Rule-based network identifier mapping

A method, comprising:

• storing, in local a storage device, a first mapping that maps a virtual network identifier of a tunnel to a rule for classifying traffic, wherein the virtual network identifier identifies a virtualized network associated with the tunnel;
• generating, for a virtualization manager of a virtual machine, a control packet comprising a representation of the first mapping for a respective local end device;
• and
• obtaining, from a notification packet from the virtualization manger, a second mapping that maps the virtual network identifier to an identifier of the virtual machine and an identifier of the tunnel.

A computer system;

• comprising:
• a storage device;
• a processor;
• and
• a non-transitory computer-readable storage medium storing instructions which when executed by the processor causes the processor to perform a method, the method comprising:
• storing, in the storage device, a first mapping that maps a virtual network identifier of a tunnel to a rule for classifying traffic, wherein the virtual network identifier identifies a virtualized network associated with the tunnel;
• generating, for a virtualization manager of a virtual machine, a control packet comprising a representation of the first mapping for a respective local end device;
• and
• obtaining, from a notification packet from the virtualization manger, a second mapping that maps the virtual network identifier to an identifier of the virtual machine and an identifier of the tunnel.
