I was fooling around with low cost (and functional) alternatives to netflow. Using some of the cef per-prefix accounting, I came up with some average packet sizes per-as. I do not know if other pieces of software provide this, but it was interesting to me given the recent debate over traffic/political network engineering. Note: These ASs were chosen because I was looking at aads. Also, some of the average packet sizes (specifically for the universities) are skewed because of small sample size. This data was taken over ~ 3 week period.
