Foil 22 Events and Data

From TANGO Interactive Training NPAC Training -- Dec 11 and 12 1997. by Marek Podgorny


1 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 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)
