System and method for end-to-end beaconing

1. A method comprising:

generating a beacon command directing an addressed device to activate a light generating device physically located at and associated with a receipt port receiving the beacon command of the addressed device, the receipt port capable of performing normal network data transfer communications, the light generating device emitting light that is visible to a user; and

transmitting, from a transmitting port capable of performing normal network data transfer communications, the beacon command to the addressed device, wherein

the beacon command comprises at least a first field including a blink frequency value indicating a frequency at which to blink the light generating device.

2. The method of claim 1 , further comprising:

receiving, at the transmitting port, an acceptance reply from the addressed device, the acceptance reply indicating that the beacon command is accepted by the addressed device; and

in response to receiving the acceptance reply, activating a light generating device physically located at and associated with the transmitting port, the light generating device emitting light that is visible to a user.

3. The method of claim 1 , wherein the beacon command is further configured to cause activation of a light generating device physically located at and associated with a receipt port receiving the beacon command and a light generating device physically located at and associated with a transmitting port transmitting the beacon command, each light generating device emitting light that is visible to a user, at one or more other devices that receive and forward the beacon command toward the addressed device.

4. The method of claim 1 , wherein the beacon command comprises a second field including a request type specifying activation of the light generating device.

5. The method of claim 4 , wherein the beacon command comprises a third field including a duration value indicating a time duration to activate the light generating device.

6. A system comprising:

a processor;

a transmitting port coupled to the processor, for coupling to an addressed device and capable of performing normal network data transfer communications; and

a memory coupled to the processor and including instructions executable by the processor, wherein the instructions cause the processor to

generate a beacon command directing the addressed device to activate a light generating device physically located at and associated with a receipt port receiving the beacon command of the addressed device, the receipt port capable of performing normal network data transfer communications, the light generating device emitting light that is visible to a user; and

issue the beacon command from the transmitting port to the addressed device, wherein

the beacon command includes a plurality of fields comprising one or more of: a blink frequency indicating a frequency at which to blink a light generating device physically located at and associated with a receipt port receiving the beacon command of the addressed device; and a blink duration indicating a time duration for which to keep a light generating device physically located at and associated with a receipt port receiving the beacon command of the addressed device activated.

7. The system of claim 6 , wherein the beacon command is further configured to cause activation of a light generating device physically located at and associated with a receipt port receiving the beacon command and a light generating device physically located at and associated with a transmitting port transmitting the beacon command, each light generating device emitting light that is visible to a user, at one or more other devices that receive and forward the beacon command toward the addressed device.

8. The system of claim 6 , wherein the transmitting port includes a light generating device physically located at and associated with the transmitting port, the light generating device emitting light that is visible to a user,

wherein the transmitting port receives an acceptance reply accepting the beacon command from the addressed device, and

wherein the memory further includes instructions which cause the processor, in response to receiving, at the transmitting port, the acceptance reply to activate the light generating device physically located at and associated with the transmitting port.

9. The method of claim 1 , wherein the blink frequency value indicates a number of blinks during a predetermined time interval.

10. The method of claim 9 , wherein the predetermined time interval is 10 seconds.

11. The method of claim 1 , wherein the beacon command comprises a second field including a duration value indicating a time duration to activate the light generating device.

12. The system of claim 6 , wherein the blink frequency value indicates a number of blinks during a predetermined time interval.

13. The system of claim 12 , wherein the predetermined time interval is 10 seconds.

14. An electronic device comprising:

circuitry; and

a transmitting port coupled to the circuitry, for coupling to an addressed device and capable of performing network data transfer communications, wherein

the circuitry is configured to

generate a beacon command directing the addressed device to activate a light generating device physically located at and associated with a receipt port receiving the beacon command of the addressed device, wherein the beacon command includes at least a first field including a blink frequency value indicating a frequency at which to blink the light generating device and a second field including a blink duration value indicating a time duration for which to keep the light generating device activated; and

control the transmitting port to transmit the beacon command to the addressed device.

15. The electronic device of claim 14 , wherein the blink frequency value indicates a number of blinks during a predetermined time interval.

16. The electronic device of claim 15 , wherein the predetermined time interval is 10 seconds.

17. The electronic device of claim 14 , wherein the beacon command includes a third field including a request type specifying activation of the light generating device.
