COMMENT:
----------------------------------------------------------------------

(1) I may have completely missed the point of this document; what is it?  More
importantly, what is this document specifying?  Why is it on the Standards
Track?

As I see it, this document says that IP flows can be carried over MPLS -- ok,
specifically over DetNet MPLS.  The mapping of IP flows to an MPLS LSP is no
different in DetNet MPLS when compared to "plain" MPLS...nor is it different
for IP vs DetNet IP flows -- from §4.2:

   Mapping of IP to DetNet MPLS is similar for DetNet IP flows and IP
   flows.  The six-tuple of IP is mapped to the S-Label in both cases.
   The various fields may be mapped or ignored when going from IP to
   MPLS.

At best, it seems to me that this document could be Informational.

(2) It looks like this document should be tagged in the Datatracker as (also)
replacing draft-ietf-detnet-dp-sol-ip.

(3) s/both Non-DetNet and DetNet IP packet/both Non-DetNet and DetNet IP packets
