Embodiment
Technical solution of the present invention is described in detail below by accompanying drawing and specific embodiment.
Embodiment one：
It is a kind of chain circuit detecting method flow chart based on operation management maintainance OAM in the embodiment of the present invention as shown in Figure 1,
This method comprises the following steps:
Step 101, the first OAM detection devices for Link State detection receive that opposite end is used for Link State detection the
The first OAM management messages that two OAM detection devices are sent.
Firstly the need of explanation, the concrete scheme in the embodiment of the present invention is applied in OAM link detecting technologies,
When carrying out link detecting, the first OAM detection devices and the 2nd OAM detection devices can periodically send detection report between each other
Text, then the first OAM detection devices and the 2nd OAM detection devices determine whether link occurs according to the message number received
It is abnormal.
If the OAM detection modules in the 2nd OAM detection devices or the 2nd OAM detection devices are in the prior art
Restart OAM detection modules in OAM software function upgrading either the 2nd OAM detection devices of the 2nd OAM detection devices
Connecting interface switching when, the first OAM detection devices will be unable to the 2nd OAM detection devices carry out OAM protocols, also
The detection messages that can not receive opposite end, now the first OAM detection devices can not receive detection messages, in the prior art this
One OAM detection devices will send warning information, but now exception does not occur for link, be not that link is extremely caused logical
News are abnormal, therefore the warning information is being alerted extremely to link for mistake.
In embodiments of the present invention in order to avoid it is above-mentioned the problem of, therefore in embodiments of the present invention the first OAM detection set
Standby and the 2nd OAM detections include or chain is connected to a message management module, the message management module independent control, i.e.,：First
The normal operation for not interfering with message management module is restarted or closed to OAM detection devices and the 2nd OAM detection devices,
And the message management module can detect the first OAM detection devices and the link detecting function of the 2nd OAM detection devices
No normal operation, if the message management module determines the link detecting dysfunction of the 2nd OAM detection devices itself, then should
2nd OAM detection devices by by comprising or the message management module of connection generate the first OAM and manage message, and to first
OAM detection devices send the first OAM management messages.
Specifically, when the 2nd OAM detection devices detect that the link detecting function of itself occurs abnormal, this second
OAM detection devices will generate a kind of type of message of extension, such as in 802.1ag agreements（Of course not it is only limitted to the association
View）, when the 2nd OAM detection devices generate the first OAM management messages, detection state message triple is carried in the message
TLV, reboot time message triple TLV, packet loss count message triple TLV, wherein：
Detection state TLV includes：TLV type (type)=9, length（Message length）=1 byte, value (value)=
1or2（1 sign detection state is normal, and 2 characterize detection abnormal states）, it is specific as shown in table 1：
| TLV type=9 |
| Length=1 |
| Value=1or2 |
Table 1
Reboot time TLV includes：TLV type (type)=10, length（Message length）=1 byte, value (value)=when
Between be worth（Second）, it is specific as shown in table 2：
| TLV type=10 |
| Length=1 |
| Value=time value |
Table 2
Packet loss, which counts TLV, to be included：TLV type (type)=11, length（Message length）=8 bytes, value (value)=lose
Bag counts, specific as shown in table 3：
| TLV type=11 |
| Length=8 |
| Value=packet loss counts |
Table 3
After the management messages of the first OAM comprising above- mentioned information are generated, the 2nd OAM detection devices are by the first OAM
Management message is sent to the first OAM detection devices.
Now the first OAM that the 2nd OAM detection devices of reception are sent is managed message by the first OAM detection devices, and
Perform step 102.
Step 102, it is in abnormality for characterizing the 2nd OAM detection devices when the first OAM manages to carry in message
When, the first OAM detection devices close the link detecting function of itself.
For first OAM detection devices after the first OAM management messages are received, the first OAM detection devices will be to the
One OAM management messages are parsed, that is to say, that obtain the 2nd OAM detection device link detectings in the first OAM manages message
Whether function is in the information of abnormality, is characterized if being carried in the first OAM management messages at the 2nd OAM detection devices
During information under abnormality, the first OAM detection devices will directly close the link detecting function of itself.
Such as after the first OAM detection devices receive the first OAM management messages, the first OAM detection devices will
The value of the detection status information in the first OAM management messages is parsed first, when the value of the detection status information is 2, then
Illustrate that the detection function of the 2nd OAM detection devices is in abnormality, now the first OAM detection devices will close the chain of itself
Road detection function.
It should be noted that abnormality herein is in the 2nd OAM detection device or the 2nd OAM detection devices
OAM detection modules are being restarted in software function upgrading either the 2nd OAM detection devices of the 2nd OAM detection devices
The connecting interface switching of OAM detection modules etc., these are all due to the 2nd OAM detection devices running status of itself extremely
Adjustment, and be not that exception really occurs for link, therefore by the link detecting function of the OAM detection devices of temporary close the first,
The first OAM detection devices can be effectively avoided to send the fault alarm information of link failure.
