How many zeroes are there? If you got rid of them, a log transformation might
help you. Also, have you considered looking at the distribution of the times
between packets (or bytes)?? There are some interesting theoretical models
for the distributions of times between packets. I've got a few books on the
subject, but they're at home. E-mail me off list if you're interested.
