Embodiment Construction

[0039] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0040] Such as figure 1 As shown, a method for network topology layout in this embodiment includes the following steps:

[0041] Step S1. Find the device nodes and the connection relationship between the device nodes in the managed network through automatic discovery, and save every two directly connected device nodes and their connection relationship as a link.

[0042] For a network of an application system that needs to establish a network topology (called a managed network), this embodiment can find and discover the managed network through automatic discovery methods such as network segment discovery, route discovery, and ARP discovery. All device nodes and the connection relationship between each device node. In the following...

Abstract

The invention discloses a network topology layout method and apparatus. The method comprises the following steps: storing each two interconnected device nodes and a connecting relation thereof as a link, finding a main link according to the occurrence time of each device node in a stored link list, and for the two device nodes of any link in the main link, calculating a layout distance between thetwo device nodes according to the number of branch links connected with the two device nodes; then using the device node having the largest number of connected main links as a starting drawing node,and laying the main links in sequence according to the layout distance between the device nodes and the number of the main links connected with the drawing node; and finally, calculating the includedangles of the branch links on the surrounding of the device nodes according to the number of the branch links connected with the device nodes, and laying the branch links according to the included angles of the branch links on the surrounding of the device nodes. By adoption of the method and apparatus disclosed by the invention, the network topology structure can be accurately drawn, and the network topology structure is clearly displayed.

Description

technical field [0001] The invention belongs to the technical field of network management, and in particular relates to a network topology layout method and device. Background technique [0002] Currently, in a large-scale video surveillance network, the operating status of video surveillance equipment is managed through an operation and maintenance platform (or called a network management platform). The traditional operation and maintenance platform can control the basic operating status of the monitoring equipment, such as online and offline, storage status, etc., but it only displays single or multiple abnormal equipment in a relatively simple way, and lacks an overall direct display of the entire system. As a result, it is impossible to quickly find out the cause of the abnormality in the monitoring system. [0003] Using an intuitive network topology to display the device nodes and connection relationships in the network, it has gradually been popularized and used in n...
