User reports from Fed4FIRE experimenters

A new travel experience is emerging, thanks to Fed4FIRE project, SilverWolf- developed by Televic Rail and iMinds. Silver Wolf offers a ground-breaking, real time monitoring fleet manager for trains. It also provides passengers with Wi-Fi connection and trip management services along with data transfer and passenger information system. More than 22.000 rail cars including Eurostar are now fitted with this equipment.

”The Fed4FIRE virtual wall facility became a test platform on which we could emulate a wayside server infrastructure and a large train fleet, each deploying multiple applications which can be updated using iSync” says Dirk Van Den Wouwer, R&D and Product Manager at Televic.

The challenge

The ability to test complex communication products in an integrated, end-to-end way at scale, before they can be released to the market, is crucial. Fast-track tests are important for companies such as Televic Rail and iMinds as an innovative supplier of Passenger Information System. The main challenge faced by many Small & Medium sized Enterprises (SMEs) is their financial limitation to execute their tests as efficiently as possible.

SMEs under FIRE’s resolution

Projects such as Fed4FIRE overcome this challenge by offering various experimentation opportunities Thus, via Fed4FIRE entrepreneurs can deploy multiple, repetitive and realistic tests to validate their credibility. Fed4FIRE is an Integrating Project under the European Union’s Seventh Framework Program (FP7) addressing the work program topic Future Internet Research and Experimentation (FIRE). Through FIRE facilities, innovative experiments and infrastructure developers are able to apply their core testbed activities and get fast testing results. In this vein, Fed4FIRE has provided TeleVic’s project, Silver Wolf with splendid support to execute their innovative experiment by offering world class European experimentation resources, test beds along with technical and even financial support.

Harnessing Fed4FIRE for Silver Wolf

Indeed, the SilverWolf project verified its iSync functionality with a large fleet of railcars via Fed4FIRE.

“iSync is a means to provide communication between applications onboard trains and their counterpart at wayside. Given some operators manage a train fleet of 30,000 vehicles, thus, only robust provisioning systems can survive. Since updates can be done on fleet in service it is undesirable to perform the first tests on the fleet directly. Therefore, the Fed4FIRE virtual wall facility became a test platform on which we could emulate a wayside server infrastructure and a large train fleet, each deploying multiple applications which can be updated using iSync” says Dirk Van Den Wouwer, R&D and Product Manager at Televic.

“Based on the provisioning systems’ needs, we have set up various configurations with adjusted Virtual Machines (VMs). Each VM represents a set of trains which all could be addressed individually from the emulated wayside server infrastructure that resides in a VM. Various combinations of fleet sizes, number of manageable applications and data sizes provided us valuable insights in order that developers enhance the robustness and scalability of the deployed iSync application.We found that experiments could be setup very easily because a lot of resources could be accessed with only one tool. The Fed4FIRE consortium provided sufficient support when it was needed to setup new experiments.”

What’s next after Fed4FIRE test beds

The  FED4FIRE project has helped Televic to validate the technology for the exchange of data between trains and ground and to keep the data up-to-date on large fleets of trains. It has also added further value to real economy and has improved citizens’ daily life by offering the future railway experience. As a ground-breaking, real time monitoring fleet manager, Silver Wolf supplies passengers with Wi-Fi connection and trip management services. So far, more than 22.000 railcars including Eurostar fitted with Silver Wolf transform the notion of travelling.

However, there is room for future improvements, according to the post-evaluation results: Using an experimentation facility supported by EU research funding, such as Fed4FIRE does not guarantee its availability on a long term. Thus, enterprises may also be driven to discover alternative experimentation opportunities using commercial public cloud infrastructures.

How many people does it take to find a parking space?

It’s easy to find parking in Santander, Spain. Just open a smartphone app and you’ll see where space is available, thanks to a citywide network of sensors which feeds into a vast data hub.

But could people – or indeed their smartphones – be used to collect, process and distribute the data instead of relying on a centralised server?

