Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an intelligent network card provided in an embodiment of the present application, where the intelligent network card includes:
the intelligent network card comprises two data optical ports, each data optical port is connected with a data separation module, and the data separation module is connected with an IP core in the FPGA; the CPU is directly connected with the FPGA by an internal bus; and the CPU is simultaneously provided with an embedded linux system and a freeRTOS system.
The application provides an intelligent network card based on a ZynqMP platform. ZYNQ is an extensible processing platform and can be seen as an A9 core processor with FPGA peripheral equipment. As shown in FIG. 1, the CPU will be described below as including Cortex-A53 and Cortex-R5. When the CPU includes Cortex-A53 and Cortex-R5, the embedded linux system may be run on Cortex-A53 and the freeRTOS system run on Cortex-R5. In fig. 1, the IP core in the FPGA is mccdma. Of course different IP cores for different CPUs. The internal bus adopted between the FPGA and the CPU is an AXI bus. The AXI bus is used because the protocols of Cortex-a53 and Cortex-R5, as exemplified in fig. 1, support the AXI bus. Therefore, it can be understood that the internal bus employed by the CPU and FGPA should be supported by the CPU.
The embedded liunux system runs on Cortex-A53 and is used for loading u-boot, kernel and file systems and running application programs. The real-time system freeRTOS runs on Cortex-R5 and is used for running a monitoring program after being powered on.
In the starting process of the intelligent network card, bit files can be downloaded from fsbl to FPGA from QSPI Flash (Quad SPI, four-wire SPI bus) to obtain information such as system configuration parameters. The FPGA is also called PL (programmable Logic) terminal.
It should be noted that the two data optical ports have completely identical functions, and the two optical ports operate simultaneously.
The data separation module divides the data message transmitted from the data optical port into control plane traffic and data plane traffic. Fig. 1 includes two data separation modules, which can improve the separation efficiency of data packets.
Of course, it can be understood that, on the basis of this embodiment, the intelligent network card may further include other data processing modules or units, for example, the application acceleration module may accelerate the network, and the like.
The method and the device have the advantages that two paths of data optical ports are designed to increase bandwidth processing capacity and load balance, and the network card is remotely subjected to rule issuing, state monitoring and program updating in an out-of-band mode. In software, the data plane data processing is realized by writing an fpga program, and the main functions of rule matching, host end application acceleration, data unloading and the like are realized. Meanwhile, an embedded linux system is used for control surface data processing, and functions of system upgrading, remote rule updating and the like are achieved; and a real-time operating system freeRTOS is used for monitoring the real-time state, so that the functions of real-time monitoring of the board card state, host-end BMC communication and the like are realized.
Referring to fig. 2, fig. 2 is a flowchart of a communication method of an intelligent network card according to an embodiment of the present disclosure.
The application also provides a communication method of the intelligent network card, based on the intelligent network card, comprising the following steps:
s101: receiving a data message through a data optical interface;
s102: dividing the data message into control plane flow and data plane flow by using a data separation module;
s103: and sending the control plane flow to an embedded linux system so that the embedded linux system identifies an IP core as a network card for communication.
When the intelligent network card is in communication, the data message is received through the data optical port, and then the data message is divided into control plane flow and data plane flow by the data separation module. Typically, the data separation module separates the data into control plane traffic and data plane traffic according to vlan-tag.
For the control surface traffic, the control surface traffic passes through the MCDMA module to the embedded linux system, and the embedded linux uses a driver to identify an IP core, i.e., the MCDMA module in fig. 1, as an MCDMA network card for bidirectional communication. The embedded linux system can acquire program version information from a remote data center through an IP core. Specifically, as shown in fig. 1, the embedded liunux application layer program acquires the latest matching rule and program version information from the data center at regular time through the MCDMA network card, uploads the status information, and issues the rule to the PL rule update module
And for the data plane traffic, the data plane traffic passes through an ACL rule filtering module, invalid network data which do not accord with the rule are filtered by using a blacklist, and the rest data are uploaded to a host server.
In a preferred embodiment, after passing through the ACL rule filtering module and before uploading to the host server, a specific application may be accelerated according to a data tag in the data plane traffic. Specifically, the application acceleration module may be utilized to select to accelerate a specific application to the PCIE port according to the data tag,
the data message enters the FPGA through an optical port and is divided into two paths of data of a control plane and a data plane through a data separation module: the control plane is transferred to Cortex-A53 through the MCDMA module, and the embedded linux running on the A53 processes data; and the data of the service surface is filtered by the ACL accurate matching module and is transmitted to the host by the PCIE of the DMA module.
Preferably, the freeRTOS system can be used for collecting the network flow information of the intelligent network card and monitoring the network flow information, namely the freeRTOS system is used for acquiring the BMC state information through the IIC interface and uploading the BMC state information to the embedded linux system.
The realization of the state monitoring function of the intelligent network card comprises the following steps:
(1) the Freetos system acquires BMC state information through an IIC interface;
(2) acquiring flow and monitoring information through information state acquisition of a PL (personal information provider) end;
(3) and uploading the BMC state information to the embedded liunux system in an inter-core communication mode.
