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.

Claims

1. A method for data transmission over a network, the method comprising

generating data for the network, the data being generated by an edge device;

detecting at least one of an event and a state change associated with the data;

changing one or more parameters associated with the data based on the detected event or the state change; and

transmitting the data to a destination device based on the changed parameters.

2. The method of claim 1 where the one or more parameters associated with the data is selected from a group consisting of a priority, a security level, a route, and a destination of the data.

3. The method of claim 1 wherein the generated data is an audio stream.

4. The method of claim 3 wherein the event associated with the audio stream is a varied resolution and/or frame rate of the audio stream.

5. The method of claim 1 wherein the generated data is a video stream.

6. The method of claim 5 wherein the event associated with the video stream is a varied resolution and/or frame rate of the video stream.

7. The method of claim 2 wherein the one or more parameter associated with the data is changed by changing at least one of:

the layer-2 priority bit(s) settings of the data and the layer 2 encapsulation of the data payload based on security coding and attributes of the payload identified in layer 2 of a given protocol.

8. The method of claim 2 wherein the one or more parameter associated with the data is changed by changing at least one of:

the layer-3 priority bit(s) settings of the data as defined by an Open Standards Interconnection reference model, and the layer 3 encapsulation of the data payload based on security coding and attributes of the payload identified in layer 3 of a given protocol.

9. A method for changing one or more parameters associated with a media stream, the method comprising

generating a media stream for the network, the media stream being placed in the form of a payload field(s) in a frame or a packet;

detecting an event or state change associated with the media stream; and

changing the parameters of the media stream based on the detected event or state change.

10. The method of claim 9 wherein the one or more parameters associated with the media stream is selected from a group consisting of a priority, a security level, a route, and a destination of the media stream.

11. The method of claim 9 wherein the media stream is an audio stream.

12. The method of claim 11 wherein the event associated with the audio stream is a varied resolution and/or frame rate of the audio stream

13. The method of claim 9 wherein the media stream is a video stream.

14. The method of claim 13 wherein the event associated with the video stream is a varied resolution and/or frame rate of the video stream.

15. The method of claim 10 wherein the parameter associated with the media stream is changed by changing at least one of:

the layer-2 priority bit(s) settings of the media stream and the layer 2 encapsulation of the media stream payload based on security coding and attributes of the payload identified in layer 2 of a given protocol.

16. The method of claim 10 wherein the parameters associated with the media stream is changed by changing at least one of:

the layer-3 priority bit(s) settings of the media stream and the layer 3 encapsulation of the media stream payload based on security coding and attributes of the payload identified in layer 3 of a given protocol.

17. A system for data transmission over a network based upon a non-network event or stimulus, the system comprising

means for generating data for the network, the data being generated by an edge device;

means for detecting at least one of an event and a state change associated with the data;

means for changing at least one of a priority, a security level, a route, and a destination of the data based on the detected event or the state change; and

means for transmitting the data to a destination device based on the changed priority.

18. The system of claim 17 wherein the generated data is an audio stream.

19. The system of claim 17 wherein the generated data is a video stream.

20. A system for data transmission over the network comprising

at least one edge device for generating data for the network;

an event/state change detector for detecting an event or state change associated with the data;

a priority, security level, route, and/or destination changer for changing a priority, security level, route, and/or destination of the data based on the detected event or state change; and

a transmitter for transmitting the data to a destination device over the network based on the changed priority, security level, route, and/or destination.

21. The system of claim 20 wherein the generated data is an audio stream.

22. The system of claim 20 wherein the generated data is a video stream.

23. The system of claim 22 wherein the event/state change detector detects the event on the basis of a varied resolution of the video stream.

24. The system of claim 20 wherein the event/state change detector detects the event on the basis of a variance in the frame rate of the data.

25. The system of claim 20 wherein the edge device is selected from a group comprising a video recorder, an audio recorder, a fire alarm, a smoke alarm, air quality monitor, chemical composition monitor, a badge reader, and an event or state change sensor or device connected to the facility'"'"'s physical security, environment monitoring or management system.

29. The system of claim 20 wherein said system comprises a facility'"'"'s physical security, environment monitoring/management or production control system for data transmission over the network.

27. An apparatus for data transmission over a network, the apparatus comprising

a processing system including a processor coupled with or independent of a display and a user input device;

a machine-readable medium including instructions executable by the processor comprising

one or more instructions for generating data for the network, the data being generated by an edge device;
