Re: I-D Action: draft-ietf-dmm-tn-aware-mobility-04.txt

Hi Hannu,

In draft-ietf-dmm-tn-aware-mobility, we have referred to the 'IETF Network slice' in section 1.1 (IETF Network Slicing Terminology] and to the TEAS draft
       [I-D.ietf-teas-ietf-network-slices]
              Farrel, A., Drake, J., Rokui, R., Homma, S., Makhijani,
              K., Contreras, L. M., and J. Tantsura, "Framework for IETF
              Network Slices", draft-ietf-teas-ietf-network-slices-12<https://datatracker.ietf.org/doc/html/draft-ietf-teas-ietf-network-slices-12>
              (work in progress), June 2022.

The draft below (https://datatracker.ietf.org/doc/html/draft-gcdrb-teas-5g-network-slice-application-00<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fhtml%2Fdraft-gcdrb-teas-5g-network-slice-application-00&data=05%7C01%7Cjohn.kaippallimalil%40futurewei.com%7Ce0a68a934f0643baf11f08da689358c4%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C0%7C637937279378109706%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=RnAjvIPC93h9hu8BsxHVYT939OG1bMdyP81oJ5AQAaE%3D&reserved=0>) is new / an individual draft version 00, so I have still to follow it in detail.
A quick read indicates that the individual draft above and dmm-tn-aware-mobility have commonality in how 3GPP 'network instance' can be mapped for L2 transport (VLAN, MPLS, etc...)

When the 3GPP user plane function (5G-AN, UPF) and transport provider edge are on different nodes, a L3/IP mechanism is needed to carry that mapping (also see, section 2.5).
Only the dmm draft covers the case where the mapping is carried over L3/IP for the above case.

BR,
John

Hello Uma

I would like to remind you that TEAS WG is working on IETF slicing.
Have you looked into IETF Network Slice Application in 5G End-to-End Network Slice, https://datatracker.ietf.org/doc/html/draft-gcdrb-teas-5g-network-slice-application-00<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fhtml%2Fdraft-gcdrb-teas-5g-network-slice-application-00&data=05%7C01%7Cjohn.kaippallimalil%40futurewei.com%7Ce0a68a934f0643baf11f08da689358c4%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C0%7C637937279378109706%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=RnAjvIPC93h9hu8BsxHVYT939OG1bMdyP81oJ5AQAaE%3D&reserved=0>

Is draft-ietf-dmm-tn-aware-mobility-04.txt aligned with it?

Best regards
Hannu

Dear All,

This is just a refresh (with affiliation changes and corrected references).

Appreciate further feedback/comments.

Abstract:
   This document specifies a framework and mapping of slices in 5G
   mobile systems to transport network slices in IP, Layer 2 or Layer 1
   transport networks.  Slices in 5G systems are characterized by
   latency bounds, reservation guarantees, jitter, data rates,
   availability, mobility speed, usage density, criticality and
   priority.  These characteristics are mapped to transport network
   slice include bandwidth, latency and criteria such as isolation,
   directionality and disjoint routes.  Mobile slice criteria are mapped
   to the appropriate transport slice and capabilities offered in
   backhaul, midhaul and fronthaul connectivity segments between radio
   side network functions and user plane function(gateway).

   This document describes how a mobile network slice is mapped to a
   slice in IP or Layer 2 transport network between 3GPP provisioning
   end points.  The same mapping mechanisms apply during initial UE
   session setup and following UE mobility.  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).
