Re: [Teas] I-D Action: draft-ietf-teas-enhanced-vpn-03.txt

Hi all,

A new revision of draft-ietf-teas-enhanced-vpn has been submitted. Here are the changes:

1. Add descriptions about 5G network slicing and its relationship with transport network and enhanced VPN.

2. Refine the definition of transport network slicing. 

3. Clarify the role of the existing service data models in enhanced VPN management and 5G end-to-end network slicing.

4. Trim the text about segment routing.

5. Add sections about SDN scaling and Telemetry.

6. Add some text to the security considerations. 

7. Editorial changes according to the comments received both online and offline.

As always, review and comments are appreciated.

Best regards,
Jie

> Abstract:
>    This document specifies a framework for using existing, modified and
>    potential new networking technologies as components to provide an
>    Enhanced Virtual Private Network (VPN+) service.  The purpose is to
>    support the needs of new applications, particularly applications that
>    are associated with 5G services, by utilizing an approach that is
>    based on existing VPN and TE technologies and adds features that
>    specific services require over and above traditional VPNs.

>    Typically, VPN+ will be used to form the underpinning of network
>    slicing, but could also be of use in its own right.  It is not
>    envisaged that large numbers of VPN+ instances will be deployed in a
>    network and, in particular, it is not intended that all VPNs
>    supported by a network will use VPN+ techniques.
