how to add my own traffic scheduler to TC

What are the steps needed to add my own traffic scheduler to TC?

My understanding is that I need to do something in the net/sched/
directory: add a schedular eg sch_blue.c, change the Makefile, config.in
and sch_api.c; add the appropriate qopt, xstats struct... in the
include/linux/pkt_sched.h. I've got it all compiled without warnings or
error. When I typed "tc add dev eth0 root blue limit 1000kB......", it
complained "Unknown qdisc "blue", hence option "limit" is unparsable".
When I typed "tc add dev eth0 root red limit 1000kB.....", it worked
fine (of course).

The code I wrote was a complete copy of the sch_red.c, with text changed
to blue instead of red. TC is not happy with my blue scheduler. What
have I done wrong? Have I missed something?

Linux Kernel version 2.4.20-8

Many Thanks,
Kennedy
