Method and system for detecting failures of network nodes

摘要

Systems and methods for detecting device failures in a network having nodes coupled to a central controller, in which a first of the nodes communicates with the central controller via a second of the nodes. When the second node determines that the first node has not transmitted a predetermined number of messages over a predefined number of time periods, the second node provides a failure alert to the central controller. The central controller records a failure alert received from the second node in a log. Based on a set of failure alerts received from a number of nodes recorded in the log, the central controller determines whether the first node has failed.

1. A central controller that detects device failures in a network, said network including a plurality of nodes coupled to the central controller, wherein a first of said nodes communicates with the central controller via a second of said nodes, said central controller having a processor that executes program instructions stored in a memory device that cause the central controller to:
record a failure alert received from the second node in a log stored on the memory device, said second node providing said failure alert based on a determination that the first node has not transmitted at least one message within a predefined time period; determine, by the processor, that the first node has failed based on a set of failure alerts recorded in the log in association with the first node; and generate, when the processor determines that the first node has failed, a failure notification causing a notification device to indicate a failure.
