RFC 9889: A Realization of Network Slices for 5G Networks Using Current IP/MPLS Technologies

In plain English — editorial summary, not part of the RFC

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.
