Method and system for network fault analysis

A method and system for locating a fault in a network. According to the system, an address analyzer and interface analyzer of a network manager of the network detect that there is a failure associated with a node of the network, a node analyzer of the network manager determines if the node responds to a poll, and if the node does not respond to the poll, a neighbor analyzer of the network manager models the failure, further comprising determining a number and a polling of a plurality of neighbor nodes of the node and assigning the fault in accordance with the number and the polling of the plurality of neighbor nodes According to the method, in response to a node having one or more of one or more addresses and one or more interfaces that fail to respond to a poll, polling the node and polling a plurality of neighbor nodes of the node and assigning the fault in accordance with the polling of the node and a number and the polling of the plurality of neighbor nodes.
