Method and system for finding link, first network element and network management equipment

Abstract

The invention discloses a method and system for finding a link, a first network element and network management equipment. The method for finding the link comprises the steps that step1, the first network element receives a finding parameter sent by a second physical interface of a second network element from a first physical interface, the finding parameter is the only parameter which represents the second physical interface, the first physical interface is a physical interface arranged on the first network element, and the second physical interface is a physical interface arranged on the second network element; step2, the first network element reports the finding parameter and an identification of the first physical interface to the network management equipment so that the network management equipment can find the link between the second physical interface and the first physical interface according to the finding parameter and the identification of the first physical interface. According to the mode, the method and system for finding the link, the first network element and the network management equipment can reduce complexity of finding the link, can improve operation capacity and maintenance capacity of a network, and can reduce operation cost and maintenance cost.

Description

technical field [0001] The present invention relates to the technical field of network management, in particular to a method for discovering links, a system for discovering links, and a first network element and network management equipment. Background technique [0002] In recent years, the number of network users has grown explosively, and the scale of the network is constantly expanding. However, users' requirements for bandwidth and service quality are constantly increasing. Therefore, network operation and maintenance capabilities are particularly important. The basis of network operation and maintenance lies in the network topology. The network topology is a specific physical or logical arrangement among the members of the network. Its main purpose is to obtain and maintain the existence information of each network element in the network and the connection between each network element. When a fault occurs in the network, the fault node can be quickly located according ...

Problems solved by technology

[0004] However, the inventors of the present application have discovered in long-term research and development that in the prior art, after the network management equipment obtains the basic information of all network elements, each network element needs to receive status information from each other. Therefore, when there are a large number of network elements to be discovered, the work high volume and complexity

In addition, the topology discovery method in the prior art has many limitations, and it can only target network elements in a single network domain, which is not conducive to network standardization construction
