Title:
CROSSTALK SENSING-BASED DEDICATED PROTECTION SPECTRUM ALLOCATION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/004903
Kind Code:
A1
Abstract:
The present invention relates to a crosstalk sensing-based dedicated protection spectrum allocation method and system, the method comprising calculation, fiber core selection, modulation format and spectrum allocation, and comprising: first establishing a working path: selecting a modulation format; determining a maximum allowable cross crosstalk value, classifying fiber cores, calculating inter-fiber core crosstalk values of all available spectrum blocks, and selecting the spectrum block the crosstalk value of which is the lowest for distribution; and then establishing a dedicated protection path again: selecting a modulation format; and determining a maximum allowable cross crosstalk value, classifying fiber cores, calculating inter-fiber core crosstalk values of all available spectrum blocks, and selecting the spectrum block the crosstalk value of which is the lowest for allocation. According to the present invention, the spectrum resource efficiency of a space division multiplexing elastic optical network is improved, the cross crosstalk value of each optical fiber link is reduced, and the survivability of the space division multiplexing optical network is achieved.
