Virtual network function migration method and device, electronic equipment and storage medium

The invention is suitable for the technical field of network security, and provides a virtual network function migration method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining the deployment information of a virtual network function in a physical network; according to the deployment information, calculating whether each virtual network function in each physical node has a virtual network function of which the coexistence time exceeds a preset duration threshold or not, if so, determining the virtual network function as a virtual network function to be migrated, and obtaining a virtual network function set to be migrated; determining a migration strategy set of the virtual network function set to be migrated; and selecting an optimal migration strategy from the migration strategy set according to a preset near-end strategy optimization algorithm, and migrating the virtual network function to be migrated. According to the embodiment, the security and stabilit
