Abstract:

   Network slicing in 5G enables logical networks for communication
   services of multiple 5G customers to be multiplexed over the same
   infrastructure.  While 5G slicing covers logical separation of
   various aspects of 5G infrastructure and services, user's data plane
   packets over the Radio Access Network (RAN) and Core Network (5GC)
   use IP in many segments of an end-to-end 5G slice.  When end-to-end
   slices in a 5G System use network resources, they are mapped to
   corresponding Transport Network (TN) slice(s) which in turn provide
   the bandwidth, latency, isolation, and other criteria required for
   the realization of a 5G slice.

   This document describes mapping of 5G slices to TN slices using UDP
   source port number of the GTP-U bearer when the TN slice provider is
   separated by an "attachment circuit" from the networks in which the
   5G network functions are deployed, for example, 5G functions that are
   distributed across data centers.  The slice mapping defined here is
   supported transparently when a 5G user device moves across 5G
   attachment points and session anchors.
