Control Plane Function Guide
This guide describes the control plane function (CPF) for control and user plane separation (CUPS) solutions. The CPF is based on the packet forwarding control protocol (PFCP) interface as defined in 3GPP TS 29.244 for mobile 4G CUPS and 5G.

  - Getting started
    Find general information about this guide.
  - Session management
    Get a general overview of the session functionality and the address assignment protocols, and details on the IPoE and PPPoE fixed access and the fixed wireless access (FWA) session types.
  - Address assignment
    Overview of the address assignment, and details on the supported local (ODSA) and AAA-based address assignment.
  - Authentication
    Configure authentication for a new MAG-c session, including the RADIUS authentication profile. Learn about the BNG EP and ADB lookup process.
  - Accounting and charging
    Learn about the statistics collection from the BNG-UP, time-based and volume-based charging, RADIUS accounting configuration, and buffering of the RADIUS accounting messages for later retransmission.
  - Residential NAT
    Get an explanation of NAT on BNG CUPS, learn about the functional split between MAG-c and BNG-UP, NAT configuration, logging, and operational commands.
  - Geo-redundancy
    Two MAG-c systems can be deployed in a geo-redundant configuration. If one system fails, the other system ensures uninterrupted service and minimizes the impact of failure for broadband clients.
  - Python support
    A user-defined Python script can customize the MAG-c behavior.
  - BNG-UP resiliency
    An overview of the BNG-UP resiliency function and capabilities, resiliency handling, and deployment use cases.
