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).
