[James Guichard <[e-mail]>]

Hi Med,

Thank you for doing this!

I think the following questions are relevant and should be clarified as part of the draft text:

(1) Should the O-bit be set ONLY for OAM packets that are specific to the SFC service layer?
(2) Should the O-bit be set in the cases where a solution uses the next protocol field in the NSH header? In this case what is the purpose of the O-bit given that the next protocol field already indicates the expected behavior?
(3) If the O-bit is set is it the expected behavior to find relevant SFC service layer OAM information ONLY in the context headers?
(4) If the answer to (3) is no then what is the sequence of behavior to find the OAM information? (1) look in context headers and then next protocol?, (2) look at next protocol and if not an OAM protocol look in context headers?, (3) some other sequence?

Jim
