AT&T today said it has expanded to 40 Gb/s capacity on more than 50,000 miles
of its IP/MPLS national network, as part of the latest push to meet growing
demand for online video and other IPbased traffic.
The announcement comes a few weeks after Verizon announced turned up 40 Gb/s
links but only along some East Coast routes. One other major difference –
Verizon is working with Juniper Networks, while AT&T’s upgrade is based on Cisco
Systems CRS1 technology, the two companies said today.
Both service providers are already tipping their hands at the next step – 100 Gb/s
transport. AT&T said its nextgeneration network includes 18,000 miles of
optical ultralong haul routes that will eventually be able to carry traffic at
100 Gb/s, adding that more than 40% of its IP traffic will ride over its nextgen
network by the end of 2007. Verizon has said it will start using 100 Gb/s in
either 2008 or 2009.
“As the demand for Internet and IPbased 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,” said John
Stankey, group president of Telecom Operations at AT&T, in a prepared statement.
“Our industryleading deployment of 40Gigabit technology enables us to stay
ahead of our customers’ growing need for bandwidth and to continually deliver
the fast, reliable connectivity our customers need to connect with their world.”
