Example 3: Routed Network Configuration
NOTE: It is immaterial, in this example, which codec is the encoder and which is the
decoder. These functions are not identified in figure 8.
Figure 8 shows an example of a routed network configuration. Codec 1 is configured as the
controller, via LAN port 2.
• The two codecs are connected across a wide area network (WAN) via an external router.
• Network 1, connected to LAN port 1 (RJ-45 port), the “green” network — This
network is separated from the streaming network. This is the primary network for
system control and monitoring.
• Network 2, connected to LAN port 2 (the fiber optic port), the “red” network —
The encoder streams video on this network and it can also used for system control and
monitoring if desired.
NOTE: Selection of this network for streaming is via the built-in HTML network
interface. This selection is defined in the management interface, described
later (see “Configure Encoders or Decoders“).
• The gateway IP addresses (the addresses on both sides of the router on the red network)
is set on LAN port 2 (configuration option 14) for both codecs.
• This architecture provides isolation between the video transport and simple network
management protocol (SNMP) traffic.
NOTE: The SNMP protocol includes a system of SNMP trap messages. SNMP trap
messages can be initiated by a network element and sent to the network
management system.
