技术领域
本申请涉及光纤通信领域，尤其涉及一种光功率值的传输方法、系统以及相关设备。
背景技术
为保证光信号在上游网络设备和下游网络设备之间的成功传输，则需要对上游网络设备和下游网络设备之间所连接的光纤进行运维，例如，对光纤的光纤衰耗进行检测等。
现有技术中，为实现对上游网络设备和下游网络设备之间所连接的光纤进行运维的目的，则需要上游网络设备将光信号从上游网络设备输出的输出功率值经由该光纤发送给下游网络设备。在上游网络设备和下游网络设备位于不同的数据通信网(data communication network，DCN)的情况下，为实现输出功率值的传输，则需要人工在上游网络设备中配置路由信息，该路由信息用于指示上游网络设备和下游网络设备之间的光纤连接关系，则上游网络设备即可基于该路由信息向该路由信息指示的下游网络设备发送输出功率值。
但是，人工配置路由信息非常繁琐，降低了获取输出功率值的效率和准确性。
发明内容
本发明实施例提供了一种光功率值的传输方法、系统以及相关设备，其用于提高获取输出功率值的效率和准确性。

基于上述所示的OMS的说明，采用本申请所提供的光功率值的传输方法的目的在于，如何在OMS跨DCN的场景下，源网络设备能够自动发现目标网络设备，进而能够实现对OMS所包括的任意相邻的两个网络设备之间所连接的光纤的运维。本申请所示的运维包括但不限于对该OMS所包括的任意相邻的两个网络设备之间所连接的光纤进行检测，以获取光纤衰耗，从而便于在光纤衰耗未劣化至导致业务传输受损前，对光纤劣化进行预警，以降低光纤劣化故障风险，以节省运维成本，提升运维效率。如图1所示的示例，通过本申请所示的方法能够检测到中间网络设备102和中间网络设备103之间所连接的光纤的光纤衰耗，从而根据该光纤衰耗判断中间网络设备102和中间网络设备103之间所连接的光纤是否劣化、出现断裂、故障或脏污等情况。本实施例对运维的说明为可选地示例，具体在本申请中不做限定，如下所示以本实施例所示的运维为检测OMS内所包括的任意相邻的两个网络设备之间所连接的光纤的光纤衰耗为例进行示例性说明。
以下结合图2所示对本实施例所提供的光功率值的传输方法的具体执行过程进行说明：
步骤201、源网络设备获取OMS链路信息。
为更好的理解本实施例所示的OMS链路信息，首先结合图3所示对本实施例所提供的源网络设备的结构进行示例性说明，其中，图3为本实施例所提供的源网络设备的一种实 施例局部结构示例图，如图3所示，本实施例所示的源网络设备包括N个波长选择开关(wavelength selective switch，WSS)，本实施例对N的具体取值不做限定，如图3所示以该N等于9为例进行示例性说明，即本实施例所示的源网络设备300包括9个WSS为例(即WSS301、WSS302至WSS309)。其中，WSS301通过光纤分别与位于不同位置处的WSS302、WSS303至WSS309连接，用于将源网络设备300光信号(例如，由源网络设备300本地产生的)向位于不同位置处的其他WSS(即WSS302、WSS303至WSS309)发送，以实现对光信号沿不同维度方向进行传输的目的。例如，若源网络设备300需要将光信号沿第一维度方向进行传输，则WSS301将光信号传输至WSS302，若源网络设备300需要将光信号沿第二维度方向进行传输，则WSS301将光信号传输至WSS303，其中，第一维度方向和第二维度方向为互不相同的两个维度方向。
可选地，该WSS301连接一个或多个业务单板，本实施例对业务单板的具体数量不做限定，该业务单板用于产生光信号。
需明确地是，本实施例以WSS301和用于将光信号从源网络设备300输出且位于不同位置处的WSS(即WSS302、WSS303至WSS309)之间通过光纤直接连接为例进行示例性说明，在其他示例中，以WSS301和WSS309为例，WSS301和WSS309之间还可连接一个或多个WSS，和/或连接在WSS301和WSS309之间的用于对光信号的能量进行放大的光放大器等器件，具体在本实施例中不做限定。
