The invention discloses a multipurpose avionics relay network topology configuration management method and a multipurpose avionics relay network topology configuration management system, wherein the method includes the following steps: the configuration information of all network device fibre-optic links in a network is transmitted by a server; after receiving the configuration information, each network device obtains respective configuration information of the fibre-optic link, obtains and transmits the identity information of the opposite devices and the port number information of the connected opposite devices to the server at the same time, and then transmits the configuration information of all the network device fibre-optic links to the other network devices. By means of the invention, network authentication can be conveniently carried out, consequently, the consistency between actual network topological relation and an expected network topology structure can be guaranteed or the difference between the actual network topological relation and the expected network topology structure can be known and adjusted. Because the configuration of the network topology can be directly viewed and edited, the configuration of the network topology can be efficiently managed.
