This guide describes the Nokia SR OS User Plane Function (UPF) in a Broadband Network Gateway (BNG) Control and User Plane Separation (CUPS) system. The BNG CUPS UPF is based on the fundamentals of the BNG and reuses fundamental QoS and forwarding concepts, while moving the control plane handling to the BNG CUPS Control Plane Function (CPF).
See the 7450 ESS, 7750 SR, and VSR Triple Play Service Delivery Architecture Guide for more information about BNG.
See the CMG BNG CUPS Control Plane Function Guide for an overview of the BNG CUPS solution and the BNG CUPS CPF.
This guide is organized into functional chapters that provide concepts and descriptions of the implementation flow, as well as Command Line Interface (CLI) syntax and command usage.
