Management method and system for separation type gateway as well as computer equipment

The invention discloses a management method and system for a separation type gateway as well as computer equipment. The management method comprises steps as follows: communication connection is established between PON equipment and gateway equipment on the basis of a G.hn technology; on the basis of the communication connection, the PON equipment receives identification parameters sent by the gateway equipment, wherein the identification parameters comprise physical addresses and user identification and are taken as equipment parameters; the PON equipment sends the equipment parameters to an optical line terminal to finish registration authentication; the gateway equipment sends the equipment parameters to a terminal integrated management system; the gateway equipment receives business work orders which are sent by the terminal integrated management system on the basis of the equipment parameters and correspond to the equipment parameters, and an unvarnished transmission pathway is established between the PON
