Just a few minor comments. Minor level comments: (1) p 5, sec 3.4. Active OAM Using GRE-in-UDP Encapsulation [RFC8086] has defined the method of encapsulating GRE (Generic Routing Encapsulation) headers in UDP. GRE-in-UDP encapsulation can be used for IP DetNet OAM as it eases the task of mapping an OAM test session to a particular IP DetNet flow that is identified by N-tuple. Matching a GRE-in-UDP tunnel to the monitored IP DetNet flow enables the use of Y.1731/G.8013 [ITU-T.1731] as a comprehensive toolset of OAM. The Protocol Type field in GRE header must be set to 0x8902 assigned by IANA to IEEE 802.1ag Connectivity Fault Management (CFM) Protocol / ITU-T Recommendation Y.1731. Y.1731/G.8013 supports necessary for IP DetNet OAM functions, i.e., continuity check, one- way packet loss and packet delay measurement. A few minor comments on this paragraph: 1. The section title is about "Active OAM Using GRE-in-UDP Encapsulation" but the text seems to be more specifically referring to Y.1731. Should the title of the section be refined? 2. Perhaps "set to 0x8902 assigned" => "set to 0x8902, assigned" 3. The last sentence of the paragraph doesn't scan properly. (2) p 6, sec 7. Acknowledgment TBA Just a note that this is still blank, and you may want to remove this section if you don't wish to acknowledge anyone. Regards, Rob
