This article mainly introduces "delay and packet loss simulation of Linux application". In daily operation, I believe that many people have doubts about the delay and packet loss simulation of Linux application. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "delay and packet loss simulation of Linux application". Next, please follow the editor to study!

The most basic use of tc

Tc qdisc show # shows tc qdisc add dev eth0 root. # join tc qdisc change dev eth0 root. # modify the existing qdisc, remember, after adding the same item, you can only use change to modify the tc qdisc del dev eth0 root # Delete the delay simulation in Linux.

Set a delay of 3s:

Tc qdisc add dev eth0 root netem delay 3000ms

You can add a delay after 3000ms, such as' 3000ms 200ms' for 3000ms ±200ms, with a delay range of 2800-3200.

The results are shown as follows

Simulation of packet loss in Linux

Set 50% packet loss:

Tc qdisc change dev eth0 root netem loss 50%

If the packet loss rate of the following 50% is changed to'50% 80%', this is different from the delay above, which means that the packet loss ratio is between 50% and 80%.

Display as follows

Original: delay and packet loss simulation in testing in the application of Linux

At this point, the study of "delay and packet loss simulation of Linux applications" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
