  - Introduction to PFCP and CUPS concepts
    The interfaces between the MAG-c and the BNG-UP that are related to PFCP are the SCi, CPRi, Sx, N4, Sx-u, and N4-u interfaces. Get a brief overview of those interfaces and of general CUPS and BNG concepts, including PFCP association and path, PFCP session, and PDR.
  - Forwarding between MAG-c and BNG-UP
    The forwarding of control plane messages is in-band and sent using an IBCP tunnel.
  - Session handling
    A PFCP session is set up to control the creation, modification, and deletion of a bundle of PDRs. There is a single PFCP session per connected device.
  - PFCP protocol
    The core of session management is the PFCP protocol as defined in 3GPP TS 29.244, with BNG-specific extensions defined in BBF TR-459.
