Abstract: To solve the reliability problem of FC-AE-ASM(Fibre Channel-Avionics Environment-Anonymous Subscriber Messaging) network, based on basic FC-AE-ASM network model, several redundancy structure of the FC-AE-ASM network is introduced. An analysis method of network reliability is proposed. A calculation method of all terminal network reliability and error analysis is developed. Combined with the complexity of the FC-AE-ASM network model that is consisted of multiple FC switches, the effect of link redundancy structure, link reliability and node reliability to network reliability are analyzed.
