It's easy if you understand it :) In your case rate = 20kbit, ceil = 2mbit. And you need 100 classes of these connected to a class with ceil = rate = 2mbit and you are done. I have some basic scripts on www.docum.org. Or you can try my configurator at http://home.docum.org/qos/ to get an idea about how you can create a htb script. Maybe you can try ESFQ. It's an enhanced SFQ. It will create for each flow it sees a new band. A flow can be determined by a combination src/dst port/ip. I have more info on the faq page on www.doucm.org. Each flow has the same opportunity to send something. Stef -- stef.coene@xxxxxxxxx "Using Linux as bandwidth manager" http://www.docum.org/ #lartc @ irc.oftc.net
