Hi Luis, Good summary. Please see below.

As part of the re-charter discussion, four use cases will be considered for supporting the proposal in which respect to ALTO extensions for operation automation. Case 1. Extensions to RFC 7971 leveraging on previous protocol extensions (e.g., cost calendar, path vector) that can make necessary new architectural and deployment considerations RFC7971 is valuable and hence an update to include the effects of protocol extensions is highly valuable. I understand that cost calendar and path vector are examples, and other extensions such as SSE can be included and we want to make sure to do a relatively comprehensive update. [Qin]: Another limitation of RC7971 is to lack multi-domain support. Therefore I feel multi-domain support should be also documented for this item to address limitation of ALTO deployment in RFC7971. Case 2. Usage of ALTO for combined compute and network selection (e.g., for optimal edge computing service placement). Does Case 2 belong to general protocol extension or operation automation? [Qin]:I think operation automation is also required in this case, i.e., how network information and compute information are aggregated. One thing I am not sure is whether Whether path vector has already supported compute information? Maybe author can clarify. Case 3. Extensions to ALTO for acting as aggregator of information from different sources (e.g., TEDB, LSP DB, etc) Case 3 is definitely a good use case supporting operation automation. Case 4. Overlay / underlay integration supported by ALTO (e.g., CDN). Overlay/underlay integration can have many aspects. So the goal is to focus on the operation automation aspect? One possibility is to define operation automation broadly, including operation automation of not only ALTO but the overall system (i.e., the integrated overlay/underlay). If this is the case, we may want to specify the scope well. [Qin]: Agree, I think this case describe ALTO interface as Network as a service interface, allow the underlay expose capability and status to the overlay, So overlay can know how to optimize the service delivery. This case looks very interesting. Looking forward to a great discussion on Friday. Richard Any comment, suggestion or indication is more than welcome.
