Realization\r\nof 5G slicing implies requirements for all mobile domains, including\r\nthe Radio Access Network (RAN), Core Network (CN), and Transport\r\nNetwork (TN).\r\n\r\nThis document describes a network slice realization model for IP\/MPLS\r\nnetworks with a focus on the Transport Network fulfilling the service\r\nobjectives for 5G slicing connectivity. The realization model reuses\r\nmany building blocks commonly used in service provider networks at\r\nthe current time.","pub_date":"November 2025","keywords":["L3VPN","L2VPN","Slice Service"],"obsoletes":[],"obsoleted_by":[],"updates":[],"updated_by":[],"see_also":[],"doi":"10.17487\/RFC9889","errata_url":null}
