近几年来， 随着互联网业务的快速发展， 宽带接入技术不断进步， 光 纤光缆行业迎来高速发展的时期。 在该行业中光纤配线架 （ Optical Distribution Frame , ODF ) 用于光纤通信系统中光缆的成端和分配。 ODF 一般可以进多条光缆， 每条光缆可以来自不同的 ODF， 且光缆一般都会 熔接成端，这样两台 ODF之间的端口就会有连接关系。实际应用于中 ODF 之间的端口的连接关系特别重要， 这样就需要对 ODF之间的端口的连接 关系进行识别与记录。 目前对 ODF之间的端口的连接关系的识别主要是 人工使用光信号进行识别， 例如： 人工在一个 ODF设备中选择一个托盘 的一个端口， 并将光信号注入该端口， 并 i己录该端口的端口号； 另一人在 另一个 0DF设备对各端口进行探测， 当探测到某到端口存在光信号时， 记录该端口的端口号。这样就可以将发送光信号的端口和接收光信号的端 口记录， 从而识别出这两端口的连接关系。 在上述技术中， 由于两台 ODF 设备都需要有人， 且针对每个端口进行需要注入光信号， 这样识别端口的 连接关系的效率就很低， 且人工记录方式也容易出错。 发明内容

具体实施方式
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 有作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。
请参阅图 1， 图 1是本发明实施例提供一种端口的连接关系识别方法 的流程示意图， 如图 1所示， 包括以下步骤：
101、 获取端口组中的光纤的距离信息， 并将所述距离信息发送给网 管设备， 所述距离信息用于使所述网管设备识别远端， 其中， 所述远端为 向所述网管设备上报的端口组的光纤的距离与所述距离信息表示的距离 相等的光纤配线装置。
可选的， 上述端口组可以是光纤配线装置中任意一个端口组， 其中， 该终端组中各端口中的光纤的距离可以是相等的。 例如： 上述端口组为同 一个托盘中的端口。 另外， 光纤的距离可以理解为该光纤的长度， 即上述 距离信息可以理解为长度信息。由本实施例中光纤可以是连接于两个光纤 配线装置之间，这样该光纤的长度就可以理解为这两个光纤配置装置之间 的距离， 可以理解为该光纤的距离。 另外， 上述距离相等可以理解为两个 光纤配线装置向网管设备上报的距离大约相等，或者两者上报的距离之间 的差值小于一定预设阔值。 因为在实际应用于由于各种原因， 比如每条光 纤在熔接的时候留的余长会不等、 所用的尾纤长度有所差别、 比如每次测 试的偏差等等都会导致测试出来的光纤长度会有不同，所以这个距离相等 (光纤长度相等） 实际上是一个大约相等的概念。 另外，由于光纤配线装置可以通过光纤与多个不同的光纤配线装置连 接， 具体可以参考图 2。 在图 2中， ODF1通过可以通过光缆 1、 光缆 2、 光缆 3和光缆 4分别与 ODF5、 ODF4、 ODF3和 ODF2连接。 这里需要说 明的是， 由于光缆中包含光纤， 所以上述连接也可以理解为通过上述光缆 中的光纤连接。 另外， ODF1还可以引入光缆 5， 但光缆 5的远端还没有 与任何 ODF设备连接， 但本实施例中同样可以通过测控距离对其进行记 录。 另外， 在实际应用中， 不同的 ODF所处的位置往往都是有区别的， 这样上述光缆 1、 光缆 2、 光缆 3和光缆 4的长度就可以代表 ODF1与其 他 ODF之间的连接关系。 例如： ODF1对光缆 1、 光缆 2、 光缆 3、 光缆 4和光缆 5进行长度测量， 得到每个光缆的长度。 同理， ODF5也可以对 光缆 1的长度进行测量， ODF4对光缆 2的长度进行测量， ODF3对光缆 3 的长度进行测量， 以入 ODF2 对光缆 4 的长度进行测量。 