Page 10 of the presentation on the link you provided says those are the numbers they recommend "for the next 5-7 years". Perhaps they meant to say "in 5 to 7 years"? "for the next 2-3 years" they recommend 10 Mbps per 1,000 people to an ISP and 100 Mbps per 1,000 people between schools. Our campus is already using almost 3 times the ISP bandwidth recommended "for the next 2-3 years". If we take our current ISP bandwidth and increase it by 50% every year for 5 years it would be about twice the 100 Mbps per 1,000 students/staff recommendation. --- Bruce Curtis [email protected] Certified NetAnalyst II 701-231-8527 North Dakota State University
