Method and device for IPv4 and IPv6 network failure detection and location

The invention discloses an Ipv4 and Ipv6 network failure detecting and locating method and apparatus of OSPF route monitoring system, and belongs to the technical field of the computer network management. The method comprises the steps that a route monitoring system receives the chain circuit state broadcasting which identifies a network state, generates a network incident through analyzing the type of the chain circuit state broadcasting and the signal change, and then inserts the network incident into a network incident data table; according to the attribution of the network incident, the route monitoring system makes a relevant analysis on the network incident and the prior network incident to generate failure information; the route monitoring system inserts the failure information into a network failure data table, and reports the failure information to a network manager. The apparatus comprises a receiving module, an analysis generating module, a generation module, and a reporting module. The invention uses the route monitoring system to collect the chain circuit state broadcasting which identifies the network state, and to store and analyze the chain circuit state broadcasting, thereby realizing the purpose of timely detecting and locating the failure which arises in the network.
