Abstract

The invention discloses a method and a device for detecting a link failure based on 802.3ah OAM (Operation, Administration and Maintenance). The method comprises the following steps of: periodically sending an equipment information acquiring message by a network element to a user terminal; receiving an equipment information message reported by the user terminal, and storing the equipment information; and querying the stored equipment information when the link state between the network element and the user terminal fails, and judging the cause of the failure. The device comprises an equipment information acquiring message issuing unit, an equipment information storing unit and a link failure detecting unit. The method solves the problem that the failure of the link state can not be detected when the link state between the network element and the user terminal is abnormal and the link is even broken in the prior art.

Description

technical field [0001] The invention relates to the field of broadband access, in particular to an 802.3ah OAM-based link abnormality detection method and device. Background technique [0002] With the development of communication technology, various broadband access technologies are constantly being introduced, playing an increasingly important role in the "last mile" transmission bottleneck. The rapid expansion of digital broadband users has brought severe challenges to the operation and maintenance of telecom operators. [0003] The 802.3ah OAM (Operation Administration and Maintenance) standard protocol introduced by IEEE defines a series of methods to monitor and detect whether a single point-to-point link is normal, so it is very suitable for telecom operators Use network elements to manage and maintain the "last mile" link between user terminal equipment. [0004] The OAMPDU (OAM Protocol Data Unit, OAM Protocol Data Unit) frame structure defined by the 802.3ah OAM ...
