一种业务保护方法、装置和系统
相关申请的交叉引用
本申请基于申请号为201910613233.1、申请日为2019年07月09日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此以引入方式并入本申请。
技术领域
本申请实施例涉及但不限于通信领域，尤指一种业务保护方法、装置和系统。
背景技术
随着以太网的飞速发展，同步数字体系(SDH，Synchronous Digital Hierarchy)、光传送网(OTN，Optical Transport Network)、分组传送网(PTN，Packet Transport Network)业务等多业务大承载的需求也越来越紧迫，GB/s到TB/s级速率的业务传输大量分布于通信接入、城域和主干传输系统中。一旦出现主干线毁坏等故障将中断大量的业务，必须设计可靠的主干线业务保护系统，提高OTN传输网络的生存能力，完善和提高保护倒换技术。
如图1所示，保护系统一般都是由自动功率状态(APS，Automatic Power State)控制器(APSC，APS Controller)、检测器(Monitor)、执行器(Selector)、协议传递器。其中，检测器负责告警的检测；APS控制器负责保护协议的计算以及整个保护系统流程的控制；执行器负责业务的倒换；协议传递器负责APS协议的传递。
如图2所示，传统的光通道保护借助于光保护(OP，Optical Protection)板来实现保护，控制器、检测器、执行器都在OP板上，当各类客户业务在第 一设备的客户业务接入线卡汇聚后，在第一设备的混合业务传输线卡上传输，并通过光纤传输到第二设备的混合业务传输线卡，再从第二设备的客户业务接入线卡输出。该类保护通过在光纤上设置OP板(即图2中的SOP)来检测光功率的变化，当光功率低于一定门限时触发倒换，从而实现倒换保护。但是，该种方法需要额外的光保护类单元(即OP板)来进行保护，并且对故障检测效率较低，即仅能检测光层的告警触发倒换，而无法检测业务层面的告警信号，在业务层面产生告警信号时无法及时触发倒换，从而导致业务传输失败。

