Description

同路由检测方法和装置
本申请要求于2021年11月11日提交中国国家知识产权局、申请号202111331122.5、申请名称为“同路由检测方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及光通信领域，并且更具体地，涉及一种同路由检测方法和装置。
背景技术
当前，光纤作为光通信系统中的重要传输媒介而广受关注。其中，光缆、管道、杆线等外线资源是光路网络管理的重点。当两条业务途径的光缆路由存在同缆、同沟(埋地)/同沟(架空)、同光交箱/接头盒的时候被称为同路由。
随着光缆数量倍增、光缆网错综复杂，并且光缆网经常变更(挖断、割接、新铺、改路等)等，使得光缆网实时、准确地管理非常困难。当管理面维护的地理信息系统(geographic information system，GIS)信息与真实物理GIS信息不一致的时候，就会造成规划的主备路径出现同路由。
由于同路由的两条路径在物理空间相距较近，一条路径出现故障时，通常伴随着另一条路径也同时出现故障(例如，同沟的两根光缆被挖掘机挖断)。主备路径具有同路由段后，具有很高的同时中断风险。当风险发生后，主备保护将彻底失效，无法起到保护作用，影响业务的可靠性、可用率。
因此，如何能够自适应网络动态变化、准确、快速地检测多条光路的同路由是亟待解决的问题。
发明内容
本申请实施例提供一种同路由识别检测和装置，能够自适应网络动态变化、准确、快速地检测多条光路的同路由。
第一方面，提供了一种同路由检测方法，应用于同路由检测系统，该同路由检测系统包括多个光纤传感模块、至少一个激励源终端和同路由检测单元，该多个光纤传感模块包括第一光纤传感模块和第二光纤传感模块，该至少一个激励源终端包括第一激励源终端，该方法包括：同路由检测单元接收来自第一光纤传感模块的第一扰动信息，以及接收来自第二光纤传感模块的第二扰动信息，第一扰动信息和第二扰动信息是在第一激励源终端开启激励源扰动后获取的，第一扰动信息与第一光路对应，第二扰动信息与第二光路对应，第一扰动信息和第二扰动信息分别包括扰动回波信号；同路由检测单元根据第一扰动信息和第二扰动信息确定第一激励源终端的扰动位置为第一光路和第二光路的同路由位置。
需要说明的是，该方法可以由同路由检测单元执行，或者，也可以由用于同路由检测单 元的芯片或电路执行，本申请对此不作限定。为了便于描述，下面以由同路由检测单元执行为例进行说明。
根据本申请提供的方案，在第一激励源终端开启激励源扰动后，通过接收来自不同光路的扰动信息，进行判断扰动位置即为第一光路和第二光路的同路由位置。基于主动加扰后的光纤传感数据同路由识别方法，能够快速、准确地识别两条光路是否具有同路由。
可选地，本申请同样适用于识别和检测多条光路具有同路由段。例如，存在另一扰动位置，同路由检测单元根据上述实现方式确定该另一扰动位置也为第一光路和第二光路的同路由位置。因此，可以认为这两个扰动位置形成的地理路段即为第一光路和第二光路的同路由段。
应理解，在上述实现方式中，第一网元和第二网元处分别部署第一光纤传感模块和第二光纤传感模块，即一个网元对应一个光纤传感模块。可选地，也可以是一个网元(例如，第一网元)处部署多个光纤传感模块(例如，第一光纤传感模块和第二光纤传感模块)，该网元可以根据端口(例如，光纤接口单元(fiber interface unit，FIU)端口)标识确定不同的光纤传感模块检测到的对应的扰动信息等，本申请技术方案对网元数量以及光纤传感模块的数量不作具体限定。以上仅是示例性说明，不应构成对本申请技术方案的任何限定。
还应理解，同一网元处部署的多个光纤传感模块检测的多个光路可以是同路由，也可以是不同路由，本申请对此不作具体限定。
在本申请技术方案中，扰动回波信号的采集可以理解为：利用光时域反射仪(optical time domain reflectometer，OTDR)的工作原理，监测并采集光在光纤中由于瑞利散射产生的相位信息，从而判断光纤在各个的传输特性。例如，通过检测两个光纤在激励源终端的扰动位置处的相位情况，进一步检测该两条光路在扰动位置是否具有同路由。
结合第一方面，在第一方面的某些实现方式中，第一激励源终端通过编码的方式控制激励源扰动。

示例性的，光纤传感模块在每一个检测周期(例如，0.5s)会给出一次振动检测结果(检测到振动可以标识为1、未检测到振动标识为0)。由于机械振动启停有惯性，快速(0.5s时间内)启停编码不具有操作性，本申请技术方案采用将多个连续光纤传感检测周期作为一个振动编码(振动为1，非振动为0)，振动编码可以采用两种方式：其一，振动(M个检测周期)/非振动编码(N个检测周期)时间不固定，通过控制M/N占比生成不同编码；其二，振动(M个检测周期)/非振动编码(N个检测周期)时间固定(M＝N)，采用通信编码(例如，码分多址(code division multiple access，CDMA)等)生成不同编码。
