Patent ID: 7961737

Claim:
A method for transmitting an Operation Administration and Maintenance frame in an Ethernet/Transport Multi-Protocol Label Switch hybrid network, comprising: receiving a first Ethernet Operation Administration and Maintenance frame (Ethernet OAM frame) by a node; mapping values in an Ethernet Operation Administration and Maintenance data field in a protocol data unit (PDU) in the first Ethernet OAM frame into a Transport Multi-Protocol Label Switch Operation Administration and Maintenance data field (TMPLS OAM data field) in a PDU in a first Transport Multi-Protocol Label Switch Operation Administration and Maintenance frame (TMPLS OAM frame) by the node; mapping values in first control parameter fields in the first Ethernet OAM frame into second control parameter fields in the first TMPLS OAM frame by the node, wherein the PDU in the first TMPLS OAM frame comprises an added extra Transport Multi-Protocol Label Switch Operation Administration and Maintenance field (extra TMPLS OAM field) and wherein the second control parameter fields further comprise preselected default information and routing information mapped from values stored in a memory; wherein first control parameter fields in the first Ethernet OAM frame comprise a destination address field and a source address field; and wherein value in the destination address field is mapped into a part of the extra TMPLS OAM field and value in the source address field is mapped into another part of the extra TMPLS OAM field; and transmitting the first TMPLS OAM frame by the node.
