Problems solved by technology

[0013] However, if the PE does not receive the PING response message from the CE, it may be because the user has just shut down the CE, or the user temporarily unplugs the network cable plug of the CE from the network user line interface in addition to the failure of the subscriber line.
The existing technology only judges whether the line is faulty based on not receiving the PING response message, which will wrongly judge these situations as line faults, and further cause the operator's line maintenance resources to be greatly wasted.

Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0037] In the present invention, when the CE is in a power-off state or the CE network connector is disconnected from the network, the user line is self-looped, so that after the PE sends a PING request message, it receives the PING request message sent by itself, that is, the loop return message. The invention also correspondingly improves the processing mechanism of PING in the OAM sublayer of PE, and distinguishes this state from subscriber line failure.

[0038] The formation of the ringback message is as follows image 3 as shown, image 3 The user line has been set to the loop state on the CE side, and the PE sends a PING request message. , the PING request message is then returned to the PE through the line connected to the receiving end of the PE, so what the PE receives is the...

Abstract

The invention discloses an Ethernet OAM method, which comprises the following steps: installing user linear to become circuit state, when user device CE cuts power or CE network adaptor cuts form network; sending PING request message to CE by transport operation business device; ascertaining the user line normal, when PE received message is ring message. The invention simplifies the operation, which is easy to realize.

Description

technical field [0001] The invention relates to the field of Ethernet operation management and maintenance (Operations, Administration & Maintenance, OAM), in particular to a method for detecting the state of an Ethernet subscriber line. Background technique [0002] At the access layer of the Ethernet, the user equipment (Customer Equipment, CE) is generally connected to the operator equipment (Provider Equipment, PE) through the user line, the CE refers to the user's computer, and the PE refers to the user's computer directly connected to the user. Connected operator equipment, such as a switch, the subscriber line is generally a twisted pair or a category 5 line. If the subscriber line fails, users will not be able to connect to the network to obtain services, so timely detection of subscriber line failure is a very important technical issue. [0003] The Institute of Electrical and Electronics Engineers (IEEE) 801.1AH standard describes an Ethernet Operations Administra...
