Data packet transmission method and system based on 5G communication

Abstract

The invention discloses a data packet transmission method and system based on 5G communication. The method comprises the steps that network card equipment acquires a data packet from a network link; the network card equipment stores the acquired data packet in a high-speed cache; the CPU forwards and processes the data packet in the cache; the network card equipment reads the data packet which has been forwarded and processed by the CPU in the cache; and the network card equipment sends out the data packet which is read from the cache and is forwarded and processed by the CPU. According to the invention, the network card equipment is arranged to directly read and write the data from the cache, so that the memory is prevented from being read and written in the receiving, forwarding and sending processes of the data packet, and the data packet is temporarily stored by using the memory with large capacity when the cache is insufficient, so that the normal operation of the system under complex conditions is ensured; the delay time of data packet forwarding is greatly reduced, and the overall forwarding capability of the system is improved.

Description

Technical field [0001] The present invention relates to the field of 5G communication technology, and more particularly to a 5G communication-based data packet transmission method, a system, and a computer readable storage medium. Background technique [0002] The fifth generation mobile communication technology (5th GenerationWireless Systems, 5th-Generation, 50G or 5G technology) is the latest generation of cellular mobile communication technology, but also 4G (LTE-A, WiMAX), 3G (UMTS, LTE) ) And 2G (GSM) system extension. 5G performance goals are high data rates, reduce delays, save energy, reduce costs, improve system capacity and large-scale device connections. [0003] 5G communication user plane forwarding refers to a 5G communication system user plane packet forward, such as figure 1 As shown, the forwarding process of the packet includes the following steps: [0004] Step 1: NIC device collects packets from the network link; [0005] Step 2: The network card is stored in...

AI Technical Summary

Problems solved by technology

[0013] The main purpose of the present invention is to provide a data packet transmission method and system based on 5G communication, aiming at solving the problem that each forwarded data packet in the prior art must pass through The processing of reading and writing memory devices twice significantly increases the delay time of data packet forwarding and reduces the overall forwarding capability of the system
