Reliability model of avionics WDM optical network

To build the unified avionics network in advanced integrated avionics system, the avionics WDM optical network which includes avionics backbone network and edge network was proposed, and multiple ShuffleNet was applied as the model of avionics optical backbone network. To solve reliability performance evaluation problem in integrated avionics network, a model of avionics task and routing was built, meanwhile, the formula of reliability on avionics task was introduced. An illustration of ShuffleNet model was presented. Through the analysis of reliability of avionics task in ShuffleNet, the system execution time, the number of network nodes and routing hops are the dominant factors that affect the system reliability, and the number of wavelengths has little effects on reliability under the same conditions. The simulation results show that the reliability model of avionics task and calculation method can provide the theoretical basis for the analysis of reliability in avionics system.
