Re: Doubtful Comcast will ever release the bandwidth meter
said by sturmvogel:Is 2-3GB what they claim as typical? That seems low to me. But why should that matter? When users all see they are at even 50GB, the 250GB cap wont be an issue (except for those planning to change usage, by signing up for legal movie streaming, ouch)
Maybe after looking more at the data that "average" 2-3 GB usage/mo turned out to be higher and they are concerned that if people would have a way to easily monitor the usage, all that stark contrast between the 2-3 GB and 251 GB "hogs" would not have the desired effect ?

They claim 1-2% of the pipe capacity.
It's actually fairly accurate. Ask any ISP.
We've done this math before, but for fun let's go with a 12/2 line, 14Mbps total, or 14Mb*60*60*24*30=4.3258667 terabytes total bandwidth capacity.
Take 1% of that...
14 Mb * 60 * 60 * 24 * 30 * .01 = 44.296875 gigabytes
and there you go.
The oversubscribed model is based on providing enough capacity for 1-2% usage across all users.
Given Comcast has a stated cap of 250GB - closer to 7% - they may actually be using a 5-10% oversubscribed model.
A nice article (it even mentions Comcast!) that explains the reality of the business is
quote:Or, 1-2% usage.
Consumer broadband services are usually priced based on their peak download bit rate. A DSL service might be good for 3 Mbps, a cable modem set to 6 Mbps, and a fiber-to-the-home service rated at 50 Mbps. The ratio of peak to average rate is known as the oversubscription ratio. This ratio can be very high in practice. Today, a typical consumers average usage might be in the 50 kbps range. (Thats about an order of magnitude higher than the average dial-up modem users usage.) So the oversubscription ratio could well be over 50 or even 100 to one! That has a big impact on the retail ISPs costs.

and thats just on the low tier
then ramp on upto 50/10
but then figure the capasity of an 8ch line
127.3040771484375 Terabytes permonth
that means is everyone on a node had an 8ch modem but was only on the 16/2 tier then
22.888888888888888888888888888889 users could go full speed all the time
or 6.8666666666666666666666666666667 users on the 50/10 plan could go fullspeed all the time
