  • To solve real-time performance evaluation problem in avionics wavelength division multiplexing (WDM) network, a method of end-to-end maximum delay calculation during multihop period message transmitting in WDM virtual topology was provided, based on network calculus analysis theory. A network model of the wavelength routing WDM networks was built, and then the composed parts of the end-to-end delay were analyzed. Concerning the communication model of the wavelength routing WDM networks based network calculus analysis theory, a concisely analytical expression was derived for message maximum delay passing through single and multiple wavelength routers. And then treatments of the expression which resolving the problem of the overextended burst were modified to obtain the closed upper bound of maximum delay according to the actual system of avionics. Finally, the evaluated method was testified by the simulation results on OPNET.
