[mpls] R: PSC: draft-rhd-mpls-tp-psc-priority-00

Hi Eric,
You wrote "is it appropriate to make this priority swap?"
My answer is yes, it shall be done for the reasons explained in liaison 1205, bullet 1.

You wrote "- what do we need to change?  rfc5654?  rfc4427?  "
No I don't believe it is required to change any RFC but RFC 6378

Best regards,
Alessandro

Oggetto: [mpls] PSC: draft-rhd-mpls-tp-psc-priority-00

This thread is for discussing draft-rhd-mpls-tp-psc-priority-00.  In brief, the draft proposes swapping the priorities between FS and SF-P (see section 4.3.2 of rfc6378).  This proposed swap has a long history, dating back to when PSC was an ID.  For some history, see

http://datatracker.ietf.org/liaison/1229/
and
http://datatracker.ietf.org/liaison/1234/

The questions that I think are relevant here are:

- is it appropriate to make this priority swap?
  - are there alternative approaches?
  - what do we need to change?  rfc5654?  rfc4427?
- if we don't make the change, does this expose implementation to problems?
- if we do make the change, how do we go about it?

but of course any and all discussion is welcome.

As with the other threads I'm going to leave my two cents out of this introductory email but I'll chime in when discussion starts.

eric
