Head-End Management System over Fed4FIRE - HEMOSF Experiment

                                   logo FED4FIRE


Fed4FIRE is an Integrating Project under the European Union’s Seventh Framework Programme (FP7) addressing the work programme topic Future Internet Research and Experimentation.

Experimentally driven research is considered to be a key factor for growing the European Internet industry. In order to enable this type of RTD activities, a number of projects for building a European facility for Future Internet Research and Experimentation (FIRE) have been launched, each project targeting a specific community within the Future Internet ecosystem. Through the federation of these infrastructures, innovative experiments become possible that break the boundaries of these domains. Besides, infrastructure developers can utilize common tools of the federation, allowing them to focus on their core testbed activities.

Fed4FIRE will establish a common federation framework by developing, adapting or adopting tools that support experiment lifecycle management, monitoring and trustworthiness. A large number of existing experimentation facilities in Europe will be adapted to seamlessly integrate in the federation. Such facilities typically focus on different kinds of networking related research or on different communities regarding services and applications. Example domains are optical networking, wireless networking, software defined networking, cloud computing, grid computing, smart cities, etc. Therefore the federation will have to support a very heterogeneous set of requirements. To guarantee that the federation framework meets all of them, representatives of all these FIRE research communities will be actively involved in the definition of the federation architecture. Each of them will also lead the uptake of the Fed4FIRE platform in their specific community. 

The Fed4FIRE federation framework will enable experiments that combine facilities from the different FIRE research communities. To validate the effectiveness of the framework, researchers from different Future Internet areas will be invited through Open Calls to perform innovative experiments using the Fed4FIRE federation.

One part of the business core of Televes is to offer TV devices and TV infrastructure to installers, aggregators and operators. On that product line, Televes has several devices responsible of the TV diffusion over buildings, group of buildings, housing state, etc. One group of these devices located in a building, whose main objective is to adapt the received signal to the distribution system, is called “TV head-end”. This TV head-end contains the necessary devices responsible to provide connection to the building.

The Televes costumer for that kind of products (installers, aggregators and operators) needs to maintain every TV head-end to offer a TV channels for his customers twenty four hours a day, seven days a week. To maintain the effectiveness and to put into value the product of Televes is necessary to have a management system.

The current market has a high demand of new services and management through mobile devices. That version was not prepared to offer new services demanded by users.

For these reasons, Televes has taken the challenge of the creation of a new version of a TV head-end management system in the shortest time possible. In that new version, all services are available using a central server, which all head-ends are connected to. This server acts as security, communications and interfaces manager. When user needs to control a head-end, he has to establish a connection to the server, which makes the link between the TV head-end and the user.

General overview of new version of “TV head-end management system”

Nowadays, the currently version of TV head-end management system has allowed avoiding all the limitations of older versions and also allows offering TV management services over any mobile device or PC, but there is a very important uncertainty about how it works with a high number of users and head-ends interacting to the system.

The HEMOSF experiment consists to test the new head-end management system with a high number of users and TV head-ends connected through a server.

So that, the main issue is to get a complete analysis of the new head-end management TV system in terms of scalability and number of users and head-ends what can be supported combining different kind of services and parameters.

Televes need to obtain the knowledge about the behavior of the system in a real scenario, an analysis to know if the older protocol used can support future services and a high number of users and head-ends needs to be made. Also, we will analyze the possibilities of improvement (like the use of IPV6 )

The results of the experiment will guide us to make the right decisions about the immediate future of the management system because it will allow:

Dimensioning the server for a specific number of users and head-ends.

Knowing the possible existing threshold of number of users and head-ends that the management system and the specific head-end communications protocol can support.

With that knowledge, we will be able to sizing the management system over another server in case this threshold is exceeded, adding other servers working in parallel.


Televes will take advantage of the Fed4Fire capabilities, using multi-testbed environments over networking facility and cloud computing to obtain the necessary knowledge about of the scalability and supporting of future services for the system, guaranteeing the fulfilling of the actual and future demands of users and foreseeing the feasibility to upgrade the platform for future services.
