Dear Chairs and WG, 

We have submitted a new version of draft-dong-6man-enhanced-vpn-vtn-id before the cut-off.

In this version, some background information about VPN+, VTN are provided in the abstract and the introduction section. Some descriptions about the mechanisms used to define the VTN logical topology (e.g. MT, Flex-Algo) are briefly introduced.

With this update, the authors believe all the comments received after IETF 111 (both online and offline) have been solved, and this version is ready for WG adoption. 

Thus we would like to request the WG chairs to initiate the adoption poll on this version, many thanks.

Best regards,
Jie (on behalf of the coauthors)

Abstract:
   Virtual Private Networks (VPNs) provide different customers with
   logically separated connectivity over a common network
   infrastructure.  With the introduction and evolvement of 5G and other
   network scenarios, some existing or new customers may require
   connectivity services with advanced characteristics comparing to
   traditional VPNs.  Such kind of network service is called enhanced
   VPNs (VPN+).

   A Virtual Transport Network (VTN) is a virtual underlay network which
   consists of a set of dedicated or shared network resources allocated
   from the physical underlay network, and is associated with a
   customized logical network topology.  VPN+ services can be delivered
   by mapping one or a group of overlay VPNs to the appropriate VTNs as
   the virtual underlay.  In packet forwarding, some fields in the data
   packet needs to be used to identify the VTN the packet belongs to, so
   that the VTN-specific processing can be performed on each node the
   packet traverses.

   This document proposes a new Hop-by-Hop option of IPv6 extension
   header to carry the VTN Resource ID, which is used to identify the
   set of network resources allocated to a VTN for packet processing.
   The procedure for processing the VTN option is also specified.
