Abstract
Based on distributing uniformly virtual network topology links and associated wavelengths to the surface of rotating sphere
a new wavelength rotation graph model of wavelength switching optical network（WSON） was constructed
and a creative method to solve the routing and wavelength assignment（RWA） problems was proposed.The simulation results show that if the wavelength number of each link is set separately to 4 and 8
the average blocking probability of the RWA based on the rotation graph model reduces by 5.03% and 9.71%
and the average resource utilization increases by 3.3% and 1.54% respectively
as compared with the existing model.This method would be useful for solving the problem of optical network RWA which has wavelength conversion capabilities.
