REDUNDANT MODE
There are
two simultaneous network connections
(each with its own IP address, both
different) so that the information Ethernet packets Dante
™
are transmitted via both
connections.
Each port (primary and secondary) must be connected to a different physical Ethernet local
network, or to a different virtual local network (VLAN), correctly configured and isolated
from each other.
The digital audio Dante
™
is therefore sent and received using two distinct and
independent paths
, with no possible communication between the primary and
secondary ports.
In case one of them fails, VIDA will automatically switch to the other
,
recovering the audio transmission almost instantaneously. Obviously, to achieve total
redundancy, all Dante
™
devices that are part of a system of this type must have primary
and secondary Dante
™
ports, connected respectively to the same two independent
networks as VIDA.
In this mode, if (by mistake) the primary and secondary ports connect to the same
Ethernet network, Dante
™
Controller will no longer have access to the network
configuration control and routing Dante
™
of the VIDA ports. This control is recovered
when one of them is disconnected from the same network as the other.
Dante
™
redundancy requires that the primary and secondary ports of all Dante
™
devices connect using the same network connection speed
. For example, if the primary
port connects to a network with a 1 Gbps link, the secondary port must also connect at 1
Gbps.
