Abstract: A cloud server acquires a stop period indicating a period during which a management server refrains from providing services; transmits connection requests to said management server if not in the stop period; establishes first communication session when establishment requests including the same address information as address information of connection destination included in the connection request are received from a relay device receiving connection requests forwarded from the management server after transmission of connection requests; transmits jobs to a control target device via first communication session; after first communication session is established, in response to acquisition of result of jobs executed by the control target device, if in the stop period, disconnects first communication session after the stop period finished; and if jobs are generated in the stop period, transmits to the control target device jobs generated in the stop period, via first communication session established before the stop period starts.

Abstract: A communication system includes a plurality of communication relay apparatuses relaying communication between the plurality of devices provided inside a LAN and an external server provided outside the LAN. A first communication relay apparatus performs a device search process of searching the LAN for a device, acquires information on a first management target device which is a device whose communication relay process is managed by a second communication relay apparatus, and determines a second management target device which is a device whose communication relay process is managed by the first communication relay apparatus. The first communication relay apparatus determines the second management target device after removing at least partial duplication of the second management target device and the first management target device, by excluding at least some of the first management target device from two or more devices which are retrieved in the device search process.
