Question about htb class

Linux Advanced Routing and Traffic Control

Hi everyone.

I'm new to this list and I have some questions
regarding HTB class.
I was trying to see how tc sets the parameters for
HTB, but really couldnt understand them.
So, I thought that I might ask the wizards.
It's mainly from the source code.

1. What is the cell_log ?
(its everywhere in the code)

2. Why does htb calculate its burst(buffer) with
tc_xmit_time() ? Is opt.rate.buffer supposed to 
have the time it takes to transmit the packet ?
(in q_htb.c around 223 lines)

3. What does rtab and ctab arrays do ?
And what kind of value should be in there ?
(its set in tc_core.c tc_calc_rtable())

I'd really appreciate your help.
Thankyou very much in advance.

Eme
