Aircraft cabin data network is a key element in today’s aircraft, where several functionalities of the cabin are grouped in four different security domains. In todays architectures, each domain is normally separated from the others and uses different standards, ranging from ARINC based standards to customized Ethernet. We present here a future of cabin data network, where the main key principle is the use of a common Gigabit full-duplex Ethernet backbone, shared by all domains. As this new network has to be compliant with existing applications and their requirements, a specific Quality-of-Service (QoS) architecture is investigated in this paper. The contributions of this paper are the description of a new network architecture for cabin networks, and the introduction of a scheduling algorithm called Time-Aware Deficit Round Robin (TADRR) enabling an ultra low-latency time-triggered service. We show the benefits of this new architecture via a performance evaluation carried out with the simulator OMNeT++.
