ETHERNET/TMPLS HYBRID NETWORK OPERATION ADMINISTRATION AND MAINTENANCE FRAME CREATION METHOD

摘要

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 (445) in a protocol data unit (PDU 410) in a first Ethernet Operation Administration and Maintenance frame (Ethernet OAM frame 150) into a Transport Multi-Protocol Label Switch Operation Administration and Maintenance data field (498) in PDU (460) in a first Transport Multi-Protocol Label Switch Operation Administration and Maintenance frame (TMPLS OAM frame 155) and mapping values in first control parameter fields (401) in 'the first Ethernet OAM frame (150) into second control parameter fields (402) in the first TMPLS OAM frame (155). The PDU (460) in the first TMPLS OAM frame (155) includes added extra fields (495) as necessary, and the second control parameter fields (402) further comprise pre-selected default information and routing information mapped from values stored in a memory.
