Abstract

A network diagnostic system may include a network diagnostic device. The network diagnostic device may be configured to receive data indicating a light level of an optical signal and to perform at least one network diagnostic function at least partially in response to the receipt of the data. A network diagnostic method may include detecting a light level of an optical signal; and performing at least one network diagnostic function at least partially in response to the detection of the light level of the optical signal. Exemplary network diagnostic functions may include triggering an alarm; triggering a capture of at least a portion of one or more network messages; storing data indicating the light level of the optical signal on a computer readable medium (e.g., for use in subsequent reports); and/or any other suitable network diagnostic function.

Claims

1. A network diagnostic system comprising:

a network diagnostic device configured to receive first data indicating a light level of an optical signal and to perform at least one network diagnostic function at least partially in response to the receipt of the first data.

2. The network diagnostic system as in claim 1, wherein the at least one network diagnostic function comprises triggering an alarm.

3. The network diagnostic system as in claim 1, wherein the at least one network diagnostic function comprises triggering a capture of at least a portion of a network message.

4. The network diagnostic system as in claim 1, wherein the at least one network diagnostic function comprises triggering a capture of at least a portion of each of a plurality of a network messages.

5. The network diagnostic system as in claim 1, wherein the at least one network diagnostic function comprises storing second data indicating the light level of the optical signal on a computer readable medium.

6. The network diagnostic system as in claim 1, wherein the at least one network diagnostic function comprises storing second data indicating the light level of the optical signal in a database.

7. The network diagnostic system as in claim 1, wherein the light level of the optical signal comprises a light level of an optical signal received by a node of a network.

8. The network diagnostic system as in claim 1, wherein the light level of the optical signal comprises a light level of an optical signal received by a receiver of a node of a network.

9. The network diagnostic system as in claim 1, wherein the light level of the optical signal comprises a light level of an optical signal received by a switch.

10. The network diagnostic system as in claim 1, wherein the light level of the optical signal comprises a light level of an optical signal received by a physical layer switch.

11. The network diagnostic system as in claim 1, wherein the light level of the optical signal comprises a light level of an optical signal received by a first switch from a second switch.

12. The network diagnostic system as in claim 1, wherein the light level of the optical signal comprises a light level of an optical signal received from a passive tap.

13. A network diagnostic method comprising:

detecting a light level of an optical signal; and

performing at least one network diagnostic function at least partially in response to the detection of the light level of the optical signal.

14. The network diagnostic method as in claim 13, wherein the at least one network diagnostic function comprises triggering an alarm.

15. The network diagnostic method as in claim 13, wherein the at least one network diagnostic function comprises triggering a capture of at least a portion of a network message.

16. The network diagnostic method as in claim 13, wherein the at least one network diagnostic function comprises triggering a capture of at least a portion of each of a plurality of a network messages.

17. The network diagnostic method as in claim 13, wherein the at least one network diagnostic function comprises storing data indicating the light level of the optical signal on a computer readable medium.

18. The network diagnostic method as in claim 13, wherein the at least one network diagnostic function comprises storing data indicating the light level of the optical signal in a database.

19. The network diagnostic method as in claim 13, wherein the light level of the optical signal comprises a light level of an optical signal received by a node of a network.

20. The network diagnostic method as in claim 13, wherein the light level of the optical signal comprises a light level of an optical signal received by a receiver of a node of a network.

21. The network diagnostic method as in claim 13, wherein the light level of the optical signal comprises a light level of an optical signal received by a switch.

22. The network diagnostic method as in claim 13, wherein the light level of the optical signal comprises a light level of an optical signal received by a physical layer switch.

23. The network diagnostic method as in claim 13, wherein the light level of the optical signal comprises a light level of an optical signal received by a first switch from a second switch.

24. The network diagnostic method as in claim 13, wherein the light level of the optical signal comprises a light level of an optical signal received from a passive tap.