结合第一方面，在第一方面的某些实现方式中，同路由检测单元根据第一扰动信息和第二扰动信息确定第一激励源终端的扰动位置为第一光路和第二光路的同路由位置，包括：当 第一扰动信息和第二扰动信息的扰动回波信号之间的相似度大于预设阈值时，同路由检测单元确定第一激励源终端的扰动位置为第一光路和第二光路的同路由位置。

需要说明的是，同路由检测单元可以基于第一扰动信息、第二扰动信息和第三扰动信息，以判断第一光路和第二光路在激励源终端的扰动位置是否具有同路由。该实现方式的准确率能够得到进一步提高。其中，激励源终端上报的第三扰动信息与第一扰动信息、第二扰动信息中扰动时间、扰动位置理想状态下是相同的。
应理解，第一扰动信息、第二扰动信息分别是第一光纤传感模块和第二光纤传感模块监测并上报的，第三扰动信息是激励源终端直接上报的。另外，同路由检测单元可以根据第一扰动信息和/或第二扰动信息确定第一光路和第二光路分别对应的第一扰动编码和第二扰动编码，而从第三扰动信息中可以直接获取第三扰动编码。
换句话说，第一扰动信息、第二扰动信息和第三扰动信息的上报对象不同、来源不同、上报的具体形式也有所不同。
结合第一方面，在第一方面的某些实现方式中，同路由检测单元根据第一扰动信息、第二扰动信息和第三扰动信息确定第一激励源终端的扰动位置为第一光路和第二光路的同路由位置，包括：同路由检测单元根据第一扰动信息确定第一扰动编码，和/或根据第二扰动信息确定第二扰动编码；当第一扰动编码和第二扰动编码中的至少一个扰动编码与第一激励源终端的扰动编码之间的相似度大于预设阈值时，同路由检测单元确定第一激励源终端的扰动位置为第一光路和第二光路的同路由位置。

示例性的，第一激励源终端可以部署在光路的管井、光交箱、熔纤盒、架空杆等位置。
结合第一方面，在第一方面的某些实现方式中，同路由检测单元向第一光纤传感模块和第二光纤传感模块发送请求消息，该请求消息分别用于请求获取第一扰动信息和第二扰动信息。
结合第一方面，在第一方面的某些实现方式中，至少一个激励源终端包括第二激励源终端，该方法还包括：同路由检测单元接收来自第一光纤传感模块的第三扰动信息，以及接收来自第二光纤传感模块的第四扰动信息，第三扰动信息和第四扰动信息是在第二激励源终端开启激励源扰动后获取的，第三扰动信息与第一光路对应，第四扰动信息与第二光路对应，第三扰动信息和第四扰动信息包括扰动时间和扰动回波信号；同路由检测单元根据第一扰动 信息和第三扰动信息生成第一光纤地理信息系统GIS信息，以及根据第二扰动信息和第四扰动信息生成第二光纤地理信息系统GIS信息；同路由检测单元根据第一光纤GIS信息和第二光纤GIS信息匹配空间具有相近点，确定第一激励源终端的扰动位置和/或第二激励源终端的扰动位置为第一光路和第二光路的同路由位置。

具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。
光纤作为重要的通信介质，在高速、大容量、低延时等通信体统中得到了广泛应用。光纤自身比较纤细、易折断，无法直接用于设备间连接。光缆是将一定数量的光纤按照一定方式组成缆芯，光缆的基本结构包括缆芯、加强钢丝、填充物、保护套等几部分。光缆对光纤起到了强有力的保护作用，使得光纤连接设备具有工程可实现方案。
光纤通信是以光波为载体，以光纤为传输媒介的通信方式。从物理结构上看，光纤可以分为两部分，即近端光纤和远端光纤。其中，将合分波单元与光纤配线架(optical distribution frame，ODF)之间作为站点内结构，将站点内用于连接各个光学器件的光纤作为近端光纤。将ODF与传输接收端之间作为站点外结构，将站点外用于传输信号的光纤作为远端光纤。
本申请实施例可以应用于光通信系统，用于检测多条光纤之间是否具有同路由。该光通信网络包括但不限于：光传送网(optical transport network，OTN)、光接入网(optical access network，OAN)、同步数字体系(synchronous digital hierarchy，SDH)、无源光网络(passive optical network，PON)、以太网(Ethernet)、或灵活以太网(flex Ethernet，FlexE)、波分复用(wavelength division multiplexing，WDM)网络等中的任意一种或多种的组合。
下面结合图1中所示的光通信网络，对本申请提供的同路由检测的方法应用的通信系统进行示例性说明。其中，该光通信网络中可以包括多个网元以及控制器。该多个网元如图1中所示的发送设备A、发送设备B、接收设备C和接收设备D等。当然，此处的四个网元仅仅是示例性说明，实际应用场景中可以包括更多或者更少的设备，本申请对此并不作限定。
