3.3.3 Network Redundancy
The MV-805 offers support for network redundancy, ensuring protection of an IP pathway
from a multicast IP stream’s source to the MV-805’s destination spigot via second network
(Fabric B), see Figure 4. Thus there are two identical Multicast IP streams available.
The receiving destination spigots use both IP streams to re-form the original IP stream, using
the first data packet to arrive from fabrics “A” or “B”.
3.3.4 IP Streams and Flows
IP streams are IGMPv3 multicast IP streams.
IP streams may consist of sub-streams, or “flows” (see Figure 5). There are three media IP
flows:
•
Video flow - carries video image essence.
•
Audio flow - carries audio essence.
•
Metadata flow.
