It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
When the performance of the multi-wavelength path is optimized in the existing network management system, the performance optimization of each optical device in the single-wavelength path must be completed based on the upstream device, so that the performance optimization of the optical devices in the single-wavelength path must be optimized and adjusted according to the sequence of the path. However, the multi-wavelength paths may have a common path, a single sweep device in the same path cannot execute multiple commands simultaneously, and the parallel optimization adjustment also has a problem of mutual interference, so that the parallel optimization adjustment cannot be directly performed according to the wavelength paths. Currently, a single wavelength path serial mode is adopted for performance optimization. However, the serial mode may prolong the time of the whole performance optimization process, which may cause the failed wavelength path to be unable to be repaired quickly, thereby affecting the user experience.
As shown in fig. 1, the present invention provides a method for fast performance optimization based on multi-wavelength path, which includes:

The single wavelength path class diagram constructed in this step is shown in fig. 3, and the single wavelength path contains the wavelength information of the wavelength path and the path information of all the optical multiplexing sections that have passed through. For example, in fig. 2, a wavelength path 1 includes wavelength information λ 1, and 5 optical multiplexing segment paths (network element 1 — network element 4, network element 4 — network element 6, network element 6 — network element 7, network element 7 — network element 8, and network element 8 — network element 10);
the dependency chain table refers to a data structure, such as an array or a queue, and is not limited herein.
S3, integrating the single wavelength path optical multiplexing section adjusting sequence and the dependency relationship table constructed in the step S2 into a global optical multiplexing section adjusting relationship diagram;
the optical multiplexing segment class diagram constructed in the above step is shown in fig. 3, and each optical multiplexing segment path includes all the carried wavelength information, for example, the optical multiplexing segment 2 in fig. 2 carries three wavelength data λ 1, λ 2, λ 3; each optical multiplexing segment path contains information of a dependent optical multiplexing segment, for example, in fig. 2, an optical multiplexing segment 2 (network element 4-network element 6) depends on information of three preceding optical multiplexing segments (network element 1-network element 4, network element 2-network element 4, and network element 5-network element 4); each optical multiplex section path contains the current adjustment state.

After step S5, some objects that need to depend on other multiplexing segments are updated to be independent, and the independent objects are continuously selected for starting and adjusting when the operations are executed in a recycling manner S4.
