Abstract: A method includes: determining, by the control device, that a site receives a first service; determining that a mapping wavelength of a first service is blocked on an original routing path, where the original routing path includes a first line board connected to a first local dimension, and a wavelength occupied by the first local dimension includes the mapping wavelength of the first service; and routing, by the control device, the first service to a second line board connected to a second local dimension, where the mapping wavelength of the first service is available in the second local dimension.

Abstract: A method includes: obtaining a transmission bandwidth granularity G1 of a target service and an optical-layer spectrum resource of a target fiber channel corresponding to the target service, where the optical-layer spectrum resource includes N consecutive frequency slots, and all of the N consecutive frequency slots have a same spectrum bandwidth; determining a target spectrum slice from the N frequency slots based on the transmission bandwidth granularity G1, where the target spectrum slice includes N1 consecutive frequency slots, and the target spectrum slice includes at least G1 consecutive idle frequency slots; and allocating the G1 consecutive idle frequency slots included in the target spectrum slice to the target service.
