The embodiment of the invention provides an optical network logical topology reconstruction method. The optical network comprises a first network, a second network, a third network and a reconstruction controller, wherein the first network comprises a plurality of first sub-networks, the second network is an optical interconnection network based on optical wavelength exchange and comprises a plurality of sub-networks, the third network is an optical interconnection network based on space exchange, and the reconstruction controller determines a target logical optical path connection relation of the third network according to a target logical topology structure of the optical network and target resource configuration of the optical network, and sending the optical path configuration information of the third network to an optical path control device of the third network; the reconstruction controller determines a target logic optical path connection relation of the second network according to the target logical topology structure of the optical network and the target resource configuration of the optical network, determines wavelength configuration information of each first sub-network in the first network, and sends the information to the corresponding first sub-network.
