Thank you for your comments, they have been resolved together with other last call comments. We are now ready to proceed and request publication. A diff by the reviewed version and the new will be found at: http://tools.ietf.org/rfcdiff?url2=draft-ietf-ccamp-mpls-tp-cp-framework-04.txt The ITU-T comments received liaison (ref 040.02) has been resolved as follows: Comment [M1]: Need to clarify that this applies to both LSP and PW and that management plane configuration is always supported – See comment M6 on v2. Another solution for this comment would be to delete the sentence. Response: remove text requiring clarification OLD Text: Management plane functions such as manual configuration and the initiation of LSP setup are out of scope of this document. NEW Text: Management plane functions are out of scope of this document. Comment [M2]Extension may also be required for PWs (e.g. OAM configuration) which may be outside the scope of GMPLS. Proposed text change: Removed "GMPLS", add "and PW". Response: Accept change Comment [M3]Also need to consider upgrades in the context of PW configuration Proposed text change: strike "(G)MPLS enabled" Response: Accept change Comment [M4]: Similar text was proposed in the comments on v2 but was not included. Proposed text change: Note that failure or restarting of the control plane or a change in LSP ownership must not impact the operation of any protection or OAM functions which were configured by either the control plane or management plane. Response: No comment was included in the earlier liaison. Text was viewed as a statement, not proposed addition. While the proposed text is not unreasonable, we are unable to add the text in the proposed location as parallel text does not exist in RFC5654. Comment [M5]: See comment M42 on v2. Use of may implies that the CP design must support extra traffic but activation is optional. RFC5654 Requirement, i.e., extra traffic is not required in MPLS-TP Proposed text change: strike "may" add "is not required to" Response: Please see RFC2119 for the usage of "may" in the IETF context. We believe the current text is consistent with both common IETF usage of may and the text in RFC5654. Comment [M6]: The current wording of 100 and 101 implies a single control plane, in this case the requirements are contradictory, add LSP/PW to clarify the scope of each statement. Proposed text change: Add "for LSPs", strike "for MPLS-TP LSPs", add "for PWs" (leave for MPLS-TP PWs) Response: Accepted. Comment [M7]Between nodes or along the same path . Proposed text change: strike "along", add "between" Response: clarify text: OLD Text: along the same node pairs, but not necessarily the same links NEW Text: along the same nodal path, but not necessarily the same links Comment [M8]typo Response: Accepted.
