Cheng,

Thank you very much for the suggestions.
Here are the resolutions to your suggestions:

4.6.  Service-Oriented Capability Sub-TLV

   The service-oriented capability Sub-TLV is for distributing
   information regarding the capabilities of a specific service in a
   deployment environment.  Depending on the deployment, a deployment
   environment can be an edge site or other types of environments.  This
   information provides ingress routers or controllers with the
   available resources for the specific service in each deployment
   environment.  It enables them to make well-informed decisions for the
   optimal paths to the selected deployment environment.  Currently, the
   Sub-TLV only has an abstract value derived from various metrics,
   although the specifics of this derivation are beyond the scope of
   this document.  Importantly, this value is significant only when
   comparing multiple data center sites for the same service; it is not
   meaningful when comparing different services, meaning the capability
   value relevant to Service A cannot be directly compared with that for
   Service B.  Future enhancements may expand this sub-TLV to include
   more types of metrics or even raw data that represents direct
   metrics.  This information is important in 5G network environments
   where efficient resource utilization is crucial for enhancing
   performance and service quality.

               Figure 6: Service-Oriented Capability Sub-TLV

   - ServiceOriented Cap:  (Service-Oriented Capability) Sub-type=5
      (specified in this document).

   - Resource Identifier :  a logical term used to represent various
      types of resources, such as compute, network, power, or others,
      within the site reachable by the NLRI.  This identifier is
      consistent across all edge DCs and is determined by the specific
      deployment.  The purpose of the Resource Identifier is to indicate
      that the Service Oriented Capability Value pertains specifically
      to the resource identified by the Resource Identifier, which is
      carried in the ServiceOriented Cap Sub-TLV.


If we don't hear any objection from the IDR group, we can close your  GitHub issues.

Thanks, Linda

Hi Authors,

When I reread the draft, I find out that we can make some enhancements of the drafts, especially about the part of service-oriented part.
My comments are recorded here:

1.     https://github.com/ietf-wg-idr/draft-ietf-idr-5g-edge-service-metadata-14/issues/23

2.     https://github.com/ietf-wg-idr/draft-ietf-idr-5g-edge-service-metadata-14/issues/24

Thoughts?

Thanks,
Cheng
