[0050] 本发明实施例提供的智能光网络中保护业务的恢复装置工作原理如图3所示: [0050] Recovery works intelligent optical network device according to an embodiment of the present invention shown in Figure 3 the protection service:

[0051] 控制平面102在建立带保护属性业务时,为业务端ロ分配一工作端ロ、一保护端ロ,并按照端ロ在传送平面的创建保护单元103。 [0051] In establishing the control plane 102 with protection attributes of the service, for the business end of the working end of a dispensing ro ro, ro a protecting end, and in accordance with the end ro create a transport plane of the protection unit 103.

[0052] 当控制平面102的业务处于非激活状态时,保护单元103处于冻结状态;当业务处于激活状态时,保护单元103处于解除冻结状态。 [0052] When the control plane 102 of the service is in an inactive state, the protection unit 103 in a frozen state; when the service is activated, the freeze protection unit 103 is in a released state.

[0053] 控制平面102的业务与保护单元103共用相同的检测单元101,由控制平面102控制检测单元101的工作状态; [0053] The control traffic detection and protection unit of the same unit 101,103 common plane 102, 102 controls the operation state detection unit 101 by the control plane;

[0054] 检测单元101工作状态包括打开监视、取消监视;在打开监视状态下,检测单元101主动上报告警产生和告警消失消息,并且根据检测状态对查询进行应答;在取消监视状态下,主动上报告警消失消息,并且对于查询只应答告警消失消息。 [0054] The operation state detection unit 101 includes a monitoring opening, unmonitor; monitoring in the open state, the detection unit 101 and an alarm is reported to generate an alarm message disappears, and a query response according to the detected state; monitor state is canceled, the active reports the alarm message disappears, and the query is only answer for alarm messages disappear.

[0055] 智能光网络中保护业务的恢复装置可以包括多个检测単元101,如工作端口和保护端ロ各具有了独立的检测单元101。 [0055] recovery means intelligent optical network protection service may include a plurality of detection radiolabeling element 101, such as a working port and each having a protecting end ro independent detection unit 101.

[0056] 当工作端口和/或保护端ロ的检测单元101上报告警产生后,首先触发保护単元103工作,执行业务的倒换。 [0056] When the work port and / or the protecting end ro detection unit 101 reports an alarm is generated, the trigger 103 is first protected by radiolabeling work element performing switching operations. 然后触发控制平面102启动业务的重路由,重新选择ー个新的工作/保护端ロ,并建立路径;建立成功后将重新选择的工作端口和保护端ロ更新给保护单元103 ; And triggers the control plane 102 starts rerouting traffic, re-select a new job ー / ro terminal protection, and to establish a path; after a successful re-establishment of a selected operating port and to protect the end ro update protection unit 103;

[0057] 在业务启动重路由恢复时,需要同时取消业务原有工作端口和/或保护端ロ的告警监视;在重路由恢复完成后,重新监视更新后的工作端口和/或保护端ロ。 [0057] When the business started rerouting recovery, we need to cancel the original business working port and / or protection of end ro alarm monitoring; after after rerouting recovery is complete, re-updating the monitoring port and / or protection end ro.

·[0058] 在保护单元103更新过程中,需要控制平面102控制保护单元103顺序进行如下操作: * [0058] In the protection unit 103 during the update process, the control plane needs protection unit 102 controls 103 sequentially perform the following operations:

[0059] I、冻结保护单元; [0059] I, freeze protection unit;

[0060] 2、更新保护单元的工作端口和/或保护端ロ; [0060] 2, to update port protection and / or protection of the ro-end unit;

[0061] 3、解除冻结保护单元,并重新检测更新后的工作端口和/或保护端ロ; [0061] 3, unfreeze protection unit, and retested working port and / or updated ro protecting end;

[0062] 4、当前工作和保护端ロ状态,执行保护动作。 [0062] 4, working and protection side ro current state, perform a protection action.

[0063] 当控制平面102删除业务后,需要同时删除传送平面上的保护单元103,并且同时将业务的工作和保护端ロ取消监视。 [0063] When the deletion of a service control plane 102, need to remove the protection unit 103 on the transport plane, and at the same end of the working and protection traffic ro Unmonitor.

[0064] 下面结合附图,对本发明的实施例ニ进行说明。 [0064] below with the accompanying drawings, embodiments of the present invention will be described ni.

[0065] 本发明实施例提供了ー种智能光网络中保护业务的恢复方法,使用该方法在WSON中完成保护业务的流程如图4所示,包括: [0065] Example provides a recovery method ー kinds of intelligent optical network protection service of the present invention, the method used in protection services WSON completed in Scheme 4, comprising:

[0066] 步骤401、监视ー工作端口和一保护端ロ构成的倒换恢复保护组; [0066] Step 401, a working port and a monitor ー ro WTR protecting end protection group consisting of;

[0067] 本发明实施例中,一工作端口和一保护端ロ构成ー个倒换恢复保护组,工作端ロ对应工作路径,保护端ロ对应保护路径。 Embodiment [0067] of the present invention, a working port and a protecting end ro ー constituting a WTR protection groups, corresponding to the working end of the working path ro, ro protect the end corresponding to the protection path.

[0068] 步骤402、在所述倒换恢复保护组中的端ロ发生故障时,触发启动业务的重路由; [0068] Step 402, the group recovery protection switching ro end fault occurs, the trigger starts rerouting traffic;

[0069] 本步骤中,在倒换恢复保护组的工作端ロ故障时,将故障的工作端ロ由所述倒换恢复保护组移除,并取消对该倒换恢复保护组的监视;在倒换恢复保护组的工作端ロ与保护端ロ均故障时,将故障的保护端ロ由所述倒换恢复保护组移除,并取消对该倒换恢复保护组的监视。 [0069] In this step, the protective group when the WTR working end fault ro, ro working end failure recovery protection switching by the removal group, and the switching unmonitor recovery protection group; recovery protection switching in when working end groups are ro ro and the end fault protection, fault protection ro by the end of the recovery switching the protection group is removed, and the WTR unmonitor protection groups.

[0070] 步骤403、选择一新的端ロ,使用该新的端ロ建立路径; [0070] Step 403 to select a new end-ro, ro end use of the new path is established;

[0071] 步骤404、将所述新的端ロ替换故障的端ロ,更新至所述倒换恢复保护组; [0071] Step 404, the new end-ro ro replace a failed terminal, to update the WTR protection group;

[0072] 本步骤中,将一新的端ロ替换步骤402中自该倒换恢复保护组移除的端ロ,更新至该倒换恢复保护组中。 [0072] In this step, a new end of the ro replacement step in the protection group from the WTR ro removable end 402, to update the WTR protection group. 在用新的端ロ作为新的保护端ロ吋,由于此种情况下工作端ロ及保护端ロ均故障,故在将该新的端ロ更新至保护组后,需要将该倒换恢复保护组的业务数据倒换至该新的端ロ对应的路径上。 After the end of a new protective ro ro inch with a new terminal, since in this case the working end and protect the end ro ro average failure, so in the new client update ro to a protection group, the protective group requires the WTR traffic data is switched to the path corresponding to the new end-ro.
