We have reviewed the document and have a number of comments. In general, it is becoming less and less clear that the title of this document is accurate! SG15 now embraces a number of non-optical transport technologies including Ethernet and MPLS-TP. Although those packet-based technologies can be transmitted over optical links, they are not limited to that medium. Maybe your document should be titled "Transport Networks & Technologies Standardization Work Plan" or maybe you should remove the non-optical material. The scope text in Section 5 and 5.1 might also need revision. The IETF has not position of this, but simply draws the matter to your attention. Table 5-1 We would like to suggest the inclusion of the MPLS Working Group in this table as that working group is responsible for many elements of the support of Ethernet "carrier-class" pseudowires over MPLS and MPLS-TP networks. Section 5.6.1 begins: "MPLS OAM was originally standardized by ITU-T SG13 (Q.5/13)." Although the section goes on to list IETF standardization of MPLS OAM, it may be considered that this first sentence implies that the ITU-T developed MPLS OAM before any MPLS OAM had been developed within the IETF. This would, of course, be a misrepresentation. Therefore, we suggest that you change this first sentence to read: "Within the ITU-T, MPLS OAM was originally standardized by SG13 (Q.5/13)." Table 5-3 Architectural Aspects of MPLS-TP Add RFC 5921, RFC 5950, RFC 5960 Equipment Functional Characteristics of MPLS-TP Add RFC 5960 OAM and Protection Switching of MPLS-TP Add RFC 5860 Management Aspects of MPLS Add RFC 4221 Management Aspects of MPLS-TP Add RFC 5950, RFC 5951 Performance of ATM Add RFC 3116 Performance of MPLS Add RFC 5695 Table 7-1-2 draft-ietf-mpls-tp-framework is now RFC 5921 draft-ietf-mpls-tp-nm-req is now RFC 5951 draft-ietf-mpls-tp-survive-fwk reached revision -06 and has been approved for publication as an RFC draft-ietf-mpls-tp-oam-framework reached revision -10 and has been approved for publication as an RFC draft-ietf-mpls-tp-nm-framework is now RFC 5950 draft-ietf-mpls-tp-rosetta-stone has reached revision -03 draft-ietf-mpls-tp-data-plane is now RFC 5960 draft-ietf-mpls-tp-identifiers has reached revision -03 draft-ietf-mpls-tp-ach-tlv is now abandoned draft-ietf-ccamp-mpls-tp-cp-framework has reached revision -05 Further relevant Internet-Drafts and RFCs can be found at: http://datatracker.ietf.org/wg/ccamp/ http://datatracker.ietf.org/wg/mpls http://datatracker.ietf.org/wg/pwe3 http://datatracker.ietf.org/wg/bfd http://datatracker.ietf.org/wg/pce Table 7-4-2 draft-ietf-gmpls-ason-routing-ospf is now RFC 5787 Table 7-8 should inherit changes to Table 7-1-2 and be updated according to the document status available at the IETF working group pages as listed above. Table 8-1 entry 3. Please be aware of the work on impairment-aware routing in the CCAMP and PCE working groups. (It may be your intention that this is covered under entry 5.) Annex A might usefully refer readers to RFC 4397 and draft-ietf-mpls-tp-rosetta-stone that provide terminology mapping and have been jointly developed by IETF and ITU-T experts. We would welcome it if you shared any future revisions of this work plan with us. Adrian Farrel IETF Liaison to the IETF on the Optical Control Plane Routing Area Director
