Parallel processing method of network data packets based on intel DPDK

Abstract

The invention discloses a network data packet parallel processing method based on an Intel DPDK (Data Plane Development Kit). The method comprises the following steps: step 1, establishing an Intel DPDK running environment; step 2, creating a memory pool, and creating a RX memory ring for receiving the network data packet and a TX memory ring for transmitting the network data packet; step 3, setting a network data packet scheduling strategy, and preparing to perform network data packet scheduling; step 4, creating multiple worker threads, and performing parallel processing of the network data packet. In the method provided by the invention, performance advantage of a multi-core CPU is used fully, and by lock-free data structure design, parallel network processing framework and high-efficiency network data packet distribution, parallel processing of the network data packet on multiple CPU cores is realized.

Description

technical field

[0001] The invention relates to an Intel DPDK-based network data packet parallel processing method, belonging to the technical field of network data packet processing. Background technique

[0002] With the development of network communication technology, network bandwidth increases rapidly, 1Gbit and 10Gbit networks are gradually popularized, and 40Gbit networks are widely used in telecom operators and large-scale enterprise-level backbone networks. The exponential growth of network traffic poses new challenges to the performance of network data packet analysis and processing network products such as firewalls, IDS / IPS, and application gateways. Traditional network data packet processing methods face problems such as high packet loss rate, large delay, and high system load in a high-speed network environment, and cannot meet the real-time processing of network data packets in a high-speed network environment. At present, the industry mainly has the followin...
