Introduction

OSM is a model-driven, ETSI compliant NFV MANO solution that simplifies deployment of VNFs and the composition and management of complex network services. It provides all the tools needed for automated end-to-end service delivery and lifecycle management.

Getting Started

The following steps need to be completed to get OSM installed, configured and running.

• Installation
• Accessing Launchpad
• Configuration
• Packages
• On-boarding
• Instantiation
• Service and Config Primitives
• Termination

Installation

OSM run time requires the installation of NSO, RO and Configuration Manager. Follow the Installation steps for each of these components to get them installed.

Accessing Launchpad

Launchpad provides the user interface to the OSM orchestrator. From the Launchpad user can manage the catalog, compose the NS/VNF descriptors and perform the lifecycle management on Network Services. The launchpad UI can be accessed through URL https://1.2.3.4:8000 where 1.2.3.4 is the ip address of the VM where NSO installed (Google chrome version 50 or later is recommended).

The default username/password for accessing launchpad is admin/admin

Configuration

Launchpad need to be configured with the details of the cloud account and configuration agent account before NS/VNF packages are on-boaded and network services are orchestrated. cloud accounts and configuration agent accounts can be configured from the launchpad UI.

To configure cloud account:

 Click on Launchpad and select accounts to navigate to the accounts configuration page.
 Click on ADD CLOUD ACCOUNT and fill the account details
 NAME: Enter the name of cloud account
 Select Account Type: choose  "Open MANO"
 Under ENTER ACCOUNT  DETAILS
    HOST: Enter the IP address of the VM where openmano is running
    PORT: Enter the port for openmano (Default port is 9090)
    TEANT ID: Enter the tenant id configured in openmano

To configure config agent account:

 From  accounts configuration page,
  Click on ADD CONFIG AGENT ACCOUNT and fill account details
  IP ADDRESS: Address of the Juju server
  PORT: Enter the port where juju server is running(Default port is 17070)
  USERNAME: user name to access juju server
  SECRET:  password to access juju server

Packages

The on-boarding process accepts raw descriptors in yaml format or or a package in gzipped tar format.

A NSD package is defined as follows:

 |-- checksums.txt
 |-- <nsd_name>__nsd.yaml
 |-- README
 |
 |-- vnf_config
 |   |-- <vnf_id>__<member_vnf_index>.yaml
     \-- ...
 |-- ns_config
     \-- <ns_id>.yaml
 |-- icons
     |-- <logo_name>.png
     \..
 |-- scripts
     |-- <script_file>
      \..

This tree structure describes the structure of a complete NSD archive. Only the checksums.txt and the descriptor are mandatory.

 |-- checksums.txt
 |-- <vnfd_id>__vnfd.yaml
 |-- README
 |
 |-- icons
     |-- <logo_name>.ping
     \..
 |-- scripts
     |-- <script_file>
     \..
 |-- charms
     |--trusty
        |<charm_name>
        \..
     \..

All package upload require a "checksums.txt" file to verify the integrity of the archives contents.

The checksums.txt file contains a list of the files in the package and the sha256 hash of each of those files. If the package to be uploaded was,

 |-- checksums.txt
 |-- name1__vnfd.yaml
 |

The checksums.txt file would be,

 93554f7808ac53a5116fd1e0f7bec1d15c7a652a59ee8c3f616aef871d592d3b  name1-vnfd.xml

This cheksums.txt file can be generate using,

 find . -type f | xargs sha256sum > checksums.txt

On-boarding

On-boarding is the The process of submitting an existing VNF package or network service descriptor (NSD) to the Launchpad catalog. On-boarding allows objects in to the launchpad catalog so that they can be instantiated.

On the Launchpad Dashboard, click Catalog.

Note: A (0) after the Catalog label indicates that no catalog entries are associated with the Launchpad. This number increases each time you onboard VNFDs and NSDs into the catalog

Below the Descriptor Catalogs label, click the VNFD tab. Click the icon to onboard a catalog package, and do one of the following:

Navigate to the location of the first VNFD package. Optionally open your operating system’s file manager utility, and drag and drop one or more packages directly onto the Catalog Package Manager. Wait for the package to complete uploading. This process could take several minutes, depending on the complexity of the VNFD. Repeat steps 4 and 5 until you have on-boarded all the VNFDs you want to include in your network service.

The following image illustrates how the Descriptor Catalog appears after you have on-boarded the ping and pong VNFDs:

A network service descriptor (NSD) is the deployment template that describes the network service and its constituent elements, such as virtual network functions, virtual links, and virtual network function forwarding graphs. To on-board a nsd package,

Below the Descriptor Catalogs label, click the NSD tab. Click the icon and onboard a catalog package using any of the following options: Optionally open your operating system’s file manager utility, and drag and drop one or more packages directly onto the Catalog Package Manager. Navigate to the location of the NSD package and click Open.

Wait for the package to complete uploading.

The process could take several minutes, depending on NSD complexity. When a NSD package has been fully on-boarded to the catalog, the new NSD appears in the Catalog Package Manager.

Instantiation

Instantiating an NS is as simple as browsing the catalog and specifying the required input parameters. The Launchpad also provides a detailed view of the underlying compute and network topologies.

To instantiate network service,

1. On the Launchpad tab, choose Dashboard link.
2. Click to select Instantiate.

1. Enter the name of the service, any input parameters and click on "Launch".
