Hi all, Network slicing is a key feature for 5G to enable diversified services using the same network infrastructure. In order to support end-to-end network slicing, it is necessary to consider how to provide network slicing in mobile transport network. As segment routing is one of the candidate technologies for 5G transport, it is useful to provide a SR based network slicing solution to meet the requirement on different levels of isolation and network customization. This document is a good starting point in this direction, and we appreciate more review and discussion to help moving this work forward. Best regards, Zhu Yongqing

The major changes in this version are: 1. Clarify that each virtual network can have customized network topology and may have dedicated network resources, so that both soft isolation and hard isolation can be covered. 2. Focus on the usage of SR-MPLS SID and SRv6 locator/SID as data plane identifiers of virtual network topology and resource. 3. In section 5 "Procedures", polish the description about the mechanism of creating SR virtual networks, and clarify that enhanced VPNs can be mapped to the same or different SR virtual networks. 4. Section 6 “Benefits of the proposed mechanism” is simplified by focusing on the features of the proposed mechanism. 5. Add new coauthors. Your review and comments are welcome.

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 topology and 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 required network topology and resources. The overall mechanism of using segment routing to provide enhanced VPN service is also described. The proposed mechanism is applicable to both SR with MPLS data plane and SR with IPv6 data plane (SRv6). Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
