同时，应当明白，为了便于描述，附图中所示出的各个部分的尺寸并不是按照实际的比例关系绘制的。
对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为授权说明书的一部分。
在这里示出和讨论的所有示例中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它示例可以具有不同的值。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
发明人通过研究发现：DCI场景一般存在业务需求急迫、扩容增速快等特点，相关 技术对盒式波分系统的配置管理，如果采用单站法配置OMS则人工开通时间长，路由法又存在部分厂商因尺寸和板卡集成度差异导致可能需要跨网元调度板卡资源的问题，难以对多厂商盒式波分设备实现自动OMS(Optical Multiplex Section，光复用段)创建。
鉴于以上技术问题中的至少一项，本公开提供了一种光复用段创建方法和装置、网络管理系统和盒式波分设备，可以自动选择包括终端站、光放站设备在内的沿途板卡、端口资源，进行光复用段的自动创建。
图1为本公开光复用段创建方法一些实施例的示意图。优选的，本实施例可由本公开光复用段创建装置或本公开网络管理系统或本公开盒式波分设备执行。该方法可以包括步骤11和步骤12中的至少一个步骤，其中：
步骤11，选择当前网管的沿途板卡和端口资源，进行光复用段的自动创建，其中，当前网元包括终端站和光放站设备。
步骤12，在当前网元上的板卡不能满足资源要求的情况下，允许跨网元调度板卡资源。
在本公开的一些实施例中，步骤12可以包括：针对不同跨段、不同保护需求的场景，选择当前网管的沿途板卡和端口资源，进行光复用段的自动创建，其中，不同跨段包括单跨段和多跨段，不同保护需求包括光复用段保护需求和无保护需求。
本公开上述实施例可以进行跨网元板卡资源调度，本公开上述实施例采用路由法进行光复用段创建，可以自动选择包括终端站、光放站设备在内的沿途板卡和端口资源，允许跨网元调度。
在本公开的一些实施例中，所述光复用段创建方法还可以包括：根据盒式波分设备的不同板卡集成度，支持图2-图5四种OA(Optical Amplifier，光放大器)板卡类型中的至少一种，其中：
1)集成BA(Booster-Amplifier，功率放大器)和PA(Pre-Amplifier，前置放大器)的板卡，图2为本公开一些实施例中集成PA+BA的光放板卡的示意图。

4)ILA(in-Line-Amplifier，光线路放大器板卡)板卡，其中，ILA板卡含双向EDFA(Erbium Doped Fiber Amplifier，掺铒光纤放大器)。图5为本公开一些实施例中集成双向ILA的光放板卡的示意图。
本公开上述实施例能够提供跨网元自动调度板卡资源的光复用段自动创建方法，在开放解耦的多厂商光网络中，能够为不同集成度的光放板卡提供支持，可以实现板卡灵活调 度。
传统波分设备往往采用烟囱式管理，单厂商仅需要处理特定的板卡形态，而盒式波分因其开放解耦的特征，会导致需要纳管不同厂商的不同光放板卡，因实现差异往往会存在不同集成度的板卡，本公开上述实施例的调度方法可以支持不同光放板卡集成度，可以支持所有光放板卡。
本公开可以自动选择包括终端站、光放站设备在内的沿途板卡、端口资源，进行光复用段的自动创建；本公开可以实现跨网元板卡资源调度。

在本公开的一些实施例中，图7实施例的步骤703，步骤709、步骤710和步骤712为与图6实施例的单跨段创建流程不同的部分。
在本公开的一些实施例中，第一约束条件、第二约束条件和第三约束条件适应于单跨段场景和多跨段场景，即，适用于图6和图7实施例。
在本公开的一些实施例中，第一约束条件可以包括：
1、光放大器板卡包含2个功率放大器和2个前置放大器，即，OA板卡包含的EDFA数量为：BA*2，PA*2。
