Title:
SHARED PATH PROTECTION METHOD AND SYSTEM BASED ON TIME SLOT PERCEPTION IN QKD OPTICAL NETWORK
Document Type and Number:
WIPO Patent Application WO/2024/092992
Kind Code:
A1
Abstract:
The present invention relates to the technical field of quantum key distribution (QKD) optical networks, and discloses a shared path protection method and system based on time slot perception in a QKD optical network. The method comprises: establishing and initializing a QKD optical network model containing a bearing weight; according to the bearing weight, establishing an alternative working path set and an alternative protection path set; simultaneously taking a protection time slot and an idle time slot into account; and according to a difference value between bearing weights before and after resource allocation, selecting a final working path and a final protection path from the alternative sets, and performing resource allocation. The system comprises a network initialization module, a service request generation module, an alternative path establishment module, a working path selection and resource allocation module, and a protection path selection and resource allocation module. The present invention can effectively improve the success rate of services, the consumption of keys, and the utilization rate of network resources.
