The IEEE ratified an industry standard for PBB-TE (Provider Backbone Bridges - Traffic Engineering) technology yesterday at a meeting of the engineers’ organization in Tokyo.
The approval of 802.1Qay is good news for vendors like Fujitsu Network Communications and Ciena (NasdaqGS: CIEN), whose optical networking platforms include support for the connection-oriented carrier Ethernet transport technology, and for Nortel Networks (NYSE: NT), which first championed it back in 2006, when it was called PBT.
PBB-TE’s standardization also potentially gives it a leg up against its rival, MPLS-TP, which is based on Layer 3 routing technology rather than carrier Ethernet. Backed by big names such as Alcatel-Lucent and Cisco Systems, MPLS-TP was proposed only last year as compatibility concerns grew over T-MPLS, a transport technology being standardized by the ITU-T. So with MPLS-TP not yet standardized, PBB-TE supporters can at least brag about their status for a while.
In a sad twist of irony, perhaps, the IEEE ratified PBB-TE just one day after Soapstone Networks, a long-struggling software startup focused primarily on PBB-TE, announced that its board had okayed a liquidation of the company and that it had dismissed 50 remaining employees.
