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.

Embodiment Construction

[0027] The embodiment of the present invention realizes the drawing of the topology map by creating a simple graphic object for the resource in the topology layer to draw the graphic corresponding to the resource. Because only a simple graphic object needs to be created, compared with creating a graphic object containing all attribute information, it reduces the occupied memory and improves the drawing speed of the topology map.

[0028] Wherein, resources include network elements and links.

[0029] Graphic objects include simple graphic objects, complete graphic objects and accessory graphic objects. The simple graphic object represents the most basic graphic object needed to complete the drawing of network elements or links, and expresses the type and attribute of resources in a graphic way. The complete graphic object includes the graphic objects needed to draw all the attributes of network elements or links, and is a composite object. It can display more information tha...

Abstract

A method for drawing a topological graph is disclosed and is used to realize the drawing of the topological graph. The method reduces occupied memory and improves the drawing speed of the topological graph. The method includes: creating a simple graph object according to a type attribute of resources; calculating a screen density value according to the number of network elements of the resources located in a screen visible area and judging whether the screen density value is greater than a preset screen density threshold value; creating an integrated graph object for the resources according to all the attributes of the resources located in the screen visible area when the judgment result is negative. An apparatus used to realize the method is also disclosed.

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...
