摘要： A transport control server (100) wherein a conversion table including a pre-conversion identifier and a post-conversion identifier, and a conversion type indicating the aggregate/transfer of a path are previously stored for each two segments that are connected to each other. When devices (111, 118) at the endpoints of the path are specified, the transport control server (100) calculates the route between the devices to identify one or a plurality of gateway nodes (112 to 117) on the route. Also, the transport control server (100) acquires from a storage unit the pre-conversion identifier, post-conversion identifier, and conversion type corresponding to two segments that are connected by the identified nodes for each of the identified nodes, and sets the acquired identifiers and conversion type to each of the nodes. Each of the nodes encapsulates and transmits a received packet including the set pre-conversion identifier using the set post-conversion identifier, or replaces the set pre-conversion identifier with the set post-conversion identifier and transmits the post-conversion identifier in accordance with the set conversion type.

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.

摘要： Provided is a management computer which reduces the workload of an administrator of a network in setting node when the normal network is changed to a network with redundancy. The management computer manages a plurality of nodes that constitute a network accommodating VLANs. The plurality of nodes include a first node and a second node which make a redundancy pair and which divides the network into an active path and a standby path. The management computer stores port management information showing connection relations for respective nodes and identifiers of VLANs allocated to ports of the nodes, and creates the redundancy pair by updating the port management information of the first node such that a VLAN allocated to one of ports of a connected node that is connected to the first node is allocated to one of ports of the first node that is connected to the connected node.
