Abstract

An embodiment of the invention provides a method, a device and a system for network package processing, response time of the system can be reduced, system resources are saved, and the efficiency of the network package processing is improved. The method includes the steps that a network package is received and is cached into a first address of an internal memory buffer area; according to the address mapping relation among the first address of the internal memory buffer area, an address of a prestored internal memory buffer area and a physical address of a video memory of a graphics processor (GPU), the physical address of the network package in the video memory of the GPU is determined; a direct memory access (DMA) controller is controlled to write the network package into the determined physical address of the video memory of the GPU where the network package is in; and first indication information is sent to enable a communication opposite end to process the network package according to the first indication information, wherein the first indication information carries the determined physical address of the network package in the video memory of the GPU. The method, the device and the system are applied to the field of computers.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method, device and system for processing network packets. Background technique [0002] With the diversification of network services and applications, the methods of network packet processing are also diversified. The traditional method of using a CPU (Central Processing Unit, central processing unit) to process network packets can no longer meet the requirements of network transmission speed. [0003] At the same time, GPU (Graphics Processing Unit, Graphics Processing Unit) is developing at a speed exceeding Moore's Law, and its floating-point computing capability far exceeds that of CPU. The aspect has been greatly improved, and it has the characteristics of stream processing, high-density parallel computing, and programmable pipeline. The platform for general computing using GPU at the software level is also becoming more and more mature. In particular, the open unified standard O...
