KEY POINTS:
NEW YORK - AT&T has switched on its high-speed backbone network, which is designed to ferry data traffic across the US four times faster.
AT&T has begun placing traffic on its so-called "ultra-long haul" network, which boasts a capacity of 40 gigabits per second, meaning consumers will be able to download large files quicker and more easily stream online videos to their computers.
Carriers have been upgrading the backbone network - the underlying pipes needed to move data across extremely long distances - to meet the increasing demand in bandwidth-intensive programs and videos.
"As the demand for internet and IP-based applications continues to explode, IP traffic on the AT&T network has doubled throughout the past two years, and we fully expect this substantial growth to continue in the future," John Stankey, president of telecom operations at AT&T, said in a statement.
The company, which is deploying routing equipment supplied by Cisco Systems Inc., has upgraded 80,463 kilometres of its network and plans to connect 25 major metropolitan areas in the next several months.
AT&T does not break out the cost of the network upgrade, but a spokesman said the expenses were covered under the company's overall capital-expenditure outlay.
In addition to a faster connection for consumers, the upgrades will help ease the capacity requirements for the company's U-Verse internet-based TV system.
While the network is the first in the U.S., Verizon Communications Inc. said that this month it would begin building a 3,218-kilometre backbone network connecting major cities in Europe.
Both companies plan to push the 40-gigabit standard in the US and eventually upgrade to 100 Gbps.
