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.

Regards,
John

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Distributed Mobility Management WG of the IETF.

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).
