  • Protection method and system in flexible bandwidth optical networks with multi-core fiber
    Patent number: 11387897
    Abstract: The present invention provides a protection method and system in flexible bandwidth optical networks with multi-core fiber. The method includes steps of: selecting an appropriate working path for a connection request, and selecting a working core as a transmission channel on the working path; allocating, on the selected working path and working core, a spectrum resource that satisfies spectral continuity, spectral consistency, and a crosstalk threshold constraint; selecting, for the connection request, a dedicated protection path that does not intersect a link of the working path, and selecting a protection core as a transmission channel on the protection path; and finally, allocating, on the selected protection path and protection core, the spectrum resource that satisfies the spectral continuity, the spectral consistency, and the crosstalk threshold constraint.
