Description

一种设备单板性能数据上报的方法
技术领域
本发明涉及通讯设备系统监测过程中数据上报的方法，特别涉及一种通讯设备系统监测过程中减少物理量性能数据上报的方法。
背景技术
对于通信设备而言，有很多物理量性能数据需要检测。ITU-T(International Telecommunication Union-Telecommunication StandardizationSector，国际电信联盟-电信标准化部门)Q.822、M.2120对于性能管理规定了15分钟和24小时两种性能采集周期，所采集的数据分别称为历史15分钟性能数据、24小时历史性能数据。以历史15分钟数据采集为例，对于一个WDM(wavelength division multiplexing，波分复用)系统，网元设备中各个单板，每隔15分钟就产生一次15分钟历史性能并上报网管。这样，对于一个80波双向满配置网元来说，需要监测的光源数目为160个，再加上其他配套装置可能有近200个被检测单板，平均每块单板的性能种类为15个，则一天的历史15分钟性能数据量为200×15×(24×(60/15))＝288000条历史性能。估算每条历史性能在数据库中占据128字节，则一个100个上述网元规模网络的网管服务器一天的历史15分钟性能储存量为288000×128×100＝3.4G字节，数据量非常大。
数据量大导致的问题是通讯带宽、CPU处理时间、储存容量等均被占用，通信系统管理效率大大降低。如何解决这个问题？
现有方法是性能屏蔽。被屏蔽的性能将不再上报。但由此带来的问题是，一旦系统出现故障，将无法获取先前的历史性能供故障分析。
因此需要一种设计方案，既能够减少网元物理量性能上报的数据量，又不影响对历史性能的故障诊断、预测的要求。
发明内容
本发明所要解决的技术问题在于提供了一种设备单板性能数据上报的方法，既能够减少网元物理量性能上报的数据量，又不影响对历史性能的故障诊断和预测要求。
为解决上述技术问题，本发明提供了一种设备单板性能数据上报的方法，包括以下步骤：
(1)根据网元设备单板的各项性能数据的正常波动范围，为每项性能数据确定一个“恒性能门限”，超过该门限的数据属于非正常波动；
(2)对网元设备单板的各项性能数据进行采集，获得各项性能数据的当前值；
(3)将所述监测得到的当前值与该性能数据对应的“恒性能门限”值进行比较；
(4)如果所述当前值超越了所述“恒性能门限”，则上报该当前值；如果所述当前值未超越所述“恒性能门限”，则抑制该当前值的上报。
所述步骤(2)，对各项性能数据的采集可以是周期进行的。
“恒性能门限”与性能门限是有区别的，性能门限是性能正常工作的范围，超越其门限的性能是不正常的性能，设备工作很可能处于不正常状态；而“恒性能”门限内的性能均是正常值，是根据统计结果确定的一个正常波动范围内的值，其对于性能趋势分析是没有意义的。显然，性能门限所界定的范围要比“恒性能”门限所界定的范围要宽，超越“恒性能”门限而处于性能门限内的性能数据对于趋势分析才是有意义的。
而本发明也可以进一步根据采集到的当前性能数据与“性能门限”的比较，而确定设备是否处于正常工作状态，并进而报警。这可以结合上述步骤而实现，即：
上述步骤(1)可以进一步包括：根据网元设备单板的各项性能数据的正常工作范围，为每项性能数据确定一个“性能门限”，超过该门限的数据属于非正常工作性能；
上述步骤(3)可以进一步包括：将所述监测得到的当前值与该性能数据对应的“性能门限”值进行比较；
上述步骤(4)可以进一步包括：如果所述当前值超越所述“性能门限”值，则在上报该当前值的同时，上报告警信息。
本发明所述的方法还可以进一步包括：
在网元设备单板中设置一个“恒性能”指示寄存器，该寄存器中的每一个比特位唯一对应一个性能种类；
如果在性能数据上报过程中，一个性能种类的当前数据值被抑制上报，则利用所述寄存器对应的比特位记录该抑制情况。
所述方法还可以进一步包括：
