Dear all,

Coming back to this issue discussed today in the WG meeting.



Thanks Alex for refreshing my mind during the session (I lost context 
here, sorry).

You (rightly) said: We don't expect the IPFIX observation ID value to be 
the same as the UDP notification Observation-Domain-ID value because the 
UDP notification observation-domain ID is basically the Publisher ID (as 
opposed to a line card Id in IPFIX).

However, we have to recognize that the observation domain concepts and 
definitions are similar between UDP-NOTIF and IPFIX.
- Observable Domain & Observation Domain ID in 
draft-ietf-netconf-distributed-notif
- Observation-Domain-ID in draft-ietf-netconf-udp-notif-09
Btw, note the hyphen difference.

I believe that one of two drafts (I guess 
draft-ietf-netconf-distributed-notif, but not sure) should contain an 
"operational considerations" section expressing the difference between 
IPFIX and UDP notification observation ID ... basically Alex's answer to 
my question. I believe this would also address Rob Wilton's point.

Regards, Benoit
