Xueting, The APIs for Cloud Manager (e.g. Kubernetes) to request full bandwidth across the entire 3 segments (Edge -PE, PE-PE, PE-Edge) during result aggregation or synchronized event analysis are still needed. Probably the network controller for the segment Edge-PE doesn’t need push any requests to the edge PE using AC YANG model.
What do you think?

If the access link between PE and cloud Gateway has unlimited bandwidth, do we need to use any API?

We recently added our exercise on Dynamic UCMP Load Balancing for Periodic Inter Site AI Traffic: https://datatracker.ietf.org/doc/draft-dunbar-neotec-ac-te-applicability/ to address the following use case scenario: AI inference modules are deployed across four Edge Cloud sites to support distributed city surveillance. These modules periodically exchange large volumes of data, for instance, during result aggregation or synchronized event analysis. These data exchanges are not continuous but are periodic and event driven, requiring guaranteed bandwidth and low latency for short time windows. Section 5 studies using existing YANG models to achieve the desired result. Section 6 identified the gaps. Please let us know if we missed anything.

The use case, derived from China Telecom's Neotec side meeting at IETF 122, involves selecting optimal Edge locations for real-time AI ... datatracker.ietf.org<http://datatracker.ietf.org/> Our goal with this draft is to evaluate whether the AC and TE YANG models are sufficient to support the selected use case, and to identify any potential modeling or architectural gaps. This is intended as an exploratory step to evaluate whether there is substantive, standards-relevant work that could justify a Neotec WG. We would greatly appreciate your feedback: Does this exercise align with what you envisioned? Are we on the right track? Any guidance or suggestions on how to refine the framing would be greatly appreciated. Cc'ing the opsawg mailing list here in case others would like to help us evaluate the approach and share perspectives on the usefulness of this line of inquiry.
