Re: [netext] New version of virtual interface draft(draft-trung-netext-virtual-interface-01)

["Yuri Ismailov" <yuri.ismailov at ericsson.com>]

Hi Trun,
Read the draft, intresting piece of work.

Was a bit puzzled about the following paragraph:

"The mobile access gateway should include the flow information in the
Proxy Binding Update sent to the local mobility anchor.  To get the
flow information, the mobile access gateway can collect information
about the service identifier at layer 2 when a mobile node attach to
it.  We can refer to the draft [9] for more detail about the service
identifier."

Here are my questions
1. What is service identifier? I did not find any mentioning about it in the referenced draft [9]
2. How does that relates to layer 2? Is that access specific?
3. Exchage of information about routing flows to a particular interface in draft [9] is performed between MN and HA at layer 3.
Do you mean that MN should send this info to MAG at layer 3?

Regards
Yuri

Hi all,

We have updated new version of virtual interface draft at http://www.ietf.org/id/draft-trung-netext-virtual-interface-01.txt

There have been several documents mentioning about virtual interface solution, but few of them discuss detail about how to change the
PMIPv6 operations to support virtual interface.

In this Internet draft we suggest the necessary changes in PMIPv6 operations to support virtual interface.  This is just a primary version. We would like to improve it as an official document for
PMIPv6 to support virtual interface.

Your comments are always appreciated and welcomed.

Regards,
TrungTM

A new version of I-D, draft-trung-netext-virtual-interface-01.txt has been successfuly submitted by Tran Trung and posted to the IETF repository.

Filename:        draft-trung-netext-virtual-interface
Revision:        01
Title:           Virtual interface for supporting multihoming and inter technology handover
Creation_date:   2009-10-27
WG ID:           Independent Submission
Number_of_pages: 9

Abstract:
The Proxy Mobile IPv6 supports a mobile node to perform inter- technology handover as well as multihoming.  However the inter- technology handover requires the new interface to use the same network prefix with the old one and all the IP address/prefix at the old interface are removed.  These requirements disable multihoming function which requires different network prefixes for different interfaces.  In this Internet draft we address this problem and suggest the necessary changes in PMIPv6 operations to support a mobile node to perform multihoming as well as seamless inter technology handover with virtual interface.
