[DMM] Re: WG Last Call: draft-ietf-dmm-tn-aware-mobility-22 (Ends 2025-10-30)

[Kaippallimalil John <[e-mail]>]

draft-ietf-dmm-tn-aware-mobility provides a solution to support the capabilities offered by 5G slices across IP transport networks that backhaul the traffic.
As an author, I believe this draft is ready for publication.

Best Regards,
John

DMMer,

Let me remind you that the mobility-aware transport draft is now in WGLC. It will end on Oct. 30, so please review the draft.
You can use this thread to send your feedback.

Cheers,

This message starts a 2-week WG Last Call for this document.

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 IP transport network 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 transport network
   slices using UDP source port number of the GTP-U bearer when the IP
   transport network (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.
