Description

一种 ONU管理维护方式的选择方法和系统 技术领域
本发明涉及网络通信中的互通性技术, 尤其涉及一种光网络单元 ( ONU )管理维护方式的选择方法和系统。 背景技术
现有的以太网无源光网络 ( EPON , Ethernet Passive Optical Network ) 系统如图 1所示, 光线路终端(OLT, Optical Line Terminal )通过分光器连 接光网络单元( ONU , Optical Network Unit ), 且 OLT和 ONU都由网络管 理系统(NMS, Network Management System )服务器进行管理。 对于 ONU 的管理维护大多釆用简单网络管理协议 ( SNMP , Simple Network Management Protocol ) +扩展操作维护管理 (eOAM , extended Operation Administration and Maintenance ) 的方式; 同时也存在另外一种方式, 即釆 用 SNMP+ONU管理控制通道接口 (OMCI, ONU Management and Control Interface ) 的方式。 SNMP接口负责 NMS和整个 EPON系统对端口、 协议 和业务的相关功能的管理维护; 而 eOAM/OMCI负责 EPON系统中 OLT和 ONU之间的 PON协议相关功能的维护管理。
对于支持多种管理维护方式的 EPON系统,需要针对不同的应用场景, 在 OLT和 ONU之间选择一种适当的管理方式, 对 ONU进行管理维护。 例 如: OLT同时支持 eOAM和 OMCI两种管理方式, ONU或者支持 eOAM, 或者支持 OMCI; OLT和 ONU同时既支持 eOAM, 也支持 OMCI。 在特定 的应用场景下, 如果不确定如何选择 ONU的管理维护方式, 将会影响不同 厂家的 EPON相关设备的互通性。 发明内容
有鉴于此,本发明的主要目的在于提供一种 ONU管理维护方式的选择 方法和系统, 以实现 ONU管理维护方式的自适应选择。
为达到上述目的, 本发明的技术方案是这样实现的:
本发明提供了一种光网络单元(ONU ) 管理维护方式的选择方法, 该 方法包括:
ONU将自身支持的管理维护方式上报给光线路终端 ( OLT );
所述 OLT从 ONU上报的管理维护方式中选择一种作为对所述 ONU的 该方法进一步包括: 当所述 ONU上报的管理维护方式为一种时, 所述 该方法进一步包括: 当所述 ONU上报的管理维护方式为多种时, 所述 OLT根据预先配置的策略从多种管理维护方式中选择一种作为对所述 ONU 所述预先配置的策略为: 随机选择管理维护方式、 或优先选择最常用 的管理维护方式。
所述 ONU 的管理维护方式包括以下至少一种: 扩展操作维护管理 ( eOAM )、 ONU管理控制通道接口 ( OMCI );
其中 , 所述 eOAM包括至少一种。
本发明还提供了一种 ONU 管理维护方式的选择系统, 该系统包括: ONU和 OLT, 其中,
所述 ONU, 用于将自身支持的管理维护方式上报给所述 OLT;
所述 OLT, 用于从 ONU上报的管理维护方式中选择一种作为对所述 ONU的管理维护方式, 并根据所选的管理维护方式对所述 ONU进行配置 管理。 所述 OLT进一步用于, 在所述 ONU上报的管理维护方式为一种时, 所述 0LT进一步用于, 在所述 0NU上报的管理维护方式为多种时, 根据预先配置的策略从多种管理维护方式中选择一种作为对所述 ONU 的 所述 OLT进一步用于, 所述预先配置的策略为: 随机选择管理维护方 式、 或优先选择最常用的管理维护方式。
所述 ONU的管理维护方式包括以下至少一种: eOAM、 OMCI;
其中 , 所述 eOAM包括至少一种。
本发明所提供的一种 0NU 管理维护方式的选择方法和系统, 针对 EP0N系统在部署中, 因为存在对 ONU的管理维护方式的多种解决方案导 致的互通性问题, 通过 OLT支持多种管理维护方式, 对 ONU支持的管理 维护方式进行适应和协商的方式, 可以艮好的解决 OLT和 ONU之间的互 通性问题, 且在完成管理运维互通的同时还可以降低 ONU实现的复杂度。 附图说明
图 1为现有 EPON系统的架构示意图;
图 2为本发明一种 ONU管理维护方式的选择方法的流程图; 图 3为本发明实施例一中通过协商选择 ONU管理维护方式的流程图; 图 4为本发明实施例二中通过协商选择 ONU管理维护方式的流程图; 图 5为本发明实施例三中通过协商选择 ONU管理维护方式的流程图; 图 6为本发明实施例四中通过协商选择 ONU管理维护方式的流程图。 具体实施方式
