Abstract:
1. A method for an intermediate node to locate a fault independently, wherein the intermediate node serves to forward a packet between a first end node and a second end node, the method comprising: creating, by the intermediate node, a test packet and sending the test packet to the first end node, wherein the test packet comprises address information of the second end node, and the test packet is used to trigger the first end node to send a response packet to the second end node; forwarding, by the intermediate node, the response packet from the first end node to the second end node; capturing, by the intermediate node, the response packet; analyzing, by the intermediate node according to a result of the packet capturing, whether a packet from the first end node to the second end node is able to be forwarded normally; and wherein the test packet further comprises address information of the first end node, the second end node address serves as a source address of the test packet, and the first end node address serves as a destination address of the test packet.
