A network data processing method and device based on intel DPDK

Abstract

The present invention provides a network data processing method and device based on Intel DPDK. The method includes: building a data plane development kit Intel DPDK operating environment; using DPDK to add one or more IP addresses, and establishing the one or more The routing information table corresponding to the IP address; the message received by the IP address is forwarded to the corresponding working thread of DPDK for processing, and the message sent by the IP address is sent to the corresponding destination address in the routing information table. The present invention adopts the method of adding IP nodes, realizes the p2p access of all IP multi-nodes, expands the cross-server data packet interaction channel, and can conveniently establish a distributed large system based on DPDK with low cost and high efficiency interconnection of multiple servers.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to an Intel DPDK-based network data processing method and device. Background technique [0002] DPDK (Data Plane Development Kit, Data Plane Development Kit) is a software development kit for high-speed network data packets proposed by Intel Corporation, which is now open source. In the early stage, it mainly supported systems using Intel CPUs and network cards. Now it supports other CPUs such as IBM Power and Cavium, as well as some non-Intel network cards. DPDK directly reads and writes to the network card by bypassing the network protocol stack of the Linux system, combined with the binding of different cores in the multi-core CPU, it can realize line-speed sending and receiving under 10Gbit network packet traffic. [0003] Such as figure 1 The normal DPDK model shown in the figure is currently based on the parallel processing method of network data packets based on Int...

Problems solved by technology

[0004] However, this method of using DPDK is only suitable for the use of DPDK on a single server. When multiple servers are used to build a large business plane system, it is difficult to expand the system scale

For example, there is no suitable interaction method for message interaction between multiple servers, DPDK message interaction between cross-server DPDK or protocol stack to another server.

Moreover, multiple modules between the operating system protocol stack and DPDK in the same server share a channel, and if one module does not release the buffer, it will affect other modules.

In addition, the method of "message passing pointer" can easily lead to confusion in pointer management, increased memory risk, and reduced system stability.
