Crunch Time for PBT

1:30 PM -- Provider Backbone Transport (PBT) is the carrier Ethernet technology du jour -- well, it is on Light Reading at least. (See PBT in the Spotlight.)

But it's been two years since BT Group plc (NYSE: BT; London: BTA) and Nortel Networks Ltd. started banging the PBT drum, and, so far, the British carrier is still the only major operator to have committed to deploying it, though there's plenty of support from the vendor community. (See BT Likes Nortel's New Ethernet Flavor, PBT/PBB-TE Guide: Vendor Talk, and A Guide to PBT/PBB-TE.)

So what about other carriers? BT is presenting at the upcoming Ethernet Expo: Europe 2008, and will provide an update on its Ethernet product plans. (See BT to Update on Ethernet Plans .)

But plenty of other carriers will be there, too, from around Europe, Asia/Pacific, and North America. We'll be sounding them out about PBT in an effort to figure out whether BT is just a really early adopter, with others to follow its lead, or whether the U.K. incumbent will end up being PBT's only major carrier flag-waver.

And we're interested in what you think as well. Take our new PBT poll here.
