    ya thanks for the link , but i am not asking how the communication is done between tier 1,2,3 but i am asking how bandwidth is produced , just like electricity is produced from water similar how bandwidth is produced . is the there limit or produced just on demand . once up on a time internet users running on dsl modems but broadbands ,3g etc came to existance so how the band width speed increased . thanks for the reply

    as dvk01 stated, you are asking how to partake in neurosurgery whilst holding a bic pen. You need to really start at the bare bones level (also that link that dvk01 provided), and start taking notes.

    thanks,

    For the US there are sites called Metropolitan Area Exchanges. There is a East coast one and a West coast one. These are major network sites which pretty much form the backbone of the Internet in the US. These sites are also wired to other sites in other countries performing the same function.

    How it works there is the major Telecom companies have already paid out of their own pockets the infrastructure there. They then sell circuits provisioned for a certain speed/bandwidth to the next tier which then sells their provisioned circuits to the next tier.

    I don't understand the need to know this information. Plus it's not a simple answer nor will any of the backbone providers will willingly give out this information. But just as a reference, one of the carrier class routers used in Telecom applications is a Juniper T4000. This router has a max bandwidth of 3.84 Tbps. Now imagine a large data center with racks of such equipment and you can get a general picture.
