具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
在一些实施例中，虽然在系统示意图中进行了功能模块划分，在流程图中示 出了逻辑顺序，但是在某些情况下，可以以不同于系统中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书和权利要求书及上述附图中的术语第一、第二等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
随着社会的发展，急剧增长的数据流量对光传送网络的带宽容量提出了越来越高的要求，DWDM(Dense Wavelength Division Multiplexing，密集波分复用)和OTN(Optical Transport Network，光传送网络)传输领域中速率超过100G的技术统一称作超100G传输技术，正成为高速传输技术的主要发展方向，其中，在ITU-T(International Telecommunication Union，国际电信联盟)G.709中定义了光传送接口标准，其中定义光层信号中的非超100G信号和超100G信号分别由OCH(Optical Channel，光信道)和OTSi(Optical Tributary Signal，光支路信号)层信号承载，同时，电层中非超100G信号和超100G信号分别由OTUk(Optical Transport Unit-k，光传送单元k)/ODUk(Optical Channel Data Unit-k，光通道数据单元k)和OTUCn(Optical Transport Unit-Cn，光传送单元Cn)/ODUCn(Optical Channel Data Unit-Cn，光通路数据单元Cn)层信息承载。
在长距离传输过程中，当光层无法直接传递信号到宿端时，需要在途中通过电中继方式进行光-电-光转换，而现有电中继方式采用转发器进行，只能通过固定转发的方式进行光-电-光转换，缺乏电层交换能力，无法在对超100G电层信号进行交叉调度的同时实现超100G电中继功能。
为至少解决上述问题，本申请公开了一种超100G电中继的控制方法、控制器以及存储介质，其中，超100G电中继的控制方法包括，接收超100G的第一光层信号，对第一光层信号进行解映射处理，得到超100G的光通路数据单元信号，根据预设调度方法对光通路数据单元信号进行交叉调度处理，以将光通路数据单元信号传输至目标输出端口，对光通路数据单元信号进行映射处理，得到超100G的第二光层信号，并通过目标输出端口输出第二光层信号，其中，通过对超100G的光通路数据单元信号进行交叉调度，即在ODUCn层面进行电信号交换连接，使分离型板卡上能够支持超100G电中继方式，实现超100G电中继功能，使超100G业务组网更加灵活。
下面结合附图，对本申请实施例作进一步描述。
参考图1，图1为本申请一实施例提出的光-电-光中继转发示意图，由于光层信号传输存在的损耗等因素，长距离传输当光层无法直接传递信号到宿端时，需要在途中将光信号转换为电信号重新再生为光信号发送出去(光-电-光转换)，这种方式称之为电中继方式。
在一些实施例中，如图1(a)所示，在电中继的光-电-光转换时，一般会经过三个过程，光-电转换包括的功能是光信号终结、电信号解映射适配，电-光转换包括的功能是电信号映射适配和光信号再生，其中，电信号连接则可分为固定连接和交换连接两种。
