Network slicing is a feature that was introduced by the 3rd
Generation Partnership Project (3GPP) in Mobile Networks. Realization
of 5G slicing implies requirements for all mobile domains, including
the Radio Access Network (RAN), Core Network (CN), and Transport
Network (TN).

This document describes a network slice realization model for IP/MPLS
networks with a focus on the Transport Network fulfilling the service
objectives for 5G slicing connectivity. The realization model reuses
many building blocks commonly used in service provider networks at
the current time.

This document is a product of the Traffic Engineering Architecture and Signaling Working Group of the IETF.