2、资源重复时的优先原则为：集成功率放大器和前置放大器的板卡为第一优先级，单掺铒光纤放大器为第二优先级。即，集成BA+PA的板卡优先；单EDFA次优。
3、主路径的功率放大器和前置放大器(BA+PA)、以及备路径的功率放大器和前置放大器(BA+PA)处于不同网元。由此可以提供主备路径的设备级分离能力。
在本公开的一些实施例中，第二约束条件可以包括：
1、包含一个光线路保护设备板卡(OLP板卡*1)，假设每个光线路保护设备板卡上只有一个光保护开关。
2、光线路保护设备板卡不得与主路径的功率放大器同网元。由此可以提供掉电保持能力。
在本公开的一些实施例中，第三约束条件可以包括：
1、光放大器板卡包含1个功率放大器和1个前置放大器；即，BA*1，PA*1。
2、资源重复时的优先原则为：集成功率放大器和前置放大器的板卡为第一优先级，单掺铒光纤放大器为第二优先级。即，集成BA+PA的板卡优先；单EDFA次优。
本公开上述实施例可以实现单跨和多跨、有保护和无保护场景的自动化创建光复用段。本公开上述实施例能够满足不同跨段、不同保护需求的光复用段自动化创建需求。
本公开上述实施例提供了一种应用于盒式波分系统的光复用段自动化创建方法。
本公开上述实施例提出一种光复用段自动化创建方法。本公开上述实施例可以同时适用于单跨段或多跨段场景，由盒式波分管控系统自动选择包括终端站、光放站设备在内的沿途板卡、端口资源，进行光复用段的自动创建；本公开上述实施例当网元上的板卡不能满足资源要求时，允许跨网元调度板卡资源；本公开上述实施例可以支持不同集成度的光放板卡形态。
图8为本公开光复用段创建方法另一些实施例的示意图。优选的，本实施例可由本公开光复用段创建装置或本公开网络管理系统或本公开盒式波分设备执行。该方法可以包括步骤81-步骤85中的至少一个步骤，其中：
步骤81，获取相关站点的可用网元资源。
步骤82，获取各网元的网元信息，其中，所述网元信息包括板块信息和端口可用性等信息。
步骤83，根据业务需求，按照如上述任一实施例(例如图1-图7任一实施例)所述的光复用段创建方法进行所需板块资源的调度。
步骤84，获取网元之间的连接信息。
步骤85，对调度到的板块资源进行端口级的串接，形成光复用段。
本公开上述实施例可以实现跨网元板卡资源调度。由于盒式波分设备不同于传统波分设备，其易堆叠的设计也同时带来设备体积限制，在单一网元的板卡资源受限情况下，本公开上述实施例提出跨网元板卡资源调度方法，可以将同一站点中满足可用条件的网元板卡均列入板卡资源池，进行统一调度。
图9为本公开光复用段创建装置一些实施例的示意图。如图9所示，本公开光复用段创建装置可以包括复用段创建模块91和板块调度模块92，其中：
复用段创建模块91，用于选择当前网管的沿途板卡和端口资源，进行光复用段的自动创建，其中，当前网元包括终端站和光放站设备。
板块调度模块92，用于在当前网元上的板卡不能满足资源要求的情况下，允许跨网元调度板卡资源。
在本公开的一些实施例中，光复用段创建装置可以用于根据盒式波分设备的不同板卡集成度，支持以下四种光放大器板卡类型中的至少一种：集成功率放大器和前置放大器的板卡、仅包含功率放大器的板卡、仅包含前置放大器的板卡、包含双向掺铒光纤放大器的光线路放大器板卡。
本公开上述实施例可以进行跨网元板卡资源调度，本公开上述实施例采用路由法进行光复用段创建，可以自动选择包括终端站、光放站设备在内的沿途板卡和端口资源，允许跨网元调度。
本公开上述实施例能够提供跨网元自动调度板卡资源的光复用段自动创建方法，在开放解耦的多厂商光网络中，能够为不同集成度的光放板卡提供支持，可以实现板卡灵活调度。
传统波分设备往往采用烟囱式管理，单厂商仅需要处理特定的板卡形态，而盒式波分因其开放解耦的特征，会导致需要纳管不同厂商的不同光放板卡，因实现差异往往会存在不同集成度的板卡，本公开上述实施例的调度方法可以支持不同光放板卡集成度，可以支 持所有光放板卡。
