On the short term, traffic can be bursty for the different classes, but each one will belimited to 8kbit. But on the long term, each class will get the same share of bandwidth. ------ basicaly this may work if difference is not big, but it was not working for me, I was trying to set rate 8kbit for everyone, since the sum of rates was 3 times biger than parent ceil, trafic was divided in unpredictable way. then I set rate to 1 kbit and everything worked well filling syslog by warnings that quantum is too small. logicaly this should not work because htb guarantee the rate amount trafic, so what if there is not so much available? > > Q5.

I'm not sure but, isn't quanum only used for leaf classes? So the quantum of parent classes doesn't mather ? --------- You may be right, since I did not checked source code for this, but logicaly quantum is very significant part and shoud work everywhere, I suppose quantum is about same as cburst, but even more significant, sems it is only way to divide bandwitch between classes with some proportion. ----------------- I found strange limitation, if class have leafs, then I cant attach sfq to it. where will go unclasified packets from that class? Into root's default? Now I use dummy class for this purpose with filter which match on anything Strange that htb have such limitation.
