Dear Jungha and team and all,

I think the document addresses important and interesting issues.

I agree with Thorsten Dahm that it lists problems (generally in the form
of requirements) and misses solutions.

But for me, it also misses an architectural context for the challenges
that are highlighted by the document.

For example, the discussion of latency is really about a requirement. It
would be helpful to understand more about the challenge: Where does the
important delay and jitter come from?  Is it in the wireless access or
is due to potentially high traffic loads in the network infrastructure
at the edge?  Or is the bottleneck in coordinating resources needed for
edge processing?   Perhaps working through these sorts of questions
would highlight where the most useful directions are?

Of course, the answers might be different for different architecture
models of the network and the edge functionality: A RPL-based network
operating in unlicensed spectrum and connecting via home WiFi to edge
services being provided to users spread over a large geographic area
might be quite different from a network that uses a mobile operator's
radio access network to connect to edge services for a factory
environment.  Perhaps the use cases in section 5 would be helpful in
focusing on a small number of representative architectures?

Thanks and best regards,
