Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Along with the development of optical communication technique, the equipment network mode is complicated day by day flexibly, and common optical-fiber network is by optical network management system and optical network device.In the correlation technique, optical network management system and optical network device all provide defencive function, realize various types of protection operational modes.In the system that is made up of protection controller and network management system, the protection controller is switched the protection group execute protection that needs execute protection and switch, and still, is not that all protections are organized the protection of whole successful execution and switched.
The flow chart of the method that Fig. 2 switches for the protection according to the realization protection group of the embodiment of the invention.This method mainly comprises following processing:
Step S202: network management system receive the protection controller the protection group is protected switch after the PSE Protection Switch Event of transmission;
Step S204: according to PSE Protection Switch Event verification protection group whether all protection switch successfully;
Step S206: if there are not whole successful execution, then notice protection controller protection group that successful execution protection is not switched repeats the protection switching operation.
In the correlation technique; after protection controller execute protection is switched; the result is not switched in protection and carry out verification; and protect once more and switch; and in the present embodiment for whether all protection switch success and carried out verification, thereby solved the problem that protection group that correlation technique switches for successful execution protection not can not correctly start protection.Adopt the method for the embodiment of the invention, can effectively improve the success rate that the protection of protection group is switched, and can reduce O﹠M personnel's the upkeep operation time effectively.
Preferably, above-mentioned steps S204 may further include following processing:
(1) network management system is determined the protection group number that needs execute protection to switch;
(2) network management system judges whether the PSE Protection Switch Event number that reports is consistent with protection group number;
(3) if then network management system determines that protection organizes the protection of whole successful execution and switch;
(4) otherwise, then network management system determines that the protection group does not have the protection of whole successful execution to switch.
In preferred implementation process, the whole protection group execute protection switching operations of protection controller to needing execute protection to switch, and the protection group is switched success or not put down in writing with the daily record form.The protection group that the successful execution protection is switched is sent to network management system with the PSE Protection Switch Event form.Network management system is determined all protection groups according to the PSE Protection Switch Event of protection controller report, and whether whole successful execution protection is switched.
By above-mentioned processing, network management system is carried out verification to the protection group after switching, and can determine not switch the protection group of success, thereby for follow-up switching provides foundation, has reached the effect of automatic detection protection group switch status.
Preferably, before network management system need to determine protection group number that execute protection switches, can also comprise following processing:
(1) calculates each professional transmission path;
(2) calculate the veneer port that is associated in the transmission path;
(3) veneer port and protection group are mated, determine the protection group that to switch when each veneer port breaks down.
In preferred implementation process; the protection group that need switch when network management system needs in advance definite each veneer port to break down promptly needs to generate the condition that many protections group is switched simultaneously, that is to say; when certain port triggering is switched, should there be what protection groups to switch simultaneously simultaneously.
By above-mentioned processing, can judge current which protection group and should switch, thereby can determine whether the protection group has all been carried out protection and switched, effectively improved the success rate that the protection of protection group is switched.
Preferably, in the check results of execution in step S204 for being that then network management system directly is back to user side with check results.
By above-mentioned processing, can the real-time prompting user protect the state of switching, thereby can improve user experience.

(2) the protection controller carries out verification to the protection group of protection group id correspondence, and check results is fed back to network management system to generate daily record;
(3) the protection group execute protection switching operation of protection controller to confirming that not successful execution protection is switched.
In preferred implementation process, two kinds of implementations can be arranged, first kind of scheme is: after the network management system verification, directly notice protection controller protection group that successful execution protection is not switched repeats the protection switching operation.Wherein, the successful execution protection protection group of switching not is to obtain (specifically can referring to above-mentioned steps S202-step S206) after the network management system verification.
Second kind of scheme is: after the network management system verification; the protection group id that the protection of successful execution is not switched is sent to the protection controller; the protection controller is carrying out the verification second time to the protection group of these protection group id correspondences, and the protection group execute protection switching operation to confirming that not successful execution protection is switched.For example, network management system verification for the first time have protection group 1, protection group 3, protection group 4 not the successful execution protection switch, then the identification information with protection group 1, protection group 3, protection group 4 is sent to the protection controller, the protection controller carries out the verification second time to protection group 1, protection group 3, protection group 4, perhaps twice check results is identical, then protects controller that 4 execute protection switching operations are organized in protection group 1, protection group 3, protection; Perhaps twice check results difference after the verification of protection controller, has only not successful execution protection switching operation of protection group 1, protection group 3, then protects controller that 3 execute protections are organized in protection group 1, protection and switches.
