Events (Messages) and Data
Since TANGO uses central server architecture, there are system scalability concerns.
System makes careful distinction between event and data distribution pathways
- events are always distributed via collaboratory server
- data may be distributed via collaboratory server for thin data streams
- voluminous data are either distributed directly between application instances or delivered from HTTP or other servers
- peer-to-peer application data exchange may use multicast if necessary
- certain TANGO applications are therefore implemented as Web browsers for specialized data types (e.g., GIS Open Inventor Web browser)
