SWITCHFEATURESDANTE CERTIFICATION PROGRAMLEVEL 211

MANAGED VS. UNMANAGEDManagedUnmanagedMore expensive Many possible settings(and risks) May be required in someconditionsLess expensive 100% plug and play May not be appropriate insome situations Audinate Pty Ltd. All rights reserved12

THEN YOU DON’TNEED A MANAGEDSWITCHIf you use only one switch to connect your Dante devices If you are only using the network for Dante audio 13

SWITCH FEATURES RECOMMENDATIONSStart with the default features Do not change settings until there is a problem that the featuremay help Resist temptation to over-configure! In most stand-alone Dante networks, features are not required Incorrect switch configurations are a common cause of problems Audinate Pty Ltd. All rights reserved14

CLOCKINGDANTE CERTIFICATION PROGRAMLEVEL 215

HOW DOES DANTE CLOCKING WORK?Dante handles clockingautomatically via election IEEE1588 PTP All devices sync'd to Master Each device has a clock New Clock Master electedas neededCLOCKMASTER Audinate Pty Ltd. All rights reserved16

CLOCK MASTERSClock Master determined byelection in accordance withIEEE1588 Rig Election with “PreferredMaster” and “Enable Sync toExternal” settings Understanding the electionprocess Audinate Pty Ltd. All rights reserved17

ADJUSTING CLOCKSClock Status tab inDante Controller Checkboxes for PreferredMaster and Enable Sync toExternal Audinate Pty Ltd. All rights reserved18

WINCLOCK ELECTIONPreferred MasterEnable Sync toExternalNothing checked Audinate Pty Ltd. All rights reserved19

PREFERRED MASTERDante will always elect a Clock Masterwithout intervention Changes to Clock Master are automaticand do not affect audio Any hardware device can be made a“Preferred Master” clock Preferred Master should be a device thatis always present in system Audinate Pty Ltd. All rights reserved20

USING EXTERNAL CLOCKS“Enable Sync to External” allowsuse of console (or other) clock Configure in console, too Check “Preferred Master” Mismatch may result in pops andclicks Using Active Clock Monitoring toensure quality of external clock Audinate Pty Ltd. All rights reserved21

EXTERNAL CLOCK BEST PRACTICESIf using an external clock, configure inboth device and Dante Controller (EnableSync to External) Always check Preferred Master on thedevice using Enable Sync to External Symptom: clicks and pops Audinate Pty Ltd. All rights reserved22

CLOCK STATUS MONITORINGPassive: always on Clock Master changes onlyActive: select in toolbarto turn on Useful for troubleshootingexternal clocks Looks for instability Accumulates data over time Displays spread of clockfrequency Audinate Pty Ltd. All rights reserved23

LATENCYDANTE CERTIFICATION PROGRAMLEVEL 224

ABOUT LATENCY – A REFRESHERAudio signal delay in a system Transport and processing Mainly a problem when we hear delayed andun-delayed signal simultaneously Air travel 34cm 1msec Problem for legacy networking systems (VoIP) Audinate Pty Ltd. All rights reserved25

SETTING AND MONITORING LATENCYDouble click any device inrouting view to open the DeviceView Set latency in DeviceConfig tab Monitor latency in Latency tab Audinate Pty Ltd. All rights reserved26

LATENCY IN DANTE 100% deterministic – alwayswell-defined Default Dante latency 1ms –suitable for large networks Adjustable to suit needs– Minimum 150μs– Maximum 5ms Set per Device Audinate Pty Ltd. All rights reserved27

LATENCY - LOWER BOUNDS If only 1 switch, Dante latency canbe set to 150μs 3 switches, 250μs 10 switches, 1ms (Dante default) Recommended values are basedupon worst-case scenarios Monitor actual networkperformance Audinate Pty Ltd. All rights reserved28

MONITORING LATENCY – GOOD EXAMPLE Visualize actual latency in LatencyTab of Device View Example:– 3 switches– 1ms latency setting All packets safely inside window Try lower values and see whathappens Audinate Pty Ltd. All rights reserved29

MONITORING LATENCY – BAD EXAMPLEExample: 250μs latency setting Some packets are dangerously close tothe edge of the windowSolutions: Increase latency Improve network performance (QoS, etc.) Replace faulty equipment Disable unneeded switch management Audinate Pty Ltd. All rights reserved30

FLOWSAND MULTICASTDANTE CERTIFICATION PROGRAMLEVEL 231

UNICAST AND MULTICASTUnicastOne to one traffic “Private conversation” – datasent uniquely from transmitterto each receiver Multiple receivers requiremultiple copies of data fromtransmitterMulticast(unmanaged)One to many traffic “Public announcement” –messages sent to everybodyon the network Data is processed by allreceivers Audinate Pty Ltd. All rights reserved32

UNICAST AND MULTICASTUnicastMulticast1 data stream per receiver1 data stream for all receivers Audinate Pty Ltd. All rights reserved33

DIFFERENCES:BROADCAST AND MULTICASTIf unmanaged, both send data out of all members of a LAN Multicast traffic can be organized to send data only torequesters (receivers) – IGMP snooping Organization of multicast receiving groups is done withmanaged switch Separate LANs or VLANs used to manage both types Audinate Pty Ltd. All rights reserved34

DANTE UNICAST FLOWSDante packages audio into 4channel “Flows” when usingunicast, for efficiency1 Flow to 1 Receiver containing 1 channel of audioAFlow 1 AudioB(empty)C(empty)D(empty) Flows are unique to each receiver1 Flow to 1 Receiver containing 4 channels of audioAFlow 2 AudioBAudioCAudioDAudio Flows may contain empty audiochannels 1 channel sent to 1 receiver usesthe same bandwidth as 4channels Audinate Pty Ltd. All rights reserved35

DANTE UNICAST FLOWSMore receivers means more Flows More channels (4 at a time, 1 receiver)means more Flows Small Dante devices (1 to 4 channels)support 2 Flows Large Dante devices (16 channels andup) support 32 Flows Audinate Pty Ltd. All rights reserved36

DANTE AND UNICAST FLOWSNAF8 channels each - 2 flows each - 4flowsTUO8 channels each - 2 flows each - 8 flows Audinate Pty Ltd. All rights reserved37

DANTE AND MULTICAST FLOWSMulticast solves “fan out”condition Up to 8 audio channels in 1multicast flow Configured in Dante Controller8 channels - 1 multicast flow Audinate Pty Ltd. All rights reserved38

CONFIGURING MULTICAST FLOWSOpen Device View Click “Create Multicast Flow” buttonin toolbar Choose up to 8 channels for a singlemulticast flow You may create more multicast flowsif needed Audinate Pty Ltd. All rights reserved39

DO I NEED TO CONTROL MULTICAST?On gigabit networks, multicast traffic is unlikely to bea problem Example: 64 channels of multicast produces approximately100mbits/sec of traffic If using 100mbps devices or Wi-Fi access on the samenetwork, use multicast filter (IGMP Snooping) Use multicast selectively! Audinate Pty Ltd. All rights reserved40

SUMMARYDante uses unicast by default Dante audio is packaged into multi-channel flows Number of flows is limited (between 2 and 32) Each receiver requires at least 1 flow Unmanaged multicast sends data to all devices Multicast is useful for conserving flows in one-to-many situations Explicit management of multicast often not necessary Audinate Pty Ltd.
