Hi WG,
After reviewing the latest version, I consider this a useful methodology for
selecting an eligible candidate path, depending on the specific service
requirements.
Path reliability and congestion adjustment are common challenges in service
deployment.
Path reliability can be achieved through BFD detection of specific segment
lists in SR Policy.
Currently, there is a lack of automatic switchover mechanisms for SR Policy
paths during congestion, and this document effectively addresses this issue.
Section 4.2 clearly defines the forwarding quality model for SR Policy, and it
is recommended to further supplement the YANG definitions in subsequent work.
Thanks,
wisdom

Dear Chairs and WG,
Thank you for the valuable feedback following our presentation at IETF 124. We
would like to offer some clarification to ensure our draft's purpose is
properly understood.
In our latest revision, we have referenced
draft-karboubi-spring-sr-policy-eligibility, though we wish to emphasize that
the two drafts serve distinctly different purposes. The eligibility draft
introduces new concepts for path qualification, while our draft focuses
specifically on defining a mechanism for path selection and switching based on
forwarding performance metrics such as latency, jitter, and bandwidth. Our
approach predefines quality requirements for SR policies and enables rapid path
selection or switching when real-time monitoring indicates these requirements
are no longer met. The reference to eligibility is included to maintain
compatibility with the SR Policy architecture defined in RFC 9256.
We believe there is no significant overlap between our draft and
eligibility draft and see value in advancing them independently. We would
appreciate if the chairs can give the guidance on how to proceed with our
draft. Additionally, we have formally requested an adoption call during our
presentation and would be grateful if the chairs can help to schedule this.
Welcome all comments and suggestions regarding our draft and look forward to
continued feedback from the working group.
Best regards,
Yisong on behalf of co-authors
