和网管处理模块 46 , 即， 在实际的物理单板安装完毕以及光纤连接好之后， 每个单板内部的输入口监测模块 218和输出口监测模块 217都会监听上下游 单板所发送过来的"连接信息包"信息， 然后将此信息和本单板的连接信息一 起发送给单板连接信息模块 42; 单板连接信息模块 42将本单板现在的光纤 连接关系上报给网络管理装置 22 , 由网络管理装置 22根据实际安装单板的 信息所构成的网管实安板连接关系数据表对此连接关系做一判断， 对于正确 的连接关系， 网络管理装置 22上以图形或文本数据表的形式显示出来， 对 于错误连纤或少连纤的情况， 则给予一个建议性的连接关系。 如图 4所示， 下面对本优选实施例 1的各模块的功能做详细说明。
( 1 ) 单板信息模块 216 主要作用是存储单板自身的一些属性信息， 包括： 单板所属网元的节点 标识 ID, 单板地址信息， 单板类型信息， 光接口属性信息等。 其中， 单板所 属的网元的节点表识 ID, 主要用于标记单板所在网元的节点标识； 单板地址 信息， 即表示该单板的物理地址， 可以釆用常用的"机架号 +子架号 +槽位号，， 的编码方式； 单板类型信息， 即表示该单板的功能作用 （例如， 放大类单板、 业务类单板等）；光接口属性信息，表示单板所包含的一些光接口的属性信息， 包括光接口的数目信息、 光接口的方向信息、 光接口的序号信息、 光接口的 波长信息、 光接口的速率信息、 光接口的使用信息等。 具体地， 光接口属性 信息中各部分所表示的含义可以是： 光接口的数目信息， 表示单板的输入光 接口和输出光接口的数量； 光接口的方向信息， 表示所属的光接口是输入接 口还是输出接口， 如果是输入接口有光纤连接关系， 则在此光纤连接关系中 标识该单板为下游单板， 如果是输出接口有光纤连接关系， 则在此光纤连接 关系中标识该单板为上游单板； 光接口的序号信息， 表示每个光接口所对应 的编号序列； 光接口的波长信息， 表示该光接口所对应的波长通道信息； 光 接口的速率信息， 表示该光接口所对应的承载速率是多少； 光接口的使用信 息， 表示目前该单板的输入接口和输出接口有哪些已经有光纤连接， 还有哪 些端口剩余可用。 可见， 本模块将单板自身的一些属性信息， 分别发给单板输入口监测模 块 218和单板输出口监测模块 217, 由它们将这些信息封装成"连接信息包" 发给上游或下游的具有连接关系的单板， 同时也将这些信息发送给本单板的 单板连接信息模块 42 , 提供光纤连接关系中本端所需的相关信息。
( 2 ) 单板输出口监测模块 217 图 5是根据本发明优选实施例 1的单板输出口监测模块的流程图， 如图 5所示， 该模块执行以下处理： 步骤 S502,单板输出口监测模块 217使单板的所用输出光口定时（例如， 每隔 3秒） 向下游单板发送"连接信息包"信息， 其中， "连接信息包"所包含 的信息就是单板信息模块 216中所存储的信息。 单板输出口监测模块 217将 连接信息包信息调制到一个固定的载波上面， 然后通过主光通道 （实际的光 纤） 发送出去， 如果下游有实际的光纤连接， 则下游单板的输入口监测模块 218会将下游单板的一些属性信息和下游单板此时的输入口光口情况等封装 成下游单板的"连接信息包"形式， 发送回来。 步骤 S504, 接收到下游单板的返回来的 "连接信息包"， 然后将其解调并 解析出来。 步骤 S506, 将接收到下游单板的 "连接信息包 "同本单板的有关连接信息 包一起发给单板连接信息模块 42。 特殊地， 如果下游没有光纤连接或为断裂 的光纤， 则单板输出口监测模块 217监听到的响应信息为空， 然后单板输出 口监测模块 217也将此信息 （没有收到响应的 "连接信息包"） 会同本单板的 有关连接信息包一起发送给本单板的单板连接信息模块 42。 ( 3 ) 单板输入口监测模块 218 图 6是根据本发明优选实施例 1的单板输入口监测模块的流程图， 如图 6所示， 单板输入口监测模块 218使单板的所有输入光口定时 （例如， 每隔 3秒）监听、 接收和响应上游单板所发送的"连接信息包"。 该模块执行以下 处理： 步骤 S602, 单板输入口监测模块 218接收到了上游单板所发送的"连接 信息包"， 则将其解调下来。 步骤 S604, 给上游单板回应一个本单板的"连接信息包，，， 将此信息包调 制到一个固定的载波上面， 然后发送出去。 步骤 S606, 将上游单板的 "连接信息包 "和本地单板的有关连接信息包情 况一起发送给本单板的单板连接信息模块。 如果没有所有的输入光口都没有 收到"连接信息包，，， 则单板输入口监测模块 218也将此信息 （输入光口没有 收到任何"连接信息包"） 连同本单板的有关连接信息包一起发送给本单板的 单板连接信息模块。
( 4 ) 单板连接信息模块 42 图 7是根据本发明优选实施例 1的单板连接信息模块的流程图， 如图 7 所示， 该模块执行以下处理： 步骤 S702,接收单板输入口监测模块 218和单板输出口监测模块 217所 发送过来的 "连接信息包"信息。 步骤 S704,判断连接信息包中的信息是否是上次已经上报给网络管理装 置 22的有关信息。 如果是则单板连接信息模块对此信息不予考虑， 不上报 给网络管理装置 22。 步骤 S706,如果信息包中包含的信息与上次最新上 ·ί艮的信息包信息不一 致， 则说明有最新的光纤连接信息， 将此最新的光纤连接信息上报给网络管 理装置 22 , 更新网络管理装置 22上的光纤连接数据库和光纤连接显示信息。
( 5 ) 网管处理模块 46 图 8是才艮据本发明优选实施例 1的网管处理模块的流程图，如图 8所示， 网管处理模块 46是对单板连接信息模块 42上报上来的光纤连接信息进行判 断、 检验， 对于错连和少连的情况， 在还有其它上下游单板和端口的情况下 给予一个建议性的连接关系， 并将上述的所有结果在网络管理装置 22上都 给以相应的显示。 该模块执行以下处理： 步骤 S801 , 在网络管理装置 22数据库中存储有一张所有单板及其所有 光口的可能连纤关系数据表。 步骤 S802, 在网络管理装置 22上自动发现所有的实安板后， 才艮据目前 实际安装的单板类型及其所有光口， 网络管理装置 22生成一个新的包括所 有可能情况的实安板光纤连接关系数据表。 步骤 S803 , 网络管理装置 22收到单板连接信息模块 42上报的实际单板 最新的连纤关系。 步骤 S804, 判断单板输入口 /输出口是否都有光纤连接。 如果判断为是， 执行步骤 S805 , 否则， 执行步骤 S806。 步骤 S805 , 在实安板光纤连接数据表中查找此连接光纤， （即， 判断是 否存在单板或端口类型不匹配现象）。 当查找到有此光纤连接可能时（即， 判 断结果为否）， 网络管理装置 22就在实安板光纤连接数据表中将此条光纤连 接的对应单板和光口号故以标记 （表示该端口已经有正确的光纤连接信息）， 并将此正确的连接信息在网络管理装置 22的界面上以图形或数据表格的形 式显示出来。 当在实安板光纤连接数据表中未能找到有此光纤连接可能时 (即， 判断结果为是）， 说明此连接关系是错误的。 在确定此连接关系是错误的之后， 可以在实安板光纤连接数据表中再次 查找是否还有其他可用的建议性连接端口或单板。 如果没有， 则网络管理装 置 22将此错误的连接关系在网络管理装置 22的界面上以特殊的图形或数据 表格的形式显示出来（例如， 光纤连接的线条颜色为红色）； 如果有， 则网络 管理装置 22按照某种准则给出一条建议性的最优的光纤连接关系。 