The present invention will be described in detail combined with specific embodiments below.
Synchronous network automatic protection method described in the present embodiment includes that the protection recovery process after alarm generates is eliminated with alarm
Reduction process afterwards, the protection restore process and include:
Step 1: delimiting protection zone in synchronous net in advance；
Step 2: the network element in synchronous net in protection zone issues alarm；
Step 3: needing to carry out protection recovery operation according to alarm judgement；
Step 4: according to alarm positioning failure source；
Step 5: the source of trouble being excluded from network topology, then carries out increment planning (resetting network topology)；
Step 6: carrying out clock source configuration by the result of increment planning, achieve the effect that protection restores.
The process further include:
Step 7: clock configuration information and associated alarm, test point before protection is restored (before resetting) (produce
The object of raw alarm) information stored (storage to reduction stack), used for sequential reduction process.
Wherein, protection zone described in above-mentioned steps 1 refers to a subnet in synchronous net, contains with following two
Justice:
1) network element in protection zone can be protected: when the small situation of its master/backup clock port clock signal
Under, the embodiment of the present invention can be its automatic other normal port of selection clock signal as clock recovery port, and select
Simultaneously non-tracking comes from this node (network element) to clock recovery port clock signal；
2) network element in protection zone may occur protection because of another network element in the same area and restore, and
Cause the clock of its own to configure to change.
Wherein, it needs to carry out protection recovery according to alarm judgement in the step 3, it can are as follows:
In protection zone certain network element generate clock source losing lock, degrade or network element configuration clock source signals it is all
Link all lossing signals, then with regard to needing to carry out protection recovery.Specifically, be exactly network element in protection zone generate losing lock,
Degrade alarm or synchronization loss (Lost of synchronous, LOS) alert when, it is possible to activation protection restore.
Wherein, positioning failure source described in the step 4 can include at least the following two kinds situation:
1) link signal is lost, and generates LOS alarm:
If the link in a network element where primary and backup clock source port all generates LOS alarm, LOS alarm
The link of generation is the source of trouble, this link will foreclose when carrying out protection and restoring, when not being re-used as transmitting
The link of clock signal.
2) external clock source LOS:
Assuming that network element A receives external clock BITS, and clock signal is transmitted to other network elements in network, if outside network element A
There is LOS alarm in clock port, and clock source losing lock occurs or degrade, then assert that the external clock source of network element A is asked
Topic, when protecting recovery, network element A will not be re-used as other network elements of external clock injection source into network and provide clock letter
Number, but ethernet clock signal is provided for it by other network elements as a common network element.
Wherein, protection recovery process described in step 5-6 includes:
Step 10: obtaining the clock configuration of the whole network；
Step 20: obtaining the network topology (network element topology i.e. in protection zone) for supporting synchronous recovery policy, and will determine
The source of trouble of position is removed；
Step 30: determining clock injection source (including the external clock decanting point, side supported in synchronous recovery policy network topology
The overseas abutment points (as shown in Figure 7) of strategy of boundary's point), if can not find clock injection source, (such as faulty link occurs in boundary point
Between the overseas abutment points of strategy, and without external clock decanting point in topology), planning failure again, direct jump procedure 60；
Step 40: to the network for supporting synchronous recovery policy, i.e., the network element topology in protection zone carries out increment planning, tool
Body is detailed in subsequent descriptions；
Step 50: the result that increment is planned being dissolved into the clock configuration of the whole network, and the configuration of the whole network clock is carried out brokenly
Ring processing, is specifically detailed in subsequent descriptions；
Step 60: the clock configuration conduct after clock configuration and variation before the network element variation that clock configuration is changed
The result of return；If planning failure again, empty result is returned；
Step 70: storage causes the information of the alarm that protection restores, test point (object) information that alerts and accordingly
The clock configuration information before protection restores occurs；
Here, cause the clock before the alarm of protection recovery, the object information alerted and corresponding generation protection restore
Configuration information is stored according to stack mode, this data base is known as " reduction stack " (as shown in figure 11).If there is multiple protections
Restore to occur in succession, then most first occurred protection restores the stacking of corresponding data elder generation, can finally be located at stack bottom, finally occur
Protection, which restores corresponding data, can be located at stack top.
It, can according to the clock source information of storage when causing alarm elimination accordingly on the object that protection restores
Directly replacement is gone back, and achievees the effect that reduction.
Wherein, the increment planning related content in the step 40 is as follows:
It should be noted that the network element as clock injection source only can provide clock in incremental planning process for other network elements
Source signal, the clock source configuration of itself will not have any change in increment planning.
The clock that these network elements can become in increment planning below injects source: the tactful domain of external clock decanting point, boundary point
Outer abutment points (shown in Fig. 7).
In addition, there are two types of the strategies that synchronous network planning is drawn: ring mode, shortest path mode, as shown in Figure 8.When increment is planned
Which kind of need to judge to have in planning (before update described above) using planning mode, increment planning is also required to adopt
It carries out in the same way.
