Ciena Falls in PBT Camp

3:50 PM -- In the panel on Packet Optical Transport at Light Reading's Optical Expo today, Ciena Corp. (NYSE: CIEN) product marketing manager Andy McCormick admitted that his company may have picked a side in the battle between provider backbone transport (PBT) and Multiprotocol Label Switching (MPLS).

Ciena is a BT Group plc (NYSE: BT; London: BTA) supplier, and that carrier has been pushing its vendors to adopt PBT as their technology of choice, but Ciena had until recently said it was agnostic on the choice of technology. (See Ciena Continues Ethernet Push and BT Pressures Vendors Over PBT.)

So it might have surprised some when McCormick has the following to say about Ciena and PBB-TE (Provider Backbone Bridging Traffic Engineering, the IEEE's name for the technology):

"We find ourselves falling in the PBB-TE camp, not because of any sort of religious belief, but because we believe PBB-TE is the favored technology that's going to be deployed more widely."

Now that Ciena is fully in the PBT camp, who's next?

re: Ciena Falls in PBT Camp Ryan:

Thanks for attending the session and your interest in how Ciena is supporting connection-oriented Ethernet with our Performance Grade Ethernet approach. I just want to make a couple of clarifications to your post. First, in your first paragraph, the battle is between PBB-TE and T-MPLS, not PBT and MPLS, just wanted to point that out since it's a subtle but important distinction.

Second, I would say it's a slight mischaracterization to say we've "picked a side", I think it's more accurate to say the market is showing a preference for PBB-TE and we plan to deliver solutions that meet that demand. As I say in the quote, we remain agnostic about the technology since they both address the same problem. Our goal is to create deterministic performance in large scale Ethernet networks and make it easy to manage.
