Abstract


In recent years , as we are gradually entering the Internet age , it is increasing dependence on information networks . Network testing is to ensure network performance, high reliability and high availability of the basic means of . Network Tester as one of the most important tools in network testing , its importance is increasingly a cause for concern . This paper describes the basic architecture of the network , including the significance of the network hierarchy , and each layer corresponds to a specific protocol . And describes the concept as well as the significance of the network monitoring , network monitoring some of the most important standards and protocols , including MIB, SNMP, RMON brief introduction . Network tester also related to network topology discovery , the article also explains the theoretical basis of the network topology discovery and use more network topology discovery algorithm . The middle part of the article discusses the design of the entire portable network tester . Network Tester application features and design requirements , respectively, from the three aspects of the hardware platform , software platform , and graphical user interface support system -depth demonstration and analysis of selected program . The entire system uses a modular design approach , respectively Ping module , host module , network path search module , network equipment monitoring module , network packet analysis module and network topology discovery module gives the overall architecture of the system design . As the focus of the paper discusses in detail the implementation method based on MiniGUI portable network tester . The first describes the basic architecture of the hardware platform , and then for the system software platform , composed of embedded Linux software platform , micro-kernel customization , and the establishment of the file system details . Then describes the structure of the graphical user interface support system , including the realization of the principle of the of MiniGUI server process and the client process . Elaborated upper functional modules workflow details of the algorithm used by the topology discovery module and module implementations described Ping module , for example . Finally , in the analysis of the structure and performance of the system on the basis of the deficiencies of the existing system improvements, and made ??some comments and recommendations on the follow-up development work .
