With that out of the way – I wanted to spend some time in this post talking about the command line tool found on Linux systems called
tc. We’ve talked abouttcbefore when we discussed creating some network/traffic simulated topologies and it worked awesome for that use case. If you recall from that earlier posttcis short for Traffic Control and allows users to configureqdiscs. Aqdiscis short for Queuing Discipline. I like to think of it as manipulating the Linux kernels packet scheduler.
