With the continuous strengthening of competition in China’s telecommunications market, the technology and management of the telecommunications industry have made great strides forward. If the system application, server or network equipment fails and there is no suitable solution, it will have a great impact on the whole business activities of the enterprise. Modern network is no longer simply providing an end-to-end service as reliable as possible, but is committed to providing users with high-quality and reliable communication service quality to meet the bandwidth delay requirements of various applications. The networking of monitoring system is one of the main goals of monitoring system development, which develops with the wide application of information technology represented by Internet. In order to improve the level of operation and maintenance, customer satisfaction and market competitiveness, enterprises undoubtedly need to speed up the construction of integrated network management system. This paper discusses the method of combining genetic algorithm and computer network technology to realize computer telecommunication network management and centralized monitoring, which is of great significance to improve the level of field maintenance and management.
