Feature Description
In the Private 5G networks, where the uplink traffic is more than the downlink traffic, the number of gNodeBs are limited. UPF achieves the optimal distribution of subscriber traffic using the Receive Side Scaling (RSS) concept. However, due to limited number of VPP worker threads on UPF, the ingress traffic does not get evenly distributed across them. It limits the UPF from optimally utilizing all the worker threads, and therefore impacts the subscriber’s uplink throughput.
UPF allows utilizing the VPP worker threads in an optimal manner by creating the unique GTPU 3-tuple hash entries on the UPF’s forwarding plane. It ensures an optimum distribution of ingress traffic on the N3 interface. It enables UPF to perform traffic processing to its maximum capacity ensuring high uplink throughput for Private 5G networks.
