Fault diagnosis method based on network historical topology traffic

Abstract

The invention discloses a fault diagnosis method based on network historical topology traffic, which comprises the following steps: carrying out data acquisition through a self-defined SNMP-MIB, carrying out traffic data acquisition based on traffic, associating traffic data with topology data, and storing topology and traffic associated data at the moment; generating historical traffic topological data based on the time dimension; enabling an administrator to retrieve and analyze the historical topology flow data based on the time dimension, so that fault positioning and reason analysis are carried out, and the fault position and reason can be quickly positioned.

Description

technical field [0001] The invention belongs to the field of network communication, and in particular relates to a fault diagnosis method based on network historical topology flow. Background technique [0002] Computer networks have become an indispensable part of various human activities. However, the rapid growth of user groups and the huge amount of data transmission are putting more and more pressure on the network, the network structure is becoming more and more complex, the controllability of the network is gradually decreasing, and the occurrence of network failures is becoming more and more frequent, which greatly affects The normal operation of the network is affected, which brings huge losses to the economy. Therefore, how to effectively manage the network has become a problem that people pay more and more attention to. [0003] Network management ensures reliable, stable, continuous, efficient and safe operation of the network by taking a series of actions and ...

Problems solved by technology

[0005] Currently, there are many network management systems. These systems can only monitor the current network status and diagnose the faults of the current environment. They cannot trace back the historical status of the network and the causes of faults, and cannot subdivide traffic and forward traffic. Path and network topology data are not stored, and have not been established with traffic data. Network administrators can only locate and analyze network faults through their own memory status of the network, and then determine the cause of the fault. The quality requirements are very high, the fault location efficiency is low, and the error is large, and it is generally difficult to trace the cause of the fault in the past time period