发送设备A和接收设备C之间通过光纤连接，发送设备B和接收设备D之间也通过光纤连接，光纤用于传输设备之间的数据。
控制器和光通信网络中的接收设备连接，从而获取接收设备接收到的光信号的具体信息，例如频率或相位等信息。例如，当接收设备C和接收设备D接收到发送设备A和发送设备B发送的光信号之后，对接收到的光信号进行检测，得到光信号的频率或相位等信息，并将光信号的频率或相位等信息发送至控制器。控制器用于根据接收设备采集到的光信号的具体信 息，确定两条光纤之间存在同路由。
当然，控制器也可以与光通信网络中的发送设备连接。本申请以下实施方式中，以控制器与接收设备连接为例进行示例性说明，对于控制器与发送设备之间的连接不作限定。并且，光通信网络中的网元，可以同时具备发送光信号和接收光信号的功能。因此，本申请实施例中的发送设备是指发送光信号的网元，接收设备是指接收光信号的网元。在实际应用场景中，发送设备也可以具备接收光信号的功能，接收设备也可以具备发送光信号的功能。
本申请提供的同路由检测的方法可以由控制器执行，例如软件定义网络(software defined network，SDN)控制器或路径计算单元(path computation element，PCE)等执行，也可以由光通信网络中的网元来执行，具体可以根据实际应用场景进行调整。
为便于理解本申请实施例，首先对本申请中涉及的几个术语做简单说明。
1、光纤。光纤是一种由玻璃或塑料制成的纤维，可作为光传导工具，用于传输设备之间传输数据。
2、光缆。一种通信线缆，通过其内部纤芯传播光信号实现大容量信息通信。通常，随着距离的增加，光缆的体积、重量也增加，因此，对一段光缆无法实现距离较远的设备之间的数据传输，需要将多段光缆拼接起来。并且，一段光缆内可以包括一条或多条光纤，该一条或多条光纤外部包裹有保护套管等。
示例性地，图2为一种光缆的横截面的一例示意图，其中，该光缆包括保护套管21，保护套管21内部包裹有四条光纤22，即图2中的光纤1、光纤2、光纤3和光纤4。此外，光缆内还设置有其他部件，例如，填充物以及电源线等，本申请此处对光缆和光纤之间的结构关系进行说明，对光缆所包括的其他部件不作限定。
3、光缆段。光缆中相邻的交接点或接头点之间的部分，是光缆的使用单元。
4、光传送段路径(optical transmission section trail，OTS)。指两个相邻站点之间，以两端FIU单板为起始和终止单板的路径。
5、光路。一系列首尾衔接的纤芯，是光传送段路径OTS的物理路由。
6、光纤接口单元(fiber interface unit，FIU)。指波分复用(wavelength division multiplexing，WDM)站点上的光接口单元。
7、同缆。指任意两个光路通过相同的光缆段。
8、光纤配线架ODF。用于光纤通信系统中局端主干光缆的成端和分配，可方便地实现光纤线路的连接、分配和调度。
9、光交箱。也可以称光缆交接箱，是一个无源设备，用于将大对数的光缆通过光缆交接箱分为不同方向的几个小对数光缆。
10、接头盒。也可以称为熔纤盒，用于将多段光缆连接在一起。
随着设备之间的距离的增加，光缆的体积、重量也增加。因此，一段光缆无法实现距离较远的设备之间的数据传输，需要将多段光缆拼接起来。且因一段光缆的长度有限，多段光缆之间可以通过ODF、光交箱或者接线盒等连接，也可以理解为光交箱或者接线盒等将光缆分为多段光缆段。
图3是适用本申请的一条光纤的一例示意图。如图3所示，ODF 1、接头盒、光交箱和ODF 2将发送设备与接收设备之间的光纤分为多个分段，每段光纤位于或者包裹于不同的光缆段中，如ODF 1和接头盒之间的光纤位于或者包裹于光缆段1，接头盒和光交箱之间的光 纤位于或者包裹于光缆段2，光交箱和ODF 2之间的光纤位于或者包裹于光缆段3。光缆段可以理解为两个连接点之间的一段连续光缆，这段连续的光缆中没有熔接点或者连接点。
可选地，在本申请中，可以在需要进行同路由检测的光缆段设置激励源终端，用于产生振动从而带动光纤振动。例如，结合前述图3，可以在无熔纤盒的管井、接头盒、光交箱、机房或者光缆段的任意一个位置设置激励源终端，从而使激励源终端发生振动，通过检测扰动信息从而判断不同光纤在扰动位置是否存在同路由。
光纤凭借大容量、低延时等特点成为近年来主要的通信媒介，被称作“信息高速公路”。国家、运营商、企业竞相投入大量资金、人力建设光缆网，使得光缆覆盖率呈现爆发式增长。但是，光纤本身的物理特征，例如易折、易断、怕火、怕应力，使得光纤故障成为网络的最大隐患。在光通信系统中，为了获得通信的高可靠性，通常采用主备路径保护方案，即连接两个设备的光路有多条。
