Description

一种分布式设备中大规模OAM检测系统及方法 技术领域
本发明涉及分布式设备领域，具体来讲涉及一种分布式设备中大规模OAM检测系统及方法。
背景技术
IPRAN(Internet Protocol Radio Access Network，无线接入网IP化)技术是对于无线业务回传、大客户业务接入的应用场景而产生的一种核心网实现技术。
在一个分布式设备中，为了检测网络业务的通断情况，需要应用到大规格的OAM(Operation Administration and Maintenance，操作维护管理)资源。传统的实现方法是在每块线卡上设置OAM芯片来进行OAM的检测，但由于每块线卡对资源总规格有限制，往往分配给OAM芯片的资源规格较少，难以实现OAM大规格的应用。而且每块线卡都具有OAM芯片，但业务会分到某块线卡上，由于每块线卡的OAM处理能力有限，很难实现多块线卡上的业务的处理均衡，产生分到办卡上的业务不能完全进行OAM处理，而其他线卡OAM芯片闲置的现象，造成业务不能与OAM处理匹配，整体处理能力不高。另外，当业务所在线卡出现切换时，对业务的处理也会切换到新线卡的OAM芯片上，进而造成OAM出现不稳态的现象。
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分布式设备中大规模OAM检测系统及方法，提高整体设备的OAM处理能 力，提高OAM稳定性。
为达到以上目的，本发明采取一种分布式设备中大规模OAM检测系统，包括交换板卡、多块业务线卡和至少一块OAM板卡，交换板卡用于处理OAM板卡和多块业务线卡之间的OAM报文的交换；每块业务线卡用于处理交换板卡和线路之间的OAM报文的交换；每块OAM板卡包含多个OAM处理单元和一个交换机SW，SW用于交换OAM处理单元和中间交换板卡之间的OAM报文，OAM处理单元下行方向用于在OAM报文前增加下一跳信息并通过SW发送至交换板卡，上行方向用于将来自交换板卡的OAM报文进行OAM处理。
在上述技术方案的基础上，所述OAM板卡为两块，一块为主用OAM板卡，一块为备用OAM板卡，主用OAM板卡用于维护OAM工作状态，备用OAM板卡用于维持与主用板卡相同的工作状态。
在上述技术方案的基础上，所述交换板卡在上行方向用于将OAM报文分别发送给主用OAM板卡和OAM板卡，下行方向用于接收主用OAM板卡发来的OAM报文。
在上述技术方案的基础上，所述OAM板卡为多块时，均为主用OAM板卡，或者部分为主用OAM板卡、部分为备用OAM板卡。
在上述技术方案的基础上，所述OAM板卡还包括一个自动保护倒换APS模块，用于接收OAM板卡检测到的业务工作状态，实现对业务保护状态的维护。
在上述技术方案的基础上，所述APS模块还用于在业务工作路径故障时，接收OAM模块触发的中断信号，并决策当前业务的工作路径。
本发明还提供一种分布式设备中大规模OAM检测方法，包括步 骤：
下行方向，OAM板卡中OAM处理模块在OAM报文的前端增加下一跳信息的报文头，并通过SW发给交换板卡，交换板卡将OAM报文发送到下一跳信息对应的业务线卡上，业务线卡封装报文头后发送到线路上；
上行方向，业务板卡由线路上接收到OAM报文，通过交换板卡转发给SW，SW将OAM报文转发给对应的OAM处理单元，OAM处理单元对OAM报文进行OAM处理。
在上述技术方案的基础上，OAM板卡有两块，一块为主用OAM板卡，一块为备用OAM板卡；下行方向，中间板卡只接收主用OAM板卡发来的OAM报文；上行方向，中间板卡将收到的OAM报文分别发送给主用OAM板卡和OAM板卡。
在上述技术方案的基础上，OAM板卡上集成一个APS模块，OAM处理单元将检测到的业务工作状态发给APS模块，APS确定业务工作在线路的主用路径或备用路径。
在上述技术方案的基础上，当OAM处理单元检测到业务工作路径故障时，触发一个中断信号给APS模块，APS模块执行保护状态处理逻辑，并决策当前业务的工作路径。
本发明的有益效果在于：
1、通过将多个OAM处理单元集成在一块OAM板卡上，经由交换板卡与业务线卡之间传递OAM报文，避免了多块线卡上业务处理不均衡，能够大幅提高整机设备的OAM处理规格和能力；按照不同需求在OAM板卡上设置不同数量的OAM处理单元，从而降低整机的生产成本。
