Abstract

   This document specifies Deterministic Networking data plane
   encapsulation solutions.  The described data plane solutions can be
   applied over either IP or MPLS Packet Switched Networks.

   Comment #1:  SB> An overarching comment is that the early part of the
     document is really fundamental architecture and perhaps belongs in
     the arch draft, leaving this draft to be more specific about
     solutions.  Indeed if we cannot find a single solution that maps to
     both IP and MPLS underlays I wonder if we should publish two
     specialist RFCs?

   Discussion:  One document at the beginning, split into two if/when
     needed.  Would be post adoption in any case.

   Comment #2:  SB> Whilst I think we should look for a common solution
     to IP and MPLS I do not think that this is where the DT ended up.

   Discussion:  Agree.
