LR Live: Verizon Plots 100 GigE RFP
Dr. Stuart Elby, vice president of network architecture and enterprise technology, talked of the carrier's need for faster packet-optical transport technology, both in its backbone network and at the metro level, during his keynote at Light Reading's Packet-Optical Transport Evolution event at the Westin Hotel in Times Square, New York City, on Tuesday.
"We're trying, in the backbone space, as quickly as possible, to get to 100 GigE," Elby told the crowd.
That means Verizon expects to wrap its backbone device specifications "late this year" with an RFP "in 2010," Elby said. Metro networks "started upgrading two or three years" to 40-Gbit/s Ethernet, Elby said. "We're very far along in metro, quickly trying to catch up in the backbone. It's going to take a few years, though."
The mention of 100 Gbit/s complements Elby's statements, in March, of wanting packet-optical transport systems (P-OTS) in the long-haul network. (See Verizon Rethinks Long Haul.)
And Verizon's interest in 40- and 100-Gbit/s Ethernet links should come as no surprise. The rise of wired FiOS and wireless Long Term Evolution broadband access networks mean more bandwidth is pouring in from the edge. Elby said this means the carrier will need "terabit switching" capabilities at the metro level and "tens of terabits" in the backbone.
Part of this is simply because there is more data traffic on networks of all kinds. Part of it is because of "the increasing amount of traffic that is time sensitive," including VoIP and video, he added.
This doesn't mean, however, that Verizon will abandon Sonet any time soon. "Sonet will live on a while longer yet," Elby said, envisaging the legacy technology as just another layer in the network topology. "We're not building out a greenfield [network] here." — Dan Jones, Site Editor, Unstrung
