Hi all, We updated the draft based on the comments in the meeting and other feedback on this draft (see links below).
The changes include: - Teas slicing terms to align and use the same terminology across the IETF slicing aspects. This was one of the main comments on the draft. - clarified MTNC used in this draft is defined as "logicInterfaceId" in 3GPP (see section 2.2) and that this draft uses concepts in 3GPP but does not define it. - also revised TNF (Transport Network Function) to TNO (Transport Network Orchestration) to align with "orchestration" in teas slicing - several changes to clean up the text and addresses this comment from the meeting. At this point, the authors have addressed all the comments from the group and would like to get a few thorough reviews and progress the draft.

This draft is a work item of the Distributed Mobility Management WG of the IETF. Title : Mobility aware Transport Network Slicing for 5G Authors : Uma Chunduri John Kaippallimalil Sridhar Bhaskaran Jeff Tantsura Praveen Muley Filename : draft-ietf-dmm-tn-aware-mobility-05.txt Pages : 27 Date : 2022-10-19 Abstract: Slices in a 5G system should be identified and mapped to the corresponding transport network underlay segments to provide the capabilities requested by the 5G customer. One set of slices in a 5G system correspond to resources and connectivity to carry signaling and data plane packets across a distributed infrastructure that make up the 5G system, for example, distributed entities of a radio network (gNB). Another set of 5G slices represent resource and connectivity capabilities offered by the 5G system to its end users (UE) for the lifetime of a session including UE mobility. Both depend in part on multiple transport network slice segments with requirements that include bandwidth, latency, and criteria such as isolation, directionality, and disjoint routes. This document describes how a 5G slice is mapped to a slice in IP or Layer 2 transport network for both above cases, including scenarios where the 5G customer network is separated from the provider transport network by an intermediate network. Mobile slice criteria are mapped to the appropriate transport slice and capabilities offered in backhaul, mid-haul and fronthaul connectivity segments between radio side network functions and user plane function(gateway). Applicability of this framework and underlying transport networks, which can enable different slice properties are also discussed. This is based on mapping between mobile and transport underlays (L2, Segment Routing, IPv6, MPLS and IPv4).
