Hi Lianwen,

Thanks for suggestion, do you have some test-cases in mind? You are
welcome to post the patches too :)

In general, I think you could setup something outside LTP, for example,
change qdisc on the test interfaces, etc.

Currently, only dctcp test is using 'tc netem' and I'm currently planning
to add BBR congestion-control algorithm tests there, also using netem
module.

Also, there are tests in Linux kernel:

Thanks,
Alexey
