PBB-TE Fades a Little Further

Extreme Networks Inc. (Nasdaq: EXTR) won't support Provider Backbone Bridging – Traffic Engineering (PBB-TE) in the E4G family of mobile backhaul devices being announced today.

Moreover, support for MPLS-TP -- the key packet-transport alternative to PBB-TE -- will be added to the company's entire ExtremeXOS portfolio, says Mark Showalter, director of service provider marketing.

Why this matters
This is a strong sign that PBB-TE won't ever get its mojo back, as Extreme was a very early, and outspoken, backer of PBB-TE.

Last year, vendors and analysts were still saying PBB-TE had enough demand to stand alongside MPLS-TP on feature lists, but the consensus seems to be that MPLS-TP has won the war.

Extreme's decision was "driven a lot by the mobile network providers," Showalter says.

PBB-TE still has some support, though. Ciena Corp. (NYSE: CIEN), Cyan Optics Inc. , Tejas Networks India Ltd. and Tellabs Inc. (Nasdaq: TLAB; Frankfurt: BTLA) are among the other companies still offering the technology.

I listed the vendors to show how *few* are remaining. That wasn't meant to be a statement of PBB-TE power.

The only deployment I can think of offhand is iBurst's.

Thanks! I wasn't aware of iBurst's deployment.

Craig, it's one thing to list the vendors with PBB-TE suppport; but where are the deployments? Are there ANY operational PBB-TE deployments? I'm not aware of a single deployment.

what happened to Shanghai Telecom (see LR 107293, 12 Oct 06, and LR 127709, 26 Jun 07) that supposedly implemented PBT (pre-standard PBB-TE); to Frontier (LR 127033, 19 Jun 07); to Dakota Carrier Network (LR 129259, 17 Jul 07); to Silk telecom (LR 133684, 12 Sep 07); to Mumbai Airport (LR 133685, 12 Sep 07)?

Any update on these (alleged) deployments?

LightReading reported on 9/23/08, "Sprint Joins PBT Club".  Mentions Clearwire and Sprint.

Extreme Networks is an enterprise class vendor.  While the importance of supporting different carrier class resiliency technologies is important, it isn't as important to a vendor that primarily focuses on datacenters, schools, govt, healthcare, etc.

To that point, Extreme touts support for G.8032.  This is a big deal to them in the enterprise world but tablestakes for vendors that deal with operators on a regular basis.  Yes, it is a fine ring resiliency technology and yes it is much better than a proprietary solution (EAPS) - but touting this is akin to touting redundant power supplies.  Whoo-ah.

PBT killed Nortel BT deployment  its could not replace MPLS. 

+NO  MC support and NO ETREE support.

Is any one looking at  http://en.wikipedia.org/wiki/I...

also knows as PLSB

re: PBB-TE Fades a Little Further

There are certainly a few PBB-TE users out there, and that's why I'd expect Ciena -- and probably Extreme, too -- to have to support the technology for years to come.

But there's a cap on that market, in a sense. The big carriers seem to have turned their backs on PBB-TE, and while a few wins like iBurst might pop up... it's looking like PBB-TE's best days are behind it.

Telco Systems pinged us about this -- they'd like you to know they support G.8032 as well, especially in edge and demarc equipment.  Not sure if that counts as the backhaul-specific case Extreme was boasting about, but we'll give them a nod here, anyway.
