( 2 ) 计算传输路径中相关联的单板端口; ( 3 ) 将单板端口与保护组进行匹配, 确定各个单板端口发生故障时需 要倒换的保护组。 在优选实施过程中, 网络管理***需要事先确定各个单板端口发生故障 时需要倒换的保护组, 即需要生成多保护组同时倒换的条件, 也就是说, 当 某个端口触发倒换时, 应同时有多少个保护组同时发生倒换。 通过上述处理, 能够判断出当前哪些保护组应该发生倒换, 从而可以确 定保护组是否全部执行了保护倒换, 有效提高了保护组保护倒换的成功率。 优选地, 在执行步骤 S204 的校验结果为是, 则网络管理***直接将校 -险结果返回至用户端。 通过上述处理, 可以实时提示用户保护倒换的状态, 从而可以提高用户 体验。 优选地, 上述步骤 S206可以进一步包括以下处理:
( 1 ) 保护控制器接收来自于网络管理***的未成功执行保护倒换的保 护组标识;
( 2 ) 保护控制器对保护组标识对应的保护组进行校验, 并将校验结果 反馈至网络管理***以生成日志;
( 3 ) 保护控制器对确认未成功执行保护倒换的保护组执行保护倒换操 作。 在优选实施过程中, 可以有两种实现方案, 第一种方案是: 当网络管理 ***校验后, 直接通知保护控制器对未成功执行保护倒换的保护组重复执行 保护倒换操作。 其中, 未成功执行保护倒换的保护组是网络管理***校验后 获得的 (具体可以参见上述步骤 S202-步骤 S206 )。 第二种方案是: 当网络管理***校验后, 将未成功执行保护倒换的保护 组标识发送至保护控制器, 保护控制器在对这些保护组标识对应的保护组进 行第二次校-险, 并对确认未成功执行保护倒换的保护组执行保护倒换操作。 例如, 网络管理***第一次校 -险有保护组 1、 保护组 3、 保护组 4未成功执 行保护倒换, 则将保护组 1、 保护组 3、 保护组 4的标识信息发送至保护控 制器, 保护控制器对保护组 1、 保护组 3、 保护组 4进行第二次校验, 或许 两次校-险结果相同, 则保护控制器对保护组 1、 保护组 3、 保护组 4执行保 护倒换操作; 或许两次校验结果不同, 保护控制器校验后, 只有保护组 1、 保护组 3未成功执行保护倒换操作, 则保护控制器对保护组 1、 保护组 3执 行保护倒换。 通过网络管理***与保护控制器的交互处理, 进行两次校验, 可以提高 校验的准确性, 从而可以提高后续执行保护倒换的工作效率。 优选地, 在执行步骤 S206之前, 还可以包括以下处理:
( 1 ) 网络管理***每隔预定时间段检测保护路径的告警状态;
( 2 ) 在每次检测后, 网络管理***通知保护控制器检测保护路径的告 警状态;
( 3 ) 如果网络管理***和保护控制器的检测结果不一致, 则网络管理 ***生成告警状态不一致提示事件;
( 4 ) 如果网络管理***和保护控制器的检测结果一致, 则网络管理系 统记录保护路径的告警状态;
( 5 ) 网络管理***根据检测结果确定能够执行保护倒换的保护路径。 通过上述处理, 网络管理***与保护控制器实时监测保护组中控制器单 板以及业务单板的状态, 保证控制器单板的运行状态与单板状态一致, 确定 能够执行保护倒换的保护路径,通过该方案可以进一步提高保护倒换成功率。 下面结合图 3进一步描述上述的优选实施例。 图 3为根据本发明实施例的网络管理***监测保护路径的流程图。 该监 测流程可以包括以下处理: 步骤 S302: 设备当前配置有保护组, 对业务进行保护, 网络管理***会 定时对保护路径进行监测, 并同时对保护控制器进行监测; 步骤 S304: 网络管理***定时监测保护路径的告警状态, 并同步将告警 状态信息通知给保护控制器进行二次校验; 步骤 S306: 若保护路径无告警, 且网络管理***的检测结果与保护控制 器检测结果一致, 则网管在日志中记录保护路径正常; 步骤 S308: 若保护路径无告警, 但网络管理***监测的结果与保护控制 器监测结果不一致, 则网管产生事件提示网管保护状态与保护控制器状态不 一致; 步骤 S310: 若保护路径有告警, 且网络管理***的检测结果与保护控制 器的检测结果一致, 则网管根据上报的告警给出事件提示保护路径异常。 步骤 S312: 若保护路径有告警, 但网络管理***监测的结果与保护控制 器监测结果不一致, 则网管产生事件提示网管保护状态与保护控制器状态不 一致及保护路径状态异常, 同时提示当前的告警状态。 通过上述处理, 实时地监测保护组中控制器单板以及业务单板的状态, 可以保证控制器单板的运行状态与单板状态一致。 