Cisco, Juniper, Alcatel-Lucent win AT&T IP domain

Carrier, as expected, names three for MPLS/Ethernet/Evolved Packet Core requirements

As expected, AT&T this week named Cisco among its three suppliers for the carrier's IP/MPLS network "domain." The other two are Juniper and Alcatel-Lucent.

We reported in March that this would be the likely scenario. In an effort to whittle down the number of suppliers it works with, AT&T is selecting two vendors - well, three in this case - as its suppliers for certain areas, or "domains," of its service network.

Cisco, Juniper and Alcatel-Lucent will supply routers and switches for the IP/MPLS/Ethernet and Evolved Packet Core domain of the AT&T network. The carrier did not disclose financial terms of the agreements, which are extension of existing agreements AT&T had with all three.

AT&T says it will spend between $18 billion on $19 billion on its network this year. The network carries 18.7 petabytes of IP and data traffic on an average business day, which the carrier says is the equivalent of transporting the entire digitized Library of Congress more than 250 times.  

Traffic volume has doubled over the last four years over the network, which includes more than 880,000 route miles of fiber-optic cable.
