( 1 ) 资源模型处理模块根据更新的资源状态信息和 /或连接状态信息获 取传送节点内各个传输路径上的资源状态信息;
( 2 ) 资源模型处理模块汇总全部传输路径上的资源状态信息得到总传 送节点资源状态模型;
( 3 ) 资源模型处理模块删除总传送节点资源状态模型中当前业务使用 和预留的资源, 生成可用的传送节点资源状态模型。 在优选实施过程中, 资源模型处理模块接收到单板资源获取模块发送的 更新的资源状态信息时, 根据资源状态信息改变的单板获得单板所在的信号 传输路径,依次遍历路径上的所有单板,按照各种资源信息对应的计算法则, 取所有单板各种可用传送资源的合集。 从而获得该传输路径上的传送节点资 源状态信息。 在具体实施过程中, 上述合集计算并非简单地将所有资源计算出来再取 并集, 而是按照单板的性能和传送节点内部的拓朴结构进行的计算。 例如, 对传输路径上的资源分为最大可用传送资源 (从逻辑上划分) 和 当前可用传送资源, 来表明该节点资源是此条传输路径上最大 (系统逻辑上 的, 即可通过修改设备上的约束参数而获得的) 可使用的传送资源, 以及在 特定条件 (比如在当前约束参数状态) 下的可用传送资源。 又如, 不同的信号有的可以单独传输, 有的必须有依赖关系, 则首先分 别求得所有信号的可用资源, 然后才艮据不同的传送资源(例如, 光信号波长, 电信号时隙等) 间相互的映射关系, 得到传送资源映射表, 指出可用资源及 其逻辑关系。 又如, 不同信号间的依赖关系有时又由设备的设置所设定, 在进行计算 时必须根据设备的设置进行相关的处理。 以下结合图 4所示的示例描述上述优选计算方式。 图 4为才艮据本发明实例的复杂传送节点的内部结构示意图。如图 4所示, 在该传送节点中, 单板性能如下: 光业务单板和光电混合业务单板的上面一侧(线路侧;),传输的是光信号, 一次业务只能使用一种波长, 但可选择的波长分为 1 , 可传输多种波长; 2, 只可传输一种波长。 下面一侧(客户侧), 传输的是电信号, 其中一次业务只 能使用一个时隙。 图中的配置为: 电业务单板和光电混合业务单板的下面一侧(客户侧;),传输的是电信号 一次业务只能使用一个时隙的电信号。 光电混合单板可将不同时隙的电信号接入到一个波长的光信号中进行传 输。 合波单板的 Al、 A2、 A3输入端口都可以在一次业务中输入任意一种波 长, 但合波单板的 A4输入端口上可接入光波长为 λΐ , λ2, λ3 , λ4的信号, 但当前设定为只能允许调谐的特定波长输入, 此时, 调谐的波长为 λ3 , 即当 前只能通过波长为 λ3的信号。 光业务单板 1只能传输光信号, 传输的波长为 λΐ , λ2, λ3。 光电混合业务单板 1能传输光信号和电信号, 但是电信号需转化为光信 号才能进行传输, 其可以传输的光信号只有波长 λΐ , 其可传输的电信号为时隙为 tl的信 号。 电业务单板 1可以传输的电信号为时隙 tl,t2的信号。 电业务单板 2可以传输的电信号为时隙 t2,t3的信号。 光电混合业务单板 2可以传输的光信号为波长 λΐ ; 且可以将 tl和 t3信 号转换为光信号。 光电混合业务单板 3可以传输的光信号为波长 λ3 , λ4; 且可以将 tl , t2 和 t3信号转换为光信号。 合波单板具有将各种不同的波长合成复用波进行传输的功能, 其接入端 口分为 1 , 可在多种波长信号中任意接入一种(如可无条件接收 λΐ , λ2, λ3 , λ4中的任意一种); 2, 可在多种波长信号中一定条件下只能接入其中一种波 长信息号的 (如当端口可接收的信号为 λΐ , λ2, λ3 , λ4, 但当此时该端口 上调谐到接入信号为 λΐ时, 则不能接收 λ2, λ3 , λ4信号; 当此时该端口上 调谐到接入信号为 λ2时, 则不能接收 λΐ , λ3 , λ4信号)。 