具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例只是本发明中一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例一：
本实施例的目的在于，提供一种在波分光传输系统中防止光纤错连的方法，使得当系统中出现与规划波道不一致的情况，能够及时的被检测出来并可产生告警，且不需要测试人员逐个站点的通过测试仪表进行手动测试，测试效率、准确率更好，测试成本更低。
在对网元内网元间的物理光纤进行连接时，一般都会根据波道规划图进行连接，且在连接过程中对于一些特别明显的连接错误，很容易被检测出来，例如，在线路板上收、发两端光纤接反，则网络管理服务器会上报输入无关告警。但是，对于一些连接错误并不是网络管理服务器检测到的，例如合分波板上端口对应关系连接错误时，或者错连的两根光纤恰好是同一映射方式的时候，网络管理服务器是检测不到的。对此，本实施例的光纤连接检测方法，在网络侧，其执行过程参见图1所示，包括：
S101：根据波道规划图确定业务在网元之间的传输路径，网元之间进行物理光纤连接时依据所述波道规划图进行连纤。也即确定业务传输路径时采用的波道规划图与网元之间进行实际的光纤连接时采用的波道规划图相同。
S101中所述的波道规划图的制定可以采用现有任意的方式。S101中具体可以是网络管理服务器根据波道规划图确定业务在网元之间的传输路径。根据波道规划图在网络管理服务器上进行波分设备的网元和网元间的连纤操作，一般可以采用端到端的搜索业务方式进行连纤处理，该过程参见图2所示，包括：
S201：网络管理服务器上设置业务路径上端口、单板的业务映射；
S202：根据波道规划图进行网元间的连纤；
S203：根据波道规划图进行网元内的连纤；
S204：根据业务路径上的端口、单板的业务映射确定该业务的传输路径。
应当理解的是，本实施例中S101并不限于由网络管理服务器执行。
S102：生成测试校验码，并通过传输路径上发送端网元上对应的业务发送端口，将测试校验码发送给传输路径上接收端网元上对应的业务接收端口，并将测试检验码配置在所述业务接收端口上。
通过图2所示的过程，可以直接计算确定业务传输路径上的发送端网元，以及该发送端网元上该业务的业务发送端口，并可以确定传输路径上的接收端网元以及该接收端网元上该业务的业务接收端口，同时可以确定发送端网元与接收端网元之间的路径。且S102的执行过程也可以是由网络管理服务器执行，网络管理服务器在确定好传输路径之后，生成测试校验码，该测试校验码是一个期望值，如果业务发送接口和业务接收接口之间在网络管理服务器上的光纤连接没错，且在实际物理连接过程中的物理光纤连接也没有出错，业务接收端口上收到的实际校验码与测试校验码一致；否则，就会导致二者不一致，从而检测出光纤连接错误。
S103：接收上述接收端网元在业务接收端口接收到的实际校验码与测试校验码不匹配时发送的告警信息。
本实施例中，接收端网元的业务接收端口接收到的实际校验码与之前配置的测试检验码不一致时，则表明业务发送接口和业务接收接口之间在网络管理服务器上的光纤连接，或在实际物理连接过程中的物理光纤连接出错了，会向网络侧发送告警信息。
本实施例中，将测试校验码发送给对应的业务接收端口时，具体可以将该测试校 验码携带在业务帧中随业务帧一起发给接收端网元，这样可以尽可能减少开销，提升资源利用率。
应当理解的是，本实施例中的测试检验码的生成规则可以用户自定义，也可以有网络管理服务器随机生成，或者通过其他规则进行生成。本实施例中考虑到业务帧中有用于传递光层流向的踪迹字节，其中用户自定义的字段有32个字节只涉及到监测业务流向，并无其他实际作用。因此，本实施例中具体可以将该测试校验码携带在业务帧的踪迹字节中，随业务帧一起发给接收端网元。此时本实施例中生成的测试校验码可以为网络管理服务器生成的32字节的随机校验码序列。
当然，理论上本实施例中的测试校验码的长度并不限于32字节，只要其能唯一标识各业务路径且小于等于32字节即可。
网络管理服务器生成好测试校验码之后，将其发给接收端网元在接收端网元上对应的业务接收接口进行配置，作为期望的校验码，并将其发给发送端网元的业务板上对应的业务发送端口，以供业务板将该测试校验码写入业务帧的踪迹字节中。业务板可以在每一个业务帧中都写入测试校验码，也可以根据实际测试需求仅在前面的一部分中写入测试校验码。
对于接收端网元侧，本实施例中的光纤连接检测方法执行过程参见图3所示，包括：
S301：将发给接收端网元的业务接收端口的测试检验码配置在该业务接收端口上。
S301中的测试校验码可以是网络管理系统发给接收端网元的，且可以由接收端网元的控制板将测试检验码配置在接收端网元对应的业务接收端口上。
S302：提取发送端网元的业务发送端口发送给业务接收端口的实际校验码。
