[e2e] simulation using self-similar traffic

[Mark Crovella]

Bill - No screw-up there, that's indeed what typically happens.

Soo-hyeong & Polly,

If you take the conversation off-line, please share with the list any
conclusions
that you come to. I, for one, would be very interested.

My limited experience with heavy-tailed distributions has always been less
than
satisfactory. I think that because the probability that very long file sizes
will
be drawn is so low (though non-negligible), the sample average file size is
almost
always less than the true average of the distribution. The result I get is
that
the simulated offered traffic is less than the expected offered traffic,
and,
ironically, performance ends up looking better than expected rather than
worse.

Or it could be that I screwed something up. :-)

Regards,
Bill
