Description

technical field

[0001] The invention relates to an intelligent optical network, in particular to a method for obtaining a path with a protection entity in an intelligent optical network. Background technique

[0002] The current transmission network is mainly based on SDH (Synchronous Digital Hierarchy) / SONET (Synchronous Optical Network) technology. In actual equipment operation, end-to-end service configuration is mainly manually configured according to customer needs. In order to improve the operability of the transmission network, the concept of intelligent optical network has been proposed internationally, and its main function is to support end-to-end automatic configuration of services. In order to provide automatic service configuration capabilities on the transmission network, intelligent optical network equipment must have end-to-end automatic calculation capabilities for optimized service paths. The original transmission network itself has complete protection cap...
