<p>Provided are a planning method and device for a wavelength division multiplexing network. The method comprises: conducting mapping on each physical node in the physical topology to form a double-layer topology; for each service, if there is an OCH capable of bearing the service and passing through an end node of the service in the double-layer topology, for each existing OCH, forming a pseudo logical link for a logical link corresponding to the OCH according to the end node of the service; and calculating a service route of the service in the double-layer topology, and determining the OCH on the service route and a physical route corresponding to the OCH, so as to obtain a first planning result. The technical solution of the present invention can improve the efficiency of planning a wavelength division multiplexing network.</p> |
