Description

一种POTN业务管理的方法 技术领域
本发明涉及POTN应用领域，具体涉及一种POTN业务管理的方法。
背景技术
OTN(Optical Transport Network，光传送网)设备用于IP业务的超长距离、超大带宽传输，可以为大量的2.5Gbps、10Gbps、40Gbps和100Gbps等大颗粒业务提供传输通道，而难以对较小颗粒业务进行处理。而PTN(Package Transport Network，分组传送网)设备多用于小颗粒IP业务的灵活接入、以及业务汇聚，但是，无法传送大颗粒业务。
当前，运营商基于业务需要长距离传输、以及IP业务的剧增的考虑，需要将设备功能耦合，鉴于OTN和PTN各自的优势，OTN设备和PTN设备功能耦合应用较为广泛。
传统的OTN业务主要的业务模型比较简单，多个业务之间映射关系简单，业务模型中所有业务顺次排列，且多个有映射关系的业务排列在一起，在需要变更其中一个业务时，只需前后查找所有与该业务相关的业务，并变更该业务以及与该业务相关的所有业务即可，由于映射关系简单，查找方便，业务调度难度不高。
但是，引入PTN之后，PTN和OTN业务混合，业务类型复杂，多个业务之间映射关系变得非常复杂，业务层级较多，现有的顺次调度方法已难以适用，需要开发一种新的业务管理方法来有效管理 POTN复杂业务。
发明内容
针对现有技术中存在的缺陷，本发明的目的在于提供一种POTN业务管理的方法，可有效管理复杂的业务类型，业务调度方便。
为达到以上目的，本发明采取的技术方案是：
一种POTN业务管理的方法，包括如下步骤：
根据板卡应用场景，建立树结构业务模型；
根据光传送网OTN和分组传送网PTN通信协议配置所述业务模型中每个节点的业务信息，确定板卡的业务终点、与所述业务终点对应的至少一业务起点、以及所述业务起点到业务终点的映射关系；
将所述业务模型的叶子节点配置业务起点信息，所述业务模型的根节点配置业务终点信息，并根据所述业务起点到业务终点的映射关系配置所述业务起点到业务终点的路径。
在上述技术方案的基础上，当板卡用于转发业务时，所述业务模型为对等模型，所述业务模型由一个根节点和一个叶子节点组成，板卡有一个业务终点和一个与所述业务终点对应的业务起点。
在上述技术方案的基础上，当板卡用于汇聚业务时，所述业务模型为一级映射模型，所述业务模型由一个根节点和多个叶子节点组成，板卡有一个业务终点和与所述业务终点对应的多个业务起点。
在上述技术方案的基础上，当板卡用作线卡时，所述业务模型为多级映射模型，所述业务模型包括一个根节点、多个中间节点和多个叶子节点，板卡有一个业务终点、与所述业务终点对应的多个业务起点、以及所述业务起点到业务终点的多级映射关系，根据所述业务起点到业务终点的多级映射关系配置相应数量的中间节点。
在上述技术方案的基础上，还包括步骤：创建轮询任务，所述轮 询任务与业务主芯片交互，所述轮询任务定时采集并存储已配置节点的业务信息，并上报给上层交互接口。
在上述技术方案的基础上，所述业务信息包括业务类型、性能信息、告警信息、状态信息或保护设置开关。
在上述技术方案的基础上，所述业务起点有序排列，并根据所述业务起点的排列顺序确定相应所述叶子节点在所述业务模型的位置。
在上述技术方案的基础上，当需要删除叶子节点的业务信息时，删除所述业务模型中相应的叶子节点。
在上述技术方案的基础上，当需要删除根节点的业务信息时，删除所述根节点所在业务模型的所有节点。
在上述技术方案的基础上，当需要删除中间节点的业务信息时，删除所述中间节点对应的所有叶子节点、以及所述叶子节点到中间节点多级映射的所有节点。
与现有技术相比，本发明的优点在于：本发明的POTN业务管理的方法采用树结构业务模型，并配置每个节点的业务信息，管理所有业务信息，在需要变更其中一个业务时，只需查找到该业务所在的节点位置，变更与该节点相关的子节点即可，查找方便，可有效管理复杂的业务类型，业务调度方便。
