[tsvwg] Re: 5QI to DiffServ DSCP Mapping for Slicing (was TR: [Teas] IETF 120 - TEAS WG - Session Logistics

[[e-mail]]

Hi David, all,

You raised a good point about draft-henry. I trust that authors of draft-cbs can provide some inputs here.

From where I sit, what I guess changed since draft-henry is that more and more operators are facing the same question for the realization of slices in “transport networks” (per 3GPP terminology) and how the mapping need to be realized between 3GPP/TN. The transport network leg is not within the scope of 3GPP spec. Having guidance/mapping examples would be useful for many operations out there.

Cheers,
Med

Hi Med,
[+teas list]

Thanks for the pointer – IMHO, the specific DSCP mappings also ought to be discussed in tsvwg.  Beyond the mappings, the draft contains a lot of 5G and MPLS material for which teas is likely to be a better forum.

The draft's reference to draft-henry-tsvwg-diffserv-to-qci brings up some important context.  Back when draft-henry-tsvwg-diffserv-to-qci was considered in tsvwg, 3GPP was strongly opposed to any IETF standardization (even via an Informational RFC) of QCI/5CI – Diffserv (including DSCP) mappings, especially for public (carrier) networks.  Has that 3GPP position changed since then?

Thanks, --David (a former tsvwg chair)

Hi all,

FWIW, there is a prez in TEAS that might be of your interest:

==
10) 11:00 | 10 min | Title: 5QI to DiffServ DSCP Mapping Example for Enforcement of 5G End-to-End Network Slice QoS
Draft: https://datatracker.ietf.org/doc/draft-cbs-teas-5qi-to-dscp-mapping/02/ [datatracker.ietf.org]<https://urldefense.com/v3/__https:/datatracker.ietf.org/doc/draft-cbs-teas-5qi-to-dscp-mapping/02/__;!!LpKI!mw703P4RvmYRfx-xPH7-yJVZS84FduSH16hPEyHLODfa_NjeQG559BHmUOqbS0CpFLNt7fRycvDSfT5WrjTUKIEpxilL$>

I wonder whether that discussion should happen here in tsvwg rather than teas.

Cheers,
Med
