Most up to date packet size distribution info

[Rob Healey]

Hi,

        I was wondering what the best sources for up to date info on current
        packet size distribution on the Internet might be?

        i.e. X% of Internet packets are of size Y bytes to Z bytes.

        I remember seeing this 2+ years ago but that was many disk
        failures/backup fiascos ago...

        Thanks!