这样当两个 ODF测量得到光缆的长度相同时， 就可以说明这两个 ODF之间通过光缆 连接。另外，对于光缆 5只在 ODF对其进行长度测量，而没有第二个 ODF 对其进行长度测量， 那么， 就可以得出光缆 5的远端还没有与任何 ODF 设备连接。 另外， 一个 ODF中存在多条光缆的长度相同时， 就可以将这 些光缆识别为连接同一 ODF的光缆， 即可以将这些光缆中光纤的端口理 解为一个端口组， 或者多个连接同一个 ODF的端口组。 例如： 所述方法 还可以包括如下步骤：
对多个端口的光纤进行距离探测，将所述多个端口中探测得到的距离 相同的端口作为所述端口组。
102、 接收所述网管设备发送的用于通知存在所述远端的通知消息。 当网管设备接收到步骤 101发送的距离信息，以及接收到其他光纤配 线装置发送的距离信息时，就可以在这些其他光纤配线装置中选择上报的 端口组的光纤的距离与上述距离信息表示的距离相等的光纤配线装置，将 该光纤配线装置作为远端， 并发送上述通知消息。
可选的，当网管设备未检测到上报的端口组的光纤的距离与上述距离 信息表示的距离相等的光纤配线装置时，网管设备可以返回通知不存在所 述远端的通知消息。 例如： 步骤 101上报图 2所示的光缆 5的距离信息， 这样网管设备就无法检测到对应的光纤配线装置。 另外， 针对 G5网络， 由于网管设备无法查过出相等距离的光纤配线装置， 这样本实施例识别
G5 网络中的光纤没有与远端连接， 并记录。 另外， 针对于 G6 网络， 光 纤的距离可略为 0， 本实施例中， 可以确认 G6网络中的光纤未连接。
103、 向所述端口组中的源端口发送探测信号， 以使所述远端在目的 端口接收到所述探测信号。
当步骤 102 接收到上述通知消息时就表示上述端口组中的光纤与光 纤配线装置连接， 从而步骤 103就可以发送上述探测信号。 这里需要说明 的是， 步骤 102接收到的通知消息可以仅用于通知存在所述远端， 即仅用 于通知上述端口组中的光纤与光纤配线装置连接了，但该通知消息可以不 指定具体与哪个光纤配线装置连接。 当然， 在一些场景中， 上述通知消息 也可以携带上述远端的标识信息，以告知上述端口组中的光纤与哪个光纤 配线装置连接。
可选的， 上述探测信号可以任意能够实现探测功能的信号， 例如： 光 信号或者电信号等。
104、向所述网管设备发送携带有所述源端口的端口标识的探测消息， 以使所述网管设备根据所述端口标识确认所述源端口与所述目的端口的 连接关系。
当网管设备接收到上述探测消息时，就可以基于端口标识确认所述源 端口与所述目的端口的连接关系。 其中， 上述确认所述源端口与所述目的 端口的连接关系可以是建立所述源端口与所述目的端口的连接关系并记 录， 或者记录所述源端口与所述目的端口的连接关系。
可选的， 上述方法可以应用于任何连接有光纤的装置， 例如： 光纤配 线装置，其中，光纤配线装置可以是 ODF，或者自动光纤配线架（ Automatic Optical Distribution Frame , AODF )。
上述网管设备可以是任何具备通信设备的设备， 例如： 服务器、 计算 机、 笔记本电脑、 基站设备等等。
本实施例中， 获取端口组中的光纤的距离信息， 并将所述距离信息发 送给网管设备， 所述距离信息用于使所述网管设备识别远端， 其中， 所述 远端为向所述网管设备上报的端口组的光纤的距离与所述距离信息表示 的距离相等的光纤配线装置；接收所述网管设备发送的用于通知存在所述 远端的通知消息； 向所述端口组中的源端口发送探测信号， 以使所述远端 在目的端口接收到所述探测信号；向所述网管设备发送携带有所述源端口 的端口标识的探测消息，以使所述网管设备根据所述端口标识确认所述源 端口与所述目的端口的连接关系。这样可以通过光纤的距离识别出两个连 接的光纤配线装置， 再通过发送探测信号， 识别出两连接的端口， 从而确 认这两个端口的连接关系。从而本发明可以提高端口的连接关系识别的效 率， 以及提高识别的准确性。
