Hi there, I completely agree with Les here. ASLA exist already as per RFC8919, RFC8920. Example of application is here: https://datatracker.ietf.org/doc/html/draft-ietf-lsr-flex-algo-17#section-12. Generic Metrics fits the application specific paradigm.
What are we trying to accomplish here and what’s broken or is not enough other than what we already have ? dan From: Lsr <[email protected]> on behalf of "Les Ginsberg (ginsberg)" <[email protected]> Date: Wednesday, July 28, 2021 at 3:35 PM To: Tony Li <[email protected]>, Shraddha Hegde <[email protected]> Cc: "[email protected]" <[email protected]> Subject: [EXT]Re: [Lsr] Generic metric: application-specific vs application-independent Tony – IMO, you are asking the wrong question. 😊 ASLA exists to support the advertisement of attributes which can be used in application specific ways. In any particular deployment case, a given attribute advertisement might be used by one app, multiple apps, or all apps. ASLA allows to unambiguously support all of these cases with a single advertisement encoding format. The correct question to be resolving here is indeed the question which has been discussed in an earlier thread: Is Generic Metric a link attribute which can have application specific use cases? I think the question to that is unquestionably “yes”. That should be enough (IMO of course) to close the discussion.

I think that a better question is: Is there a usecase that is so overwhelmingly compelling that the added complexity of ASLA is warranted?

All the use cases that I heard from network operators while writing the draft could be solved using generic-metric advertised in an application-independent way. I am looking for clear description of use cases that would benefit from advertising generic metric in an application specific way. Can any one provide such a usecase?
