Abstract


With the popularity of computer applications , network size in growing a network monitoring system for network administrators to master the topology of the entire network , quickly and positioning network failures are a major help . This paper first introduces the technical background of this paper , including the introduction of network management knowledge , the SNMP the composition and characteristics of the QT development libraries , the characteristics of the signals and slots . These are the follow - up work of the foundation. Then the paper in accordance with the software engineering workflow data analysis subsystem needs analysis and overall design , data analysis the subsystem module functional requirements , as well as performance , reliability and scalability, and other non- functional requirements in the requirements analysis described . The design principles and system overall framework of the overall design of the system and system modules , described the scene . Described in the fourth chapter the analysis module design and implementation of state , state analysis module the topological state handling , processing and physical state of the physical state of storage and query . This section complete package handling SNMP-based link layer topology discovery and network status . Chapter clarifies event analysis module design and implementation of event analysis module is based on a defined set of events , according to the analysis the resolved topology status and real-time access to network physical state , generates the state of events in the state collection , and realize the event storage and query capabilities . In the sixth chapter illustrates the design and realization of the packet analysis module . The packet analysis is the analysis of unpacking the data packets based on the predetermined data for the protocol packet format , and returns the packet Matching . By looking for the same packet of data packets from each terminal to crawl and analysis functions of the packet path is performed based on the time of the data packet generation . Design and Implementation of the system is completed , the paper described the test of the system and test cases test results are recorded in a summary table of test cases . Finally, a summary of this article and of the results of the work in the subject during , and made the the papers next step in the direction of work .
