相关申请的交叉引用

技术领域
本公开涉及网络通信技术领域，特别涉及一种光通道保护方法、装置和系统。
背景技术
传统波分设备组网时，电层板卡和光层保护板卡通常在同一台设备上，当电层板卡承载的业务出现光传输网络(Optical Transport Network，OTN)告警、性能劣化告警时，电层板卡可以产生自动保护倒换(Automatic Protection Switching，APS)信令，该信令可以直接通过背板总线传递到光层保护板卡，使光层保护板卡发生光路倒换。
在光层设备和电层设备异厂商组网的情况下，电层板卡和光层保护板卡不在同一台设备上，光层保护板卡无法接收电层板卡的APS信令，因此，当电层板卡出现OTN告警和性能劣化告警时，如果未达到光层保护板卡的功率倒换门限，则电层板卡将持续出现误码，影响业务正常运行。

图1是示出根据本公开一些实施例的光通道保护方法的流程图。在本公开实施例中，电层模块与光层保护模块位于不同设备上。如图1所示，本公开实施例的光通道保护方法包括：
步骤S110：接收电层模块的告警信息。
在一些实施例中，光通道保护方法可以由电层模块和光层保护模块之外的控制器执行。该控制器可以由不同的厂家提供，例如，由和提供电层模块或光层保护模块的厂商不同的第三方厂家提供。
在一些实施例中，控制器通过带外数据通信网络(Data Communication Network，DCN)接收电层模块的告警信息。带外数据通信网络，一般是指业务通道之外的其他网络通道，用于传输网络管理信息。
在一些实施例中，电层模块的告警信息包括OTN层告警信息，比如输入光丢失告警、帧丢失告警、光通道传送单元层告警指示信号(Optical Channel Transport Unit-Alarm Indication Signal，OTUK-AIS)、光通道数据单元层-通道监视-告警指示信号(Optical Channel Data Unit-Path Monitoring-Alarm Indication Signal，ODUK-PM-AIS)、光通道数据单元层-通道监视-性能劣化告警(Optical Channel Data Unit-Path Monitoring-Degraded，ODUK-PM-DEG)。
步骤S120：确定电层模块的标识。

在一些实施例中，电层模块的标识包括电层模块所在电层板卡的标识、槽位和端口信息。
步骤S130：根据电层模块的标识、以及预先配置的电层模块与光层保护模块的对应关系，确定电层模块对应的光层保护模块。
其中，电层模块与光层保护模块位于不同的设备上。例如，电层模块位于厂商A提供的电层设备上，光层保护模块位于厂商B提供的光层设备上，电层模块与光层保护模块这两者在物理上是隔离的。
在一些实施例中，控制器根据发送告警信息的电层模块的标识，查找预 先配置的电层模块与光层保护模块的对应关系，以确定与发送告警信息的电层模块对应的光层保护模块。

在一些实施例中，光通道保护方法还包括：配置电层模块与光层保护模块的对应关系，并将该对应关系进行存储。例如，通过人机交互界面配置电层模块与光层保护模块的对应关系，并将该对应关系存储于数据库中。
步骤S140：向电层模块对应的光层保护模块发送光通道切换命令。
在一些实施例中，根据电层模块对应的光层保护模块的当前工作状态，生成光通道切换命令；将光通道切换命令发送至电层模块对应的光层保护模块。
在一些实施例中，工作状态包括正常状态和倒换状态，其中，正常状态表明光层保护模块工作在主光通道，即业务数据通过主光通道进行传输，倒换状态表明光层保护模块工作在备用光通道，即业务数据通过备用光通道进行传输。在这些实施例中，根据电层模块对应的光层保护模块的当前工作状态，生成光通道切换命令包括：在电层模块对应的光层保护模块的当前工作状态表明光层保护模块当前工作在主光通道的情况下，生成第一光通道切换命令，其中，第一光通道切换命令用于指示由主光通道倒换至备用光通道；在电层模块对应的光层保护模块的当前工作状态表明光层保护模块当前工作在备用光通道的情况下，生成第二光通道切换命令，其中，第二光通道切换命令用于指示由备用光通道倒换至主光通道。
在一些实施例中，第一光通道切换命令和第二光通道切换命令的类型为故障倒换类型，即表明该倒换是由故障引发的。在另一些实施例中，第一光通道切换命令和第二光通道切换命令也可为人工倒换、强制倒换类型。
在本公开实施例中，针对电层和光层模块异厂商系统，实现了基于电层模块的告警信息触发光层保护模块进行光通道倒换，从而能够在未达到光层保护板卡的功率倒换门限的情况下，也能进行光通道切换，有效缓解了电层模块持续出现误码的情况，降低了对业务正常运行的影响，提高了系统的鲁棒性。

在一些实施例中，第三方控制器通过带外DCN向电层模块对应的光层保护模块发送光通道切换命令。
