The Design And Implement Of A Embedded Linux Based Network Management Analyzer

With the rapid development of information-technique, the application scale of computer network is becoming bigger and bigger. Network management is the most important measure to ensure the fully utilization of all kind of network resource and the dependable running of the network. Network management platform is the essential part of network management system.First, the thesis expatiates the background and meaning of this thesis, the concept of network management, the network management's concept, history and function. It also describes SNMP (simple network management protocol), the practically industrial standard of network management. Then, the thesis designs the whole handheld network management analyzer. It put forward in-depth analysis on the application characteristics and equipments on network analyzer from two aspects, hardware platform, software platform. Finally, it use the industrial single board computer system according to the industrial PC104 standards with Intel X86 series processor as hardware platform and embedded Linux operating system as software platform. The whole project is modularized, they are network equipment monitor module, network flow analyze module, network equipment fault module, network remote equipment config module and network test assistant tools module. The whole design buleprint is brought forward in the end. As a kernel, the thesis detailedly discusses the specific implementation of the handheld network management analyzer based on embedded Linux system. The article presents the basic structure of hardware platform and the structure of software platform include the structure of embedded. Linux software platform, the customization of micro-kernel and the process of constructing a file system. The thesis discusses the work flow of function modules and the algorithm of function modules, and takes MIB-get function as example to illustrate the programming implementation method of function module. At the last, based on the analysis of handheld network management's structure, the development situation of embedded operation system and network management system, thesis concludes several aspects for deep research in future.