请参阅图 3， 图 3是本发明实施例提供另一种端口的连接关系识别方 法的流程示意图， 如图 3所示， 包括以下步骤：
301、 对端口组中的至少一个端口的光纤进行距离探测， 将所述探测 获取的距离信息作为所述端口组中的光纤的距离信息，并将所述距离信息 发送给网管设备， 所述距离信息用于使所述网管设备识别远端， 其中， 所 述远端为向所述网管设备上报的端口组的光纤的距离与所述距离信息表 示的距离相等的光纤配线装置。
可选的， 上述端口组可以理解为一个托盘中的端口的组合， 或者一条 光缆中一条子管中包括的所有光纤（或者理解为纤芯）的端口的组合， 或 者一条光缆中所有光纤的端口的组合。 另外， 需要限定的是， 上述端口组 的中各端口的中光纤的距离都是相等的。
可选的，上述对端口组中的至少一个端口的光纤进行距离探测可以是 对该端口组中的一个端口的光纤进行探测，将该光纤的距离作为该端口组 的各端口的光纤的距离。 因为在实际应用中， 同一个托盘或者同一个子管 中的光纤往往都是与同一个光纤配线装置连接，这样同一个托盘或者同一 个子管中的光纤的距离就是相等的。 另外， 上述对端口组中的至少一个端 口的光纤进行距离探测可以是对该端口组中的多个端口或者每个端口的 光纤进行距离探测， 从而得到多个探测距离， 若这多个探测距离相等时， 其中任意一个距离信息可以作为所述端口组中的光纤的距离信息；若这多 个探测距离存在不相等的距离时，将这多个探测距离中相等距离对应的端 口作为同一个端口组，这样可以步骤 301中的端口组又分为多个不同的端 口组， 再针对这多个不同端口组进行端口的连接关系的确认。
可选的， 可以釆用通过发送光信号进行探测， 例如： 通过计算光信号 在光纤中传输时的瑞利散射和菲涅尔反射所产生的背向散射得到光纤的 距离。 具体可以釆用光时域反射仪 （ Optical Time Domain Reflectometer , OTDR ) 对光纤的距离进行探测。
302、 接收所述网管设备发送的用于通知存在所述远端的通知消息。
303、 向所述端口组中的源端口发送探测信号， 以使所述远端在目的 端口接收到所述探测信号。
可选的， 当接收到上述通知消息后， 就可以进入通信模式， 向所述端 口组中的源端口发送探测信号。
可选的， 由于一个端口组中可以包括多个端口， 这样本实施例可以按 照光纤顺序进行探测。 因为在实际应用中， 光缆熔接往往是通过光纤顺序 进行熔接的， 最终成端到面板上也是如此。 例如： 某一个端口组包括 48 芯光纤， 如图 4所示， 可以熔接到如图 4所示的 A、 B、 C和 D四个端口 模块，其中，熔接的顺序可以按照 A1至 A12， B 1至 B 12， C1至 C12和 D1 至 D12的顺序进行熔接。 这样步骤 303选择端口发送探测信号的顺序就 可以按照上述顺序进行发送，远端也可以按照上述熔接顺序选择端口进行 接收。 这样发送探测信号和选择端口接收探测信号都按照熔接规则进行， 从而可以快速对端口的连接关系进行识别。 例如： 步骤 303 第一个选择 A1 端口发送探测信号， 而远端第一个选择 A1 端口接收探测信号， 这样 可以实现远端当前选择接收探测信号的端口为是步骤 303 当前发送探测 信号的端口， 从而避免远端当前选择接收探测信号的端口不是步骤 303 当前发送探测信号的端口的问题。 当然， 由于考虑到熔接过程出错的反序 的问题， 本实施例还可以按照熔接顺序的反序进行探测， 直到探测完所有 端口， 即实现双方握手成功。 当然， 这里熔接可以是人工操作的， 即熔接 的顺序可以是多种。 那么， 步骤 303选择端口发送探测信号的顺序也可以 是多种， 此处不——说明。 另外， 上述源端口可以是上述端口组中任意一 端口， 且步骤 303可以对多个或者所有端口发送探测信号， 其中， 发送的 顺序参考上述描述的顺序。
