In the embodiment of the present invention, network topology structure is utilized to determine chain object and the process of ring object, specifically can include but not limited to following manner: step 1, from network topology structure, analyze all of network element device, and each network element device is abstracted into an object, and the link having between two network element devices of annexation is abstracted into line object.Step 2, in the link objects table being pre-configured with record all-pair as and all line objects.Step 3, for each some object, perform following steps: step A, judge in this link objects table whether only one line object of correspondence；If it is, perform step B；Step B, from this link objects table, remove the line object of correspondence, and judge another object of this line object, a whether only corresponding line object in link objects table；Step B is continued executing with if it is, return；If it is not, then perform step C；Step C, the link that the line object of all removals forms is defined as chain object.Step 4, by link objects table remaining line object composition loop be defined as ring object.
Below in conjunction with the application scenarios shown in Fig. 1, the determination process of chain object and ring object is illustrated.
In step 1, the network element device analyzed from network topology structure specifically includes: network element device R1, network element device R2, network element device R3, network element device R4, network element device R5, network element device R6, network element device R7, network element device R8, network element device R9, network element device R10, network element device R11, network element device L1, network element device L2, network element device L3, and each network element device is abstracted into an object.nullThe line object that topological structure Network Based obtains specifically includes: the link between line object 1-network element device L1 and network element device R8，Link between line object 2-network element device R8 and network element device R9，Link between line object 3-network element device R9 and network element device R10，Link between line object 4-network element device R10 and network element device R1，Link between line object 5-network element device R10 and network element device R11，Link between line object 6-network element device R11 and network element device R4，Link between line object 7-network element device R1 and network element device R2，Link between line object 8-network element device R2 and network element device R3，Link between line object 9-network element device R3 and network element device R4，Link between line object 10-network element device R4 and network element device R5，Link between line object 11-network element device R5 and network element device R6，Link between line object 12-network element device R6 and network element device R7，Link between line object 13-network element device R7 and network element device R8，Link between line object 14-network element device R7 and network element device L2，Link between line object 15-network element device L2 and network element device L3.
In step 2, in link objects table record all-pair as and all line objects.
In step 3, for an object (network element device R1, network element device R2, network element device R3, network element device R4, network element device R5, network element device R6, network element device R7, network element device R8, network element device R9, network element device R10, network element device R11, network element device L2), all corresponding at least two line objects in link objects table, object 4 as homologous pair in network element device R1 and line object 7, the homologous pair object 7 of network element device R2 and line object 8.For these objects, the process of end step 3.
For an object (network element device L1), in link objects table, a corresponding line object 1, removes line object 1 from link objects table.Another object (network element device R8) corresponding two line objects (line object 2, line object 13) in link objects table due to line object 1, therefore, the link that the line object 1 of removal forms is defined as chain object, and namely chain object includes the link between network element device L1 and network element device R8.For an object (network element device L3), in link objects table, a corresponding line object 15, removes line object 15 from link objects table.Due to another object (network element device L2) of line object 15 only corresponding line object 14 (line object 15 be moved out of after, only homologous pair object 14) in link objects table, therefore, from link objects table, remove line object 14.Another object (network element device R7) corresponding two line objects (line object 12, line object 13) in link objects table due to line object 14, therefore, the link that the line object 15 of removal and line object 14 form is defined as chain object, and namely chain object includes the link between the link between network element device L3 and network element device L2, network element device L2 and network element device L7.So far, obtaining two chain objects altogether, the two chain object is respectively as follows: the link between chain object 1-network element device L1 and network element device R8；Link between chain object 2-network element device L3 and network element device L2, the link between network element device L2 and network element device L7.
In step 4, after removing line object 1, line object 14, line object 15 from link objects table, in link objects table, remaining line object includes line object 2, line object 3, line object 4, line object 5, line object 6, line object 7, line object 8, line object 9, line object 10, line object 11, line object 12, line object 13, and the loop of remaining line object composition in link objects table is defined as ring object.
