Poster Abstract: The Challenge of a Common Core Backbone Network on Future Aircrafts

Aircraft are becoming more and more electronically driven and three mains evolutions are foreseen to occur. Onboard connectivity is to rise for both passenger and monitoring use. Increase of the overall on-board bandwidth consumption and finally, faster configuration modifications, such as shorter cabin evolution cycle. Today aircraft networks are plural and heterogeneous. This complexity and plurality might prevent them to scale to their envisioned future uses. Incentives to investigate for a way to mutualize networking resources therefore arise. A backbone network aboard aircrafts could answer these new trends while reducing overall complexity, cable numbers and technological heterogeneity. We propose an overview of the requirements types for such a network to better understand its challenge.
