The FEC technology refers to a technology that, before a signal is sent to a transmission channel, a coding process is performed in advance according to a certain algorithm, a redundancy code with a characteristic of the signal is added, and a receiving end decodes the received signal according to a corresponding algorithm, so as to find out an Error code generated in the transmission process and correct the Error code, that is, a technology capable of reducing BER (Bit Error Ratio) of the signal received by the receiving end.
At present, a special instrument is used to perform network performance test, such as an N4891a400GBASE FEC interactive physical layer receiver test solution, which can characterize and quantitatively evaluate the actual BER (Bit Error Ratio) and FEC performance of a silicon communication device. However, this solution relies on special instruments and equipment, which is less versatile, and therefore it is necessary to propose effective technical means to solve this problem.

Optionally, if the FEC performance of the target test network is tested, the preset threshold is determined according to the type of the network card, for example, the preset threshold corresponding to the 25G network card is 250, the preset threshold corresponding to the 100G (4×25G) network card is 1000, and the preset threshold corresponding to the 100G (2×50G) network card is 100000.

(1) For FEC performance testing:
step S1, a first mode setting instruction is sent to a switch in a target test network, the first mode setting instruction is used for instructing the switch to set the FEC modes of a first port and a second port to be FEC on mode,
Step S2, the first server and the second server respectively send verification instructions, and the verification instructions are used for indicating the first server and the second server to respectively output negotiation results after auto-negotiation with the switch.
Step S3, after the negotiation result indicates that the first server and the second server auto-negotiate to the FEC starting mode of the first port and the second port, a test instruction carrying test duration is sent to the first server, and the test instruction carrying test duration is used for indicating the first server to continuously send test data to the second server in the test duration through the switch.
And S4, receiving the number of CRC errors output by the second server based on the test data, if the number of CRC errors is 0, the FEC performance of the target test network passes the test, otherwise, the test fails.
(2) For network card transmission performance test:
step S1, a second mode setting instruction is sent to a switch in the target test network, the second mode setting instruction is used for instructing the switch to set the FEC mode of the first port and the second port to be an FEC closing mode,
step S2, the first server and the second server respectively send verification instructions, and the verification instructions are used for indicating the first server and the second server to respectively output negotiation results after auto-negotiation with the switch.
Step S3, after the negotiation result indicates that the first server and the second server auto-negotiate to the FEC closing mode of the first port and the second port, a test instruction carrying test duration is sent to the first server, and the test instruction carrying test duration is used for indicating the first server to continuously send test data to the second server in the test duration through the switch.
And S4, receiving the CRC error number output by the second server based on the test data, and if the CRC error number is smaller than a preset threshold, the network card transmission performance of the target test network passes the test, otherwise, the test fails, wherein the preset threshold is determined according to the type of the network card.
The application can realize FEC performance test by sending the first mode setting instruction and the test instruction to the target test network, and can realize network card transmission performance test by sending the second mode setting instruction and the test instruction.
