Windomnet
The city of Windom's fiber optic network, called Windomnet, began service in the fourth quarter of 2005. At the time it was built, Windom residents had no access to high-speed internet. The city says it asked Qwest to provide it but were told the company was not interested. After Windomnet was built, Qwest changed its mind. Qwest now provides DSL, competing with Windomnet's fiber service. To this day, Qwest DSL is the only competion for high speed internet. Comcast does not offer service in Windom. Windomnet's business plan called for it to lose money for the first five years, before finally breaking even. In 2008, the city tells us, Windomnet lost $108,000. The proposed North Saint Paul fiber optic network is called Polarnet. The Polarnet business plan calls for it to break even within three years. That, despite high speed internet competition from Qwest DSL and Comcast broadband. Windomnet was financed through revenue bonds. That means if Windomnet continues to lose money, the investors lose. Polarnet would be financed through general obligation bonds. That means if Polarnet does not make enough money to make the loan payments, the city still has to find a way to pay. And that could mean property taxes go up. Polarnet's business plan says it will break even if 27 percent of the city's residents sign up. Windomnet, after three years, provides phone service to 52% of the households, high speed internet to 45% of the households and cable TV to 76% of households. A Windom trucking company uses the fiber optic service to keep track of and communicate with rigs all over the country. The company told us they would have left town had the city not provided the service. Businesses in North Saint Paul already have access to Qwest DSL and Comcast broadband. Part of the city's pitch is that Polarnet will attract new business to North Saint Paul. We asked if they'd ever heard from businesses that decided against moving to North Saint Paul because of the lack of a fiber network. The City Manager told us a couple of "server farms," large computer storage facilities, decided against building there because the available bandwidth was not sufficient. |

"The Grid"
obsolete - thanks to a high-speed internet developed in Geneva. It's called"the grid", it's more than 10,000 times faster than broadband. Massiveinformation that takes the broadband hours to download can be done in a matterof a few seconds with "the grid".
First, a disclaimer: I know very little about "the grid," but a bit of research suggestedto me that it is related to distributed computing, which involves linking togethera great deal of computing power and applying it all to the same problemsimultaneously. Distributed computing has been around awhile.
"The Grid" is like that. But for The Grid to work, the computers must be linked by something,and most often, that something is the fiber optic cable that will be the backbone of the CookCounty broadband system. Fiber optic is estimated to have a life span, if I remember correctly,of 40 to 50 years. While the equipment that uses fiber optic may evolve and change, fiber opticitself is not expected to go obsolete any time soon.
Don't just take my word for all of this. At the CERN site itself, I found an interesting articleentitled: "The Grid: Separating Fact from Fiction." Below, I have printed a few excerpts, butyou can read the entire article yourself at http://public.web.cern.ch/public/en/Spotlight/SpotlightGridFactsAndFiction-en.html
Fiction: The Grid will replace the Internet.Fact: Grid computing, like the World Wide Web, is an application of the Internet. When the LHC turns on, data will be transferred from CERN to 11 large computing centres around the world at rates of up to 10 gigabits per second. Those large centres will then send and receive data from 200 smaller centres worldwide. All this data transfer will take place over the Internet. Dedicated fibre-optic links are used between CERN and the large centres; the smaller centres connect together through research networks and sometimes the standard public Internet.
Fiction: People will be able to download movies 10,000 times faster using the Grid.
Fact: First, in order to get such data-transfer rates, individuals would have to do what the large particle physics computing centres have done, and set up (or lease) a dedicated fibre-optic link between their home and the source of their data. Second, today’s grid computing technologies and projects are geared toward research and businesses with highly specific needs, such as vast amounts of data to process and analyse within large, worldwide collaborations. While other computer users may benefit from grid computing through better weather prediction or more effective medications, they may not be logging onto a computing grid anytime soon. (Something called “cloud computing”, where your programs are run in a central location rather than on your own computer, may also be on the horizon.)
Fiction: The Grid was invented at CERN.
Fact: The first pioneering steps in grid computing were taken in the US. The term “grid computing” was first used in a book by Grid pioneers Ian Foster and Carl Kesselman, as a metaphor for making computing power accessible in the same way as electrical power. The LHC Computing Grid Project, led by CERN, uses resources contributed by grid projects around the globe.
