re: PBT Sidelined at BT I know the story says BT isn't throwing out PBT, but it's tempting to see it that way...

What do you folks think? How much trouble is this for the PBT cause?

re: PBT Sidelined at BT Hey, you can tell by my user name that I'm all about Ethernet, but this is just another nail in the PBT coffin, at least for now. I can't imagine any carrier using it until it has an active control plane, which is just getting under way in the IETF (GELS), and point-to-multipoint capabilities.

re: PBT Sidelined at BT Interesting article for sure. Thanks.

The information over here is that BT lowered the standards the second time in the bid so MPLS would succeed after all. New guy in charge get to change new rules I guess.

And the service being rolled out has no traffic engineering enabled. Apples to pomegranites

Morrale: If one doesn't win the first time trough, just play again, with different players, different rules...

Makes all these guys look rather bafoons...

re: PBT Sidelined at BT This smells like death. I have often been surprised at how few smaller carriers and other in the industry were aware of PBT. Its interst always felt narrow considering the press it got(gets). Without a big carrier to legitimize it - I think its in a dire position.

I'm Glad I'm not at a PBT focused startup right now...

re: PBT Sidelined at BT If you want to be an Universal protocol, you have to support a wide range of features to meet at least most users requirements. Or at least partner with other protocols to add more features.

PBT appears to be a stripped down protocol that must not limit the features of co-existing protocols. It does have a useful, very limited application, but it must co-exist efficiently without limiting a wide range of features. So BT will probably wait until they get a network with users established and then determine the usefulness of PBT. I wouldn't bet on it being impimented.

re: PBT Sidelined at BT Without any doubts MPLS is VERY complex technology (if by 'MPLS' you take the whole suit of data and control protocols developed to date and not just bare idea of forwarding with labels). But at the same time it solves REAL needs of carriers.

PBT's claim (at least implied one) always was that MPLS is not just complex, it is overengineered and the same set of problems can be solved easier.

May be. But you can't compare an idea (PBT) with full blown existing implementation (MPLS protocol suite).

PBT has to mature so that comparison MPLS vs PBT becomes comparison of apples to apples. What current announcement does is it puts PBT off fast track into path of 'normal paced' development. No doubt, PBT supporters must have stamina, perseverance and stubbornness if you want to push and pull it along to the point when real comparison can be drawn by potential customers.
And the problem now is that it is not a given fact that PBT as a full suite will be really as simple as PBT bare idea.

I don't think it is death to PBT. I think PBT is a great thing in some situations, metro Ethernet for example. But it is a huge blow. Funny enough this blow just returns things to their logical order they should always had been...

re: PBT Sidelined at BT I wonder if MetroNext is going to change anything for PBT at BT, and when it'll be released.

re: PBT Sidelined at BT Tedium (Pronounced TDM) still rules at NT.

MetroNext
MPE NextTune
20K
TerrorbitInterceptor
8600
OpteraPacketCore
BLUE
Nebraska

All very fine ideas but sadly managed by lesser execs and beancounters. Oh! The Horror ..and the wasted opportunity.

re: PBT Sidelined at BT PBT,

Step up and join your new friends:

Lattiscell/ATM/LANE

CR-LDP

and

RPR.

Please NT tell us what the next hot technology is so we know what not to bother implementing.
