A network fault management system research is discussed in the environment of Broadband Community Netw ork (EBCN)based on Ethernet .The fault management system based on event flow model and algorithms, which the fault detection takes integration of two type events, including performance polling and trap receiving .After analysis for the event flow model, the merger of events and faults are presented according the fault status and problems of the network .The fault management structure is applied to enhance the fault management simply and practically on algorithms and solutions.