可见，通过本实施例所示的源网络设备300所包括的两个WSS，实现对光信号沿不同的维度方向的灵活调度。即图3所示的源网络设备300通过位于不同位置处的八个WSS(即WSS302、WSS303至WSS309)实现对光信号沿8个不同的维度维度方向进行传输的目的。
本实施例所示的源网络设备可存储多个OMS链路信息，不同的OMS链路信息用于指示不同的OMS，具体地，该OMS链路信息所指示的OMS均包括所述源网络设备，该OMS还包括任意相邻的两个网络设备之间的连纤关系，可见，源网络设备所包括的不同的OMS链路信息用于指示光信号沿不同的OMS进行传输的路径，为更好的理解，以下结合图4所示进行说明，其中，图4为本实施例所提供的光信号沿不同的OMS进行传输的示例图。
图4所示以源网络设备300已存储三个不同的OMS链路信息为例进行示例性说明，三个不同的OMS链路信息用于指示光信号沿不同的三个OMS(如图4所示的OMS401、OMS402以及OMS403)进行传输的路径。以OMS403为具体的示例，该OMS403包括三个网络设备，即依次通过光纤连接的源网络设备300、中间网络设备410和目标网络设备411，对源网络设备、中间网络设备以及目标网络设备的说明，具体可参见上述图1所示，具体不做赘述。可见，用于指示OMS403的OMS链路信息，用于指示光信号依次沿源网络设备300、中间网络设备410以及目标网络设备411进行传输的路径。
步骤202、源网络设备根据OMS链路信息确定第一输出端口。
所述源网络设备执行本实施例所示的方法的目的在于，对OMS所包括的任意相邻的两个网络设备之间所连接的光纤进行运维，对运维的说明，请详见上述所示，具体不做赘述。本实施例所示的源网络设备能够基于已存储的OMS链路信息实现对OMS链路信息所指示的OMS的自动运维，例如，在源网络设备已存储多个OMS链路信息的情况下，所述源网络设 备可对多个OMS链路信息轮询执行本实施例所示的方法以实现对各个OMS的运维，又如，源网络设备可周期性地对各个OMS链路信息执行本实施例所示的方法以实现对各个OMS的运维等，具体在本实施例中不做限定，例如，在其他场景下，源网络设备也可随机对多个OMS链路信息执行本实施例所示的方法以实现对各个OMS的随机运维等。
可见，本实施例所示的源网络设备无需人工输入路由信息，而是基于已存储的OMS链路信息，即可自动实现对OMS内所包括的任意相邻的两个网络设备之间所连接的光纤的运维，提高了对光纤进行运维的效率和准确性。
本实施例所示的源网络设备可根据待运维的目标OMS链路信息确定第一输出端口，其中，所述目标OMS链路信息为所述源网络设备所存储的多个OMS链路信息中的一个，且所述目标OMS链路信息用于指示待运维的目标OMS。其中，所述源网络设备通过所述第一输出端口与下游网络设备之间通过第一光纤连接，所述下游网络设备为该目标OMS所包括的与所述源网络设备连接的网络设备，为更好的理解，以下结合图4和图5所示进行示例性说明，其中，图5为本实施例所示的目标OMS所包括的相互连接的源网络设备和中间网络设备的结构示例图，以下对源网络设备确定第一输出端口的过程进行说明：
首先，源网络设备在已存储的多个OMS链路信息中确定待运维的目标OMS链路信息，例如，该目标OMS链路信息用于指示图4所示的目标OMS403。
其次，源网络设备根据目标OMS链路信息确定第一输出端口，其中，源网络设备300通过该第一输出端口与下游网络设备连接，即源网络设备300经由该第一输出端口将光信号向下游网络设备传输，以实现光信号沿目标OMS所包括的各个网络设备依次进行传输的目的。可见，该下游网络设备为目标OMS链路信息所指示的与源网络设备通过光纤直接连接的网络设备。在目标OMS为OMS403的情况下，则源网络设备300通过第一输出端口与中间网络设备410连接。
可见，在目标OMS链路信息包括中间网络设备的情况下，则该下游网络设备为与源网络设备连接的中间网络设备，在目标OMS链路信息不包括中间网络设备的情况下，则该下游网络设备为目标网络设备。
