Python version of the vnfm-sdk

This project contains a vnfm sdk for python projects.

Technical Requirements

This section covers the requirements that must be met by the python-vnfm-sdk in order to satisfy the demands for such a component:

  • python 2.7 or 3.5

  • pika

How to install python-vfnm-sdk

The safer way to start is to use a virtal environment. Once activated, just run

pip install python-vnfm-sdk

How to configure your vnfm

The sdk runs a certain number of instances of the vnfm by invoking the method:

def start_vnfm_instances(vnfm_klass, config_file_path, instances=1, **kwargs):
    # ....

where the parameters are the Vnfm class that implements AbstractVnfm, the config file path for the vnfm, the number of instances and the instantiation arguments for the vnfm class.

The ini config file looks like







The type of the vnfm


must be RABBIT


Ip of the rabbitmq broker used by the nfvo


username for the rabbitmq broker used to connect to the manager queue of the nfvo


password for the rabbitmq broker used to connect to the manager queue of the nfvo


exchange name used in the rabbitmq broker by the nfvo


true or false in case you want the endpoint queue to have the autodelete property (usually true)


heartbeat for the rabbitmq connection


path where the logfile will be written

see the python dummy vnfm as example

What is Open Baton?

OpenBaton is an open source project providing a comprehensive implementation of the ETSI Management and Orchestration (MANO) specification.

Open Baton is a ETSI NFV MANO compliant framework. Open Baton was part of the OpenSDNCore ( project started almost three years ago by Fraunhofer FOKUS with the objective of providing a compliant implementation of the ETSI NFV specification.

Open Baton is easily extensible. It integrates with OpenStack, and provides a plugin mechanism for supporting additional VIM types. It supports Network Service management either using a generic VNFM or interoperating with VNF-specific VNFM. It uses different mechanisms (REST or PUB/SUB) for interoperating with the VNFMs. It integrates with additional components for the runtime management of a Network Service. For instance, it provides autoscaling and fault management based on monitoring information coming from the the monitoring system available at the NFVI level.
