AT&T has announced the selection of Alcatel-Lucent, Cisco, and Juniper Networks as its Domain Suppliers for IP/MPLS/Ethernet/Evolved Packet Core equipment needed for its IP-based network. The multi-year selection covers equipment used to route and forward IP packet traffic (voice, video, and data) through AT&T’s network.

AT&T’s Domain Supplier program, launched in September 2009, facilitates a more collaborative relationship with its equipment and software suppliers, enabling AT&T to have the best technologies in place to serve its customers.

The AT&T network carries 18.7 petabytes of IP and data traffic on an average business day, the equivalent of transporting the entire digitized Library of Congress more than 250 times.  This traffic volume has doubled over the last four years.  The network includes more than 880,000 route miles of fiber-optic cable.
