Abstract
Provided is a method and system for switching between signals in an optical transport network. The method includes extracting identification data from an OTN signal at a termination sink and inserting the identification data into an Ethernet packet. The system includes a termination sink configured to extract identification data from an OTN signal and insert the identification data into an Ethernet packet.
Claims16
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.
A system for monitoring a working OTN signal in an optical transport network (OTN) network element (NE), the system comprising:
- a termination sink within the NE, the termination sink having identification data;
- and
- a termination source within the NE, the termination source having identification data and being in communication with the termination sink;
- the termination sink configured to:
- receive the working OTN signal;
- obtain 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;
- insert the performance monitoring results into a payload portion of an Ethernet packet;
- insert identification data of the termination sink into a source address portion of the Ethernet packet;
- insert identification data of the termination source into a destination address portion of the Ethernet packet;
- and
- send the Ethernet packet to the termination source.