可选的，步骤 303的探测顺序还可以是两台光纤配线装置进行预先进 行协商的，即对端口进行探测的顺序可以是两台光纤配线装置预先协商好 的， 从而实现两台光纤配线装置的策略握手。 另外， 上述源端口可以是接入的光纤成端的端口， 其中， 光纤成端可 以理解为光纤通过尾纤与连接头连接。 例如： 如图 5所示， 光缆可以包括 多条子管， 每条子管可以包括多条纤芯（图 5中的纤芯可以理解为光纤；)， 在适配器面板内， 纤芯通过熔接点与尾纤连接， 尾纤再与接连头连接， 连 接头可以用于插入适配器的端口内。
可选的， 步骤 303可以每次对一个端口发送探测信号， 发送完一个端 口的探测信号后， 可以通过跳纤， 将探测信号发送至另一个端口。
可选的， 当在对端口进行探测的过程中碰到熔接错误， 即存在一个或 者多个端口没有按照熔接规则进行熔接， 例如： 人工熔接错误， 导致某些 端口互换了， 如原本该熔接到 A1 端口的光纤被熔接到 A2， 再原本该熔 接到 A2端口的光纤被熔接到 Al。 这样按照熔接规则进行探测， 以及远 端按照熔接规则进行接收时， 就对熔接错误的端口无法探测成功， 这样本 实施例， 可以釆用轮询机制， 将未配对的端口依次扫描， 即可得到正确的 连接关系，以避免由于人工熔接错误带来的或者系统资源不对应带来的可 能的业务开不通和资源的沉没问题。
这样会导致按照熔接规律的端口无法探测成功，
304、向所述网管设备发送携带有所述源端口的端口标识的探测消息， 以使所述网管设备根据所述端口标识确认所述源端口与所述目的端口的 连接关系。
可选的， 步骤 304可以包括：
向所述网管设备发送用于通知当前发送所述探测信号的端口为所述 源端口的探测消息，以使所述网络设备在接收到所述远端发送的用于通知 当前接收到所述探测信号的端口为所述目标端口的探测消息时，确认所述 源端口与所述目的端口的连接关系。
其中，上述探测消息可以是对在上述源端口发送完探测信号后发送的 探测消息， 例如： 每个一个端口发送完探测信号， 就向网管设备发送针对 该端口的探测消息，以让网管设备及时知道当前发送探测信号的端口为哪 个端口。 同时， 远端在接收到探测信号后， 也会向网管设备发送用于通知 当前接收到所述探测信号的端口为所述目标端口的探测消息，这样网管设 备就可以及时将两个端口确认连接关系。 该实施方式中， 上述源端口中的光纤可以是单纤单向通信， 即上述端 口只用于发送探测信号。
可选的， 所述方法还可以包括如下步骤：
接收所述远端发送的用于通知当前接收到所述探测信号的端口为所 述目标端口的响应消息；
步骤 304可以包括：
向所述网管设备发送用于通知所述源端口与所述目标端口的连接关 系的探测消息，以使所述网管设备确认所述源端口与所述目的端口的连接 关系。
其中，上述接收到远端发送的通知消息可以是在上述源端口中接收到 该通知消息， 即在该源端口中可以实现双向通信。 具体可以是上述源端口 与目的端口之间的光纤为单纤双向通信的光纤。
该实施方式中，可以实现由光纤配线装置向网管设备发送通知所述源 端口与所述目标端口的连接关系的探测消息，这样网管设备只需要进行确 认也记录的就可以。 另外， 由于两台光纤配线装置之间可能会连接多条光 纤， 即存在多个端口的连接关系， 这样本实施方式， 就可以在所有的端口 都探测完成后， 统一向网管设备上报探测结果， 即统一向网管设备上报两 台光纤配线装置之间的所有商品的连接关系。从而可以减少光纤配线装置 与网管设备之间的信息交互， 从而节约网络资源。
