Abstract:
1. In automatically switched optical network operating according to a wavelength plan, a computer-implemented method of selecting a wavelength for an optical path with reduced wavelength SRS transients, comprising: providing a plurality of configurable global variables, configured according to the performance requirements of said network; grouping all wavelengths provided by said wavelength plan into static bins and, based on a plurality of bin constraints, organizing said static bins into subsets of dynamic bins which include all wavelengths available for said optical path; and searching within said subsets of dynamic bins for a wavelength (Lam) that has an individual performance parameter ΔQ (λ) estimated for said optical path above a threshold (Th) and satisfies a maximum number of wavelength constraints, wherein said bin constraints and said wavelength constraints are designed for offering various degrees of SRS transient reduction.
