Networking and Dante

Digital Audio Networking

Dantetm 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)

Dante™ Transmit Flows

Dante Flows

This device supports up to two transmit flows and two receive flows. A single flow consists of up to four channels, through either a unicast or multicast

transmission.

•

A unicast flow is a point-to-point connection between two devices, supporting up to four channels per flow.

•

A multicast flow is a one-to-many transmission, which supports sending up to four channels to multiple receiving devices across the network.

Shure Device Applications

This device can connect with up to two Dante devices.

The Shure MXA310, ANI22, ANIUSB-MATRIX and ANI4IN support multicast transmission. This means that flows can transmit to multiple devices -- as many

as the network can support. If using unicast flows, each of these devices can connect with up to two Dante receiver devices.

The Shure ANI4OUT connects with up to two Dante transmitter devices.

QoS (Quality of Service) Settings

QoS 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.
