A system, method and recording medium for managing ONU using management agent in passive optical network

PURPOSE: A system and a method for managing local units using management agent in an Ethernet-PON(Passive Optical Network) and a recording medium thereof are provided to allow an operator to accurately recognize and effectively manage an operation state of a local unit. CONSTITUTION: A network management protocol communicating unit(212) converts a network management protocol message received from an Ethernet-PON manager system into an IPC message and transmits it to each function managing unit. A configuration managing unit(214) manages state information of a node, a module, a board and a port constituting each element. A performance managing unit(215) collects performance information of various types of ports of a host unit and local units. A failure managing unit(216) manages failure of a fan or a power supply unit as well as failure of the board or the port of each element. A local unit communicating unit(217) performs function of transferring operation management information of a local unit managed in a detailed management function and function of transferring an operation command requested by the detailed management function from the host unit to the local unit. A local unit operation managing unit(231) processes the operation command of the network manager system transferred from the local unit communicating unit(217), and transfers the performing result and an event generated from the local unit to the host unit.
