Abstract: A transfer apparatus is configured to: calculate a total cost of a first route in a first network that starts from a source transfer apparatus and ends at a destination transfer apparatus; obtain a particular cost being a cost between the source transfer apparatus and a first line, which couples the source transfer apparatus and its own transfer apparatus, in a second route, which starts from the source transfer apparatus and reaches the destination transfer apparatus via its own transfer apparatus; calculate a differential between the total cost and the particular cost; set, based on the differential, a cost between its own transfer apparatus and a second line, which couples its own transfer apparatus and the destination transfer apparatus, to a value that causes the source transfer apparatus to select the second route rather than the first route; and notify the cost value to the source transfer apparatus.

Abstract: In some examples, a computing device may receive sensed data of a first sensor sent in a first transmission. The computing device may associate a first timestamp with the sensed data. Further, the computing device may receive, from other sensors, first signal strength information including first signal strength data and a first signal property related to the first transmission, and a second timestamp corresponding to detection of the first transmission. The computing device may receive, from other sensors, second signal strength information including second signal strength data and a second signal property related to a second transmission, and a third timestamp corresponding to detection of the second transmission. When the third timestamp is later than the first timestamp and the first signal property matches the second signal property, the computing device may indicate that a sensor that sent the second transmission is associated with an anomaly.

Abstract: A communication system is capable of re-examining an allocated communication path and a reserved communication path and implementing a rapid service provision in which a resource utilization efficiency is high without an interruption of service or an abrupt deterioration of quality when a reserved communication path is created in advance, and a reserved communication path is allocated according to an allocation request of a user. A communication path with quality assurance of data communication is implemented in a communication network with a communication path calculation device having a communication path managing unit and communication path calculating unit. The communication path managing unit manages reserved communication paths with quality assurance constructed based on a quality assurance communication path construction request of a communication system administrator and a use communication path allocated from among the reserved communication paths according to the quality assurance communication path allocation request of the communication network user.

Abstract: In some examples, a computing device may receive sensed data information sent in a transmission by a first sensor, the sensed data information including a sensor identifier and sensed data of a first sensor. The computing device may associate a first timestamp with the sensed data information. Further, the computing device may receive, from other sensors, radio signal strength information including signal strength data related to the transmission and a second timestamp corresponding to detection of the transmission. The computing device may determine a location of the first sensor based on the signal strength data received from the other sensors. In addition, the computing device may associate the location with the sensor identifier of the first sensor based on comparing the first timestamp with the second timestamp. In some cases, one or more second sensors may forward the transmission from the first sensor to the computing device.

Abstract: A transport system comprises a transport apparatus, which is used to construct a transport network using MPLS-TP; and a control apparatus for establishing a path in the transport network. The transport apparatus is coupled to a transfer apparatus, which is used to construct a transfer network using a network protocol different from an MPLS-TP protocol and uses the network protocol to establish a path in the transfer network in an autonomous distributed manner. The control apparatus and the transfer apparatus use the network protocol of the transfer network to transmit/receive, via the transport apparatus, control messages for controlling the transfer network. The transport apparatus avoids notifying the transfer apparatus of the fact that the control apparatus is not in a normal state, in a case where the path established in the transport network is determined as the normal state, even the control apparatus is determined as the abnormal state.

Abstract: A system for managing a network system including an edge server on which an application is executed and a core network of a mobile network connected to the edge server is constructed. The system sets a parameter value group determined by using a setting template associated with an application requirement suitable for an application requirement of the user in the network system. The setting template includes a template parameter value (a parameter value as a template) for each parameter item related to the network system. The system monitors a status of the network system in which the parameter value group is set, and updates the setting template or determines a value displayed based on the setting template based on a result of the monitoring.
