Upper bound computation for buffer backlog on AFDX networks with multiple priority virtual links
Rodrigo Coelho, Gerhard Fohler, Jean‐Luc Scharbarg · 2017
In recent avionics systems, AFDX (Avionics Full Duplex Switched Ethernet) is the network used to replace the previously deployed point-to-point networks. In AFDX networks, nodes are not synchronized and therefore data contention repeatedly occurs at the switches output ports. AFDX switches implement output buffers on each output port to address the data contention issue. Considering the safety critical application of AFDX networks, overflow of these buffers must be avoided at all cost to prevent data loss.