在一些实施例中，如图1(b)所示，图1(b)对应电信号固定连接方式，在电信号固定连接方式中，一般采用合一型单板设计，其中中间负责电学号固定连接的结构本称为转发器或中继板，在电信号固定连接方式传输信号的过程中，信号只能从一端接入从另一端固定输出，存在组网不够灵活，必须在业务路径上提前部署中继板卡的问题；如图1(c)所示，图1(c)对应电信号交换连接方式，电信号交换连接采用分离的板卡设计，对应可实现多业务、多颗粒、多维度的任意交叉调度，无需提前部署中继板，业务生成时根据需要设置电信号交换连接，通过线路板和交叉板配合在需要的端口间临时生成光-电-光中继，其中，目前的OTN产品电信号交换连接都是直接根据设置明确的调度方式进行调度，比如设置采用ODU4，则只会采用ODU4方式交叉，其它信号接入，直接在业务光-电转换解映射时即返回失败，并不具备获取接入业务的业务速率和带宽等参数能力。
参考图2，在一些情形中，超100G电层ODUCn交换连接调度方式并没有在ITU标准中定义，而只在ITU-T G.709附录中说明了采用转发器的电中继方式，其中，光传送网络包括源站点1、电中继节点2和宿站点3，电中继节点2为单个转发器，光-电-光转换在单个转发器中进行，只能是固定转发的方式，缺乏电层交换能力，当希望在首尾端口建立超100G管道时，在一些情形中只能采用超100G转发器中继板方式，导致工程应用时中继板卡的部署需要提前规划，管道和业务组网功能受限。
参考图3，图3为本申请另一实施例提出的超100G电中继的控制方法的流程图，在一些实施例中，超100G电中继的控制方法，包括但不限于以下步骤：
步骤S310，接收超100G的第一光层信号；
步骤S320，对第一光层信号进行解映射处理，得到超100G的光通路数据单元信号；
步骤S330，根据预设调度方法对光通路数据单元信号进行交叉调度处理，以将光通路数据单元信号传输至目标输出端口；
步骤S340，对光通路数据单元信号进行映射处理，得到超100G的第二光层信号，并通过目标输出端口输出第二光层信号。
在一些实施例中，超100G电中继的控制方法应用于支路板、线路板分离架构的OTN机架环境中，分离架构下支路/线路板和集中交叉单板配合使用，可通过集中交叉单板进行各级别ODUk颗粒业务调度，实现更加灵活的电层信号调度及更高的带宽利用率。
在一些实施例中，超100G的第一光层信号即为超100G的OTSi信号，对第一光层信号进行解映射处理，得到超100G的光通路数据单元信号，其中超100G的光通路数据单元信号即为ODUCn，其中，对于100G之上的带宽，传统的ODUk(k＝2、3、4)是无法提供足够的频谱宽度，来直接承载超100G业务，因此，国际ITU制定了ODUCn映射来处理相应的超100G业务。
在一些实施例中，根据预设调度方法对光通路数据单元信号进行交叉调度处 理，以将光通路数据单元信号传输至目标输出端口，对光通路数据单元信号进行映射处理，得到超100G的第二光层信号，并通过目标输出端口输出第二光层信号，其中，在ODUCn层进行电信号交换调度时，只交换ODUCn电信号，而不交换ODUk信号，在配置为ODUCn调度方式后，在光-电转换的过程中，对一端输入的超100G的光层信号只解映射到ODUCn层，而不继续解映射到ODUk层，在该模式下，端口上只能解析超100G光层信号，其它非超100G OCH信号会解映射失败；同时，配置ODUCn调度方式后，在电-光转换的过程中，在另一端对ODUCn映射封装到超100G光信号发送出去，进而实现在ODUCn层面进行电信号交换连接，使分离型板卡上能够支持超100G电中继方式，实现超100G电中继功能，使超100G业务组网更加灵活。
