RE: Current trends in capacity planning and oversubscription

[John van Oppen <jvanoppen () spectrumnet us>]

I am on the technology committee of the college I attended (Whitman) and they currently have a 200 mbit/sec via gigE 
link for a campus of just under 2000 and every building has at least 1X gigE into their backbone.    They are in a 
rural area (walla walla, wa) but they don't generally have more than 100 or 150 mbit/sec of usage, fitting nicely in 
the below recommendations.
