<html><body><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt">When we did this a while ago now, we took a guess on the low side and then started moving connections across (from L3 to L2). As we did this we kept an eye on bandwidth usage and when it looked like it was getting too low, increased it before the next batch of moves.<br><br>This may not be possible though, if you can't do the moves a few at a time or your provider isn't flexible enough to let you wind up the bandwidth as you need it. try and work with your wholesale provider and see if they're willing to help you out on this.<br><br>As others have said it doesn't really matter what the total data usage is, you need a big enough pipe to cover your peak bandwidth consumption (which will vary depending on your customer base). If you don't have enough to cover the peaks then you will have congestion and this may provide an adverse
experience for your users. The alternative is that you don't worry about having enough bandwidth for peak periods and just have enough for "average" usage and let the users tough it out. Really depends on who you are and what you are trying to say to your user base.<br><br><br>regards,<br>Tony.<br><br><div><span><br></span></div><div><br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; margin-top: 5px; padding-left: 5px;"> <div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"> <div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"> <div dir="ltr"> <hr size="1"> <font face="Arial" size="2"> <b><span style="font-weight:bold;">From:</span></b> Joseph Goldman <joe@apcs.com.au><br> <b><span style="font-weight: bold;">To:</span></b> Samantha Scafe <samantha@smellyblackdog.com.au>; AusNOG@lists.ausnog.net <br> <b><span style="font-weight:

--></style><div><div dir="ltr">It'd be too hard to apply an overall formula to this, it is dependent on your users. Businesses can tend to use a lot of data but very little off peak, same as gamers and leechers but all times of day , but then you could have very easy mum and dad users that barely use 10% of their quota. <br>
Also then with a L2 set up you need to make sure that you have enough at your highest peak throughput, not enough over an average of the month, else battle the congestion problems. </div>
<div dir="ltr">The best thing to do is to extrapolate off your current customers data, if your provider can offer an aggregate bandwidth graph of your L3 users <u>that</u> will give you an idea of peak usage, and use quota level data to determine, on average across your user base, how much they actually use of their quota in %, and base your pricing on that. </div>
