Hi everyone,

I'm a student at NC State University, and I'm working on a project to
implement some new classful AQM algorithms and test their
effectiveness. However, I'm getting hung up on how to get the new
algorithm set up in the kernel.

From what I've looked at, it looks like I need to add my code to
/net/sched/, and edit both the Kconfig and the Makefile to be able to
add my code as another module.

Basically yes, take a look at:

Finally, in order to use the new scheduler, I need to select it using
the tc command. What do I need to do to add my algorithm to the tc
command options?

Read the existing qdisc's in tc, for example:
http://git.kernel.org/cgit/linux/kernel/git/shemminger/iproute2.git/tree/tc/q_fq.c

That all makes a lot of sense. What do I need to do to apply these
patches on a live system? I have access to a network made of virtual
machines with standard Ubuntu 14.04, to which I have SSH access.
There's no way for me to upload a different image to use.
