The Avionics Full Duplex Switched Ethernet (AFDX) backbone constitutes one of the major technological breakthroughs in modern avionic architectures. This network is based on routing Ethernet frames through isolated data tunnels referred to as Virtual Links (VL). VLs can be thought of as multicast trees, each serving for data transmission between one and only one end of the network to several others. Multiple VLs are deployed for exchanging data between avionic systems with a reserved amount of bandwidth.In this paper, we propose different methods to define VL characteristics and to route VLs in the network while minimizing the maximum utilization rate of the links. The proposed methods provide the basis for a more efficient design of the VLs, and have to be completed later on by the verification of the worst-case network latencies. The industrial applicability is shown on experimental results and on a representative benchmark.
