处理模块 44 , 耦合至分析模块 42、 板内倒换决策模块 344和板间倒换决策 模块 322 , 设置为在分析模块 42确定所属的 MSP组的类型为板内保护组的 情况下, 将网络管理设备配置的 MSP组的信息下发到与板内保护组对应的 线卡;以及在分析模块 42确定所属的 MSP组的类型为板间保护组的情况下, 将网络管理设备配置的 MSP组的信息发送给板间倒换决策模块 322。 优选地, 主控板 32还包括: 板间倒换决策模块 322 , 耦合至板内倒换决 策模块 344和处理模块 44 ,设置为在接收到来自板内倒换决策模块 344发送 的上述告警信息后, 通过板间通讯方式指示板间保护组中的端口进行倒换。 优选地, 板内倒换决策模块 344还设置为根据其端口的上报的告警信息 在判定需要进行倒换的情况下, 指示板内保护组中的端口进行倒换。 优选地, 板间倒换决策模块 322还设置为通过消息队列指示板间保护组 中的端口进行倒换。 此外, 本发明实施例还提供了一种复用段保护的倒换系统。 图 5是根据 本发明实施例的复用段保护的倒换系统的结构框图, 如图 5所示, 该复用段 保护的倒换系统 50包括网络配置设备 52和上述 PTN设备 30 , 其中, 网络 配置设备 52包括: 设置模块 522 , 耦合至 PTN设备 30, 用于配置复用段保 护 MSP组的信息, 并该信息将下发给 PTN设备 30。 下面结合优选实施例和附图对上述实施例的实现过程进行详细说明。 优选实施例一 图 6是才艮据本发明优选实施例一的 MSP处理方案^ I架的示意图,如图 6 所示, 本实施例的处理框架可以分为两部分: 配置阶段和 MSP倒换处理阶 段。 具体地, 配置阶段可以包括如下步骤: 步骤 1 , 网络管理单元设置 MSP保护组信息, 信息下发给保护组信息分 析单元。 步骤 2, 保护组信息分析单元对收到的 MSP保护组信息进行分析, 如果 保护组中的端口涉及到多个保护板, 转步 4聚 3; 如果保护组中的端口在同一 个单板中, 转步 4聚 4。 步骤 3 ,保护组信息分析单元将保护组信息传递给 MSP板间倒换决策单 元。 步骤 4,保护组信息分析单元将保护组信息传递给 MSP板内倒换决策单 元。 而对于 MSP倒换处理阶段, 下面可以分别按照板间倒换和板内倒换进 行描述。 ①板间倒换处理过程: 板间保护组内的端口将状态信息通过单板间通讯 的方式传递给 MSP板间倒换决策单元(即, 对应图 6中信息 B ), MSP板间 倒换决策单元将分析的结果通过单板间通讯的方式传递给板间保护组内的端 口 (即, 对应图 6中信息 A )。
②板内倒换处理过程: 板内保护组内的端口将状态信息直接通知 MSP 板内倒换决策单元, (即, 对应图 6中信息 D ), MSP板内倒换决策单元将分 析的结果直接传递给各个端口 (即, 对应图 6中信息 C )。 可见, 本实施例将 MSP保护区分为板内保护和板间保护, 其中, 板内 保护的决策和倒换在单板内部进行,由于无需进行多个单板之间信息的交互, 处理效率有很大提高;板间保护的决策和倒换与相关技术中的处理基本相同, 但由于减少了单板间通讯的信息量, 从而达到提高 MSP倒换效率的作用。 优选实施例二 本实施例以 PTN设备为例, 详细说明复用段保护的倒换方法的处理流 程。 这里^ _设需要设置两个 MSP保护组, 其中一个保护组 A中包括线卡 a 端口 1、 端口 2, 另一个保护组 B中包括线卡 a端口 3和线卡 b端口 2。 图 7 是根据本发明优选实施例二的 PTN设备 MSP处理框架的示意图, 如图 7所 示, 配置步 4聚可以包括如下步 4聚: 步骤 S702, 网络管理单元配置 MSP保护组, 信息下发到保护组信息分 析单元, 转步骤 S704。 步骤 S704, 保护组信息分析单元根据保护组中端口的位置, 判断保护组 A属于板内倒换, 转步骤 S706; 判断保护组 B属于板间倒换, 转步骤 S710。 步骤 S706, 保护组信息分析单元将保护组 A信息下发到线卡 a, 转步骤 S708。 步骤 S708, 在线卡 a中建立 MSP保护组 A, 并创建决策单元 ProcA。 步骤 S710, 保护组信息分析单元将保护组 B信息发送到主控, 转步骤 S712。 步骤 S712, 在主控中建立 MSP保护组 B , 并创建决策单元 ProcB。 倒换步骤可以包括: ①保护组 A中, 线卡 a的端口 1和端口 2检测端口接收信息, 然后传递 给决策单元 ProcA, ProcA决策是否进行倒换, 并通知这两个端口的发送信 息。
②保护组 B中, 线卡 a的端口 3和线卡 b的端口 2接收信息, 然后用消 息队列的方式传递给主控, 主控将消息队列解析后, 传递给 ProcB, ProcB 决策是否进行倒换, 然后将倒换信息通过消息队列分别发送给线卡 a和线卡 b, 最后线卡 a和线卡 b分别将消息队列信息解析后传给各自的端口。 需要说明的是, 本发明实施例中的板内保护组是指配置的 MSP保护, 所涉及的端口在同一个保护板中的保护组; 板间保护组是指配置的 MSP保 护, 所涉及的端口在不同保护板中的保护组; 板内倒换是指板内保护组中发 生的倒换; 板间倒换是指板间保护组中发生的倒换。 综上所述,本发明实施例涉及光通讯行业中需要进行复用段保护的设备, 提供了一种提高复用段保护倒换效率的方案, 釆用区分 MSP组类型的方式, 将板内保护组的决策和倒换在单板内部进行, 解决了相关技术中单板间通讯 处理速度不及时及 MSP倒换时间过长的问题, 减少了单板间通讯的信息量, 提高了系统的处理效率。 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, 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。
