Abstract
The invention provides a resource allocation method and system in a quantum key distribution optical network. The method includes steps of: setting a topological structure of a quantum key distribution optical network, and initializing parameters in the topological structure; generating a service request, and categorizing a security level of a service according to a security requirement degree of the service, where the security level corresponds to a security score; establishing an optimization objective function to maximize a security score of the quantum key distribution optical network and minimize an occupancy of wavelength and timeslot resources; and establishing a constraint satisfying the optimization objective function, and allocating corresponding wavelength and timeslot resources to the service request under the constraint. The invention implements a joint optimization objective of maximizing a security score of a network and minimizing the occupation of wavelengths and timeslots.
