4gc

The 4gc repository builds a standalone Aether core with a physical RAN setup. It depends a k8 cluster which can be deployed using k8 repository that can help to create a multi-node cluster.

To set up the 4gc repository, you need to provide the following:

1. Node configurations with IP addresses in the host.ini file.
   • You can specify both master and worker nodes.
2. Aether configuration parameters, such as RAN_Interface, in the ./var/main.yaml file.

To download the 4gc repository, use the following command:

git clone https://gitlab.com/onf-internship/4gc.git
git clone https://gitlab.com/onf-internship/k8s.git

Step-by-Step Installation

To install the 4g-core, follow these steps:

1. Set the configuration variables in the vars/main.yaml file.
   • Set the "standalone" parameter to deploy the core independently from roc.
   • Specify the "data_iface" parameter as the network interface name of the machine.
   • Set the "values_file" parameter:
     • Use "sdcore-4g-values.yaml"
   • The "custom_ran_subnet" parameter, if left empty, core will use the subnet of "data_iface" for UPF.
2. Add the hosts to the init file.
3. Run make ansible.
4. In the running Ansible docker terminal:
   • Make sure you have dployed a k8 cluster using k8s-install from k8s repo.
   • run make 4gc-install
   • It creates networking interfaces for UPF, such as access/core, using 4gc-router-install.
   • Finally, it installs the 5g core using the values specified in 4gc-core-install.
     • The installation process may take up to 3 minutes.

One-Step Installation

To install 4gc in one go, run make 4gc-install.

Uninstall

• run make 4gc-uninstall
