Abstract

Abstract: An optical wavelength routing algorithm for satellite networks based on multi-service was proposed, in order to solve the problem of low utilization rate of wavelengths, slow convergence and low efficiency of satellite optical networks. In this algorithm, it divided the area of the satellite network and updated the link in the area to improve the convergence speed of algorithm. Different services were assigned different wavelength sets to satisfy requirement of different service. According to the initial link weight, which included wavelength remain number and transmission delay, it changed link weight dynamically to achieve network load balancing and rational use of resources. In the MEO/LEO double-layer satellite optical networks, the simulation results show that the maximum rate of network congestion is reduced by 20% compared with the Traditional algorithm. The maximum rate of wavelength utilization is increased by 10%, and the number of successful requests increased by 10%.
