For a detailed response, please see the reply below. Thanks, Changwang -----邮件原件----- 发件人: [email protected] <[email protected]> 发送时间: 2026年5月6日 20:15 收件人: [email protected]; [email protected]; linchangwang (RD) <[email protected]>; [email protected] 抄送: [email protected]; [email protected]; [email protected]; [email protected]; [email protected]; [email protected] 主题: Re: AUTH48: RFC-to-be 9972 <draft-ietf-grow-bmp-bgp-rib-stats-17> for your review Authors, While reviewing this document during AUTH48, please resolve (as necessary) the following questions, which are also in the source file. 1) <!--[rfced] We had the following questions about the Terminology section: a) We notice that some entries in the Terminology section include quotes from their defining documents while others do not. Should this be made uniform? [Changwang] Maintain consistency. Revise as follows: OLD: Post-policy Adj-RIB-In: As defined in Section 2 of [RFC7854]. NEW: Post-policy Adj-RIB-In: As defined in Section 2 of [RFC7854]: | The result of applying inbound policy to an Adj-RIB-In, but | prior to the application of route selection to form the Loc- | RIB. OLD: Pre-policy Adj-RIB-Out: As defined in Section 3 of [RFC8671]. Post-policy Adj-RIB-Out: As defined in Section 3 of [RFC8671]. NEW: Pre-policy Adj-RIB-Out: As defined in Section 3 of [RFC8671]: | The result before applying the outbound policy to an Adj-RIB- | Out. This normally would match what is in the local RIB. Post-policy Adj-RIB-Out: As defined in Section 3 of [RFC8671]: | The result of applying outbound policy to an Adj-RIB-Out. This | MUST convey to the BMP receiver what is actually transmitted to | the peer. OLD: Loc-RIB: As defined in Section 1.1 of [RFC4271]: | The Loc-RIB contains the routes that have been selected by the | local BGP speaker's Decision Process." Note that the Loc-RIB | state as monitored through BMP might also contain routes | imported from other routing protocols such as an IGP or local | static routes. NEW: Loc-RIB: As defined in Section 1.1 of [RFC4271]: | The Loc-RIB contains the routes that have been selected by the | local BGP speaker's Decision Process. Note that the Loc-RIB state as monitored through BMP might also contain routes imported from other routing protocols such as an IGP or local static routes. OLD: Route: As defined in Section 1.1 of [RFC4271]. NEW: Route: As defined in Section 1.1 of [RFC4271]: | A unit of information that pairs a set of destinations with the | attributes of a path to those destinations. b) We do not see any uses of Monitoring Station in this document. Please review if updates to the following text should be made. Original: The terms "Producer" and "Collector" are equivalent to "Monitored Router" and "Monitoring Station", respectively. --> [Changwang] Here it simply means that Collector is equivalent to Monitoring Station, without the need for a Monitoring Station to appear. No modifications are required. 2) <!--[rfced] Do uses of "per-" apply to both AFI and SAFI? Note that more instances occur throughout the document. 【Changwang] Yes, as described in RFC7854/RFC9069, it should be Per-AFI/SAFI. Note also that, for this instance, as AFI and SAFI are marked as well-known abbreviations, it may actually be easier for the reader if the expansions were removed: Original: ...Global Statistics and Per-Address Family Identifier (AFI)/Subsequent Address Family Identifier (SAFI) [RFC4760] Statistics. Perhaps: ...Global Statistics and Statistics per-AFI or per-SAFI (see [RFC4760]). --> 【Changwang] If directly abbreviated, it is recommended to change it to the following: NEW: ...Global Statistics and Per-AFI/SAFI [see RFC4760] Statistics. 3) <!--[rfced] Is the switch between singular and plural in these sentences intentional? a) a statistic vs. statistics Original: Both a Global Statistic and its corresponding Per-AFI/ SAFI Statistics can be reported simultaneously. Perhaps: Both Global Statistics and and their corresponding Per-AFI/ SAFI Statistics can be reported simultaneously. 【Changwang] I agree with the above modifications. b) AFI/SAFIs Original: The Per-AFI/SAFI Statistics apply only to the AFI/SAFIs that a BGP speaker supports and negotiates with its peer. Perhaps: The Per-AFI/SAFI Statistics apply only to the AFIs/SAFIs that a BGP speaker supports and negotiates with its peer. Note: even when not preceded by "Per", it may be beneficial to clarify the use of the slash character. Are these either/or relationships or and relationships? If it has a special meaning, it may be good to define AFI/SAFI in the Terminology section. --> 【Changwang] Please modify as follows: OLD: The Per-AFI/SAFI Statistics apply only to the AFI/SAFIs that a BGP speaker supports and negotiates with its peer. NEW: The Per-AFI/SAFI Statistics apply only to the AFI/SAFI that a BGP speaker supports and negotiates with its peer. 4) <!