The difference is the people using LHC data usually have someone who can
figure out network capacity planning, while the people in an
administrative school office may not have anyone.
So what is a reasonable network capacity for 1,000

Just as LHC people and a school are different, I'm willing to bet that

people said 100%

While the answer is always it depends, I was wondering what the current
rules of thumb university network engineers are using for capacity
planning and oversubscription for resnets and admin networks?

- An external Internet connection to the Internet Service Provider of at
least 100 Mbps per 1,000 students/staff
30K students here, 2x10GE to the outside world.
- Internal wide area network connections from the district to each

mbit/sec of usage, fitting nicely in the below recommendations.

I would say that's highly dependent on your geographical location. In Montana I
could see that as being true, but not in NYC, for

Sometimes it is a hard sell, but the factor most overlooked when
designing high speed networks is that of designing for low latency.
Bandwidth and over/under subscription are only part of the network
design. Low latency networks (regional RTTs of 1-5 milliseconds; campus
RTTs in the sub
