The source host can model the prediction algorithm being used by the remote
host.
The host only needs to transmit updates when there is a significant divergence
between the object’s actual position and the remote host’s predicted
position.
Only transmit an update when an error threshold is reached or after a timeout
period (heartbeat).
Entities must have a “heartbeat” otherwise cannot distinguish
between live entities and ones that have left the system.
