Hi，Linda,
Thank you for your feedback.
If the access link between PE and cloud Gateway has unlimited bandwidth, do we
need to use any API?
Best regards

Subject: Re: [neotec] Re: Feedback Wanted_ Is Attachment Circuit YANG
Sufficient for Neotec Use Case_
Xueting,
You have raised a good question.
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.
Linda

Hi Linda,
In this case， how to adjust network priority to accommodate AI flow? What API
are available? What your models are available?

Med,
Following your suggestion during IETF 122 for us to take a simple Neotec use
case and "do our homework" by applying existing IETF YANG models—specifically
the Attachment Circuit model— we’ve completed an initial exercise and
documented it in the following draft:
"Applicability of Attachment Circuit and TE YANG Models to a Neotec Use Case"
https://datatracker.ietf.org/doc/draft-dunbar-neotec-ac-te-applicability/
Applying AC and TE YANG Models to Neotec Edge AI Use Case
This document explores how existing IETF YANG models, specifically the
Attachment Circuit (AC) and Traffic Engineering (TE) topology models, can be
applied to support a representative Neotec use case involving dynamic AI model
placement at Edge Cloud sites. 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
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.
Best regards,
Linda
