Is Ciena cooking a PBT control plane?
Recently I reported that Soapstone Networks, which pioneered the market for Provider Backbone Transport control planes, won’t be alone for long. Equipment vendors in the PBT space know that other control planes have been developed for the Ethernet transport technology and expect them to be unveiled soon. My source said a pair of startup suppliers will probably emerge in the first half of this year. As I said, one of them seems likely to be Gridpoint Systems. I wonder if another near-future entrant will be Ciena.
