The present invention provides an optimization method and system for minimizing network energy consumption based on traffic grooming. The method includes: generating a set of service requests in an elastic optical network, and calculating a reachable node set of shortest paths from source to destination nodes for each service request; establishing a virtual reachable path in the reachable node set of shortest paths; and establishing a target function of an integer linear programming model of the minimizing network energy consumption, and sequentially determining whether a bandwidth capacity constraint of a single spectrum slot, a path uniqueness constraint, a spectrum allocation constraint, and an optical regenerator quantity constraint are satisfied, where if all constraints are satisfied, the service request is successfully established, or if any of the constraints is not satisfied, the service request fails to be established. The present invention helps to improve the energy efficiency of service requests.

The present invention provides a joint optimization method and system for delay and spectrum occupation in a cloud-edge collaborative network. The method includes: initializing a cloud-edge collaborative network, and generating a set of user requests; establishing a target function of minimum average end-to-end delay and minimum spectrum slot occupation of a user request; during processing of each user request based on the target function, sequentially determining whether a node and path selection uniqueness constraint, a mobile edge computing (MEC) server load constraint, a spectrum resource occupation and uniqueness constraint, a spectrum continuity constraint, and a spectrum consistency constraint are satisfied, where if all constraints are satisfied, the user request is successfully processed, and the process turns to step S4; or if any constraint is not satisfied, the user request fails to be processed; and calculating average end-to-end delay and spectrum resource occupancy of the user request.

The present invention relates to a method and system for allocating a dedicated protected spectrum based on crosstalk awareness, including calculation, core selection, a modulation format, and spectrum allocation. First, working paths are first established: selecting a modulation format; determining a maximum allowable crosstalk value, classifying cores, calculating inter-core crosstalk values of all available spectrum blocks, and selecting a spectrum block with the smallest crosstalk value for allocation; and then dedicated protection paths are established: selecting a modulation format; determining a maximum allowable crosstalk value, classifying cores, calculating inter-core crosstalk values of all available spectrum blocks, and selecting a spectrum block with the smallest crosstalk value for allocation. The present invention improves the spectrum resource efficiency of a space-division multiplexing elastic optical network, reduces a crosstalk value of each fiber link, and implements the survivability of a space-division multiplexing optical network.
