Telecommunication network management is accompanied by the development of the telecommunications network size, capacity and technical sophistication of the equipment and gradually developed. In recent years, rapid communication network networking technology, expanding the network, the network's complexity and flexibility greatly enhanced, the urgent need to build strong, efficient, multi-vendor environment to adapt to the communication network in order to ensure efficient communication networks, high quality, safe and stable operation. The goal is to build a comprehensive network management system in the existing basis, the establishment of multi-disciplinary information centralized control of integrated network management platform, the customer data and network resources in an effective device associated constructed network service management, establish and improve the Webmaster control as the core maintenance system, the formation of forward-facing, business-Response Center as the leading rapid response mechanism to focus on improving the operation of market-oriented network management system, to achieve high-quality, high reliability, high efficiency, low cost of maintenance goals. CAS is a telecommunications underlying support integrated network management system, which stands for Common Agent System. Due to the current telecommunications equipment, model range, the large number of widely distributed on the different types of access network elements, data collection, analysis, processing, both very different to the daily operation and maintenance of the telecommunications sector has brought many difficulties. The purpose of this subsystem design CAS is to resolve these differences, on the flexible interface to provide uniform services to facilitate business systems on the upper NE data processing, to improve the efficiency of daily operation and maintenance. Chapter gives an overview: This article discusses the local fixed-line telecommunications industry in integrated network management system project background, domestic and international situation and the problems faced by its development and design, based on the analysis of the system requirements, the system requirements are described. Chapter UNIX interprocess communication: study of the UNIX interprocess access technologies, describes the CAS in the course of the process of communication technology used. Chapter III CAS system needs analysis: and the system needs analysis. On the CAS were introduced, the CAS must be completed to determine the function, while identifying the user's operating environment for CAS made complete, accurate, clear and specific requirements. Chapter CAS system design: architectural design carried out on the CAS. First, according to the system requirements of the system design goals and principles, and the overall structure of the system has been designed, given the overall structure of CAS, and analyzes the function of each part of the system components. Accordance with the structure of the part of the framework to design the system, and the design of each module are described, shows the relationships between the various modules. In this part of the process of the final details of the external and internal interfaces between modules process. Chapter CAS system detailed design: each module are discussed in detail design, and presents the design goals of each module, program listings, flow charts, and functions of the main variables described. Chapter VI Integrated Network Management System Outlook: In this paper, the application of integrated network management system and shortcomings are analyzed, and suggestions to further improve the system.
