Open N6-LAN

This project implements the N6-LAN network segment, residing between the UPF (User Plane Function) and the internet, specifically designed to host value-added services or VNFs. The N6-LAN processes traffic received from the UPF before it reaches the internet. The main functionality of the N6-LAN is to steer classified subsets of network traffic to specifically chained network functions (VNFs) for processing, in order to support a desired policy and SLA. This functionality, also referred to as Service Function Chaining (SFC).

Service Functions (vnfs/)

The N6-LAN consists of the following service functions:

• vCache: This service leverages the open-source Squid software to provide a virtual cache functionality
• vIPS: This service functions as a virtual Intrusion Prevention System (IPS) utilizing the open-source Suricata software.

To set up each service function, follow the instructions in the respective README file.

Get Started

This setup utilises Docker and Docker Compose for deployment. Ensure you have them installed before proceeding.

Instructions

# Clone repo
git clone https://github.com/tariromukute/OpenN6LAN.git
# Navigate to project directory
cd OpenN6LAN

Run the services:

• eUPF for the 5G Core data plane
• PFCP Simulator for emulating the PFCP message setting up session
• UE Sim emulating User Equipment (UE) devices
• N6-LAN: For steering the traffic through service functions.

docker-compose -f docker-compose-eupf.yaml up -d
