Abstract

Embodiments of the invention disclose a DPDK-based message processing method and computer equipment, relate to the technical field of computers, and aim at solving the problem of network card universality caused by the reason that kernel modes are required to support network cards with specific drives when user mode spaces adopt a DPDK manner or the problem that the message reception / transmissionefficiency of kernel mode spaces is relatively low as network cards adopt common drives. The method is applied in the computer equipment. The computer equipment is installed with an operation system,wherein the operation system comprises a user mode space and a kernel mode space; the user mode space is provided with a data plane development kit DPDK reception / transmission interface; the kernel mode space is provided with a network card reception / transmission module; and a queue is arranged between the DPDK reception / transmission interface and the network card reception / transmission module. The method comprises the step of transmitting messages to network cards or receiving messages from the network cards by the DPDK reception / transmission interface and the network card reception / transmission module through queue transmission. The method is applied in the process of receiving messages from network cards or transmitting messages to the network cards by the computer equipment.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a DPDK-based message processing method and computer equipment. Background technique [0002] With the need of high-speed data forwarding, a data plane development kit (Data Plan Develop Kit, DPDK) technology emerges as the times require. DPDK technology is a message processing framework based on the data plane developed by Intel (INTEL). DPDK can support fast forwarding of data. It is a library and driver set for fast processing of messages on the X86 platform. In most cases, it works in the Linux user mode space , is widely used in the development of Layer 2 or Layer 3 forwarding functions. In order to cooperate with the Linux user mode space to use the DPDK method for fast data forwarding, the Linux kernel mode space needs to be able to realize high-speed data transmission and reception from the network card. An optional solution in the prior art is to use a n...
