["Tim Szigeti (szigeti)" <[e-mail]>]

Regarding:


draft-szigeti-tsvwg-ieee-802-11 - Document Shepherd: TBD Mapping to 802.11

- Discussed at Prague IETF (Summer 2014) Topic thought to fall within TSVWG charter

-  No call issued for adoption at this time.

Chair Note: Does this need to reference RC4594 or an update to that spec.?



draft-szigeti-tsvwg-ieee-802-11 extensively references RFC 4594; and if/when RFC 4594 is updated, then we’ll update our references accordingly.



DUE: Please discuss on the TSVWG list.

If there’s no other questions/concerns for this draft, I’d like to call for adoption.

TIA.

Shepherd: David)

Revised ID needed to address congestion control and UDP Zero Checksum for IPv6.  Revised text has been adapted from MPLS-in-UDP RFC 7510, but needs further adaptation for GRE (vs. MPLS).

July 2015 - Scope of deployability discussed in Prague (meeting and

hallway) - decision is to proceed with 2 applicability scopes - general Internet and well-managed Operator Network ID submitted for Yokohama (probably not final text, but initial stab at

2 applicability scopes)

draft-ietf-tsvwg-diffserv-intercon - Info- Document Contact: David (Document Shepherd: Gorry)

formerly: draft-geib-tsvwg-diffserv-interco DiffServ interconnection classes New ID presented in Atlanta, IETF-85.

ID presented in Orlando, IETF-86, Mar 2013. Mar 2014, intended scope unclear at IETF London Adoption call to be considered, but scope needs to be first refined and a revised draft is necessary to avoid implications of broader applicability.

July 2014 - ID presented in Toronto. Strong hum of support to work on this, but a revised draft is needed first.

WG adoption call completed 2014-12-01.

March 2015: Draft got waylaid by a strong request to include a Scavenger class.

July 2015: Prague meeting discussion of scavenger class is inconclusive.

  Do need to map *all* RFC 4594 Diffserv classes.  Revised ID submitted for Yokohama. Expected response to "Scavenger class" topic is "Send Draft!"

Chairs Note: WGLC soon.
