Network Function Virtualization (NFV) has been used in the past years for efficient deployment of 4G and 5G network functions (NF) on the cloud. However, private industrial mobile networks have different requirements in terms of latency and connectivity. These requirements impact mainly the user plane. Thus, network functions handling the signaling can reside on the cloud but a new solution is required for managing the user plane on-premises to reduce latency and improve reliability. In this talk, we describe a novel design of the User Plane Function (UPF) based on eBPF framework available in Linux OS. Initial implementation and performance results of the eBPF based UPF will be shared during session.
