Methodology¶
Tests were performed using iperf3 to measure the throughput between the
UE and an iPerf3 server going through the UPF.
The tests results were obtained by running each test 5 times and averaging the results.
Environment¶
UPF Host¶
Hardware:
CPU: Intel i5-1240P
RAM: 32 GB DDR5
Network cards: Intel 82599ES 10-Gigabit SFI/SFP+
Software:
OS: Ubuntu 24.04
Kubernetes: microk8s 1.31.3
sdcore-upf-k8s: 1.5/stable; revision 691
RAN Host¶
Hardware:
CPU: Intel i5-1240P
RAM: 16 GB DDR5
Network cards: Intel 82599ES 10-Gigabit SFI/SFP+
Software:
OS: Ubuntu 24.04
Kubernetes: microk8s 1.31.3
UERANSIM simulator¶
The UPF performance was tested with the ueransim simulator on the RAN host.
The version used for this test was:
ueransim snap: latest/edge, revision 3, version 3.2.6+git
This test is limited by the simulation done by ueransim and the CPU.
Over the air with OpenAirInterface¶
The throughput was tested end-to-end with Charmed OAI RAN running on the RAN host with a bandwidth of 40 MHz. The radio unit used was a USRP B210 and the UE module was a Quectel RM520N-GL over USB.
This test is limited by the radio link configuration.
