A ring topology may be used in order provide redundancy and thus increase reliability. This topology is to be
considered an extension of the daisy chain topology, where the last device is physically connected to the first
one. The priority "Preferred Primary Master" is defined by the network dministrator through the of
EtherSound control software.
Preferred
Primary Master
•
In case of a cable malfunction, the first device following this failure is then automatically designated
"Primary Master". The network remains entirely functional, it there no audio signal loss.
•
In case of a device malfunction, the same recovery mechanism applies, but - obviously - the audio
connected to the defective device will be missing.
STAR
The Star is a network topology where all devices are connected to a same unit (a switch in the following
picture) that handles all communications. A star topology is able to transmit easily and efficiently the
EtherSound channels towards a great number of destinations. However, it has to be kept in mind that in this
case, the stream of audio data is mono-directional (from the "Primary Master" towards the other devices).
