[Abstract]:With the development of computer network, both the network scale and the type of equipment have grown to a large order of magnitude, and the network structure has changed at all times, which greatly increases the difficulty of understanding and understanding the network. How to show the dynamic network topology accurately, clearly and intuitively is an important research topic in the field of network. At the same time, the network topology diagram which adapts to the change of network structure is helpful to understand the existing network. This paper focuses on the design and implementation of the network structure in the up and down line changes as well as changes in the number of the effective use of the last layout results to quickly redraw the network topology diagram and maintain the maximum stability of the network topology diagram. Firstly, the network topology discovery algorithm and the classical network topology layout algorithm are deeply studied and analyzed. The topology discovery algorithm based on SNMP and the topology layout algorithm based on FR are analyzed in detail. The application range, advantages and disadvantages of the algorithm are summarized, and the problems of force-oriented algorithm in the dynamic change of the network are emphatically analyzed. Secondly, aiming at the dynamic change of network structure, that is, mapping to topology graph when adding or decreasing nodes, the current algorithm can not adapt to the change and redraw topology graph quickly and stably, based on FR algorithm model. A dynamic automatic layout algorithm of network topology is designed and implemented. The topology structure of dynamic network is displayed and compared with FR algorithm. The experiments show that the proposed algorithm has better fast and stable characteristics. Finally, based on the topology layout algorithm mentioned above, a real-time monitoring system for on-line network equipment is designed and implemented. The overall framework and main functions of the system are given, and the system is tested and verified. The test results show that, This algorithm can accurately detect the online state of network devices, maintain the stability of topology graph and display the network topology more quickly and clearly.
