Referring to FIG. 1, it is an operational environment diagram of a preferred embodiment of the network data traffic testing system of the present invention. The network data flow test system 10 runs on a server 1, which includes a Baseboard Management Controller (BMC) 12, a network card 14, and a multiplex electronic switch 16.

The BMC 12 is a control management chip built in the main board of the server 1. The chip supports an Intelligent Platform Management Interface (IPMI) specification, which describes management functions that have been built into the motherboard. Features include: local and remote diagnostics, console support, configuration management, hardware management, and troubleshooting.

The BMC 12 further includes a storage 120 and a processor 130. The storage device 120 is configured to store data such as a root code of the network data flow testing system 10, and the processor 130 is configured to execute a root program of the network data traffic testing system 10.

The network card 14 is a network component working in the physical layer, and is an interface connecting the server 1 and the transmission medium in the local area network, which can not only realize the physical connection and the electrical signal matching between the server 1 and the local area network transmission medium, but also realize Frame transmission and reception, frame encapsulation and decapsulation, media access control, data encoding and decoding, and data caching functions. In this embodiment, the network card 14 includes a plurality of (for example, two) network cards 140.

The multiplexed electronic switch 16 is located between the BMC 12 and the plurality of network cards 140 of the network card 14 (see FIG. 4) for connecting the plurality of network cards 140 of the server 1 to the BMC 12 in a certain order. To test the flow of network data flowing through each network card.

In this embodiment, the network data flow testing system 10 can be divided into one or more modules, and the one or more modules are configured to be one or more processors (this embodiment is a The processor 130) executes to complete the present invention. For example, as shown in FIG. 2, the network data flow test system 10 is divided into a switch module 100, an acquisition module 102, an analysis module 104, a statistics module 106, a display module 108, and a determination module 110. The module referred to in the present invention is a program segment for performing a specific function, and is more suitable for describing the execution process of the software in the server 1 than the program. For the function of each module, refer to the description of FIG.

Referring to FIG. 3, it is a flow chart of a preferred embodiment of the network data flow testing method of the present invention.

In step S10, the switching module 100 controls the multiplex electronic switch 16 to sequentially connect each of the plurality of network cards 140 of the server 1 to the BMC 12 in accordance with a preset sequence to test the flow of each network card. 140 network data traffic.

In this embodiment, the preset sequence may be an order of numbers set in advance for the plurality of network cards 140. For example, the number of the network cards 140 is three, and the numbers of the three network cards 140 are arranged in ascending order. It is N1, N2, and N3 (see Figure 4).

The network packet flowing through the currently connected network card 140.

In step S12, the parsing module 104 parses the obtained network data packet to obtain an application layer data packet. The network data packet is added with a data header during the transmission process through the link layer, the network layer, and the transport layer. This process is called encapsulation. The parsing of the data packet is to parse the encapsulated network data packet. The data header of the layer is removed, and finally the application layer data package is obtained. In this embodiment, the obtained network data packet can be parsed by using the TCP/IP protocol to obtain an application layer data packet.

In step S13, the statistics module 106 obtains the number of application layer data packets and each application layer data according to the test period (the test period is a preset time for testing each network card 140, such as 10 seconds). The data traffic contained in the packet counts the network data traffic flowing through the currently connected network 140.

The start time and end time of the time period and the number of application layer packets that are obtained through the currently connected network card 140.

In step S15, the determining module 110 determines whether all the network cards 140 have been tested. If the test is completed, the process ends, otherwise, the process returns to step S10.

Steps S10 to S15 sequentially connect the plurality of network cards 140 to the BMC 12 through the multiplex electronic switch 16, and acquire and parse the network data packets flowing through each of the network cards 140, and further statistics flow through each of the network cards 140. The network data traffic avoids the waste of a lot of manpower and resources when using routers to count network data traffic in a multi-NIC environment.

It should be noted that the above embodiments are only for explaining the technical solutions of the present invention and are not intended to be limiting, and the present invention will be described in detail with reference to the preferred embodiments. Modifications or equivalents are made without departing from the spirit and scope of the invention.
