    摘要: From among a U-plane and a C-plane, the U-plane is installed in a first user site which has a base station, and the C-plane is installed in a C-plane site (any site that is not a user site). A system sets a U-plane inter-site path which is an inter-site communication path that connects a first user site with a second user site via a wide area network, and a C-plane inter-site path which is an inter-site communication path that connects a C-plane site with the first user site via the wide area network. In addition, the system sets an in-site communication path which is a communication path within the first user site and which connects to an inter-site communication path. A U-plane inter-site path is an inter-site communication path via which data is transmitted or received by a U-plane. A C-plane inter-site path is an inter-site communication path via which a signal is transmitted or received by a C-plane.

    摘要: When a communication path between a user site and a dual-homed data center is made redundant, a communication between the user site and a server within a data center can be continued. An edge node DCE-1 of a data center 40-1 and edge nodes TPE-1, TPE-2 of a transport network are connected to each other by a link TPE-1-1 and a link TPE-2-1, respectively. The edge nodes TPE-3 and TPE-1, TPE-2 that hold a node AE51 of a user site 50 are set with an LSP 110 of an active system, and an LSP 120 of a backup system, respectively. One of the links is active, and the other link is backup, and the LSP of the TPE node having the active link in the LSP 100 and the LSP 120 is made active. The respective links are prioritized, and the links are switched to an active state in order from the links higher in the order of priority when a link failure or an LSP failure occurs.

    摘要: To reduce a load of an inspection process on a server apparatus . A computer system includes a server apparatus, a gateway apparatus, and a plurality of devices coupled to the gateway apparatus. The gateway apparatus retains a range of a normal value of a device, calculated based on device information, for the plurality of devices, and when device information related to a certain device is not included in a range of a normal value of the device, notifies the server apparatus of the fact that an anomaly with respect to the device has been detected. When the server apparatus receives from the gateway apparatus a notification of the fact that an anomaly has been detected, the server apparatus inspects device information related to the device in which the anomaly had been detected.

    摘要: A network system comprises a communication facility, and a management apparatus. The communication facility includes a wireless base station, a data processing apparatus, and communication processing apparatuses. The management apparatus manages resource management information for managing, as a resource, a value of an item to be set for the communication facility to generate a network slice for each of characteristics of the network slice. The management apparatus generates the network slice, refers, based on a characteristic of the network slice, to the resource management information to determine the value of the item and transmits, to the communication facility, first setting information for setting the determined value of the item. The management apparatus generates a transfer rule by associating identification information on a wireless terminal and identification information on the data processing apparatus with each other and transmits, to the communication facility, second setting information for setting the transfer rule.
