Abstract: Method, system and apparatus are provided for transmitting data over a network based on external, non-network oriented (external to the network) stimulus. A facility's physical security, environment monitoring/management, or production control system utilizing a frame-based/packet-based network includes a number of edge devices, an event/state change detector, a priority, security level, route specification, destination changer, a transmitter, and a number of destination devices. Edge devices generate data for the network; the event/state change detector identifies an event associated with the data; the priority, security level, route specification, destination changer changes the priority, security level, route, destination of the data, based on the detected event or state change; and the transmitter then transmits the data to an intended destination device, based on the changed priority, security level, route, and destination.
