Abstract: A method of streaming data elements from an industrial site to a remote server, including: receiving data elements from industrial devices on the industrial site, storing the data elements in a queue, periodically extracting a number N of data elements from the queue and aggregating the same into one data frame whose size does not exceed a maximum size, storing each data frame in a buffer, and periodically extracting a data frame from the buffer and sending the same to the remote server. A data element is removed from the queue and stored in a database if the data element's time in the queue exceeds a maximum queuing time. A data frame is stored in the database instead of being stored in the buffer if the buffer is full. The maximum queuing time is optimised as a function of the latest number of data elements removed from the queue and the frequency at which the buffer is full.
