Problems solved by technology

However, the destination LSR only triggers the switchover because of the AIS alarm. It is also impossible to know the specific fault location. Manual intervention is required to check each network element point by point. The troubleshooting efficiency is too low. With the more PW hops, the location The more difficult it is to fail

Abstract

The embodiment of the invention provides a method and device for transmitting fault messages, and relates to the field of communication. The method and device can improve network fault locating efficiency and reduce fault duration. The method comprises the steps that a label switching router is used for detecting links adjacent to the device, if the label switching router detects faults of the links, fault messages of the links are obtained, the fault messages comprise fault types, fault positions, fault channel types and fault channel identification messages, and alarming messages including the fault messages are sent to sink ends in the data traffic transmitting direction, so that the sink ends analyze the alarming messages to obtain the fault messages. The method and device are used for transmitting fault messages.

Description

technical field [0001] The invention relates to the communication field, in particular to a fault information transmission method and equipment. Background technique [0002] The communication industry standard "Technical Requirements for Packet Transport Network Equipment" defines the alarm indication signal (Alarm Indication Signal, AIS) function of the packet transport network (Packet Transport Network, PTN) equipment: it is mainly used when a failure is detected in the service layer, Suppress client-level alerts. When the service layer (MEG End Point, MEP) detects the loss of continuity (Loss Of Continuity, LOC) or signal failure (Signal Failure, SF), it sends an AIS signal to the destination MEP of the client layer to suppress the LOC of the client layer Wait for the warning signal. [0003] In the prior art, in a multiprotocol label switching (Multiprotocol Label Switching, MPLS) network, when the label switching router (Label Switching Router, LSR) of the label swit...
