Abstract: A conversion device (10) of an embodiment converts a command included in a configuration extracted from a NW device (30) that transfers data in a network, into a command that can be set in a NW device (40) that transfers data in the network. The conversion device (10) generates a configuration that can be input to the NW device (40), on the basis of a command obtained as a result of conversion.

Abstract: A management system includes a conversion device including a first extraction unit that extracts setting content as first summary information for each NW function from first setting data for setting an operation of a migration source NW device, and a conversion unit that converts a system of the first setting data for setting an operation of the migration source NW device into second setting data according to a system of setting data of a migration destination NW device and applies the second setting data to the migration destination NW device, and a checking device including a determination unit that determines whether or not migration of the first setting data to the migration destination NW device has been performed normally on the basis of the first summary information and third setting data applied to the migration destination NW device.

Abstract: A specification unit (15b) specifies a path of traffic on the basis of past flow information. A determination unit (15c) determines a network device on the specified path for traffic related to a designated event.

Abstract: Provided are a network information visualization device, a network information visualization method, a network information visualization program, and a network information visualization system that visualizes useful information in network monitoring and improve reliability of a network. An information acquisition unit (11) acquires network information regarding a VPN network (2) including at least flow information having statistical information regarding communication in the VPN network (2). An association unit (12) associates the flow information with another network information included in the network information and generates associated flow information. A visualization unit (14) generates visualization information in which the flow information is associated with the other network information based on the associated flow information.

Abstract: A management system manages a migration from a migration source NW device to a migration destination NW device among NW devices communicating with another communication device on a network, the management system comprising a conversion unit that converts a system of configuration data for setting an operation of the migration source NW device into configuration data according to a system of configuration data of the migration destination NW device by using a general-purpose parameter table capable of associating each service in a user unit, and applies the configuration data to the migration destination NW device.

Abstract: An analysis device (40) receives an xFlow packet that is generated based on a sampled encapsulation packet and includes information regarding an outer header of the encapsulation packet and statistical information of a flow including the encapsulation packet. The analysis device (40) collates information regarding the outer header associated with information for identifying a user of VPN with information regarding the outer header included in the xFlow packet received by a reception unit (431), and specifies the user of the VPN from which the xFlow packet is transferred.
