re: BT Reconsiders PBT Plans "Why we still need PBT? we need PBT is because some vendor want to show off the technology. the senior management team want to show themself, how clever they are! "

douaibei, that is just inflammatory garbage.

PBB/PBB-TE was created because there are serious challenges scaling MPLS (originally an Enterprise technology) to the carrier environment, otherwise why was there an effort to create a T-MPLS standard that recent got sunk?

Yes, PBB/PBB-TE isn't as long in the tooth as MPLS, but there is a fundamental benefit to simply carrying IP over Ethernet instead of IP-over-Ethernet-over-IP-over-Ethernet (PWE over MPLS). Many carriers are asking for it after their MPLS networks ran into scaling challenges.

re: BT Reconsiders PBT Plans BT has been a hugh research organization seeking the latest technology and aggressive plan did attract the spotlight from the world.

However the PBT still not mature and the standards pending to closure. Compare MPLS there is much work to do regarding the provisioning and management. and The PBT system can be very complicated if it want to achieve the claimed benefits: operation, provisioning. MPLS has been "quite mature" and there is evolving path to support more service and simplify the architecture.

Why we still need PBT? we need PBT is because some vendor want to show off the technology. the senior management team want to show themself, how clever they are!

We do need a technology to simplify the operation and prepare the coming challenge, but should we optimize the old MPLs technology and try to find a way out? or should we develop something else?

We will not have clear answer, but "Old technology" can probobaly fix the challenge of the future and its cost less.

We live in a world of making money with proper technology not best technology.

re: BT Reconsiders PBT Plans Well, there is always a limit to what even the Marketing campaign can do for you. Nortel was very good on promoting PBT. Looking closer into the technical details it has been evident for quite some time that it does not offer any significant advantage over MPLS. At the end of the day PBT will have to prove in the field. Reality check.

re: BT Reconsiders PBT Plans "...but "Old technology" can probobaly (sp) fix the challenge of the future and its cost less."

Good point - like, why did we need IP when we had good o'l TDM. You would think this whole industry of telecom is all about technology. And we need to protect those MPLS vendor's margins, don't we?

Got to go, my neighbor needs to use the party line. Bye.