确定哪些保护路径可以执 行保护倒换, 从而可以提高保护倒换的成功率, 并能够有效的减少运维人员 的维护作业时间。 图 4为才艮据本发明优选实施例的实现保护组保护倒换的方法的流程图。 该方法包括以下处理: 步骤 S402: 如果工作业务发生中断, 会根据保护业务的情况发生倒换, 若保护通道异常, 则不发生倒换; 步骤 S404: 若保护通道正常, 则发生倒换且上~¾倒换事件; 步骤 S406: 倒换完成后, 网络管理***根据上报的保护倒换事件进行保 护组倒换校 -险; 步骤 S408: 若保护组均正常倒换, 则网络管理***直接记录日志并实时 显示结果被用户; 步骤 S410: 如果还有保护组未成功执行保护倒换, 则网络管理***将异 常的保护组信息提供给保护控制器, 由保护控制器进行二次倒换校验; 步骤 S412: 保护控制器校验完成后, 上报相关信息给网络管理***, 并 由网络管理***生成日志记录校-险结果。 步骤 S414:保护控制器对确认的未成功执行保护倒换的保护组执行保护 倒换操作。 其中, 校验过程不仅校验保护组的倒换状态, 还要进行和保护控制器的 交互。 由此可知, 本实施例釆用上述第二种方案。 釆用第二种方案, 可以提 高校验正确性, 因为网络管理***是根据保护控制器上传的保护倒换事件进 行校验的, 在有多个保护组同时倒换的过程中, ***工作效率较低, 可能会 在上传过程中丢失报文, 因此在此情况下, 网络管理***的校验准确性可能 不 ι¾。 在优选实施过程中, 在步骤 S414 之后, 可能仍然存在保护组未成功倒 换的情况, 此时, 可以提示用户进行相关操作, 也可以继续对未成功倒换的 保护组进行保护倒换, 或者发送保护倒换事件给网络管理***, 重复执行校 验和倒换的操作。 具体可以根据情况而定。 为了帮助理解本发明的上述优选实施例, 下面进一步描述本发明的两个 实施例, 发明人经过测试, 发现取得了良好的效果。 实施例一
( 1 ) 当前工作业务和保护业务正在运行, 网管 (即网络管理***) 定 时监测保护业务的状态, 并同步与保护控制器进行通讯, 确保网管检测到的 保护业务状态与保护控制器检测到的保护业务状态完全一致。
( 2 ) 若检测结果完全一致, 且保护业务正常, 则网络管理***无任何 提示。
( 3 ) 若检测结果完全一致, 但是保护业务异常, 则网络管理***将异 常信息实时显示给用户。
( 4 ) 若检测结果不一致, 则网络管理***将不一致的信息生成对比的 表格实时显示给用户。 通过网管***与保护控制器交互对保护路径进行监测, 实时地监测保护 组中控制器单板以及业务单板的状态, 保证控制器单板的运行状态与单板状 态一致, 并且可以向用户实时呈现保护业务状态, 便于用户进行后续处理, 用户体险较好。 实施例二
( 1 ) 三个保护组的工作路径经过同一条线路, 此时线路中断, 保护控 制器触发倒换并上 ·ί艮倒换事件给网络管理***, 网络管理***收到倒换事件 后, 判断线路中断点, 并计算出此时应该倒换三个保护组。
( 2 ) 若此时三个保护组均上报倒换事件, 则认为保护组均正常倒换, 实时将结果显示给用户。
( 3 ) 若此时三个保护组有一个或多个未上 ·ί艮倒换事件, 网络管理*** 通知保护控制器对未倒换的保护组进行二次检验和二次倒换操作。
( 4 ) 若二次倒换后, 所有保护组都已经成功倒换, 则实时将结果显示 给用户。
( 5 ) 若二次倒换后, 仍有保护组未成功倒换, 则提示用户进行相关操 作。 通过网络管理***与保护控制器的两次校验, 能够判断出当前哪些保护 组应该发生倒换并检测保护组倒换状态是否正常, 达到了自动检测保护组倒 换状态的效果。 从而可以保证保护倒换的正确发生, 提高保护组保护倒换的 成功率, 并能够有效地减少运维人员的维护作业时间。 图 5为才艮据本发明实施例的实现保护组保护倒换的***的结构框图。 如 图 5所示, 该***包括以下装置: 保护控制器 50、 网络管理*** 52。 保护控制器 50 , 用于在对保护组执行保护倒换之后, 向网络管理***发 送保护倒换事件, 接收来自于网络管理***的通知对未成功执行保护倒换的 保护组重复执行保护倒换操作; 网络管理*** 52 ,用于根据接收到的保护倒换事件校验保护组是否全部 成功执行保护倒换, 如果没有全部成功执行, 则向保护控制器发送通知。 釆用本发明实施例的装置, 可以有效提高保护组保护倒换的成功率, 并 能够有效的减少运维人员的维护作业时间。 优选地,如图 6所示, 网络管理*** 52可以进一步包括: 确定装置 520, 用于确定需要执行保护倒换的保护组个数; 判断装置 524 , 用于判断上报的 保护倒换事件个数与保护组个数是否一致。 