在一些实施例中，参考图4，在一些情形中，在进行超100G传输过程中，如果采用分离型板卡样式进行交叉调度，在光-电转换时会进行两级解映射即对超100G光层信号终结后连续解映射先到ODUCn再到ODUk，电-光转换同理也是两级映射，从ODUk到ODUCn再到光信号的再生，其中，由于光-电转换时的两级映射，导致在ODUk层面进行电信号交换连接时，无法实现超100G电中继功能，只能在首站点和中间站点形成一个超100G管道，在中间站点和宿站点3再形成另外一个超100G管道，而不能形成一个完整的超100G管道，存在ODUCn层OAM(Operation Administration and Maintenance，操作管理和维护)开销会在光-电转换时终结，只有ODUk层的开销会被透传，告警传递和时延测量等依赖开销的功能都在超100G层面受到限制的问题，故在本申请提出的超100G电中继的控制方法，在光-电转换时会进行一级解映射即对超100G光层信号终结后进行解映射到ODUCn，电-光转换同理也是一级映射，从ODUCn到光信号的再生，实现在ODUCn层面提供电信号交换调度能力，能使分离型板卡上能够支持超100G电中继方式，提供ODUCn层面的电中继功能，使首尾站点间形成一个超100G管道，使业务组网更加灵活。
在一些实施例中，电中继节点包括输入端口和目标输出端口，超100G电中继的控制方法，包括，通过输入端口接收超100G的第一光层信号，并对第一光层信号进行解映射处理，得到超100G的光通路数据单元信号，根据预设调度方法对光通路数据单元信号进行交叉调度处理，以将光通路数据单元信号传输至目标输出端口，通过目标输出端口对光通路数据单元信号进行映射处理，得到超100G的第二光层信号，并通过目标输出端口输出第二光层信号，其中，通过电中继节点中交叉板上的交叉调度配置，形成输入端口与目标输出端口之间的通道，进而实现在ODUCn层面上的交换调度处理。
在一些实施例中，参考图5，图5为超100G电中继的控制方法的原子模型图，其中，在电中继节点2线路侧到背板侧的过程中，将DWDM波长信号通过光/电转换并逐层解映射到ODUCn层信号通过电中继节点2中的交叉板4进行调度，即先进行OTSI终结再进行OTUCn/ODUCn适配，将光层信号解映射为ODUCn层信 号，反之，背板侧到线路侧的过程中，将背板调度过来的ODUCn层信号进行复用和映射，完成电/光转换后，转换为符合DWDM系统要求的标准波长信号发送出去，即先进行OTUCn/ODUCn适配再进行OTSI终结，在电中继节点2线路对信号进行调度时，仅将解映射到ODUCn信号，通过背板发送到电中继节点2中的交叉板4，由交叉板4实现ODUk粒度的交叉调度，最终形成ODUCn连接，进而通过在ODUCn层面进行电信号交换连接，使分离型板卡上能够支持超100G电中继方式，实现超100G电中继功能，使超100G业务组网更加灵活。
参考图6，图6为本申请另一实施例提出的超100G电中继的控制方法的流程图，在一些实施例中，超100G电中继的控制方法，包括但不限于以下步骤：
步骤S610，根据预设调度方法确定目标输出端口；
步骤S620，根据目标输出端口对光通路数据单元信号进行交叉调度配置，以使光通路数据单元信号传输至目标输出端口。
在一些实施例中，根据预设调度方法确定目标输出端口，根据目标输出端口对光通路数据单元信号进行交叉调度处理，以使光通路数据单元信号传输至目标输出端口，其中，通过在电中继节点2的输入端口和目标输出端口进行交叉调度处理，使超100G信号在这两个端口间传递，在ODUCn层面进行电信号交换连接，使分离型板卡上能够支持超100G电中继方式，实现超100G电中继功能，使超100G业务组网更加灵活。
参考图7，图7为本申请另一实施例提出的超100G电中继的控制方法的流程图，在一些实施例中，超100G电中继的控制方法，包括但不限于以下步骤：
步骤S710，根据光通路数据单元信号得到数据净荷；
步骤S720，根据目标输出端口对数据净荷进行交叉调度处理，以将数据净荷传输至目标输出端口。
在一些实施例中，根据光通路数据单元信号得到数据净荷，根据目标输出端口对数据净荷进行交叉调度处理，以将数据净荷传输至目标输出端口，使数据净荷能在ODUCn层进行传输，克服了在一些情形中只能在首站点和中间站点形成一个超100G管道，在中间站点和宿站点3再形成另外一个超100G管道，而不能形成一个完整的超100G管道，此时ODUCn层OAM开销会在光-电转换时终结，只有ODUk层的开销会被透传，告警传递和时延测量等依赖开销的功能都在超100G层面受到限制的问题，使超100G电中继的控制方法能在ODUCn层传输数据净荷，进而传输数据开销，在超100G层面实现告警传递和时延测量等依赖开销的功能。
