re: Poll: Opex Gives PBT an Edge To naysay PBT at this early stage is to expose a bias. No one likes their investment (time or money) exposed to something potentially better.

I remember MS-DOS getting trashed by the Johnny Apple-seeders. In that case, their OS was better, they just got out-marketed. Care to debate if MS-DOS was a success?

Is PBT better than MPLS? - let's find out and see, shouldn't we?

re: Poll: Opex Gives PBT an Edge Blah Blah Blah, havent we heard this before. Dumb things are cheaper, but the are capable of doing less. PBT, minimum wage networking. Minimum wage, whats that in the good old US of A $6 an hour?

re: Poll: Opex Gives PBT an Edge LR has outdone themselves this time on making up a worthless poll and then touting the results ... how can ANYONE have an informed opinion on BPT opex vs. MPLS opex, given that there are exactly ZERO PBT deployments in the field? Meanwhile, MPLS-based VPNs are bringing in about $US6B in service provider revenues this year according to Infonetics ...

re: Poll: Opex Gives PBT an Edge litereading: "To naysay PBT at this early stage is to expose a bias."

Take the first question - would you immediately deploy your ethernet services using MPLS or PBT - there were >50% (and falling fast) respondents saying they would. And the overwhelming reason was OPEX.

To claim that PBT saves OPEX when it hasn't really proven itself is exposing a bias.

"Is PBT better than MPLS? - let's find out and see, shouldn't we?"

Sure, we'll give norty a chance to shoot themselves in the eye (both feet are already gone).

Perhaps if the question had been worded as: "Are you biased towards MPLS or PBT," then this poll would have been more accurate.

re: Poll: Opex Gives PBT an Edge some free marketing for NT:

"NEW and improved ethernet, from the people that brought you virtual routing and CR-LDP!"

re: Poll: Opex Gives PBT an Edge
Has anyone actually asked Nortel to PROVE their OPEX savings - I mean PROVE it, with a real customer - not just opinion but hard proof. I hope they are right otherwise this could be another dot-com like hype. Many people might hope it is true but you have to ground yourself in reality - show us the facts NT and also include the possible revenue from PBT given its lack of functional capability.

My bet is that they may be able to show some lowering of opex combined with a lowering of revenue. I would like to think that this debate does at least make MPLS vendors look at their approach to opex - if they could show some reductions while maintaining the revenue seen today that would be a great result for the industry. Sorry NT but you might have the right idea with the wrong technology.

re: Poll: Opex Gives PBT an Edge Hello Metroman,

You're asking the right question, why would OPEX for PBT be lower than MPLS? Let's assume for the moment that PBT is not about to adopt MPLS as its control plane and retains a pure manager provisioned approach. Also you deploy MPLS in a manager provisioned approach and all you do are VLLs.

I would assume then that the biggest OPEX influence is the management system itself. So does PBT/Ethernet offer better MIBs than MPLS? Are there more or better management applications for PBT than for MPLS? What is it that makes VLL management in MPLS that much more complicated than using PBT? And why would any difference have a more than marginal impact on overall OPEX?

Anyway, its all speculation and the whole PBT discussion seems to be jumping from one value prop to the next. It was said be simple, but why then is everyone confused? Even the B in PBT is misleading. It's all about if and when. But if my grandfather would be wearing a skirt, that wouldn't make him my grandmother.

Manageability and OPEX are key concerns for service providers to scale the business, but when it comes to purchasing network management software there's always surprisingly little money they're willing to pay for it. It's really seen as a cost, not an asset.

Well, it sometimes makes you appreciate what you have when you can see what the alternative might be. In the U.K. we used to have two polarized political parties with completely different ideologies. Now we have a choice between a wet blanket and a damp cloth...

re: Poll: Opex Gives PBT an Edge Hi Yarn:

Not sure what the source of confusion would be w.r.t. what PBT is. In essence lurking inside every bridge is a honkin huge cross connect, (look at the .1d static subtree in the MIBs) which when combined with Y.1731 and 802.1ah has some useful properties almost all of which are well specified.

Being one of those Nortel "idlers" who voted despite the question (BTW most of the 30000 of us must have been busy), I went for operational savings. Having spent several years in MPLS OAM, I felt qualified to cast my vote that way ;-)
