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.

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.