具体实施方式
下文中将结合附图对本申请实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
参见图3，在本申请实施例中，在第一设备设置第二混合业务传输线卡，在第二设备设置第四混合业务传输线卡，作为第一混合业务传输线卡和第三混合业务传输线卡的保护路径。也就是说，第一混合业务传输线卡和第二混合业务传输线卡具有保护关系，第三混合业务传输线卡和第四混合业务传输线卡具有保护关系。
图3中，第一混合业务传输线卡和第三混合业务传输线卡之间通过高阶OTU端口进行业务传输，第二混合业务传输线卡和第四混合业务传输线卡之间通过高阶OTU端口进行业务传输，第三混合业务传输线卡和第二集中式控制单元之间通过低阶OTU端口进行业务传输，第四混合业务传输线卡和第二集中式控制单元之间通过低阶OTU端口进行业务传输。
在创建保护路径时，当配置高阶OTU端口保护时，复制一条低阶OTU端口保护配置与工作路径相同的保护路径，这样，使得保护路径上的低阶OTU端口也能够进行保护倒换，从而保证保护路径上的通过低阶OTU端口传输的业务(如PTN业务，SDH业务等)能够得到保护倒换，如图4(a)所示，低阶OTU端口没有保护配置，则复制一条没有配置低阶OTU端口保护的保护路径，如图4(b)、图4(c)、图4(d)所示，低阶OTU端口具有保护配置时，则复制一条配置具有相同低阶OTU端口保护的保护路径。例如，对于宿为高阶A1的交叉，再复制一条源不变，到宿为A2的交叉。
在进行保护倒换时，先进行高阶OTU端口保护倒换，再进行低阶OTU端口保护倒换。例如，在高阶OTU端口保护倒换后，对于源为高阶A1的交叉，做切换动作，即宿不变，源切换为高阶A2的交叉，如图4(a)所示。高阶保护完成后，低阶有2A1Z/2A2Z，再根据低阶保护倒换，针对低阶就可以刷新了保护组A1/A2定位信息。外部呈现的还是原来工作路径配置，对于 保护通道交叉只是内部处理，对外不呈现。
用户在配置工作路径的低阶通道承载的业务后，检测到配置了高阶OTU端口保护时，通过集中式控制单元将工作路径的业务配置信息复制到保护路径中进行配置。其中，工作路径是指第一混合业务传输线卡和第三混合业务传输线卡组成的路径，保护路径是指第二混合业务传输线卡和第四混合业务传输线卡组成的路径。
那么，第一集中式控制单元将第一混合业务传输线卡的第一业务配置信息复制到第二混合业务传输线卡中进行业务配置，第二集中式控制单元将第三混合业务传输线卡的第二业务配置信息复制到第四混合业务传输线卡中进行业务配置。
在第一设备中，
第一客户业务接入线卡接收到业务数据，将业务数据发送给第一集中式控制单元；
第一集中式控制单元进行交叉调度后，根据保护配置信息将业务数据复制成两份，分别发送给第一混合业务传输线卡和第二混合业务传输线卡；
其中，交叉调度是指使用OTN的第一客户业务接入线卡，第一混合业务传输线卡，第二混合业务传输线卡，第一集中式控制单元后，第一客户业务接入线卡负责将多种客户信号变成若干ODU0、ODU1、ODU2信号，通过第一集中式控制单元，可将若干ODUk信号(可来自不用支路板位)合入一个线路板的OTU2(10G)。这样对OTU2(波分侧)的利用就很灵活。客户业务需要改用另一个波长传也很容易，只要远程修改交叉，不必上站连纤。
其中，保护配置信息包括具有保护关系的工作混合业务传输线卡，例如第一混合业务传输线卡和第二混合业务传输线卡之间具有保护关系，第三混合业务传输线卡和第四混合业务传输线卡之间具有保护关系。
第一混合业务传输线卡根据第一业务配置信息将业务数据通过第一高阶OTU端口和光纤发送给第三混合业务传输线卡；
第二混合业务传输线卡根据第一业务配置信息将业务数据通过第二高阶OTU端口和光纤发送给第四混合业务传输线卡。
在第二设备中，
第三混合业务传输线卡通过第三高阶OTU端口接收到业务数据，根据第二业务配置信息将接收到的业务数据发送给第二集中式控制单元；
第四混合业务传输线卡通过第四高阶OTU端口接收到业务数据，根据第二业务配置信息将接收到的业务数据发送给第二集中式控制单元；
当检测到所述第三高阶OTU端口的告警时，所述第二集中式控制单元将所述第四混合业务传输线卡接收到的业务数据发送给所述第二客户业务接入线卡；
当没有检测到所述第三高阶OTU端口的告警时，所述第二集中式控制单元将所述第三混合业务传输线卡接收到的业务数据发送给所述第二客户业务接入线卡。
在一种示例性实例中，将如图1所示的保护系统中的检测器设置在第三混合业务传输线卡中，将执行器设置在第二集中式控制单元中，将控制器和协议传递器设置在第三混合业务传输线卡或第二集中式控制单元中。
检测器检测到第三高阶OTU端口的告警时，将告警发送给控制器，控制器进行APS协议计算(遵循ITU-T G.873.1-OTN：线性保护)后，也就是根据工作路径的告警状态和保护属性计算出当前客户业务从工作路径接收还是从保护路径接收，发送决策结果给执行器，执行器将失效路径上承载的低阶通道业务切换到保护路径上，也就是将第四混合业务传输线卡接收到的业务数据发送给所述第二客户业务接入线卡，用保护路径来传递正常的业务信号，从而达到业务的保护。
在另一种示例性实例中，将如图1所示的保护系统中的检测器设置在第三混合业务传输线卡和第四混合业务传输线卡中，将执行器设置在第二集中式控制单元中，将控制器和协议传递器设置在第三混合业务传输线卡或第二集中式控制单元中。
检测器检测到第三高阶OTU端口和/或第四高阶OTU端口的告警时，将告警发送给控制器，控制器进行APS协议计算(遵循ITU-T G.873.1-OTN：线性保护)后，也就是根据工作路径的告警状态和保护属性计算出当前客户 业务从工作路径接收还是从保护路径接收，发送决策结果给执行器，执行器将失效路径上承载的低阶通道业务切换到保护路径上，也就是将第四混合业务传输线卡接收到的业务数据发送给所述第二客户业务接入线卡，用保护路径来传递正常的业务信号，从而达到业务的保护。

在本申请实施例中，第一客户业务接入线卡接收到业务数据后，对业务数据进行映射处理后直接下背板发送给第一集中式控制单元进行映射封装。

在本申请实施例中，第二集中式控制单元具体用于执行以下任意一个或多个：
当检测到所述第三高阶OTU端口的告警，且没有检测到所述第四高阶OTU端口的告警时，所述第二集中式控制单元将所述第四混合业务传输线卡接收到的业务数据发送给所述第二客户业务接入线卡；
当没有检测到所述第三高阶OTU端口的告警，且检测到所述第四高阶OTU端口的告警时，所述第二集中式控制单元将所述第三混合业务传输线卡接收到的业务数据发送给所述第二客户业务接入线卡；
当没有检测到所述第三高阶OTU端口的告警，且没有检测到所述第四高阶OTU端口的告警时，所述第二集中式控制单元将所述第三混合业务传输线卡接收到的业务数据发送给所述第二客户业务接入线卡。
本申请实施例通过第二混合业务传输线卡和第四混合业务传输线卡组成的保护路径实现了业务的倒换保护，由于高阶OTU端口的告警包括光层的告警和业务层面的告警，在OTN线路损坏之前进行了保护，因此，提高了故障检测的效率，并且，在不替换相关客户业务接入线卡的情况下，通过软件升级和新增混合业务传输线卡的方式实现了混合业务的保护部署，优化了保护组配置，使得保护组对外呈现简洁，便于运营维护，提高了集成度。
上述业务保护装置和业务保护系统的具体实现过程与前述实施例业务保护方法的具体实现过程相同，这里不再赘述。
