Those are measured at the campus boundary. I don't have visibility inside
the school's network to know who much intra-campus traffic there may be .
but we know that peer-to-peer is a small percentage of overall Internet
traffic flows, and streaming video remains the largets.

Are your measurements taken at the campus boundary or within the campus
I remember the confusion when Centrex was first introduced at UMich. The
statistic there that confounded was call durations wildly exceeding models,
but mostly within the campus, not to the outside world. Could there be peer
to peer traffic that you do not see?

The download/upload in our residential/business eyeball network has been
trending a 95th-percentile based ratio of 9:1. If I look at a higher-ed
customer of ours who has symmetric service and has a young demographic the
average ratio is 11:1 and the peak ratio 8.8:1. So despite access to
symmetric speeds, they're not showing a distinctively heavier symmetricity.
