Scope
FlexRAN is a vRAN reference implementation for virtualized cloud-enabled radio access networks. FlexRAN is not an open-source project. It is provided here as an example of a 5G application running on INF.
This document provides details on how to build FlexRAN software for INF, generate a containerized version of the prebuilt FlexRAN binaries, and deploy on INF solution.
Note:
The steps in this guide are based on FlexRAN 22.03. The instructions are subject to change in future releases of FlexRAN.
And only CentOS based INF image is verified.
Intended Audience
The intended audience for this document are software engineers and system architects who want to design and develop 5G systems using the O-RAN Specifications based on FlexRAN and INF platform.
INF AIO Simplex Installation
S1 Prepare USB stick with INF CentOS based Installation ISO
S1.1 Get INF CentOS based Installation ISO from following location:
S1.2 - Burn the image to a USB stick:
Be sure to use the correct USB device name when copying the image.
dd if=inf-image-centos-all-x86-64.iso of=/dev/sdc bs=1M
S2 Follow the installation guide
In addition to the Hardware Requirements for INF (INF is a downstream project of StarlingX, and the requirements are the same as StarlingX), you will need the following hardware for FlexRAN applications.
Minimum Requirement | All-in-one Controller Node |
---|---|
Minimum processor class | Single-CPU Intel Xeon Cascade Lake (14 nm) or IceLake (10 nm) |
Minimum memory | 64 GB single socket |
Minimum network ports | OAM: 1x1GE, If only test timer mode, no other NIC required. |
BIOS settings |
|
Accelerator Card | Mt. Bryce ACC100 (Intel eASIC chip which can be mounted on third party card) |
The FlexRAN application on INF has been tested on Intel Reference Hardware platform: Coyote Pass (housing ICX-SP).
Note
Some third-party platforms like SuperMicro / HPE / Dell / Quanta / and others can also be used depending on customer platform requirements, certain optimizations for low-latency and power savings mode by the platform vendors.
S2.1 Please follow this installation guide:
- Install Kubernetes Platform on All-in-one Simplex:
- When install controller-0 from the image, please select ‘All-in-one (lowlatency) Controller Configuration’
S2.2 In addition to required StarlingX configuration, you must set up the Ceph backend for Kubernetes PVC, isolcpus and hugepages:
source /etc/platform/openrc NODE=controller-0 OAM_IF=<OAM-PORT> # if you use flat oam network system host-if-modify ${NODE} $OAM_IF -c platform system interface-network-assign ${NODE} $OAM_IF oam # if you use vlan oam network VLANID=<VLAN-ID> system host-if-modify -n pltif -c platform $NODE $OAM_IF system host-if-add ${NODE} -V $VLANID -c platform oam0 vlan pltif system interface-network-assign ${NODE} oam0 oam system host-label-assign $NODE sriovdp=enabled system host-label-assign $NODE kube-topology-mgr-policy=restricted # Ceph backend for k8s pvc system storage-backend-add ceph --confirmed system host-disk-list ${NODE} | awk '/\/dev\/sdb/{print $2}' | xargs -i system host-stor-add ${NODE} {} # isolate cpus depends on number of the physical core system host-cpu-modify -f application-isolated -p0 28 $NODE # allocate/enable hugepages for DPDK usage system host-memory-modify $NODE -1G 10 0 system host-unlock $NODE
S2.3 After the system has been unlocked and available for the first time, configure ACC100 / Mount Bryce:
source /etc/platform/openrc NODE=controller-0 system host-lock $NODE # get the device name of the Mount Bryce, we assume it is # pci_0000_8a_00_0 here. system host-device-list $NODE # Modify the Mount Bryce device to enable it, specify the base driver # and vf driver, and configure it for 1 VFs # NOTE: If this is the initial install and have not unlocked, you will # get following error message. # Cannot configure device 73b13ddf-99be-44c8-8fbe-db85eb8d99ba until host # controller-0 is unlocked for the first time. system host-device-modify $NODE pci_0000_8a_00_0 -e true --driver igb_uio --vf-driver vfio -N 1 system host-unlock $NODE

Build, Deploy and Run FlexRAN
Generally speaking, the build and execution environments should not be the same. To facilitate building, deploying, and running the process on INF, a custom containerized build environment has been prepared and verified. Developers can use the instructions to build the customized Docker image themselves or use the prebuilt Docker image directly.
Using this method, developers can:
Start the build soon after INF is ready.
Use the scripts provided to generate a Docker image with pre-built FlexRAN binaries.
Launch the FlexRAN Pod using the image just generated.
Execute L1 test cases.
The following procedures provide detailed instructions for completing the stages described above.
S3 FlexRAN build preparation
For details, see:
https://www.intel.com/content/www/us/en/developer/topic-technology/edge-5g/tools/flexran.html
You can find build instructions in the Compilation Chapter of FlexRAN 5GNR Reference Solution 22.03.
The following steps provide a quick-start procedure for developers.
S3.1 Create a PVC for FlexRAN build storage:
Note: ThePVCsize should be larger than 70G.

