    abstract =  {Future networks that support advanced services, such as those enabled by 5G mobile networks, envision a set of overlay networks each with different performance and scaling properties. These overlays are known as network slices and are realized over a common underlay network. In the context of IETF technologies, they are known as IETF network slices. In order to support IETF network slicing, as well as to offer enhanced VPN services in general, it is necessary to define a mechanism by which specific resources (links and/or nodes) of an underlay network can be used by a specific network slice, VPN, or set of VPNs. This document sets out such a mechanism for use in Segment Routing networks.},
