摘要

AT&T has expanded the reach of its 40G IP/MPLS backbone network to more than 50,000 miles in the United States. The upgrade includes 18,000 miles of optical ultralong haul routes that the company says will eventually be used to carry voice and data traffic at speeds up to 100Gbps.The company estimates that 40% of IP traffic carried over its backbone will travel through its upgraded 40Gbps platform by year-end, and that it will be able to connect IP/MPLS network hubs in 25 major metropolitan areas within months.
