EtherSound tested switches
The evaluation of the switches is mainly focused on the performance, and particularly on:

the jitter induced by the switch (for all the switches).
the ability to handle correctly different VLANs containing identical MAC addresses, as ES devices have 2 Ethernet ports with a unique MAC address (managed switches)