此外, 因为波长相 同的信号会相互产生千扰, 所以输入到合波单板的不同业务的波长需不相同 (即光业务单板 1上的 λΐ信号不能与光电混合业务单板 1上的 λΐ信号同时 接入合波单板 1上;)。 电交换单板可将电业务单板的任意信号传输到不同的光电混合业务单板 上。 所以, 电业务单板 1和电业务单板 2的电信号可以通过电交换板选择光 电混合业务单板 2和光电混合业务单板 3的任意一个, 将电信号转化为光信 号进行传输。 此外, 相同时隙的信号在电交换单板上会产生千扰, 所以同一 时间, 电交换单板上的电信号的时隙不能相同 (即光电混合业务单板 2上的 t3信号和光电混合业务单板 3上的 t3信号不能同时接入电交换单板 1上;)。 根据上述单板性能和传送节点内部的拓朴结构的计算方式如下:
( 1 ) 在未有任何业务建立的时候, 从客户侧到传送接口 B的最大可使 用的传送资源为波长 λΐ , λ2, λ3 , λ4的信号以及, 时隙为 tl , t2, t3的信号。 但由于合波单板 1的性能限定, A4端口不能使用 λ4波长, 所以 λ4在当前为 不可用资源。 当前可使用的传送资源为波长 λΐ , λ2, λ3的信号以及, 时隙为 tl , t2, t3的信号其中。 光信号没有依赖性, 而电信号依赖于光信号: 时隙 为 tl的信号的可用性依赖于波长 λΐ的信号, 所以时隙为 tl的电信号与波长 为 λΐ , λ3形成两组传送资源映射; 时隙为 t2的信号可以和波长为 λ3组成一 组可用传送资源映射; 时隙为 t3的信号 (电业务单板 2 ) 可以和波长为 λΐ (光电混合业务单板 2 ) 及 λ3 (光电混合业务单板 3 ) 组成共两组可用传送 资源映射。 一共五组可用传送资源映射。
( 2 ) 当光业务单板 1用 λ2建立业务后, 光电混合业务单板 1即成为不 可用单板, λ2波长为不可用资源。此时的最大可使用的传送资源均为波长 λ 1 , λ3 , λ4的信号以及, 时隙为 tl , t2和 t3的信号。 而当前可用的传送资源为 波长为 λΐ , λ3以及, 时隙为 tl , t2和 t3的信号, 其中时隙为 tl的信号可以 和波长为 λΐ的光信号(光电混合业务单板 1和光电混合业务单板 2 )及波长 为 λ3的光信号 (光电混合业务单板 3 ), 组成两组可用传送资源映射; 电业 务单板 1上的时隙为 t2的信号可以和波长为 λ3的光信号 (光电混合业务单 板 3 )组成一组可用传送资源映射; 电业务单板 2上的时隙为 t3的信号可以 接入波长为 λΐ的光信号 (光电混合业务单板 2 ) 及波长为 λ3的光信号 (光 电混合业务单板 3 ), 共组成两组可用传送资源映射。一共五个可用传送资源 映射。
( 3 ) 当用电业务单板 1使用时隙为 tl的电信号, 经过光电混合业务单 板 3 , 使用波长 λ3的光信号输出。 则此时最大可使用的传送资源为 λΐ的光 信号 (光电混合业务单板 1和光电混合业务单板 2 ) 以及, 时隙为 tl , t2和 t3的信号。 其中, 光电混合业务单板 1的时隙为 tl的信号可接入到其上的波 长为 λΐ的信号上进行传输, 因为电业务单板 1虽然使用 tl的电信号, 但是 是接入到波长为 λ3的光信号上, 这两个光信号波长不同, 属于不同的载波, 所以可以允许两个不同的信号同时使用时隙为 tl的电信号。 此时, 时隙为 tl 的电信号与波长为 λΐ形成一组传送资源映射; 电业务单板 2上的时隙为 t2 的电信号可用光电混合单板 2上的波长为 λΐ的光信号, 以及光电混合单板 3 上的 λ3 , 共形成两组可用传送资源映射。 