Hello all, I have a question about the details of HTB packet dequeuing and the effect on scheduling of packets queued in different classes. I have been unable to answer this question with certainty either by reading the HTB user guide [1] or the LARTC FAQ on docum.org [2]. The closest I can come to guessing the answer is the section on burst in the HTB user guide [3]. Here's my question: When a sending class is below rate, how many bytes is the class allowed to transmit before another class is serviced? It seems clear to me from this answer [4] in the LARTC FAQ, that the quantum is used to allow each class to borrow from a parent in a turn. Is the class also allowed to dequeue only quantum bytes per turn (when above rate but below ceil)? But, more importantly, when a class is below rate, is it allowed to dequeue a maximum of burst packets per turn? Is this statement, then, accurate? - below rate, a class can dequeue up to burst bytes per turn - above rate, a class can dequeue up to quantum bytes per turn Thanks for any replies, -Martin [1] http://luxik.cdi.cz/~devik/qos/htb/manual/userg.htm [2] http://www.docum.org/stef.coene/qos/faq/cache/ [3] http://luxik.cdi.cz/~devik/qos/htb/manual/userg.htm#burst [4] http://www.docum.org/stef.coene/qos/faq/cache/31.html P.S.
