| Body |
1. Description As a follow up to the liaison statement [1] that was posted on 2023-10-09, the IETF TEAS WG [2] would like to inform 3GPP about the progress of “A Realization of IETF Network Slices for 5G Networks Using Current IP/MPLS Technologies” [3], an informational document that has completed Working Group Last Call. This document describes a Network Slice realization model for IP/MPLS networks with a focus on the Transport Network fulfilling 5G slicing connectivity service objectives. The realization model reuses many building blocks currently commonly used in service provider networks. In addition to stating that the reader should refer to "TS 23.501: System architecture for the 5G System (5GS)" [4] for a definitive description of 3GPP network architectures, the document also includes an Appendix [5] that provides a brief 5G overview for the reader’s convenience. 2. Actions The TEAS WG would like to request 3GPP to review the document and provide confirmation that the brief 5G overview included in the Appendix is accurate. The TEAS WG would like to request that feedback on this is provided in an LS by the deadline. The TEAS WG also encourages the use of the TEAS WG mailing list [6] for individuals to send comments, raise concerns and seek clarification on the document. 3. Upcoming Meetings IETF 120 20-26 July 2024, Vancouver, Canada IETF 121 2-8 November 2024, Dublin, Ireland 4.
