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： A transport control server coupled to a plurality of nodes in a network through which a plurality of traffics passes through is provided. The transport control server is configured to receive bandwidth information from each of the nodes when the traffics pass through the nodes. For each of the traffics, the transport control server calculates bandwidths at an entry edge node and at an exit edge node based on the received bandwidth information. The transport control server defines as a first traffic, based on the calculated bandwidths at the entry edge node and the exit edge node, a traffic having a discarded bandwidth that is larger than a first predetermined bandwidth. Also, the transport control server defines as a second traffic, based on the received bandwidth information, a first traffic having a bandwidth at the two or more nodes that exceeds a specified second bandwidth.

摘要： There is a need to extract a traffic related to congestion in consideration of an entire network. Multiple traffics are received from multiple nodes. There is available information about bandwidths for the traffics passing through nodes. Bandwidths for the traffics at an entry node and an exit node are extracted from the bandwidth information. Each traffic first passes through the entry node and last passes through the exit node. A bandwidth is dropped when the traffic passes through the nodes. The dropped bandwidth is calculated based on the extracted bandwidths for the traffics at the entry node and the exit node. The calculated bandwidth to be dropped is compared with a specified first bandwidth. One or more first traffics are extracted because of having the dropped bandwidth larger than the first bandwidth. Based on band information, a second traffic is extracted from the extracted first traffic. The second traffic has a bandwidth that is dropped at two or more nodes for the first traffic to pass through and exceeds a specified second bandwidth.

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.
