Embodiment
Below by accompanying drawing and specific embodiment, technical solution of the present invention is described in detail.
Embodiment one:
Be illustrated in figure 1 a kind of chain circuit detecting method flow chart based on operation management maintain OAM in the embodiment of the present invention, the method comprises the steps:
Step 101, the OAM checkout equipment detected for Link State receives the OAM administrative message of opposite end for the 2nd OAM checkout equipment transmission of Link State detection.
First it should be noted that, concrete scheme in this embodiment of the present invention is applied in OAM link detecting technology, when carrying out link detecting, one OAM checkout equipment and the 2nd OAM checkout equipment periodically can send detection messages each other, and then according to the message number received, an OAM checkout equipment and the 2nd OAM checkout equipment determine whether link exception occurs.
If when the OAM detection module in the prior art in the 2nd OAM checkout equipment or the 2nd OAM checkout equipment is being restarted or in the OAM software function upgrading of the 2nd OAM checkout equipment or the 2nd OAM checkout equipment, the connecting interface of OAM detection module switches, one OAM checkout equipment cannot carry out OAM protocol with the 2nd OAM checkout equipment, namely cannot receive the detection messages of opposite end, now an OAM checkout equipment cannot receive detection messages, in prior art, an OAM checkout equipment will send warning information, but now not there is exception in link, it is not the abnormal communication abnormality caused of link, therefore this warning information be mistake carry out alarm to link is abnormal.
In embodiments of the present invention in order to avoid above-mentioned problem, therefore an OAM checkout equipment and the 2nd OAM detect and to comprise or chain is connected to a message administration module in embodiments of the present invention, this message administration module independently controls, that is: the restarting or close the normal operation that can not have influence on message administration module of an OAM checkout equipment and the 2nd OAM checkout equipment, and whether the link detecting function that this message administration module can detect an OAM checkout equipment and the 2nd OAM checkout equipment is normally run, if when this message administration module determines the link detecting dysfunction of the 2nd OAM checkout equipment self, then the message administration module by comprising or connecting is generated an OAM administrative message by the 2nd OAM checkout equipment, and send an OAM administrative message to an OAM checkout equipment.
Specifically, when the 2nd OAM checkout equipment detects that the link detecting function of self occurs abnormal, 2nd OAM checkout equipment will generate a kind of type of message of expansion, such as (this agreement is of course not only limitted to) in 802.1ag agreement, when 2nd OAM checkout equipment generates an OAM administrative message, detected state message tlv triple TLV, reboot time message tlv triple TLV, packet loss counting message tlv triple TLV is carried in this message, wherein:
Detected state TLV comprises: TLV type (type)=9, length(message length)=1 byte, it is normal that value (value)=1or2(1 characterizes detected state, and 2 characterize detected state extremely), specifically as shown in table 1:
| TLV type=9 |
| Length=1 |
| Value=1or2 |
Table 1
Reboot time TLV comprises: TLV type (type)=10, length(message length)=1 byte, value (value)=time value (second), specifically as shown in table 2:
| TLV type=10 |
| Length=1 |
| Value=time value |
Table 2
Packet loss counting TLV comprises: TLV type (type)=11, length(message length)=8 bytes, value (value)=packet loss counting, specifically as shown in table 3:
| TLV type=11 |
| Length=8 |
| Value=packet loss counts |
Table 3
After generation comprises an OAM administrative message of above-mentioned information, an OAM administrative message is sent to an OAM checkout equipment by the 2nd OAM checkout equipment.
A now OAM checkout equipment OAM administrative message that reception the 2nd OAM checkout equipment is sent, and perform step 102.
Step 102, when carry in an OAM administrative message for characterize the 2nd OAM checkout equipment be in abnormality time, an OAM checkout equipment cuts out self link detecting function.
One OAM checkout equipment is after receiving an OAM administrative message, one OAM checkout equipment will be resolved an OAM administrative message, that is in an OAM administrative message, the information whether the 2nd OAM checkout equipment link detecting function is in abnormality is obtained, if carry in an OAM administrative message sign the 2nd OAM checkout equipment be in abnormality under information time, an OAM checkout equipment will directly cut out the link detecting function of self.
