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， 所描述的实施例仅仅是本发明一部分实施例， 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。
基于现有技术中网元内部光纤连接全集的配置由人工配置完成而存在 的人工配置数据量大、 易出错、 维护费用高等问题， 本发明提供了一种网 元内部光纤连接自动发现的方法、 装置和系统。 所述方法可以自动发现实 际的物理光纤连接， 将所有连接数据上 · ^给 ASON, ASON对其进行识别 后， 生成内部路由计算的全集， 从而解决了人工配置容易出错、 工作量大 的问题， 为 SPC业务向 SC业务过渡， 实现了使 SC业务完全不依赖于网管 的最后一个条件。
具体的， 本发明提供的一种网元内部光纤连接自动发现的方法， 如图 1 所示， 具体包括以下步骤： 步骤 S 101、 宿单板根据预设周期内接收到的源单板发送的三元组消息 判断与源单板是否为首次连接， 若是， 将结合自身三元组消息生成的六元 组消息发送至自动交换光网络 ASON, 并保存该六元组消息到本地数据库； 否则， 在定时时间到达时， 将本地数据库中存储的与接收到的三元组消息 对应的六元组消息发送至 ASON。
其中， 源单板发送的三元组消息包括源单板类型、 源单板地址和发光 口的端口号信息； 宿单板自身的三元组消息包括宿单板类型、 宿单板地址 和收光口的端口号信息。
具体的， 该步骤还进行以下操作：
当宿单板在预设周期内未收到源单板发送的任何消息且与源单板为非 首次连接时， 将本地数据库中存储的与源单板三元组消息对应的六元组消 息发送至 ASON, 并将该六元组消息在本地数据库中删除。
当所述宿单板在预设周期内接收到的源单板发送的消息不是三元組消 息时， 将该消息丟弃。
步骤 S 102、 ASON接收六元组消息， 并判定本地未存储该六元组消息 时， 检测六元组消息对应连接的合法性， 在对应连接合法时， 在本地存储 该六元组消息， 否则， 向用户显示连接错误信息。
进一步的， 当 ASON判定本地存储有接收到的六元组消息时， 判断本 次接收六元组消息的时间与本地存储六元组消息的时间差是否为上述定时 时间间隔的整数倍， 若是， 继续接收六元组消息， 否则， 将该六元组消息 在本地删除。
需要说明的是， 该步骤中具体将六元组消息存储在本地 ASON网元内 部路由数据链表中。
本发明提供的方法在 ASON内部自动生成该波分智能网元的内部光纤 连接路由链表， 避免了人工在网管上下发配置的重复烦瑣的工作， 而且在 单板自动发现、 链路自动发现、 邻居自动发现已经实现的基础上， 该方案 实现的内部光纤连接自动发现， 解决了 SC连接的最后一个瓶颈。
下面通过一较佳实施例来详细阐述本发明的具体实现过程。
本发明实施例是对波分 ASON 网元各个单板和 ASON 的功能进行扩 展， 具体工作原理为： 宿单板根据预设周期内接收到的源单板发送的三元 组消息判断宿单板与源单板是否为首次连接， 若是， 将结合自身三元组消 息生成的六元组消息发送至自动交换光网络 ASON， 并保存六元组消息到 本地数据库； 否则， 在定时时间到达时， 将本地数据库中存储的与三元组 消息对应的六元组消息发送至 ASON; ASON接收六元组消息， 并判定本 地未存储该六元组消息时， 检测六元组消息对应连接的合法性， 在该连接 合法时， 在本地存储该六元组消息， 否则， 向用户显示连接错误信息， 其 具体的数据流向如图 2所示。
具体的， 本发明实施例提供的实现波分 ASON网元内部光纤连接自动 发现的方法在单板侧的具体实施过程， 如图 3所示， 包括以下步骤：
步骤 S301、 消息发送源单板周期性的向消息接收宿单板发送自身的三 元组消息。 其中， 三元组消息包括源单板的类型、 源单板地址和源单板发 光口的端口号信息。
需要说明的是， 该步骤中涉及到的周期可以根据具体要求设定， 在此 并不对其值做具体限定。
步骤 S302、 宿单板实时监听在预设周期内是否接收到源单板发送的消 息， 若是， 执行步骤 S303 , 否则执行步骤 S307。
