具体实施方式
下面通过具体实施方式结合附图对本申请作进一步详细说明。
实施例一：
请参见图1所示，本实施例提供的光通讯网络中的业务控制方法，在断纤场景下收集受损业务，对收集的受损业务进行光层调度，其过程请参见图1所示，包括以下步骤：
步骤S101：在断纤时获取受损业务；
步骤S102：确定受损业务所在的业务路径；
步骤S103：为业务路径查找目标替换路径；
步骤S104：将所述受损业务的业务路径切换到所述目标替换路径上。
通过上述过程可在断纤时针对受损业务进行及时地光层调度，因此可以使得受损业务得到快速有效的恢复从而满足网络的生存性保护要求，为网络的规划假设提供保障。
可选地，在本实施例中，上述步骤103中，为业务路径查找目标替换路径包括：
确定业务路径上的待替换路段；
为待替换路段查找目标替换路段。
在本实施例中，在确定业务路径上的待替换路段时，可以采用尽量复用和尽量分离两个原则。
采用尽量复用原则时，可将业务路径上受损的路段作为待替换路段；或，先将业务路径上受损的路段作为待替换路段，在为该待替换路段查找目标替换路径失败时，再逐渐向业务路径上未受损的路段扩展，直到将组成业务路径的所有路段都确定为待替换路段；或，先将业务路径上受损的路段作为待替换路段，在为该待替换路段查找目标替换路径失败时，直接将组成业务路径的所有路段都确定为待替换路段。
采用尽量分离原则时，可直接将组成业务路径的所有路段都确定为待替换路段。
可选地，上述步骤104中，将所述受损业务的业务路径切换到所述目标替换路径上包括：
为目标替换路段分配与待替换路段相同的波长；如果为目标替换路段分配与待替换路段相同的波长失败，则为目标替换路段分配与待替换路段不同的波长，此时则需顺序尝试异波。
可选地，所述方法还包括：在为业务路径查找目标替换路径失败或将所述受损业务的业务路径切换到所述目标替换路径上失败时，也即进行光层调度失败时，本实施例还可对该受损业务进行电层调度，此时则需要为该受损业务新增路径，将该受损业务的业务路径切换到新增路径上。此时需要在节点上新增单板端口。
综上可知，本实施例在断纤时针对受损业务可以先进行光层调度，针对光层调度失败的受损业务还可进一步通过电层调度进行业务恢复。
下面以集合的形式说明本实施例提供的方案，请参见图2所示，图2所示流程包括以下步骤：
步骤S201：针对断纤场景，收集所有受损业务，得到受损业务集合TS；
步骤S202：对受损业务进行光层调度，并收集光层调度成功的业务， 得到光层调度成功的业务集合TS1；
步骤S203：从受损业务集合TS中删除光层调度成功的业务集合TS1，得到光层调度失败的受损业务集合TS2；
步骤S204：对光层调度失败的受损业务集合TS2中的受损业务进行电层调度；
步骤S205：结束断纤规划。
实施例二：
请参见图3所示，本实施例提供了一种光通讯网络中的业务控制装置，包括：
受损业务获取模块1，设置为获取断纤时的受损业务；
业务路径确定模块2，设置为确定受损业务所在的业务路径；
第一控制模块3，设置为：为业务路径查找目标替换路径；将所述受损业务的业务路径切换到所述目标替换路径上。
第一控制模块3包括确定子模块、处理子模块；
确定子模块设置为确定业务路径上的待替换路段，包括：
采用尽量复用原则，将业务路径上受损的路段作为待替换路段；或，先将业务路径上受损的路段作为待替换路段，在为该待替换路段查找目标替换路径失败时，再逐渐向业务路径上未受损的路段扩展，直到将组成业务路径的所有路段都确定为待替换路段；或，先将业务路径上受损的路段作为待替换路段，在为该待替换路段查找目标替换路径失败时，直接将组成业务路径的所有路段都确定为待替换路段。
采用尽量分离原则，直接将组成业务路径的所有路段都确定为待替换路段。
处理子模块设置为为待替换路段查找目标替换路段。
可选地，本实施例的光通讯网络中的业务控制装置还包括路径增加模块4，用于设置为在第一控制模块3为业务路径查找目标替换路径失败，或将 所述受损业务的业务路径切换到所述目标替换路径上失败时，新增路径；也即在对受损业务进行光层调度失败时，针对该受损业务进行电层调度；
第二控制模块5，设置为将业务路径切换到新增路径上。
实施例三：
下面以一个具体的组网为例，对本发明实施例做进一步示例性说明。
请参见图4所示，实线表示光纤，虚线表示两节点之间的业务。在节点001和004之间创建一条业务，记为T(1-4)；在节点003和004之间创建一条业务，记为T(3-4)。业务T(1-4)的业务路径走001-002-003-004，业务T(3-4)的业务路径走003-004。假设在003-004光纤上，业务T(1-4)和业务T(3-4)汇聚成同一波长。业务T(1-4)所在的路径路段在001-002和002-003光纤上占同波；业务T(1-4)和业务T(3-4)的路径路段在光纤003-004上占用同波。
图5为在图4所示组网基础上，断纤场景为002-003光纤断开，如图4所示，此时的业务控制过程如下：
步骤S501：收集所有受损业务TS；
在光纤002-003受损时，业务T(1-4)的业务路径经过该光纤，业务受到影响，而业务T(3-4)的业务路径没有经过该光纤，不受影响。所以该场景下受损业务TS集合中的业务为T(1-4)；
步骤S502：对受损业务进行光层调度；
光层调度的特点是在调度过程中不会新增单板端口，该过程包括：
受损的光纤是002-003光纤，该光纤所在的FA(Forwarding Adjacent,转发邻接)段即受损FA为001-002-003。
为受损业务的业务路径寻找可替代的目标替换路径；若用户采用尽量复用策略，找替代FA时系统会尝试复用完好光纤001-002，在002,003节点寻找替代光纤，由于没有可替代的，故再扩大范围，从1,3节点寻找，可以找到可替代路径001-005-003。若用户采用尽量分离策略，系统直接从001,003节点寻找可替代路径，尽量规避受损路径的所有光纤，该拓扑图中可以找到路径001-005-003；
找到可替代路径001-005-003，由此生成业务的可替代路径为001-005-003-004。然后为该路径分配波长，只需为新找到的替代路径分配波长，先尝试和原先受损路径相同的波长，若相同的波长不可用，再顺序尝试异波。
若光层调度成功，则业务T(1-4)会调度到001-005-003-004，保存该结果。此时受损光纤已遍历完，光层调度失败的业务集合TS2为空；若光层调度失败，此时受损光纤已遍历完，光层调度失败的业务集合TS2中包含业务T(1-4)。
步骤S503：判断光层调度是否成功，如是，转至步骤S504；否则，转至步骤S505；
步骤S504：针对当前的受损业务调度完毕，转入下一个受损业务。
步骤S505：在TS2中包含业务T(1-4)时，对业务T(1-4)进行电层调度；
电层调度需要在节点新增单板端口。本实施例中，新增资源后，业务T(1-4)可能走的路径为001-005-003-004或者001-006-004；
步骤S506：针对当前的受损业务调度完毕，转入下一个受损业务。
在更复杂的网络拓扑和业务量更大的情况下，本发明实施例所描述的断纤规划方法可以在尽量节省资源的情况下，快速有效地为业务寻找恢复路径。
本发明实施例还提供一种计算机可读存储介质，所述计算机可读存储介质中存储有计算机可执行指令，所述计算机可执行指令被执行时实现光通讯网络中的业务控制方法。
