NDI Network Layout

NDI is designed for use with standard consumer off-the-shelf (COTS) networking devices. Looking closely at the network topology and configuration will help to ensure the maximum possible bandwidth is available.

When selecting a network switch, it is important to check the throughput speeds. Ensure that each port is full duplex (i.e. bi-directional communication) and that the upstream and downstream data speeds for each port are at least 1 Gigabit per second (Gbps). It is best to force the ports on managed switches to utilize 1 Gbps in contrast with Auto Negotiation. The use of Auto Negotiation can sometimes result in 100Mb connections or even lower, which does not renegotiate until the port is flooded with traffic for some time. Also, poor termination of RJ-45 connectors can impact Auto Negotiation.


When possible, it is best to use switches from the same manufacturer, or ideally, the same model of switch, throughout a single subnet. This will simplify configuration and lessen the chances of compatibility and configuration issues.
