Hi all, 

A new revision (-03) of draft-dong-spring-sr-for-enhanced-vpn has been submitted. 

The major change is that it describes options for identifying the topology and associated resource information of each virtual network in SR data plane, both SR-MPLS and SRv6 are considered. The potential benefit is to optimize the scalability when several virtual networks share the same topology but map to different set of network resources. 

We'd like to hear feedbacks from you on whether such options should be included in this draft, and if so which option is preferred for SR-MPLS and SRv6 respectively. Then we will give more details about the preferred option in next revision.

Comment is always welcome. Thanks.

Best regards,
Jie

> Abstract:
>    Enhanced VPN (VPN+) is an enhancement to VPN technology to enable it
>    to support the needs of new applications, particularly applications
>    that are associated with 5G services.  These applications require
>    better isolation from both control and data plane's perspective and
>    have more stringent performance requirements than can be provided
>    with overlay VPNs.  The characteristics of an enhanced VPN as
>    perceived by its tenant needs to be comparable to those of a
>    dedicated private network.  This requires tight integration between
>    the overlay VPN and the underlay network resources in a scalable
>    manner.  An enhanced VPN may form the underpinning of 5G network
>    slicing, but will also be of use in its own right.  This document
>    describes the use of segment routing based mechanisms to provide the
>    enhanced VPN service with dedicated network resources.  The proposed
>    mechanism is applicable to both SR with MPLS data plane and SR with
>    IPv6 data plane (SRv6).
