Network setup
A Tracking Server takes in camera tracking data, processes it and forwards it to the render engine. The Tracking Server is run on the same machine as the engine.
For best stability make the tracking data use its own network.
Typically one tracking system sends data via unicast to one or more specific engines. If data is needed by more engines use multicast to distribute tracking. Use broadcast addresses only if multicast is unavailable, but be aware that this can quickly flood the network.