图4是适用本申请的主备路径保护方案的一例示意图。如图4所示，连接设备A和设备B的光路有两条，分别是主路径和备路径。即设备A和设备B可以分别在主路径和备路径上通信。其中，当主路径出现故障的时候，可以将业务切到备路径上。该实现方式可以保证通信的可靠性，避免光纤故障引起设备之间数据传输的中断。
需要说明的是，当两条业务途径的光缆路由存在同缆、同沟(埋地)、同沟(架空)、同光交箱或接线盒时，被称为同路由。随着光缆数量倍增，光缆网错综复杂。并且，光缆网挖断、割接、新铺、改路等变更频繁，使得光缆网实时、准确地管理比较困难。当管理面维护的地理信息系统(geographic information system，GIS)信息与真实物理GIS不一致的时候，就会造成规划的主备路径出现同路由的情况。
然而，随着距离的增加，光缆的体积、重量等都随之增，对于远距离传输的设备之间，连接的光缆需要由多段光缆段拼接而成。并且，一段光缆中可能包括了多条光纤，而不同的光纤可能传输至不同的设备，可以理解为不同的光纤通往不同的方向，需要对光缆中的光纤进行分路。
连接两个站点之间通信的光纤称为通信路径，两条通信路径可能共用同一段光缆。例如，若通信路径1由光缆段1和光缆段2组成，通信路径2由光缆段2和光缆段3组成，则光缆段2为通信路径1和通信路径2共同的光缆段，共用的光缆段以下可以称为同缆段。并且，一旦通信路径1和通信路径2的同缆段出现故障，例如被挖断、弯折、挤压等，将导致通信路径1和通信路径2都出现通信质量变差、甚至中断等问题。
图5是适用本申请的主备路径同路由的一例示意图。如图5所示，设备A和设备B之间有两条光路，分别为主路径和备路径。其中，两条路径对应的光缆1和光缆2路由存在同沟(埋地)的情况，因此主路径和备路径之间形成同路由。
应理解，同路由的两条路径的典型特点是在物理空间上相距较近。当其中一条路径出现故障时，通常伴随着另一条路径也同时出现故障。例如，同沟的两根光缆被挖掘机挖断。需要说明的是，当主备路径具有同路由路段后，主备路径具有较高的同时中断的风险。当风险发生后，主备路径保护将彻底失效，无法起到保护作用，进而影响业务的可靠性和可用率。因此，为了避免该风险，一种能够快速适应网络动态变化的识别两条光路是否具有同路由的手段成为迫切需求。
当前，厂商不能自建光缆，均以租赁运营商的光缆为主。光缆资源是运营商最重要的基 础资源之一。其中，光缆资源包括光纤配线架ODF、光缆、光交、管道、杆路等，需要依靠人工进行收集、录入及核对。
由于运营商光缆量大、且一直处于动态变化(例如，新建、割接、拆旧等)，人工管理效率低。在租用光纤时，人工检测有无同缆同路由的效率低、耗时长。为了维护高准确、全面的光缆信息，需要的人力成本高、难度大。另外，获取全面、实时、准确的光缆信息很困难，甚至不可能。
图6是适用本申请的同路由检测的一例示意图。如图6的(a)所示，该应用场景中可以包括至少两个光通信设备，例如可以包括发送设备A、发送设备B、接收设备C和接收设备D。设备A和设备C之间以及设备B和设备D之间通过光纤连接。设备A和设备C之间形成光路A-C，设备B和设备D之间形成光路B-D。其中，相邻两段光缆通常采用机械连接头或熔纤的方式连接。光路A-C和光路B-D途经的光缆路由存在同缆(例如，光缆段3)、同光交箱、同接线盒。
发送设备A和接收设备C之间连接的光纤可以位于或者包裹于光缆段1、光缆段3和光缆段4中，发送设备B和接收设备D之间连接的光纤可以位于或者包裹于光缆段2、光缆段3和光缆段5。因此，光缆段3为发送设备A和接收设备C之间连接的光纤和发送设备B和接收设备D之间连接的光纤共用的光缆段。
如图6的(b)所示，该应用场景中可以包括发送设备A、接收设备C和接收设备D等，发送设备A和接收设备C之间连接的光纤可以位于或者包裹于光缆段3和光缆段4中，发送设备A和接收设备D之间连接的光纤可以位于或者包裹于光缆段3和光缆段5，因此，光缆段3为发送设备A和接收设备C之间连接的光纤和发送设备A和接收设备D之间连接的光纤共用的光缆段。
光缆虽然对光纤的起到了保护作用，但是一旦光缆出现故障(例如，被挖断、弯折或挤压等)，将会使得经过该光缆的所有光路出现故障，造成通信质量变差、甚至中断等。因此，为了提高通信的可靠性，通常采用主备保护，即连接两个设备之间的光纤有多条，当主路径出现故障时，可以将业务数据切换到备用路径上传输。
如图6的(c)所示，发送设备和接收设备之间存在由光纤组成的路径1和路径2。其中，路径1和路径2存在同缆段，若该同缆段出现故障，例如被挖断、弯折或挤压等，则导致路径1和路径2的传输均中断，使发送设备和接收设备之间的数据传输受到影响，甚至不能传输数据。因此，为了避免主备路径同缆的风险，需要快速、准确且能够适应网络动态变化地实现同缆段的识别。然而，若由人工记录光缆途径的设备信息，需要耗费较大的人力成本，且当光缆中的某些设备或者光缆发生变化或更新时，需要人工进行维护，可能人工无法及时记录更新的设备或者光缆，导致两条光纤之间的共用的光缆段无法及时记录，影响设备之间的数据传输。
