Verizon enters second phase of IPv6 transition

COLORADO SPRINGS, Colo. Verizon Business is moving to a second phase of its global rollout of Internet Protocol Version 6, using an existing Multiprotocol Label Switching network as the platform for "dual-stack" IPv4/v6.

The engineering effort is being led by Daniel Obi Awduche, who pioneered Generalized MPLS at Movaz Networks and helped lead the IPv6 backbone update at MCI Communications, which was later acquired by Verizon.

The genesis of the network was formed from MCI's Very-High-Performance Backbone Network Service, which became IPv6-capable in 1998 in its vBNS+ instantiation. Because this network was the second to be allocated IPv6 address space by the American Registry for Internet Numbers, the federal government began working closely first with MCI, then with Verizon Business, to use vBNS+ to meet the U.S. government mandate to turn to IPv6 by mid-2008.