可选的， 所述方法还可以包括如下步骤：
接收所述网管设备发送的用于询问当前发送所述探测信号的端口的 询问请求消息；
步骤 304可以包括：
响应所述询问请求消息，以向所述网管设备发送用于通知当前发送所 述探测信号的端口为所述源端口的探测消息，以使所述网络设备在接收到 所述远端发送的用于通知当前接收到所述探测信号的端口为所述目标端 口的探测消息时， 确认所述源端口与所述目的端口的连接关系。
该实施方式， 可以实现由网管设备主动触发探测消息的上报。 另夕卜， 还可以实现网管设备及时确认进行探测的两个端口的连接关系。
本实施例， 在图 1 所示的实施例的基础上增加了多种可选的实施方 式， 且都可以实现提高端口的连接关系识别的效率， 以及提高识别的准确 性。
请参阅图 6， 图 6是本发明实施例提供的另一种端口的连接关系识别 方法的流程示意图， 如图 6所示， 包括以下步骤：
601、 获取端口组中的光纤的距离信息， 并将所述距离信息发送给网 管设备， 所述距离信息用于使所述网管设备识别源端， 其中， 所述源端为 向所述网管设备上报的端口组的光纤的距离与所述距离信息表示的距离 相等的光纤配线装置。
可选的， 上述端口组可以是光纤配线装置中任意一个端口组， 其中， 该终端组中各端口中的光纤的距离可以是相等的。 例如： 上述端口组为同 一个托盘中的端口。 另外， 光纤的距离可以理解为该光纤的长度， 即上述 距离信息可以理解为长度信息。由本实施例中光纤可以是连接于两个光纤 配线装置之间，这样该光纤的长度就可以理解为这两个光纤配置之间的距 离， 可以理解为该光纤的距离。
另外，由于光纤配线装置可以通过光纤与多个不同的光纤配线装置连 接， 具体可以参考图 2。 在图 2中， ODF1通过可以通过光缆 1、 光缆 2、 光缆 3和光缆 4分别与 ODF5、 ODF4、 ODF3和 ODF2连接。 这里需要说 明的是， 由于光缆中包含光纤， 所以上述连接也可以理解为通过上述光缆 中的光纤连接。 另外， ODF1还可以引入光缆 5， 但光缆 5的远端还没有 与任何 ODF设备连接， 但本实施例中同样可以通过测控距离对其进行记 录。 另外， 在实际应用中， 不同的 ODF所处的位置往往都是有区别的， 这样上述光缆 1、 光缆 2、 光缆 3和光缆 4的长度就可以代表 ODF1与其 他 ODF之间的连接关系。 例如： ODF1对光缆 1、 光缆 2、 光缆 3、 光缆 4和光缆 5进行长度测量， 得到每个光缆的长度。 同理， ODF5也可以对 光缆 1的长度进行测量， ODF4对光缆 2的长度进行测量， ODF3对光缆 3 的长度进行测量， 以入 ODF2 对光缆 4 的长度进行测量。 这样当两个 ODF测量得到光缆的长度相同时， 就可以说明这两个 ODF之间通过光缆 连接。另外，对于光缆 5只在 ODF对其进行长度测量，而没有第二个 ODF 对其进行长度测量， 那么， 就可以得出光缆 5的远端还没有与任何 ODF 设备连接。 另外， 一个 ODF中存在多条光缆的长度相同时， 就可以将这 些光缆识别为连接同一 0DF的光缆， 即可以将这些光缆中光纤的端口理 解为一个端口组， 或者多个连接同一个 ODF的端口组。 例如： 所述方法 还可以包括如下步骤：
对多个端口的光纤进行距离探测，将所述多个端口中探测得到的距离 相同的端口作为所述端口组。
602、 接收所述网管设备发送的用于通知存在所述源端的通知消息。
603、 在所述端口组中的目的端口接收所述源端在源端口发送的探测 信号。
