Attachments Liaison to IETF on YANG Service OAM models
Dear Jürgen Schönwälder, Tom Nadeau, and Benoit Claise:

The MEF wants to communicate to the IETF NETCONF Data Modeling Language
(netmod) Working Group that MEF has existing YANG Service OAM Fault Monitoring
(MEF 38) and Service OAM Performance Monitoring (MEF 39) specifications.

MEF 38 and MEF 39 are published specifications and can be found on the MEF
public website at:

There appears to be some direct overlap with these specifications and the goals
of the Working Group, specifically in the area of MD, MA (MEG) and MEP
definitions as found in

We request that IETF review and consider using these models, if applicable. We
look forward to feedback from you on this subject.

The MEF Technical Committee meets next in Atlanta in October 27-29, 2014.