然而，当主路径和备用路径同路由时，若共用的光缆段出现故障，例如被挖断、弯折或挤压等，则导致两个设备之间无法传输数据，主备保护失效，主路径和备用路径无法起到保护作用。
应理解，一根光纤可以经过一段或多段光缆。如果两根光纤经过相同的一段或多段光缆时，可以通过光时域反射仪(optical time domain reflectometer，OTDR)检测两根光纤的光缆特征是否相近，进而确定两根光纤的同缆概率。
然而，该实现方式只能检测两根光纤是否同缆，而不能检测同沟/同杆、同路由等场景，具有一定的局限性。
当前，采用人工结合巡缆辅助工具的方式，提供了一种光缆巡缆手段。其中，巡线分析仪接入巡缆光纤，光纤配线架ODF与管井1、管井2、...、管井n通过光纤连接，移动终端用于显示巡缆分析仪回波信号。
在该实现方式中，人工沿路敲击光缆恢复光缆路由，建立光缆路由数据库。由于光纤传感对振动非常敏感，当锤子敲击井盖(例如，管井1、管井2、...、管井n)时，可以在光纤传感回波信号中看到敲击信号。通过在巡缆点反复敲击，且观察移动终端上显示的巡缆分析仪回波信号，来判断移动终端显示的信号是否为该巡缆点处敲击信号。如果移动终端确认在该巡缆点出现敲击信号，则标记光缆经过该巡缆点。如果移动终端未出现信号，则无法确定光缆是否经过该巡缆点。
然而，考虑到自然界中类似敲击的扰动很多，采用敲击方式容易受到干扰，出现误检测的情况。而且，这一敲击方式需要操作者有较为丰富的辨别经验，操作难度大。由于需要人工到场，导致巡缆效率低、人工成本高等问题。另外，在光缆变更后，仍然需要人工到场，更新存在延迟且容易出现漏更新、数据更新慢等。总之，整体方案准确率低、效率不高。最后，人工敲击进行同路由检测需要在两个站点同时检测，并且敲中同路由点，当前方案几乎是不可行的。
综上所述，路由分离是影响光通信可靠性的关键动态因素，因此受到高度重视。实现路由分离，是主备路径保护起到增强可靠性的前提。但是，由于光缆GIS信息主要通过人工收集、录入以及核对，效率低、维护成本高，并且光缆更新(例如，新建、割接、拆旧)不及时将无法保证业务实时、动态地调整，容易发生大量同缆单点故障，造成重大损失。
有鉴于此，本申请提供一种准确、快速、能够适应网络动态变化的同路由检测方法，在同路由检测系统中配置一个有编码的加扰终端，使得同路由中所有的光纤将感知到扰动信号。并通过光纤传感接收光纤传感信号，分析光纤中是否包含特定扰动信号来进行同路由检测。

图7是适用本申请的同路由检测系统装置的一例示意图。如图7所示，该系统装置包括光纤传感模块、同路由共享风险链路组(shared risk link groups，SRLG)检测单元和激励源终端。具体地，在同路由点(例如，共光交箱、熔纤盒、同杆等)或者同路由段(例如，同沟或同架空段)放置一个有编码的加扰终端时，同路由中所有的光纤将感知到该扰动信号。同时，在网元处部署光纤传感器来接收光纤传感信号，通过分析光纤中是否包含特定扰动信号来进行同路由检测。另外，在网络某一节点(例如，某个网元、网络控制引擎(network cloud engine，NCE)、网管等)上部署同路由SRLG检测单元，来实现同路由SRLG检测。
光纤传感模块主要包括探测模块和数据分析模块。其中，探测模块用于获取光纤各点的扰动回波信号。数据分析模块用于通过分析获取的光纤各点的扰动回波信号，确定什么位置存在扰动。如果有扰动，则将扰动回波信号上报同路由SRLG检测单元。
需要说明的是，分布式光纤传感器可以实现振动和声场连续分布式探测的传感技术。它利用窄线宽激光器在光纤中激发的相干瑞利散射对应变变化高度敏感的特性，结合反射计原理，对与光纤相互作用的环境振动与声场信息进行长距离、高时空精度的感知。。
同路由SRLG检测单元主要包括控制或管理模块、数据管理模块、SRLG检测模块、SRLG管理模块等。其中，控制或管理模块用于控制或管理光纤传感和/或激励源终端，负责使能、下发配置、采集光纤传感和/或激励源终端的数据等。数据管理模块负责采集数据存储等。SRLG检测模块用于根据光纤传感上报的扰动回波信号、以及激励源终端上报的激励扰动信息、时间等，进行匹配是否存在两个扰动回波信号满足相似度阈值。例如，根据扰动回波之间的相似度，以及扰动回波与激励源扰动信息之间的相似度大于预设阈值，进行双重保障同路由SRLG检测准确率。SRLG管理模块用于管理SRLG新增、失效、变更等。
激励源终端具有编码的扰动的基本功能，可以附带支持上报位置GIS信息、时间信息、可远程编码控制等功能。其中，激励源可以采用机械波和声波，二者特点或实现编码方式包括机械振动波和声波。机械振动波的频率范围通常小于150Hz，可以采用单频时域编码。声波的频率范围通常为20-20000Hz，可以采用多频率组合编码。例如，音乐等，不同音乐包含不同声谱。
