I would note that it seems a little odd to do this work when we do not
have agreement on what the exposed properties are of an IETF Network
Slice (see the TEAS discussion), much less how packets are mapped to them.
Yours,

Hi Uma et all,
Thanks for putting together this draft to describe the framework for
mapping the slices in 5G mobile systems to transport slices in IP
towards the UPF. This framework is valuable and we are actually looking
for further extensions of the TN characteristics in non-mobility domain
(SD-WAN) and that is being worked out to be submitted in RTG WG.
I would also request you to consider the Security Characteristics in
addition to the current Transport Path characteristics. Preserving the
security characteristics in non-mobility SD-WAN domain would be an
important aspects. My suggestions would be to extend the current SST for
secure traffic. As a result, it would be good if we can define
additional UDP Source Port range to capture the Security characteristics
for the current service types.
I would be happy to share more context on the use cases and discuss
further on the approaches.
Regards,
Kausik

Dear DMM experts,
This version is a refresh but all comments received (offline and during
the presentation at IETF106) were addressed.
Any further comments/suggestions are most welcome.

Abstract:
This document specifies a framework and mapping from slices in 5G
mobile systems to transport slices in IP and Layer 2 transport
networks. Slices in 5G systems are characterized by latency bounds,
reservation guarantees, jitter, data rates, availability, mobility
speed, usage density, criticality and priority should be mapped to
transport slice characteristics that include bandwidth, latency and
criteria such as isolation, directionality and disjoint routes.
Mobile slice criteria need to be mapped to the appropriate transport
slice and capabilities offered in backhaul, midhaul and fronthaul
connectivity segments between radio side network functions and user
plane function (gateway).
This document describes how mobile network functions map its slice
criteria to identifiers in IP packets that transport segments use to
grant transport layer services. This is based on mapping between
mobile and IP transport underlays (IPv6, MPLS, IPv4, Segment
Routing). Applicability of this framework and a new transport
network underlay routing mechanism, Preferred Path Routing (PPR),
which brings slice properties and works with any underlying
transport
(L2, IPv4, SR and MPLS) is also discussed.
Please note that it may take a couple of minutes from the time of
