Snmp-based Ftth Nms Design And Implementation

With the fast information process of our society, more and more kinds of new business spring out in the Internet, which makes the need of access network bandwidth keep increasing. Although the much fast ADSL and ethic network are replacing the way of dialing, these technology can not solve the bottle neck problem of the last mile. However, the FTTH(fiber to the home) satisfy the people's need of network bandwidth. The system of network management is used to monitor, control and harmonize all the administrable objects. With the development of network technology, the number of hosts in network is becoming bigger, the distribution of network is becoming more wider and the structure of network is becoming more complicated. The devices and hosts of network are supplied by different manufacturers, which results in many kinds of systems and protocols exist in the network. The limits of persons for the network system maintenance work make daily maintenance difficult. So the management of network becomes very important. At present, the SNMP(simple network management protocol) is one protocol used widely and realized easily, which has been supported by many manufacturers and became the actual standardization protocol in the network management of the industry. The network management system in the paper is used to realize the management of topology, performance, fault of the FTTH network. In this paper, the market background of FTTH network, the model and conception of OAN (optical access network), the standard and function requirement of network management, and the actuality of FTTH network management are introduced at the first. After introducing the constitution, communication model, the management model and the solution of the FTTH access network, the paper provides the system analysis, summary design, detail design and realization of the FTTH network management system based on SNMP.