图8是本申请实施例提供的一种同路由检测方法800的一例示意图，该方法应用于同路由检测系统，该同路由检测系统包括多个光纤传感模块、至少一个激励源终端和同路由检测单元，该多个光纤传感模块包括第一光纤传感模块和第二光纤传感模块，该至少一个激励源终端包括第一激励源终端，具体实现步骤包括：
S810，第一光纤传感模块和第二光纤传感模块获取第一扰动信息和第二扰动信息。其中， 第一扰动信息和第二扰动信息是在第一激励源终端开启激励源扰动后获取的，第一扰动信息与第一光路对应，第二扰动信息与第二光路对应，第一扰动信息和第二扰动信息分别包括扰动回波信号。
应理解，在上述实现方式中，第一网元和第二网元处分别部署第一光纤传感模块和第二光纤传感模块，即一个网元对应一个光纤传感模块。可选地，也可以是一个网元(例如，第一网元)处部署多个光纤传感模块(例如，第一光纤传感模块和第二光纤传感模块)，该网元可以根据端口(例如，光纤接口单元(fiber interface unit，FIU)端口)标识确定不同的光纤传感模块检测到的对应的扰动信息等，本申请技术方案对网元数量以及光纤传感模块的数量不作具体限定。以上仅是示例性说明，不应构成对本申请技术方案的任何限定。
还应理解，同一网元处部署的多个光纤传感模块检测的多个光路可以是同路由，也可以是不同路由，本申请对此不作具体限定。
在本申请技术方案中，扰动回波信号的采集可以理解为：利用光时域反射仪(optical time domain reflectometer，OTDR)的工作原理，监测并采集光在光纤中由于瑞利散射产生的相位信息，从而判断光纤在各个的传输特性。例如，通过检测两个光纤在激励源终端的扰动位置处的相位情况，进一步检测该两条光路在扰动位置是否具有同路由。
需要说明的是，相位OTDR系统作为一种分布式光纤传感系统，通常使用窄线宽脉冲激光器作为传感光源，可以响应相位调制。其中，光脉冲从光纤的一端注入，用光探测器探测后向瑞利散射光。注入光纤中的光是强相干的，因此该传感系统的输出是后向瑞利散射光相干干涉的结果。相位OTDR通过测量注入脉冲与接收到的信号之间的时间延迟得到扰动的位置。当光纤线路发生扰动时，相应位置光纤的折射率及长度将会发生变化，这将导致该位置光相位的变化。因为扰动位置的散射光传输到探测器经历的是周期性的相位变化，因此最终相位的变化由于干涉作用将导致光强发生变化，并与扰动位置对应。相位OTDR具有灵敏度高、定位精度高、数据处理简单等优点。
作为示例而非限定，第一激励源终端通过编码的方式控制激励源扰动。
示例性的，采用编码的方式控制激励源终端是否启动。例如，当码字为0，用于指示停止激励源终端的扰动。当码字为1，用于指示开始激励源终端的扰动。以上仅是示例性说明，不应构成对本申请技术方案的任何限定。
在本申请实施例中，第一激励源终端的激励源采用机械波或声波。
作为示例而非限定，第一激励源终端的扰动编码的生成方式包括：基于单频时域编码的机械波编码方式和/或基于多频率组合编码的声波编码方式。
示例性的，光纤传感模块在每一个检测周期(例如，0.5s)会给出一次振动检测结果(检测到振动可以标识为1、未检测到振动标识为0)。由于机械振动启停有惯性，快速(0.5s时间内)启停编码不具有操作性，本申请技术方案采用将多个连续光纤传感检测周期作为一个振动编码(振动为1，非振动为0)，振动编码可以采用两种方式：其一，振动(M个检测周期)/非振动编码(N个检测周期)时间不固定，通过控制M/N占比生成不同编码；其二，振动(M个检测周期)/非振动编码(N个检测周期)时间固定(M＝N)，采用通信编码(例如，码分多址，CDMA)生成不同的编码。
在本申请实施例中，第一光纤传感模块和第二光纤传感模块分别部署在第一网元和第二网元，第一激励源终端部署在第一光路和/或第二光路的任意位置。

对应的，同路由检测单元分别接收来自第一光纤传感模块和第二光纤传感模块的第一扰动信息和第二扰动信息。
S830，同路由检测单元根据第一扰动信息和第二扰动信息确定第一激励源终端的扰动位置为第一光路和第二光路的同路由位置。

示例性的，同路由检测单元收集一段时间数据后，启动同路由检测。具体同路由检测方法包括：记录第一网元采集的扰动回波为data1，第二网元采集的扰动回波为data2，回波相似性用r来表示，即：
r(data1，data2)＝cov(data1，data2)/sqrt(var(data1)*var(data2))
其中，r(a，b)表示a和b相关系数，cov(a，b)表示a和b协方差，var(a)表示a的方差。
当r大于预设阈值(threshold)时，例如0.8，则认为该扰动位置为第一光路和第二光路的同路由位置。
