具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本发明的说明，其本身没有特定的意义。因此，“模块”、“部件”或“单元”可以混合地使用。
如图1所示，为实现本发明各个实施例一个可选的功率管理子系统的分布示意图。功率管理子系统将密集型光波复用(Dense Wavelength Division Multiplexing，DWDM)系统分解为各个管理单元，分别加以管理和优化，包括网元管理单元101、网元(Network Element，NE)1、NE2、NE3。在图1中，功率管理域开始于首网元(Network Element，NE)1最后一个合波类单板之后的最后光放大板(OA)的输出端口，终结于尾网元(NE3)的第一个分波类单板之前的最后光放大板的输出端口。一个方向是一条链路，将一个光放大板作为一个功率监测点，则链路上相邻的两个功率监测点之间的区域作为一个分布式自动功率优化(Automatic Power Optimization，APO)组，APO组中包含功率监测单元(OA)和功率调节单元(SFP VOA)，从而将图1中的NE1中第一OA101的输出到NE2中第二OA102的输出构成第一APO组10，NE2中第二OA102的输出到NE3中第三OA103的输出构成第二APO组20。不同的APO组归属于不同的功率控制器单元，功率控制器单元对归属于它的APO组执行功率监测与调节，功率控制单元之间通过网元间的监控信道传递的管理信息实现整条链路上下游的协作控制。
网元管理单元101，用于发送APO链路配置报文，将链路配置报文发送给链路经过的所有网元的APO控制器。
网元可以包括：功率控制单元102、功率监测单元103以及功率调节单元104，其中：
功率控制单元102运行在各个网元的主控单板上，用于控制本网元的功率调节执行功率监测和调节，也用于控制整条链路上跨多个网元的功率控制器协同工作。
功率监测单元103用于APO控制器查询监测的性能，得到监测量，即功率管理算法的输入变量。
功率调节单元104，用于接收控制器下发的调节命令，执行功率调节。
基于图1中的APO部署分布场景图，提出本发明的各个实施例，本领域技术人员可以理解的是，本发明并不限制图1中各个系统及单元的数量、分布方式等。
如图2所示，为本发明第一实施例提供的监控信道控制方法，应用于波分系统，在图2中，所述监控信道控制方法包括以下步骤：
步骤210，检测本网元与相邻的上游网元之间的监控信道是否中断；若是，则进入步骤220；
步骤220，向调节控制节点下发衰减调节回退命令，以使所述调节控制节点根据其所在的位置触发执行功率回退，其中，所述调节控制节点位于所述本网元或者所述上游网元。
具体的，监控信道采用专用波长(1510/1550nm)发送。通过检测相邻两个网元的通信是否正常来确定执行调整后的功率是否会影响到监控信道。当判断相邻两个网元之间的监控信道中断时，则说明之前的调节动作不恰当，需要执行调节回退，则向功率调节节点下发衰减调节回退命令，并根据该功率调节节点的位置，以触发本网元执行功率回退，或者触发上游网元执行功率回退，以恢复监控信道。相反地，当判断相邻两个网元之间的监控信道没有中断时，则说明之前的条件动作是恰当的，不需要执行调节回退，从而流程结束。
如图3所示，步骤210具体包括以下步骤：
步骤310，向上游网元发送通信链路检测消息；
步骤320，当在预设时间内没有收到所述上游网元响应所述通信链路检测消息的应答消息时，则所述监控信道中断。
具体的，接收功率调整的应答消息，发起监控信道检测，给上游节点发送通信链路检测消息。判断在预设的时间内，是否收到上游网元装置发送的应答消息。当超过预设时间时，没有收到上游网元装置响应通信链路检测消息的应答消息，则表示监控信道出现中断，需要执行调节回退。相反地，当未到预设时间时，就收到上游网元装置响应通信链路检测消息的应答消息，则表示监控信道没有出现中断，不需要执行调节回退。
本发明的监控信道控制方法适用于调节控制节点在同一网元的场景，也适用于调节控制节点在不同网元的场景。本发明的监控信道控制方法还包括：
判断调节控制节点位于本网元还是上游网元。
如图4所示，若调节控制节点位于本网元，例如，图1中，第二APO组20的功率调节单元104及其归属的功率控制单元102均位于NE3，则所述监控信道控制方法还包括：
步骤410，接收网元管理单元发送的功率调节链路配置，启动异常监测；
步骤420，定时下发功率基准值更新命令；
步骤430，根据所述功率基准值更新命令，实时监测输入功率与基准值的差值；
步骤440，当出现功率越限时，则通过网元间的监控信道获取功率调节许可令牌；
步骤450，执行功率调节。
具体的，网元管理单元(如图1中的网元管理单元101)发送APO链路配置报文，该链路配置报文发送给链路经过的所有网元的APO控制器。当接收网元管理单元发送的功率调节链路配置，则启动异常监测。定时下发功率基准值更新命令，根据该命令，实时监测输入功率与基准值的差值，如果出现越限，则上报功率波动越限。如果没有出现越限，则说明当前节点属于正常节点。
当出现越限时，通过网元间的监控信道申请调节许可令牌，当获取本链路的调节令牌后，下发调节命令，并执行功率调节，当调节成功时，则产生功率调整的应答消息，以发起监控信道检测。
如图5所示，若调节控制节点位于上游网元，例如，图1中，第一APO组10的功率调节单元104位于NE1，归属该功率调节单元104的功率控制单元102位于NE2，则所述监控信道控制方法还包括：
步骤510，接收网元管理单元发送的功率调节链路配置，启动异常监测；
步骤520，定时下发功率基准值更新命令；
步骤530，根据所述功率基准值更新命令，实时监测输入功率与基准值的差值；
步骤540，当出现功率越限时，则通过网元间的监控信道获取功率调节许可令牌；
步骤550，向上游网元发送功率衰减调节命令；
步骤560，启动等待通信链路检测消息的定时器，以通过上游网元执行功率调节。
具体的，网元管理单元(如图1中的网元管理单元101)发送APO链路配置报文，该链路配置报文发送给链路经过的所有网元的APO控制器。当接收网元管理单元发送的功率调节链路配置，则启动异常监测。下发功率基准值更新命令，根据该命令，实时监测输入功率与基准值的差值，如果出现越限，则上报功率波动越限。如果没有出现越限，则说明当前节点属于正常节点。
当出现越限时，通过网元间的监控信道申请调节许可令牌，当获取本链路的调节令牌后，由于功率调节单元位于上游网元(图1中第一APO组10的功率调节单元104位于NE1)，则将衰减调节命令发送给上游网元(NE1)的功率控制单元102，同时启动等待 通信链路检测消息的定时器，以通过上游网元的功率控制单元102执行功率调节，当调节成功时，则产生功率调整的应答消息，以发起监控信道检测。
本发明提供的监控信道控制方法，当功率调节之后，通过检测相邻两个网元之间的监控信道中断时，下发衰减调节回退命令，并根据该回退命令，执行功率回退，以恢复监控信道，实现了在功率调节后，自动发起监控信道检测，如果检测到监控信道中断，则监控信道在无人干涉的情况下能够自动恢复，确保监控信道保持畅通，以避免网元间通信中断或网元脱管。
