Abstract

A fault detection method, route node and system are provided by the embodiments of the present invention. The fault detection method includes: transmitting a detection packet to a neighbor of neighbor (NN) node via a neighbor node; if a response packet, which is returned via the neighbor node by the NN node, is not received, determining that faults exist in the forwarding path via the neighbor node to the NN node. The embodiments of the invention can solve the technical problem in the prior art of slow awareness and time-consuming search for the forwarding-fault so as to improve the efficiency of the network operation and maintenance and reduce the operation and maintenance cost.
