Hi all,

Please find the link to a new version of the dmm-tn-aware-mobility draft.
This revision adds clarification that transport slices in this draft may be between 5G user plane or control plane entities.
Also added reference to rtgwg draft that discusses how a 5G flow gets complementary slice handling in the IP service network (N6 in 3GPP terms).

Thanks to Linda for a thorough review of the draft and Sridhar for the updates.

Regards,
John

   Title:   Mobility aware Transport Network Slicing for 5G

Abstract:

   Network slicing in 5G supports 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 services, user's data plane packets over the
   radio access network (RAN) and mobile core network (5GC) use IP
   transport in many segments of the end-to-end 5G slice.  When end-to-
   end slices in a 5G system use IP network resources, they are mapped
   to corresponding IP transport network slice(s) which in turn provide
   the bandwidth, latency, isolation and other criteria requested by the
   5G slice.

   This document describes mapping of 5G slices to IP or Layer 2
   transport network slices when the IP transport network (slice
   provider) is separated from the networks in which the 5G network
   functions are deployed, for example, 5G functions that are
   distributed across data centers.  The slice mapping proposed here is
   supported transparently when a 5G user device moves across 5G
   attachment points and session anchors.