其中， 该步骤中的预设周期与步骤 S301中的周期相同， 但是在考虑到 系统延迟等因素， 本步骤中的周期可略长于步骤 S301中的周期。
步驟 S303、对接收到的消息进行解析， 判断该消息是否为三元组消息， 若是， 执行步骤 S304, 否则， 将该消息丢弃后执行步骤 S302。 步骤 S304、 将接收到的三元组消息与本地数据库中存储信息的前三项 作对比来确认是否是一条已经存在的连接， 若是， 执行步骤 S305; 否则执 行步骤 S306。
步骤 S305、 在设定的定时时间到达时， 将本地数据库中存储的与三元 组消息相对应的六元组消息发送到 ASON。
其中， 定时时间为在首次接收三元组消息后， 以特定时间段为周期的 间段时间信息， 例如， 在首次接收三元组消息后， 宿单板在后续的连续周 期内均收到源单板发送的三元组消息时， 并不会立即将存储的与三元组消 息对应的六元组消息发送给 ASON, 而是， 在首次接收后， 在特定时间段 (例如 20min ) 到达时刻， 向 ASON发送本地存储的六元组消息。 当然， 在 20min时发送六元组消息后，再隔 20min后再向 ASON发送六元组消息， 依此类推， 即首次连接建立起来后， 若源单板与宿单板间的连接状态良好， 宿单板会每隔 20min向 ASON发送一次源单板和宿单板对应的六元组消息。 该六元组消息的发送用来通知 ASON， 源单板与宿单板之间的连接良好。
步骤 S306、 根据接收到的三元组消息与宿单板自身的三元组消息， 组 合成六元组消息， 并将此六元组消息发送至 ASON, 同时将该六元组消息 存储至本地数据库中， 然后返回步骤 S302。
其中， 宿单板自身的三元组消息包括宿单板类型、 宿单板地址与宿单 板收光口端口号信息。
步骤 S307、判断宿单板与源单板是否为首次连接，若是,返回步骤 S302 , 否则执行步骤 S308。
其中， 首次连接理解为： 源单板与宿单板之前未连接过， 本次为二者 的首次连接； 或者源单板与宿单板之前连接过， 但是由于某种原因二者间 的连接中断了而进行的再次连接。
步骤 S308、 将本地数据库中存储的与该源单板三元组消息对应的六元 组消息发送至 ASON , 以告知 ASON该六元组消息对应的连接已不存在， 同时将本地存储的对应六元组消息删除。
需要说明的是， 宿单板向 ASON发送的消息是按照单板与 ASON间的 标准通讯格式发送的， 在此并不存在技术问题。
下面详细阐述本发明实施例提供的实现波分 ASON网元内部光纤连接 自动发现的方法在 ASON侧的具体实施过程， 如图 4所示， 具体包括以下 步骤：
步骤 S401、 ASON接收并解析出宿单板发送的六元组消息。
步骤 S402、 判断该六元组消息是否存在于本地 ASON网元内部路由数 据链表中， 若存在， 执行步骤 S403; 否则， 执行步骤 S405。
步骤 S403、 判断本次接收的六元组消息的时间与本地 ASON网元内部 路由数据链表存储六元组消息的时间差是否为定时时间间隔的整数倍， 若 是， 返回步骤 S401 ; 否则， 执行步骤 S404。
步骤 S404、 判定该六元组消息对应的连接已经不存在， 将该六元组消 息在本地 ASON 网元内部路由数据链表中删除， 并告知用户， 返回步骤 S401。
步骤 S405、 根据预先生成的光纤连接识别规则， 对本次接收的六元组 消息进行识别， 判断该六元组消息对应的连接是否为一条正确的连接， 若 是， 执行步骤 S406; 否则， 执行步骤 S407。
其中， 光纤连接识别规则为 ASON通过内部的 ASON单板自动发现模 块发现的网元内单板消息和预知经验知识生成的。 该识别准则即为单板地 址、 单板类型与端口号的匹配准则。
步骤 S406、 告知用户该连接正确， 并将该连接添加到本地 ASON网元 内部路由数据链表中， 返回步骤 S401。
步骤 S407、 显示该连接错误， 提醒用户检查实际物理光纤连接， 返回 步骤 S401。
其中， 连接错误举例表述为： 若源端口是发端口， 宿端口也是发端口， 则是错误连接； 若源单板 OTU, 宿单板是 WSU/D, 则也是错误连接， 等等。
