Re: [Teas] Advancing some documents

Yeah, thanks Dan.

One objective of this document is to try to anchor (architecturally) the many and varied approaches in different projects and IETF I-D all of which focus on some form of controller/orchestrator in which PCE plays a central role and where PCEP is proposed as a "southbound interface."

I think it is important that "we" take hold of this problem space and lead so that we are able to rationalise which mechanisms make sense and which do not, and so that we can keep technical oversight of PCE and PCEP.

So why is this I-D in TEAS? Well, when the previous use case and requirements drafts were doing the rounds, they were sent from PCE to TEAS because the space was considered to be wider and more general than simply a use of PCE. It seemed natural, therefore, to place this draft in TEAS where architecture work is done.

Hi All,

Just like to echo Cyril’s comments that the PCE-based control architecture is a really interesting topic and the authors have done great job of documenting recent discussions on and off the PCE list. 

The current open source SDN controller platforms already implement some basic PCE architecture and PCEP extensions, but there is growing trend for more capability (TE automation, optimisation and resiliency) to be enabled using PCEP. Having this document that summarises architecture, applicability and capability - and possible gaps - is very useful. I would also like to see the document progress in the TEAS WG. 

BR, Dan.

Hi, 

I am supporting the draft-zhao-teas-pce-control-function dcocument and look forward to see it progress in the WG.
This is a good summary of the current architectures and discussions.
Best Regards, 
Cyril

A poll on this will be out shortly.

It would be good to get a little more on this one from the WG -- either
on list or in session. We individually are supportive of the work and
look forward to seeing in pursued in the WG.

The merges look good - but there's only been a few comments on the list
since it was updated.  So this falls into the same boat as the prior
draft. - We'd like to hear more from the WG before polling.

Thanks,
Lou and Pavan
