BROOMFIELD, Colo., Jan. 7, 2013 /PRNewswire/ -- Level 3 Communications, Inc.
(NYSE: LVLT) and XO Communications today announced they have entered into a
long-term settlement-free Internet traffic exchange agreement, also commonly
referred to as a peering agreement, that is based on the bit-mile balance

The peering agreement ensures that customers on each of the two Internet
service providers' networks can continue to exchange data with customers on
the other service provider's network efficiently and cost-effectively. It is
based on the bit-mile peering approach which measures both the volume of
traffic exchanged and the distance over which that traffic is carried by each
network. In order to keep the relationship equitable and settlement-free, both
networks carry approximately the same bit-miles of data, a model that promotes
efficient, high-quality service for customers, while ensuring a balanced cost
burden across each network.

As the Internet continues to grow and evolve, this approach resolves the
imbalances that can occur in traffic patterns and that would otherwise result
in increased network costs to one provider or the other involved in a peering
relationship. When asymmetry occurs, the Internet traffic carriers agree to
adjust traffic routing and interconnections to maintain a fair and equitable
relationship between the two networks. They must also maintain the ability to
exchange traffic in a scalable, resilient and reliable manner so that
consumers can enjoy the best possible Internet experience. The bit-mile
arrangement ensures this consumer benefit while doing so in a way that is
equitable to both Level 3 and XO.

"Level 3's primary focus is on providing quality service for Internet
consumers," said Jack Waters, Level 3's chief technology officer. "We look
forward to working with our peering partners to drive broader adoption of this
bit-mile model to ensure fair and equitable interconnection. We are also
working with providers of traffic-flow monitoring systems to make the
measurement process straightforward and consistent across the industry."

"XO Communications supports equitable settlement-free peering to ensure fair
and unconstrained interconnection," said Randy Nicklas, senior vice president
and chief technology officer, at XO Communications. "This agreement will
ensure a balanced backbone cost burden between our two networks as we continue
to grow while providing high-quality service for our respective customers."

The peering agreement also contains provisions to add capacity and establish
new interconnection locations between the two networks to stay ahead of
growing traffic demand. This approach offers flexibility to each network while
improving performance and reliability for customers.
