First of all although I personally also think cisco's are not very good for other things than routing, experience tells me that problems are often caused by misconfiguration. I'd check out with an experienced cisco professional. >The question: are we correct, I mean is qdisc+htb the right thing to >be used in such a scenario? Has anyone out there seen a linux box >handling so many networks? I expect you want to use many htb classes with the same parent. I have seen a reports that this causes problems when you really have a large class number (several hundred), but again, this may have been caused by misconfiguration. If you adapt your requirements however (every IP is handled equally), you can use WRR, it has been proven to work without problems under even larger number of clients (1400) and bandwidth (16Mbit). For an example see here: http://mailman.ds9a.nl/pipermail/lartc/2005q2/016500.html If you don't want to adapt, once upon a time I wrote a management tool for an ISP with requirements similar to yours. Although I tuned it for performance and it seems to work well, as far as I know there are only a couple of dozen users, I don't know how it would behave if it was used with several hunderd users. >AL Yours sincerely, Peter _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
