<p>A wavelength routing method based on wavelength division multiplexing optical network is disclosed by the present invention, which includes: setting reserved channels of all fibers in the network (101); when determining a recovery path for interrupted service, using wavelengths of the reserved channels to perform wavelength routing assignment for the recovery path (102). A wavelength routing system is also provided by the present invention. According to the present invention, the quantity of total wavelengths of fibers occupied by wavelength routing for the recovery path is reduced and the wavelength utilization rate is improved.</p> |
