About this guide

This document provides an overview of the Nokia control and user plane separation (CUPS) solution. The Nokia Multi-Access Gateway - controller (MAG-c) functions as the control plane (CP) and has the ability to control SR OS-based user planes (UPs). The various UP functions include the broadband network gateway (BNG), the combined service gateway/packet data gateway (SGWSGW-U/PGWPGW-U), and the 5G user plane function (UPF).

Note: This guide covers content for the release specified on the title page of the guide, and may also contain content to be released in later maintenance loads. See the applicable MAG-c Release Notes for information about features supported in each load of the release software.
Note: The information in this guide is intended to be used in conjunction with the 7750 SR software user guides. The 7750 SR software user guides describe SR OS service features that are supported by the MAG-c. For specific guide titles, see the 7450 ESS, 7750 SR, 7950 XRS, and VSR Documentation Suite Overview Card 20.10.R1.
