Comcast will be an ISP, and they dont own the pipe. But they have such a huge customer base they should not have a problem negotiating an excellent rate with the back bone provider.]]> http://www.dslreports.com/forum/Re-Do-the-math-2080226 Wed, 26 Dec 2001 14:26:14 EDT http://www.dslreports.com/forum/Re-Do-the-math-2054933 http://www.dslreports.com/forum/Re-Do-the-math-2054933 Sat, 22 Dec 2001 01:05:38 EDT http://www.dslreports.com/forum/Re-Do-the-math-2054914 While your math is excellent, your assumptions are incorrect. In order for your numbers to work the volume of traffic would need to be the same all of the time. ISP's would love it if traffic was perfectly flat 7x24. The flatter it gets, the lower our costs.

Unfortunately that's not how we get billed. We get billed on the spikes, it's called the 95th Percentile...

Basically, we get billed on what size pipe it would take to handle all of our traffic without dropping packets at its 95% highest point in a one month period.]]> http://www.dslreports.com/forum/Re-Do-the-math-2054914 Sat, 22 Dec 2001 01:03:43 EDT http://www.dslreports.com/forum/Re-Do-the-math-2054716 http://www.dslreports.com/forum/Re-Do-the-math-2054716 Sat, 22 Dec 2001 00:23:07 EDT http://www.dslreports.com/forum/Do-the-math-2050341
Assumptions:
T3 at 45 Mbps costs $22,000 per month (at least last time I priced them in Summer 2000)
Base $49.95 monthly charge is enough to cover equipment and personnel costs (since they weren't charging throughput before).

First we have to figure out how much throughput that line is capable of, so we take
3600 seconds in an hour, 24 hours, 30 days
Gives us 2,592,000 seconds per month.
Multiply this times 45 Mb gives us 116,640,000 Mb of possible throughput. Convert it to Bytes gives us 14,580,000 MB of data throughput.

To figure out the cost per MB, we divide the throughput into our cost of $22,000 per month.

The result is $0.0015 / MB.
1024 MB in a GB, so a GB costs them $1.54.

Fun with numbers huh! And you know they have bigger pipes than T3 and the economies of scale keep getting better in their favor. What does the number look like at OC-6 or OC-12? Anyone know how much those cost per month?
