What is free5gmano?

This is a 5G MANO (Management and Network Orchestration) project developed that refer to 3GPP TS 28.531, TS 28.532 Release 15 (R15). The purpose is to achieve the management and scheduling of 5G network slices. Please refer to Features for the functions of release. This project is collaborating with free5GC.org. Hence, it can provide as a MANO platform for deploying network slice subnet instances (NSSIs) of free5GC VNFs.

Currently, the major contributors of this project are Department of Computer Science and Information Engineering (Dept. of CSIE) and Center of Infomormation Technology Innovation Services (CITIS), National Taichung University of Science and Technology (NTCUST)

Architecture

It's refer to ETSI GS NFV-MAN 001 V1.1.1

Features

• AllocationNssi API is implemented in Network Slice Subnet Management Function that refer to 3GPP TS 28.531 (R15). It can create a Network Slice Subnet Instance (NSSI) by calling os-ma-nfvo interface, which is the basis of network slicing.
• A Service Mapping Plugin framework is designed to deploy the Network Slice Subnet Instance (NSSI) via os-ma-nfvo APIs and provide the selection of the open source NFV Orchestrators, e.g. Kubernetes-based Kube5gnfvo (default), OpenStack-based Tacker etc.
• Network Slice Subnet Template can assist users to provide ETSI MANO NFVO required information, e.g. VNF Package, Network Service Descriptor

Dependencies

The following packages are required:

• git
• python3
• pip3
• mysql
• NFV-MANO
• Kafka

Getting started

Install NFV-MANO

Option1 - install kube5gnfvo

Please refer to kube5gnfvo Installation Guide to install kube5gnfvo.

Option2 - install OpenStack Tacker

Please refer to OpenStack Tacker Installation Guide to install OpenStack Tacker.

Deploy free5gmano by Kubernetes

git clone https://github.com/free5gmano/free5gmano.git
cd free5gmano/deploy
kubectl apply -f .

Install Kafka

Please refer to Kafka Installation Guide to install Kafka.

Manual install free5gmano

If you have deployed free5gmano by Kubernetes before, you can jump to Apply a NSSI (Network Slice Subnet Instance).

1. Install the required packages

sudo apt -y update
sudo apt install -y python3 python3-pip git libmysqlclient-dev mysql-server
sudo service mysql start

2. Alias python3 to python

sudo alias python=python3
sudo alias pip=pip3

3. Clone nm_manager project

git clone https://github.com/free5gmano/free5gmano.git
cd free5gmano

4. Install python dependencies

pip install -r requirements.txt

5. Apply environment variable

echo 'export FREE5GMANO_MYSQL_USER=<your mysql user>' >> ~/.bashrc
echo 'export FREE5GMANO_MYSQL_PASSWORD=<your mysql password>' >> ~/.bashrc
echo 'export FREE5GMANO_MYSQL_HOST=<your mysql host ip>' >> ~/.bashrc
echo 'export FREE5GMANO_MYSQL_PORT=<your mysql port>' >> ~/.bashrc
echo 'export FREE5GMANO_NM=127.0.0.1:8000' >> ~/.bashrc
echo 'export FREE5GMANO_NFVO=<your nfvo ip>:<your nfvo port>' >> ~/.bashrc
source ~/.bashrc

6. Create a database

mysql -u $FREE5GMANO_MYSQL_USER -p$FREE5GMANO_MYSQL_PASSWORD
CREATE DATABASE free5gmano;

7. Database migrate

python manage.py makemigrations nssmf moi FaultManagement
python manage.py migrate

8. Run the Django server

python manage.py runserver 0.0.0.0:8000

Apply a NSSI (Network Slice Subnet Instance)

Install the nmctl client

Please refer to free5gmano-cli Installation Guide to install free5gmano-cli.

1. Clone simpleexampleplugin project

git clone https://github.com/free5gmano/simpleexampleplugin.git

2. Register a service mapping plugin

nmctl register plugin kube5gnfvo -f simpleexampleplugin/

3. Check service mapping plugin is registered

nmctl get plugin
        name     allocate_nssi     deallocate_nssi
  kube5gnfvo  allocate/main.py  deallocate/main.py

4. Create a VNF Template

nmctl create template -t VNF -n kube5gnfvo
Do you want to download example? [y/N]: y
OperationSucceeded
Template Id: 00936c28-ba30-4604-a134-4f4302acaea7

5. Onboard the VNF Template

nmctl onboard template 00936c28-ba30-4604-a134-4f4302acaea7 -f VNF/

6. Create a NSD Template

nmctl create template -t NSD -n kube5gnfvo
Do you want to download example? [y/N]: y
OperationSucceeded
Template Id: 31e7f5ad-9259-4b9b-97b6-d3ff78996aec

7. Onboard the NSD Template

nmctl onboard template 31e7f5ad-9259-4b9b-97b6-d3ff78996aec -f NSD/

8. Create a NRM Template

nmctl create template -t NRM -n kube5gnfvo