参考图8，图8为本申请另一实施例提出的超100G电中继的控制方法的流程图，在一些实施例中，超100G电中继的控制方法，包括但不限于以下步骤：
步骤S810，根据光通路数据单元信号得到帧开销数据；
步骤S820，根据目标输出端口对帧开销数据进行交叉调度处理，以将帧开销数据传输至目标输出端口。
在一些实施例中，根据光通路数据单元信号得到帧开销数据，根据目标输出 端口对帧开销数据进行交叉调度处理，以将帧开销数据传输至目标输出端口，其中，通过本实施例中超100G的电中继控制方法，能使ODUCn的信号在两个端口间交换，并且ODUCn的信号至少包括ODUCn的数据净荷，进而通过透明传输ODUCn的OAM开销数据，或对于ODUCn的OAM开销可单独配置透传，保证开销可以被透传到源或宿站点3，进而在超100G层面实现告警传递和时延测量等依赖开销的功能。
参考图9，图9为本申请另一实施例提出的超100G电中继的控制方法的流程图，应用于分离型光传送网络，分离型光传送网络包括源站点1、电中继节点2和宿站点3，电中继节点2包括输入端口和目标输出端口，在一些实施例中，超100G电中继的控制方法，包括但不限于以下步骤：
步骤S910，源站点将接收到的客户侧业务信号进行映射处理，得到超100G的第一光层信号，并将第一光层信号发送至电中继节点；
步骤S920，电中继节点通过输入端口接收第一光层信号，对第一光层信号进行解映射处理，得到光通路数据单元信号，并根据预设调度方法对光通路数据单元信号进行交叉调度处理，将光通路数据单元信号传输至目标输出端口；
步骤S930，电中继节点通过目标输出端口对光通路数据单元信号进行映射处理，得到超100G的第二光层信号，并通过目标输出端口将第二光层信号发送至宿站点。
在一些实施例中，电中继节点根据预设调度方法对光通路数据单元信号进行交叉调度处理，以将光通路数据单元信号传输至目标输出端口，对光通路数据单元信号进行映射处理，得到超100G的第二光层信号，并通过目标输出端口输出第二光层信号，其中，由于电中继节点在ODUCn层进行电信号交换调度时，只交换ODUCn电信号，而不交换ODUk信号，在配置为ODUCn调度方式后，在光-电转换的过程中，对一端输入的超100G的光层信号只解映射到ODUCn层，而不继续解映射到ODUk层，在电-光转换的过程中，在另一端对ODUCn映射封装到超100G光信号发送出去，进而实现在ODUCn层面进行电信号交换连接，使分离型板卡上能够支持超100G电中继方式，实现超100G电中继功能，使超100G业务组网更加灵活。
在一些实施例中，源站点将接收到的客户侧业务信号进行映射处理，得到超100G的第一光层信号，并将第一光层信号发送至电中继节点，电中继节点进行交叉调度，并将第二光层信号发送至宿站点，进而生成源站点与宿站点之间的超100G管道，使该超100G业务或管道上的相关OAM开销可以透明传输，进而实现相关告警、时延测量等依赖开销的功能，并且使超100G业务组网更加灵活。
参考图10，图10为本申请一实施提出的超100G电中继应用于分离型光传送网络的示意图，其中，分离型光传送网络包括具备超100G信号中继能力的分离型OTN设备，分离型OTN设备中包括支路板、线路板和交叉板4。
在一些实施例中，支路板用于客户侧信号和背板信号的转换，在客户侧到背 板侧，客户侧业务信号转换后经封装映射处理、OTN成帧和FEC编码处理等操作，输出ODU层信号经背板送至交叉板4进行调度；反之，背板侧到客户侧，将背板调度过来的ODU层信号进行映射和复用最终通过转换为客户业务信号发出，支路板只会配置于业务的源站点1和宿站点3，在本申请中不涉及支路板的变更，支路板的具体的设置细节不对本申请方案构成限制。
