Calculate the bandwidth needed for my organization

I'm working for an Academic institution with about 600 researchers, 2000 students and 1000 administrative personnel.

How can I calculate the bandwidth needed to ensure fast and reliable access to the internet?

This is considering normal access to the web (html, flash, youtube, downloads, etc).

I'm currently in the process of renewing the contract with our ISP, so any help would be greatly appreciated.

Thanks in advance

Is good, but I need calculate the bandwidth needed for a number of users to access internet. I'm not hosting any application.

Of course I am thinking in installing a huge link to the web to measure the real use of the internet. Nevertheless I am looking for a formula to calculate the needed bandwidth based on the number of users, total dialy bandwidth per user, pick hour, etc.

The problem that I have are not the variables because I have them. The problem is that the network usage is not linear but logarithmic (or something like that), I mean is not an arithmetic calculation (BandwithUser1+BandwidthUser2+Etc) because it has to consider the voids between requests.

Is there a way to calculate this?

ok, I guess that I'll have to estimate it with try & error.
