FortiGate-7000E and 7000F PFCP support

FortiOS Carrier 7.0.5 for FortiGate-7000E and 7000F includes support for load balancing the Packet Forwarding Control Protocol (PFCP). PFCP is a new addition to 3GPP that provides 4G Control plane and User Plane Separation (CUPS) and 5G signaling evolution. When PFCP is used as the control plane, the user plane is GTPv1-U. PFCP takes many of the roles that are provided by GTP-C in 3G/4G networks today and provides session awareness and tracking of GTPv1-U user plane traffic while also providing control plane initiation.

PFCP support includes supporting PFCP session synchronization for FGCP HA.

PFCP support also includes a new default flow rule. This flow rule is disabled by default. When enabled, this flow rule sends all PFCP traffic to the primary FPM.
