Apparatus and method for controlling devices in requested resource via network

An apparatus connected via a communication network, with a plurality of controllable devices which are associated with a resource,

• the apparatus operating for controlling the devices, in combination with:
• a registry storage for storing information of device configurations and device identifiers for identifying the respective devices;
• and
• a repository storage for storing a correspondence between the device identifiers and device controllers which match the respective devices, and which are executed to control the respective devices, by calling a common interface which is shared between the device controllers,
• the apparatus comprising:
• a resource-request receiver configured to receive a resource request including information for identifying a requested resource which is requested to be controlled, and information for identifying a requested size of the requested resource which is requested to be reached;
• a service manager configured to retrieve from the registry storage, at least one of the device identifiers which corresponds to at least one designated device, as at least one designated device-identifier, wherein the at least one designated device is at least one of the plurality of devices which is associated with the requested resource of the received resource-request;
• a repository retriever configured to retrieve from the repository storage, one of the device controllers which corresponds to the retrieved designated device-identifier, and to install the retrieved device controller into a library;
• and
• a control manager configured to call the common interface of the designated device controller installed in the library, to thereby execute the designated device controller, in order to control the requested resource on the designated device to reach the requested size, and, after completion of the control of the designated device, to uninstall the called device controller from the library.
