Re: [Raw] [Detnet] WG Last Call: draft-ietf-raw-architecture-11

["Pascal Thubert (pthubert)" <[e-mail]>]

Hello Lou and all

I captured some of the meeting conclusions in one slide that I added to the presentation on architecture for DetNet / RAW tomorrow. Please let me know if you have any issue with it. We still have to discuss the new North.

Agreeing  on  terminology is often really hard - particularly when different groups come from different backgrounds and years of independent work.  6TISCH has tracks, TE/DetNet has protection paths, and more generally recovery.  I continue to view what is being described in the raw architecture is a wireless tailored form of protection (and actually not radically different from traditional 1+n protection, where outside the protection domain it is impossible to know which protection path was used.)

I don't recall the 115 discussion closing on this point.  Rereading https://datatracker.ietf.org/doc/minutes-115-raw-202211110930/ leaves me with just the opposite impression. I do see that some volunteered to work with you on a terminology alignment discussion.  Did those conversations ever happen?

I think you are definining something new - a wireless tailored protection function.  I'm not suggesting getting rid of it, just that it is described reusing existing terminology wherever possible.

Thanks,

Lou