Judge the method which kind of mode existing planning uses are as follows: all topologys in traverses network, if it find that having at least
One clock signal track path is poor once jumping cyclization, then being judged as existing synchronous net tracking planning strategy in the network and being
Otherwise ring mode is shortest path mode.
The progress increment planning includes the following steps:
Firstly, network topology to be split to the set of cyclization, chain；
Then, planning mode is judged, is planned if it is ring mode, then traversed all rings, chain, exist by network element
The sequencing planning clock signal track path arranged in ring, chain；If it is shortest path planning, then Di Jiesitela is used
Algorithm calculates each network element to the shortest path in clock injection source, and clock signal track path is planned according to shortest path；
Later, remaining available using clock signal track path obtained above as the active clock source of each network element
Signal source in clock source port is as standby clock source；
Finally, cyclic detection is done to the whole network, if it find that the clock source signals that some network element passes are believed according to clock
Number track path can return to this network element, then find cyclization, as shown in figure 9, needing to be carried out as follows brokenly ring processing.
Wherein, the broken ring method is as follows:
Firstly, two requirements drawn to synchronous network planning are introduced:
1) cannot be cyclic: the clock signal of network element tracking cannot come from this node；
2) have protection: the clock source of network element at least there are two, one of them be it is primary, others be it is spare, in master
It when something goes wrong can be in auto switching to spare clock source with clock source signals.
Above-mentioned two requirement can not reach simultaneously in some cases, and preferential in this case guarantee cannot be at
The requirement of ring, so there is the requirement of protection that can only accomplish to provide protection to greatest extent as far as possible.
The essence of above-mentioned broken ring method is: deleting the standby clock source signal of some network element, some network element is allowed to pass
Clock source signals be not returned to this network element (as shown in Figure 10).Based on the requirement that above-mentioned two synchronous network plannings are drawn, preferentially
A standby clock source on the network element with multiple standby clock sources is deleted, still there is guarantor to reach the network element after broken ring
The effect of shield.
Wherein, the reduction process after the alarm elimination includes:
Step 1: the network element in synchronous net in protection zone issues the message that alarm is eliminated；
Step 2: the information of the information of the alarm of elimination and corresponding test point (object for generating alarm) is stored to slow
Deposit collection；
Step 3: whether the information of the information and test point that check the alarm of reduction stack stack top is in cache set；If,
Then popped and carry out the restoring operation in step 4, at the same in cache set delete stack top the alarm information and inspection
The information of measuring point；Otherwise current process is exited；
Step 4: when carrying out restoring operation, it is only necessary to the clock configuration before the generation protection saved in stack restores will be restored and replaced
It gains；
Step 5: circulation above process 3-4, until the stack top until restoring stack is different from cache set.
Here, when alarm elimination occurs, the information of the alarm of elimination and corresponding test point (object) is stored first
Into a set S, which is collectively referred to as " cache set "；Whether the alarm for then checking the stack top D of reduction stack and test point are slow
It deposits in collection S, if the alarm of stack top D and test point are being popped and carrying out restoring operation, while being deleted in cache set S
The alarm of stack top D and test point recycle the above process, (process such as Figure 12 until the stack top of reduction stack is not belonging to cache set
It is shown).
When carrying out restoring operation, it is only necessary to the clock configuration replacement before the generation protection saved in stack restores will be restored and gone back
?.
The embodiment of the present invention can define network (Software Defined by Packet Transport Network deployment software
Network, SDN) controller implementation, it can also be implemented certainly by other equipment.
It is divided for example, following module can be carried out to equipment:
Human-computer interaction interface: network element can be chosen to create protection zone by it, the range of protection zone can be showed
And modify and delete to it, it can be provided when protection occurs and restores and prompt and show which network element is protected
Shield is restored, and can show which network element is restored when restoring；
District management module: being responsible for creation modification and deletes protection zone, allows when modifying protection zone by network element
Protection zone is added or excludes network element outside protection zone；
It alerts arbitration modules: receiving alarm and generate message.The source of trouble is found when alerting and generating and is planned to clock
Module say the word trigger protection restore process；
Clock planning module: it receives the order from alarm arbitration modules and carries out increment planning, reach what protection restored
Purpose；
Data restoring module: it receives alarm and eliminates message, and carry out reduction treatment.
In actual application, when generation of breaking down alerts, alarm passes to the alarm arbitration modules, alerts
Arbitration modules judge the source of trouble according to alarm, and starting protection restores process, send increment programming commands to clock planning module；
Clock planning module carries out increment planning to the clock signal track path of synchronous net topology behind debugging source,
New program results and the configuration of existing clock source are compared, changed clock source configuration data are found, by the number before variation
According to alarm arbitration modules are returned to, by the data application after variation into network element, generates protection and restore；
Alarm arbitration modules receive the data before the variation of clock planning module return, by the data and alarm before variation
Information association is got up, and data restoring module is pushed to, and data restoring module stores data into reduction stack.
After network element generates the message that alarm is eliminated, the message transmission of elimination is alerted to the data restoring module, data
Whether the information that recovery module eliminates alarm is stored into cache set, and judge the stack top warning information for restoring stack in cache set
In, if so, carrying out Data Restore Handles Technique.
