Problems solved by technology

[0016] In the process of realizing the present invention, the inventor found that, for the BFD interface linkage function, the interface is in many forms, such as multiple interfaces multiplexing one member link, one interface contains multiple member links, etc., cannot be used effectively
For example, for multiple interfaces to reuse one member link, each interface must be configured with at least one BFD session detection, which is very inefficient; for an interface that contains multiple member links, the current interface linkage function cannot effectively support it.

Embodiment Construction

[0036] The embodiment of the present invention provides a method for detecting interface faults and a technical solution for network node equipment. BFD is used to directly detect the status of member links of the interface, and then determine the status of the interface according to the status of the member links, so as to implement various forms of Efficient BFD is performed on interface member links.

[0037] The technical solutions of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] Referring to FIG. 2 , it is a schematic structural diagram of a network node device according to an embodiment of the present invention. According to the figure, the network node device includes:

[0039] The link detection module 1 is used to establish a BFD session and perform BFD detection on the member links of the interface;

[0040] The interface management module 2 is configured to determine whether the i...

Abstract

This invention discloses a method for testing faults of interfaces including: setting up BFD session on every member link and carrying out BFD test, when a fault is tested, then the faulty state of the link is reported to the interface to determine if said interface is faulty. This invention also discloses a network node device.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method for detecting interface faults and network node equipment. Background technique [0002] With the development of communication technology, especially the growing demand for carrying real-time and delay-sensitive services such as NGN and 3G on IP networks, how to protect the quality of data transmission, how to quickly locate the fault when there is a problem in data transmission, and It has become an important problem to be solved urgently to reduce the loss of data packets through corresponding processing. [0003] In order to solve the above problems, the industry currently proposes an Operational Maintainability (OAM) technology. OAM technology can automatically detect various faults in the network, and then take corresponding remedial measures to avoid the expansion of faults, eliminate faults, and reduce or eliminate the negative impact of faults. Current OAM technol...
