Network management simulation system and method of optical transmission system

The invention discloses a network management simulation system and method of an optical transmission system. The method comprises the following steps: collecting an optical transmission system parameter to generate a network topological structure; according to input simulation setting information, regenerating a new network topological structure; according to an input cross-configuration simulation order, carrying out cross-linking on an appointed network element; according to the corresponding relationship of a cross script and a single deck, analyzing a cross error; and finally outputting service configuration analysis data. In the invention, the whole physical optical fiber transmission network is simulated and real network management configuration and operation are simulated on an analog transmission network by simulating a network management interface, a network topological structure, a data configuration, a menu, an operation mode and the like which are the same as those of the real optical fiber transmission network management, thus obtaining a result and fining problems as early as possibly, avoiding disruptive influence of the misoperation on the practical optical fiber transmission network on various electricity generation services.
