My Project

Here is an overview of architechture of project.

System Architecture

The following diagram illustrates the architecture where:

• UE (Client): User Equipment requesting data.
• gNodeB: Base station that communicates with the UE and contains a cache proxy.
• Cache Proxy: Caching component running on the gNodeB.
• Data Network (DN): The server providing the requested data.

Deploy the core network

oai-cn5g-fed/docker-compose$ docker-compose -f docker-compose-basic-vpp-nrf.yaml up -d

For running 5G RAN using UERANSIM

git clone -b docker_support https://github.com/orion-belt/UERANSIM.git

cd UERANSIM docker build --target ueransim --tag ueransim:latest -f docker/Dockerfile.ubuntu.18.04 .

oai-cn5g-fed/docker-compose$ docker-compose -f docker-compose-ueransim-vpp.yaml up -d

To check the logs

docker logs ueransim

Ping UE from external DN container.

docker exec -it oai-ext-dn ping -c 3 12.2.1.2

nat port forwarding

sudo sysctl -w net.ipv4.ip_forward=1

sudo iptables -t nat -A POSTROUTING -o enp0s3 -j MASQUERADE

sudo systemctl stop ufw

sudo iptables -I FORWARD 1 -j ACCEPT
