I've seen this referred on the list before (I assume by you ;)), but
haven't really grok'ed it before. I like the delta-Q measure as a way of
thinking about overall network performance; and there's definitely
parallels to thinking about the end-to-end 'latency budget', which I
also find quite instructive (I think I it picked up from Joe Touch at
some point).

How do you deal with the fact that loss and delay can be exchanged for
each other (via retransmissions)?

Also, which publication would you recommend if I'm interested in
specifically how you 'Mathematically model behaviour and delta-Q' as you
mention in that slide set? :)
