In this step, if causing the relaying to interrupt to the progress cutover of cutover paragraph to described, illustrate if described
In the cutover period described in cutover when cutover paragraph, being normally carried out for business will affect, it at this time can be by first cutover
Conflict judging result is determined as causing to conflict in the relaying level.
In step 102-24, first cutover conflict judging result is determined as within the cutover period to institute
Stating will not cause to conflict to the progress cutover of cutover paragraph in the relaying level.
In this step, if not will lead to the relaying interruption to the progress cutover of cutover paragraph to described, cutover is carried out
When, it can be ensured that business is normally carried out, and the judging result that first cutover can conflict at this time is determined as will not be described
It causes to conflict in relaying level.
In addition to considering other than whether the relaying level conflicts, in the embodiment of the present disclosure, it is also necessary to which consideration is being cut
When connecing, whether current failure, which will lead to the relaying, is interrupted, i.e., determines the second cutover consequences of hostilities in the relaying level,
As shown in fig. 6, step 102 may include:
In step 102-21 ', according to the fault warning information of the wavelength-division system obtained in advance, current failure is judged
Whether will lead to the relaying to interrupt.
In this step, it is being determined that carrying out cutover to cutover paragraph according to the cutover single pair not will cause in described
After interruption, it is also necessary to further judge whether current failure will lead to the relaying and interrupt.
If the relaying is ring, need to judge in the ring where whether current failure will lead to second relaying
It is disconnected.As shown in Figure 5A, it is assumed that a certain business transmission for directly arriving relaying B to the corresponding relaying A of cutover paragraph in cutover paragraph
Link then needs to judge whether another had to the business datum chain road of relaying B by relaying D, relaying C by relaying A again
After being in malfunction, if determining that relaying C is in malfunction according to the fault warning information, when carrying out cutover,
It will lead to two business datum links to interrupt, the business of influence is normally carried out.It can determine that current failure will lead to described second
Ring where relaying interrupts.If can determine current failure among the above after non-failure not and will lead to second relaying
The ring at place interrupts.
If the relaying has parallel protection, it is corresponding to need to judge whether current failure will lead to second relaying
Concurrently protect link down.As shown in Figure 5 B, when carrying out cutover, business datum link 1 can be interrupted, if parallel business number
According to having trunk failure on link 2, it is determined that the failure is the target faults, will lead to business datum link 2 and interrupts, shadow
The business of sound is normally carried out, and can determine that current failure will lead to second relaying and corresponding concurrently protect link down.If
The non-failure of relaying on business datum link 2 then can determine current failure not and will lead to that second relaying is corresponding simultaneously
Hair protection link down.
If the ring that current failure will lead to second relaying place interrupts or current failure will lead in described second
Link down is concurrently protected after corresponding, determines that current failure will lead to second relaying and interrupt, thens follow the steps 102-
22 ', it is no to then follow the steps 102-23 '.
In step 102-22 ', it is right within the cutover period that second cutover conflict judging result is determined as
It is described to cause to conflict with current failure to the progress cutover of cutover paragraph.
If current failure will lead to the relaying and interrupt, illustrate when carrying out cutover, current failure will lead to and this to
The corresponding two business datum links of cutover paragraph interrupt, and business datum can not be transmitted, and the normal of business is also just unable to ensure
It carries out, accordingly, it is determined that second cutover conflict judging result is to carry out cutover meeting and current failure to cutover paragraph to described
It causes to conflict.
In step 102-23 ', it is right within the cutover period that second cutover conflict judging result is determined as
It is described to cause to conflict with current failure to the progress cutover of cutover paragraph.
If current failure not will lead to the relaying and interrupt, illustrate when carrying out cutover, in addition to described to cutover paragraph
Except corresponding business datum link, another business datum link is not interrupted, it can be ensured that and business is normally carried out, therefore,
Determine that the second cutover conflict judging result is that will not cause to conflict with current failure to the progress cutover of cutover paragraph to described.
<circuit level>
The first cutover consequences of hostilities is determined in the circuit level of client, as shown in fig. 7, step 102 can wrap
It includes:
In step 102-31, believed according to the cutover information searching with the circuit to the corresponding circuit of cutover paragraph
Breath.
