[c-nsp] Bandwidth Vs Number of Users

[Ziv Leyes]

Long time ago, when I used to manage modem baskets for dialup users I've used the statistic formula that says that you need a modem for every 8 users, and it worked like charm, but we're talking about the total of potential users, not simultaneous.
You can use the same formula for the bandwidth, given that 500 is the total number of potential users, and let's say you want to give them 16K each, then 500/8*16K= 1M, of course that the more you can give them the better.
BUT, if you know for sure that there will be 500 simultaneous users, then you're going to need 8-10M minimum, as the other guys suggested here before.

Also, you may consider filtering what do they actually need and what they don't and block all the unnecessary bandwidth consuming apps, such as streaming, and give them ONLY what they need, if it's possible, that will save you some bandwidth.
