Avg. Packet Size - Again?

[sah.list at gmail.com (Sean Hafeez)]

Most of the data and studies I have found on this topic are a bit out  
of date.

I would be interested in find out what the average packet size people  
are seeing on their backbones is at this point and time? Also for  
those in the DC space what is average packet size you are seeing for  
web farm traffic (outbound)? Yes I know there are 1000's of answers  
and different possibilities in setups so please no, "this is a dumb  
question". I am well aware of all the variables involved in this. I am  
just looking for some data points that come from a wide degree of  
sources.

Is this data even something that you track and if so why?

Thanks!
Sean
