Embodiment Construction

[0020] The method process of the present invention is as Figure 4 shown, where:

[0021] 1) Adopt no-refresh technology, such as figure 1 shown. In AJAX, JavaScript is mainly used to transfer the data on the user interface to the server and return the result. The XML Http Request object is used to respond to the data delivered through HTTP. Once the data is returned to the client, the DOM can be used to immediately put the data on the web.

[0022] 2) When drawing node information, such as figure 2 As shown, first judge the resolution of the computer, if the resolution width is less than 1280, then obtain r=min(resolution width / 3, resolution height / 3) (r is the distance between the initial node and the center point); if the resolution If width>=1280, then r=min (wide resolution / 2.8, high resolution / 2.8) is obtained.

[0023] 3) Then judge whether to partition, if the number of nodes > 64, then display the partition, calculate the coordinates and draw the node topology; ...

Abstract

The invention discloses a method for realizing dynamic topology. The method is used for realizing a corresponding topology structure change on the basis of a number change in a topological graph. According to the method, a no-refresh technology is adopted, the problem, which is caused by the addition or reduction of child nodes, about the real-time display of the topological graph can be solved, and the topological graph is dynamically displayed by comprehensively taking the resolution of a computer into account and calculating the coordinates of topological nodes. The topologic graph is specified according to the amount of equipment, a neighborhood relationship is acquired through connecting lines, a physical connection relationship between the equipment in a network is accurately reflected, and a logical hierarchical relationship is reflected to a certain extent. A changed network topological graph can be generated in real time, the automatic layout of the network topology is realized, and the definition of the topological structure of the network is improved; and the method is adapted to the topological display of a dynamic network.

Description

technical field [0001] The invention relates to a method for realizing dynamic topology, which is a method for realizing the change of corresponding dynamic topology structure after the number of devices changes. Background technique [0002] According to the definition of the OSI open system interconnection model, network management mainly includes five functional domains: fault management, configuration management, performance management, security management and billing management. [0003] Among the five functional domains, configuration management is the foundation, and its main functions include discovering the topology of the network, monitoring and managing the configuration of network devices. [0004] The goal of network topology management is to display the topological structure of the operating network hierarchically, provide support for the processing of performance, alarm, and configuration data, thereby comprehensively and dynamically reflect the operation of t...
