AeroRing: Avionics Full Duplex Ethernet Ring with High Availability and QoS Management

Abstract : The avionics standard AFDX has been introduced to provide high speed communication for new generation aircraft. However, this switched network is deployed in a full redundant way, which leads to significant quantities of wires. To overcome this limitation, a new avionic communication network, called AeroRing, is proposed in this paper to decrease the wiring weight, while guaranteeing the required performance and safety levels. AeroRing is based on a Gigabit Ethernet technologyand implements a daisy-chain wiring scheme on a Full Duplex ring topology. First, the main features of such a proposal, and particularly the QoS and robustness management, are detailed. Then, numerical results of some Performance Indicators (PI) are illustrated to highlight its ability to guarantee the avionics requirements.
