[Rtg-yang-coord] UPDATE [Re: Yang model for LDP/mLDP]

["Kamran Raza (skraza)" <[e-mail]>]

Hello MPLS/Rtg-Yang-Coord team,

With reference to our earlier email (in Nov 2014), this email is to provide you an update on this activity:

1 - The design team has evolved in last few months and currently comprise following members:

     Kamran Raza: Cisco
     Reshad Rahman: Cisco
     Xufeng Liu: Ericsson
    Santosh Esale: Juniper
    Xia Chen: Huawei
    Himanshu Shah: Ciena
    Stephane Litkowski: Orange
    Rajiv Asati: Cisco
    Nagendra Kumar: Cisco
    Vishnu P. Beeram: Juniper
    Manan V: Comcast
    Eddie Chami: Cisco
    Jeff Tantsura: Ericsson

2- We have had more than dozen weekly meetings over the course of last 4 months to disucss and define the data model.

3- We have completed ph1 and ph2 of our planned work items before IETF 92:
       ph1- Overall config model/hierarchy (keeping LDP/mLDP/MT in mind)
       ph2- LDP: cfg, notifs, rpcs

4- We have just posted our I.D rev –00 and plan to present this in upcoming IETF 92.
http://www.ietf.org/internet-drafts/draft-raza-mpls-ldp-mldp-yang-00.txt

5- Next goal:
     a- Present draft –00 in IETF 92 and get some early feedback
     b- Complete ph3 and ph4 and post next revision before IETF 93.
         ph3- mLDP: cfg, notifs, rpcs
         ph4- LDP: state

Thanks.

Subject: Yang model for LDP/mLDP

Hi,

We would like to bring into your kind notice that a multi-vendor team has started working on the design of the Yang model for LDP/mLDP.  Currently, the team comprise following members:

  Robin Li - [e-mail]<mailto:[e-mail]> (Huawei)
  Jescia Chen - [e-mail]<mailto:[e-mail]> (Huawei)
  Kamran Raza  - [e-mail]<mailto:[e-mail]> (Cisco)
  Reshad Rahman - [e-mail]<mailto:[e-mail]> (Cisco)
  Santosh Esale - [e-mail]<mailto:[e-mail]> (Juniper)
  Vishnu Pavan Beeram - [e-mail]<mailto:[e-mail]> (Juniper)
  Himanshu Shah - [e-mail]<mailto:[e-mail]> (Ciena)

The team had our first formal meeting today and we have scheduled calls to meet weekly to make progress on LDP yang model in upcoming weeks. We will keep MPLS WG and rtg-yang-coord alias posted with regards to our progress, as well as, solicit input as/when required.
[ P.S.:  If you wish to contribute to the design of LDP/mLDP yang model, please let me know accordingly by sending an email and I will add you to the team / meeting invite]

FYI, following is the summary of the main points discussed/agreed in our first meeting:

1- The scope of our work (and document) includes:
- LDP, mLDP, and Multi-topology (LDP/mLDP)
        - Config, Operational State, Notifications, and RPCs

2- We have broken the effort into following phases:
       ph1- Overall config model/hierarchy (keeping LDP/mLDP/MT in mind)
       ph2- LDP: cfg, notifs, rpcs
       ph3- mLDP: cfg, notifs, rpcs
       ph4- LDP: state
       ph5- mLDP: state
       ph6- Multi-topology (everything)

3- The plan is to have the ph1-3 completed before next IETF and the draft posted with the update.

4- In the meantime (and in parallel), we will continue to attend MPLS level Yang meetings (to be arranged by Tarek)
    to define MPLS common base, and leverage LDP yang accordingly.

5- The next meeting/call for LDP Yang will be on Tue Dec 2nd with the following agenda:
     - Complete discussions on ph1.
     - Deep dive into ph2 (define overall LDP cfg tree, followed by expansion of each container)

Rgds,
