S6b Interface
This reference point, between a P-GW and a 3GPP AAA server/proxy, is used for mobility-related authentication. It

non-3GPP access) in the event that dynamic PCC is not supported.
Supported protocols:
Transport Layer: TCP, SCTP
Network Layer: IPv4, IPv6
Data Link Layer: ARP
Physical Layer: Ethernet