本步骤中的实际校验码是指业务接收端口实际从业务发送端口接收到的测试校验码。本实施例中测试校验码可以随业务帧发给接收端网元的业务接收接口，因此提取发送端网元的业务发送端口发送给业务接收端口的实际校验码包括：
从业务发送端口向业务接收端口发送的业务帧的踪迹字节中提取实际校验码。
S303：在业务接收端口的实际校验码与之前配置的测试校验码不匹配时向网络侧发送告警信息。
该步骤中，具体可以由接收端网元的控制板完成匹配控制，该过程参见图4所示， 包括：
S401：控制板判断业务接收端口接收到的实际校验码与预先配置的测试校验码是否一致，如否，转至S402；否则，转至S404；
S402：控制板向网络侧的网络管理服务器发送告警信息；
S403：网络管理服务器接收到告警信息后，产生提示告警。
S404：光纤连接无错误。
本实施例提供的在波分光传输系统中防止光纤错连的方法，可以在系统中出现与规划波道不一致的情况，能够及时的被检测出来并可产生告警，且不需要测试人员逐个站点的通过测试仪表进行手动测试，测试效率、准确率更好，测试成本更低。
实施例二：
本实施例提供了一种网络管理服务器，参见图5所示，包括：
路径确定模块51，用于根据波道规划图确定业务在网元之间的传输路径,所述网元之间进行物理光纤连接时依据所述波道规划图进行连纤。
本实施例中波道规划图的制定可以采用现有任意的方式。路径确定模块51根据波道规划图在网络管理服务器上进行波分设备的网元和网元间的连纤操作，可以采用端到端的搜索业务方式进行连纤处理，在此不再赘述。
测试处理模块52，用于生成测试校验码并通过传输路径上发送端网元上对应的业务发送端口发送给传输路径上接收端网元上对应的业务接收端口，以及将测试检验码配置在所述业务接收端口上；
报警模块53，用于接收上述接收端网元在所述业务接收端口接收到的实际校验码与所述测试校验码不匹配时发送的告警信息。
接收端网元的业务接收端口接收到的实际校验码与之前配置的测试检验码不一致时，则表明业务发送接口和业务接收接口之间在网络管理服务器上的光纤连接，或在实际物理连接过程中的物理光纤连接出错了，会向网络侧发送告警信息，网络侧的报警模块53则会收到该告警信息。
本实施例中，测试处理模块52将测试校验码发送给对应的业务接收端口时，具体可以将该测试校验码携带在业务帧中随业务帧一起发给接收端网元，这样可以尽可能减少开销，提升资源利用率。本实施例中的测试检验码的生成规则可以用户自定义，也可以有网络管理服务器随机生成，或者通过其他规则进行生成。本实施例中考虑到 业务帧中有用于传递光层流向的踪迹字节，其中用户自定义的字段有32个字节只涉及到监测业务流向，并无其他实际作用。因此，本实施例中测试处理模块52具体可以将该测试校验码携带在业务帧的踪迹字节中，随业务帧一起发给接收端网元。此时本实施例中测试处理模块52生成的测试校验码可以为2字节的随机校验码序列。理论上本实施例中的测试校验码的长度并不限于32字节，只要其能唯一标识各业务路径且小于等于32字节即可
测试处理模块52生成好测试校验码之后，将其发给接收端网元在接收端网元上对应的业务接收接口进行配置，作为期望的校验码，并将其发给发送端网元的业务板上对应的业务发送端口，以供业务板将该测试校验码写入业务帧的踪迹字节中。业务板可以在每一个业务帧中都写入测试校验码，也可以根据实际测试需求仅在前面的一部分中写入测试校验码。
本实施例中的路径确定模块51、测试处理模块52以及报警模块53的上述功能可以由网络管理服务器的控制器或处理器实现，各模块可以构造于该控制器或处理器内。
参见图6所示，本实施例提供的接收端网元包括：
配置模块61，用于接收向业务接收端口发送的测试检验码并配置在该业务接收端口；
提取模块62，用于提取发送端网元的业务发送端口发送给所述业务接收端口的实际校验码；该实际校验码是指业务接收端口实际从业务发送端口接收到的测试校验码。本实施例中测试校验码可以随业务帧发给接收端网元的业务接收接口，因此提取模块62可以从业务发送端口向业务接收端口发送的业务帧的踪迹字节中提取实际校验码。
匹配模块63，用于在提取的实际校验码与之前配置的测试校验码不匹配时发送告警信息。本实施例中具体的报警方式在此不再赘述。
本实施例中的配置模块61、提取模块62以及配置模块63的功能可以由接收端网元控制板上的微处理器实现，各模块具体可以构造于该微处理器中。
基于本实施例提供的网络管理服务器和接收端网元，可以在系统中出现与规划波道不一致的情况，能够及时的被检测出来并可产生告警，不需要测试人员逐个站点手动测试，可以大大降低测试时间和人力成本，同时可避免测试结果受人为因素影响； 同时在开局初期就能把光纤错连的情况完全检测出来，达到了保障工程顺利开通的效果，提升了工作效率
实施例三：
为了更好理解的本发明，本实施例结合一种具体的应用场景对本发明做进一步示例说明。
