Description

一种光网络单元的管理方法、系统和相关设备
相关申请的交叉引用
本申请基于申请号为201910013162.1、申请日为2019年1月7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
本申请涉及无源光网络(PON，Passive Optical Network)技术领域，具体涉及一种光网络单元的管理方法、系统和相关设备。
背景技术
PON是以点到多点为特征的单纤双向无源光网络，包括三个组件：光线路终端(OLT，Optical Line Terminal)、光网络单元(ONU，Optical Network Unit)和光分配网络(ODN，Optical Distribution Network)。OLT实现光纤线路终端的功能，控制ONU的注册、认证、带宽分配并对ONU进行管理。ONU作为ODN的终端设备，根据ONU设备的类型和网络位置的不同，ONU设备具备不同的业务适配功能以及向用户提供不同种类和数量的用户网络接口(UNI，User Network Interface)。ODN定义了PON中上下行传输方向以及使用的波长。
光网络单元管理控制接口(OMCI，ONU Management and Control Interface)协议是OLT与ONU之间的管理协议，OLT通过OMCI数据交互实现对ONU的管理控制。OMCI协议允许OLT执行ONU连接建立与释放、UNI接口管理、性能统计以及事件自上报等动作，提供了配置管理、故障管理、性能管理以及安全管理四个方面的主要管理功能。
目前的PON体系中，ONU设备由各厂家独立制造，由于各厂家技术差异导致ONU设备和OLT之间存在互通性问题，主要包括：1，各厂家在ONU设备生产过程中，为方便管理定义大量私有OMCI管理实体(ME，Managed Entities)，私有ME的存在导致ONU设备难以实现统一管控，OLT无法管理不同厂家的ONU设备；2，各厂家对于ME参数的理解不同造成ONU设备的差异化，导致难以实现统一的管控方案；3，OMCI 协议通过对ONU设备中的ME相互组合和关联实现L2层、L3层及以上不同功能，由于不同厂家ONU设备的差异性导致各厂家ONU设备ME组合和关联的方式不同，OLT需要适配各种ME组合和关联方式，增加了管控的复杂性。

具体实施方式
下面结合附图及具体实施例对本申请作进一步详细的说明。
本申请实施例提供了一种ONU的管理方法。图1为本申请实施例的ONU的管理方法的流程示意图一；如图1所示，所述方法包括：
步骤101：确定ONU上线后，生成第一指令和第二指令；所述第二指令携带表征所述ONU身份的第一指定标识。
步骤102：通过第一接口发送所述第一指令至OLT，所述第一指令用于所述OLT进行参数配置。
步骤103：根据所述第二指令生成第一管理报文，通过第二接口发送所述第一管理报文至所述ONU；所述第一管理报文通过所述OLT发送至所述ONU；所述第一管理报文携带所述第一指定标识。
本实施例的ONU的管理方法应用于ONU的管理设备中，ONU的管理设备也可称为虚拟设备层。ONU的管理设备用于对不同的ONU实现统一管理。作为一种实施方式，ONU的管理设备可由至少一个逻辑单元组成。实际应用中，ONU的管理设备可以由独 立的服务器实现，或者也可以由已有的服务器中的独立逻辑模块实现。
本实施例中，ONU的管理设备至少具有第一接口和第二接口；第一接口用于对OLT进行管理，主要包括OLT参数配置、建立与ONU之间的OMCI通道等等；第二接口用于管理ONU设备，主要涉及ONU设备各类ME的配置、查询、告警设置等等。
在本申请的一种可选实施例中，所述确定ONU上线，包括：通过所述第一接口获得所述OLT发送的ONU上线消息；所述ONU上线消息包括OLT标识、ONU标识和ONU定位信息；基于所述ONU上线消息确定ONU上线。
