Abstract
Systems and methods include receiving first power snapshot from a receiving end of a foreign controlled link of the one or more foreign controlled optical links when there are no faults thereon; responsive to obtaining second power snapshot from the receiving end of the foreign controlled link, detecting a fault on one of at least one channel and part of the spectrum traversing the foreign controlled link; correlating the second power snapshot with the first power snapshots; and raising an indication of fault for the foreign controlled link based on the correlating.
Claims14
A method of controlling one or more foreign controlled optical links comprising:
- receiving a first power snapshot from a receiving end of a foreign controlled link of the one or more foreign controlled optical links when there are no faults thereon;
- receiving a second power snapshot from the receiving end of the foreign controlled link;
- correlating the second power snapshot with the first power snapshot;
- and
- raising an indication of fault for one of at least one channel and part of the spectrum traversing the foreign controlled link based on the correlating.
An apparatus comprising:
- a processor and memory storing instructions that, when executed, cause the processor to
- receive a first power snapshot from a receiving end of a foreign controlled link of the one or more foreign controlled optical links when there are no faults thereon,
- receive a second power snapshot from the receiving end of the foreign controlled link,
- correlate the second power snapshot with the first power snapshot;
- and
- raise an indication of fault for one of at least one channel and part of the spectrum traversing the foreign controlled link based on the correlating.
A non-transitory computer-readable storage medium having computer readable code stored thereon for programming a device to perform steps of:
- receiving a first power snapshot from a receiving end of a foreign controlled link of the one or more foreign controlled optical links when there are no faults thereon;
- receiving a second power snapshot from the receiving end of the foreign controlled link;
- correlating the second power snapshot with the first power snapshot;
- and
- raising an indication of fault for one of at least one channel and part of the spectrum traversing the foreign controlled link based on the correlating.
