Mobile IPv6 maintenance: HA never deletes a tunnel


There is a bug in an otherwise very good Mobile IPv6 Home Agent 
implementation.  This particular Home Agent never deletes a tunnel 
interface.  As such it does not support MNs which are silent for a 
while; when they come back up the tunnel is still there and cant be 

A forcing de-register (BU lifetime 0) does not delete it either.

This particular platform has a good Mobile IPv4 implementation.

Am I the only one to experience this bug?

Document Action: 'Distributed Mobility Management: Current practices and gap analysis' to Informational RFC (draft-ietf-dmm-best-practices-gap-analysis-09.txt)

The IESG has approved the following document:
- 'Distributed Mobility Management: Current practices and gap analysis'
  (draft-ietf-dmm-best-practices-gap-analysis-09.txt) as Informational

This document is the product of the Distributed Mobility Management
Working Group.

The IESG contact persons are Brian Haberman and Ted Lemon.

Technical Summary

   The present document analyzes deployment practices of existing IP
   Mobility protocols in a distributed mobility management environment.
   The analyzed IP level (i.e., layer 3) mobility protocols include those
   developed by IETF and also those developed by other SDOs that have
   been widely deployed. Due the plurality of different mobility enabling 
   protocol and solutions, the analysis has been intentionally limited to
   IP level (i.e., layer 3) protocol that typically are based on some sort of
   tunneling solution. The document then identifies existing limitations when
   compared to the distributed mobility management requirements defined in
   draft-ietf-dmm-requirements for a distributed mobility management solution.

   On the existing IP mobility enabling architectures (outside mobile VPNs or
   IETF defined IP mobility solutions), the document considers only the 3GPP 
   GPRS/EPS system and service provider Wi-Fi due their dominant positions
   in the market place.

Maintenance of Mobile IPv6


There are a few things that I think are needed for the maintenance of 
protocol Mobile IPv6; most important appear first:

- help with automated portal authentication in WLAN.  Hopping on and
   off from a WiFi hotspot to another, even without moving physically,
   is often obstructed by web portal authentication requiring user
   to type to fill forms; this is not only inconvenient, but in some
   cases it is impossible, like with vehicular networks where the
   driver is forbidden by law to type while behind the wheel.

- bugs in an otherwise reliable Mobile IPv6 implementation of
   a particular equipment manufacturer (HA never deletes a tunnel,
   lifetime: remaining never): should the bugs be corrected or shoudl
   the spec modified to reflect what the implementation actually
   does?  Should protocol workarounds be designed to deal with this

- future of the maintenance of the linux open source Mobile IPv6
   implementation: just for my clarification - is it still ok?  Is there
   some project behind it?  Or is it dying?  Currently the email list
   seems silent, and the latest software releases date back to more than
   one year.

- elimination, or reducing the effect, of the necessity of the 'focal
   point' Home Agent: route optimization for the masses and for moving
   networks as deployed in vehicles.

- Mobile IPv6 and IPv6 NAT Traversal;

- IPv6 NAT in a moving network;

- bypassing Mobile IPv6 implementation (and use IPv6 NATting) in cases
   of particular applications, based on destination IPv6 address and
   IPv6-only-when-reversed FQDN name.

- the use of ULAs combined with Global addresses, with Mobile IPv6
   (e.g. ULA HoA but GUA CoA, or reverse).

What do you think?

Fwd: New Version Notification for draft-perkins-dmm-privacy-00.txt

Hello folks,

We have put together a draft about privacy considerations for DMM.

Privacy is a very timely subject, and I think that it should be a kept in
mind during all design phases for the DMM teams.

This is a simple and short draft to invite discussion.  No doubt there
is a lot of room for expansion of the discussion, and we will be happy
to incorporate other guidelines or references to other relevant IETF
publications that may be suggested.

I have requested a time slot at the upcoming IETF for a discussion
about privacy as it is related to DMM protocol development.

FW: New Version Notification for draft-wei-dmm-address-management-00.txt

Hi all, 
A draft on IP address management in DMM is submitted, I think how IP addresses should be managed in DMM
network is very essential to
source address selection on mobile side, and mobility management signaling on network side, so there
should be a consensus on IP address management issue.

Comments are welcomed! Thanks!