参见图7所示的组网，该图中省略了网元中一些不影响对本发明方案进行描述的板件。图7中的发送端网元包含依次连接的第一光转换单元、光合波器、第一光纤放大器；发送端网元包含依次连接的第二光纤放大器、光分波器以及第二光转换单元。假设业务从第一光转换单元开始，原计划是作为80波系统的第一波和第二波进行合分波传输。首先第一光转换单元发出来的光会以192.1/192.2波长接入到光合波器上，经过第一光纤放大器上到实际的光路上。光缆通过一个长距离传输到达接收端网元，在接收端网元上再经过第二光纤放大器，被接到光分波器后，业务以192.1/192.2波长下路到第二光转换单元，从而完成了一个完整的业务传输。为方便描述，我们把虚线左侧的发送端网元命名A，虚线右侧的接收端网元命名B，具体过程如下：
1.按照规划，A站点第一光转换单元输出光纤分别连接到A站点光合波器单板的光口1和光口2，A站点光合波器单板输出口接到第一光纤放大器单板的输入口上实际光纤线路。该条光纤传递到B网元后接到第二光纤放大器单板输入口，经放大后从输出口出来接到光分波器单板输入口，从光分波器单板的第1输出口和第2输出口出来的光纤接到第二光转换单元，完成了一个业务的传递。假设从光分波器输出口出来的1/2口接反了，由于光分波器单板收光是出波的，所以网络管理服务器上不会有光路方面的告警。
2.根据规划，进行网络管理服务器上网元间连纤，注意，这里是网络管理服务器上的操作。网络管理服务器上认为规划的有两条业务，一条是以192.1波长承载的，一条是以192.2波长承载的，其中以192.1为例，业务流向是A点第一光转换单元的第1输出口到光合波器的第1输入口，到第一光纤放大器，到B点第二光纤放大器，到光分波器的输入口，由光分波器的第1输出口到第二光转换单元的第1口上。在网络管理服务器连纤同时在A网元第一光转换单元的第1输出口(也即发送端网元的业务发送端口)发出去的踪迹字节里网络管理服务器随机生成一个随机序列，比如00011112222，由于网络管理服务器连纤的时候是可以判断处这一条业务上下游关系 的，所以同时也会在B站点的第二光转换单元的第1口(也即接收端网元的业务接收端口)收口设置一个踪迹字节的期望值00011112222。同理，A站点第一光转换单元的第2输出口发一个11100002222，B站点第二光转换单元的第2口收设置一个期望值11100002222。
3.由于步骤1实际连纤和步骤2网元连纤是没对应的，那么我们很容易能知道，B站点第二光转换单元的第1口实际收到的是11100002222而期望值是00011112222，第二光转换单元的第2口收到的是00011112222而期望值是11100002222，这个时候我们根据判断这个值的不同由网络管理服务器上报一个告警以提示连纤与规划不符。
4.根据这样提示的告警，很容易就能发现光纤错连，从而针对该问题做修改。
本实施例提供的网络管理服务器和接收端网元，可以在实际光纤连接出现与规划波道不一致时及时检测出来并可产生告警，不需要测试人员逐个站点手动测试，可以大大降低测试时间和人力成本，同时可避免测试结果受人为因素影响；同时在开局初期就能把光纤错连的情况完全检测出来，达到了保障工程顺利开通的效果，提升了工作效率。
显然，本领域的技术人员应该明白，上述本发明实施例的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在计算机存储介质(ROM/RAM、磁碟、光盘)中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。所以，本发明不限制于任何特定的硬件和软件结合。
以上内容是结合具体的实施方式对本发明实施例所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
工业实用性
本发明实施例提供的技术方案可以应用于波分光传输领域。根据本发明实施例提供的光纤连接检测方法、网络管理服务器、接收端网元及存储介质，在根据波道规划图将网元内以及网元之间的物理光纤连接好之后，根据波道规划图确定业务在网元之间的传输路径,然后生成测试校验码，并通过确定的传输路径上发送端网元上对应的业务发送端口，将测试校验码发送给传输路径上接收端网元上对应的业务接收端口，并将测试检验码配置在业务接收端口上。然后在网元接收端提取发送端网元的业务发送端口发送给业务接收端口的实际校验码，将其与业务接收端口配置的测试校验码进行匹配，当二者不配时，表明这一条业务路径的物理光纤连接存在问题，自动告警。与现有技术相比，不需要测试人员逐个站点手动测试，可以大大降低测试时间和人力成本，同时可避免测试结果受人为因素影响；同时在开局初期就能把光纤错连的情况完全检测出来，达到了保障工程顺利开通的效果，提升了工作效率。
