Hi Sri,
Thank you for your reply and clarifications.
I think Kalyani's work is extremely valuable, but we also need to set an 
strategy for our reply back to 3GPP. Currently most discussions are about 
individual protocols such as SRV6, LISP/ILSP, ILNP, ILA, etc. which are really 
in one form or another a type of ID-Location approach.  I believe we first need 
to address 3GPP's request from the architecture point of view, before we dive 
into implementation details. Is there any discussion around different competing 
network architectures?

Not sure if you have seen a white paper titled "Evolving 5G Routing" by Docomo, 
Huawei and others. We also hosted a live webcast demo that shows two LTE slices 
using ID-Location for data path and distribute ID-Location information to 
interested eNodeBs via public cloud pub/sub service. The result is very 
promising and shows the capability of this architecture.

I believe the combination of the white paper and the demo could perhaps serve 
as a good starting point to get the architecture discussion going and that's 
where conference calls can come handy. I agree though let's start with the 
mailing list and move to calls next.

Best regards,

Re: [DMM] FW: New Liaison Statement, "LS on indicating service continuity usage of the additional IPv6 prefix in Router Advertisement"

[Alexandre Petrescu]

Yes,
and we should also encourage them to talk in terms of prefixes also, not 
only in terms of addresses.


Whenever 3GPP says "SSC mode 1 ... IP address is preserved" it should 
say "IP address or IP prefix is preserved".


Because there are places where the 3GPP network gives a /56 prefix to UE 
using DHCPv6-PD.  That's clearly not one address.


This is a question I made to the operator giving DHCPv6-PD: is the 
allocated /56 resisting handovers (stays same upon handovers)?  I am 
told the /56 resists to handovers, to a certain extent.

Purpose: For information

Body: 1. Overall Description:
3GPP working group SA2 (System Architecture) would like to inform the
IETF that SA2 has defined three SSC (Session and Service Continuity)
modes in 3GPP TS 23.501 ("Architecture for the 5G System") clause 5.6.9
as follows:
- With SSC mode 1, the network preserves the connectivity service
provided to the UE. For the case of PDU Session of IPv4 or IPv6 type, the
IP address is preserved.
- With SSC mode 2, the network may release the connectivity service
delivered to the UE and release the corresponding PDU Session. For the
case of IPv4 or IPv6 type, the network may release IP address(es) that
had been allocated to the UE.
- With SSC mode 3, changes to the user plane can be visible to the UE,
while the network ensures that the UE suffers no loss of connectivity. A
connection through new PDU Session Anchor point is established before the
previous connection is terminated in order to allow for better service
continuity. For the case of IPv4 or IPv6 type, the IP address is not
preserved in this mode when the PDU Session Anchor changes.
SA2 has also adopted the use of IPv6 multi-homing in a PDU Session
(referred to as "multi-homed IPv6 PDU Session") as described in 3GPP TS
23.501 clause 5.6.4.3, a PDU Session being an association between the UE
and a Data Network that provides a data connectivity service, which is
also defined in 3GPP TS 23.501.
When a new IPv6 Prefix is assigned to the UE for a multi-homed IPv6 PDU
Session, SA2 has decided to use the Router Advertisement message
according to IETF RFC 4191 to deliver the new IPv6 prefix to the UE and
configure the Routing Rules in the UE by using the Route Information
Option.
SA2 is looking for a mechanism to deliver information regarding the
service continuity usage (e.g. whether the prefix can be replaced with or
without grace period) associated with the new IPv6 prefix to the UE via
the 5G System user plane.

SA2 understands that the IETF draft "draft-ietf-dmm-ondemand-mobility-12"
defines four IP address types that can be mapped to the three SSC modes
as follows:

- SSC mode 1 corresponds to either FIXED or SESSION_LASTING;
- SSC mode 2 corresponds to NON_PERSISTENT;
- SSC mode 3 corresponds to GRACEFUL_REPLACEMENT.