在一种可能的实现方式中，同路由检测单元接收来自第一激励源终端的第三扰动信息，该第三扰动信息包括以下至少一种信息：第一激励源终端开启激励源扰动的扰动时间、第一激励源终端所在的位置、第一激励源终端的扰动编码；同路由检测单元根据第一扰动信息、第二扰动信息和第三扰动信息确定第一激励源终端的扰动位置为第一光路和第二光路的同路由位置。
需要说明的是，同路由检测单元可以基于第一扰动信息、第二扰动信息和第三扰动信息，以判断第一光路和第二光路在激励源终端的扰动位置是否具有同路由。该实现方式的准确率能够得到进一步提高。其中，激励源终端上报的第三扰动信息与第一扰动信息、第二扰动信息中扰动时间、扰动位置理想状态下是相同的。
应理解，第一扰动信息、第二扰动信息分别是第一光纤传感模块和第二光纤传感模块监测并上报的，第三扰动信息是激励源终端直接上报的。另外，同路由检测单元可以根据第一扰动信息和/或第二扰动信息确定第一光路和第二光路分别对应的第一扰动编码和第二扰动编码，而从第三扰动信息中可以直接获取第三扰动编码。
换句话说，第一扰动信息、第二扰动信息和第三扰动信息的上报对象不同、来源不同、上报的具体形式也有所不同。
进一步地，在该实现方式中，同路由检测单元根据第一扰动信息确定第一扰动编码，和/或根据第二扰动信息确定第二扰动编码；当第一扰动编码和第二扰动编码中的至少一个扰动编码与第一激励源终端的扰动编码之间的相似度大于预设阈值时，同路由检测单元确定第一激励源终端的扰动位置为第一光路和第二光路的同路由位置。
示例性的，同路由检测单元收集一段时间数据后，启动同路由检测。具体同路由检测方法包括：记录第一网元提取的扰动编码为code1，第二网元提取的扰动编码为code2，激励源终端上报的扰动编码为code0，编码相似性用levenshtein距离来表示，即：
levab(code1，code2)＝1-ch<code1，code2>/max(len_code1，len_code2)
levab(code1，code0)＝1-ch<code1，code0>/max(len_code1，len_code0)
levab(code0，code2)＝1-ch<code0，code2>/max(len_code0，len_code2)
其中levab(a，b)表示编码a和b的levenshtein距离，ch<a，b>表示从编码a变成b的最小操作数，len_a表示编码a的长度。
当上述3组levab都大于预设阈值(threshold)时，例如0.8，则认为该扰动位置为第一光路和第二光路的同路由位置。
示例性的，同路由检测单元根据第一扰动编码code1和第二扰动编码code2之间的编码相似性levab(code1，code2)＝1-ch<code1，code2>/max(len_code1，len_code2)大于预设阈值，即可确定激励源终端的扰动位置即为第一光路和第二光路的同路由位置。
在该实现方式中，基于编码检测能够有效抵抗环境干扰，提高同路由检测的效率和准确率。
需要说明的是，上述根据扰动编码和/或扰动回波判断多条光路在激励源终端的扰动位置是否具有同路由的方式，可以独立使用，也可以组合使用，本申请技术方案对此不作具体限定。
需要说明的是，本申请技术方案同样适用于识别和检测多条光路具有同路由段。例如，存在另一扰动位置，同路由检测单元根据上述实现方式确定该另一扰动位置也为第一光路和第二光路的同路由位置。因此，可以认为这两个扰动位置形成的地理路段即为第一光路和第二光路的同路由段。
在另一种可能的实现方式中，至少一个激励源终端包括第二激励源终端。
首先，第一光纤传感模块和第二光纤传感模块分别向同路由检测单元发送第三扰动信息和第四扰动信息。对应的，同路由检测单元分别接收来自第一光纤传感模块和第二光纤传感模块的第三扰动信息和第四扰动信息，
其中，第三扰动信息和第四扰动信息是在第二激励源终端开启激励源扰动后获取的，第三扰动信息与第一光路对应，第四扰动信息与第二光路对应，第三扰动信息和第四扰动信息包括扰动时间和扰动回波信号。

最后，同路由检测单元根据第一光纤GIS信息和第二光纤GIS信息匹配空间具有相近点，确定第一激励源终端的扰动位置和/或第二激励源终端的扰动位置为第一光路和第二光路的同路由位置。
其中，光纤地理信息系统GIS信息可以理解为光纤的真实地理位置。例如，光纤所在的经纬度。
在该实现方式中，通过确定多条光路上部署的多个激励源终端，并检测多条光路在多个扰动位置是否具有同路由，来实现全网自动同路由的识别，支持多点同时检测，效率倍增。
在又一种实现方式中，同路由检测单元接收来自第一光纤传感模块的至少一个扰动信息， 该至少一个扰动信息与第一范围内的至少一个激励源终端一一对应，第一范围是以距离目标断纤点最近的第一激励源终端为圆心，半径为R的范围，目标断纤点是第一光纤传感模块在第一光路检测到的断纤位置；同路由检测单元根据第一范围内至少一个扰动信息确定从第一激励源终端下一跳的至少一个第二激励源终端，至少一个第二激励源终端是第一光路上的激励源终端。
