Aim of the workshop
Multicasting is well-established in satellite communications, in particular for efficient distribution of media content using satellite constellations as the network of intermediaries. It has been used very little in the context of transport – the aim of the workshop is to present currently available technologies and assets to the transport sector, explore applications and business models for use of these assets and identify technical and commercial challenges that must be overcome to exploit multicasting technology in the transport sector.

The European Space Agency (ESA) is Europe’s central institute for the development and commercialisation of space-related technologies. In addition to flying missions and managing off-planet assets, ESA’s remit includes support for the exploitation of space-technologies to overcome terrestrial challenges. ESA support for technology development ranges from expert input through provision of test-beds or demonstrator facilities to direct funding of development activity.
ESA has invited Transport Systems Catapult to host a workshop on multicasting technology and its applications in the transport sector, with a view to establish collaborations for development and roll-out of new multi-casting based services.
“Multicasting” refers to a mode of information dissemination, where one source (satellite, radio antenna etc.) transmit one data package to a network of trusted intermediaries; each intermediary duplicates the data packages and transmits to end-users that require it. The advantages of multicasting are threefold:
- Reduced load on source – only one data package is sent by source, instead of one package per end-user (see image, right);
- Improved efficiency – data is sent only to end-users that have requested, avoiding unnecessary use of bandwidth and computing resources;
- Improved security – the network of intermediaries provides local control over end-users that receive data.
With increasing amounts of data being generated by transport users and affecting user behaviour in real-time, it is becoming more and more important to manage this Big Data stream efficiently. The technical advantages offered by multicasting can contribute to successful adoption of data-driven real-time transport management, provided multicasting technology can be applied in the transport sector.
