Method and device for failure diagnosis of multi-protocol label switching virtual private network (MPLS VPN)

Abstract

The invention discloses a method and a device for the failure diagnosis of a multi-protocol label switching virtual private network (MPLS VPN). The method comprises the following steps of: selecting source equipment and destination equipment between which communication is interrupted, and determining a link connection relationship between the source equipment and the destination equipment; determining a network layer and equipment with a communication failure according to the link connection relationship between the source equipment and the destination equipment; and displaying the network layer and the equipment with the communication failure in a topology way. By the method and the device in the embodiment of the invention, a VPN communication failure can be directly and rapidly positioned, and communication failure diagnosis efficiency can be greatly improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for realizing MPLS VPN (Multi protocol Label Switching Virtual Private Network, multi protocol label switching virtual private network) fault diagnosis. Background technique [0002] At present, with the development and expansion of the scale of enterprises, the demand for cross-regional interconnection of enterprises is also increasing. How to ensure the security between the headquarters and branches of the enterprise and realize fast and effective interconnection and communication has become a necessity and an important aspect of the enterprise network. ability. Among them, VPN technology is a solution to ensure the secure interconnection between enterprise headquarters and branches, and between different enterprises. At present, the VPN technology widely used in user enterprise interconnection scenarios is MPLS VPN technology. The MPLS VPN te...

However, since this method uses an abstract list for link selection, when multiple target links are fault-handled, the user needs to remember the link and then filter and select, and the processing efficiency is low; and, due to the need to Viewing the connectivity one by one at the three protocol levels of VPN, MPLS, and IP will also reduce the diagnostic efficiency; at the same time, when presenting the diagnostic results, the fault point and its adjacency are not intuitive due to the abstract list, and it is often necessary to compare again Topological diagrams are used to judge specific fault points, which makes the diagnosis results not intuitive enough
