Method and system for generating network quality reference library, and central server

The invention discloses a method and system for generating a network quality reference library and a central server, and the method comprises the steps: obtaining a specified number of standard network lines, determining the linear distance between the starting position and the ending position of each standard network line, and recognizing the transmission path length of each standard network line; determining an actual physical transmission factor based on the transmission path length, and determining an actual optical length factor based on the optical fiber length in the standard network line; and determining quality parameters of the standard network lines according to the linear distance, the actual optical length factor, the actual physical transmission factor and a preset loss coefficient, and generating a reference library for detecting the network quality based on the quality parameters of the standard network lines. According to the technical scheme provided by the invention, a standard quality eval