其中， 某种准则可以是： 按照单板类型相匹配， 光口类型相匹配的原则进行单板和 光口的选择， 即， 先进行上游单板输出光口的建议性匹配， 后进行下游单板 的输入光口的建议性匹配。对于可以匹配的单板按照最小距离原则进行匹配， 如果出现多块相同类型的可匹配单板， 按照"上面为上游单板， 下面为下游单 板； 左面为上游单板， 右面为下游单板； 左上为上游单板， 右下为下游单板； 右上为上游单板， 左下为下游单板，，的原则选择相应的可匹配单板。对于出现 多个可匹配端口的情况，按照光口号由小到大的顺序依次匹配即可；)。但不对 此光纤连接关系所对应的单板和有关光口在实安板光纤连接数据表中故标 记。 步骤 S806 , 当单板连接信息上报网络管理装置 22的连接信息包中出现 单板只有一端有光纤连接的情况时 （此情况有可能是实际上就是单板只有一 端有光纤连接， 而另一端没有光纤连接。 也有可能是单板的输入口和输出口 都有光纤连接， 但是有一端的光纤是断裂的）， 网络管理装置 22也会按照上 面所述的准则给没有光纤连接关系的一端一个建议性的最优的光纤连接关 系， 但不对此光纤连接关系所对应的单板和有关光口在实安板光纤连接数据 表中做标记。 对于某些业务板则还需进一步判断其是否是只用于上路或下路 的业务板。 当下面的单板连接信息上报网络管理装置 22的连接信息包中出现单板 两端都没有光纤连接关系的情况时 （此情况有可能是实际的单板两端确实没 有光纤连接情况， 也有可能是有光纤连接， 但光纤是断裂的情况）， 网管对于 这些单板不予考虑。 釆用本优选实施例的不但可以自动发现实际的光纤连接关系， 省去了人 工手动在网络管理装置 22上配置光纤连接的操作， 而且对于实际错连和单 板端口一端少连的情况， 也给予校验和警示的信息， 并给以建议性的光纤连 接关系， 特别是对于光纤断裂等实际不易察觉的情况， 提供了很好的发现和 定位功能。 优选实施例 2 本优选实施例 2应用于光网络内部， 在实际的物理光纤连接好以后， 可 以自动发现实际的光纤连接关系， 并且对于相关的内容给予提示。 下面对本 优选实施例 2的光纤连接的检测流程进行详细说明。 首先， 可以按照上下游单板就近安装的原则， 安装实际的单板和实际的 光纤连接。 网络管理装置 22 自动发现所有的实安板信息后， 和网络管理装 置 22上固有的一个所有单板的所有光口的可能连纤关系数据表取"交集"，生 成一个实安板光纤连接关系数据表。 然后， 由单板输入口监测模块 218和输出口监测模块 217分别监听和发 送对应的"连接信息包"信息。 其中， 单板输出口监测模块 217定时（或定期） 向下游单板发送有关本单板属性及当前单板光纤实际的连接情况的 "连接信 息包"信息，并且在接收到下游单板所响应的"连接信息包"后，将该响应的"连 接信息包"信息连同本单板的"连接信息包"一起发送给单板连接信息模块；单 板输入口监测模块 218定时（或定期）监听和接收上游单板所发送过来的 "连 接信息包"信息， 并回应一个有关本单板响应信息的"连接信息包"信息， 并且 也将上游单板的"连接信息包"信息连同本单板的"连接信息包"信息一起上报 给本单板的单板连接信息模块。 其次， 单板连接信息模块 42在接收到单板输入口监测模块 218和单板 输出口监测模块 217所发送过来的 "连接信息包"信息后， 判断"连接信息包" 中所示的单板光纤连接关系是否是上次已经上报给网络管理装置 22的最新 的光纤连接关系。 如果是， 则不上报给网络管理装置 22 (即， 单板连接信息 模块对此信息不予考虑）； 如果不是， 则将此最新的光纤连接关系上报给网络 管理装置 22。 再次， 当网管处理模块 46接收到单板连接信息模块 42上报上来的最新 连纤信息时， 就按照网络管理装置 22数据库中存储的所有单板及其所有光 口的可能连纤关系数据表对单板光纤连接的各种情况——进行判断， 对应正 确的光纤连接关系， 网管处理模块 46将其在网络管理装置 22界面上正常显 示出来， 并且将此连接信息所对应的单板和端口在实安板光纤连接关系数据 表中做相应的标记。 对于光纤进行错连或少连的情况， 网络管理装置 22界 面上给予特殊的显示， 并且在还有其它可用端口和单板的情况下， 给以一个 建议性的光纤连接关系。 釆用本优选实施例不但节省了大量的人力资源， 提高了系统的效率， 降 低了系统维护的成本， 而且也是智能交换光网络由软永久连接 （Soft
