PRIMARY MASTER
The first EtherSound device in the network is called the Primary Master. As well as being a source of audio
for the network, the Primary Master provides the commands and the clock for audio channel synchronization.
The Primary Master may also serve as the link between the EtherSound network and configuration software
running on an external computer, connected to its Ethernet IN/FROM port.
SLAVE
An EtherSound device that receives the EtherSound stream and restores standard audio is called a Slave.
A slave answers to the status requests and commands of the Primary Master.
STAR
Star is a network topology where all devices are connected to a same unit (a switch in the following picture)
that is handling all the communications.

SWITCH
Device to connect two segments of a Local Area Network. Seeking greater filtering and forwarding speeds,
efforts were made to decrease the amount of time required to determine whether a packet should be filtered or
forwarded ('latency') by only examining the address information contained at the start of the Ethernet frame.
The term 'Ethernet Switch' now is used for multiple-port-devices, which are able to filter and forward packets
at nearly the speed of Ethernet ('wire speed') regardless of the technique.
