IETF-81 mobopts minutes
Mobopts Research Group Meeting, IETF81, Québec City
Room 2103, Session 2011-07-28, 900-1130
Chairs: Rajeev Koodli and Suresh Krishnan

1. Introduction

-Chairs presented themselves and started discussion about the way to
 move forward

-5 IRTF RFCs published so far reflect WG’s work

-Timely reviews are needed – mainly to make it attractive for academic
 researchers

-Comment: Mobile IPv6 does not provide a critical researcher
 mass. Chairs believe 10-15 researchers should be a good start for the
 group.

-Lars Eggert (IRTF Chair) comments: 

* Paying an academic trip to IETF is not a solution, the award is
  given to max 0-2 papers per meeting

* Some of the proposed topics are out of IP mobility scope, 
  Question: we need a new WG? Recharter?

* We definitely want new people to join and contribute

* How to convince academic researchers since publishing RFCs is not
  part of their job (how to reconcile IRTF and academic publication)

- Yuri commented on producing more survey type documents

- Lars: people should bring their work to help rechartering the
  RG. 
  Note: RG has not yet been rechartered- motivation still needs to
  come (maybe in 2-3 IETF meetings)

Lars’s  list for a RG survival or recharter criteria:
an RG should ..
-consist of a sizeable diverse group
-clearly state open research challenges
-consist of researchers (not just engineers)
-be continuous work as opposed to bursty

Challenge: find research areas-closely related-that have a researcher mass!


2. Opportunistic mobility using MP-TCP 
Presenter : Marcelo Bagnulo 

-Sri’s comment: session persistence is needed only for a few
 applications
-Discussion about open question of how to optimize the sub flows
 (without getting the application involved or extended API)

3. Using LISP for mobility
Presenter: Dino Farinacci

-presentation is not part of LISP charter-it is an individual draft
-idea: mobile device be a server-no carrier dependency-roam without
 dropping packets-same IP@, this would open up the way for new
 services
-VM mobility example, LISP-MN solution: the phone is a LISP site
-ex: RLOC mapped with geo coordinates
*had to cut discussion period (to be taken on the list?)

4. Mobility management, privacy, and other issues in vehicular
networking
Presenter: Sandra Cespedes

-Author asked to send more info and details of scenarios used on the
 list
-Current work: looking into 802.11p and its IPv6 support

5. Distributed Mobility Management with PMIPv6
Presenter: Carlos Bernardos

Chairs asked to move quickly to describe future work: 
-some new options to be defined-authors are working on implementation


6. Mobility Support by the Common API for Transparent Hybrid Multicast
Presenter: Thomas Schmidt

-prototype does not include mobility yet, but authors are working on it
-authors call to join the project website (see slides)

7. Mobility in 4G+ networks
Presenter: Charles Perkins

Problem statement: 3GPP does not follow IETF work: views it as too
slow
Comment about FMIP: FMIP assumes a topology that 3GPP does not have
Overall goal: enable easier evolution of IETF solutions.
