Abstract

The present invention discloses a method for obtaining network information. The technical solution of the invention is as follows: when the network element managed by a network management system obtains the device information of the adjacent network element which has changed device information, transmitting the device information to the network management system; the device information comprises one or a plurality of messages selected from the IP address, the interface address and the device property of the network element with the changed device information; the network management system obtains the device information of the managed network element according to the device information and forms a network topology according to the device information. The invention furthermore provides a device for obtaining the network information, which comprises an information obtaining module and a topology constructing module. The technical solution of the invention increases the speed for obtaining information between the network elements and reduces the effect to the network load in the prior art.

Description

technical field [0001] The present invention relates to the technical field of network communication, and more specifically, to a method and device for acquiring network information. Background technique [0002] In the network management system, presenting the information of each management device in the network through the network topology is an important part of realizing network management. Because the intuitive network topology configuration information can not only reflect the layout of each management device in the network, but also provide a shortcut for users to observe the network structure from multiple angles, so as to quickly diagnose and eliminate network faults. However, with the continuous expansion of the network scale and the increasingly complex network structure, it becomes more and more difficult to obtain network topology configuration information, so the function of automatic network element discovery becomes more and more important for the network man...
