Design And Implementation Of A Visualization System Of Information For Network Topology And Real-time Traffic

Network topology visualization is an important analysis tool for monitoring network status.The network topology visualization system can dynamically display the data traffic and network communications in the monitoring system in a perceptible and interactive way,assisting managers in monitoring and network situation analysis,and comprehensively improving the network monitoring and management capabilities.However,the existing network monitoring methods and software display use static and flat non-intuitive topology display forms,which are relatively backward and cannot correctly feedback the logical and physical relationships between nodes at the same time and cannot feedback the multiple contact forms between nodes that can't keep up with the rapid development.This subject focuses on analyzing,designing and implementing a visualization system of network topology and traffic monitoring.Using three-dimensional visualization information system and network topology,direct feedback of the dynamic information flow in the network topology in the time dimension and space dimension,supporting network managers to quickly grasp the network situation and make correct decisions.This thesis takes the software engineering development process as the standard and discusses a way in the network topology to visualize data such as traffic,equipment,resources and performance.First,analyze and research the network topology visualization platform to obtain user portraits and functional requirements;then clarify the system outline design,architecture design,and functional module division and design;perform detailed design of the system,draw class diagrams and timing diagrams of each functional module,design a front-end architecture which contains the visualization layer and the panel layer.And use the modern webpage architecture that separates the webpage end and the data server end to encode it.Finally,perform functional tests on the system to verify the correctness of the system,and perform non-functional tests such as performance tests on the system to ensure that the system meets the quality requirements.This thesis implements a highly scalable topology network visualization scheme based on modern web technology.The system is connected to the network management and monitoring systems of cooperative laboratory for visualization service.
