|  New Backbone bandwidth to be added
Check the following article:
»www.pcpro.co.uk/news/210999/inte···oom.html
Interestingly enough, it also says: "Yet, most of the bandwidth bottlenecks are found in the "last mile" of connections to the home, and not the undersea cables that underpin the worldwide internet infrastructure. Indeed, many experts believe that there is abundant amounts of "dark fibre" that remains unused in oceans across the world."
BINGO!
Can't wait until Bell changes the sping and start saying that there is no backbone capacity and they need to throttle to "save"  the Internet. |

| There is a difference between bell backbone and the whole internet backbone.
Bell has a backbone to some exchange in new york.
I am in the ottawa region so it means the bell backbone part I use is:
Ottawa ---> Montreal ---> New York.
From New York its another provider (Telia for example).
The part of network bell own (Montreal --> New York) has nothing to do with the undersea cables. I doubt bell backbone is saturated but the top level ones might be.
They also have to predict what kind of bandwidth will be used in 10 years. If you upgrade the last mile connections to 20mbps down and up, the internet backbone has to be fast enough to sustain it.
Top Level Backbone
(Let say Telia or level3)

I think its a good idea to upgrade the top level before the last mile 
In this case, bell can still say its backbone is overused because it doesn't have anything to do with the top level backbone (or internet backbone) being upgraded. |
