统一航空电子WDM光网络容错建模研究

The modeling of WDM optical network for Unified Avionics Network

依据未来航电发展方向之一—统一航电网络(Unified Avionics Network,UAN)的要求,研究提出了一种基于WDM(Wavelength Division Multiplexing,WDM)技术的光网络模型作为UAN网络选择,分析了统一航电WDM光网络的适应性与可行性,并建立了统一网络的模型,采用边缘接入网与骨干网互连的组网方式,以最小的代价支持新接入的节点正常工作,保证网络的可扩展性。同时,研究应用团状网与超立方体网网络模型作为骨干网的拓扑结构,并分析了网络链路检测到故障时,系统采用重构的计算方法重选网络的路径,以保证系统恢复,保证网络的正常工作,并提高系统的可靠性。

With the development requirements of future avionics-Unified Avionics Network （UAN）, the paper proposes a kind of selection of UAN based on Wavelength Division Multiplexing（WDM） optical network. The applicability and usability are analyzed for UAN optical network, and the model of UAN is built. The model networking composes of the edge access network and backbone network. The network can communicate with the new access node by the lowest cost, and the model guarantees the extendibility of the UAN network. The paper applies the complete graph and hypercube model as the backbone network topology architecture. When the network link is detected, the system uses the reconfiguration to calculate the network routing ; therefore, the reconfiguration can ensure the restoration of the network, ensure the regular work and improve the reliability of the system.
