Problems solved by technology

However, after combining the position information of the nodes, the layout area of ​​the topology is often an irregular polygon, and the layout in the irregular polygon will cause the problem of uneven layout: the nodes in the center area of ​​the polygon are dense, and the nodes in the corner area of ​​​​the polygon are sparse.
For the topology layout in irregular areas, there is still a lack of related solutions

Embodiment Construction

[0047] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below in conjunction with the accompanying drawings.

[0048] Network topology visualization is very important for people to obtain network structure information. Traditional network topology layout methods usually use the computer screen as the display target, and the topological layout area is a regular area (such as a rectangular screen, a rectangular software window, etc.). However, in actual use, it is usually necessary to layout in an irregular area. For example, when the topology and geographic information are combined, the topology needs to be laid out within the scope of a certain country or region, which is an irregular area. For the topology layout in irregular regions, there is still a lack of related solutions.

[0049] In view of the above problems, the present invention proposes a netw...

Abstract

The invention discloses a network topology visualization method in an irregular region. Aiming at the problems that there is no effective solution to the topology layout in an irregular region currently, the method comprises the steps: dividing the irregular region into a plurality of parts according to the geometric features of the irregular region; building a stress model in each part accordingto the idea of force guide, and performing multiple iterations under the limit conditions, thereby enabling the intensive nodes at the center of the region to spread towards the edge and corners, andfinally enabling the nodes in the whole irregular region to be in uniform and beautiful layout.

Description

technical field [0001] The invention belongs to the field of network structure analysis, in particular to a network topology visualization technology. Background technique [0002] With the development of society, we have entered the era of information explosion, and the scale of relational data networks is getting larger and larger. Traditional text representation methods can no longer quickly and accurately enable data researchers to quickly understand and analyze the structural information of a network. The topology image generated by network topology visualization allows data researchers to observe the overall situation of the network topology and the details of any substructure at a glance. The layout of network topology visualization includes logical layout and physical layout. The logical layout is mainly to show the logical structure of the network, and the layout is relatively simple; important practical significance. [0003] The most concerned topic in the curre...
