Specification : OpenStack, OSM, NFV, MANO, VNF Onboarding

NFV-MANO Lab Architecture

osm-lab

  Specification

  • OS : Ubuntu 20.04
  • vCPU : 4
  • RAM : 8GB
  • Storage : 40 GB

Requirements

  1. Openstack environment (Check installation on https://luthfi.dev/posts/install-openstack-aio-with-kolla-ansible-in-ubuntu/)
  2. Connectivity between Openstack & OSM

 

 

Summary Steps

  1. Install OSM
  2. Add Openstack (NFVi) to OSM MANO via VIM
  3. Preparing images, network, keypair, security groups on openstack (day-0)
  4. Creating & Onboarding VNF Packages
  5. Verify & testing

 

This my VM for OSM

osm-lab

1. Add regular user

If your VM not have regular/ubuntu user, please add first because for installation later.

adduser ubuntu
usermod -aG sudo ubuntu
su ubuntu
cd ~

osm-lab

2. Download & Install OSM Packages

This steps all packages will installed automatically with 1 command, and OSM Component running as container/POD on top off Kubernetes.

wget https://osm-download.etsi.org/ftp/osm-12.0-twelve/install_osm.sh
chmod +x install_osm.sh
./install_osm.sh

To continue installation, please press Y This installation takes 15-20 minutes, let’s drink coffee first hehe.

osm-lab

For more detail about optional installation, you can from official document : https://osm.etsi.org/docs/user-guide/latest/03-installing-osm.html

3. Verification after installation

Installation success

Make sure your installation like bellow :

osm-lab

POD Status

kubectl get pod -A
kubectl get svc -A

osm-lab

OSM Dashboard

Open your OSM Dashboard with External IP from SVC, above steps.

osm-lab osm-lab

4. Open Your Openstack

Before add Openstack to MANO, we need understand VIM URL (Openstack URL), in this case openstack using keystone/identity services using port 5000

Our VIM URL : http://172.12.12.254:5000/v3/

osm-lab osm-lab

5. Add Openstack NFVi to MANO (VIM)

VIM is one of MANO component, this function for handle nfvi like openstack, vmware, cloud, and others.

Add Openstack to VIM Accounts, like bellow:

osm-lab

Write about your openstack (NFVi) information

  1. Name : your VIM Account name
  2. Type : Your NFVi type
  3. VIM URL : Your openstack keystone API, (check above)
  4. VIM Username : Your openstack user
  5. VIM Password : Your openstack password
  6. VIM Project/Tenant : Your openstack project will use for VNF
  7. Config : This section you need if you using HTTP for connection & use floating IP for VNF management later.

osm-lab

Make sure your NFVi connected to MANO

osm-lab

6. Preparing openstack environment (Day-0)

This section we prepared first images & network. Actually depends from your VNF Packages will use existing resources (network, keypair) or created new one.

A. Internal Network

In this case, we create new internal network named mgmt for network management VNF & use floating IP for external connection, need connect to external network with router.

B. Images

C. Security Groups

Understanding about VNF & NS Packages in this Lab

osm-lab

Create VNF & NS Packages is preety complex to understand, because here named of VM (Virtual Machines) not a VNF again but vDU (Deployment Unit) & others complex term.

So to simply this, we created simple VNF Packages with 1 vDU (VM), and create NS Packages (Network service) for connect eth0 to mgmt network & eth1 to inside network.

Meaning

  1. vDPU (Virtual Deployment Unit)
  2. VNFD (Virtual Network Function Descriptor)
  3. NSD (Network Service Descriptor)
  4. VLD (Virtual Link Descriptor)
  5. CP (Connection Point)
  6. ICP & ECP (I=Internal, E=External)
  7. NST (Network Slice Template)
  8. And many more.

If you interest to understand more about VNFD, NSD & NST you can check on official OSM : https://osm.etsi.org/docs/user-guide/latest/05-osm-usage.html

 

7. Upload VNF Packages

Download simple VNF Packages here : https://github.com/assyafii/vnf-example-packages

First, upload VNF packages

osm-lab

Then, upload NS packages

osm-lab

8. Onboarding Packages

Just click instantiate, OSM Will created VM & Others from packages.

osm-lab

Choose your VIM Accounts will deployed

osm-lab

Wait for it

osm-lab

Yeay, VNF & NS Success onboarding

osm-lab

9. Verification

This step you can verify from NFVi (Openstack) side

You can see here, VNF Already created & have Floating IP

osm-lab

NS Already created also

osm-lab

You can access using Floating IP & Password used cloud_init.cfg defined before in vnfd

osm-lab

All Official Packages

You can check all references packages (VNFD, NSD, NST) here for use cases :