进一步地，同路由检测单元接收来自第一光纤传感模块的至少一个扰动信息，该至少一个扰动信息与第i范围内的至少一个激励源终端一一对应，第i范围是以第i激励源终端为圆心，半径为R的范围，第i激励源终端是第一光路上第i-1激励源终端的下一跳的激励源终端，i为大于或等于2的整数；同路由检测单元根据第i范围内至少一个扰动信息确定从第i激励源终端下一跳的至少一个第i+1激励源终端，至少一个第i+1激励源终端是第一光路上距离第三网元最近的激励源终端，第三网元与第一网元是第一光路的起始位置和结束位置，第一光纤传感模块部署在第一网元；同路由检测单元基于i+1个激励源终端更新第一光路的同路由。
在该实现方式中，提供了一种在断纤或割接场景下，同路由检测以及更新的方法。
示例性的，网元A和网元B之间形成第一光路，当光纤发生中断时，根据位置可以检测到距离断纤点最近的管井或光交箱为a点，那么以a点为圆心，R为半径的范围内启动激励源终端扰动，网元A处的光纤传感模块可以监测并采集到一个或多个扰动信息，可以确定该一个或多个扰动信息对应的一个或多个激励源终端是部署在该第一光路上的。然后，再启动以该一个或多个激励源终端为圆心，R为半径的范围内的所有激励源终端，对应的，网元A处的光纤传感模块继续监测并采集一个或多个扰动信息。依次监测并采集扰动信息，直至形成网元A与网元B之间的第一光路的最新路由。
综上所述，本申请实施例提供一种同路由识别检测和装置，在第一激励源终端开启激励源扰动后，通过接收来自不同光路的扰动信息，进行判断扰动位置即为第一光路和第二光路的同路由位置。该方法能够自适应网络动态变化、准确、快速地检测多条光路的同路由。
图9是适用本申请的基于机械波的单点振动同路由SRLG检测系统的一例示意图。如图9所示，该系统装置包括光纤传感模块、同路由SRLG检测单元和机械振动激励源终端。
示例性的，网元A1和网元B1、以及网元A2和网元B2之间分别形成一条光路，两条光路途经的光缆路由存在同路由点或同路由段。在同路由点或者同路由段放置一个有编码的机械振动激励源终端，同路由中所有的光纤会感知到该机械振动激励源终端的扰动信号。同时，在网元A1、A2、B1和B2处分别部署光纤传感器来接收光纤传感信号，用于分析光纤中是否包含特定扰动信号，进而进行同路由检测。另外，在网络某一节点上部署同路由SRLG检测单元，来实现同路由SRLG检测。

需要说明的是，光纤传感模块每一个检测周期(例如，0.5s)会给出一次振动检测结果(例如，检测到振动可以标识为1、未检测到振动标识为0)。由于机械振动启停有惯性，快速(0.5s时间内)启停编码不具有操作性。因此，本申请实施例将多个连续光纤传感检测周期作为一个扰动编码(例如，扰动为1，非扰动为0)。具体的机械振动激励源终端的扰动编码#0可以采用以下两种方式：

S1050，同路由SRLG检测单元根据第一信息和第二信息确定扰动位置为第一光路和第二光路的同路由位置。
示例性的，同路由SRLG检测单元在收集一段时间数据后(例如，第二信息)，启动同路由SRLG检测。基于编码相似度匹配算法，同路由检测单元根据第一扰动信息和/或第二扰动信息可以确定第一扰动编码和/或第二扰动编码，进而通过判断第一扰动编码和/或第二扰动编码之间相似度是否大于预设阈值，0或者，通过判断第一扰动编码和/或第二扰动编码与激励源终端上报的扰动编码#0之间的相似度是否大于预设阈值，从而确定在扰动位置第一光路与第二光路是否存在同路由，该实现方式能够双重保障同路由SRLG检测的准确率。
示例性的，记录网元A1提取扰动编码为code1，网元A2提取扰动编码为code2，机械振动激励源终端的扰动编码为code0。其中，编码相似性用levenshtein距离来表示：

levab(code1，code0)＝1-ch<code1，code0>/max(len_code1，len_code0)
levab(code2，code0)＝1-ch<code2，code0>/max(len_code2，len_code0)
其中，levab(a，b)表示编码a，b的levenshtein距离，ch<a，b>表示从编码a变成b的最小操作数，len_a表示编码a的长度。
如果上述3组相似性levab都大于预设阈值threshold(例如，0.8)，即当第一扰动编码和第二扰动编码之间相似性大于0.8，和/或第一扰动编码和第二扰动编码，以及激励源终端的扰动编码#0之间相似性大于0.8时，则认为在该检测点(激励源终端的扰动位置)存在同路由SRLG。
总之，基于机械波编码的同路由SRLG检测方法，能够自动识别同缆风险，保障业务的可靠性。引入编码，可以支持多点同时检测，提升检测效率。基于编码检测可以有效克服环境干扰，通过多次检测还可以提升检测结果的准确率。
