Research on Static Routing and Wavelength Assignment Method Based on K-SP Alternative Routing and Genetic Algorithm

Aiming at the problem that the upper layer applications of 5G technology and Internet of Things in the future require low blocking rates for optical network service connections, this paper proposes a static wavelength routing assignment method based on improved K shortest path and genetic algorithm. Based on the idea of adding alternative supplementary path to each link of shortest path, a new and improved method of K shortest path is proposed. On this basis, a static routing and wavelength allocation method based on genetic algorithm is proposed to realize the optimal resource allocation of static traffic flow connection establishment request set. Simulation results show that the proposed algorithm can solve the static routing and wavelength assignment problem well.
