Oh, thanks. Yes, I think that I understand the intuition
behind those claims.
I was looking for more detains about the mathematical side of
the things (e.g., what is the measure of "hurt", in your words
or the cost to which Dan refers?) and like why the optimal
retry schedule is essentially independent of the actual
distribution of message delay times. And why did Dan choose a
quadratic retry schedule and not, say, a cubic one? For some
convenience?
If Dan (or any other poster) could help, I'd be very gateful.
:-)
Thanks for your insight, Roger...
