According to Audinate, IGMP Snooping is vital when: When lots of Dante Multicast flows are used. When Dante is mixed with other Multicast traffic.
Full Answer
Does Dante require a dedicated network infrastructure?
No. Does Dante require a dedicated network infrastructure? No. Does Dante require a IP multicast capable switch? Yes, but all Ethernet switches support multicast. Does Dante require any special network infrastructure? No. Does Dante require special switches? No. Does Dante work with Fiber Optic network cable? Yes.
What is the latency of a Dante network?
On a Dante network, latency is: Deterministic, set per device The default Dante latency of 1 millisecond is: Very low and suitable for the majority of applications How many channels can a gigabit connection handle of Dante audio at 48kHz sample rate and 24-bit depth?
What protocol does Dante use for QoS?
Dante devices each contain a very high quality VCXO clock, and are synchronized with one another over the network using the IEEE 1588 Precision Time Protocol (PTP). How does Dante manage QoS? Dante uses standard Voice over IP (VoIP) Quality of Service (QoS) switch features to prioritize clock sync and audio traffic over other network traffic.
How do switch hops affect Dante latency?
True. How do switch hops affect Dante latency? More switch hops -> greater minimum latency. Settings above the minimum are unaffected. Can a Dante network with 5 switch hops support latency of 1 ms or less? Yes. Minimum recommended latency will be 0,5ms. How can actual latency performance be seen? Using the Latency monitor in Dante Controller.
Does Dante use IGMP?
Dante supports both IGMP V2 and V3, but all switches in the network should be running the same version. So if the network includes switches which support only IGMP V2, be sure to select "IGMP V2" as the IGMP querier version.
What type of network connections should be used to transport Dante traffic?
No – Dante does not support Wi-Fi, your networked devices must all be physically connected to the Dante network via Ethernet Cat5e or Cat6 cables across a compatible network switch.
When choosing a network switch what minimum speed is suggested Dante?
While Gigabit switches are recommended, 100Mbps switches may be used in limited scenarios. For low channel count (<32) applications, a 100Mbps switch may be used as long as it supports proper QoS, and QoS is active.
When a Dante enabled device is plugged into a network How does Dante Controller discover it?
Dante devices discover one another on the network automatically. Each Dante device discovers the input and output audio channels, sample rates and bit depths of others on the network. Dante devices assign themselves IP addresses that are guaranteed to be unique and not conflict with other devices on the network.
Does Dante use multicast?
Dante multicast uses the 239.255/16 address range and port 4321. Most Dante devices also support sending and receiving RTP (SMPTE 2110-30 or AES67) multicast. RTP multicast usually uses port 5004.
What type of network service is Dante?
Dante is a combination of software, hardware, and network protocols that delivers uncompressed, multi-channel, low-latency digital audio over a standard Ethernet network using Layer 3 IP packets.
What switch should I use with Dante?
Dante makes use of standard Voice over IP (VoIP) protocols and utilises Quality of Service (QoS) switch features, to prioritize clock sync and audio traffic over other network traffic....Recommended Switch ExamplesCisco SG200 Series.Cisco SG300 Series.Cisco SG350 Series.
When would be a good time to consider engaging QoS?
QoS is required when using Dante in networks that have 100Mbps devices and is optional in networks with Gigabit devices. We recommend that QoS be enabled in all Dante networks in order to ensure proper operation under all possible conditions.
Is Dante a layer 2 or 3?
layer 3Because Dante uses the Internet Protocol to manage the way audio is moved around the network, it is referred to as a layer 3 solution.
How does Dante network work?
The Dante hardware or software in a device takes digital audio and 'packetizes' it. The audio is segmented and wrapped it in IP (Internet Protocol) packets suitable for transmission across a standard IP network.
How does Dante discovery work?
Dante Discovery is an Audinate service that Dante software uses on Windows platforms to discover Dante-enabled devices on the network. It is installed automatically with newer Dante software applications, and for those applications it takes over the role of the previously used discovery service, Apple Bonjour.
What is needed for a Dante network?
What are the minimum system requirements for Dante Virtual Soundcard? Network interface: Standard wired Ethernet, 100Mbps or higher. A Gigabit (1000Mbps) interface is necessary for use with channel counts above 32×32 @48kHz.
How to monitor Dante channels?
To monitor specific channels on a multi-channel Dante device, first Dante-enable your headphones or speakers (click the 'Enable Dante control for the headphones or speakers destination), and then use Dante Controller to send the required transmit channels from the Dante device to your headphones' receive channels.
What is Dante audio?
Dante is a combination of software, hardware, and network protocols that delivers uncompressed, multi-channel, low-latency digital audio over a standard Ethernet network using Layer 3 IP packets.
Does Dante always have a clock master?
No. A Clock Master is always automatically elected by Dante. Dante transmitters are sources. Dante receivers are: Destinations. The easiest way to get IP addresses for a functional stand-alone Dante network is for all devices and computers to: use the "obtain an IP Address Automatically" setting.
Does Dante require a managed switch?
If a network is only used for Dante and has only one network switch, then: The network does not require a managed switch.
Does Dante use MIDI?
No. Dante only transports audio data, and does not interfere with MIDI. The names of devices and channels in Dante are: User-definable and remembered by devices. The sample rate of an audio system dictates: The highest audio frequency that the system can handle. The bit depth of an audio system dictates:
How to configure IGMP Snooping?
When to Configure IGMP Snooping#N#IGMP Snooping is required when: 1 Multicast Dante or AES67 flows are in use. 2 Dante traffic is mixed with other Multicast traffic, such as Multicast video systems. 3 Critical control systems are on the same network as Dante devices, such as Crestron/AMX/Extron control devices. 4 Using Dante in 100M (Fast Ethernet) networks, as bandwidth is limited (we do not recommend using 100Mbps switches). 5 Using a Wi-Fi access point on the same network as Dante devices (Dante multicast data can flood the Wi-Fi, and therefore we generally do not recommend using Wi-Fi access points on Dante networks).
What is IGMP snooping?
IGMP Snooping helps prevent transmission of Multicast traffic to ports that don't need them. On larger, shared networks with Dante or AES67 multicast flows, IGMP Snooping greatly reduces the amount of Multicast traffic on the network by only forwarding Multicast data to the devices that request it.
What is Dante traffic?
Dante traffic is mixed with other Multicast traffic, such as Multicast video systems. Critical control systems are on the same network as Dante devices, such as Crestron/AMX/Extron control devices. Using Dante in 100M (Fast Ethernet) networks, as bandwidth is limited (we do not recommend using 100Mbps switches).
Do Igmp snoopers need a single switch?
Small, isolated networks with a single switch that have only Shure or other Dante-enabled devices generally do not require IGMP snooping, as the amount of Multicast generated will be very low (Multicast traffic is used only for clocking, discovery, and control in these cases—not audio).
Does Fast Leave harm Dante?
It may show IGMP Query messages from multiple sources. Contact Shure Applications Engineering for help interpreting Wireshark traces. Fast Leave will not har m a Dante network and is generally required for Multicast video traffic. Avoid IGMP proxies, unless you are CERTAIN you know how it behaves.
