111IETF 70: MEXT Working Group – Virtual Home Network Support in Mobile IPv6


Meeting Plan

Session Logistics, note taker(s), etc.

IGMP/MLD Requirements discussion (Brian, Behcet) [20 min]

Mobility Protocol - PMIPv6 Requirements discussion ( Dirk ) [20 min]

Update on Solution Drafts (Brian, Behcet) [10 min]

Next Steps and Action Items [10 min]


Meeting Plan The goal is to work on the drafts

Ask for volunteers to work and recruit authors

The authors get back and come with an improved revision by IETF 75

Session notes will be distributed to the list

Phase 2 Requirements

MN initiated activation of additional MCBCS sessions while delivering the MCBCS program.

Dynamic multicast group support enabling applications like multi-player games.


3GPP EPS PS

Text contributed by Dirk

3GPP eMBMS work will be done in Release 9

Please volunteer to contribute text


Wi-Fi PS

This section currently empty



IGMP/MLD PS

One issue is message authentication

Another issue is IGMP/MLD unsolicited group reports

Yet another issue is the user authentication Please refer to Bill’s slides


PMIPv6 PS Draft

http://ietfreport.isoc.org/all-ids/draft-deng-multimob-pmip6-requirement-01.txt

This draft needs to be rewritten

Feedback obtained from IETF 73 BoF

Emphasis on traffic requirements

Do we need PMIPv6 protocol changes to support multicast?

Do we need any normative behavior at MAG?

Do we need any normative behavior at LMA?


PMIPv6 PS Draft

In PMIPv6, for MN MAG is the default router but MN does not know LMA

Do we need any handover support?

Based on all of the above come up with a new draft


We need to get feedback from netlmm chairs

We need to get feedback from netlmm people


PMIPv6 PS

Please refer to Dirk’s slides


Solution Drafts

We have 3-4 PMIPv6 solution drafts

We have one MLD/IGMP extension draft

We have several MIPv6/HMIPv6 solution drafts

We have one MIPv4 solution draft

We have one FMIPv6 solution draft

We have one Nemo solution draft

We have other solution drafts


Thank You
