To guarantee the real-time performance of an avionic optical network, a model of avionic wavelength division multiplexing (WDM) optical network is built with real-time message flow matrix as the input. According to the optimized aim of minimizing the number of wavelengths in a static optical network, a method of wavelength assignment based on multi-tokens with a priority protocol is proposed, and then the analytical transmission delay expression of an end-to-end system in the optical channel is derived from the proposed protocol. The analytical results show that by using the multi-tokens protocol, the number of wavelengths is reduced by 58.1% as compared with the conventional method, The protocol method optimizes the number of wavelengths, and allows their reuse in network implementation. Multi-tokens with a priority protocol can satisfy the real-time performance demands of avionic networks. A comparison between the theoretical calculation and analysis of simulation results shows that the proposed protocol has the prospect of being applied to the design and performance evaluation of avionic optical networks.
