Problems solved by technology

When the force-guided layout algorithm calculates the internal force between nodes, it does not follow Hu Ke's law, but establishes a set of repulsion-gravity system by itself. In this way, it is necessary to calculate the force between every two points until the dynamic balance, resulting in time high complexity

Abstract

The present invention provides a network topology visualization method with respect to geographical location information, comprising: S1: performing pre-process of input data; S2: performing geographic area partitioning of the network topology data; S3: performing topology partitioning; S4: performing topology layout; and S5: performing output of real and complex network topology location information data and realizing visualization. According to the invention, the aesthetic property is not be changed in the case of increasing the geographical location information of the nodes, the location ranges of important nodes are more clear through the improved round layout algorithm, and the round layout may be not influenced by the connection relation of the nodes at the boundary and the nodes at the boundary in other topologies so that the layout effect is more true.

Description

technical field [0001] The invention belongs to the field of network topology visualization, and in particular relates to a network topology visualization method related to geographic location information. Background technique [0002] With the increasing scale of modern networks and the increasing complexity of network structures, it is no longer the most effective way to analyze and describe networks in the traditional text form. Using visualization methods and related technical means, the text description of the network is converted into graphics, so that the network structure can be quickly and clearly presented to the user, and it is convenient to provide more effective reference for the control, management and optimization of the network. The technology that embodies the network is what we call network visualization. [0003] Network visualization is to convert abstract data into intuitive images, so the layout of network nodes and the connections between them are the...
