A background process is executed which dynamically determines nodes in a path from a start node to an end node. The background process examines a routing table of routing nodes in the path to determine changes in the path. Information regarding multiple paths between a first node and a second node of the network can be stored so that a point of primary failure can be more accurately determined.

Method of indicating a path in a computer network

A method and system for reducing fault analysis times in a network having a plurality of pollable objects. Poll responses are received from pollable objects, priorities are assigned to each received poll response in accordance with one or more of a received poll response value, a pollable object status and a type of pollable object, and the assigned priorities are processed and to determine any fault locations, wherein a pollable object with a higher priority is processed before a second pollable object with a lower priority. A status manager is operable to receive poll responses from one or more of the pollable objects, a status analyzer is operable to assign, in conjunction with one or more analyzers, priorities to each received poll response in accordance with the received poll response value, a pollable object status and a type of pollable object, and analyzers coupled the status analyzer use the assigned priorities and the corresponding received poll responses to determine a fault location.

Priority-based 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.
