Abstract
Today, the avionics platforms are developedaccording to the Integrated Modular Avionics (IMA) concept, allowing one processing module to host one or several applications in order to reduce Space, Weight, Power (SWaP) and costs. According to this evolution, network architectures were developed inwhich modules are interconnected and communicate through a deterministic network which should support critical inter system communications and also a part of intra system communications. The favored answer fully compliant with IMA platform properties for the Avionic Data Network architecture is a centralized communication system using several Avionic Switches as centralequipment's compliant to the standard ARINC 664 Part 7, which defines a deterministic switched communication network at 100 Mbps per link using an Ethernet frame structure. However, a centralized communication system for some aircrafts or helicopters requiring a "small"Avionics Data Network is a major overhead for the avionics suite in term of size, weight and globallycost like to the fact that to fulfill the constraints of availability and segregation inside the communication system at least a number of 2 or 4 switches shall be used. This negative impact is stressed by the necessity to upload the configuration tables for each location and to monitor A664 part 7 switch as avionics equipment. A promising approach that allows optimizing SWaP (less Size, Weight and Power) than the currentmain A664 Avionic Data Network is the evolution from the centralized communication system to a distributed communication system without anyadditional dedicated communication equipment. Nevertheless, to fulfill issues like data flow latency mastering, segregation, network availability in case of subscriber loss, configuration should beaddressed while keeping the ARINC 664 properties as data flow partitioning, monitoring and frame structure.
