Now replaced by NBI

VDU

Virtual Deployment Unit

What is juju?

charm

is a set of action and hooks

actions are programs

hooks are events and signals

LXC - Linux Containers

is an operating-system-level virtualization method for running multiple isolated Linux systems (containers) on a control host using a single Linux kernel

cgroups limitation and prioritization of resources (CPU, memory, networking)

namespace isolation isolation of working environment including processes, networking, users and filesystems

LXD

system container manager.

Hypervisor, but for linux containers

Uses prebuilt images

Under the hood, LXD uses LXC through liblxc and its Go binding to create and manage the containers.

PDU

Protocol data unit

There are several isolation programs available

• ETSI-hosted open source management and orchestration (MANO) community project
• yang parser to parse NTCONF
• git pull –rebase before pushing changes
• OSM commit-msg hook
• Run OSM on vagrant

In order for OSM to work, it is assumed that:

• Each VIM has an API endpoint reachable from OSM
• Each VIM has a so called management network which provides IP address to VNFs
• That management network is reachable from OSM
• OSM client, a python-based CLI for OSM, will be available as well in the host machine. Via the OSM client, you can manage descriptors, NS and VIM complete lifecycle.¹

Supported VIMs¹

1. OpenVIM
2. OpenStack
3. VMware vCloud
4. AWS

OSM directories

• /usr/share/osm-devops/
• /etc/osm - db password and all

NBI - North Bound Interface²

• REST-full following ETSI SOL005 standard
• Runs inside a docker container
• Basic authentication or no authentication is also possible changing ‘nbi.cfg’ file
• From the architecture it looks like osmclient and lightui are using NBI
• management network (sometimes called OAM network) is created

To be able to serve a site on HTTPS from localhost you need to create a self-signed certificate³.

Capabilities of vim-emu? What can it do?

• Runs experiments on vim-emu, its a client. Takes a PED file and output directory to store results

• tng-sdk-package packs/unpacks .tgo files based on TOSCA specifications
