However, automatic negotiation will be carried out at sending and receiving ends when establishing connections,
which ensures delay time is negotiated to prevent packet loss.
For example, Ultimo devices support minimum 1ms delay. If the delay for a faster device like a PCIe card is set at
0.25s and the device is establishing connection with an Ultimo device, then the delay of subscription will be 1ms
which is the minimum delay supported by subscriptions. If minimum delay possibly reaches 1s in a megabyte
network, then a subscription error may occur when transmitting based on the condition that delay time is no more
than 1s.
Network Configuration:
Network configuration refers to network IP address, mask, and gateway settings. Brooklyn supports redundancy
mode and exchange mode settings.
Redundancy Mode
Many Dante devices have two network ports named “Primary” and “Secondary. “Primary port connects the
physical network. If “Secondary” port has been used, then “Secondary” port shall connect to another physical
network. The “Secondary” port cannot communicate with the “Primary” port.
Multicast Stream:
What is stream? Dante audio routing automatically creates streams. A stream moves audio data of several channels
from transmitter ends to one or more receiving ends. Unicast streams are given to single receiving devices while
multicast streams are given to multiple receiving devices. Multicast streams may be created or configured manually
through the interface, but it uses network bandwidth whether there is receiving device or not. Meanwhile, it
doesn’t need extra bandwidth when more receiving ends are added.
As shown in the figure, select the multicast stream label page, check device channel, click create, and then created
multicast stream will display in the right list of the interface. It can also be deleted when users dont need it. A
stream mostly include s four channels by default. If more than four channels are checked, they will be divided to
several streams automatically.
