This draft is ready to be published as Standards Track RFC but I have some comments.



Major issues:



Minor issues:

-[Page 7], Section 4.1, "If the PCP Client does not know the exact number of ports its requires, it MAY then set the Port Set Size to 0xffff, indicating that it is willing to accept as many ports as the PCP server can offer."

Question/clarification to add: Mention if there a mechanism where the server will know which of the mapped ports are going to be used by the client? and which mappings can be discarded/reused in a subsequent request.



Nits/editorial comments:

-[Page 6], "In particular, the PREFER_FAILURE option MUST NOT be present in a request that contains a PORT_SET option.".

Suggestion: Please add a sentence after this one suggesting why PREFER_FAILURE option MUST NOT be used. It was not clear to me until I read the rest of the draft...although I am still not sure why this behavior is to be a MUST NOT.


-[Page 8], Section 4.3, "There is intentionally no port set capability discovery mechanism.".

What is the intention? I could not find anything on the list discussion. It would be good to clarify this to make this section puroposeful.


-[Page 16] ,  Ref. [RFC7596] should be revised-it still refers to the draft.



Best Regards,



Meral Shirazipour
