The invention provides a cable abnormality assessment system, a slave device, and a cable abnormality assessment method. A cable abnormality assessment system is provided with a diagnosis control unit for assessing a cable abnormality on the basis of link-up information between a communication unit and another machine connected to the other end of a cable, and first and second information that are the respective results of abnormality diagnosis by a signal line diagnosis unit with regard to one and the other of two pair signal lines of the cable.

The present disclosure relates to a method performed by a cloud node (104) for handling sensor nodes and fog nodes in a communications system (100), wherein the communications system comprises a plurality of sensor nodes (110) located at a plurality of locations, to be handled by the fog nodes (120), the method comprising obtaining (S300) a first number of sensor nodes and their respective locations, out of said plurality of sensor nodes, to monitor the communications system in its entirety, based on measurements from at least some of the plurality of sensor nodes at their respective locations; determining (S310) a second number of said fog nodes and their respective location, based on the first number of sensor nodes and a connectivity capacity of said second number of fog nodes, where the second number of fog nodes is determined to cover said first number of sensor nodes; ranking (S320) said second number of fog nodes according to a conditional probability of failure for the second number of fog nodes, based on determined information about the second number of fog nodes and their respective location; and identifying (S330) a top ranked subset of said second number of fog nodes, based on said ranking (S320) of said second number of fog nodes; and positioning (S340) a backup fog node at each location of the top ranked subset of the second number of fog nodes.

An alert that is generated by a first orchestrator associated with a first subsystem or received from one or more distributed orchestrators that are associated with one or more corresponding subsystems is analyzed. The alert is triggered by a change in behavior determined by a behavioral analysis algorithm associated with the first orchestrator or corresponding behavior analysis algorithms associated with the one or more distributed orchestrators. It is determined whether an alert is indicative of a false positive based on an objective associated with the first orchestrator, an algorithm associated with the first orchestrator and one or more constraints associated with the first orchestrator. The alert is filtered in response to determining that the alert is indicative of the false positive.

A method for processing radio link failure (RLF) information includes obtaining sidelink (SL) RLF information of an SL on which an RLF occurs and a terminal device is in an idle state or an inactive state. The further includes determining that the terminal device is in a connected state, and sending the SL RLF information to a network device.

A traffic light determining apparatus, a system including the same, and a method thereof, includes: a processor configured to obtain traffic light status information of an intersection while a vehicle is driven, and when obtaining the traffic light status information is not possible, configured to estimate the traffic light status information according to surrounding vehicle information or pedestrian information; and a storage configured to store data and algorithms driven by the processor.

A system, includes a non-transitory memory; and one or more hardware processors coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to cause the system to perform operations comprising: transmitting a message from an application client to a service to request content from the service; ascertaining a failure of the service to provide the requested content; and in response to ascertaining the failure, applying data from the application client to an application in lieu of the requested content.

In one set of embodiments, a computer system can create a snapshot of a data set, where the snapshot includes a plurality of data blocks of the data set. The computer system can upload the snapshot to a cloud object storage platform of a cloud infrastructure, where the snapshot is uploaded as a plurality of log segments conforming to an object format of the cloud object storage platform, and where each log segment includes one or more data blocks in the plurality of data blocks, and a set of metadata comprising, for each of the one or more data blocks, an identifier of the data set, an identifier of the snapshot, and a logical block address (LBA) of the data block. The computer system can then communicate the set of metadata to a server component running in a cloud compute and block storage platform of the cloud infrastructure.

A data linkage system includes a data accumulation system that collects and accumulates data held by an information system; and a control service section that manages access information used by the data accumulation system to connect to the information system. The control service section asks the data accumulation system to test the connection to the information system by using the access information managed by the control service section.
