each time M data packets, if there are redundant data packets in the buffer after reading M data packets,...
