Re: [PLUG] bandwidth calcuations


A) how can you calculate this so you don't get a big surprise bill? I wanted to use my current T1 to baseline. So if I were to peak my T1 100% all month, how much usage would that be. I have a a pretty good idea of how much traffic I have now - so maybe a could figure out how much i'll need for growth.

B) who is your colo with? I'm investigating providers

A big part of this question depends on how the bandwidth is calculated.  For instance, some colos charge for transfer.  Ie, you can transfer up to 2 gigabytes per month over our lines, regardless of whether you do it all in one day or slowly over the 30.  Other colos, such as the one I'm using, charge for bandwidth using the 95/5 rule.  I pay for a 1 Mbps stream every month, but the connection has a top speed of 10 Mbps.  At the end of the month, they take the highest 5% of my traffic, disregard it, and charge me for the average bandwidth used by the lowest 95%.  I then get charged for every Mbps I go over the amount purchased, which is much more expensive than purchasing a 10 Mbps connection.

HTH,

Well, what's your existing pipe? Your ISP probably specifies it in bits per
second. In which case:

monthly use (Megabytes)= (bits-per-second/8) * 60 * 60 * 24 * 30 / 1048576
