The IEEE announced that it is near to a formal standard on connection-oriented Provider Backbone Bridging - Traffic Engineering (PBB-TE), the technology closely related to provider backbone transport. PBT was hyped as a connection-oriented solution in recent years, but last year began to take a back seat to MPLS-Transport Profile (also called Transport-MPLS) as carrier support--and in turn vendor support--for PBT appeared to wane.
The PBB-TE standard is expected to be ratified within weeks, with a review coming up in June, Light Reading reports. Meanwhile, the MPLS-TP standard currently in the works at the ITU is reportedly not near completion, which could allow PBB-TE to make an impact among companies looking for a standardized carrier Ethernet transport solution to replace Sonet/SDH. It remains unclear how extensively PBB-Te could be deployed, though LR reports that it could see life in backhaul and for data center connectivity.
