Nutria would do well to read and understand the facts of life:
In this sense, broadband is like old-fashioned telephone service, where there are always more lines leading from homes to the local switching station than there are going from the station out of the neighborhood. If everyone in a neighborhood picks up the phone at once, some calls won’t go through because there aren’t enough outgoing lines. But that rarely happens, so the system works.
On the broadband network, the over subscription means that one megabit-per-second connection to the Internet is enough to serve 40 DSL accounts, each at a maximum speed of 768 kilobits per second, typical for low-end DSL. So the cost of providing data to each DSL is about 25 cents to 50 cents a month per customer.
Of course, the carrier also needs to pay for the equipment that brings data from the Internet connection point to the subscriber, first through fiber-optic lines and then through DSL or cable.
Over-subscription doesn’t present a problem as long as people are using the Internet for Web surfing, e-mail and the occasional file download. But if everyone in a neighborhood is trying to download the evening news at the same time, it’s not going to work.
“The plain truth is that today’s access and backbone networks simply do not have the capacity to deliver all that customers expect,” according to Tom Tauke, Verizon Communications Inc.’s top lobbyist.
Over-subscription is the essence of packet-switching, boys and girls, and without it we have the good old telephone network. We don’t want that, do we?
