Hi all, I patch my kernel (2.6.17) and my tc (iproute2-2.6.18-061002) utilitie for an accurate packet scheduling on an ATM link. I configure my HTB hierarchy on the upload of the link and try with differents flows. It works correctly but in some of case I lose about 50% of my bandwith. I use the overhead (42) configuration for my link (PPPoE, VC/LLC) indicate in the documentation. My question is, how this hoverhead value is calculate ? I try to separate the streams with the lentgh of the packet in differents classes and put a specific overhead for each one, but I don''t know how calculate it. Do you think it''s a good solution ? Is it necessary to put the atm, nohyst options and configure the overhead for the mother class ? Thanks, Edouard. _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
