PBB-TE = Standard

NOON -- Word on the Ethernet transport standards street is that Provider Backbone Bridging - Traffic Engineering (PBB-TE), the controversial connection-oriented Ethernet technology formerly known as PBT, is now a ratified Institute of Electrical and Electronics Engineers Inc. (IEEE) standard.

The timing is about right: Back on April 21 we said PBB-TE, or P802.1Qay in pure IEEE-speak, was weeks away from becoming standardized. (See IEEE to Rubber-Stamp PBB-TE .)

It seems the official announcement will not be long in coming, so keep an eye out for it.

In the meantime, here's a statement from Hayim Porat, CTO at Ethos Networks Ltd. , who is an IEEE standards committee member and co-author of the PBB-TE standard:

    We believe that as a result of the completion of the standardization process the industry will see an increase in service providers’ interest in deploying carrier Ethernet solutions based on PBB/PBB-TE. Service providers that were forced to settle on non-standard vendor-specific implementations and those who were reluctant to invest in pre-standard solutions, now have an IEEE-approved reference they can turn to.
Over to you, MPLS camp...

MPLS-TP Standardization has already begun:

re: PBB-TE = Standard

The article above points out that PBB-TE standardization process is complete.  As ISP-Guy observes, MPLS-TP standardization ‘has begun’.  Given the task at hand, and the issues yet to be resolved, then the real question is: when will the MPLS-TP standardization process complete?


Given where MPLS-TP currently finds itself in this standardization process, I have not seen any vendors sticking their neck out categorically stating when this will occur.

re: PBB-TE = Standard Well, I'm sure you'd find ALcatel-Lucent as well as those folk on the working group for the standard saying mid-2010, unless things have changed.

Maybe there's an update though?

re: PBB-TE = Standard

I wonder if Alcatel-Lucent is sticking to this estimate. RFC 5586 only deals with the Generic Associated Channel which, while dealing with a critical requirement, is only a small portion of the overall solution. Until some key RFCs are published, any estimated completion date for a standard should be viewed with some skepticism. 

For example, a new version of the MPLS-TP requirements was published on Monday of this week, and until this document is complete, the remainder of the work is in limbo.

In my opinion, mid-2010 is overly optimistic, at best.