可选的， 目的端口可以是预先默认接收探测信号的端口， 例如： 上述 源端口为第一个发送探测信号的端口， 即进行的第一次探测， 这样步骤 603就可以选择默认第一个接收探测信号的端口接收上述探测信号， 当该 端口接收到上述探测信号时， 就表示这两个端口存在连接关系。 另外， 当 确认这两个端口的连接关系后， 源端会再选择一个端口发送上述探测信 号， 这样步骤 603同样也会再选择一个端口接收探测信号。 其中， 这里选 择过程具体可以参考图 3所示的实施例中介绍的探测顺序，此处不作重复 说明。
可选的， 当选择的端口没有接收到上述探测信号时， 步骤 603可以选 择其他端口接收上述探测信号， 直到通过某一端口接收到上述探测信号， 那么， 接收到上述探测信号的端口就为上述目的端口。
604、 发送用于通知当前接收到所述探测信号的端口为所述目标端口 的探测消息，以使所述网管设备确认所述源端口与所述目的端口的连接关 系。
可选的， 步骤 604发送的探测消息可以是向上述网管设备发送， 也可 以是向上述源端发送。 当然， 源端接收到该探测消息后， 源端会基于该探 测消息向网管设备发送消息，以使所述网管设备确认所述源端口与所述目 的端口的连接关系。
可选的， 上述方法可以应用于任何连接有光纤的装置， 例如： 光纤配 线装置， 其中， 光纤配线装置可以是 ODF， 或者 AODF。
本实施例中， 获取端口组中的光纤的距离信息， 并将所述距离信息发 送给网管设备， 所述距离信息用于使所述网管设备识别源端， 其中， 所述 源端为向所述网管设备上报的端口组的光纤的距离与所述距离信息表示 的距离相等的光纤配线装置；接收所述网管设备发送的用于通知存在所述 源端的通知消息；在所述端口组中的目的端口接收所述源端在源端口发送 的探测信号；发送用于通知当前接收到所述探测信号的端口为所述目标端 口的探测消息，以使所述网管设备确认所述源端口与所述目的端口的连接 关系。 这样可以通过光纤的距离识别出两个连接的光纤配线装置， 再通过 发送探测信号， 识别出两连接的端口， 从而确认这两个端口的连接关系。 从而本发明可以提高端口的连接关系识别的效率， 以及提高识别的准确 性。
请参阅图 7， 图 7是本发明实施例提供的另一种端口的连接关系识别 方法的流程示意图， 如图 7所示， 包括以下步骤：
701、 对所述端口组中的至少一个端口的光纤进行距离探测， 并将所 述探测获取的距离信息作为所述端口组中的光纤的距离信息，所述距离信 息用于使所述网管设备识别源端， 其中， 所述源端为向所述网管设备上报 的端口组的光纤的距离与所述距离信息表示的距离相等的光纤配线装置。
702、 接收所述网管设备发送的用于通知存在所述源端的通知消息。
703、 在所述端口组中的目的端口接收所述源端在源端口发送的探测 信号。
可选的， 上述目的端口可以是上述端口组中的任意端口。 其中， 步骤 703可以是在端口组中的端口中进行切换， 以实现对该端口组中所有端口 进行探测。 另外， 步骤 703可以是通过自动跳纤进行端口之间的切换。
704、 发送用于通知当前接收到所述探测信号的端口为所述目标端口 的探测消息，以使所述网管设备确认所述源端口与所述目的端口的连接关 系。
可选的， 步骤 704可以包括：
向所述网管设备发送通知当前接收到所述探测信号的端口为所述目 标端口的探测消息，以使所述网络设备在接收到所述源端发送的用于通知 当前发送所述探测信号的端口为所述源端口的探测消息时，确认所述源端 口与所述目的端口的连接关系。
这样当网管设备接收到上述探测消息时，就可以根据源端发送的用于 通知当前发送所述探测信号的端口为所述源端口的探测消息，确认所述源 端口与所述目的端口的连接关系。
可选的， 步骤 704可以包括：
