Problems solved by technology

For the above-mentioned problems in the OAM protocol, these slow protocols also exist, that is, they are slow to perceive link failures, and cannot quickly detect problems in the case of link failures or packet loss, and switch backup links in time , leading to a serious decline in service quality

Embodiment 1

[0084] In this embodiment, a fixed time interval—fast detection waiting timeout time is set as a specified time, and the first OAM entity sends a fast detection message to the second OAM entity within the fast detection waiting timeout time.

[0085] image 3It is a flowchart of a method for quickly detecting an OAM protocol link in Embodiment 1 of the present invention. Such as image 3 As shown, the method includes:

[0086] In step 301, an OAM connection is established.

[0087] This step prepares for normal OAM communication. Including connection local connection establishment and remote connection establishment.

[0088] Step 302, the first OAM entity regularly sends the OAM message, and starts a receiving timer.

[0089] In this step, the sending interval of the first OAM entity to send the message is 1 second. In the present invention, the timing time of the receiving timer started by the first OAM entity can be the same as that of the prior art, that is, the exis...

Embodiment 2

[0123] In this embodiment, when the first OAM entity sends a fast detection message, it is repeatedly sent at a fixed time interval, and the maximum number of detection times is preset, and the specified time for receiving the fast detection response message is the maximum number of detection times and sending the fast detection message The product of the time intervals.

[0124] In this embodiment, the process of establishing a connection and maintaining a connection state between the OAM entities at both ends is the same as that in Embodiment 1, and will not be repeated here. Assume that the preset maximum number of probes is 5. The process that the first OAM entity performs fast detection when a link may fail is as follows:

[0125] When the first OAM entity does not receive the handshake OAM message sent by the second OAM entity within the specified time, the fast timer is started, and according to the setting of the fast timer, it is sent to the second OAM entity at a pe...

Abstract

This invention discloses one rapid test method, which comprises the following steps: first network part receives second part to keep connection status message to send rapid detection message to second network part; if the first network part receives feedback rapid message in set time then to judge whether linkage is normal and to judge fault. This invention also discloses one rapid test device composed of receive module and rapid test module.

Description

technical field [0001] The invention relates to a detection technology of a communication link, in particular to a method and equipment for realizing fast detection. Background technique [0002] Operations, Administration and Maintenance (OAM) is a set of standards proposed for simple and effective management of the network in a more complex network. This standard is based on the IEEE 802.3ah protocol specification and mainly solves the final Management issues for the one-mile network. [0003] In the definition of IEEE 802.3ah OAM, OAM mainly provides the following functions: OAMDISCOVERY connection establishment; link monitoring; remote loop test; remote MIB variable acquisition. [0004] Among them, the working principle of OAM connection establishment: [0005] The first OAM entity establishes an OAM connection with the second OAM entity, that is, an OAM DISCOVERY process. OAM DISCOVERY connection establishment is a mechanism for a first OAM entity to discover a seco...
