Re: [Rtg-ooam-dt] How to better engage SFC?

Hi Giuseppe,
I was thinking that it would be logical in the gap analysis with conclusion that allocating field for the marking in an overlay header enables use of such flexible measurement method in passive-like OAM manner.

Hi Greg,
Excellent, we'll discuss the problems these drafts are addressing next Tuesday.

Regarding marking method application in SFC, what is you plan for now?
Is a contribution for the gap analysis document good for this goal? or are you thinking of a new draft as is in BIER?

Regards,

Giuseppe

Hi Giuseppe,
thank you for volunteering to help with PM story. It would be great to make it about the marking method in SFC pointing to flexibility of placing the Test Point either at Classifier, SF or SFF. And, as done in PM with the Marking Method in BIER Layer, demonstrate benefit of two-bit long vs. one-bit long field for marking.

As for the listed drafts I have serious concerns that I'll sum and share with the team before our meeting next Tuesday. I'd like to look not into particular solutions described in these drafts but for the problems they are addressing. I think these are real-life problems and we can propose solutions to, solutions based on Common Overlay OAM.

                Regards,
                                Greg

Hi Greg, All
That's for sure! I appreciate your consideration.
The documents you suggested are precious.
In particular, draft-browne-sfc-nsh-timestamp could be considered for the timestamping of NSH packets and be combined to the marking method very well.
The proposed extension to TWAMP to carry services KPI data, proposed in draft-spv-ippm-monitor-implementation-services-kpi, is also suitable for the purpose.
And draft-agv-sfc-performance-measurement-architecture should be the reference for the PM architecture for SFCs

If all of us agree, I could propose some text for the "PM over SFP" Section of the gap analysis document with reference to draft-ietf-ippm-alt-mark and documents quoted above.
I could send you proposed text before next Tuesday call.

Best Regards,

Giuseppe

Hi Giuseppe,

I think it would be interesting to discuss considering proposals that may be addressed using the marking method:

·         draft-browne-sfc-nsh-timestamp

·         draft-spv-ippm-monitor-implementation-services-kpi

Would you have contribution for the gap analysis document too? That would be absolutely great.

                Regards,

                                Greg

Hi Erik,

Yes It is a very good idea.

If all of us agree, we could detail the marking method application in the SFC scenario, by considering some use cases.

Regards,

Giuseppe

Oggetto: [Rtg-ooam-dt] How to better engage SFC?

On the OOAM call this morning a question was raised whether we should present anywhere than RTFWG.

I wonder whether having an OOAM presentation in SFC would help to get more interest and contributions from SFC.

(I don't think we need it for BIER and NOV3 since we seem to have sufficient engagement with those WGs.)

Thoughts?

    Erik