其中，OLT标识用于表示OLT设备，作为一种示例，OLT标识可通过OLT的IP地址表示；ONU标识用于表示OLT设备，ONU标识可通过序列号(SN，Series Number)、密码(Password)和媒体访问控制(MAC，Media Access Control)地址等参数表示；ONU定位信息用于建立与ONU设备之间的通道，ONU定位信息可通过板卡信息、端口信息和ONU号等信息表示。
本实施例中，OLT设备在发现ONU设备上线后，通过第一接口向ONU的管理设备上报ONU上线消息；ONU的管理设备对ONU上线消息进行解析，获得ONU上线消息中携带的OLT标识、ONU标识和ONU定位信息。实际应用中，OLT设备可基于物理层OAM(PLOAM，Physical Layer OAM)消息、嵌入操作维护管理(OAM，Operation Administration and Maintenance)等PON层消息发现ONU设备上线。
在本申请的一种可选实施例中，所述方法还包括：根据所述OLT标识、所述ONU标识和所述ONU定位信息生成第一指定标识。
本实施例中，所述第一指定标识为针对一ONU的特定标识，一方面，所述第一指定标识对应于唯一的ONU，另一方面，所述第一指定标识还对应于与该ONU连接的OLT；不同的ONU设备对应不同的指定标识(这里指第一指定标识)；ONU的管理设备根据OLT标识、ONU标识和ONU定位信息生成对应于该ONU的唯一指定标识，使得OLT和ONU的管理设备能够识别和解析。
作为一种示例，ONUm与OLTx之间通过OLT板卡b的端口s建立数据通道，ONU的管理设备得知发往ONUm的报文需经过OLTx板卡b的端口s时，将OLT标识x、板卡b、端口s以及ONU标识m进行线性组合得到标识z＝xbsm，标识z＝xbsm作为ONUm的第一指定标识。其中，m可以包括该ONU的SN、Password、MAC地址(或IP地址)等信息。
在本申请的一种可选实施例中，所述生成第一指令和第二指令，包括：根据所述 ONU上线消息生成第一指令和第二指令；其中，所述第二指令携带所述第一指定标识。
本实施例中，ONU的管理设备获得ONU上线消息后，为完成ONU上线，根据ONU设备上线需要执行的动作和操作参数，将后续操作指令分别映射为针对OLT的第一指令和针对ONU设备的第二指令，其中，所述第二指令携带有所述第一指定标识。
本实施例中，所述第一指令中携带OLT进行参数配置的相关参数，所述参数包括接口配置参数，用于建立与ONU设备之间的通信通道(OMCI通道)，为管理ONU设备提供接口。
在本申请的一种可选实施例中，所述根据所述第二指令生成第一管理报文，包括：获得所述第二指令对应的针对所述第一指定标识的至少一个第一管理报文；基于所述第二接口的协议封装所述至少一个第一管理报文，所述至少一个第一管理报文携带所述第一指定标识。
本实施例中，所述第二指令携带有所述第一指定标识，用于实现对指定的OLT的指定ONU设备进行管理。其中，ONU的管理设备中可预先针对不同的指令配置对应的管理报文。可以理解，在获得第二指令后，获得所述第二指令对应的至少一个第一管理报文。所述至少一个第一管理报文通过第二接口发送，主要用于ONU设备中的各类ME配置、查询、告警设置等。
例如：根据ONU已上线指令，生成同步码获取、管理信息库(MIB，Management Information Base)数据重置、更新、下发ONU配置等一系列管理报文。又例如，根据软件升级指令，生成软件下载、软件激活和软件确认等一系列管理报文。
本实施例中，所述管理报文(这里为第一管理报文)包括基本格式和扩展格式；其中，
对于基本格式，管理报文采用固定48字节，其中消息内容为32字节，包头包含4个字段事物相关标识、消息类型、基本类型/扩展类型选项、实体标识(ID)，包尾添加循环冗余校验(CRC，Cyclic Redundancy Check)信息。
