Ctokens is used for the ceil, tokens is used for the rate.  tokens are used to 
give a class a minimum bandwidth and ctokens are used to give the class a 
maximum bandwidth.

For ctokens the ceil parameter is used, for tokens the rate parameter.

What do you mean with this ?

Thank you.

Before that ... do ctokens and tokens have an equal
capacity to transfer a packet; meaning can exactly one
packet flow through, as long as, for every single
ctoken or token?
If this is true, then my question ... would a child
class borrowing a token from the parent class treat a
ctoken and a token equally? Meaning, are ctokens &
tokens qualitatively the same and different only in
the fact that ctokens are used at ceil rate and at
normal rate a token is used?

I am sorry if I am confusing you, but I am terribly
confused, and I am just trying to understand things
better :)

Thank you.

Regards,
suraj.

1 (c)token = 1 packet.  So you can only send a packet when you have a token.

Euh.  Yes.

I also have think hard about your questions :)  And that hurts after sitting 
3hrs in a traffic jam.
