Do any of you have any pointers on how to go about predicting usage for high-speed ethernet access?
Finally, what do people think of selling a 1G service with 1G backhaul (and potentially 10s or 100s of customers buying this service alongside n*100s of customers with 100M service)?
Hi Adam, I think you better have a PPoE concentrator somewhere or you're going to deal with a flood of broadcast, virus and other trash traffic. I also think expecting fewer than 1% of your residential customers to P2P at once is borrowing trouble. I've been out of the ISP game too long to give you hard numbers at today's network speeds, but back when I was in the game, a 100:1 oversubscription ratio for residential DSL was around the boundary of what customers described as poor quality and slow. That number was steadily trending downward, not up, though the official villain then was Bit Torrent instead of Netflix. On the other hand, it might be an interesting experiment to take a utility company approach... Sure we'll give you a 200 amp service with only 1000 amps in the neighborhood, but you don't pay for the 200 amp service you pay for the consumption of kilowatt hours. On the other hand, heat pumps don't get hacked and start drawing the full 200 amp service. Regards, Bill Herrin -- William D.