Permanent Connection, 简称为 SPC )业务向交换连接（ Swithched Connection, 简称为 SC ) 业务演进智能化的一个重要体现。 优选实施例 3 图 9是根据本发明优选实施例 3的波长交换光网络 （Wavelength
Switched Optical Network, 简称为 WSON)系统网元内部的光纤连接示意图， 如图 9所示， 釆用本优选实施例， 网络管理装置 22不但可以自动发现实际 的光纤连接关系， 而且对于错误的光纤连接关系和只有一端有光纤连接关系 的情况， 给予相应的提示信息， 并且给予一个建议性的连接关系。 例如， 在 图 9中放大单板 1的 OUT1口和功率分配单板 4的 IN2口之间的光纤连接关 系是正确的， 放大单板 2的 OUT1 口和功率分配单板 4的 OUT8口的光纤连 接关系是错误的， 波长选择单板 6的 OUT1 口和放大单板 3的 IN1 口没有光 纤连接关系。 下面对本优选实施例的处理过程详细进行说明。 在对单板进行规划和上下游单板按照就近原则进行安装完并且连好光纤 以后， 首先， 网络管理装置 22数据库中有一张所有单板及其光口的所有可 能连纤关系数据表， 在自动发现所有的实安板信息后， 根据目前实际安装的 单板类型及其所有光口， 网络管理装置 22生成一个新的实安板光纤连接关 系数据表。 同时， 每个单板中的单板信息模块会生成本单板的属性信息以及 现在单板的光口使用情况等， 即生成本单板所发送的"连接信息包"中的应有 信息。 例如， 0-1-10槽位上的放大单板 1中单板信息模块中的信息如下表， 其他单板与此类似。

光接口的使 IN1 口和 OUT1 口在使用 （检测到有光纤连接）， IN2 用情况 和 OUT2口没有在使用 然后， 单板中的单板输出口监测模块就将本单板的单板信息调制到某一 固定载波上，通过所有的输出光口发送出去，对于有光纤连接关系的输出口， 此已调信息能够通过实际的光纤发送出去， 而对于没有实际光纤连接关系的 输出口， 此已调信息是发送不出去的。 上游单板在定时 （例如， 每隔 3秒） 发送出去本单板的光纤连接关系以后，正常情况下会收到一个响应的"连接信 息包"。而所有的输入光口则监听和接收上游单板所发送过来的 "连接信息包，， 情况， 并在正常光纤连接的情况下， 回应一个包含本单板有关信息的"连接信 息包"。 在本优选实施例中， 放大单板 1的单板输出口检测模块 217会将本单板 的有关信息 （如上所述） 调制到一个固定的载波上面， 然后通过单板的所有 输出端口一 OUT1 口和 OUT2口发送出去。 对于 OUT1 口而言， 由于有实际 的光纤连接， 此已调信息能够传送到对端功率分配单板 4的 IN2口。 对于 OUT2口而言， 由于没有实际的光纤连接， 所以已调信息是发送不出去的。 另外， OUT1 口在发送出本单板的"连接信息包"以后， 会收到下游单板功率 分配单板 4的 IN2口所响应的一个 "连接信息包"， 该信息包中包含了当前功 率分配单板 4的一些属性信息及输入光口的使用情况 （比如， IN2口当前与 放大单板 1的 OUT1 口相连， 其他输入光口 IN1、 IN3、 IN4没有光纤连接， 闲置可用；)。 