Abstract

Possible evolution of Avionics Full-Duplex Switched Ethernet (AFDX) are currently investigated. Such network should support existing time-constrained avionics flows, as well as new best effort traffic, requiring scheduling algorithms to meet guarantees on avionics flows. Following the current trend of the automotive industry to move toward Audio/Video Bridging (AVB), this paper evaluates an application of the scheduling scheme described in the emerging IEEE 802.1 AVB standard in an avionics switched Ethernet scenario. Results are compared to other common scheduling strategies such as strict priority queuing, and different fair scheduling variants.
