Abstract: Disclosed is a method for generating a multi-protocol fault management (FM) packet by using a field-programmable gate array, including: setting information related to FM in a plurality of local maintenance entity group end points (LMEPs); performing a polling process of the plurality of LMEPs according to the packet types after obtaining send instructions related to a certain packet type; determining a protocol type of the plurality of LMEPs; obtaining information related to the protocol type; acquiring information related to the packet type under the protocol type; generating a corresponding number of FM packets in accordance with the information related to the protocol type and the at least one set of field information related to the packet types; and outputting the FM packets. The method enables transmission of CCM, LCK and AIS packets under ETH, ITU and IETF packets to be achieved. Therefore, compatibility and competitiveness of products are improved.
