Method and device for drawing topological graph

Abstract

The invention discloses a method for drawing a topological graph, which is used for realizing the drawing of the topological graph, reduces occupied internal memory and enhances the drawing speed of the topological graph. The method comprises the following steps of: constructing a simple graphic object by computer equipment according to the type attribute of a resource; calculating the density value of a screen by the computer equipment according to the number of network elements in the resource positioned in a visible area of the screen and judging whether the density value of the screen is greater than the preset density threshold of the screen or not; and when a judgment result is that the density value of the screen is not greater than the preset density threshold of the screen, constructing an integral graphic object for the resource by the computer equipment according to all the attributes of the resource positioned in the visible area of the screen. The invention also disclosesa device which is used for realizing the method.

Description

technical field [0001] The invention relates to a network equipment management system, in particular to a method and device for drawing a topology map. Background technique [0002] The topology map graphically displays the management devices and the network connection relationship between each device in the network device management system. [0003] In practical applications, the topology map is very important, especially when there are many devices in the network device management system, the topology map is needed to visually display the connection relationship between each device. Topology maps are inseparable from applications such as network reconstruction, learning network principles, and network security protection. Without a topology map, it is often difficult to understand a network clearly. [0004] At present, the drawing of the topology map is to first determine all the management devices and their connection relationships in the topology layer, and create a gr...

Problems solved by technology

With the continuous increase of communication devices, the number of management objects in the network device management system continues to increase, and the number of network elements and links that need to be displayed in a topology layer also increases. The relatively complete method of drawing all attachments obviously consumes a lot of memory, and the drawing speed is relatively low. Therefore, this traditional drawing method can no longer meet the requirements of the current network device management system.
