Abstract
Described is a method for managing the traffic protection in OMS-SPRING networks and allowing the wavelength allocation change in the traffic transit nodes. The method of managing the traffic protection in an OMS-SPRING network should a span of the path fail is characterized in that it comprises the steps of providing a wavelength interchange mechanism; performing a ring Span Switch action by the OMS-SP mechanism; and re-routing the wavelength interchanged path on the protecting wavelength corresponding to the working wavelength of the span affected by a failure.
