Central server is the main communication element.
-
Local daemons communicate with the central server.
-
Server maintains the system state data
-
Sever routes messages between applications participating in each session and records all events in the back-end database.
-
Currently, TANGO system is restricted to only one collaboratory server.
-
We are investigating a model for inter-server communication. This research is directed towards extended functionality of a collaboratory systems such as automatic discovery of potential collaborators.