为了更清楚的阐述本发明的技术方案， 下面通过一个波分 ASON网元 内部光纤连接的实例来进一步说明本发明所提供方法的实现过程。
本发明实例把波分智能网元内部的所有光纤连接都发现出来， 然后通 过单板与 ASON通讯通道， 上报给 ASON， ASON对该结果进行识别。 如 图 5 所示， 为本实例中网元内部光纤连接示意图， 一条光纤连接的实例如 图中的虚线所示， 表征光纤由 0-2-16地址（2子架 16槽位 ) 的 PDU单板 的 1-2端口连接至 0-1-18地址 （ 1子架 18槽位） 的 WSU单板的 A3端口。 在具体实现过程中， 可在图中虚线所示的主光通道上， 载入一个新的波长， 作为承载发端口发送的源单板三元组消息的物理通道。 而网元内部单板与 ASO 通讯通道如图所示， 该通道上的数据不再经过 SNP主控板。
具体的网元内部光纤连接自动发现的过程如下：
依照图 5中所示的 0-2-16地址 （2子架 16槽位） 的 PDU单板为例， PDU的 （1-2 )端口把自身单板类型 （PDU )、 单板地址（0-2-16 )与发光口 的端口号 （ 1-2 ) 这个三元组消息按照定时的方式， 调制到载波波长上， 发 送到宿单板 WSU ( 0-1-18 )。
WSU的 A3端口监听对端发来的消息， 如收到消息后， 对消息进行解 析， 若该消息为三元组消息且为首次接收， 则将之与本板的单板类型 ( WSU )、 单板地址（0-1-18 ) 与收光口端口号 （ A3 )组合成六元组消息， 将此六元组消息发送至与 ASON; 若该消息不是三元组消息， 则将该消息 丟弃。
ASON接收 WSU单板发来的消息， 将其中的六元组消息解析出来， 并 根据光纤连接识别规则 （PDU可以连接至 WSU )对该六元组进行分析， 确 认这是一条正确的光纤连接。 在 ASON 内通过命令行等方式向用户显示此 条连接的正确性， 并同时将此条连接加入到 ASON网元内部路由数据链表 中。
发明还提供一种单板， 如图 6所示， 包括： 消息接收模块 610和通讯 模块 620, 其中，
消息接收模块 610,用于根据预设周期内接收到的源单板发送的三元组 消息判断与源单板是否为首次连接， 若是， 将结合自身三元组消息生成的 六元组消息发送至通讯模块 620,并保存该六元组消息到本地数据库；否则， 在定时时间到达时， 将本地数据库中存储的与接收到的三元组消息对应的 六元组消息发送至通讯模块 620;；
通讯模块 620, 用于接收消息接收模块 610发送的六元组消息， 并将该 六元组消息转发至 ASON。

单板 710, 包括： 消息接收模块 711 ,用于根据预设周期内接收到的源单板发送的三元组 消息判断与源单板是否为首次连接， 若是， 将结合自身三元组消息生成的 六元组消息发送至通讯模块 712,并保存该六元组消息到本地数据库；否则， 在定时时间到达时， 将本地数据库中存储的与接收到的三元组消息对应的 六元组消息发送至通讯模块 712;；
通讯模块 712, 用于接收消息接收模块 711发送的六元组消息， 并将该 六元组消息转发至 ASON 720。
ASON 720, 包括：
六元组消息接收模块 721 , 用于接收单板 710发送的六元组消息； ASON光纤连接识别模块 722 ,用于判定本地未存储六元组消息接收模 块 721 接收的六元组消息时， 检测该六元组消息对应连接的合法性， 在对 应连接合法时， 在本地存储该六元组消息， 否则向用户显示连接错误信息。
进一步的， 本发明提供的系统中， 单板 710还包括： 消息定时发送模 块 713， 用于周期性的向消息接收宿单板发送所在单板的三元组消息； ASON光纤连接识别模块 722,还用于当判定本地存储有六元组消息接 收模块 721 接收的六元组消息时， 判断本次接收六元组消息的时间与本地 存储六元组消息的时间差是否为定时时间间隔的整数倍， 若是， 触发六元 组消息接收模块 721， 否则， 将该六元组消息在本地删除。
显然， 本领域的技术人员可以对本发明进行各种改动和变型而不脱离 本发明的精神和范围。 这样， 倘若本发明的这些修改和变型属于本发明权 利要求及其等同技术的范围之内， 则本发明也意图包含这些改动和变型在 内。
