Simple Measurement of UPF Performance 4

This describes simple performance measurements of several open source UPFs by using PacketRusher as the performance measurement tool. For this measurement, VMs in the measurement environment was changed from Virtualbox used in previous measurement to Proxmox VE. For other measurement results, please see Performance Measurement. PacketRusher is also featured on HPE Developer Blog.

Note. Performance measurement results are highly dependent on the measurement conditions. These results are only examples of results under certain measurement conditions. And this is a very simple measurement, and according to this comment, it doesn't seem to make much sense to measure between VMs. I hope it will serve as a reference for a simple configuration when measuring on real devices.

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 Proxmox VE 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 v2.7.2 (2024.10.11) - https://github.com/open5gs/open5gs
for Open5GS UPF, UPG-VPP and eUPF
5GC - free5GC v3.4.3 (2024.10.11) - https://github.com/free5gc/free5gc
for free5GC UPF (go-upf)
RAN&UE - PacketRusher 20240521 (2024.06.24) - https://github.com/HewlettPackard/PacketRusher
(RAN) - gtp5g v0.9.2 (2024.10.11) - https://github.com/free5gc/gtp5g

The UPFs used are as follows.

Open5GS v2.7.2 (2024.10.11) - https://github.com/open5gs/open5gs
UPG-VPP v1.13.0 (2024.03.25) - https://github.com/travelping/upg-vpp

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.

Build Open5GS, free5GC, UPFs and PacketRusher

Please refer to the following for building Open5GS, free5GC, UPFs and PacketRusher respectively.

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

In gtp5g v0.8.7 and later, GTP-U Sequence Number is enabled by default. In this case, eUPF will probably not be able to process GTP-U packets correctly due to a bug in gtp5g. Therefore, if connecting to eUPF, please disable GTP-U Sequence Number of gtp5g used by PacketRusher as follows.

# echo 0 > /proc/gtp5g/seq

This measurement will be performed with the GTP-U Sequence Number disabled.

Additional Information. This has fixed the bug in gtp5g.

Establish a connection for one UE.

INFO[0002] [UE][GTP] sudo ip vrf exec vrf0000001000 iperf3 -c IPERF_SERVER -p PORT -t 9000

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.

Run iPerf3 server on Data Network Gateway (VM-DN)

# iperf3 -s

Try ping and iPerf3 client on VM2

Try ping and iperf3 client to the address(192.168.16.152) of N6 interface on Data Network Gateway.

e.g.) The UPF used in the measurement below is UPG-VPP v1.13.0.

Results

These measurements are the values measured between the IP address 10.45.0.0/16 assigned by PacketRusher on VM2 and the IP address 192.168.16.152 of the Data Network Gateway N6 interface on VM-DN. The measurements were taken in the following pattern:

iperf3 -c 192.168.16.152
iperf3 -c 192.168.16.152 -u -b 5G
UDP packet loss is a value measured under deliberate load (5 Gbps) 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 native. Note that generic mode is implemented at the kernel level, so it does not contribute to performance improvement. If it is set to offload(NIC-level implementation), it may be expected to more improved performance than native (Driver-level implementation). For reference, a list of drivers that support XDP can be found here.

Summary

These measurement results show that UPG-VPP has relatively outstanding performance even on Proxmox VE VM. If measuring using virtual machines, it would be better to measure on VMs on a hypervisor such as Proxmox VE. Also, it is good to select VirtIO as the network interface to ensure that the network does not become a bottleneck in the measurement.

It is very simple mesurement and may not be very meaningful when measuring between virtual machines, 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.

Performance of N6 interface only

I simply measured the raw communication performance between VM-UP and VM-DN. This is a measurement of the N6 interface and therefore does not include communication over GTP-U.

A--B	1) TCP throughput	2) UDP throughput	2) UDP packet loss	3) RTT (msec)
VM-UP --(N6)-- VM-DN	S:25.6 Gbps R:25.5 Gbps	S:2.99 Gbps R:2.83 Gbps	6.9 %	0.260
