The invention provides a
service recovery method, device and
system in a flexible grid optical network and
electronic equipment, and relates to the technical field of optical transport networks, and the method comprises the following steps of: preferentially selecting a first available
route and a first available resource which meet
service quality requirements and support a current modulation format of a service to be recovered in the flexible grid optical network; restoring the service to be restored; if the first available
route and / or the first available resource do not exist, the
service quality requirement of the to-be-recovered service is met by reducing the spectrum efficiency, and effective
recovery of the to-be-recovered service is realized. According to the method, the adjustability of the modulation format in the flexible grid optical network is fully utilized, the effective
recovery of the service under the existing spectrum resources is realized, the scene limitation of the traditional
service recovery method is eliminated, the
recovery effect of the service under the multi-point fault scene is ensured, the network reliability and the service
survivability are improved, the
resource utilization rate is also improved, and the
service recovery efficiency is improved. The
optical transport network configuration efficiency is improved, and the method has a wide application prospect in the field of optical transport networks.
