Data from a source device to a data requester

Abstract:

It is provided a method for providing device data from a source device to a data requester. The method is performed in a data provider and comprises the steps of: determining operating mode being either a pass-through mode or a cache mode, based on estimated resource usage for each of the pass-through mode and the cache mode; receiving a read request from the data requester; when the data provider is in the pass-through mode, transmitting a corresponding read request to the source device and forwarding a read response from the source device to the data requester; when the data provider is in the cache mode, retrieving device data from storage of the data provider and transmitting a read response to the data requester, the read response comprising the device data from storage; and populating the storage of the data provider with device data received from the source device.
