A … Received changes through RFC Editor sync (changed abstract to 'RSVP-TE provides support for the communication of exclusion information during Label Switched Path (LSP) setup. A typical LSP diversity use case is for protection, where two LSPs should follow different paths through the network in order to avoid single points of failure, thus greatly improving service availability. This document specifies an approach that can be used for network scenarios where the full path(s) is not necessarily known by use of an abstract identifier for the path. Three types of abstract identifiers are specified: client based, Path Computation Element (PCE) based, and network based. This document specifies two new diversity subobjects for the RSVP eXclude Route Object (XRO) and the Explicit Exclusion Route Subobject (EXRS). For the protection use case, LSPs are typically created at a slow rate and exist for a long time so that it is reasonable to assume that a given (reference) path currently existing (with a well-known identifier) will continue to exist and can be used as a reference when creating the new diverse path. Re-routing of the existing (reference) LSP, before the new path is established, is not considered.') |

Specifically, the PAS seems like it might potentially leak information about paths, because if I am able to learn someone else's PAS values, I can tell if they are routed along the same paths as I am. Is that correct? If so, it seems like it might be useful to recommend self-encrypting PAS values so that two identical paths given to separate people have different PAS values. Also, it seems like it S 2.3 would be clearer if you factored out the algorithm for processing the XRO values from the differential treatment depending on the L bit. Perhaps you could just have one list and use [SHOULD (L=1), MUST(L=0)] or something? |

I also think that Ignas Bagdonas' OpsDir review ( https://datatracker.ietf.org/doc/review-ietf-teas-lsp-diversity-08-opsdir-lc-bagdonas-2017-08-30/ ) needs careful consideration / addressing. I almost balloted DISCUSS from them, but trust that they will be addressed. I did find much of the document well written and an easy read. The diagrams were also (surprisingly) clear. I have some nits / comments, mainly around the abstract. 1: "Resource ReserVation Protocol-Traffic Engineering (RSVP-TE)" - s/ReserVation/ReSerVation/ (otherwise the (R)RSVP would be (R)RVP) 2: " Three different mechanisms are supported how LSP diversity can be accomplished in the provider or core network: ..." - this doesn't really parse. Perhaps " Three different mechanisms providing LSP diversity in the provider or core network are supported:..." ? Not great, but ... 3: "The solution described in this document is based on the assumption that LSPs are requested sequentially, i.e., the time period between the LSP setup requests for the two LSPs may be longer (days, weeks, months)." -- may be longer than what? Perhaps "may be relatively long" or "may be on the order of days / weeks / months"? 4" "Re-routing the first LSP that may have existed for a longer period of time is not considered." - again, longer than what? Longer than the second (/ Ntn)? Longer than months? |

For … [Ballot comment] The Abstract should stand on its own; and, as such, needs to expand the "XRO" and "EXRS" acronyms (similar to the Introduction). For completeness, the definition of the "E" flag in section 2.1 probably needs to indicate that bit 0x08 is reserved, and MUST be set to 0 send, ignored on receipt. In section 3.2, on page 19, concerning the following text: If, subsequent to the initial signaling of a diverse LSP, the requested exclusion constraints for the diverse LSP are no longer satisfied and an alternative path for the diverse LSP that can satisfy those constraints exists, then: The phrasing "no longer satisfied" seems a bit incomplete, as (by my understanding) the constraints might not have been satisfied in the first place, if the L-bit was set in the initial request. I presume that, if this were to happen, you'd want to signal when a compliant path became available -- but the current text doesn't indicate that this is okay. Perhaps something like: "...are no longer satisfied (or, in the case that the initial request triggered a "Failed to satisfy Exclude Route" error subcode, remain unsatisfied), and an alternative path for..." |

The other exceptions do make sense to me, so I’m only curious about this one. |

If any part of this review is inaccurate, please let us know. We have a question about one of the actions requested in the IANA Considerations section of this document. The IANA Services Operator understands that, upon approval of this document, there are four actions which we must complete. First, on the Resource Reservation Protocol (RSVP) Parameters registry page located at: https://www.iana.org/assignments/rsvp-parameters/ the EXCLUDE_ROUTE object is C-Type 232. However, the current draft references C-Type 1. IANA Question --> Are the two registrations requested in section 4.1 intended to be inserted in the Sub-Object types subregistry for the Class Types or C-Types - 232 EXCLUDE_ROUTE registry? Second, in the Sub-object type - 20 EXPLICIT_ROUTE ? Type 1 Explicit Route subregistry of the Class Types or C-Types - 20 EXPLICIT_ROUTE registry on the Resource Reservation Protocol (RSVP) Parameters registry page located at: https://www.iana.org/assignments/rsvp-parameters/ two new registrations are to be made as follows: Value: [ TBD-at-Registration ] Description: IPv4 Diversity subobject Reference: [ RFC-to-be ] Value: [ TBD-at-Registration ] Description: IPv6 Diversity subobject Reference: [ RFC-to-be ] We note that the values used for these two registrations are requested to be the same values used in the registration for the request in Section 4.1 of the current draft. Third, in the Sub-Codes - 24 Routing Problem subregistry of the Error Codes and Globally-Defined Error Value Sub-Codes registry on the Resource Reservation Protocol (RSVP) Parameters registry page located at: https://www.iana.org/assignments/rsvp-parameters/ a single, new registration is to be made as follows: Value: [ TBD-at-Registration ] Description: Unsupported Diversity Identifier Type Reference: [ RFC-to-be ] Fourth, in the Sub-Codes - 225 Notify Error subregistry of the Error Codes and Globally-Defined Error Value Sub-Codes registry on the Resource Reservation Protocol (RSVP) Parameters registry page located at: https://www.iana.org/assignments/rsvp-parameters/ three, new registrations are to be made as follows: Value: [ TBD-at-Registration ] Description: Route of XRO LSP identifier unknown Reference: [ RFC-to-be ] Value: [ TBD-at-Registration ] Description: Failed to satisfy Exclude Route Reference: [ RFC-to-be ] Value: [ TBD-at-Registration ] Description: Compliant path exists Reference: [ RFC-to-be ] The IANA Services Operator understands that these four actions are the only ones required to be completed upon approval of this document. Note: The actions requested in this document will not be completed until the document has been approved for publication as an RFC. This message is only to confirm what actions will be performed.

Please send substantive comments to the ietf@ietf.org mailing lists by 2017-08-24. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract Resource ReserVation Protocol-Traffic Engineering provides support for the communication of exclusion information during label switched path (LSP) setup. This document specifies two new diversity subobjects for the RSVP XRO and EXRS subobjects. Three different mechanisms are supported how LSP diversity can be accomplished in the provider or core network: the signaled diversity type, indicates whether diversity is based on client, path computation engine (PCE), or network assigned identifiers. The solution described in this document is based on the assumption that LSPs are requested sequentially, i.e., the time period between the LSP setup requests for the two LSPs may be longer (days, weeks, months). Re-routing the first LSP that may have existed for a longer period of time is not considered.
