Data packet processing method and device and edge end equipment

Abstract

The invention discloses a data packet processing method, a data packet processing device and edge equipment. The method comprises the following steps: monitoring a TCP data packet of a transmission layer in a kernel space in an edge end device based on a target queue, wherein the target queue is established after a data stream of the edge end device is redirected to a user space of the edge end device; sending a TCP data packet to a network layer of the kernel space, and extracting a transmission feature corresponding to the TCP data packet; predicting a target packet loss rate of the data packet in a transmission process based on the transmission characteristics; and resending the TCP data packet to the network layer of the kernel space when the packet loss rate meets a preset threshold value and confirmation information sent by the network layer of the kernel space is not received. According to the invention, the data flow is redirected to the user space, accidental packet loss and network delay jitter of the edge-end equipment in a complex network environment can be filtered, meanwhile, in combination with a packet loss probability prediction mechanism, retransmission can be carried out in advance under the conditions that a retransmission request is not received and timeout is not confirmed, and the network efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data packet processing method, device, and edge device. Background technique [0002] With the gradual enrichment of edge computing applications, the demand for stable and efficient network transmission in device-edge-cloud scenarios is increasing. However, the complex and changeable network environment at the edge often causes the active congestion control of the TCP protocol at the bottom of the network due to occasional network jitter and packet loss, which makes the network transmission speed drop sharply, greatly affecting the real-time performance and stability of video applications. [0003] This paper implements a user space configuration TCP network acceleration method. Different from the traditional TCP acceleration method, which often needs to modify the system kernel, such as the BBR algorithm, it focuses on replacing the kernel congestion cont...

Problems solved by technology

Although the kernel-level processing efficiency is high, most of them are cumbersome to install and configure, and cannot be started and stopped at will, or the operating system needs to be restarted

[0004] At the same time, the traditional congestion control algorithm perceives network conditions through packet loss and delay jitter in the network. However, occasional packet loss and delay jitter in the wireless network environment at the edge or ultra-long-distance wired transmission cannot indicate network congestion, and aggressively reduce transmission. The window will greatly reduce the network transmission speed
