I'll make a quick answer in the hopes that someone on the list will provide
a better one.
> 1) =91Bursty=92 is a word with no agreed meaning. How do you define a burst=
I don't know of a widely agreed upon definition. Generally when people say
"bursty" traffic they mean non-isochronous traffic -- namely traffic where
transmissions are not evenly spaced.
Personally I try to push that definition a little further and say that
"burst Poisson" isn't truly bursty either. That's because we've known
since the early 1980s (and finally understood why when we saw the
self-similarity paper of 1993) that "burst Poisson" doesn't capture the
complexity of bursty traffic we see in networks.

I don't do data center traffic analysis (indeed, getting good data is hard),
but they certainly see (non-Poisson) bursty traffic.
Good luck with your research!
