Basically, it depends on neighborliness. Data can be injected from any point on the Internet where an LDM system has been installed. Data subscription . Users of IDD can select from the available data only those they need. Local processing .
Users can update their data files or conduct their own processing of selected data.
User-defined tables contain the criteria for selecting data and for controlling which data are routed to what files and processed. Reliable data delivery . Reliable transport protocols ensure the accuracy of data arriving at a site. A queuing system buffers data flows at relays, preventing losses from network congestion and short outages. Eventually IDD will automatically switch to a backup system during severe outages.