In order to obtain the loop of line object composition, certain can be put object (such as network element device R1) as starting point object, from this starting point object line object (such as line object 7), first find another object (such as network element device R2) of this line object (such as line object 7), and from line object (such as line object 8) corresponding to another object (such as network element device R2), continue to search for another object (such as network element device R3) of this line object (such as line object 8), by that analogy, after finding this starting point object, just can by all line objects one loop of composition of process in this search procedure.
Such as, during using network element device R1 as starting point object, line object 7, line object 8, line object 9, line object 6, line object 5, line object 4 form a loop.During using network element device R1 as starting point object, line object 7, line object 8, line object 9, line object 10, line object 11, line object 12, line object 13, line object 2, line object 3, line object 4 form a loop.During using network element device R10 as starting point object, line object 5, line object 6, line object 10, line object 11, line object 12, line object 13, line object 2, line object 3 form a loop.Certainly, above three example is the example of starting point object, no matter using which network element device as starting point object, all can form above three loop, and only comprise these three loop in the network topology structure shown in Fig. 1.
Further, it is possible to these three loop is defined as three ring objects of correspondence, as ring object 1 includes: line object 7, line object 8, line object 9, line object 6, line object 5, line object 4.Ring object 2 includes: line object 7, line object 8, line object 9, line object 10, line object 11, line object 12, line object 13, line object 2, line object 3, line object 4.Ring object 3 includes: line object 5, line object 6, line object 10, line object 11, line object 12, line object 13, line object 2, line object 3.In addition, for source network element device and purpose network element device, if source network element device and purpose network element device are two network element devices on ring object, then for the communication link between source network element device and purpose network element device, above-mentioned each ring object can be split as two ring objects, if source network element device is network element device R10, when purpose network element device is network element device R4, for the communication link between network element device R10 and network element device R4, above-mentioned ring object 1 is split as ring object 11 (line object 4, line object 7, line object 8, line object 9) and ring object 12 (line object 5, line object 6), and for the fractionation of other ring object 2 and ring object 3, similar with the fractionation mode of ring object 1, at this, it is no longer repeated.
Certainly; the determination mode of above-mentioned chain object and ring object is an example; the embodiment of the present invention is not limited to the determination mode of this chain object and ring object, all be capable of determining that above-mentioned chain object 1, chain object 2, ring object 1, ring object 2, ring object 3 mode all within scope.
Step 202, when getting interruption class alarm, obtains and interrupts the position that class alarm occurs.
Wherein, alarm type can include but not limited to: interrupts class alarm (indicating that link interrupts), hydraulic performance decline alarm (indicating the hydraulic performance decline of network element device) etc., in embodiments of the present invention, it is for the handling process interrupting class alarm, for the processing procedure of other alarm type, no longer repeat in detail.
In the embodiment of the present invention, when getting interruption class alarm, obtain the process interrupting the position that class alarm occurs, specifically can include but not limited to following manner: when receiving the interruption class alarm that two network element devices with annexation send, then the position that the alarm of acquisition interruption class occurs is the central link between two network element devices；Or, when receiving the interruption class alarm that two network element devices without annexation send, then the position that the alarm of acquisition interruption class occurs is the network element device between two network element devices.
Such as, when network element device R7 breaks down, then network element device R6 will be unable to receive the data from network element device R7, and sends interruption class alarm to Network Management Equipment.Additionally, when network element device R7 breaks down, then network element device R8 will be unable to receive the data from network element device R7, and sends interruption class alarm to Network Management Equipment.Based on this, Network Management Equipment when receiving the alarm of the network element device R6 without annexation and the network element device R8 interruption class sent, then can get and interrupt position that class alarm occurs particularly as follows: network element device 7 between network element device R6 and network element device R8.
