一种ONU数据的采集方法、装置及系统
相关申请的交叉引用
本公开要求于2022年07月28日提交的申请号为202210898721.3、名称为“一种ONU数据的采集方法、装置及系统”的中国专利申请的优先权，该中国专利申请的全部内容通过引用全部并入本文。
技术领域
本申请涉及通信技术领域，特别是涉及一种ONU数据的采集方法、装置及系统。
背景技术
在工业PON(Passive Optical Network，无源光纤网络)的场景下，OLT(optical line terminal，光线路终端)下挂各个厂商的ONU(Optical Network Unit，光网络单元)，OLT需要对ONU进行数据采集，以监控整个网络的质量。
相关技术中，OLT通过OMCI(ONU Management and Control Interface，光网络单元管理控制接口)协议采集ONU数据。具体的，通过OMCI协议发送请求数据，随后获取ONU返回的数据，并进行解析。
通常OLT下挂多个ONU，在OMCI协议中，定义轮询方式来请求ONU数据，即OLT依次向每个ONU发送数据请求，然后接收各个ONU反馈的数据。
然而，OLT需要对接收到的ONU数据进行解析，并进行编码格式转换，然后再发送到上层采集平台，并且轮询请求的方式性能较低。上述两方面原因导致整个数据采集过程耗时较多，现网基本在5分钟以上时间粒度，无法满足工业场景秒级采集的用户需求。
此外，工业场景下用户可能会使用不同厂商的ONU，但目前OLT不支持异厂商ONU自定义的OMCI报文，即出现OLT与异厂商ONU无法适配的情况，导致无法采集异厂商ONU的数据。
发明内容
本申请实施例的目的在于提供一种ONU性能数据的采集方法及系统，以实现秒级粒度高效采集ONU数据。具体技术方案如下：

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员基于本申请所获得的所有其他实施例，都属于本申请保护的范围。
为了解决现有技术中，OLT采集ONU数据耗时较多的技术问题，本申请实施例提供了一种ONU数据的采集方法、装置及系统。
参见图1，图1为本申请实施例提供的ONU数据的采集方法的一种流程示意图，该方法应用于ONU，如图1所示，方法可以包括以下步骤：
S101：接收光线路终端OLT发送的采集请求。
本申请实施例中，不再采用基于OMCI协议的轮询方式采集ONU数据， 即OLT不必依次向各个ONU发送采集请求，而更改为只向目标ONU发送采集请求。
作为一个示例，OLT可以同时与多个ONU建立连接，若需要采集某个ONU的数据，可以向该ONU发送采集请求。
其中，ONU的数据可以包括：ONU名称、下行FEC(Forward Error Correction，前向纠错码)校正字节数、下行接收code words(代码字)总数、下行FEC校正时间、ONU接收到GEM(G-PON Encapsulation Mode，GPON封装方式)HEC(Header Error Checksum，头错误校验)数、丢弃的PON GEM帧数等。
S102：收集ONU数据并基于采集模型生成采集报文，采集报文的编码格式与上层采集平台可识别的编码格式相同。
ONU在接收到采集请求后，收集ONU数据并基于采集模型对ONU数据进行编码，得到采集报文。
其中，采集模型是一种对数据进行编码处理的数据处理模型，采集模型可以位于ONU内部。
在本申请的一个实施例中，采集模型是遥测采集模型，采集报文是遥测采集报文。
本申请的一个实施例中，采集模型定义采集报文的编码格式，即基于采集模型能够将采集数据转换为特定编码格式的报文，也可以理解为特定编码格式的报文。
具体的，相关技术中，ONU基于OMCI协议向OLT发送采集数据，OLT需要对OMCI格式的ONU数据进行解析，然后进行编码格式转换，也就是将OMCI格式的ONU数据转换为特定编码格式的数据，该特定编码格式是上层采集平台可识别的编码格式。完成编码格式转换后，再发送至上层采集平台。
而本申请实施例中，采集模型定义报文的编码格式，所定义的编码格式可 以与上层采集平台可识别的编码格式相同，从而，ONU基于采集模型定义的编码格式将ONU数据转换为采集报文，该采集报文能够直接被上层采集平台识别，因此，OLT不再需要进行解析和格式转换。
S103：通过OLT与ONU之间的网络连接，将采集报文推送至OLT，以使OLT向上层采集平台转发采集报文。
由于ONU生成的采集报文能够直接被上层采集平台识别，因此OLT不再需要对报文进行解析和格式转换，直接向上层采集平台转发报文即可。
具体的，OLT内部包含OLT Telemetry协议栈，ONU可以将采集报文发送至OLT Telemetry协议栈，OLT Telemetry协议栈通过特定协议推送至上层采集平台。其中，特定协议包括且不限于UDP(User Datagram Protocol，用户数据报协议)等；上层采集平台可以是Telemetry采集平台。
应用本申请实施例提供的ONU数据的采集方法，光线路终端OLT向光网络单元ONU发送采集请求；ONU在接收到采集请求后，收集ONU数据并基于采集模型对所述ONU数据进行编码，生成采集报文，所述采集报文的编码格式与上层采集平台可识别的编码格式相同，通过所述OLT与所述ONU之间的网络连接，将所述采集报文推送至所述OLT，以使所述OLT向所述上层采集平台转发所述采集报文。
