Hi Carlos, Thank you very much for your comments and suggestions. We will address them accordingly as described inline below with prefix [HC]. Best Regards, Huaimo ________________________________ From: Carlos Pignataro via Datatracker <noreply@ietf.org> Sent: Sunday, March 22, 2020 11:18 PM To: rtg-dir@ietf.org <rtg-dir@ietf.org> Cc: pce@ietf.org <pce@ietf.org>; draft-ietf-pce-stateful-pce-lsp-scheduling.all@ietf.org <draft-ietf-pce-stateful-pce-lsp-scheduling.all@ietf.org> Subject: Rtgdir early review of draft-ietf-pce-stateful-pce-lsp-scheduling-12 Reviewer: Carlos Pignataro Review result: Has Nits Hello, I have been selected as the Routing Directorate reviewer for this draft. The Routing Directorate seeks to review all routing or routing-related drafts as they pass through IETF last call and IESG review, and sometimes on special request. The purpose of the review is to provide assistance to the Routing ADs. For more information about the Routing Directorate, please see https://nam11.safelinks.protection.outlook.com/?url=http%3A%2F%2Ftrac.tools.ietf.org%2Farea%2Frtg%2Ftrac%2Fwiki%2FRtgDir&data=02%7C01%7Chuaimo.chen%40futurewei.com%7C89cb9451d2f74f854da608d7ced8e77c%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C0%7C637205303321659875&sdata=6R9jure7G95HIZQDlXO%2F27mVBVwZWR27RoFvhhpfsLo%3D&reserved=0 Although these comments are primarily for the use of the Routing ADs, it would be helpful if you could consider them along with any other IETF Last Call comments that you receive, and strive to resolve them through discussion or by updating the draft. Document: draft-ietf-pce-stateful-pce-lsp-scheduling Reviewer: Carlos Pignataro Intended Status: Proposed Standard Summary: This is a well written document, which displays iterations that improved its quality. I have no concerns with this document. I would point out a small set of questions and potential issues for the author's consideration: 5.2.1. SCHED-LSP-ATTRIBUTE TLV Can Start-Time and Duration take any value from 0 to 32-bits-of-ones? [HC]: Good catch. The value of 0 for Start-Time and Duration does not make any sense. We will restrict its use. The value of 32-bits-of-ones can be used. 9. Manageability Consideration Could these add Default values or ranges (esp. to times, seconds, etc.)? [HC]: Yes. We will introduce some default values. 10. IANA Considerations 10.1. PCEP TLV Type Indicators For the SCHED-LSP-ATTRIBUTE and SCHED-PD-LSP-ATTRIBUTE, I suggest creating Registries for the Flags: | Flags |R|C|A| What is the future's allocation policy for remaining Flags for example? Actually reading later Section 10.3 I realize they are specified there. Why are the Flags in a different section, but Opt in this section? Anyway, a nit. [HC]: We will move it into this section. IANA is requested to create and maintain a new registry "Opt" under SCHED-PD-LSP-ATTRIBUTE (TLV Type: TBD2). Initial values for the registry are given below. What is the allocation policy for Unassigned? [HC]: We will add "New values are assigned by Standards Action [RFC8126]." Value Name Definition ----- ---- ---------- 0 Reserved 1 REPEAT-EVERY-DAY Section 5.2.2 2 REPEAT-EVERY-WEEK Section 5.2.2 3 REPEAT-EVERY-MONTH Section 5.2.2 4 REPEAT-EVERY-YEAR Section 5.2.2 5 REPEAT-EVERY-REPEAT-TIME-LENGTH Section 5.2.2 6-14 Unassigned 15 Reserved What is the reason for "Section 5.2.2"? Since this are instructions for IANA, these references are not significant without the document reference. [HC]: We will change it to "This document". Appendix A. Contributor Addresses There are more than one Contributors -- why singular? [HC]: We will use plural. I hope these help, [HC]: These really help improve the quality of the document. Carlos Pignataro.