对于输入口一 IN1和 IN2而言， IN1 口会收到上游单板发送过来 的 "连接信息包"信息， 并且会将本单板的有关信息调制到一个固定的载波上 面发送出去， 即响应一个本单板的"连接信息包"信息。 IN2口由于没有光纤 连接， 所以不会监听到"连接信息包"信息。 然后， 放大单板 1的单板信息模 块 216和单板输入口监测模块 218和单板输出口监测模块 217会分别定时（例 如， 每隔 4秒） 给单板连接信息模块 42上报目前单板的有关属性信息和接 收到的上下游连接信息包。 单板连接信息模块 42首先判断收到的连接信息 包信息是否是上次最新上报给网络管理装置 22的， 如果是就上报， 否则， 不予上报。 由于是首次上报连接信息， 所以会将上述信息包信息上报给网络 管理装置 22。 放大单板 2的情况与此类似， 只是其 OUT1 口收到的连接信息 包是功率分配单板 4的 OUT8口发送过来的， 并且信息包中包含的连接信息 是放大单板 2的 OUT1 口和功率分配单板 4的 OUT8口相连。 功率分配单板 4中的单板信息模块 216会包含本单板目前的所有应有信息， 然后， 功率分 配单板 4的输出口信息检测模块 217会将单板信息模块 216中的信息调制到 一个固定的载波上去， 然后通过所有的输出光口发送出去 （比如， 输出光口 为 OUT1 OUT8 )发送出去， 由于只有 OUT1、 OUT8口有光纤连接关系， 所以这些光口发送的 "连接信息包 "信息会发送到与之相连的单板和端口， 并 且会收到回应的"连接信息包"信息。 功率分配单板 4的输入口只有 IN2口会 监听到 "连接信息包"信息， INI、 IN3、 IN4口则不会收到连接信息包， 表明 其空闲可用没有光纤连接关系。 然后功率分配单板 4中的单板信息模块 216、 单板输入口检测模块 218和输出口信息检测模块 217会分别定时 （例如， 每 隔 4秒） 向其单板连接信息模块 42上 4艮目前本地单板和上下游单板的连接 信息包信息。 单板连接信息模块 42首先判断收到的连接信息包信息是否是 上次最新上报给网络管理装置 22的， 如果是就上报， 否则， 不予上报。 由 于是首次上报连接信息， 所以， 单板连接信息模块 42会上报上述信息包信 息， 其中就包括所有的光纤连接关系。 波长选择单板 6也会做如上面所述的 流程， 光纤连接关系信息是波长选择单板 6只有输入端口 IN1 口有光纤连接 关系， 而输出口没有光纤连接关系。 网络管理装置 22在收到上述的单板属性信息和光纤连接关系信息后， 首先将这些信息与实安板光纤连接关系数据表中的信息进行比较， 发现放大 单板 1的 OUT1 口与功率分配单板 4的 IN2口相连的这条光纤连接， 单板类 型、 光口类型、 信息速率等信息都匹配， 在实安板光纤连接关系数据表中存 在。 所以， 网络管理装置 22判断此光纤连接关系正确， 在网络管理装置 22 界面上以正常的图形或文本数据表格的形式显示出来， 并将此光纤连接所对 应的单板和光口故以标记 (表明放大单板 1的 OUT1 口与功率分配单板 4的 IN2口已经有光纤连接关系， 这两个口已经不可用了）。 而对于放大单板 2的 OUT1 口与功率分配单板 4的 OUT8口相连的这条光纤连接， 网络管理装置 22发现单板类型匹配， 但端口类型不匹配， 在实安板光纤连接关系数据表中 没有这种光纤连接关系。 所以， 网络管理装置 22在其界面上显示时会给予 特殊的显示 （例如， 显示的线条颜色为红色）。 然后， 网络管理装置 22再按 照先上游单板再下游单板的原则进行建议性的光纤连接匹配， 所以先从放大 单板 2开始， 然后再按照单板类型匹配、 光口类型匹配、 信息速率匹配、 最 小距离准则 （在等距条件下， 按照上面网络管理装置 22数据库中所介绍的 准则条件进行判断） 等原则下寻找可匹配的单板和可用的光口， 发现距离其 最近的可匹配单板是功率分配单板 4 , 并且该单板有与放大单板 2的 OUT1 口匹配的端口一 IN1 口、 IN3口、 IN4口。 