Research And Design Of SNMP-based Network Management System For Optical Termination

The network is being a Multi-vendor Hybrid Network with The building of large-scale interconnection and the application of the rapid development of new technology and the wider use of new equipment. Network types, the type of services and equipment for the source of more complicated. Under such circumstances, extent and distribution of resources greatly enhanced sharing of any minor fault may lead to the failure of user applications. How early detection of the fault and the exclusion of potential hidden effectively manage networks, network equipment and network service providers issues of common concern. Facts have proved that good management of a network and network building are equally important.SNMP (Simple Network Management Protocol) is SNMP, mainly used to manage network devices, it is precisely because 'simple', its rapid development, and so far almost all of its network products to provide support to facilitate administrator management and the development of software developers. Microsoft WinSNMP SNMP protocol for the development of application programming interfaces,are a group of services for the construction of SNMP, SNMP management agent and expansion of the library system, which defines the procedure call, data structure and related syntax. Overall WinSNMP to function in the form of the SNMP package of the various parts of the agreement, embodied in the windows operating system and winsnmp.lib winsnmp.dll for,and against the use of SNMP UDP transmission characteristics set up a news Retransmission, overtime mechanism can be set up under the news network needs to re-transmission frequency and the transmission of overtime hours.The first half of this paper focused on the concept of network management, basic network management model, SNMP and SNMP versions - SNMPv1, SNMPv2 and SNMPv3, Windows SNMP system development process, WinSNMP the use of application programming interfaces. Elaborate on the latter part of the fiber optic transmission equipment NMS features, design and implementation. In the system design of the system described in various parts of the functions of the system to achieve some of the various functional modules, a method focused on the serial and Ethernet Network Management compatibility, dynamic MIB issue.
