Authors, I have some comments on this document. Most are strictly editorial. Note that I'm the document shepherd, see RFC 4858 for more information. - Please address my general comments on the WSON document set - in document s/Bi-Directional/Bidirectional - Abstract s/Such extensions are necessary/Such extensions are applicable drop "bidirectional LSPs, and" - Section 1 These extensions build on previous work for the control of lambda and G.709 based networks. Please add appropriate references. It seems to that it would be worth mentioning the rwa-info document and the encoding document in this section. - section 3.1 s/MUST/needs to - Section 3.3 s/MAY/can s/MAY/need to be - Section 3.4 s/MAY/can - section 3.5 title s/Out of Scope/Optical Impairments - Section 4.2: To target a specific node, this section defines a WSON_Processing object as part of the LSP_REQUIRED_ATTRIBUTE and follows procedures defined in [RSVP-RO]. The content of this object is defined in the subsequent sections. (See Section 4.3 for <RBInformation> TLV and Section 4.4 for <WavelengthSelection> TLV, respectively.) Do you mean To target a specific node, this section defines a WSON_Processing HOP Attribute TLV which is processed according to the procedures defined in [RSVP-RO]. The content of this TLV is defined in the subsequent sections. (See Section 4.3 for <RBInformation> sub-TLV and Section 4.4 for <WavelengthSelection> sub-TLV, respectively.) if yes, also need to s/WSON Processing object/WSON Processing TLV in rest of document. - Section 4.2 You need to define the Length. Perhaps. replace the whole definition: OLD The WSON Processing object encoding is defined as: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type | Length | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | ~ Value ~ | | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ NEW The WSON Processing carries sub-TLVs of the same format as a HOP Attributes TLV, as defined in [RSVP-RO]. - Section 4.3. "... PathErr SHALL be generated." Which code/value? Are you sure? Generally malformed messages don't result in a PathErr. What is an upstream node expected to do with the PathErr? How should other parsing errors be handled? What about allocation errors? - Section 4.4 I'm really confused by this sub-tlv. Is it intended to be an end to end construct, information that is used/updated hop-by-hop, or used at specific hops only? I suspect that the desire is for this to be communicated end to end and accessible at each hop. If so, it looks like then intent is for this to be carried as a TLV in the LSP_ATTRIBUTES Object. Is this correct? If so the section needs to be updated accordingly. - Section 5 I'm really not sure that this section adds anything beyond what is already stated in other documents/RFCs, and it doesn't match this documenting being a protocol specification. I can see some informative value in the third paragraph. I suggest moving just this paragraph to the end of section 4.3 and dropping the rest. - Section 6 I think this section needs to be replaced. Perhaps use the following which is based on draft-ietf-ccamp-gmpls-signaling-g709v3 This document is builds on the mechanisms defined in [RFC3473], and only differs in specific information communicated. As such, this document introduces no new security considerations to the existing GMPLS signaling protocols. See [RFC3473], for details of the supported security measures. Additionally, [RFC5920] provides an overview of security vulnerabilities and protection mechanisms for the GMPLS control plane. - Section 7 This section needs a bit of work See http://tools.ietf.org/html/draft-ietf-ccamp-gmpls-signaling-g709v3-12#section-11 for an example. Contact me off list if you think need help with specific text.