Further, also carried in the first OAM manages message for characterizing link detecting function reboot time information
Time value, the first OAM detection devices will determine the time value, and the timing since when being connected to the first OAM management messages,
Before the time value, what the first OAM detection devices received that the 2nd OAM detection devices send carries for characterizing the 2nd OAM
When detection device recovers the 2nd OAM management messages of normal condition, then the first OAM detection devices restart the link inspection of itself immediately
Brake, and link is detected, if link detecting failure, then send warning information；
When reaching the time value, what the first OAM detection devices did not still receive that the 2nd OAM detection devices send takes
When managing message with the 2nd OAM for recovering normal condition for characterizing the 2nd OAM detection devices, then the first OAM detection devices
The link detecting function of itself will be restarted, and link is detected, if link detecting failure, then send warning information.
Specifically, the 2nd OAM detection devices to the first OAM detection devices when sending the first OAM management messages, meeting
A time value is added in the first OAM manages message（Such as 3 seconds）, the time value is for the control of the first OAM detection devices
Link detecting function reboot time, if any instant in 3 seconds, which receives, characterizes the recovery of the 2nd OAM detection devices normally
When 2nd OAM manages message, the first OAM will restart the link detecting function of itself immediately, that is to say, that the first OAM detections are set
During for receiving the 2nd OAM management messages in 3 seconds, the first OAM detection devices will determine that the 2nd OAM detection devices temporarily go out
It is now abnormal, warning information can't be sent.
If but after 3 seconds, still do not receive the 2nd OAM management messages, now the first OAM detection devices are still
The link detecting function of itself will be restarted, and carry out normal link detecting, if during link detecting exception, sending alarm letter
Breath.
The time value of the reboot time information in message is managed by the first OAM can effectively avoid OAM detections from setting
Standby of short duration exception sends link failure warning information, and it is certain to also ensure that abnormal either OAM detection devices occur really for link
Generation can timely send warning information when abnormal, also ensure that the detection function of the first OAM detection devices will not one in addition
Directly it is closed, ensure that the normal operation of link detecting.
Further, packet loss count information is also carried in the first OAM manages message, is obtained in the first OAM detection devices
When getting the 2nd OAM management messages of the 2nd OAM detection devices transmission, the first OAM detection devices are by the packet loss count information
Carry and sent in the 3rd OAM manages message to the 2nd OAM detection devices, so that the 2nd OAM detection devices count the packet loss
Packet loss value in information is as the packet loss threshold value for judging Link State.
That is the first OAM detection devices temporarily save the detection parameters of the 2nd OAM detection devices, work as link detecting
When 2nd OAM detection devices of dysfunction recover normal link detecting function, the first OAM detection devices will preserve before
The detection parameters of the 2nd OAM detection devices return to the 2nd OAM detection devices, thereby may be ensured that the 2nd OAM detection devices
Detection parameters can be accurately adjusted after the recovery of link detecting dysfunction, and then enable the 2nd OAM detection devices
Accurately link is detected.
The first OAM detection devices for being used for Link State detection in embodiment one receive opposite end for Link State detection
The first OAM management messages that send of the 2nd OAM detection devices after, carried when the first OAM is managed in message for characterizing the
When two OAM detection devices are in the information of abnormality, the first OAM detection devices will close the link detecting function of itself, from
And the OAM detection devices for avoiding one end occur abnormal and cause opposite end OAM detection device mistakes send link-down alarm
And the problem of erroneous calculations link packet drop rate, and then improve accuracy of the OAM detection devices to link detecting.
Embodiment two：
Information exchange flow chart in the system formed below by the first OAM detection devices and the 2nd OAM equipment is to reality
The method applied in example one and embodiment two illustrates：

Step 203, the first OAM detection devices manage the detection status information in message according to the first OAM and close itself
Link detecting function, and preserve time value and packet loss count information in the reboot time information in the first OAM management messages
In packet loss count；
Step 204, before time value, the first OAM detection devices detect whether to receive the transmission of the 2nd OAM detection devices
The OAM detection device link detecting functional rehabilitation normal conditions of sign the 2nd the 2nd OAM management message, if it is not, then performing step
Rapid 205, if so, then performing step 206；
Step 205, arrival time value is determined whether, if reaching the time value, the first OAM detection devices restart itself
Link detecting function, and link is detected, if testing result characterizes link exception, send warning information；
Step 206, the first OAM detection devices restart the link detecting function of itself immediately, and generate and carry packet loss counting
The 3rd OAM management messages of information, and the 3rd OAM management messages are sent to the 2nd OAM detection devices；
Step 207, after the 2nd OAM detection devices receive the 3rd OAM management messages, the 3rd OAM management messages are obtained
In the packet loss that includes of packet loss count information count, and the packet loss is counted into the packet loss threshold value as judgement link packet drop rate.
, can be timely when the link detecting function of the 2nd OAM detection devices in the system occurs abnormal in embodiment two
Inform the first OAM detection devices so that the first OAM detection devices close the link detecting function of itself, now the first OAM is examined
Measurement equipment will not send the abnormal alarm of link, when re-launched between within value, the link detecting function of the 2nd OAM detection devices
