43 results about "Virtual optical network" patented technology

The application relates to a resource allocation method and system based on virtual optical network mapping. The method comprises the following steps: obtaining a virtual optical network; calculating a first time delay resource sensitivity according to a virtual link, and generating a virtual link mapping set in descending order according to the first time delay resource sensitivity; calculating a second time delay resource sensitivity according to a physical link, and generating a physical link mapping set in descending order according to the second time delay resource sensitivity; calculating a shortest path of the physical link, and generating a space division multiplexing data center elastic optical network mapping graph according to the shortest path and the second time delay resource sensitivity; mapping the virtual link to the physical link according to the space division multiplexing data center elastic optical network mapping graph, the virtual link mapping set and the physical link mapping set, and generating a first mapping result; mapping the virtual node to the physical node according to the first mapping result, and generating a second mapping result; and allocating a frequency spectrum resource according to the second mapping result. The purpose of improving resource efficiency and network resource utilization rate is achieved.
