具体实施方式
为使本领域的技术人员更好地理解本公开的技术方案，下面结 合附图对本公开提供的网络管理方法、网元、计算机可读介质进行详细描述。
在下文中将参考附图更充分地描述示例实施例，但是所述示例实施例可以以不同形式来体现且不应当被解释为限于本文阐述的实施例。反之，提供这些实施例的目的在于使本公开透彻和完整，并将使本领域技术人员充分理解本公开的范围。
在不冲突的情况下，本公开各实施例及实施例中的各特征可相互组合。
如本文所使用的，术语“和/或”包括一个或多个相关列举条目的任何和所有组合。
本文所使用的术语仅用于描述特定实施例，且不意欲限制本公开。如本文所使用的，单数形式“一个”和“该”也意欲包括复数形式，除非上下文另外清楚指出。还将理解的是，当本说明书中使用术语“包括”和/或“由……制成”时，指定存在所述特征、整体、步骤、操作、元件和/或组件，但不排除存在或添加一个或多个其它特征、整体、步骤、操作、元件、组件和/或其群组。
除非另外限定，否则本文所用的所有术语(包括技术和科学术语)的含义与本领域普通技术人员通常理解的含义相同。还将理解，诸如那些在常用字典中限定的那些术语应当被解释为具有与其在相关技术以及本公开的背景下的含义一致的含义，且将不解释为具有理想化或过度形式上的含义，除非本文明确如此限定。
在密集型光波复用(DWDM，Dense Wavelength Division Multiplexing)光网络中，承载业务信号的OCH常需要穿越一个或多个OMS、一个或多个OTS等光元素，在这些光元素中的网元都不会下路，因此无法将向各个网元下发控制、管理指令的信令网定义成随路的网络。在一些相关技术中，在每个光纤中独立出一个光监控通道(OSC，Optical Supervisory Channel)作为下发控制、管理指令的信令通道。在又一些相关技术中，使用业务信号中的通用通信通道(GCC，General Communication Channel)开销组成下发控制、管理指令的信令网。在上述相关技术中，要使光网络中的网元为了执行控 制、管理功能而相互通信，需要先对各个网元执行信令网的配置，使得网元之间交互的信令可达，同时使各个网元知道相互之间的关联关系，并根据该关联关系实现控制、管理的协议交互。
基于上述相关技术，在对光网络中的OCH、OMS、OTS等跨越多个网元的光元素进行控制和管理时，需要为光元素的控制、管理过程独立配置信令方式，而配置光元素中的各个网元的关联关系的配置过程较为复杂，随着光网络规模的增大，配置过程会变得更加复杂，容易遗漏或出错。
DWDM光网络专门定义了自动交换光网络(ASON，Automatically Switched Optical Network)控制层、软件定义网络(SDN，Software Defined Network)控制层，但也仅实现了OCH层的连接建立、删除、恢复等功能，还无法实现对DWDM光网络中OMS、OTS等的控制、管理。一些厂家借助网管通过点到点与设备通信的方式实现对DWDM光网络中OMS、OTS等的控制、管理，但会占用大量的管理资源，而且一旦网管脱管功能将会失效。
因此，提升对光元素的控制和管理的效率成为亟待解决的问题。

为了使本领域技术人员能够更清楚地理解本公开实施例提供的技术方案，下面通过具体的示例，对本公开实施例提供的技术方案进行详细说明。
示例一
图8所示的DWDM网络模型包括三个网元(NE，Net Element)，即，NE1、NE2、NE3。实际的DWDM网络会比图8所示的DWDM网络模型更复杂，具体来说，实际的DWDM网络的拓扑结构和网元数量都会比图8所示的DWDM网络模型更加复杂。图8所示的DWDM网络模型不失一般性的作为实际中DWDM网络的抽象。
在NE1中，包括OCH业务的源端光转换单元(OTU，Optical Transform Unit)单板OTUA，波长选择开关(WSS，Wavelength Selective Switching)单板WSS11，光放大器(OA，Optical Amplifier)单板，即，光功率放大器OBA。
在NE2中，包括承载OTS光元素的OA单板，即，光线路放大器OLA。
在NE3中，包括OCH业务的宿端OTU单板OTUZ，WSS单板WSS22，OA单板，即，光前置放大器OPA。
以上板卡和网元在光网络的组织过程中，形成一个光通道连接OCH1、一个光复用段连接OMS1和两个光传输段连接OTS1和OTS2，OCH1、OMS1、OTS1、OTS2都可以作为本示例中的待管理光元素。在 一些可选实施方式中，整个系统通过管理单元(manager)进行管理。
本示例中，DWDM网络管理和控制流程包括以下步骤11至14。
