NDI 在具有高頻寬的專用網絡中，能最有效率的運行。 儘管可以在快速乙太網路（100 Mbps）網絡上輕鬆交付單個 HD高清視訊即時串流，但還是建議乙太網路至少 1GB（1000 Mbps）以上為佳。 由於 HD 1080i 高清視訊組成的典型 NDI 即時串流，每個即時串流的每秒資料流量數據高達 100 Mbps。而 UHD 2160P 超高清視訊組成的典型 NDI 即時串流，每個即時串流的每秒資料流量數據高達 250 Mbps。 這種高效率的即時串流具有極低的延遲，並允許將多個即時串流堆疊到一個 1GB 網絡上。
NDI operates most efficiently in a dedicated network with high bandwidth and high availability. This is in contrast to unmanaged environments such as the public Internet or networks where video rides along with data without priority.
While a single stream of HD video can easily be delivered on a Fast Ethernet (100 Mbps) network, Gigabit (1000 Mbps) networks are essential in production workflows. A typical NDI stream consisting of 1080i HD video yields a data rate up to 100 Mbps per stream. This extremely efficient stream is designed to have very low latency and allows multiple streams to be stacked together on a single Gigabit network.
