Cancan,

Thank you very much for reviewing the drafts and provide the valuable feedback.  You are correct that the two drafts currently have some overlap in the UCMP-related sections.

The two drafts have different scopes and objectives. The AC-TE applicability draft covers broader Edge Cloud placement and traffic engineering use cases, while the PE2PE-UCMP applicability draft focuses specifically on dynamic UCMP for periodic inter-site traffic.

We prefer to keep the two drafts separate because they address different problem spaces. We will revise the overlapping sections to better clarify their respective contexts and minimize unnecessary duplication. We also welcome your input and collaboration, including joining as co-authors.

Thanks, Linda

Subject: [Onsen] Questions for draft-dunbar-onsen-ac-te-applicability-00 and draft-dunbar-onsen-ac-pe2pe-ucmp-applicability-00


Dear authors,

 I have been reviewing the following two IETF Internet-Drafts and noticed some overlapping content:

 Draft-dunbar-onsen-ac-te-applicability-00 describes two solution areas and the YANG model enhancements needed at IETF to realize them: (1) how to deploy AI models to optimal Edge Cloud sites based on network status data in YANG models; and (2) how to achieve UCMP for AI and non-AI traffic between sites. For the second point, it includes Time-Scoped UCMP Policy Enforcement for the AC segment, UCMP Enforcement for SRv6 based PE to PE segment, and Cloud-Initiated UCMP Activation API .

Draft-dunbar-onsen-ac-pe2pe-ucmp-applicability-00 describes Dynamic UCMP Load Balancing for Periodic Inter Site AI Traffic, covering UCMP Enforcement for Access Segment, UCMP Enforcement for SRv6 based PE to PE segment, and Cloud-Initiated UCMP Activation API .

It appears that the two drafts share overlapping sections on UCMP enforcement (Access/AC segment, SRv6 PE-PE segment, and Cloud-Initiated API). Could you please clarify the differences in the overlapping parts between these two documents? In addition, do you think the two drafts would be better merged into a single document?

Looking forward to your thoughts.

Best regards,

Cancan Huang