电业务单板 2上的时隙为 t3的电 信号可接入光电混合单板 2上的波长为 λ3的光信号及光电混合单板 2上的波 长为 λΐ的光信号, 共形成两组可用传送资源映射。 一共四个可用传送资源映 射。 资源模型处理模块接收到内部连接获取模块发送的更新的连接状态信息 时, 居该内部连接获得所在的信号传输路径,依次遍历路径上的所有单板, 按照各种资源信息对应的计算方式, 取所有单板各种可用传送资源的合集。 从而获得该传输路径上的传送节点资源状态信息。 资源模型处理模块以节点内传送路径的信号输入单板为路径逻辑起点, 以传送路径的信号输出单板为路径逻辑终点构造传送节点内传输路径集合, 并且在每条传输路径的附属信息里指明传输路径的类型, 传输路径上的信号 类型, 及总传送资源集合。 资源模型处理模块向业务资源管理查询当前业务所使用的资源以及预留 的资源, 并从总资源状态模型中将其删除, 获得上述可用的传送节点资源状 态模型。 优选地, 在执行上述步骤 S 106之后, 还可以包括以下处理:
( 1 ) 资源模型处理模块按照性能属性划分可用的传送节点资源状态模 型所管理的传送节点资源状态信息的资源性能; 其中, 上述资源性能指的是单板的性能属性, 例如, 输出光的功率, 光 的非线性, 色散情况、 信号的时隙, 信号的衰减性能, 误码率门限等。
( 2 ) 资源模型处理模块釆用与划分后的资源性能对应的调节方案调节 资源性能。 以下结合实施例详细描述上述优选实施过程。 在优选实施过程中, 上述 过程可以进一步包括以下处理: 步骤 1 : 当系统启动或者传送节点内各单板的工作状态及性能信息发生 改变时, 开始进行节点内性能信息的处理。 步骤 2: 按照性能属性进行划分, 例如故障告警, 信号损伤等。 由此可见,可以实现对节点内管理组件处于可用和不可用变化时的检测, 当管理组件的特征参数改变时,也可以触发资源模型状态自动检测处理流程, 从而实现实时更新节点内部资源模型的状态。 除了资源信息外, 还可以检测 管理组件的性能信息和告警信息,从而可以获得和处理组件的工作状态信息。 步骤 3: 在不同的资源性能种类处理表中根据资源性能选取对应的处理 方案。 其中故障告警包括无光, 功率小于门限, 误码率高于门限等; 信号损 伤类包括光色散, 偏振, PDM时延等。 步骤 4: 校验性能修改循环计数器的值, 如果超过规定循环次数则转到 步骤 6。 设置循环计数器的值, 是为了避免运行死循环。 步骤 5: 以系统设定的性能值为执行处理方案, 对单板配置参数进行修 改。 通过上述处理, 能够实现管理组件处于告警或不满足正常使用状态时关 键参数的自动调整以及自动调整方法的自动获取。 步骤 6: 重新执行步骤 1的处理, 获得单板配置参数修改后的新的资源 性能, 并一直运行到步骤 2。 步骤 7: 处理故障告警的^ ί'爹改结果。 如果故障无法处理并影响单板的正 常使用,则在可用的传送节点资源状态模型中将此信号传输路径标记为故障。 并显示具体的故障原因。 如果存在故障但不影响单板的正常使用, 则在该资 源状态模型中将此信号传输路径标记为异常, 并显示具体的异常原因。 如果 故障告警修改后在正常工作范围内, 则显示本条信号传输路径, 且标记为正 常。 通过上述处理, 资源模型处理模块能够完成自动检测传送节点内的资源 状态, 获得资源状态模型, 并根据系统内各单板的性能和告警, 自动的进行 调节, 最终实现满足系统正确传输信号所需的性能要求, 并将可用传输的资 源模型上报。 优选地,在资源模型处理模块调节资源性能之后,还可以包括以下处理: 资源模型处理模块将可用的传送节点资源状态模型所管理的传送节点资源状 态信息向链路泛宏。 通过上述处理, 不仅可以实现单节点的资源状态模型, 并且还可以实现 多节点网络内的传送节点资源状态信息的检测和更新。 以下结合图 5描述上述传送节点资源状态信息的优选处理方式。 图 5为才艮据本发明优选实施例的传送节点资源状态信息的处理方法的流 程图。 如图 5所示, 该过程主要包括以下处理: 步骤 S502: 资源模型处理模块接收到传送节点内部资源状态信息改变的 消息;

