A standard IMP is fitted with a 10Gbe network card (with 10Gbe port). Many streaming aspects of the Igloo (NDI, Dante, other streaming protocols) can be quite bandwidth-intensive, so a 10Gbe switch is best placed to help ensure the smoothest streaming playback.
Optimal performance is achieved when AV streaming is on a separate VLAN - best practice is to have separate VLANs for NDI devices, a separate VLAN for control systems, and a separate VLAN for Dante (if required)
Some peripherals in an Igloo System utilise the Power over Ethernet standard and, recently with the edition of some 4K NDI PTZ webcams, this can include a requirement for PoE++ network switches.

An Igloo system may depend on much more than basic web traffic, so it is important to take into consideration the type of traffic that will be in common use and how it will impact your network. A simple playback system will not generate much traffic outside of Windows Updates and downloading new content; in this regard the server will behave similarly to a typical client. When content streaming is a requirement, there are some bandwidth and latency requirements to keep in mind, and a network administrator should be involved to make sure there are no adverse effects on your corporate network.
Some protocols such as those used by NDI or Dante devices can be quite noisy in terms of traffic generation, and use up considerable bandwidth on the network. In cases where these devices are placed topologically far away from the Igloo server on a client network, we would recommend implementing traffic segregation e.g. VLANs. This requires L3 capable devices to route traffic correctly to the Igloo server, as well as Multicast routing in order for the mDNS traffic to cross subnet boundaries. A solution such as this would be discussed as part of a network integration consultation.
NDI
NDI is a fairly efficient protocol for streaming high quality video content over a network. This is bandwidth intensive by nature, however; a single NDI stream of a 1080i video source will take up around 100Mbps, and requires a latency of around 14ms to avoid frame dropping; 4k at 60fps can burst up to 350Mbps. It is important to consider how many NDI streams you may have active at a time, and how they are going to traverse your network. It is generally best practice to have clients that need to send NDI streams to the Igloo media server on the local Igloo network, as this reduces the round-trip-time, and also reduces traffic flow across your corporate network.