步骤11，将待管理光元素归集到目标OCH。
步骤12，通过目标OCH的入口网元将对待管理光元素进行管理的控制信息以低频信号(即，随路控制信号)的方式调制加载到目标OCH中。
步骤13，目标OCH中待管理光元素在本地网元解析目标OCH中的低频信号，提取控制信息，获得控制信息中控制指令指定的协议类型、计算单元的地址信息。
步骤14，按照控制信息中计算单元的地址信息，根据控制指令指定的协议类型要求完成管理和控制所需的交互与控制响应。
在一种可选实施方式中，使用最近距离原则实现OCH的归集，例如，按照待管理光元素的发端网元距离OCH的入口网元距离(跳数)最近的原则完成OCH的归集。例如，待管理光元素可以承载n条OCH，则选择这n条OCH的入口网元距离该待管理光元素的发端网元距离最近的OCH作为目标OCH。
在图8所示的DWDM网络模型中，OTS1、OTS2、OMS1都归集到OCH1。在对光元素OTS1、OTS2、OMS1执行控制和管理时，都在OCH1的入口网元NE1中在OCH1上加载随路控制信号。
示例二
本示例中，光网络中光纤衰减的测量包括以下步骤21至25。
步骤21，在待测量的光纤承载的OCH中选择一个OCH作为目标OCH。
步骤22，在目标OCH的入口网元以低频信号的方式在目标OCH上调制加载随路控制信号，携带的控制信息包括光纤衰减测量指令、测量标识(即，关联标识)、衰减计算单元在信令网中注册的IP地址。
步骤23，光纤入纤、出纤所在的网元解析目标OCH中低频信号携带的光纤衰减测量指令，分别测量入纤光功率与出纤光功率。
步骤24，光纤入纤、出纤所在的网元将测量得到的入纤光功率、 出纤光功率、本地光纤信息与低频信号中解析到的测量标识一起通过非随路信令网发送到低频信号中指定的衰减计算单元的IP地址。
步骤25，衰减计算单元收到光纤入纤、出纤所在的网元发送的测量结果和测量标识计算光纤衰减量，并将计算的结果关联到光纤入纤、出纤所在的网元发送测量结果时发送的光纤信息，完成衰减量与光纤的关联。
在图8所示的DWDM网络模型中，需要测量网元NE2到网元NE3之间一段光纤的衰减量。该光纤所处的光传输段OTS2被归集到光通道OCH1。当光传输段(光纤)OTS2已经被归集到OCH1后，管理单元(manager)触发光纤衰减测量控制和管理要求后的协议过程包括：当管理单元触发光纤衰减测量的协议过程后，光通道OCH1的入口网元(即，网元NE1)先将需要执行光纤衰减测量的协议类型、测量标识和计算单元在非随路的信令网中注册的IP地址一起通过低频信号加载到光通道OCH1上。在本示例中，指定网元NE1作为光纤衰减计算单元，选择光通道OCH1标识与光纤入口网元NE1标识作为测量标识。因此，加载到光通道OCH1中的控制指令可以表示如下：光纤衰减测量控制指令(即，指定协议类型)+OCH1标识+NE2标识+NE1的IP地址。
光通道OCH1在传递的过程中会经过OTS2的发端网元NE2和收端网元NE3，网元NE2和NE3解析经过本地的光通道中的低频信号时将提取得到加载在光通道OCH1上的光纤衰减测量控制指令。网元NE2和NE3提取到光纤衰减测量控制指令后将分别完成所需的光功率测量：网元NE2完成光纤入纤功率测量，网元NE3完成光纤出纤功率测量，并且在完成测量后将光功率测量结果与测量标识和本地光纤信息一起发送回信令中指定IP地址的网元NE1。网元NE1收到网元NE2和NE3回传得测量结果后，根据测量标识确认两个回应属于同一光纤测量，基于光纤衰减等于光纤入纤功率减出纤功率的基本原理计算得到光纤衰减量，将计算得到的光纤衰减量关联到网元NE2和NE3回传的本地光纤信息。上述测量协议过程将会在网元NE1、NE2和NE3没有网管参与的情况下独立完成，并完成光纤衰减的实时测量。
示例三
本示例中，复用段OMS1的OSNR衰减测量方法包括以下步骤31至35。
步骤31，在待测量的光纤承载的OCH中选择一个OCH作为目标OCH。
步骤32，在目标OCH的入口网元以低频信号的方式在目标OCH上调制加载随路控制信号，携带的控制信息包括光复用段测量指令、测量标识(即，关联标识)、OSNR计算单元在信令网中注册的IP地址。
步骤33，光纤入纤、出纤所在的网元解析目标OCH中低频信号携带的OSNR测量指令，分别测量入纤光谱与出纤光谱。
步骤34，光纤入纤、出纤所在的网元将测量得到的入纤光谱、出纤光谱、本地光复用段与低频信号中解析到的测量标识一起通过非随路信令网发送到低频信号中指定的OSNR计算单元的IP地址。
步骤35，OSNR计算单元收到光纤入纤、出纤所在的网元发送的测量结果和测量标识计算OSNR，并将计算的结果关联到光纤入纤、出纤所在的网元发送测量结果时发送的光复用段信息，完成OSNR与光复用段的关联。
