The setup I gave was purely hypothetical. 300kbit headroom sounds way to high to me as well - any advice others may have on this would be appreciated. > Another way of indirect headroom would be to hard limit the Web class, > i.e. give the Web class a lower ceil than the other classes.

In hindsight it seems so obvious I don't know why I didn't think of it myself. Thanks for taking the time to answer my query. _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
