Problems solved by technology

[0002] With the continuous expansion of network scale, the difficulty of network maintenance and management is also increasing. Once the intricate link connection between devices is wrong, it is very difficult and inefficient to compare and find faults only by relying on the reference topology map.

Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The nodes in the embodiment of the present invention all enable Link Layer Discovery Protocol (Link Layer Discovery Protocol, LLDP), and wherein this LLDP agreement is a kind of proximity discovery protocol, and it is Ethernet network equipment, as switchboard, router and wireless local area network access point etc. define a standard method, so that it can announce its own existence to other nodes in the network, and save the discovery information of each adjacent device, and each port of all devices stores the information defining itself, if necessary Send update messages to their neighbors, which store the information in standard SNMP MIBs (Management Information Bases). The network management system can query the current connec...

Abstract

The invention provides a method, device and system for implementing detection on network topology fault of nodes in a network, wherein the method comprises the steps of: initiating a link layer discovery protocol, and obtaining current topological neighbor information through a topological neighbor discovery process; comparing the current topological neighbor information with pre-stored reference topological neighbor information, and giving an alarm prompt regarding topological error if the current topological neighbor information and the reference topological neighbor information are inconsistent.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, device and system for nodes in a network to detect network topology faults. Background technique [0002] With the continuous expansion of network scale, the difficulty of network maintenance and management is also increasing. Once the intricate link connection between devices is wrong, it is very difficult and inefficient to compare and find faults only by relying on the reference topology diagram. How to quickly and accurately locate faults such as connection errors, redundancy and disconnection in the network topology is an urgent problem to be solved. Contents of the invention [0003] The invention provides a detection method, device and system for network topology faults, which can quickly detect network topology faults. [0004] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions: [00...
