Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below by specific embodiment knot
Attached drawing is closed to be described in further detail the embodiment of the present invention.It should be appreciated that specific embodiment described herein is only used to
It explains the present invention, is not intended to limit the present invention.
Embodiment one:
In order to solve that there is difference SECTION (looped network in same physical link in polycyclic intersection network in the prior art
Protect section) OAM detection dispose excessive problem, reduce resource occupation, while realizing and being switched fast.The embodiment of the present invention provides
A kind of intersection loop multiplying segment for only needing to configure an OAM detection configuration and the OAM detection deployment of multiple SECTION can be realized
Alarm detection method.As shown in Figure 1, specific step is as follows for this method:
S101 obtains all looped network protection sections between two crossed nodes in networking intersecting ring.
In practical networking application, may usually there was only a physical link between two nodes of double-ring intersecting, or
Person only has a small number of physical links, but the looped network protection section in the two rings must share this physical link, even
In some other embodiment, the case where also having multiple access rings and converge ring intersection, then just having more
SECTION, and the looped network protection section obtained in the step is exactly the protection section between node that these rings intersect two-by-two.
S102 establishes group rules from all looped network protection sections and establishes a looped network protection stage group according to preset
Group, the looped network protection fragment group include at least two looped network protection sections (SECTION).
S103 configures an Operations,Administration And Maintenance detection configuration to the looped network protection fragment group.
S104 executes the Operations,Administration And Maintenance detection configuration detection local terminal MEP by the looped network protection fragment group
Alarm event between the MEP of opposite end, and the alarm event is passed by the looped network protection fragment group and is alerted
Processing.
In step s 102, it when resettling the looped network protection fragment group, is specifically got from step S101 first
All SECTION in select at least two SECTION for meeting preset condition, preset condition here refers to choosing
At least two SECTION must physical link having the same either share a physical link, then these are selected
SECTION out is combined into a looped network protection fragment group.
In the present embodiment, after completing group, need to carry out the looped network protection fragment group OAM detection configuration, i.e.,
It is execution step S103, and in this step, it is only necessary to configuring an OAM detection configuration can be realized to all in group
SECTION carries out OAM detection configuration.
In practical applications, it when configuring OAM detection configuration, can specifically be configured in the following manner:
It is protected firstly, it is necessary to select a looped network protection section from the looped network protection fragment group combined as main ring network
Section, and remaining looped network protection section is used as the slave looped network looped network protection section of main ring network protection section automatically；
Then, configuration OAM detection configuration is carried out to main SECTION.
In step S104, when carrying out the detection of alarm event, particular by detection local terminal MEO and the opposite end side MEP
Marker in the CCM message information of transmission, it is preferred that in practical applications, local terminal MEP is according to the preset time interval to right
MEP is held to send CCM message information, the CCM message information kind includes the marker of alarm event, and the marker is for indicating
It whether there is failure of connectivity between the local terminal MEP and opposite end MEP；Then main ring network protection section is by executing OAM detection
Configuration particularly detects whether marker is set to 1 to detect to the marker in CCM message information；If the mark
Know position be set to 1, then judge between the local terminal MEP and opposite end MEP there are failure of connectivity alarms.
In practical applications, local terminal MEP node can all be sent every preset sending time to opposite end MEP node
CCM message information, and opposite end MEP can carry out the connectivity judgement of link according to the CCM message information received, it is assumed that it is described
CCM agreement provides that the time cycle that message is sent is 3ms, and the fault verification rule set is when in week time for sending message
When after 3.5 times of times of phase there are no CCM message information is received, it is determined as failure, and carry out the mark of alarm event.
When opposite end MEP node does not receive the CCM message information within the preset waiting time, opposite end MEP section
Point searches the position of the host node in the Ethernet ring protection domain where itself according to preset contingency table in the contingency table
Confidence breath, and warning information is issued to the host node according to the location information；The waiting time is transmission CCM message information institute
The multiple to take time；Specifically, 3.5 times i.e. 10.5ms the time required to can be message sending cycle, therefore when MEP node exists
It finds not receive CCM message information after waiting 10.5ms, is just considered failure of connectivity, LOC alarm event is generated, by CCM
The home position RDI 1 in message, is sent to distal end MEP, therefore substantially reduces the time of fault detection and notice.
In step S104, when the alarm event is passed progress alarming processing, particular by master
SECTION is sent, and is specifically passed to the alarm event by main ring network protection section described from looped network protection section；Institute
State the Processing for removing alerted from the working condition of looped network protection section itself；
Alternatively, the alarm event is transferred on relevant to main ring network protection section by main ring network protection section
The Processing for removing that layer service service is alerted.
