Network Fault Recognition Method Based on Network Topology Monitoring

Abstract

In the field of development of cyberspace, faults are not only the cause of abnormal network functions, but also the cause of network fault phenomenon. Network fault identification solves the problem of "Is there a fault?" "What's the trouble?" And "Where did the malfunction occur?". The corresponding problems are fault detection, fault type judgment and fault located, and the solutions of these problems depend on fault phenomena. Experience shows that network fault phenomena are closely related to network topology. By analyzing network characteristics and network fault correlation, using network fault identification method based on network topology monitoring, establishing the relationship between network fault phenomena and network fault and forming identifying parties of various network faults, that realizes the identification of switch and link faults, provides important help for network faults encountered in network management and development of cyberspace.