例如，结合图3至图4所示，在源网络设备300确定待运维的目标OMS链路信息用于指示图4所示的目标OMS403的情况下，即可确定该目标OMS403对应的第一输出端口，具体地，该WSS301将业务单板所产生的光信号传输至与第一输出端口连接的WSS309，光信号的传输方向经由WSS301和WSS309的偏转后，能够经由第一输出端口从源网络设备300输出，进而沿目标OMS403所包括的各个网络设备进行传输，直至传输至目标网络设备411，从而实现光信号沿目标OMS403所包括的各个网络设备进行传输的目的。
以下进一步结合图5所示对第一输出端口进行说明：
本实施例所示的位于不同位置处的WSS用于将光信号传输至不同的OMS内，以使经由不同的WSS偏转了传输方向的光信号，能够以不同的维度方向从源网络设备输出。本实施例以WSS309用于将光信号输入至待运维的目标OMS403内为例进行示例性说明：
本实施例中，与WSS309依次通过光纤连接有光放大器501和光纤线路接口板(fiber interface board，FIU)502。
可选地，本实施例所示的第一输出端口可为该光放大器501的输出端口，即来自WSS309的光信号经由光放大器501的第一输出端口向中间网络设备410传输。可选地，本实施例所示的第一输出端口还可为该FIU502，即来自光放大器501的光信号经由FIU502向中间网络设备410传输，本实施例以第一输出端口为光放大器501的输出端口为例进行示例性说明。
步骤203、源网络设备在第一输出端口上获取光信号的第一输出功率值。
可选地，继续如图5所示，在源网络设备300确定第一输出端口为光放大器501的输出端口的情况下，则源网络设备300可获取光信号经由光放大器501的输出端口输出的第一输出功率值。可选地，在源网络设备300确定第一输出端口为FIU502的输出端口的情况下，则源网络设备300可获取光信号经由FIU502的输出端口输出的第一输出功率值。
步骤204、源网络设备通过第一光纤向中间网络设备发送第一输出功率值。
继续如图4和图5所示，本实施例所示的第一光纤连接在源网络设备300和中间网络设备410之间的光纤，源网络设备300通过该第一光纤将第一输出功率值传输至中间网络设备410。具体地，若第一输出端口为光放大器501的输出端口，则第一光纤包括两段，即光放大器501和FIU502之间的光纤以及连接在FIU502和中间网络设备410之间的光纤。若第一输出端口为FIU502的输出端口，则第一光纤为连接在FIU502和中间网络设备410之间的光纤。
以下对源网络设备具体是如何发送该第一输出功率值的进行说明：
可选地，源网络设备通过第一光纤传输第一光监控信道(optical supervisory channel，OSC)，以向中间网络设备发送该第一输出功率值。其中，第一OSC用于传输对光信号在不同的网络设备之间传输的过程进行监控的数据，即第一OSC的主要功能是监控光信号在网络设备之间传输的情况。
具体地，源网络设备301可向中间网络设备410传输多路具有不同波长的光信号，例如，源网络设备301向中间网络设备410传输五路光信号，分别具有的波长为λ 1、λ 2、λ 3、λ 4以及λ 5。其中，λ 2、λ 3、λ 4以及λ 5可为承载业务的光信号，为监控承载业务的光信号的传输的过程，则可通过具有波长为λ 1的光信号(即第一OSC)对传输情况进行监控。为实现第一OSC的监控功能，则可通过第一OSC传递监控信息，操作维护管理(operation administration and maintenance，OAM)信息等。
本实施例中，将待通过第一OSC传输的信息(监控信息、OAM信息等)封装成数据帧，并将该数据帧调制到第一OSC上，继续以图5所示为例，源网络设备300将待通过第一OSC传输的信息封装成数据帧，并将该数据帧调制到第一OSC上，FIU502将第一OSC和来自光放大器501的光信号进行复用后，通过第一光纤向中间网络设备410进行传输。本实施例对封装的具体方式不做限定，例如，该封装可为以太帧封装。
