Hi,

We submitted version 07 of the dmm-tn-aware-mobility draft and links are found in the attachment.

All the comments and changes requested from reviews and comments in the last meeting are addressed (details below).



We would like to request dmm colleagues to please read this document and comment.

The authors believe that all aspects are now addressed and ready to progress to last call (after reviews from the group and chairs).



Some specific notes on the changes:

1.       Comment on "Mobility Aware"-ness:
This was introduced in the draft very early based on the thinking about transparently handling slices during initial setup and following handover (well before teas wg started work on slicing).
However, with the changes in 3GPP stds it has lost relevance and I have removed all references - except when it is part of the draft title " Mobility aware Transport Network Slicing"
To resolve, we have clarified with the following:
"  The slice mapping proposed here is supported transparently when a 5G user device moves across 5G attachment points and session anchors."

2.       General cleanup and revision:
The comment in dmm wg and from chair reviews was that this draft was not easily readable, lots of duplication, etc.
Based on this, we have removed duplication, text that has been superceded by concepts in teas and revisions to 3GPP standards (28.xxx management plane )

3.       Alignment with teas:
This draft is now fully aligned with concepts and related 5G slicing drafts in teas wg



BR,

John

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.