下面结合附图和具体实施例对本发明的技术方案进一步详细阐述。 针对 EPON系统中由于多种管理维护方式的存在, 对 EPON系统互通 性可能造成的影响, 本发明提出了一种 ONU管理维护方式的选择方法, 通 过统一的针对多种管理维护方式的自适应选择,来确定针对 ONU的管理维 护方式, 从而使得不同厂家的 EPON设备可以实现互通。 本发明的方法如 图 2所示, 主要包括以下步骤:
步骤 201 , ONU将自身支持的管理维护方式上报给 OLT。
为实现发明目的, 同时遵守 ONU尽量简单的原则, 本发明要求 OLT 同时支持各种管理维护方式, 包括但不仅限于 eOAM、 OMCI等等; 其中, eOAM包括至少一种, 如: eOAM管理维护方式 1、 eOAM管理维护方式 2 等等。 如果 ONU仅支持 eOAM这一种管理维护方式, 则将 eOAM管理维 护方式上报给 OLT; 如果 ONU仅支持 OMCI这一种管理维护方式, 则将 OMCI管理维护方式上 ^艮给 OLT; 如果 ONU同时支持 eOAM和 OMCI这 两种管理维护方式, 则将 eOAM管理维护方式和 OMCI管理维护方式上才艮 给 OLT。 另夕卜, 当 ONU所支持的 eOAM管理维护方式包括多种时, ONU 需要将自身支持的各种 eOAM管理方式都上报给 OLT。也就是说, ONU需 要将自身支持的所有管理维护方式都上报给 OLT, 以供 OLT进行选择。
步骤 202, OLT从 ONU上报的管理维护方式中选择一种作为对该 ONU 的管理维护方式, 并根据所选的管理维护方式对 ONU进行配置管理。
如果 ONU上^艮的管理维护方式仅为 eOAM管理维护方式, 则 OLT直 接将 eOAM管理维护方式作为对该 ONU的管理维护方式, 并釆用 eOAM 的消息格式对 ONU进行配置管理; 如果 ONU 上报的管理维护方式仅为 OMCI管理维护方式, 则 OLT直接将 OMCI管理维护方式作为对该 ONU 的管理维护方式, 并釆用 OMCI的消息格式对 ONU进行配置管理。
如果 ONU上报的管理维护方式为多种, 例如: 同时支持 eOAM管理 维护方式和 OMCI管理维护方式, 则 OLT需要 居预先配置的策略从多种 管理维护方式中选择一种作为对 ONU的管理维护方式,并根据所选的管理 维护方式对 ONU进行配置管理。该预先配置的策略包括但不限于随机选择 管理维护方式、 优先选择最常用的管理维护方式等等。 所谓随机选择管理 维护方式, 即从 ONU上 ^艮的管理维护方式中任选一种作为对 ONU的管理 维护方式; 所谓优先选择最常用的管理维护方式, 即从 ONU上报的管理维 护方式中选择最常用的作为对 ONU的管理维护方式,如果最常用的管理维 护方式为 eOAM管理维护方式, 则选择 eOAM管理维护方式, 如果最常用 的管理维护方式为 OMCI管理维护方式, 则选择 OMCI管理维护方式。
较佳的, OLT在选择完对 ONU的管理维护方式后, 可以将选择的结果 通知给 ONU。 另夕卜, 在上述步骤 201之前, OLT和 ONU之间还需要执行 多点控制协议( MPCP, Multipoint Control Protocol )的发现过程和 OAM的 发现过程。
由此可见, 通过本发明的上述方法, 要求 OLT侧支持多种管理维护方 式, 继而 OLT能够根据 ONU上报的管理维护方式(为 ONU自身当前支持 的管理维护方式), 自适应协商出最终支持的针对 ONU的管理维护方式, 从而可以使不同厂家的 OLT和 ONU在互通时, 在管理维护方式的选择上 不会出现问题, 从而在管理维护方面顺利的解决 OLT和 ONU互通性的问 题。
下面结合具体实施例对上述 ONU 管理维护方式的选择方法进一步详 细阐述。
在本发明的实施例一中, ONU仅支持 eOAM管理维护方式, 相应的管 理维护方式协商过程如图 3所示, 主要包括以下步骤:

步骤 302, OLT和 ONU之间完成 IEEE802.3ah或者 IEEE802.3av中定 义的 OAM发现过程。
步骤 303 , OLT向 ONU发送管理维护方式请求, 请求获取 ONU支持 的管理维护方式。
步骤 304, ONU将自身支持的管理维护方式上报给 OLT。 在本实施例 中, ONU通知 OLT其当前仅支持 eOAM管理维护方式。 协商, 并确定对 ONU的管理维护方式为 eOAM。 OLT向 ONU返回管理维 护方式确认消息, 将 OLT选择的结果告知 ONU。 后续 OLT将釆用 eOAM 的消息格式对 ONU进行配置管理。