向所述源端发送通知当前接收到所述探测信号的端口为所述目标端 口的探测消息，以使所述源端向所述网管设备发送用于通知所述源端口与 所述目标端口的连接关系的通知消息，所述通知消息用于使所述网管设备 确认所述源端口与所述目的端口的连接关系。
该实施方式中，上述源端口与目的端口之间的光纤可以是单纤双向通 信的光纤。
可选的， 步骤 703可以包括：
按照预先获取的所述源端发送所述探测信号的探测规则，选择在所述 端口组中最大可能接收到所述探测信号的端口作为目的端口，在所述端口 组中的目的端口接收所述源端在源端口发送的探测信号。
其中， 上述探测规则可以是与上述源端口预先协商好的， 这样可以实 现源端口发送探测信号的端口的顺序与步骤 703 接收探测信号的端口的 顺序一致， 从而可以快速完成端口的连接关系的探测。 例如： 上述源端口 为第一个发送探测信号的端口， 那么， 步骤 703就可以按照预先协商的探 测规则， 选择该规则中第一个接收探测信号的端口， 以检测该端口是否可 以接收到上述探测信号。 另外， 上述最大可能接收到所述探测信号的端口 可以理解为， 上述探测规则中源端当前发送探测信号的端口匹配的端口， 其中，该匹配的端口可以是端口标识或者端口名称或者端口位置一致的端 口 。 例如： 如图 4所示， 源端口第一个选择 A1端口发送探测信号， 那么， 步骤 703就会选择 A1端口为最大可能接收到所述探测信号的端口。
本实施例， 在图 6 所示的实施例的基础上增加了多种可选的实施方 式，都可以实现提高端口的连接关系识别的效率，以及提高识另 'J的准确性。

801、 接收源端发送的所述源端的端口组中的光纤的距离信息， 以及 接收远端发送的所述远端的端口组中的光纤的距离信息。
可选的， 步骤 801可以是接收多个光纤配线装置发送的距离信息， 该 距离信息可以表示各光纤配线装置引入的光纤的长度。
802、 当所述源端发送的距离信息与所述远端发送的距离信息表示的 距离相等时， 向所述源端发送用于通知存在所述远端的第一通知消息， 以 及向远端发送用于通知存在所述源端的第二通知消息。
可选的，步骤 802可以是将接收到多个光纤配线装置的距离信息进行 配对，以将距离信息表示的距离相等的两如光纤配线装置作为一对，因为， 当两台光纤配结装置的引入的光纤的长度相等时，就表示这两台光纤配线 装置的光纤是连接在一起的。 当配对成功后， 就可以向该配对的两台光纤 配线装置发送通知消息。
803、 接收所述源端发送的携带有源端口的端口标识的探测消息， 其 中，所述探测消息为所述源端向所述源端口发送探测信号之后发送的探测 消息。

该实施方式，可以 居源端探测消息确认所述源端口与目的端口的连 接关系。
可选的， 所述方法还可以包括如下步骤： 接收所述远端发送的用于通知当前接收到所述探测信号的端口为所 述目标端口的探测消息；

该实施方式， 可以主动向源端发送询问请求消息， 源端接收到该请求 消息时， 就可以向网管设备返回探测消息， 这样就可以根据源端探测消息 确认所述源端口与目的端口的连接关系。
可选的， 上述方法可以应用于网管设备。
本实施例中， 接收源端发送的所述源端的端口组中的光纤的距离信 息， 以及接收远端发送的所述远端的端口组中的光纤的距离信息； 当所述 源端发送的距离信息与所述远端发送的距离信息表示的距离相等时，向所 述源端发送用于通知存在所述远端的第一通知消息，以及向远端发送用于 通知存在所述源端的第二通知消息；接收所述源端发送的携带有源端口的 端口标识的探测消息， 其中， 所述探测消息为所述源端向所述源端口发送 探测信号之后发送的探测消息；根据所述端口标识确认所述源端口与目的 端口的连接关系， 其中， 所述目的端口为所述远端接收到所述探测信号的 端口。 这样可以实现提高端口的连接关系识别的效率， 以及提高识别的准 确性。
