Joel,

Indeed, there was a clear message (from what I recall from the chat comments) towards thinking of the realization of such capability in relation to the underlay and particular the routing system. 

From my side, I don't see the need to place this into the underlay as a given, while the question to realize a compute-aware on-path endpoint selection decision may well be of interest. Is that a fair statement?

Best,

Dirk

I believe I was very clear during the BoF.  I have not seen a persuasive case for why we need to use the underlay routing system to address the problem of enabling communication between end user applications and edge located compute services.

There are multiple ways to improve the application situation without burdening the underlay routing with something it does not care about.

Yours,
Joel
