Claim 4:
5. A non-transitory computer readable medium storing one or more instructions for causing a computer to operate as a processing apparatus to execute:
virtualizing, by the processing apparatus, hardware;
virtualizing, by a processing apparatus, physical hardware;
providing, by the processing apparatus, a network function by using a virtualized resource;
receiving, by the processing apparatus from a management apparatus that detects a first fault caused in the step of virtualizing the physical hardware, notification data including a first countermeasure for the first fault, wherein the first countermeasure includes a system switching into a standby system and a restart of the standby system;
detecting, by the processing apparatus, a second fault caused in the step of providing the network function and generating detection data including a second countermeasure for the second fault, wherein the second countermeasure includes a restart of the processing apparatus without performing the system switching, wherein the first fault caused in the step of virtualizing the physical hardware and the second fault causes in the step of providing the network function occurred at the same time or within a predetermined period of time;
determining, by the processing apparatus, that the first countermeasure and the second countermeasure conflict with each other,
determining, by the processing apparatus, that the notification data or the detection data satisfy a predetermined condition;
determining, by the processing apparatus, a prioritized countermeasure out of the first countermeasure and the second countermeasure under the predetermined condition; and
executing, by the processing apparatus, the prioritized countermeasure.
