Claim Text:
1. A tunnel fault detection method, comprising: receiving, by a traffic engineering (TE) node, a link fault report packet; determining, by the TE node, a faulty link in which a fault occurs according to the link fault report packet; detecting, by the TE node, whether one or more tunnels which use the TE node as an ingress node and pass through the faulty link exist; and if the one or more tunnels which use the TE node as the ingress node and pass through the faulty link exist, identifying the tunnels as faulty tunnels; wherein the detecting, by the TE node, whether one or more tunnels which use the TE node as an ingress node and pass through the faulty link exist, comprises: according to link information of links respectively passed through by multiple tunnels that use the TE node as the ingress node and according to link information of the faulty link, detecting, by the TE node, whether the one or more tunnels which use the TE node as the ingress node and pass through the faulty link exist.
