Architecting of Avionics Full Duplex Ethernet (AFDX) Aerospace Communication Network
AFDX (Avionics Full Duplex Switched Ethernet) is an avionics data network based on commercial 10/100Mbit switched Ethernet. AFDX uses a special protocol to provide deterministic timing and redundancy management providing secure and reliable communications of critical and non-critical data. AFDX communication protocols have been derived from commercial standards (IEEE802.3 Ethernet MAC addressin...
متن کاملImproving Bandwidth Utilization With Deterministic Delivery Guarantees in AFDX through Traffic Phase-Shifting
The Avionic Full-Duplex Switched Ethernet (AFDX) is a data network certified for avionic operations. AFDX closely follows the IEEE 802.3 (Ethernet) standard for packet forwarding. On top of that, bandwidth enforcement using traffic shaping is performed to provide deterministic delivery guarantees. The design of an AFDX network, however, imposes that bandwidth enforcement is performed at a coars...
متن کاملIncorporating TSN/BLS in AFDX for Mixed-Criticality Avionics Applications: Specification and Analysis
In this paper, we propose an extension of the AFDX standard, incorporating a TSN/BLS shaper, to homogenize the avionics communication architecture, and enable the interconnection of different avionics domains with mixed-criticality levels, e.g., legacy AFDX traffic, Flight Control and In-Flight Entertainment. First, we present the main specifications of such a proposed solution. Then, we detail...
متن کاملQoS-aware AFDX: benefits of an efficient priority assignment for avionics flows
AFDX (Avionics Full Duplex Switched Ethernet) standardised as ARINC 664 is a major upgrade for avionics systems. The certification imposes to guarantee that the end-toend delay of any frame transmitted on the network is upperbounded and that no frame is lost due to buffer overflow. This guarantee is obtained thanks to a worst-case analysis assuming a FIFO scheduling policy of flows on each outp...
متن کاملWorst-case backlog for AFDX network with n-priorities
In most recent avionics systems, AFDX (Avionics Full Duplex Switched Ethernet) is the network used to replace the previously employed point-to-point networks. AFDX guarantees bandwidth reservations by means of virtual links which can be classified with two priority levels. AFDX compliant switches implement output buffers at each switch output port. The stored frames leave each output port accor...
