Hello Quan

We chatted between authors and though we agree that there are 2 parts, we believe that it is premature to split. 

This might be done in the WG process of the draft if/when the WG approves the work. Effectively DetNet has a history of splitting documents, and we think the group needs to decide what remains and how to structure it. 
At the moment, what we mostly we want is the adoption of the broad idea to define a DetNet native IPv6 signaling.

Agreed for the use cases and detailed procedures. Then again, we have ample time to do that with more brains on it as a WG effort vs. the limited author set.

Keep safe;

Pascal

> For DetNet Redundancy Information Option, it solves the same issue with
> draft-varga-detnet-ip-preof. Use cases and detailed procedures could be
> provided especially for the extended parameters.
> For DetNet Path Options, it is inspired to propose the path-oriented
> forwarding for DetNet, but other than Path-ID carried in packets, we need
> more detailed mechanisms.
> I am not sure if I understand it right or no, I suggest to divide the
> draft into two drafts discussing the Redundancy and Path separately.