Fed4FIRE helped to simulate in real-time this alternative distributed approach using the Smart Santander testbed. Researchers found that 250‑500 mobile users within the city centre area could collect and distribute, via phone-to-phone protocols, data that was 80-90% as reliable as 20-200 centrally-networked sensors. This accuracy is good enough for useful applications, without having to build expensive sensor networks, even for fast-changing situations like finding a free parking space.

Earth, please observe!

Every few hours a host of satellites orbits the planet and beams vast amounts of data and sensor readings back to Earth. Are Cloud services robust enough to integrate and process that data? Can they make it available for commercial services like disaster management software, maritime surveillance or homeland security?

It’s too expensive to answer this question with standard experimental infrastructure, not to mention data security and privacy issues. So the company Elecnor Deimos decided to study this set up – satellite network, ground stations, Cloud services and end-users – in Fed4FIRE. They also tested some of the newer, more experimental networking and infrastructures at the forefront of Internet technologies.

The virtual experiments showed the technical feasibility of their ideas, justifying investment in a small-scale, real-world pilot including a real-time satellite feed.

Heads up! TV streaming for the future

Managing the Internet-based services and optimising data traffic associated with TV streaming is a tricky affair, but the company Televes wanted to be sure its streaming service could meet rising demand.

Combining the BonFIRE platform to simulate streaming servers and VirtualWall for end-user interactions, Fed4FIRE helped Televes to find out how usage and demand affected service quality.

The experiment highlighted some technical issues and helped Televes draw up a solid upgrade plan, giving the company a competitive edge especially in the United States.

Achieving security and privacy in the Cloud is difficult because so many actors are involved: hosts, service providers, federators and more. But the advent of “intelligent protection” makes security more robust as automated agents (small computer programs) can identify breaches and fix vulnerabilities even across complex, virtual and distributed networks.

“Without Fed4FIRE this experiment would have been very difficult, even impossible. The amount of time and cost would have made it unaffordable.”

A Fed4FIRE experiment found that intelligent agents developed by BT were activated within 1 minute of a virtual machine coming online; they also performed well in a network of more than 50 virtual machines. The federated nature of Fed4FIRE helped BT show that the agents had commercial value because they could deploy them across the borders of ownership, location, hardware infrastructure and software.

Untangling wireless…ness

A new protocol called Pragmatic General Multicast (PGM) is currently under development to improve the quality of wireless data transmission. It supports error detection and data packet retransmission simply and without having to increase bandwidth.

“The direct value for us was the availability and access to a very valuable resource of private Cloud testbeds which is usually quite hard to acquire.”

The companies Philips and WOOX Innovations tested an experimental PGM set-up using the w.iLab testbed to see how new PGM systems performed in a real environment with lots of potential interference from other wireless devices. No single facility could have managed such a large-scale experiment with so many prototype devices.

The partners found that devices retransmitted missed packets within a reasonable time, encouraging the partners to pursue development of PGM-enabled devices.

The quality of ‘quality assurance’

Mobile network operators monitor their networks extensively so they can optimise operations and meet service level agreements. But is their monitoring data reliable?

Across such vast, complex networks it would be impossible to assess every potential source of inaccuracy, so Naudit created a virtual network instead. Using Fed4FIRE the company controlled all variables and investigated how different parameters influenced monitoring reliability and accuracy.

Having now updated its algorithms, the company boasts new active network monitoring tools that provide network operators in Europe and America with strong data on which to base business-critical network management decisions.

Locked and loaded: secure Cloud storage

Ever worried about saving confidential, sensitive or personal data to the Cloud?

“By using Fed4FIRE platforms we can reduce the effort … and time for experiments.

Researchers at BT and major security vendors have developed a security service prototype, but they needed to know whether it worked for data stored across several Cloud systems, for example in virtual or syndicated Clouds.

Fed4FIRE’s real-world Cloud infrastructure, linked and managed through APIs the jFed tool suite, proved the prototype service would work. It is now being deployed to enhance the security of commercial Cloud services. Surely, that’s enough to put customers’ minds at rest!
