I will investigate further I guess I'm still missing the point. Isn't my _effective_ bandwidth still entirely dependent on how big my PPP encapsulated packets are just prior to being broken into streams of 53 byte ATM cells? With the patch does HTB behave appropriately if it gets hit with mostly ~ 100 byte packets where you'd encounter around 30% of your ATM rate lost due to the overhead of null byte padding? > Ed W _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
