A method and system for checking and optimizing single point fault of electric power communication service

The invention discloses a method for checking and optimizing a single point fault of an electric power communication service. The method comprises the steps of establishing a physical link model of acommunication network; analyzing the total amount of service information, and establishing the service set to be checked; obtaining the service logical channel routing information according to the service information to be sorted out, obtaining the service physical channel routing information, and searching for a single point of hidden trouble; reconstructing the logical link model of communication network, adding optical path resource occupancy ratio information, marking the physical link co-routing situation in the logical link, and establishing the logical link co-routing set; and routing optimization of a single point of failure is carried out. The method of the invention has the advantages that the hidden trouble of the single node is quickly identified and found, and the optimizationsuggestion of the optimal
