[LARTC] HTB: quantum vs. burst

Linux Advanced Routing and Traffic Control

Hello,

a quick question: what exactly is the difference between quantum and
burst in HTB?

Original HTB documentation states the following with respect to
quantums:

"... when more classes want to borrow bandwidth they are each given some
number of bytes before serving other competing class. This number is
called quantum."

Burst is defined like this:

"The burst and cburst parameters control the amount of data that can be
sent at the maximum (hardware) speed without trying to serve another
class."


>From the quotes, the purpose of quantums and both burst parameters seem
to be somewhat related, one might say overlapping.  Is it that quantums
apply in different situations than bursts?  If so, when is each of
quantum, burst and cburst applicable?

TIA,

	pvl