第三获取单元 642 , 设置为汇总全部 传输路径上的资源状态信息得到总传送节点资源状态模型; 生成单元 644 , 设置为删除总传送节点资源状态模型中当前业务使用和预留的资源, 生成可 用的传送节点资源状态模型。 优选地, 如图 7所示, 资源模型处理模块 64可以进一步包括: 划分单 元 646 , 设置为按照性能属性划分可用的传送节点资源状态模型所管理的传 送节点资源状态信息的资源性能; 调节单元 648 , 设置为釆用与划分后的资 源性能对应的调节方案调节资源性能。 优选地, 如图 7所示, 上述装置还可以包括: 泛宏模块 66 , 设置为将可 用的传送节点资源状态模型所管理的传送节点资源状态信息向链路泛宏。 上述各模块及各模块中各单元相互结合的优选实施方式具体可以参见图 5 , 此处不再赘述。 以下结合三个示例进一步描述上述优选实施方式。 实例 1 : 下面结合图 8、 图 9、 图 2和图 5描述传送节点资源状态信息的处理过 程, 主要包括以下处理: 步骤 1 : 居节点内部配置需求, 配置好硬件工作环境, 例如, 配置单 板以及单板之间的光纤连接。 步骤 2: 给系统上电, 启动系统软件和各个单板软件, 此时系统内部单 板连接如图 8所示, 此时单板资源获取模块获得光业务单板 1与光业务单板 2可以同时接收和发射波长为 λΐ和 λ2的光波; 波长选择单板 1和波长选择 单板 2可以通过的波长均为 λΐ ~ λ10。 此外, 内部连接获取模块获得 6条连 接, 如图 8中的连接 1 ~连接 6。 并且得出四条信号传输路径, 分别为: ( 1 ) Α处信号输入单板经业务单板 1到客户侧; ( 2 ) A处信号输入单板经业务单 板 2到客户侧; (3 ) 由客户侧经由业务单板 1到 B处信号输出单板; (4 ) 由 客户侧经由业务单板 2到 B处信号输出单板。 步骤 3: 资源模型处理模块根据单板资源获取模块和内部连接获取模块 获得四条信号传输路径上的资源模型信息: ( 1 ) 由 A处经由业务单板 1到客 户侧的输入信号可以使用的光波长为 λΐ和 λ2; ( 2 ) 由 Α处经由业务单板 2 到客户侧的输入信号可以使用的光波长为 λΐ和 λ2; ( 3 ) 由客户侧经业务单 板 1到 Β处的输出信号可以使用的光波长为 λΐ和 λ2; ( 4 ) 由客户侧经业务 单板 2到 Β处的输出信号可以使用的光波长为 λΐ和 λ2。 并最终得出由 Α处 信号输入单板到客户侧的可用波长为 2条, 分别为 λΐ和 λ2; 由客户侧到 Β 处信号输出单板的可用波长为 2条, 分别为 λΐ和 λ2。 步骤 4: 插入一个新的光业务单板 3 , 设置为只有一个可用波长 λ3的不 可调谐状态, 并使其正常工作。 此时, 系统内部单板连接更改为图 9所描述 的情况, 单板资源获取模块获得此业务单板 3的可用波长 λ3。 并将此传送资 源信息发送到资源模型处理模块。 步骤 5: 由于此业务单板 3并未与节点内的其他单板进行连接, 所以可 用的传送节点资源状态模型未改变。 步骤 6: 经过性能及故障检查, 发现传输路径上的各单板的性能参数符 合系统正常传输的需求, 因此未触发性能和故障解决处理。 步骤 7: 因为可用的传送节点资源状态模型管理传送节点资源状态信息 未发生改变, 所以不触发链路泛宏处理。 