IDENTIFYING FAULT LOCATIONS IN A NETWORK
First Claim
1. A method for identifying a fault location in an optical network comprising:
- monitoring, by a network element, an eastward optical path for faults;
monitoring, by the network element, a westward optical path for faults;
transmitting, by the network element, a first data packet along the eastward path, the first data packet comprising;
a first eastward fault indicator comprising information associated with any eastward faults occurring on the eastward path, the first eastward fault indicator indicating the existence of an eastward fault and the network element that detected the eastward fault; and
a first westward fault indicator comprising information associated with any westward faults occurring on the westward path, the first westward fault indicator indicating the existence of a westward fault and the network element that detected the westward fault; and
the method further comprising transmitting, by the network element, a second data packet along the westward path, the second data packet comprising;
a second eastward fault indicator comprising information associated with any eastward faults occurring on the eastward path, the second eastward fault indicator indicating the existence of an eastward fault and the network element that detected the eastward fault; and
a second westward fault indicator comprising information associated with any westward faults occurring on the westward path, the second westward fault indicator indicating the existence of a westward fault and the network element that detected the westward fault.

Abstract
Systems and methods for identifying a fault location in an optical network are disclosed. In accordance with one embodiment of the present disclosure, a method for identifying a fault location in an optical network comprises monitoring, by a network element, an eastward optical path and a westward optical path for faults. The method further comprises transmitting, by the network element, a first data packet along the eastward path and a second data packet along the westward path. The first and second data packets comprise an eastward fault indicator and a westward fault indicator comprising information associated with any eastward or westward faults occurring on the eastward or westward paths. The fault indicators indicate the existence of an eastward or westward fault and the network element that detected the fault.

8. A network element comprising:
-
a controller configured to; monitor an eastward optical path for faults; monitor a westward optical path for faults; and generate a first data packet and a second data packet, the first data packet comprising; a first eastward fault indicator comprising information associated with any eastward faults occurring on the eastward path, the first eastward fault indicator indicating the existence of an eastward fault and the network element that detected the eastward fault; and a first westward fault indicator comprising information associated with any westward faults occurring on the westward path, the first westward fault indicator indicating the existence of a westward fault and the network element that detected the westward fault; the second data packet comprising; a second eastward fault indicator comprising information associated with any eastward faults occurring on the eastward path, the second eastward fault indicator indicating the existence of an eastward fault and the network element that detected the eastward fault; and a second westward fault indicator comprising information associated with any westward faults occurring on the westward path, the second westward fault indicator indicating the existence of a westward fault and the network element that detected the westward fault; the network element further comprising one or more interfaces communicatively coupled to the controller and configured to transmit the first data packet along the eastward optical path and transmit the second data packet along the westward optical path as directed by the controller. - View Dependent Claims (9, 10, 11, 12, 13, 14)
