This describes a simple configuration of VPP-UPF and Data Network Gateway, focusing on U-Plane. Note that this configuration is implemented with Proxmox VE VMs.
The following minimum configuration was set as a condition.
- One UPF and Data Network Gateway
The built simulation environment is as follows.
The VPP-UPF used is as follows.

The network interfaces of each VM are as follows.
Note. Do not enable(up) any devices that will be under the control of DPDK.
These devices will be enabled and set IP addresses in the init.conf file of VPP-UPF.

When using the kernel built-in vfio-pci module, please down the ens20/ens21/ens22 interfaces in advance.
And, refer to this and set the kernel to IOMMU mode.
Alternatively, it can be used in No-IOMMU mode.
Then, these interfaces are under DPDK control by running vpp without explicit vfio-pci binding.
Create /root/openair-upf directory and put the configuration files there.
/root/openair-upf/startup.conf
unix {
nodaemon
log /tmp/vpp.log
full-coredump
gid vpp
interactive
cli-listen /run/vpp/cli.sock
exec /root/openair-upf/init.conf
}
api-trace {

path /usr/lib/x86_64-linux-gnu/vpp_plugins/
plugin ikev2_plugin.so {disable}
plugin dpdk_plugin.so {enable}
plugin upf_plugin.so {enable}
}
For example, if you prepare four CPU cores and want to assign CPU core (#0) to main-core and three CPU cores (#1-3) to corelist-workers, configure the startup.conf file as follows.
cpu {
main-core 0
corelist-workers 1-3
}
As a result, each of the three CPU cores has a usage rate of 100% (300% in total). When displayed using the top command, it looks like the following.

With the above steps, the VPP-UPF environment with DPDK has been constructed. You will be able to work VPP-UPF with Open5GS and free5GC. I would like to thank the excellent developers and all the contributors of OpenAir CN 5G for UPF, UPG-VPP and DPDK.
- Open5GS 5GC & UERANSIM UE / RAN Sample Configuration - VPP-UPF with DPDK
- free5GC 5GC & UERANSIM UE / RAN Sample Configuration - VPP-UPF with DPDK
For a simple overview of VPP-UPF at the beginning of this article, read OAI-CN5G-UPF-VPP as UPG-VPP.
VM-UP is as follows.
| VM | SW & Role | IP address | OS | CPU (Min) |
Mem (Min) |
HDD (Min) |
|---|---|---|---|---|---|---|
| VM-UP | UPG-VPP U-Plane | 192.168.0.151/24 | Ubuntu 22.04 | 2 | 8GB | 20GB |
This build instruction is based on vpp.spec of UPG-VPP, and vpp.spec and Dockerfile of FPP-VPP.
I simply confirmed the operation of the following versions.

If you want to install the built files as packages without manually copying these, build binary packages as follows.
# make pkg-deb
...
# cd build-root
# ls -l *.deb

If you want to build in debug mode, make as follows.
...
# make build
# cp -r build-root/install-vpp_debug-native/vpp /usr/local/
If you want to install the built files as packages without manually copying these, build binary packages as follows.
# make pkg-deb-debug
If you want to install the VPP packages on a host other than the one on which these were built, first install the following dependent packages.
# apt install libnl-route-3-200
Then install the VPP packages.
# cd build-root
# dpkg -i *.deb
This allows you to operate VPP service using systemctl.
# cd ~
# git clone https://github.com/travelping/upg-vpp.git
# cd upg-vpp
# git checkout refs/tags/v1.13.0
# make version
# mkdir build
# cd build
# cmake -DVPP_HOME=/usr/local/vpp ..
# make
# cp upf_plugin.so /usr/local/vpp/lib/x86_64-linux-gnu/vpp_plugins
Now the UPG-VPP was built in /usr/local/vpp.
Note.
UPG-VPP v1.13.0 does not support PDU Session container.
Therefore, some gNodeBs may not accept GTP traffic from UPG-VPP that does not contain DL PDU SESSION INFORMATION in the PDU Session container.
In that case, there is a way to try the OAI patch by referring to here.
Also, this is a temporary patch for UPG-VPP v1.13.0 based on the OAI patch. QFI is fixed to 1.
I confirmed that it works with the gNodeB of srsRAN_Project.
If you want to install the built upf_plugin.so etc as packages without manually copying these, build binary packages as follows.
# make package
...
# ls -l *.deb
-rw-r--r-- 1 root root 2866388 May 4 23:57 upf-plugin_1.13.0_amd64.deb
-rw-r--r-- 1 root root 38746 May 4 23:57 upf-plugin-dev_1.13.0_amd64.deb
If you want to install the UPG-VPP packages on a host other than the one on which these were built, first install the following dependent packages.
# apt install libhyperscan-dev
Then install the UPG-VPP packages.
# cd build
# dpkg -i *.deb
Then see here for the original files.

The configuration files used when operating VPP service with systemctl are located in the following directory by default.

As a prerequisite, see here for instructions on binding N3, N4 and N6 network interfaces to DPDK compatible driver.
First, create group vpp if it doesn't exist.
# addgroup vpp
Then run UPG-VPP with DPDK.
# /usr/local/vpp/bin/vpp -c /root/openair-upf/startup.conf