本实施例中，可通过第一OSC传输第一输出功率值，具体地，所述源网络设备300将第一输出功率值封装至该数据帧的开销区中的第一字节中，该第一字节占用第一OSC的目标带宽。本实施例对第一字节的数量和具体位置不做限定，只要源网络设备300和中间网络设备410均已确定该第一字节用于承载第一输出功率值即可。
可选地，本实施例所示的已调制在第一OSC上的数据帧的开销区中包括所述第一字节和第二字节，所述第一字节和所述第二字节为所述数据帧的开销区中所包括的互不相同的字节，所述第一字节用于承载所述第一输出功率值，而所述第二字节为被DCN通道所占用的字节，可见，所述DCN通道未占用所述目标带宽。其中，所述DCN通道通过占用第二字节以传输用于对网络设备进行管理和/或维护的相关信息，本实施例对DCN所传输的具体信息不做限定。
采用第一OSC的目标带宽传输第一输出功率值的优势在于，中间网络设备在接收到经由第一光纤的各路光信号的情况下，仅需对第一OSC进行解析以获取第一输出功率值，继续结合上述示例，中间网络设备410的FIU501对来自第一光纤的信号进行解复用以获取用于承载业务的光信号(即具有λ 2、λ 3、λ 4以及λ 5的光信号)以及用于承载第一输出功率值等信息的第一OSC(即具有λ 1的光信号)。本实施例所示的第一字节和第二字节互不相同，从而使得第一输出功率值的传输不会占用DCN通道，从而使得源网络设备300在将第一输出功率值向中间网络设备410传输的过程中，无需占用DCN通道的带宽，提高了DCN通道的带宽的利用率，而且避免了第一输出功率值的传输对DCN通道的影响。
步骤205、中间网络设备在输入端口上获取光信号的第一输入功率值。
本实施例对中间网络设备的设备类型不做限定，只要中间网络设备能够将来自源网络设备的光信号向目标网络设备转发即可，本实施例以中间网络设备为光线路放大设备(optical line amplifier，OLA)为例进行示例性说明，中间网络设备的具体结构可参见图5所示，需明确的是，本实施例对中间网络设备的具体结构的说明为可选地示例，不做限定。
如图5所示可知，中间网络设备410包括依次通过光纤连接的FIU510、光放大器511以及FIU512，对FIU和光放大器的具体说明请详见上述所示，不做赘述。由上述图3所示的说明可知，源网络设备包括多个分别与位于不同位置处的WSS(WSS302至WSS309)连接的输出端口，光信号从不同的输出端口输出，即可使得光信号沿不同的方向进行传输，而中间网络设备仅具有一个输入端口和一个输出端口，中间网络设备无需对光信号的传输方向进行改变，中间网络设备仅用于将从输入端口输入的光信号传输至输出端口，以从中间网络设备输出，可见，中间网络设备仅用于实现对光信号的转发。
由上述所示可知，第一光纤的起点可连接在光放大器501的输出端口，也可连接在FIU502的输出端口，该第一光纤的终点可连接在中间网络设备410的FIU510的输入端口上，也可连接在中间网络设备410的光放大器511的输入端口上，本实施例以第一光纤的终点连接在光放大器511的输入端口上为例进行示例性说明，例如，中间网络设备411的FIU601将已接收到的光信号进行解复用以获取用于承载业务的光信号以及第一OSC，对用于承载业务的光信号以及第一OSC的具体说明，请详见步骤204所示，具体不做赘述，FIU601将用于承载业务的光信号向光放大器602传输，中间网络设备411即可在光放大器602的输入端口上获取用于承载业务的光信号的第一输入功率值。
步骤206、中间网络设备获取第一光纤的光纤衰耗。
本实施例所示的中间网络设备根据第一输出功率值以及在中间网络设备的输入端口上 获取到的第一输入功率值，即可获取第一光纤的光纤衰耗，具体地，中间网络设备可根据如下所示的公式1获取第一光纤的光纤衰耗：
公式1：第一光纤的光纤衰耗＝Pout-Pin-目标衰减。
其中，Pout为上述所示的第一输出功率值，Pin为在中间网络设备的输入端口上获取到的第一输入功率值，如图5所示，若第一光纤的起点为光放大器501的输出端口，终点为光放大器511的输入端口，则该目标衰减包括FIU502的固有衰减、FIU510的固有衰减、连接在光放大器511和FIU510之间的可调光衰减器(variable optical attenuator，VOA)的衰减值的和。
