RAVENNA Streaming: a User's View
While the OSI reference model provides a technician's view of RAVENNA technology, this can be simplified into
the following end-user's view:
Layer 1 is the Audio Transport which is handled by the data network.
Layer 2 is the Virtual Patching which is handled in the background by the Zone Controller.
Layer 3 is the Signal Handling . In mc
2
/Nova73 systems, this is performed from the console or mxGUI via the
Signal List display. In crystal and sapphire/Nova17, signal routing is usually defined by the zirkon configuration.
Layer 4 represents any automated or scripted applications which, in turn, control each of the lower layers.
Examples of application in this layer are VisConNavigator and a VSM control system.