对于有多个同类型的可匹配端口的 情况， 按照端口的序号由小到大依次进行匹配。 所以， 网络管理装置 22会 将放大单板 2的 OUT1 口与功率分配单板 4的 IN1 口进行匹配， 给予一个建 议性的光纤连接关系，即，将放大单板 2的 OUT1 口与功率分配单板 1的 IN1 口相连接。 但是， 网络管理装置 22不会对建议性的光纤连接关系所对应的 单板和光口在实安板光纤连接关系数据表中 #丈标己。 对于波长选择单板 6而 言， 上报的连接信息包中单板的 OUT1 口没有光纤连接关系， 然后网络管理 装置 22会按照单板类型匹配、 光口类型匹配、 信息速率匹配、 最小距离准 则 (在等距条件下， 按照上面网络管理装置 22数据库中所介绍的准则条件 进行判断） 等原则在实安板光纤连接数据信息表中自动搜索一个最优的光纤 连接匹配光纤， 结果发现放大单板 3的 IN1 口是一个最佳选择。 所以， 网络 管理装置 22会将波长选择单板 6的 OUT1 口与放大单板 3的 IN1 口进行相 连， 并且在网络管理装置 22界面上以特殊的图形或文本数据表格的方式显 示出来 （例如， 光纤连接的颜色为蓝色等）。 至此， 本优选实施例已经将实际的光纤连接关系自动发现完毕， 并且将 正确的、 错误的以及单板只有一端有光纤连接关系的所有情况都故出了相应 的分析、 判断和处理， 并显示实际的单板光纤连接信息， 实时同步更新最新 的光纤连接关系。 其中， 对于实际错连的光纤连接关系， 网络管理装置 22 给予信息提示（例如， 自动发现的错误连纤给予红色显示）， 并且在还有其他 可用单板或端口的情况下， 给予一个建议性的光纤连接关系 （例如， 给予蓝 色显示）； 对于只有一端连接关系 （例如， 上游端或下游端， 即， 输入口和输 出口连接关系） 的单板， 在它和其他单板都还有可用端口的情况下， 也给出 一个建议性的连接关系。 由此可见， 该实施例可以警示一些仅靠人工不易监 测出来的光纤连接状况（例如， 出现光纤的断裂等情况）， 并且易于对系统的 光纤连接进行检错、 纠错， 可以提供系统的智能性， 降低人力资源和系统使 用、 维护的成本。 综上所述， 本发明实施例克月艮了相关技术中存在的不能自动获取光网络 内部光纤连接关系的缺陷， 提供了一种光纤连接的检测方案， 即， 在节点的 实际物理光纤连接好以后， 在网络管理装置 22上就能自动获取这些连接信 息， 校验实际光纤的错连、 断裂或者单板实际只有一端连接关系的情况， 并 且对于上述情况在单板还有可用端口连接的情况下， 给予一个建议性的连接 关系的方法。 因此， 本发明实施例是光网络智能化的重要体现， 也是实现光 网络的有关 SPC业务向最终的 SC业务演进的一个重要过程。 显然， 本领域的技术人员应该明白， 上述的本发明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， 可以将它们存储在存储装置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。 这样， 本发明不限制于任何特定的硬件和软件 结合。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本 领域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的^"神和 原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护 范围之内。
