Hi Nagendra,
thank you for your comments.
I agree with PMTUD. Though am not certain about the ECMP as far as pro-active monitoring if only tracing, i.e. on-demand. I think it would be great topic for us to discuss during the next call.
Would January 5th, 2016 @ 07:00 PST work? Would Tuesdays @ 07:00 PST work as regular meeting time?

                Regards,
                                Greg

Hi Greg,

Merry Christmas and Happy New year!!

It is a good start. A couple of points that quickly popped up are below:

1. ECMP awareness - I think we should also include ECMP awareness as one of the requirement.  We may need a right terminology that depicts ECMP and is applicable on different overlay.
2. Path MTU - I see this as one of the topic coming up with different overlay. It is better to include this in the requirement.

Will read more and share any more comments.

Thanks,
Nagendra

Subject: [Rtg-ooam-dt] O-OAM Requirements

Dear All,
happy holidays, Merry Christmas and Happy New Year to All!

I put down some OAM requirements. Greatly appreciate your comments. Can we put it somewhere, somehow for everyone to edit?

You'll notice that some requirements are explicitly point to unidirectional character of OAM. I think that services provided y an overlay network are unidirectional and bi-directional Fault Monitoring and Performance Measurement are unnecessary. Though in some cases egress node may use IP network to send notification to the ingress node. What do you think?

                Regards,
                                Greg
