Open Baton Element Management System for Generic VNFM

This project contains the sources of the Open Baton Element Management System (EMS). The EMS is an AMQP producer/consumer running as an agent inside the deployed VMs for executing the lifecycle events received from the Generic VNFM. After the EMS starts, it connects to the RabbitMQ server, subscribes to the queue with its name and sends register message to the specific register-queue attending further commands from the VNFM. EMS receives requests like clone scripts from specific git repositories, update them and execute with the arguments that were sent within the message.

Technical Requirements

  • python 2.7
  • pika 0.10.0
  • pythonGit
  • git
  • python pip

How to install the Open Baton EMS

The EMS is typically installed by the Generic VNFM. Those are the commands executed by the Generic VNFM (via user-data) while booting the VM for installing the EMS:

apt-get install -y python-pip
pip install --upgrade pip
pip install pika
pip install gitpython
cp /usr/share/zoneinfo/$TIMEZONE /etc/localtime
apt-get install -y git
mkdir /opt/openbaton
pip install openbaton-ems

After the installation make sure you configure the properties file correctly: /etc/openbaton/

What is Open Baton?

Open Baton is an open source project providing a comprehensive implementation of the ETSI Management and Orchestration (MANO) specification and the TOSCA Standard. Open Baton provides multiple mechanisms for interoperating with different VNFM vendor solutions. It has a modular archiecture which can be easily extended for supporting additional use cases.

It integrates with OpenStack as standard de-facto VIM implementation, and provides a driver mechanism for supporting additional VIM types. It supports Network Service management either using the provided Generic VNFM and Juju VNFM, or integrating additional specific VNFMs. It provides several mechanisms (REST or PUB/SUB) for interoperating with external VNFMs.

It can be combined with additional components (Monitoring, Fault Management, Autoscaling, and Network Slicing Engine) for building a unique MANO comprehensive solution.
