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 about
tcbefore when we discussed creating some network/traffic simulated topologies and it worked awesome for that use case. If you recall from that earlier post
tcis short for Traffic Control and allows users to configure
qdiscis short for Queuing Discipline. I like to think of it as manipulating the Linux kernels packet scheduler.
