Network system, network management server, and configuration scheduling method, using summed processing time

摘要

A reservation processing is executed according to the configuration request to VPN and network device to inform a user's terminal of scheduled period. In a network system including plural network devices for transmitting a packet and a management server, plural logical networks (VPNs) are formed on the plural network devices. The management server receives a configuration request including configuration data for VPN and configuration desired time from a user's terminal to generate the configuration data for the network device from the configuration data for the VPN. The management server refers to a configuration reservation table to confirm whether free time is available in the same period about all target network devices. If free time is available, the management server makes configuration reservation and configures the target network device in the reserved time. The management server notifies the user's terminal of the reserved time.
