| In telecom network and computer network,3G modem is a kind of widely usedphysical equipment. Compared with other equipments such as router in the networkmanagement,3G modem is a management object which has simple function, with thepopularization of3G network at the same time, it’s used widely. The reliability of3Gmodem in the network directly affects the performance of the network high-level protocoland the safety of the entire network. Therefore, strengthening the monitoring of3Gmodem, controlling timely the state of3G modem and locating error of3G modem, isvery important for the reliable operation of the3G network. The configurationmanagement of3G modem is an indispensable part of network management.With H3C company’s Modem development project as the background, achieving aconfiguration management system based on Linux platform, the system can be used as aindependent functional module of router software system. Based on a practical projectapplication, the distributed implementation, LIPC process communication message formatand DBM storage are studied deeply. System uses a structured oriented softwaredevelopment process, first of all introduces requirement analysis of the system, includingfunction requirements, reliability and maintainability requirements. Subsequentlyintroduces design and implementation of the system in detail, firstly gives the design ofthe whole system interaction and the design of system interact with the external functionmodule, secondly from the angle of releasing a system, achieves the decomposition andimplementation of a system, including command line plug-in module, the DLL module,cellular daemon module and core management module. Finally from the angle of the unittest and system test, introduces the test of3G modem configuration management system.The system runs on the router of H3C company steadily, through the actual operationverifys that the system design scheme meets the system requirements, achieving therequirements of practical application software. |
