no publised, but from my real-world router:

57.7% are 64 bytes. Sampling of over 448 million (1/2 billion) packets. 1
day, 3 hour sample. Interesting/neat spike at 576 and 1536.

Anyone know of any studies documenting this?  A know that IP packets
over the Internet tend to be smaller rather than larger, but I wondered
if anyone has published something.