在图8所示的DWDM网络模型中，需要测量网元NE1到NE3之间光复用段OMS1的OSNR。光复用段OMS1被归集到光通道OCH1。当光复用段OMS1已经被归集到OCH1后，管理单元(manager)触发OSNR测量控制和管理要求后的协议过程包括：当管理单元触发OSNR测量的协议过程后，光通道OCH1的入口网元NE1先将需要执行OSNR测量的协议类型、测量标识和计算单元在非随路的信令网中注册的IP地址一起通过低频信号加载到光通道OCH1上。在本示例中，指定光通道OCH1的入口所在网元NE1作为光复用段OMS1的OSNR计算单元，选择光通道OCH1标识与光复用段OMS1入纤所在网元NE1标识作为测量标识。因此加载到光通道OCH1中的控制指令可以表示如下：OSNR测量指令(即，指定协议类型)+OCH1标识+NE1标识+NE1的IP地址。
光通道OCH1在传递的过程中会经过光复用段OMS1的收端网元NE1和发端网元NE3，网元NE1和NE3解析经过本地的光通道中的低频信号时将提取得到加载在光通道OCH1上的OSNR测量控制指令。网元NE1和NE3提取到OSNR测量控制指令后将分别完成所需的光谱测量：网元NE1完成光纤入纤光谱测量，网元NE3完成光纤出纤光谱测量，并且在完成测量后将光谱测量结果与测量标识和光复用段OMS1本地信息一起发送回信令中指定IP地址的网元，在本示例中是网元NE1。网元NE1收到网元NE1和NE3回传的光谱数据后，根据测量标识确认两个回应属于同一OSNR测量，基于OSNR计算的一般原理计算得到OSNR，将计算得到的OSNR关联到网元NE1和NE3回传的光复用段OMS1本地信息。上面的测量协议过程将会在网元NE1和NE3没有网管参与的情况下独立完成，并完成OSNR的实时测量。在本示例中，光复用段OMS 1入纤网元同时也是光通道OCH1入口网元，在实际实施的过程中可能并不需要存在本地的测量信令传递与解析，不失一般性这种传递和解析是存在的，本实施例仅用于表达了这种特殊情况的存在。
示例四
本示例中，光通道OCH1追踪方法具体实施协议过程包括以下步骤41至43。
步骤41，在待追踪的OCH的入口以低频信号的方式在OCH上调制加载OCH追踪指令、追踪标识、OCH追踪计算单元在信令网中注册的IP地址。
步骤42，OCH经过的各网元解析OCH中低频信号携带的OCH追踪指令后，将本地解析指令的板卡、端口信息和本地网元信息与收到的追踪标识一起通过非随路信令网发送到低频信号中指定的IP地址。
步骤43，IP地址所在的计算单元收到网元中各网元发送来的本地网元、板卡、端口信息基于追踪标识排序完成光通道追踪。
在图8所示的DWDM网络模型中需要执行光通道OCH1的追踪过程。因为需要执行控制和管理的光元素本身就是一个OCH，因此在执行通道归集的过程中直接将待控制和管理的OCH归集到自身。待追踪 的这条OCH的入口网元为光通道OCH1的入口网元NE1。当OCH已经被归集到光通道OCH1后，管理单元(manager)触发OCH追踪的控制和管理要求后的协议过程包括：当管理单元触发OCH追踪的协议过程后，光通道OCH1的入口网元NE1先将需要执行OCH追踪的协议类型、追踪标识和计算单元在非随路的信令网中注册的IP地址一起通过低频信号加载到光通道OCH1上。在本示例中，指定OCH的入口所在网元NE1作为OCH追踪的计算单元，选择光通道OCH1标识作为追踪标识。因此加载到光通道OCH1中的控制指令可以表示如下：OCH追踪指令(即，指定协议类型)+OCH1标识+NE1的IP地址。
在本实施例中，根据OCH追踪的协议要求，光通道OCH1经过的所有网元，在具备OCH低频信号解析能力的所有板卡上解析到OCH追踪的控制指令后，都将解析到的控制指令中的追踪标识与本地网元、板卡、端口和追踪标识一起发送到网元NE1。在图8所示的DWDM网络模型中的所有板卡单元OTUA、WSS11、OBA、OLA、OPA、WSS22、OTUZ都解析到了光通道OCH1的OCH追踪指令。网元NE1将OTUA、WSS11、OBA检测到追踪指令的端口连同光通道OCH1标识、自身网元标识一起发送到网元NE1；网元NE2将OLA检测到追踪指令的端口连同光通道OCH1标识、自身网元标识一起发送到网元NE1；网元NE3将OPA、WSS22、OTUZ检测到追踪指令的端口连同光通道OCH1标识、自身网元标识一起发送到网元NE1。网元NE1的处理单元接收到这些回应信息后，将所有的网元、端口标识进行排序并归属到光通道OCH1标识下完成光通道OCH1标识的追踪过程。
