A method, correlative device and system for virtual network migration are provided. The method of the embodiments of the present invention includes: locating the source physical node in a region physical network; obtaining the virtual element corresponding to each virtual network in the source physical node and the state information of each physical node in the region physical network; determining, according to the virtual elements and the state information, a physical node that can implement the virtual network migration in the region physical network; reconstructing the mapping of each virtual network and the region physical network respectively in the physical node, comparing the mapping corresponding to each virtual network, and selecting the mapping with the least migration consumption as the mapping that implements the migration; sending, according to the mapping that implements the migration, a migration instruction to the physical node that needs to implement the virtual network migration. Furthermore, the embodiments of the present invention also provide the correlative device and system that implement the method. |
