In this paper, a mathematical model for information communication is constructed, and a genetic algorithm is introduced for model optimization. Experimental results show that the genetic algorithm effectively enhances network reliability and significantly reduces link costs. In the application experiments, this model can analyze the advantages of different optimization paths and select the optimal solution based on actual conditions, ensuring both network reliability and economy, and increasing overall satisfaction with the network
