Claim Text:
1. A method of monitoring a working OTN signal in an optical transport network (OTN) network element (NE), the method comprising: receiving the working OTN signal at a termination sink within the NE; obtaining performance monitoring results from the working OTN signal at the termination sink in the NE, the performance monitoring results including at least one of a backward defect indication (BDI), a backward error indication (BEI), a backward incoming alignment error (BIAE), and a summary of detected alarms and defects based on at least one of the BDIs and the BEIs detected at the termination sink over a period of time; inserting the performance monitoring results into a payload portion of an Ethernet packet; inserting identification data of the termination sink into a source address portion of the Ethernet packet; inserting identification data of a termination source corresponding to the termination sink into a destination address portion of the Ethernet packet; and sending the Ethernet packet to the termination source in the NE.