在一些实施例中，线路板用于线路侧信号和背板信号的转换。线路侧到背板侧，将DWDM波长信号通过光/电转换并逐层解映射到ODU层信号通过背板发送到交叉板4进行调度；反之，背板侧到线路侧，将背板调度过来的ODU层信号进行复用和映射，完成电/光转换后，转换为符合DWDM系统要求的标准波长信号发送出去。本申请方案中涉及在中间站点，即电中继节点2中用于进行中继的线路板，在信号转换过程中，只将光层信号解映射到ODUCn信号，并通过背板发送到交叉板4，进行后续交叉调度处理。
在一些实施例中，交叉板4用于对支路板/线路板端口调度过来的ODU层信号根据配置调度到其它支路板/线路板端口。本专利涉及中间站点用于进行中继的线路板，通过对信号进行交叉调度处理使业务组网更加灵活。
在一些实施例中提供了一种超100G管道的电中继控制方法，其中，通过源站点1将接收到的客户侧业务信号进行映射处理，得到超100G的第一光层信号，并将第一光层信号发送至电中继节点2，电中继节点2通过输入端口接收第一光层信号，对第一光层信号进行解映射处理，得到光通路数据单元信号，并根据预设调度方法对光通路数据单元信号进行交叉调度处理，将光通路数据单元信号传输至目标输出端口，电中继节点2通过目标输出端口对光通路数据单元信号进行映射处理，得到超100G的第二光层信号，并通过目标输出端口将第二光层信号发送至宿站点3，将电中继光电光转换过程中ODUCn信号进行交叉透传，形成一条完整的超100G管道，提升管道控制简便性。
在一些实施例中，根据预设调度方法对光通路数据单元信号进行交叉调度处理，将光通路数据单元信号传输至目标输出端口，包括，电中继节点2根据预设调度方法确定目标输出端口，电中继节点2根据目标输出端口对光通路数据单元信号进行交叉调度处理，以使光通路数据单元信号传输至目标输出端口。
在一些实施例中，根据预设调度方法对光通路数据单元信号进行交叉调度处理，将光通路数据单元信号传输至目标输出端口，包括，电中继节点2根据光通路数据单元信号得到数据净荷，电中继节点2根据目标输出端口对数据净荷进行交叉调度处理，以将数据净荷传输至目标输出端口。
在一些实施例中，根据目标输出端口对光通路数据单元信号进行交叉调度处理，以将光通路数据单元信号传输至目标输出端口，包括，根据光通路数据单元信号得到帧开销数据，根据目标输出端口对帧开销数据进行交叉调度处理，以将帧开销数据传输至目标输出端口。
在一些实施例中，参考图10，源站点将接收到的客户侧业务信号进行映射 处理，得到超100G的第一光层信号，并将第一光层信号发送至电中继节点，电中继节点进行交叉调度，并将第二光层信号发送至宿站点，进而生成源站点与宿站点之间的超100G管道(ODUCn通道)，其中，由于电中继节点中只交换ODUCn电信号，而不交换ODUk信号，在ODUCn层面进行电信号交换连接，源站点生成的帧开销数据在ODUCn层面上的传输不会在电中继节点中断，使源站点可以通过超100G管道透明传输帧开销数据，即源站点生成帧开销数据，并通过上述电中继节点将帧开销数据透明传输至宿站点，进而在超100G层面实现告警传递和时延测量等基于帧开销数据所进行的功能。
在一些实施例中，超100G管道的电中继控制方法还包括，在源站点1与电中继节点2之间建立用于传输光支路信号和OTUCn的第一通道，在电中继节点2与宿站点3之间建立用于传输光支路信号和CN光传送单元的第二通道，通过第一通道、第二通道和电中继节点2，在源站点1与宿站点3之间传输光支路信号和OTUCn信号。
在一些实施例中，超100G管道的电中继控制方法还包括，在控制宿站点根据第二光层信号建立源站点1与宿站点之间的超100G管道之后，根据超100G管道生成用于传输低于100G的ODUk层信号的数据链路。
