PROBLEM TO BE SOLVED: To shorten operation time of version update of equipment, and to shorten service order input regulation time.SOLUTION: An active system device 2a includes: virtual hosts 212a and 213a implemented by a hypervisor 211a; and a network processing part 22. The active system device 2a executes a sequence Q22a for, when the old virtual host 212a as an old version is implemented by the hypervisor 211a, starting and implementing the new virtual host 213a as a new version; a sequence Q24 for synchronizing configuration information and state information between the old virtual host 212a and the new virtual host 213a, a sequence Q30a for allowing the old virtual host 212a to regulate a service order, a sequence Q31a for allowing the old virtual host 212a to replace a role with the new virtual host 213a and a sequence Q33a for allowing the new virtual host 213a to release the regulation of the service order. |