在本发明的实施例二中, ONU仅支持 OMCI管理维护方式, 相应的管 理维护方式协商过程如图 4所示, 主要包括以下步骤:
步骤 401 , OLT和 ONU之间完成 IEEE802.3ah或者 IEEE802.3av中定 义的 MPCP发现过程。
步骤 402, OLT和 ONU之间完成 IEEE802.3ah或者 IEEE802.3av中定 义的 OAM发现过程。
步骤 403 , OLT向 ONU发送管理维护方式请求, 请求获取 ONU支持 的管理维护方式。
步骤 404, ONU将自身支持的管理维护方式上报给 OLT。 在本实施例 中, ONU通知 OLT其当前仅支持 OMCI管理维护方式。 协商, 并确定对 ONU的管理维护方式为 OMCI。 OLT向 ONU返回管理维 护方式确认消息, 将 OLT选择的结果告知 ONU。 后续 OLT将釆用 OMCI 的消息格式对 ONU进行配置管理。
在本发明的实施例三中, ONU同时支持 eOAM管理维护方式和 OMCI 管理维护方式, 相应的管理维护方式协商过程如图 5 所示, 主要包括以下 步骤:
步骤 501 , OLT和 ONU之间完成 IEEE802.3ah或者 IEEE802.3av中定 义的 MPCP发现过程。
步骤 502, OLT和 ONU之间完成 IEEE802.3ah或者 IEEE802.3av中定 义的 OAM发现过程。
步骤 503 , OLT向 ONU发送管理维护方式请求, 请求获取 ONU支持 的管理维护方式。
步骤 504, ONU将自身支持的管理维护方式上报给 OLT。 在本实施例 中, ONU通知 OLT其当前支持两种管理维护方式, 即 eOAM管理维护方 式和 OMCI管理维护方式。
步骤 505 , OLT根据 ONU上^艮的支持 eOAM管理维护方式和 OMCI 管理维护方式的信息进行协商, 并确定对 ONU的管理维护方式。
在本发明的实施例四中, ONU 同时支持 eOAM 管理维护方式 1 和 eOAM管理维护方式 2,相应的管理维护方式协商过程如图 6所示, 主要包 括以下步骤:
步骤 601 , OLT和 ONU之间完成 IEEE802.3ah或者 IEEE802.3av中定 义的 MPCP发现过程。
步骤 602, OLT和 ONU之间完成 IEEE802.3ah或者 IEEE802.3av中定 义的 OAM发现过程。
步骤 603 , OLT向 ONU发送管理维护方式请求, 请求获取 ONU支持 的管理维护方式。
步骤 604, ONU将自身支持的管理维护方式上报给 OLT。 在本实施例 中, ONU通知 OLT其当前支持两种管理维护方式, 即 eOAM管理维护方 式 1和 eOAM管理维护方式 2。
步骤 605 , OLT根据 ONU上报的支持的 eOAM管理维护方式 1和 eOAM 管理维护方式 2的信息进行协商, 并确定对 ONU的管理维护方式。
具体的, OLT根据预先配置的策略从多种管理维护方式中选择一种作 为对 ONU的管理维护方式。 以优先选择最常用的管理维护方式为例, 当前 已部署的 EPON系统中 ,针对 ONU的管理维护方式多为 eOAM管理方式 1 , 因此协商结果为: 针对 ONU的管理维护方式确定为 eOAM管理方式 1。 OLT向 ONU返回管理维护方式确认消息 , 将 OLT选择的结果告知 ONU。 后续 OLT将釆用 eOAM管理方式 1的消息格式对 ONU进行配置管理。
对应上述 ONU管理维护方式的选择方法, 本发明还提供了一种 ONU 管理维护方式的选择系统, 由 ONU和 OLT组成。 其中, ONU, 用于将自 身支持的管理维护方式上报给 OLT; OLT, 用于从 ONU上报的管理维护方 式中选择一种作为对 ONU的管理维护方式,并根据所选的管理维护方式对 ONU进行配置管理。
较佳的, 在 ONU上报的管理维护方式为一种时, OLT直接根据 ONU 上报的管理维护方式对 ONU进行配置管理; 在 ONU上报的管理维护方式 为多种时, OLT根据预先配置的策略从多种管理维护方式中选择一种作为 对 ONU的管理维护方式, 并根据所选的管理维护方式对 ONU进行配置管 理。
综上所述,针对 EPON系统在部署中, 因为存在对 ONU的管理维护方 式的多种解决方案导致的互通性问题, 本发明通过 OLT支持多种管理维护 方式, 对 ONU支持的管理维护方式进行适应和协商的方式, 可以艮好的解 决 OLT和 ONU之间的互通性问题, 且在完成管理运维互通的同时还可以 降低 ONU实现的复杂度。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围。
