Description

A system and method for automatically testing network card performance

technical field

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

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.

The existing technical solution is to manually input commands when testing different data blocks, and then input the next command after the test is completed, so as to complete all the tests manually. It is impossible to test the network performance, which involves many test commands, which are complicated and easy to cause test errors. After the test, the results of each thread need to be checked one by one, so the total network performance cannot be obtained, and this test method is inefficient.

In order to further illustrate the inventive concept of the present invention, the present invention provides a specific embodiment:

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.

Here machine 1 can be a test node, and machine 2 can be a computing node.

Take the performance test of 64k data blocks as an example, the test command is: 1.1.1.3-l 1800---m 64k

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.

ip="1.1.1.3"

#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.

for bs in["64k","128k","256k","512k","1024k","1280k","1518k"]:

#Write a command that can be executed under the system and save it in the variable cmd. The function is as follows. The content of the command is to use the for loop to open 4 netperf programs, and the 4 programs perform the test with the bandwidth of bs at the same time. It takes 1800 seconds. The test results are saved to the bs_$i.log file, where bs is the bandwidth of the current test, and $i indicates the current number of threads;

cmd="for i in{0..4}; do netperf -H"+ip+"-l 1800"+"---m"+bs+"|tee"+bs+"_$i.log&;done"

#Execute the command saved by cmd

work=subprocess.call(cmd,shell=True)

#Make the program wait for netperf's test execution to complete

time. sleep(3)

time. sleep(1800)

#After the netperf test is completed, write the system command ls"+bs+"_performance* to extract the result file name after the previous netperf test and save it in the variable cmd

cmd="ls"+bs+"_performance*"

#Execute the command saved by cmd

work=subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE)

work. wait()

#Save the execution result of the above command to the variable filegroup

filegroup=work.stdout.readlines()

sum_result=0.0

#Use the variable file1 to traverse the variable filegroup

for file1 in filegroup:

file1 = file1. strip()

#Write a system command and save it in the variable cmd. The function of the command is to extract the test results from the content of each file through keywords;

cmd="cat"+file1+"|grep"+str(self.performancetime)+"|awk'{print$5}'"

#Execute the above command work=subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE)

strresult = work.stdout.readlines()[0]

#Save the result returned by the command to the variable result

result=double(strresult. strip())

#Add the result to sum_result

sum_result+=result

#After traversing the filegroup, the results of all threads are added to the variable sum_result, and the value of the variable sum_result is written to the file, that is, the performance test of the current block is completed.

file(bs+"_performance_total.log",'w').write(str(sum_result))

After the test is completed, you can view the bs_performance_total.log in the current folder to view the sum of the test results of multiple threads under the bandwidth, which is the result of the network card performance test.
