Problems solved by technology
It is impossible to test the network performance, involving many test commands, the test commands are complicated, and it is easy to cause test errors. After the test, the results of each thread need to be checked one by one, and the total network performance cannot be obtained, and this test method is inefficient.

[0083] First use the command netserver to start the server program on a machine 1, and then execute the test command on the machine 2 to be tested for testing. Machine 1 and machine 2 are connected through a network cable. Here, it is assumed that the ip address of machine 1 is 1.1.1.3, and the ip address of machine 2 is 1.1.1.2.
[0084] Here machine 1 can be a test node, and machine 2 can be a computing node.
[0085] Take the performance test of 64k data blocks as an example, the test command is: 1.1.1.3-l 1800---m 64k
[0086] Because machine 2 is to be tested by sending data to machine 1, the variable ip is used here to record the ip of machine 1.
[0087] ip="1.1.1.3"
[0088] #Use a for loop to traverse the data blocks to be tested, and different data blocks ["64k","128k","256k","512k","1024k","1280k","1518k"] will be assigned to variables bs, and use each value to execute the code after the for loop.
[0089] for bs in["64k","128k","256k","512k","1024k","1280k","15...

The invention provides a system and a method for automatically testing the performance of a network card. The method comprises the following steps that a computing node sends a data block to a test node based on a control instruction sent by a test module; the computing node receives data block received information and receiving time point information of the data block sent by the test node, and simultaneously sends a third data block to the test node and records a sending time point and so on until all the data blocks configured by the computing node are sent out; and after all the data blocks are sent, the computing node sends the capacity, the number, the sending time points and test node receiving time points of the data blocks to the test module for storage. The time spent in manual operation is reduced in a testing process, compared with the time spent in manual operation in time, the operation accuracy is greatly improved, and the test working efficiency and accuracy are greatlyimproved.
Description
technical field [0001] The invention relates to the field of network testing, in particular to a system and method for automatically testing the performance of a network card. Background technique [0002] The network card performance test is to verify the performance data of the network card in the machine. By comparing the test results with the theoretical bandwidth of the network card, it can be judged whether the network card can exert its maximum performance on the machine. The industry often uses neteperf when testing network card performance. Netperf is a very common tool for measuring network bandwidth. It can set data blocks of different sizes to test whether the performance of network cards under different data blocks is consistent. However, this network card cannot open multiple threads. The performance of a single thread on a network card with a bandwidth exceeding 25G exceeds the bottleneck, and the real maximum performance of the network card cannot be tested. ...
