NDI is designed to enable successful video transport using the default configurations of network interface drivers, however most recent network interface drivers do support configuration of advanced properties that can help optimize NDI transmission.
Consider the following adjustments, but note that making adjustments on individual adapters can significantly affect performance and reliability; both positively and negatively. It is important to consider testing performance with a network analyzer before and after each setting change. The following adjustments are intended to help, however performance will depend on particular network and usage (names and available settings vary between vendors, adapter models, and even between different driver versions):
Speed and Duplex: This setting allows for selection of the desired speed and duplex of the network adapter. Usually this is set to Auto Negotiation. To ensure the maximum available throughput, this setting should be set to 1 Gbps Full Duplex.
Energy Efficient Ethernet: When enabled, this allows the adapter to engage power saving features while keeping connections active. This technology uses the standard IEEE 802.3az to allow for less power during periods of low data activity. Adapters that utilize the IEEE 802.3az standard should have no impact on performance of NDI, however some integrated circuits exist that were developed before the standard was finalized or do not adhere to the standard at all. In these cases, it is best to disable the energy efficiency while determining best network optimization.