对于扩展格式，管理报文采用最大1980字节，其中消息内容最大为1966字节，包头包含五个字段事物相关标识、消息类型、基本类型/扩展类型选项、实体ID、消息长度，包尾添加CRC信息。
其中，所述消息类型包括三个字段，包括是否需要回应标志、是否为回应报文和消息类型，其中消息类型包括create类型、delete类型、set类型或get类型等。
本实施例中，所述基于所述第二接口的协议封装所述至少一个第一管理报文，表示 将生成的所述至少一个第一管理报文按照适合于第二接口的协议进行封装，并在封装好的报文中添加所述第一指定标识。
本实施例中，所述第一接口和第二接口是基于不同协议规范的不同接口。例如，第一接口使用简单网络管理协议(SNMP，Simple Network Management Protocol)，遵循SNMP已有的参数和管理接口，实现对OLT的管理，以减少对OLT的改造；第二接口使用标准化的谷歌远程过程调用(GRPC，Google Remote Procedure Call)协议，实现对不同ONU的统一管理，以解决互通问题。
在本申请的一种可选实施例中，所述方法还包括：获得所述第一指令对应的第一执行结果，以及获得所述第一管理报文对应的第二执行结果；其中，所述第一执行结果来自所述OLT，表明所述OLT执行参数配置后的执行结果；所述第二执行结果来自所述ONU，所述第二执行结果由所述ONU发送，经所述OLT到达ONU的管理设备；所述第二执行结果表明所述ONU对所述第一管理报文的执行结果。
本实施例中，ONU的管理设备下发第一指令和第一管理报文后，需要OLT以及ONU反馈响应消息(即反馈执行结果)，确保指令正确执行。
其中，所述第一执行结果在OLT完成本地参数配置以及与ONU的OMCI通道建立完成后、经第一接口上报到ONU的管理设备。
其中，所述第二执行结果在第一管理报文经OLT发送到ONU后，ONU解析并发送响应信息至OLT，OLT检测到响应信息后，经第二接口发送第二执行结果至ONU的管理设备。
在本申请的一种可选实施例中，所述方法还包括：获得ONU操作指令，所述ONU操作指令携带第二指定标识；根据所述ONU操作指令生成携带有所述第二指定标识的第三指令；根据所述第三指令生成第二管理报文，通过所述第二接口发送所述第二管理报文至所述第二指定标识对应的ONU；所述第二管理报文通过所述OLT发送至所述第二指定标识对应的ONU；所述第二管理报文携带所述第二指定标识。
本实施例中，所述ONU操作指令来自管控设备；管控设备可通过标准接口将ONU操作指令发送到ONU的管理设备，ONU的管理设备对ONU操作指令进行解析。例如：EMS网管设备可以基于SNMP协议与ONU的管理设备通信，SDN控制器可以基于Netconf/Yang协议与ONU的管理设备通信。其中，所述ONU操作指令至少包括：OLT标识、ONU标识等标识信息，所述ONU操作指令还可包括动作以及对应的操作参数；其中，所述动作包括配置动作和/或查询动作；所述操作参数包括连接状态操作参数和/ 或接口名称操作参数等等。
其中，所述ONU的管理设备接收到来自管控设备的ONU操作指令后，通过ONU操作指令携带的动作和操作参数，将ONU操作指令映射为对ONU设备的指令，映射后的指令仍包含所述第二指定标识。
这里，所述ONU操作指令可用于指示业务的配置参数的配置、设备运行状态的查询等。所述ONU操作指令中携带有对应于一ONU的第二指定标识。所述第二指定标识与前述第一指定标识的含义相同，这里不再赘述。
本实施例中，ONU的管理设备接收到ONU操作指令后，根据所述ONU操作指令生成第二管理报文。作为一种示例，ONU的管理设备中可预先针对不同的指令配置对应的管理报文。可以理解，在获得ONU操作指令后，获得所述ONU操作指令对应的第二管理报文。
