Abstract: Disclosed herein are optical networks and nodes, including a head-end node comprising a controller and a line module. The line module comprises a first processor and first memory storing instructions that when executed by the first processor cause the first processor to receive fault information, generate a fault packet and a fault trigger request that include a sequence number, a sequence reset time, and the fault information, and send the fault packet via a first network path and the fault trigger request via a second network path to the controller. The controller comprises a second processor, second memory storing second instructions, and packet forwarding circuitry configured to receive and automatically forward the fault packet to a tail-end optical node. The second instructions cause the second processor to receive the fault trigger request, process the fault trigger request, and send the fault trigger request to the tail end optical node.
