Prioritization...

Got a question - been trying to track some loss I've seen in our traffic - and one of the things that came to mind was packet priority and a lower priority being set for UDP at some exchanges - especially congested ones. Anyone here doing such - snd if so does anyone have anysort of data re: how much of that traffic is being dropped... -- I am nothing if not net-Q! - ras@poppa.clubrich.tiac.net