2、在业务出口切换时，不会对OAM处理模块带来影响，提高 OAM处理的稳定性；对用户隔离其具体实现方法，在用户感知度不大的情况能够大幅提高其性能。
3、布置一块与主用OAM板卡互为保护的备用OAM板卡，以实现对OAM管理资源的保护，实现了在分布式设备中大规模OAM的应用。
4、通过设置APS模块，实现业务路径自动保护倒换，进一步提高整机系统的高可靠性。

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。
如图1所示，为第一实施例分布式设备中大规模OAM检测系统，包括交换板卡、多块业务线卡和一块OAM板卡，交换板卡用于处理OAM板卡和多块业务线卡之间的OAM报文的交换，每块业务线卡用于处理交换板卡和线路之间的OAM报文的交换。OAM板卡包含多个OAM处理单元和一个SW(switch交换机)，SW用于交换OAM处理单元和中间交换板卡之间的OAM报文；OAM处理单元在下行方向，用于在OAM报文前增加下一跳信息并通过SW发送至交换板卡；OAM处理单元在上行方向，用于将来自交换板卡的OAM报文进行OAM处理。
优选的，如图2所示，OAM板卡还包括一个APS(Automatic Protection Switching，自动保护倒换)模块，分别与OAM处理单元连接，用于接收OAM板卡检测到的业务工作状态，实现对业务保护状态的维护；APS模块还用于在业务工作路径故障时，接收OAM模块触发的中断信号，并决策当前业务的工作路径。
本实施例分布式设备中大规模OAM检测系统，具体包括以下步骤：
下行方向，OAM板卡的OAM处理模块在OAM报文的前端增加一个报文头，报文头内封装下一跳信息，OAM报文通过SW发给交换板卡，经由交换板卡将OAM报文发送到下一跳信息对应的业务线卡上，业务线卡封装报文头后发送到对应线路上。
上行方向，业务板卡由线路上接收到报文，识别出OAM报文和OAM条目ID，通过交换板卡转发给SW，SW将OAM报文转发给OAM条目ID对应的OAM处理单元，OAM处理单元对OAM报文进行后续OAM处理。
优选的，如图2所示，如果OAM板卡上集成了APS模块，OAM处理单元会将检测到的业务工作状态发给APS模块，APS确定业务工作在线路上的主用路径或备用路径，实现对业务保护的维护。当OAM处理单元检测到业务工作路径故障时，触发一个中断信号给APS模块，APS模块执行保护状态处理逻辑，并决策当前业务的工作路径。
如图3所示，为第二实施例分布式设备中大规模OAM检测系统，与第一实施例大致相同，不同之处在于，OAM板卡为两块，一块为主用OAM板卡，一块为备用OAM板卡。主用OAM板卡用于维护OAM工作状态，备用OAM板卡用于维持与主用板卡相同的工作状 态。交换板卡在上行方向，用于将OAM报文分别发送给主用OAM板卡和OAM板卡；交换板卡在下行方向，用于接收主用OAM板卡发来的OAM报文，正常情况下，并不接收备用OAM板卡发来的OAM报文。优选的，如图2所示，主用OAM板卡和备用OAM板卡中都可以集成APS模块，APS模块的作用与第一实施例相同，此处不再赘述。
本实施例分布式设备中大规模OAM检测方法，与第一实施例不同之处在于，在OAM报文的接收(上行方向)和发送(下行方向)，中间交换板卡实现并发选收功能，具体为：下行方向，主用OAM板卡和备用OAM板卡，都会在OAM报文的前端增加一个封装下一跳信息的报文头，然后发送给交换板卡，交换板卡接收只用OAM板卡发来的OAM报文，并将OAM报文发送到对应的业务线卡上(即下一跳信息对应的业务线卡)，业务线卡封装报文头后发送到对应线路上。上行方向，业务板卡由线路上接收到报文，识别出的OAM报文通过交换板卡分别发送给主用OAM板卡和备用OAM板卡，主用OAM板卡和备用OAM板卡内部对收到的OAM文件处理相同。
本发明的OAM板卡可以为多个，并且可以根据不同的实际使用情况来进行配置。当有多个OAM板卡时，可以都是主用OAM板卡；也可以设置一个备用OAM板卡，其余的都是主用OAM板卡；或者配置部分主用OAM板卡和部分备用OAM板卡；但是无论是如何配置，主用OAM板卡和备用OAM板卡的内部结构和作用均与上述实施例中相同，此处不再赘述。
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。
