Adaptive Access Gateway Function Framework with P4 Accelerated User Plane

In order to facilitate the 5G Wireless and Wireline Convergence (5G-WWC) architecture, the Access Gateway Function (AGF) is defined as an interworking function between the 5G core (5GC) and fixed network residential gateways (FN-RG), utilizing a non-3GPP wireline access network. As a proxy, AGF enables communication between the FN-RG and the 5GC. This paper presents an adaptive architecture integrating different access gateway functional user planes. We have implemented a P4 switch-accelerated access gateway user plane with data stream bandwidth management to verify the functionality and adaptability of the adaptive architecture.
