Claim 0:
1. A processing apparatus comprising:
a virtualization control unit, including one or more processors, configured to virtualize physical hardware; and
a network providing unit, including one or more processors, configured to provide a network function by using a resource virtualized by the virtualization control unit,
wherein the network providing unit includes one or more processors configured to:
receive, from a management apparatus configured to manage the virtualization control unit, notification data including a first countermeasure for a first fault caused in the virtualization control unit that is outside the network providing unit, wherein the first countermeasure includes a system switching into a standby system and a restart of the standby system;
detect a second fault caused inside the network providing unit and generate detection data including a second countermeasure for the second fault, wherein the second countermeasure includes a restart without performing the system switching, wherein the first fault outside the network providing unit and the second fault inside the network providing unit occurred at the same time or within a predetermined period of time;
determine that the first countermeasure and the second countermeasure conflict with each other,
determine that the notification data or the detection data satisfy a predetermined condition;
determine a prioritized countermeasure out of the first countermeasure and the second countermeasure under the predetermined condition; and
execute the prioritized countermeasure.
