Towards a P4-programmable high-performance 5G Access Gateway Function (AGF)

Next generation (5G) mobile networks address diverging requirements from different industry segments by sharing and isolating resources over the same physical infrastructure. This paradigm led to the objective of Fixed Mobile Convergence (FMC), an attempt to integrate fixed-line access to the 5G core system. The Access Gateway Function (AGF) is presently being considered as a mean to achieve FMC. To fulfill the quality of service (QoS) requirements of the different network slices, it is crucial for the AGF to rely on programmable data planes that are aware of QoS and that can be configured to enforce it. The P4 language allows one to effectively describe the pipeline behavior of network devices by combining the flexibility of software and the high-performance of hardware. This project proposes to evaluate the feasibility of a P4-programmable 5G AGF using a heterogenous hardware platform that combines the capabilities of a commercially available device such as the Tofino with reconfigurable field programmable gate arrays (FPGAs), with the aim to achieve high throughput, programmability and reconfigurability, while enforcing QoS.
