Abstract
A method for creating an Operation Administration and Maintenance frame in an Ethernet/Transport Multi-Protocol Label Switch hybrid network. The method includes mapping values in an Ethernet Operation Administration and Maintenance data field in a protocol data unit (PDU) in a first Ethernet Operation Administration and Maintenance frame (Ethernet OAM frame) into a Transport Multi-Protocol Label Switch Operation Administration and Maintenance data field in PDU in a first Transport Multi-Protocol Label Switch Operation Administration and Maintenance frame (TMPLS OAM frame) and mapping values in first control parameter fields in the first Ethernet OAM frame into second control parameter fields in the first TMPLS OAM frame. The PDU in the first TMPLS OAM frame includes added extra fields as necessary, and the second control parameter fields further comprise preselected default information and routing information mapped from values stored in a memory.
