Cabling and Configuring the GV Orbit Server to support

7 Redundancy
To make streaming more reliable over an IP network, the implementation of
SMPTE ST 2022
-
7 seamless protection switching depends on stream redundancy. This
protection scheme transmits two identical SMPTE ST 2110-20 packet streams over
physically separate network routes (shown as Red LAN / A Network and Blue LAN /
B Network in the figure below), so that if one network goes down, the second network
takes over. This process is seamless because switching between the streams is
instantaneous and does not impact content.
The following figure shows two GV Orbit Servers in a cluster configuration where
GV Orbit
Server A
and
GV Orbit Server B
provide failover protection for each other. See also
PREREQUISITES:
• At least two network switches must be used for this application. Contact Grass Valley
for more information about switch compatibility. See
Grass Valley Technical Support
on page 60. These switches must be configured to be used with SMPTE ST 2022
-
7. See
the fabric configuration documentation supplied with the switch. For example, at
minimum, subnets and IP address ranges must be set.
• The connected network must have a PTP grandmaster server clock on its domain.