--[rfced] We plan to reformat the following text but have waited as there were so many uses, we felt it would clutter the diff file. Original: ...formatted as: 2-byte AFI, 1-byte SAFI, and a 64-bit Gauge. Perhaps: ...formatted as a 2-byte AFI, a 1-byte SAFI, and a 64-bit Gauge. Note that we will update the following similar use (many instances exist) to appear as above unless we hear objection. Original: The value is structured as: 2-byte AFI, 1-byte SAFI, followed by a 64-bit Gauge. Perhaps: The value is structured as a 2-byte AFI, a 1-byte SAFI, and a 64-bit Gauge. --> 【Changwang] I agree with the above modifications. 5) <!--[rfced] Should the following update be made? Original: The stats type 0 is a 32-counter which is a monotonically increasing number... Perhaps: Stats type 0 is a 32-bit counter that is a monotonically increasing number... --> 【Changwang] I agree with the above modifications. 6) <!--[rfced] We see both "invalidated through the ROA of RPKI" for Types 35, 36, 41, and 42 in Section 3.2 and "invalidated after verifying route origin AS number through the ROA of RPKI" for the same types in Section 8. Please let us know if/how these should be made uniform. --> 【Changwang] Change it to be consistent with the definition of Section 8. 7) <!--[rfced] Is there any issue with using both RECOMMENDED and SHOULD in the same sentence? Original: ...it is RECOMMENDED that BMP producers capable of generating both (Types 7 and 18) or (Types 9 and 19) BMP statistics SHOULD transmit both corresponding types simultaneously. Perhaps: ...it is RECOMMENDED that BMP producers capable of generating both (Types 7 and 18) and (Types 9 and 19) BMP statistics transmit both corresponding types simultaneously. --> 【Changwang] I agree with the above modifications. 8) <!--[rfced] Please rephrase "absent policy otherwise" in the following: Original: For backward compatibility, and absent policy otherwise... Perhaps: For backward compatibility, and absent any other policy... --> 【Changwang] I agree with the above modifications. 9) <!--[rfced] This list is not of a parallel structure. How may we update? Original: To avoid adversely impacting the restart process, a BMP statistics producer MAY choose to sample this value at a lower frequency, buffer updates, or temporarily suspend reporting for this type during the most critical phases of a switchover. Perhaps: To avoid adversely impacting the restart process, a BMP statistics producer MAY choose to sample this value at a lower frequency, sample it at buffer updates, or temporarily suspend reporting for this type during the most critical phases of a switchover. --> [Changwang] "sample..., buffer..., or temporarily suspend..." NEW: To avoid adversely impacting the restart process, a BMP statistics producer MAY choose to sample this value at a lower frequency, buffer the updates, or temporarily suspend reporting for this type during the most critical phases of a switchover. 10) <!--[rfced] We had the following questions/comments related to the IANA Considerations section: a) We will communicate any updates to the descriptions of the Stat types to IANA upon the completion of AUTH48. [Changwang] Agreed. b) We will update the format of the list to instead appear as a table. We have kept as is for now in order to facilitate diff review. Please let us know any objections. --> [Changwang] Agreed. 11) <!-- [rfced] Would you like the references to be alphabetized or left in their current order? --> [Changwang] alphabetized. 12) <!--[rfced] We note that the following terms may be used inconsistently throughout the document. Please review these terms and let us know if/how they may be made consistent. Stat Type vs. stat type vs. stats type (note RFC 7854 does not use stats type) [Changwang] Stat Type. BMP Statistics Report Message vs. BMP statistics message [Changwang] BMP Statistics Report message. Statistic vs. statistic (when used by itself) [Changwang] statistic. Gauge vs. gauge [Changwang] Gauge. Type vs. type (e.g., Type 27 vs. type 27) [Changwang] Type 27. statistic type vs. statistics types (various casing) - singular or plural? --> [Changwang] statistics types. 13) <!--[rfced] We had the following questions related to abbreviation use throughout the document: a) We see several instances of AS number. May we make these ASN instead (for Autonomous System Number)? --> [Changwang] Agreed, please make the changes uniformly. 14) <!-- [rfced] Please review the "Inclusive Language" portion of the online Style Guide <https://www.rfc-editor.org/styleguide/part2/#inclusive_language> and let us know if any changes are needed. Updates of this nature typically result in more precise language, which is helpful for readers. Note that our script did not flag any words in particular, but this should still be reviewed as a best practice. --> [Changwang] Reviewed, no modifications needed. Thank you.