SA2 would like to understand if there is any IETF work related to
delivery of the IP address type (according to IETF draft
"draft-ietf-dmm-ondemand-mobility-12") in the Router Advertisement
message, which could be used for delivery of the service continuity usage
associated with a new IPv6 prefix in a multi-homed IPv6 PDU Session.

Hi Sri,
Thank you for your reply and clarifications.
I think Kalyani’s work is extremely valuable, but we also need to set an 
strategy for our reply back to 3GPP. Currently most discussions are about 
individual protocols such as SRV6, LISP/ILSP, ILNP, ILA, etc. which are really 
in one form or another a type of ID-Location approach.  I believe we first need 
to address 3GPP’s request from the architecture point of view, before we dive 
into implementation details. Is there any discussion around different competing 
network architectures?

Not sure if you have seen a white paper titled “Evolving 5G Routing” by Docomo, 
Huawei and others. We also hosted a live webcast demo that shows two LTE slices 
using ID-Location for data path and distribute ID-Location information to 
interested eNodeBs via public cloud pub/sub service. The result is very 
promising and shows the capability of this architecture.

I believe the combination of the white paper and the demo could perhaps serve 
as a good starting point to get the architecture discussion going and that’s 
where conference calls can come handy. I agree though let’s start with the 
mailing list and move to calls next.

Hi Sri,
Thank you for your reply and clarifications.
I think Kalyani's work is extremely valuable, but we also need to set an 
strategy for our reply back to 3GPP. Currently most discussions are about 
individual protocols such as SRV6, LISP/ILSP, ILNP, ILA, etc. which are really 
in one form or another a type of ID-Location approach.  I believe we first need 
to address 3GPP's request from the architecture point of view, before we dive 
into implementation details. Is there any discussion around different competing 
network architectures?

Not sure if you have seen a white paper titled "Evolving 5G Routing" by Docomo, 
Huawei and others. We also hosted a live webcast demo that shows two LTE slices 
using ID-Location for data path and distribute ID-Location information to 
interested eNodeBs via public cloud pub/sub service. The result is very 
promising and shows the capability of this architecture.

I believe the combination of the white paper and the demo could perhaps serve 
as a good starting point to get the architecture discussion going and that's 
where conference calls can come handy. I agree though let's start with the 
mailing list and move to calls next.

Best regards,
Arashmid Akhavain

Arashmid  - We do have regular DMM working group meeting during the IETF week. 
I guess, what you are asking for is a WG-chair scheduled conference calls? DMM 
List may be very quite, but there have been regular conf calls between authors 
of some of the WG documents. Authors of FPC host those calls regularly. For the 
new work item that Kalyani is proposing, we need to have some discussions in 
the mailer and once the document is adopted as a WG document, we can certainly 
host some calls (author/chair scheduled) on a need basis. So, the first step is 
to post comments on the documents and trigger some discussions.


Sri

Hi everyone,
Online meetings on a regular basis can perhaps help moving things forward.

Folks:

Here is the draft with 3GPP architecture described as much as relevant to N9 
interface.
I have extracted some diagrams from 3GPP specs and will redo them in ASCII 
after I get
some feedback on whether to include them or not in this document.

Folks:

In response to the 3GPP CT4 study item on user plane protocols, we propose that 
a white paper
be developed that can compare the different IETF protocols. Attached is an 
outline. Please let me
know if you would like to contribute.

[DMM] I-D Action: draft-ietf-dmm-ondemand-mobility-13.txt

[internet-drafts]

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Distributed Mobility Management WG of the IETF.

Title   : On Demand Mobility Management
Authors : Alper Yegin
  Danny Moses
  Kisuk Kweon

  Jungshin Park
  Seil Jeon
Filename: draft-ietf-dmm-ondemand-mobility-13.txt
Pages   : 16

Abstract:
   Applications differ with respect to whether they need IP session
   continuity and/or IP address reachability.  The network providing the
   same type of service to any mobile host and any application running
   on the host yields inefficiencies.  This document describes a
   solution for taking the application needs into account by selectively
   providing IP session continuity and IP address reachability on a per-
   socket basis.