在优选实施过程中, 当工作路径的某个单板端口发生故障时, 网络管理 ***需要计算有多少个保护组需要执行保护倒换。 通过上述处理, 确定装置 520可以当前哪些保护组应该发生倒换, 判断 装置 524可以达到自动检测保护组倒换状态的效果。 优选地, 如图 6所示, 网络管理*** 52还可以包括: 业务路径计算装 置 526 , 用于计算各个业务的传输路径; 业务路径关联计算装置 528 , 用于 计算传输路径中相关联的单板端口; 多保护组同步倒换计算装置 530 , 用于 将单板端口与保护组进行匹配, 确定各个单板端口发生故障时需要倒换的保 护组; 事件提示装置 532 , 用于实时显示业务路径计算装置 526、 业务路径 关联计算装置 528和多保护组同步倒换计算装置 530的计算结果。 其中, 业务路径计算装置 526、 业务路径关联计算装置 528、 多保护组 同步倒换计算装置 530、 事件提示装置 532 以及多保护组同步倒换装置 542 (相当于保护倒换执行装置 506 ) 可以组成网络管理***的业务保护关联子 ***, 该业务保护关联子***具体可以参见图 7。 通过上述处理, 能够判断出当前哪些保护组应该发生倒换, 从而可以确 定保护组是否全部执行了保护倒换, 有效提高了保护组保护倒换的成功率。 优选地, 如图 6所示, 网络管理*** 52还可以包括: 发送装置 534 , 用 于在确定保护组已经全部成功执行保护倒换时, 直接将校 -险结果返回至用户 端。 通过上述处理, 可以实时提示用户保护倒换的状态, 从而可以提高用户 体验。 优选地, 如图 6所示, 保护控制器 50可以包括: 接收装置 500 , 用于在 网络管理***确定保护组未全部成功执行保护倒换时, 接收来自于网络管理 ***的未成功执行保护倒换的保护组标识; 校-险装置 502 , 用于对保护组标 识对应的保护组进行校验; 反馈装置 504 , 用于将校验装置的校验结果反馈 至网络管理***以生成日志; 保护倒换执行装置 506 , 用于对确认未成功执 行保护倒换的保护组执行保护倒换操作。 在优选实施过程中, 若保护组均正常倒换, 则网络管理***直接记录日 志并实时显示结果被用户; 在上述方法中, 若保护组存在倒换异常, 则网络 管理***将异常的保护组信息提供给保护控制器, 由保护控制器进行二次倒 换校验, 保护控制器校验完成后, 上报相关信息给网络管理***, 并由网络 管理***生成日志记录校验结果。 上述处理具体可以参见上述第二种方案。 通过网络管理***与保护控制器的交互处理 (即通过第二种方案处理), 进行两次校验, 可以提高校验的准确性, 从而可以提高后续执行保护倒换的 工作效率。 优选地, 如图 6所示, 网络管理*** 52还可以包括: 检测装置 536 , 用 于每隔预定时间段校验保护路径的告警状态; 通知装置 538 , 用于在每次检 测后, 通知保护控制器检测保护路径的告警状态; 处理装置 540 , 用于在网 络管理***和保护控制器的检测结果不一致时, 产生告警状态不一致提示事 件, 在网络管理***和保护控制器的检测结果一致时, 记录保护路径的告警 状态,并根据检测结果确定能够执行保护倒换的保护路径;则保护控制器 50, 还用于在接收到通知装置发送的通知后, 检测保护路径的告警状态。 在优选实施过程中, 检测装置 536、 通知装置 538、 处理装置 540可以 组成网络管理***的保护路径检测子***, 该保护路径检测子***的工作方 式可以参见图 4中描述。 通过上述处理, 网络管理***与保护控制器实时监测保护组中控制器单 板以及业务单板的状态, 保证控制器单板的运行状态与单板状态一致, 确定 能够执行保护倒换的保护路径,通过该方案可以进一步提高保护倒换成功率。 上述***中各装置相互结合的工作方式具体可以参见图 2 至图 4 的描 述, 此处不再赘述。 综上所述, 通过本发明的上述实施例, 提供的实现保护组保护倒换的方 案, 实时地监测保护组中控制器单板以及业务单板的状态, 可以保证控制器 单板的运行状态与单板状态一致; 同时, 当保护倒换发生时, 能够判断出当 前哪些保护组应该发生倒换并检测保护组倒换状态是否正常, 达到了自动检 测保护组倒换状态的效果。 因而能够保证保护倒换的正确发生, 提高保护组 保护倒换的成功率, 并能够有效的减少运维人员的维护作业时间。 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。
