Abstract: A node (100) includes a detection unit (122), an identification unit (123), and a determination unit (124). A detection unit (122) detects occurrence of a failure in a controller to which telemetry information in a slice is notified. An identification unit (123) identifies telemetry requirements of the slice when the detection unit (122) detects occurrence of the failure. A determination unit (124) determines whether to notify an alternative controller of the telemetry information in the slice in accordance with the telemetry requirements identified by the identification unit (123).

Abstract: An orchestrator locates a server in anyone of a plurality of edge clouds on the basis of a plurality of delay differences, respectively corresponding to the plurality of the edge clouds having each delay difference and assumed if the server located in each of the edge clouds, that are each a difference between delay from the server to a first client and delay from the server to a second client, and gives a delay to at least one of the first client and the second client so that the delay from the located server to the first client and the delay from the located server to the second client become the same.