Again such as, when the central link between network element device R1 and network element device R2 breaks down, then network element device R1 will be unable to receive the data from network element device R2, and sends interruption class alarm to Network Management Equipment.Additionally, network element device R2 also will be unable to receive the data from network element device R1, and send interruption class alarm to Network Management Equipment.Based on this, Network Management Equipment when receiving the alarm of the network element device R1 with annexation and the network element device R2 interruption class sent, then can get and interrupt position that class alarm occurs particularly as follows: central link between network element device R1 and network element device R2.
Certainly; it is an example that the mode of the position that class alarm occurs is interrupted in above-mentioned acquisition; the embodiment of the present invention is not limited to this mode obtaining and interrupting the position that class alarm occurs; all modes interrupting the position that class alarm occurs that can obtain are all within scope; only can get interruption class alarm and be to occur on network element device, also be to occur in the central link between network element device.
Step 203, occurs on network element device if interrupting class alarm, then the communication link between source network element device and purpose network element device is through chain object, it is judged that whether this chain object comprises this network element device.
If it is, directly perform step 204.If it is not, then the communication link that can determine that between this source network element device and this purpose network element device, this passed chain object does not interrupt.
Step 204, it is determined that the communication link between source network element device and purpose network element device has occurred and that interruption.
In the embodiment of the present invention, occur on network element device when interrupting class alarm, and the communication link between source network element device and purpose network element device is through ring object, then judge whether this ring object comprises this network element device.If not comprising this network element device, then can determine that the communication link between this source network element device and this purpose network element device, this passed ring object does not interrupt.If comprising this network element device, then judge that whether the communication link between source network element device and purpose network element device is only to there being a ring object.If only to there being a ring object, it is determined that the communication link between source network element device and purpose network element device has occurred and that interruption.If corresponding multiple ring object, when all ring objects all comprise the network element device corresponding with interrupting class alarm, it is determined that the communication link between source network element device and purpose network element device has occurred and that interruption；When all ring objects all do not comprise the network element device corresponding with interrupting class alarm, it is determined that the communication link between source network element device and purpose network element device interrupts.
In the embodiment of the present invention, occur in the central link between network element device when interrupting class alarm, and the communication link between source network element device and purpose network element device is through ring object, then judge whether this ring object comprises this central link.If not comprising this central link, then can determine that the communication link between this source network element device and this purpose network element device, this passed ring object does not interrupt.If comprising this central link, then judge that whether the communication link between source network element device and purpose network element device is only to there being a ring object.If only to there being a ring object, it is determined that the communication link between source network element device and purpose network element device has occurred and that interruption.If corresponding multiple ring object, when all ring objects all comprise the central link corresponding with interrupting class alarm, it is determined that the communication link between source network element device and purpose network element device has occurred and that interruption；When all ring objects all do not comprise the central link corresponding with interrupting class alarm, it is determined that the communication link between source network element device and purpose network element device interrupts.
Below in conjunction with whether communication link is occurred the process interrupted to be described in detail by concrete application scenarios.
Such as, assume that interrupting class alarm occurs on network element device R7, source network element device is network element device L3, purpose network element device is network element device R10, then the communication link between network element device L3 and network element device R10 is through chain object 2 (link between network element device L3 and network element device L2, the link between network element device L2 and network element device L7)., it is judged that whether this chain object 2 comprises this network element device R7, and owing to this chain object 2 comprises this network element device R7, accordingly, it is determined that the communication link between network element device L3 and network element device R10 has occurred and that interruption, communication link is recovered by follow-up needs therefore.
Such as, assume that interrupting class alarm occurs on network element device R7, source network element device is network element device L1, and purpose network element device is network element device R10, then the communication link between network element device L1 and network element device R10 is through chain object 1 (link between network element device L1 and network element device R8).Therefore, it is judged that whether this chain object 1 comprises this network element device R7, and owing to this chain object 1 does not comprise this network element device R7, accordingly, it is determined that the communication link between network element device L1 and network element device R10 interrupts.