本实施例中，由中间网络设备获取第一光纤的光纤衰耗为例进行示例性说明，在其他示例中，也可由中间网络设备将源网络设备的第一输出功率值以及在中间网络设备的输入端口上获取到的第一输入功率值，向目标网络设备发送，进而由目标网络设备根据上述所示的公式1计算出第一光纤的光纤衰耗，可见，在此种示例下，目标OMS的目标网络设备能够获取目标输入功率值和目标输出功率值，进而基于公式1所示计算出目标光纤的光纤衰减。其中，所述目标输入功率值为光信号输入至目标光纤的功率值，所述目标输出功率值为光信号从所述目标光纤输出的功率值，所述目标光纤为连接在所述源网络设备和所述中间网络设备之间的第一光纤，和/或，所述目标光纤为连接在所述目标OMS所包括的任意相邻的两个所述中间网络设备之间的光纤。
步骤207、中间网络设备在输出端口上获取第二输出功率值。
本实施例中，中间网络设备在输出端口上获取第二输出功率值的具体说明，可参见步骤203所示的源网络设备在第一输出端口上获取光信号的第一输出功率值的具体说明，不做赘述。
步骤208、中间网络设备将第一光纤的光纤衰耗以及第二输出功率值向目标网络设备发送。
本实施例中，中间网络设备发送第一光纤的光纤衰耗以及中间网络设备的输出端口上获取的第二输出功率值的过程，可参见上述步骤204所示的源网络设备向中间网络设备发送第一输出功率值的具体过程，不做赘述。
本实施例中，中间网络设备和目标网络设备之间通过第二光纤连接，可选地，若第二光纤传输一个第二OSC的情况下，则中间网络设备可将第二输出功率值和第一光纤的光纤衰耗通过已调制在该第二OSC上的第三字节向目标网络设备发送，即第二OSC的第三字节已承载第二输出功率值和第一光纤的光纤衰耗，该第三字节占用第二OSC的目的带宽，对第三字节的说明，请参见上述步骤204所示的第一字节的说明，本实施例以第一字节在已调制在第一OSC上的数据帧的开销区的位置和第三字节在已调制在第二OSC上的数据帧的开销区的位置相同为例进行示例性说明，在其他示例中，第一字节在已调制在第一OSC上的数据帧的开销区的位置和第三字节在已调制在第二OSC上的数据帧的开销区的位置也可不同。
本实施例中，已调制在第二OSC上的数据帧的开销区中包括所述第三字节和第四字节，所述第三字节和所述第四字节为所述数据帧的开销区中所包括的互不相同的字节，该第四 字节为DCN通道所占用的字节，对第四字节的具体说明，请详见上述所示的对第二字节的说明，可见，本实施例所示的目标带宽未被DCN通道所占用。
还可选地，在第二光纤用于传输两个或两个以上的第二OCS的情况下，其中，第二光纤所传输的多个第二OSC分别具有不同的波长，中间网络设备可将第二输出功率值和第一光纤的光纤衰耗通过不同的第二OSC的第三字节向目标网络设备发送，例如，第二光纤用于传输具有λ 1的第二OSC和具有λ 2的第二OSC，其中，具有λ 1的第二OSC的第三字节用于承载第一光纤的光纤衰耗，具有λ 2的第二OSC的第三字节用于承载第二输出功率值。
本实施例中，以中间网络设备的下游网络设备为目标网络设备为例进行示例性说明，在其他示例中，中间网络设备的下游网络设备还可为另一中间网络设备，本实施例对源网络设备和目标网络设备之间所连接的中间网络设备的数量不做限定，对其他中间网络设备执行本实施例所示的方法的过程，请详见步骤205至步骤208所示，具体不做赘述。
本实施例中，源网络设备300和中间网络设备410位于第一DCN内，而目标网络设备位于第二DCN内，可见，源网络设备300所位于的DCN和目标网络设备411所位于的DCN互不相同。在中间网络设备410和目标网络设备411位于不同的DCN内的情况下，采用本实施例所示的方法，中间网络设备410能够通过第二光纤所传输的第二OSC的第三字节，向目标网络设备411发送用于对目标OMS进行检测的相关信息(例如第二输出功率值以及第一光纤的光纤衰耗等信息)，采用第二OSC的第三字节进行跨DCN的传输优势在于，中间网络设备410通过第二OSC的目的带宽发送用于对目标OMS进行检测的相关信息，无需占用DCN通道的带宽，降低了第二OSC的目标带宽对第二OSC的DCN通道的影响。