Such as, after one OAM checkout equipment receives an OAM administrative message, the value of detected state information that first one OAM checkout equipment will parse in an OAM administrative message, when the value of this detected state information is 2, then illustrate that the measuring ability of the 2nd OAM checkout equipment is in abnormality, now an OAM checkout equipment will cut out the link detecting function of self.
It should be noted that, abnormality is herein that the OAM detection module in the 2nd OAM checkout equipment or the 2nd OAM checkout equipment is being restarted or the connecting interface switching etc. of OAM detection module in the software function upgrading of the 2nd OAM checkout equipment or the 2nd OAM checkout equipment, these are all the adjustment of the running status due to the 2nd OAM checkout equipment self extremely, and be not that exception really occurs link, therefore by the link detecting function of temporary close the one OAM checkout equipment, an OAM checkout equipment can be effectively avoided to send the fault alarm information of link failure.
Further, the time value for characterizing link detecting function reboot time information is also carried in an OAM administrative message, one OAM checkout equipment will determine this time value, and timing from when receiving an OAM administrative message, before this time value, what the one OAM checkout equipment received that the 2nd OAM checkout equipment sends carry for characterize the 2nd OAM checkout equipment recover the 2nd OAM administrative message of normal condition time, then an OAM checkout equipment restarts the link detecting function of self immediately, and link is detected, if link detecting fault, then send warning information,
When arriving described time value, what the one OAM checkout equipment did not still receive that the 2nd OAM checkout equipment sends carry for characterize the 2nd OAM checkout equipment recover the 2nd OAM administrative message of normal condition time, then an OAM checkout equipment will restart the link detecting function of self, and link is detected, if link detecting fault, then send warning information.
Specifically, 2nd OAM checkout equipment is when sending an OAM administrative message to an OAM checkout equipment, a time value (such as 3 seconds) can be added in an OAM administrative message, this time value is used for an OAM checkout equipment control link measuring ability reboot time, if when any instant in 3 seconds receives sign the 2nd OAM checkout equipment recovery normal 2nd OAM administrative message, one OAM will restart the link detecting function of self immediately, that is when an OAM checkout equipment received the 2nd OAM administrative message in 3 seconds, one OAM checkout equipment will determine that the 2nd OAM checkout equipment temporarily occurs exception, warning information can't be sent.
If but after 3 seconds, still do not receive the 2nd OAM administrative message, now an OAM checkout equipment will restart the link detecting function of self, and carries out normal link detecting, if when link detecting is abnormal, send warning information.
The of short duration exception of OAM checkout equipment can be effectively avoided to send link failure warning information by the time value of the reboot time information in an OAM administrative message; also ensure that link occurs to send warning information timely when exception occurs really for exception or OAM checkout equipment really; also ensure that the measuring ability of an OAM checkout equipment can not be in closed condition in addition always, ensure that the normal operation of link detecting.
Further, packet loss count information is also carried in an OAM administrative message, when an OAM checkout equipment gets the 2nd OAM administrative message of the 2nd OAM checkout equipment transmission, this packet loss count information is carried in the 3rd OAM administrative message and is sent to the 2nd OAM checkout equipment by the one OAM checkout equipment, to make the 2nd OAM checkout equipment by the packet loss value in this packet loss count information as the packet loss threshold value judging Link State.
That is an OAM checkout equipment temporarily saves the detected parameters of the 2nd OAM checkout equipment; when the parafunctional 2nd OAM checkout equipment of link detecting recovers normal link detecting function; the detected parameters of the 2nd OAM checkout equipment preserved before is returned to the 2nd OAM checkout equipment by the one OAM checkout equipment; thus can ensure that the 2nd OAM checkout equipment can adjust detected parameters accurately after link detecting dysfunction is recovered, and then the 2nd OAM checkout equipment can be detected accurately to link.
After the OAM checkout equipment detected for Link State in embodiment one receives an OAM administrative message of the 2nd OAM checkout equipment transmission that opposite end is detected for Link State, when carry in an OAM administrative message for characterize the 2nd OAM checkout equipment be in the information of abnormality time, one OAM checkout equipment will cut out the link detecting function of self, thus there is exception and cause the problem sending link-down alarm and erroneous calculations link packet drop rate of opposite end OAM checkout equipment mistake in the OAM checkout equipment avoiding one end, and then improve the accuracy of OAM checkout equipment to link detecting.