可见，OLT无需通过轮询请求的方式采集ONU数据，而是向指定的ONU发送单次采集请求，随后该ONU基于采集模型将ONU数据转换为采集报文，且采集报文的编码格式与上层采集平台可识别的编码格式相同，从而ONU生成的报文能够直接被上层采集平台识别，因此OLT不再需要对报文进行解析和格式转换，直接向上层采集平台转发报文即可，大幅降低了数据采集的时延，能够满足工业场景下秒级采集ONU数据的用户需求。
本申请的一个实施例中，采集模型为proto模型，编码格式为protobuf格式。
其中，protobuf(Google Protocol Buffers)是一种平台无关、语言无关、可 扩展的轻便高效的编码数据存储格式。
protobuf是二进制编码，具有易编码、数据包小的优势。相关技术中，通常上层采集平台相匹配的编码格式为protobuf格式，因此基于proto模型，对ONU数据进行编码，得到的报文能够直接被上层采集平台识别，OLT不再需要对报文进行解析和格式转换。
为了便于理解，下面结合附图进行说明。
参见图2，图2为相关技术中ONU数据采集方法的一种示意图，如图2所示，相关技术方案中，ONU 23内置有采集芯片231，用于采集ONU数据并基于OMCI协议格式进行编码，将OMCI报文上报OLT 22，OLT 22内置有OMCI命令下发和解析模块224，该模块需要解析OMCI报文。随后protobuf编码模块222需要基于proto模型将采集到的数据编码为Telemetry报文，发送至OLT Telemetry协议栈221，然后再通过UDP协议发送至Telemetry采集平台21。如图2所示，OLT22内置有OLT采集模块223，用于采集OLT的相关数据，采集的OLT数据同样需要protobuf编码模块222进行编码，生成Telemetry报文，导致整个数据采集过程耗时较多，现网基本在5分钟以上时间粒度。
参见图3，图3为本申请实施例提供的ONU数据采集方法的一种示意图，如图3所示，本申请实施例中，ONU 33内置有采集模型331，采集模型331为proto模型，该模型定义编码格式为protobuf格式，从而ONU 33可以基于采集模型331对ONU数据进行编码，生成protobuf格式的采集报文，发送至OLT Telemetry协议栈321，然后再通过UDP协议发送至Telemetry采集平台31。如图3所示，OLT 32内置有OLT采集模块323，用于采集OLT的相关数据，采集的OLT数据需要protobuf编码模块322进行编码，生成Telemetry报文，发送至OLT Telemetry协议栈321，然后再通过UDP协议发送至Telemetry采集平台31。由于上层采集平台可识别的编码格式为protobuf，因此针对ONU数据，无需在OLT内部进行解析和格式转换，大幅降低了数 据采集的时延，能够满足工业场景下秒级采集ONU数据的用户需求。
本申请的一个实施例中，采集模型为远端采集模型。具体的，在工业PON场景下，将ONU内部采集的信息定义为远端采集信息，而采集模型位于ONU内部，且采集ONU数据，因此本申请实施例中，采集模型是远端采集模型。
本申请的一个实施例中，采集请求携带数据上报周期，相应的，将报文推送至OLT的步骤，具体可以包括：根据数据上报周期，周期性获取更新后的报文，并推送至OLT。
具体的，OLT向指定的ONU发送采集请求，采集请求携带数据上报周期，例如该周期为2秒。那么在后续推送的过程中，ONU持续采集数据并进行编码处理，生成采集报文，以2秒为周期获取最新的采集报文，推送至OLT。
从而，OLT无需频繁发起采集请求，只需向指定的ONU下发依次采集请求，该ONU即可持续采集数据并以秒级持续向OLT推送，利用ONU持续推送数据的模式来取代现有方案基于OMCI进行轮询请求的模式，进一步减少了相互交互的报文，实现秒级粒度高效采集ONU性能数据，且减轻设备压力。
本申请的一个实施例中，ONU数据可以包括ONU基础数据和/或预先自定义的ONU扩展数据。
具体的，现有技术中，基于OMCI协议采集ONU数据，但标准OMCI定义的数据内容较少，难以满足工业场景下用户对网络监控的需求。
由于本申请实施例中，不再基于OMCI协议采集ONU数据，因此为了满足工业场景下用户对网络监控的需求，可以预先自定义ONU扩展数据，这些ONU扩展数据可以采用proto模型进行编码，即proto模型支持将自定义的ONU扩展数据编码为报文。
如上文所述，ONU基础数据可以包括：ONU名称、下行FEC校正字节数、下行接收code words总数、下行FEC校正时间、ONU接收到GEM HEC错误数、丢弃的PON GEM帧数等。
预先自定义的ONU的扩展数据可以包括：内存利用率、CPU利用率、CPU的温度、ONU PON口发送报文个数、ONU PON口接收报文错误个数等。
可见，本申请实施例中，由于不再基于OMCI协议采集ONU数据，而采用新的采集模型，因此可以额外自定义ONU扩展数据，采集模型支持将自定义的ONU扩展数据编码为报文，从而可以采集更多种类的ONU数据，满足工业场景下用户对网络监控的需求。
并且，不同厂商的ONU均可以采用统一的proto模型进行ONU数据采集、数据上报，因此采用本申请实施例提供的ONU数据的采集方法，能够实现异厂商ONU数据采集。也就是说，即使同一OLT下挂有不同厂商的ONU，不同厂商的ONU都内置proto采集模型，不同厂商的ONU均可以基于proto采集模型对ONU数据进行编码处理，并向同一OLT上报采集报文，因此不再受限于OMCI报文不支持异厂商的缺点，能够实现异厂商ONU数据的采集。

接收模块401，用于接收光线路终端OLT发送的采集请求；