本实施例所示的中间网络设备在获取到第一光纤的光纤衰耗以及第二输出功率值的情况下，无需进行存储和分析，即可直接向目标网络设备发送，节省了中间网络设备的资源，降低了对中间网络设备的负载。
步骤209、目标网络设备接收来自中间网络设备的第二输出功率值以及第一光纤的光纤衰耗。
为更好的理解，以下结合图6所示进行说明，其中，图6为本实施例所示的目标网络设备和所连接的中间网络设备的结构示例图。

本实施例中，在所述源网络设备判断出两个第一输出功率值之间的差的绝对值大于或等于所述第一预设值的情况下，则说明第一光纤劣化的风险较大，则源网络设备立即将第一输出功率值向中间网络设备发送。
可选地，源网络设备可将N个第一输出功率值中的任意一个第一输出功率值向中间网络设备发送，还可选地，源网络设备可将N个第一输出功率值中，在所述第一预设时间段内最后时刻所获取到的第一输出功率值向中间网络设备发送等，具体在本实施例中不做限定。
步骤706、源网络设备每隔第二预设时间段向中间网络设备发送第一输出功率值。
在所述源网络设备判断出两个第一输出功率值之间的差的绝对值小于所述第一预设值的情况下，则说明第一光纤劣化的风险较小，则源网络设备无需立即将第一输出功率值向中间网络设备发送，而且可周期性的向中间网络设备发送第一输出功率值，该周期的持续时间为第二预设时间段，从而使得源网络设备每隔该第二预设时间段向中间网络设备发送所述第一输出功率值。
本实施例对第二预设时间段的持续时间不做限定，只要该第二预设时间段大于所述第一预设时间段即可，例如，在第一预设时间段为2秒的示例下，本实施例以该第二预设时间段为5秒为例进行示例性说明，可见，本实施例所示的源网络设备可每隔5秒向中间网络设备发送一次所述输出功率值，以触发中间网络设备对第一光纤的光纤衰耗的检测。
步骤707、中间网络设备在输入端口上获取光信号的第一输入功率值。

步骤710、中间网络设备判断两个第二输出功率值之间差的绝对值是否大于或等于第一预设值，若是，则执行步骤711，若否，则执行步骤712。
本实施例所示的步骤710的具体执行过程，请参见步骤704所示，具体不做赘述。
步骤711、中间网络设备通过第二光纤向目标网络设备发送第一光纤的光纤衰耗以及第二输出功率值。
步骤712、中间网络设备每隔第二预设时间段向目标网络设备发送第一光纤的光纤衰耗以及第二输出功率值。
本实施例所示的中间网络设备向目标网络设备发送第一光纤的光纤衰耗的具体说明，请详见图2所示的208所示，具体不做赘述。
本实施例所示的中间网络设备向目标网络设备发送第二输出功率值的具体过程，请参见上述步骤705至步骤706所示的源网络设备向中间网络设备发送第一输出功率值的过程，具体不做赘述。
步骤713、目标网络设备接收来自中间网络设备的第二输出功率值以及第一光纤的光纤衰耗。
步骤714、目标网络设备在输入端口上获取光信号的第二输入功率值。
步骤715、目标网络设备获取第二光纤的光纤衰耗。
本实施例所示的步骤713至步骤715的具体执行过程的说明，请详见图2所示的步骤209至步骤211所示，具体不做赘述。
采用本实施例所示的方法，以源网络设备为例，源网络设备向下游网络设备发送第一输出功率值之前，基于第一预设时间段内的两个第一输出功率值之间的差的绝对值与第一预设值的大小关系，即可确定第一光纤的劣化风险的高低，若第一光纤的劣化风险比较高(即第一预设时间段内的两个第一输出功率值之间的差的绝对值大于或等于第一预设值)，则源网络设备即可立即向中间网络设备发送第一输出功率值，以使中间网络设备对第一光纤的光纤衰耗进行检测，以确定第一光纤是否劣化，提高对第一光纤是否劣化的告警的及时性。若第一光纤的劣化风向比较低(即第一预设时间段内的两个第一输出功率值之间的差的绝对值小于第一预设值)，则源网络设备可周期性的向中间网络设备发送第一输出功率值，以降低源网络设备向中间网络设备发送输出功率值的数据量，降低中间网络设备需要处理的数据量。
