Routing Dante Channels
Use the free Dante Controller software by Audinate to route Dante channels in and out of the MXCW system.
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.
Dante QoS Priority Values
Priority
Usage
Time-critical PTP
High (4)
events
Medium (3)
Audio, PTP
Low (2)
(reserved)
None (1)
Other traffic
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 Network Audio Encryption
Audio is encrypted with the Advanced Encryption Standard (AES-256), as specified by the US Government National Institute of
Standards and Technology (NIST) publication FIPS-197.
