Problems solved by technology
For example, when an intermediate node or intermediate link fails, it is necessary to check the possible paths (often many) one by one to find out the fault point. If the network topology is complex, the troubleshooting usually takes a very long time. Troubleshooting It is also very difficult, and in the existing technology, technicians generally check manually, so it is difficult to troubleshoot in a timely and effective manner

A dynamic Tunnel fault diagnosis method, device and system. The dynamic Tunnel fault diagnosis method can include: storing routing information about a dynamic Tunnel by a webmaster; when it is discovered that the dynamic Tunnel failed, querying the latest routing information stored before the dynamic Tunnel failed and corresponding to the dynamic Tunnel; parsing the interface and network element through which the dynamic Tunnel passes according to the queried latest routing information about the dynamic Tunnel; and checking the interface and network element through which the dynamic Tunnel passes so as to learn of a suspected fault point in the dynamic Tunnel. The technical solution provided by the embodiments of the present invention is advantageous for reducing the complexity of troubleshooting of faults of the dynamic Tunnel and improving the troubleshooting efficiency of the dynamic Tunnel.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a dynamic tunnel fault diagnosis method, equipment and system. Background technique [0002] At present, a static tunnel (Tunnel) or a dynamic tunnel is usually used to complete service transmission in the bearer network, and there are thousands of bearer nodes in the bearer network. [0003] The function of the tunnel is to provide a path between two network nodes so that data packets can be transparently transmitted on this path. VPN Virtual Private Network (VPN Virtual Private Network) Tunnel generally refers to between VPN nodes (generally referred to as edge equipment (PE, Provider Edge)) of the PSN (Packet Switched Network) backbone network, or between VPN nodes and user nodes A virtual connection established between VPNs to transmit VPN packets. Tunnel is an integral part of building a VPN, and is used to transparently transmit VPN data packets from one VPN node t...
