Hi all,

I'd like to mention the following new draft:

Title:  Enhancing Mobile IPv6 Route Optimization Mode with Secure Social Dimension
	
This memo describes an enhancement to Mobile IPv6 route optimization mode which 
is derived from introducing a social dimension within the home network.

[MEXT] NEXTEXT2 BOF

To the Chair and authors of the NEXTEXT2 BOF in particular,

I am pleased to see the consideration of the challenges of multi-layer
mobility being considered here. I support the idea of considering, as the
draft authors suggest below, 

Layer 2 mobility models (independent of L3 methods)
- Because these could support models with either network based global
mobility (such as PMIP) or client based mobility (CMIP) or independent local
mobility without the "L3 methods." Although the latter might apparently seem
to indicate no need to improvements in IETF, this is not necessarily the
case. This is because there could be (I believe there is) demand for layered
approaches to mobility wherein a service provider or entity might want to
layer mobility on top of mobility. Although such methods could be made to
work off the shelf, the demand for fast mobility (such as FMIP) could be
difficult to accomplish without cross-layer signaling.

Hybrid Layer 2/3
- I'm not sure how this differs from the above. If we assume an independent
L2 model (CAPWAP, LWAP, L2TP, etc.) L3 would, by definition -- not "know"
about the underlying L2 mobility. Is hybrid to mean that the layers MUST of
necessity know to work together or CHOULD/SHOULD know. This might be the
same as what I describe above. My only comment is that I think it is helpful
to both support independent L2 from L3, but also allow cross-layer signaling
to assist or expedite event handling

Layer 3 (independent of L2 technologies)
- Still quite valuable when being applied across multiple ran/wireline
technologies
- As the above comments suggest, even where there is "apparently" L3

Re: [MEXT] Moving forward with MEXT documents - review of draft-ietf-mip6-hareliability-04

Hi Arnaud,

I submitted the new version (-05).
Most of your comments were solved in this version.

Please review it and confirms the update (see the inline messages, I  
list up the changes).

[MEXT] I-D Action:draft-ietf-mip6-hareliability-05.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Mobility EXTensions for IPv6 Working Group of the IETF.

	Title           : Home Agent Reliability Protocol
	Author(s)       : R. Wakikawa
	Filename        : draft-ietf-mip6-hareliability-05.txt
	Pages           : 47
	Date            : 2009-07-13

The home agent can be a single point of failure when Mobile IPv6 is
operated in a system.  It is critical to provide home agent
reliability in the event of a home agent crashing or becoming
unavailable.  This would allow another home agent to take over and
continue providing service to the mobile nodes.  This document
describes the problem scope briefly and provides a mechanism of home
agent failure detection, home agent state transfer, and home agent
switching for home agent redundancy and reliability.

[MEXT] Revised I-D: Problems with the use of IPsec as the security protocol for Mobile IPv6


FYI,

A new version of I-D, draft-patil-mext-mip6issueswithipsec-01.txt has been
successfuly submitted by Basavaraj Patil and posted to the IETF repository.

Filename:        draft-patil-mext-mip6issueswithipsec
Revision:        01
Title:           Problems with the use of IPsec as the security protocol for
Mobile IPv6
Creation_date:   2009-07-13
WG ID:           Independent Submission
Number_of_pages: 15

Abstract:
Mobile IPv6 as specified in RFC3775 relies on IPsec for security.  An
IPsec SA between the mobile node and the home agent provides security
for the mobility signaling.  Use of IPsec for securing the data
traffic between the mobile node and home agent is optional.  This
document analyses the implications of the design decision to mandate
IPsec as the default security protocol for Mobile IPv6 and
consequently Dual-stack Mobile IPv6 and recommends revisiting this
decision in view of the experience gained from implementation and
adoption in other standards bodies.
