To show that I am not pulling this out of my hat check out this URL for a Sprint evaluation of over 7 TB of broadband customer data.

VoIP and HTTP acknowledgements (syns and acks) are typical examples for traffic under 512-byte in size.

I am not denying that larger packet sizes make a good chunk of the traffic, but especially looking at upstream traffic things look a little different.

So, since Internet traffic is so diverse, I think it does not make sense to base any evaluation on one single packet size.
