METHOD AND SYSTEM FOR PROTECTION OF VIRTUAL NETWORK IMAGE AND COMPUTER DATA MEDIA Russian patent published in 2017 - IPC H04L12/46 

FIELD: information technology.

SUBSTANCE: method for protection of a virtual network image includes: editing and definition, by the application level, at least one subnetwork model based on a query for editing the network; building, by the network virtualization level, at least one subnetwork model in accordance with at least one said edited and defined subnetwork model and integrating that at least one built subnetwork model in the global representation of the network, when the global network representation contains at least one protection policy and at least one objective of optimizing image for at least one subnetwork model in order to create spare copies; and displaying, by the controller level, at least one subnetwork model contained in the global representation network, respectively in the operating network of devices and backup network of devices, according to said at least one security policy and at least one image optimisation objective for at least one subnetwork model and when the operating network of devices shows failures, the specified conditions are satisfied, and the backup network of devices shows no failures, switching the operating image of the corresponding network from the operating network of devices to the backup network of devices.

EFFECT: protection of virtual network image.