S3.3 Launch the building pod attaching to the PVC:
Note: This pod is assumed to be assigned enough resources to launch quickly after FlexRAN is built. If you don’t have isolated CPU, hugepage and accelerator resources configured as part of the system used for building, feel free to remove related content from the yaml spec file. Hugepages-1Gi and intel.com/intel_acc100_fec are not required to perform the build.

S4 Build FlexRAN in Pod
S4.1 Use a shell inside Pod to build FlexRAN:
kubectl exec -it buildpod -- bash
S4.2 Usescp
to copy the FlexRAN related files into the pod’s PVC:
mkdir -p /opt/fb/scratch && cd /opt/fb/scratch scp <options> FlexRAN-22.03-L1.tar.gz_part00 . scp <options> FlexRAN-22.03-L1.tar.gz_part01 . scp <options> dpdk_patch-22.03.patch . cat FlexRAN-22.03-L1.tar.gz_part00 FlexRAN-22.03-L1.tar.gz_part01 > FlexRAN-22.03-L1.tar.gz rm FlexRAN-22.03-L1.tar.gz_part00 rm FlexRAN-22.03-L1.tar.gz_part01
S4.3 Copy DPDK source code into the pod’s PVC
cd /opt && wget http://static.dpdk.org/rel/dpdk-21.11.tar.xz tar xf dpdk-21.11.tar.xz mv dpdk-21.11/ /opt/fb/dpdk-flxr-22.03 cd /opt/fb/dpdk-flxr-22.03 patch -p1 < /opt/fb/scratch/dpdk_patch-22.03.patch
S4.4 Install oneAPI (ICX) Compiler
cd /opt/fb/scratch/ wget https://registrationcenter-download.intel.com/akdlm/irc_nas/18487/l_BaseKit_p_2022.1.2.146_offline.sh chmod a+x l_BaseKit_p_2022.1.2.146_offline.sh ./l_BaseKit_p_2022.1.2.146_offline.sh -a -s --eula accept --install-dir /opt/fb/intel/oneapi
S4.5 Extract FlexRAN and populate the environment variables
cd /opt/fb/scratch/ && tar zxvf FlexRAN-22.03-L1.tar.gz && ./extract.sh # input '/opt/fb/flexran' for Extract destination directory cd /opt/fb/flexran/ TARGET_COMPILER=icx source ./set_env_var.sh -d # When following promote message shows: # Enter One API Install Directory for icx, or just enter to set default # input: /opt/fb/intel/oneapi # promote message shows: # Enter DPDK Install Directory, or just enter to set default # input: /opt/fb/dpdk-flxr-22.03
S4.6 Switch to devtoolset-8 environment
scl enable devtoolset-8 bash
or
source /opt/rh/devtoolset-8/enable
S4.7 Build FlexRAN SDK
cd /opt/fb/flexran && ./flexran_build.sh -e -r 5gnr -m sdk
S4.8 Build DPDK with the FlexRAN patch
cd /opt/fb/dpdk-flxr-22.03 && meson build cd /opt/fb/dpdk-flxr-22.03/build && meson configure pip3 install pyelftools work_path=/opt/fb/flexran/sdk/build-avx512-icx/install && ninja
S4.9 Build the FlexRAN applications
cd /opt/fb/flexran # compile all available modules for 5gnr ./flexran_build.sh -e -r 5gnr
S5 Generate Docker image with FlexRAN binaries
Note: Since host path/var/run/docker.sock
has been mounted into the building pod, you can build the Docker image using the FlexRAN binaries from the previous step inside the building pod. The artifacts used by docker build have been integrated into the build image and are ready to use.
S5.1 Prepare the env var for the script in /root/docker-image-building/transport.sh
:
source /opt/fb/intel/oneapi/setvars.sh cd /opt/fb/flexran && source ./set_env_var.sh -d
S5.2 Prepare binaries and scripts for Docker build:
cd /root/docker-image-building ./transport.sh
S5.3 Build Docker image which will be saved in local host:
docker build -t flr-run -f Dockerfile .
S6 Run the FlexRAN Test cases in Pod
After the build and Docker image generation steps above, you can launch the FlexRAN execution pod from the host.
S6.1 Push the Docker image to registry.local:9001
# change to host side, in this case, it should be controller-0 host sudo docker login registry.local:9001 -u admin -p <your_sysadmin_passwd> sudo docker tag flr-run registry.local:9001/flxrun:22.03 sudo docker push registry.local:9001/flxrun:22.03
S6.2 Launch the FlexRAN Pod.
Adjust the CPU and memory for your configuration. Memory should be more than 32Gi for the test case pass rate.
Note: command
should not be used in the spec, otherwise it will overwrite the default container command which does accelerator PCI address filling for L1.