附图说明
图1为本发明实施例中一种POTN业务管理的方法的流程图；
图2为本发明实施例中对等模型的结构示意图；
图3为本发明实施例中一级映射模型的结构示意图；
图4为本发明实施例中多级映射模型的结构示意图。
具体实施方式
以下结合附图及实施例对本发明作进一步详细说明。
参见图1所示，本发明实施例提供一种POTN业务管理的方法，包括如下步骤：
S1：根据板卡应用场景，建立树结构业务模型；
S2：根据光传送网OTN和分组传送网PTN通信协议配置业务模型中每个节点的业务信息，确定板卡的业务终点、与业务终点对应的至少一业务起点、以及业务起点到业务终点的映射关系；
S3：将业务模型的叶子节点配置业务起点信息，业务模型的根节点配置业务终点信息，并根据业务起点到业务终点的映射关系配置业务起点到业务终点的路径；
S4：创建轮询任务，轮询任务与业务主芯片交互，轮询任务定时采集并存储已配置节点的业务信息，并上报给上层交互接口。
本发明实施例中，每条业务起点到业务终点的路径形成一可供双向传输业务的业务传输通道，业务信息包括业务类型、性能信息、告警信息、状态信息和保护设置开关等，OTN和PTN的通信协议包括G.798、G.709、MPLS-TP等。
业务起点有序排列，并根据业务起点的排列顺序确定相应叶子节点在业务模型的位置。根据业务起点的时隙信息，按照时间的先后顺序排列所有业务起点，并将相应叶子节点在业务模型中从左到右排列。
参见图2所示，当板卡用于转发业务时，业务模型为对等模型，业务模型由一个根节点和一个叶子节点组成。板卡具有一个输出端口和一个输入端口，将输入端口作为叶子节点，输出端口作为根节点。如100Gbps速率的光转发盘，根节点配置业务信息的业务类型为OTU4，叶子节点配置业务信息的业务类型为100GE。
参见图3所示，当板卡用于汇聚业务时，业务模型为一级映射模 型，业务模型由一个根节点和多个叶子节点组成。根据叶子节点业务颗粒在其高阶颗粒根节点中占用的时隙信息，有序排列所有叶子节点，且叶子节点的业务颗粒大小根据板卡的设计，所有叶子节点的业务颗粒大小之和不超过根节点的颗粒大小。如10路10*10Gbps的汇聚盘，根节点配置业务信息的业务类型为OTU4，根节点的业务颗粒大小为10*10Gbps，叶子节点的业务颗粒大小均为10Gbps，叶子节点配置业务信息的业务类型可以为10GE、OC192、OTU2、OTU2E、FC800、FC1200等。
参见图4所示，当板卡用作线卡时，业务模型为多级映射模型，业务模型包括一个根节点、多个中间节点和多个叶子节点。根据叶子节点到根节点的多级映射关系，确定业务模型中间节点的数量和位置。该业务模型包括四个叶子节点，四个叶子节点按照占用根节点的时隙信息从左到右依次排列，第一个叶子节点到根节点有三级映射，对应有两个中间节点，第二个叶子节点和第三个叶子节点到根节点均为一级映射，第四个叶子节点到根节点为二级映射，对应有一个中间节点。根节点配置业务信息的业务类型为OTU2，四个叶子节点的业务颗粒大小相同，为10GE或ODU2。
当需要删除叶子节点的业务信息时，删除业务模型中相应的叶子节点；当需要删除根节点的业务信息时，删除根节点所在业务模型的所有节点；当需要删除中间节点的业务信息时，删除中间节点对应的所有叶子节点、以及叶子节点到中间节点多级映射的所有节点。
本发明的原理为：采用树结构业务模型进行POTN业务管理，并配置每个节点的业务信息，管理所有业务信息，在需要变更其中一个业务时，只需查找到该业务所在的节点位置，变更与该节点相关的子节点即可，查找方便，可有效管理复杂的业务类型，业务调度方便。
本发明不局限于上述实施方式，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围之内。本说明书中未作详细描述的内容属于本领域专业技术人员公知的现有技术。