By the interaction process of network management system with the protection controller, carry out twice verification, the accuracy of verification can be improved, thereby the operating efficiency that follow-up execute protection is switched can be improved.
Preferably, before execution in step S206, can also comprise following processing:
(1) network management system detects the alarm status in protection path every predetermined amount of time;
(2) after each the detection, network management system notice protection controller detects the alarm status in protection path;
(3) protect the testing result of controller inconsistent if NMS is unified, then network management system generates the inconsistent prompting incident of alarm status;
(4) if the testing result unanimity that NMS is unified and protected controller, the then alarm status in network management system record protection path;
(5) network management system is determined the protection path of can execute protection switching according to testing result.
By above-mentioned processing; network management system and the state of protecting controller real-time monitoring and protecting group middle controller veneer and service board; the running status that guarantees the controller veneer is consistent with single board state; determine the protection path of can execute protection switching further to improve protection by this scheme and to switch success rate.
Further describe above-mentioned preferred embodiment below in conjunction with Fig. 3.
Fig. 3 is the flow chart according to the network management system monitoring and protecting path of the embodiment of the invention.This monitoring flow process can comprise following processing:
Step S302: the current protection group that disposes of equipment, business to be protected, network management system can regularly be monitored the protection path, and simultaneously the protection controller is monitored;
Step S304: the alarm status in network management system periodic monitor protection path, and synchronously alarm status information is notified to the protection controller and carries out the secondary verification;
Step S306: if protect the path with nowhere to turn to the police, and the testing result of network management system is consistent with protection controller testing result, and then webmaster record protection path in daily record is normal;
Step S308: if protect the path with nowhere to turn to the police, but the result that network management system is monitored is inconsistent with protection monitoring control devices result, and then webmaster produces event prompt network management protection state and protects controller state inconsistent;
Step S310: if there is alarm in the protection path, and the testing result of network management system is consistent with the testing result of protection controller, and then webmaster provides event prompt according to the alarm that reports and protects the path unusual.
Step S312: if there is alarm in the protection path; but the result of network management system monitoring is inconsistent with protection monitoring control devices result; then to produce event prompt network management protection state inconsistent and the protection path status is unusual with the protection controller state for webmaster, points out current alarm status simultaneously.
By above-mentioned processing, the state of monitoring and protecting group middle controller veneer and service board can guarantee that the running status of controller veneer is consistent with single board state in real time.Determine which protection path can switch by execute protection, thereby can improve the protection success rate of switching, and can effectively reduce O﹠M personnel's the upkeep operation time.
Fig. 4 is for realizing the flow chart of the method that the protection of protection group is switched according to the preferred embodiment of the invention.This method comprises following processing:
Step S402: if Working service interrupts, can switch, if the protection channel abnormal is not then switched according to the professional situation of protection;
Step S404:, then switch and report the incident of switching if the protection passage is normal;
Step S406: switch finish after, network management system protects group to switch verification according to the PSE Protection Switch Event that reports;
Step S408: if the protection group is all normally switched, then direct log of network management system and real-time display result are by the user;
Step S410: switch if also have protection to organize not successful execution protection, then network management system offers the protection controller with unusual protection group information, carries out secondary by the protection controller and switches verification;
Step S412: after the verification of protection controller is finished, report relevant information to give network management system, and generate the log record check results by network management system.
Step S414: the protection group execute protection switching operation that the protection controller is switched the not successful execution protection of confirming.
Wherein, checking procedure is the switch status of verification protection group not only, also will carry out and protect the mutual of controller.Hence one can see that, and present embodiment adopts above-mentioned second kind of scheme.Adopt second kind of scheme; can improve the verification correctness; because network management system is to carry out verification according to the PSE Protection Switch Event that the protection controller is uploaded; in the process that has a plurality of protection groups to switch simultaneously; system works efficient is lower; may lose message in upload procedure, therefore in the case, the verification accuracy of network management system may be not high.
In preferred implementation process; after step S414; the situation that may still exist the protection group successfully not switch; at this moment; can point out the user to carry out associative operation; also can continue the protection group of successfully not switching protected and switch, perhaps send PSE Protection Switch Event to network management system, the operation that repeats verification and switch.Specifically can according to circumstances decide.
