Claim Text:
1. A method for virtual network migration, comprising: locating a source physical node in a regional physical network, wherein the source physical node is a physical node that triggers virtual network migration; obtaining information of a virtual element corresponding to each virtual network on the source physical node and state information of each physical node in the regional physical network, wherein the state information comprises values for multiple capabilities of each physical node in the regional physical network; determining, according to information of the virtual element and the state information, a physical node that can execute virtual network migration in the regional physical network, wherein a threshold is set for each of the multiple capabilities in the state information, and wherein the physical node that can execute the virtual network migration in the regional physical network has values for each of the multiple capabilities that are below the thresholds; reconstructing a mapping relationship between each virtual network and the regional physical network on the physical node that can execute virtual network migration; comparing the mapping relationships of each virtual network; selecting a mapping relationship with minimum migration consumption as a mapping relationship for executing migration; and sending, according to the mapping relationship for executing migration, a migration instruction to a physical node that needs to execute virtual network migration.
