Simple Overview of UPF Performance Measurements

Using Open5GS for 5GC, I will easily measure the performance of several open source UPFs with PacketRusher. Note that this configuration is implemented with Virtualbox VMs.

The following minimum configuration was set as a condition.

Only one each for C-Plane, U-Plane(UPF) and RAN&UE(performance measurement tool).

The built simulation environment is as follows.

The 5GC / RAN&UE used are as follows.

5GC - Open5GS v2.7.0 (2023.12.04) - https://github.com/open5gs/open5gs
for Open5GS UPF, UPG-VPP and eUPF
5GC - free5GC v3.3.0 (2023.11.03) - https://github.com/free5gc/free5gc
for free5GC UPF
RAN&UE - PacketRusher (2023.12.06) - https://github.com/HewlettPackard/PacketRusher

The UPFs used are as follows.

Open5GS UPF v2.7.0 (2023.12.04) - https://github.com/open5gs/open5gs
UPG-VPP v1.11.0 (2023.12.11) - https://github.com/travelping/upg-vpp
eUPF v0.6.0 (2023.12.05) - https://github.com/edgecomllc/eupf
free5GC UPF v1.2.0 (2023.11.12) - https://github.com/free5gc/go-upf

Each VMs are as follows.

The network interfaces of each VM except VM-UP are as follows.

The network interfaces of each VM-UP(UPFs) are as follows. Note that UPFs from a to c connect to Open5GS CN, but d free5GC UPF does not support FTUP flag in PFCP Association Setup Request/Respose, so it connects to free5GC CN.

PacketRusher (2023.12.06) - https://github.com/HewlettPackard/PacketRusher/wiki

Install MongoDB on Open5GS and free5GC C-Plane machines. MongoDB Compass is a convenient tool to look at the MongoDB database.

Run Open5GS, free5GC and UPFs

First run each UPF, then each 5GC. Each UPF uses the same IP address, so start only the UPF you want to measure.

Run UPFs

a-1. Run Open5GS 5GC UPF (TUN)

Please use the configuration files changed for TUN interface.

# cd open5gs
# ./install/bin/open5gs-upfd

a-2. Run Open5GS 5GC UPF (TAP)

Please use the configuration files changed for TAP interface.

# cd open5gs
# ./install/bin/open5gs-upfd

b. Run UPG-VPP

See this.

c. Run eUPF

See this.

d. Run free5GC 5GC UPF

# cd free5gc
# ./bin/upf

Run 5GC C-Plane

Run Open5GS 5GC C-Plane

./install/bin/open5gs-nrfd &

Run free5GC 5GC C-Plane

Create the following shell script and run it.

#!/usr/bin/env bash

PID_LIST=()

NF_LIST="nrf amf smf udr pcf udm nssf ausf chf"

export GIN_MODE=release

for NF in ${NF_LIST}; do
    ./bin/${NF} &
    PID_LIST+=($!)
    sleep 1
done

function terminate()
{
    sudo kill -SIGTERM ${PID_LIST[${#PID_LIST[@]}-2]} ${PID_LIST[${#PID_LIST[@]}-1]}
    sleep 2
}

trap terminate SIGINT
wait ${PID_LIST}

Measure using PacketRusher

This time, I will measure only one connection by one UE. First, run PacketRusher to establish a connection that will be used to measure performance. Then, start the iperf3 server on the Data Network Gateway.

Run PacketRusher on VM2

Establish a connection for one UE.

To avoid writing ip vrf exec vrf0000001000 command everytime you want to run a command in the context of the UE/VRF, run the command as follows.

# ip vrf exec vrf0000001000 bash

Then all the commands in the new shell will use the tunnel.

UDP packet loss is a value measured under deliberate load (500 Mbps) in order to compare performance limits.
ping 192.168.16.152 -c 10
These are the measured values when xdp_attach_mode is set to generic due to Virtualbox VM. Note that generic mode is implemented at the kernel level, so it does not contribute to performance improvement. If it is set to native(Driver-level implementation) or offload(NIC-level implementation), it may be expected to more improved performance. For reference, a list of drivers that support XDP can be found here.

These measurement results show that UPG-VPP has relatively outstanding performance even on Virtualbox VM.

It is very simple mesurement and may not be very meaningful when measuring between Virtualbox VMs, but it may be a little helpful when comparing the relative performance of UPF. I would appreciate it if you could use this as a reference as a configuration example when measuring with real devices.

I would like to thank all the excellent developers and contributors who created PacketRusher and other great systems and tools.
