Abstract: A method for an intermediate node to locate a fault independently, where the intermediate node serves to forward a packet between a first end node and a second end node, the method includes: creating a test packet and sending the test packet to the first end node, where the test packet includes 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 the response packet from the first end node to the second end node; capturing the response packet ; and analyzing, according to a result of the packet capturing, whether a packet from the first end node to the second end node can be forwarded normally.

Abstract translation: 一种用于中间节点独立定位故障的方法，其中所述中间节点用于在第一端节点和第二端节点之间转发分组，所述方法包括：创建测试分组并将所述测试分组发送到所述第一终端节点 其中所述测试分组包括所述第二端节点的地址信息，并且所述测试分组用于触发所述第一端节点向所述第二端节点发送响应分组; 将响应分组从第一端节点转发到第二端节点; 捕获响应数据包; 以及根据所述分组捕获的结果，分析从所述第一端节点到所述第二端节点的分组是否可以正常转发。