实例 2: 在实例 1结束后, 下面结合图 10、 图 3和图 5说明新增内部连接时传送 节点资源状态信息的处理过程, 主要包括以下处理: 步骤 1: 用两条光纤分别连接分波单板与此业务单板 3以及合波单板与 此业务单板 3。 步骤 2: 内部连接获取模块获取到步骤 1的两条新的光纤连接, 并由此 计算出两条新的信号传输路径: ( 1 ) Α处信号输入单板- >波长选择单板 1-> 业务单板 3->客户侧; ( 2 )客户侧 ->业务单板 3->波长选择单板 2-> B处信号 输出单板。 然后将此两条信号传输路径发送给资源模型管理。 步骤 3: 资源模型处理模块根据实施例 1中单板资源获取模块获取的业 务单板 3的可用波长信息以及内部连接获取模块获得信号传输路径。 获得两 条新的信号传输路径上可以使用的波长为 λ3 , 并且经过与实施例 1中步骤 2 的四条信号传输路径故合集, 得出从 A处到客户侧的可用波长为 3个, 分别 是 λΐ , λ2和 λ3; 从客户侧到 Β处的可用波长为 3个, 分别是 λΐ , λ2和 λ3。 步骤 4: 经过性能及故障检查, 发现传输路径上的各单板的性能参数符 合系统正常传输的需求, 因此未触发性能和故障解决处理。 步骤 5: 由于传送节点内可用的传送节点资源状态模型所管理的传送节 点资源状态信息发生了改变, 则将此传送节点资源状态信息向链路泛宏, 通 知其他节点。 实例 3: 在实例 2结束后, 下面结合图 10、 图 2、 图 3和图 5说明单板传送资源 改变时传送节点资源状态信息的处理过程, 主要包括以下处理: 步骤 1 : 4爹改业务单板 3的波长调谐属性, 使其成为波长可调谐单板, 可调 i皆的波长为 λ4和 λ5。 步骤 2: 单板资源获取模块获得业务单板 3的可用波长为 λ4和 λ5。单板 资源获取模块本地存储信息并发送给资源模型处理模块。 步骤 3: 资源模型处理模块根据单板资源获取模块获得业务单板 3的可 用波长信息发生的变化。 在业务单板 3所属的路径进行计算。 4爹改之前业务 单板 3相关路径上的资源状态, 修改为: ( 1 ) 由 Α处经由业务单板 3到客户 侧的输入信号可以使用的光波长为 λ3和 λ4; ( 2 ) 由客户侧经业务单板 3到 Β处的输出信号可以使用的光波长为 λ3和 λ4。 然后再与节点内的其他信号 传输路径做合集, 并最终得出由 Α处信号输入单板到客户侧的可用波长为 4 条, 分别为 λΐ , λ2, λ3和 λ4; 由客户侧到 Β处信号输出单板的可用波长为 4条, 分另' J为 λΐ , λ2, λ3和 λ4。 步骤 4: 资源模型处理模块检测各单板的性能参数, 发现业务单板 3的 输出光功率小于正常功率的额定值, 触发性能及故障解决处理机制。 然后从 上述机制中获得解决方法为提高单板 3的输出端口的输出功率。 当单板 3的 资源信息发生改变后, 重新生成新的资源模型。 再经检测, 发现该节点的链 路上各单板的性能参数符合正常传输信号的参数要求, 从此得到实际可用的 传送节点资源状态模型。 步骤 5 : 由于传送节点内可用的传送节点资源状态模型所管理的传送节 点资源状态信息发生了改变, 则将此传送节点资源状态信息向链路泛宏, 通 知其他节点。 综上所述, 借助本发明提供的上述实施例, 能够自动的检测传送节点内 部传送资源的变化,并才艮据新的传送资源条件生成新的传送解节点资源模型, 并且当性能不符合正确传输要求的情况下, 可以触发参数自动调节机制, 使 单板的性能值符合系统正常传输信号所需满足的参数要求。 通过上述处理, 可以实现对系统的自动化智能化管理, 从而大大提高整个系统的性能和鲁棒 性。 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。
