Abstract:
1. A method, comprising: transmitting, from a computing device in a computer network, a discovery message into the computer network; receiving, in response to the discovery message, a unicast reply from each node of a plurality of nodes in the computer network, each reply having a neighbor list of a corresponding node and a parent node for the corresponding node; creating a reference topology for the computer network based on the neighbor lists from the replies and a routing protocol shared by each of the plurality of nodes in the computer network, wherein the reference topology represents an ideal topology that should have been computed by the computer network when the plurality of nodes in the computer network are functioning properly; determining a current topology of the computer network based on the selected parent nodes from the replies, wherein the current topology is an actual topology that is currently computed for the computer network; and comparing the current topology to the reference topology to detect anomalies in the current topology.
