WDM(Wavelength Division Multiplexing，波分复用)系统开局前需要对系统进行规划、设计，根据用户承载的业务要求，选择光器件参数，光性能指标，以满足当系统器件寿命终了时，业务依然能正常传输的目的。系统设计时，需要权衡成本、光性能指标、传输距离、器件的损耗等因素，来选择发送机、接受机类型、放大器类型、个数，光缆类型，设计合适的光性能指标，对光性能的指标留出一定的富裕度，以适应外界环境的劣化后，业务可以正常传输，因此WDM系统设计过程非常复杂，需要专业的领域知识，即使经过仔细设计的系统也只是一种建议方案，不一定满足现网要求，还需要经过长时间的调整，最终才能满足通信要求。

步骤408，将设计系统的影响因素作为目标案例的输入，案例推理开始。
步骤410，设定相似度阈值，设定输入各个特征的权重值。
步骤412，根据输入信息在数据库进行案例检索。
步骤414，计算目标案例输入和数据库案例输入的相似度，设目标案例的影响设计因素输入为D，D的描述特征为F＝{fi}(i＝1,...,8)，其中传输距离f1、跨段数f2、传输段损耗余量f3、满配波长数f4、波长间隔f5、单波速率f6、波段f7、拓扑形式f8，其中，拓扑形式f8为枚举类型，包括点到点、环网、网状网等；设计案例库中的案例Dk描述特征Fk＝{fi,k}(k＝1,2,...,K)，K为设计案例库中的案例数量。

Figure PCTCN2017086395-appb-000001
其中，Wi表示案例特征权值，Sim(fi，fi,k)为输入案例的第i个描述特征fi和第k条案例描述特征fi,k的相似度，采用如下公式计算，定义为：
当i＝1,2…7时；
sim(fi,fi,k)＝1-|fi-fi,k|/max(fi,fi,k)

Figure PCTCN2017086395-appb-000002
根据计算出的相似度，与阈值进行比较，得到大于阈值的备选案例集合。
步骤416，判断是否存在大于阈值的备选案例集合，存在，则执行步骤418，不存在则执行步骤426.
步骤418，获取备选案例集合，作为优先案例集合。
步骤420，对优选案例集合进行遍历，根据相似度由大到小的顺序，对每个案例进行重用和修正；将当前案例结果直接设置为设计环境，检查收端的误码率是否满足通道接收端最低要求，满足则不需要修正，直接使用该案例的结果作为设计结果，如果不满足则需要反复修正、验证，直至满足通道接收端的误码率最低要求，如果修正到器件参数极限仍无法满足，则遍历下一个案例，继续上述重用和修正过程，具体步骤在下文进行描述。

现对步骤420进行描述，本实施例提供的基于案例推理的WDM系统设计方法中的案例重用和修正步骤包括：
步骤502，开始。
步骤504，将案例优选获得的案例集按照相似度由大到小的顺序，顺序遍历重用和修正每个案例。
步骤506，将当前遍历到的案例导入到网管，形成网元、单板、连纤、路径等可管理的资源。
步骤508，划分修正单元：将复用段和其承载的多个通道层作为修正 单元，将复用段中的执行器，如放大器及衰减器等，作为复用段修正元件，通道层的可调通道衰减的单板器件作为通道层修正元件。
步骤510，查询每个修正单元中的多个通道层接收端的误码率性能。
步骤512，针对修正单元中的每个通道层，判断其接收端误码率是否满足最低误码率要求，满足，则重用该案例的输出设计结果，将输入和输出设计结果组成最优案例，继续步骤522。
步骤514，修正案例修正单元。
修正算法如下：假设复用段OMS，包含了N条通道层OCHj(j＝1…N)，OMS有M个修正元件OAi(i＝1…M)，OMS包含H个光纤段Fiber h(h＝1…H)，OCHj有L个修正单元WSUs(s＝1…L)。
对于OMS，修正目标是减少信号能力损耗，增加光信噪比，从而达到减少误码率，修正方式是放大器件增益抵消掉光纤的衰减，采用如下公式，定义为：
Figure PCTCN2017086395-appb-000003
对于OCH，修正目标是各通道功率均衡，接收端误码率满足最低要求，修正方式是调整前L-1个WSUs的衰减量，使得各光通道输出的光功率均衡，调整第L个接收端业务板前的WSUs，使得通道对应输出的光功率满足业务板输入光功率的标准值，如果接收端误码率过大，优先调整前第i个WSUs，按每次减少0.5dB的步长来调整，为稳定接收端的光功率，增大接收端前面的第L个WSUs0.5dB衰减，从而增大光信噪比，减少误码率，如果第1个WSUs衰减量已经调大最大，则往下顺序调整第i+1个WSUs。
步骤516，判断根据修正算法得到的修正元件调整量是否超过参数的范围，没超过，则继续执行步骤512，超过，则执行步骤518。
步骤518，判断当前优选的案例是否是优选案例集中的最后一条案例，否，则继续执行步骤506，是，则执行步骤522。
步骤522，结束。
在实际应用中，上述方法和装置可以通过软件编程来实现，改进方便，而且操作性强，相对于现有技术而言，能够更有效、更准确的根据影响设计因素设计出最优的WDM系统。
由此便可以实现上网等业务流量，在乱序情况的动态保序。
