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...

Performance problems in any link will seriously affect the performance of the entire application

Among the three mainstream methods mentioned above, although the PF_RING method has greatly improved the packet capture rate, there are still many packet loss rates, and the CPU load is high, which cannot meet the needs of commercial applications; the traditional DPDK-based method mainly focuses on data The line-speed sending and receiving of packets, when the processing of data packets is added, its performance will drop significantly, and the line-speed receiving, processing and sending of data packets cannot be achieved; although the hardware smart network card method can significantly reduce the host CPU load, but On the one hand, an additional expensive hardware smart network card needs to be configured; on the other hand, the CPU of the host machine cannot be fully utilized, wasting resources, so it is not suitable for ordinary commercial applications
