Dante & Networking
Digital Audio Networking
Dante
tm
digital audio is carried over standard Ethernet and operates using standard Internet Protocols. Dante provides low latency, tight clock synchronization,
and high Quality-of-Service (QoS) to provide reliable audio transport to a variety of Dante devices. Dante audio can coexist safely on the same network as IT
and control data, or can be configured to use a dedicated network.
Switch Recommendations for Dante Networking
In addition to the basic networking requirements, Dante audio networks should use a Gigabit network switch or router with the following features:
• Gigabit ports
• Quality of Service (QoS) with 4 queues
• Diffserv (DSCP) QoS, with strict priority
• Recommended: A managed switch to provide detailed information about the operation of each network link (port speed, error counters, bandwidth used)
QoS (Quality of Service) Settings
QoS settings assign priorities to specific data packets on the network, ensuring reliable audio delivery on larger networks with heavy traffic. This feature is
available on most managed network switches. Although not required, assigning QoS settings is recommended.
Note:
Coordinate changes with the network administrator to avoid disrupting service.
To assign QoS values, open the switch interface and use the following table to assign Dante™ -associated queue values.
• Assign the highest possible value (shown as 4 in this example) for time-critical PTP events
• Use descending priority values for each remaining packet.

Note:
Switch management may vary by manufacturer and switch type. Consult the manufacturer's product guide for specific configuration details.

Networking Terminology
PTP (Precision Time Protocol): Used to synchronize clocks on the network
DSCP (Differentiated Services Code Point):
Standardized identification method for data used in layer 3 QoS prioritization
Dante™ Transmit Flows
For each device, there is a limit of
two transmit flows
and
two receive flows
. A single flow consists of up to
four channels
, through either a unicast or multicast
transmission.