在性能数据上报过程结束后，将所述寄存器内容上报给上层管理系统；
上层管理系统分析所述寄存器内容，如果在所述性能数据上报过程中没有收到的性能种类，在所述寄存器内容中也没有被抑制的记录，则发起性能补充采集命令。
使用本发明方法可以减少监控过程中数据的发送量和CPU负载，节约通讯带宽，降低网元控制器对数据处理能力以及系统对数据储存量的要求，并且有利于监控人员关注有意义的性能数据，提高系统维护效率。

具体实施方式
如图1所示，为根据本发明实施例所述的“恒性能”上报抑制原理图。本发明实施例提出一种“恒性能”上报抑制方法，在单板层通过筛选性能，过滤掉不具备分析价值的性能，不上报给上层管理系统来达到减少数据量的目的。
经过分析，绝大多数上报的物理量性能数据都稳定在一个很细小的正常的范围内波动。此时的性能值属于正常范围，对于性能趋势分析没有价值，此范围内的性能称之为“恒性能”，此正常波动范围称之为“恒性能门限”。“恒性能门限”与性能门限是有区别的。性能门限是性能正常工作的范围，超越门限的性能是不正常的性能，设备工作很可能处于不正常状态，设备将上报性能越限告警。
“恒性能”门限内的性能均是正常值，且对于性能趋势分析没有意义。性能门限所界定的范围要比“恒性能”门限界定的范围要宽。超越“恒性能”门限而处于性能门限内的性能数据对于趋势分析是有意义的。“恒性能”上报抑制机制的具体步骤为：
步骤101，初始时上层管理系统根据需要针对每种物理量对单板设置“恒性能”基准值，并设置一个“恒性能”门限。由于不同单板的物理器件特性存在差异，所以可能需要针对每块单板的设置“恒性能”基准值。
步骤102，管理系统检测时序是否达到采集周期，如果时序到达采集周期进行下一步，否则继续等待。
步骤103，时序到达采集周期，单板生成性能数据。
步骤104，判断物理量性能数据是否在“恒性能”门限内，如果上报的物理量在“恒性能”门限内，认为是恒定性能，不上报此物理量。此为“恒性能”抑制生效。
步骤105，如果上报的物理量超越“恒性能”门限，上报此物理量。
步骤106，判断物理量性能数据是否在性能门限内。
步骤107，如果上报的物理量性能数据超越性能门限，上报越限告警。
如图2所示，为根据本发明实施例所述的“恒性能”性能缺失原因分析原理图。“恒性能”抑制上报带来一个问题：如果上层管理系统性能缺失，是因为“恒性能”不上报导致性能缺少，还是因通讯处理等故障等原因未收到性能？如何区别？本发明实施例是采用“恒性能”上报确认机制来实现区分。首先在检测单板中设置一个“恒性能”指示寄存器。此寄存器中的每一个比特位唯一对应某个性能种类，表示在15分钟性能采集周期中此性能种类是否被“恒性能”抑制了。当单板上报完所有的实际物理量性能后，将此指示寄存器内容上报给上层管理系统。
“恒性能”性能缺失原因分析的具体步骤为：
步骤201，上层管理系统接收到“恒性能”抑制寄存器的内容。
步骤202，管理系统根据接收内容判断物理量性能数据是否发生缺失，如果发生缺失，进行下一步；否则，过程结束。
步骤203，管理系统根据寄存器内容判断缺失内容是否在“恒性能”抑制寄存器中，如果缺失性能种类包含在“恒性能”抑制寄存器内容中，则此性能缺失原因是“恒性能”抑制，属于正常现象，过程结束。
步骤204，如果缺失性能种类不包含在“恒性能”抑制寄存器内容中，则此性能缺失异常，管理系统发起性能补取。
步骤205，管理系统判断重新获取性能是否成功。
步骤206，如果管理系统重新获取性能不成功，则为记录异常。
如图3所示，为根据本发明实施例所述的WDM系统OTU单板输入光功率“恒性能”检测原理图，其中：检测对象为：入光功率；实施对象为：OTU(Optical Transponder Unit，光转发单元)单板；输入无光性能门限为：-17dBm；“恒性能”基准值为：-5.30dBm(注意每块单板的恒性能基准值可能不一样)；恒性能范围为：[-6.30，-4.30]dBm。WDM系统OTU单板输入光功率“恒性能”检测机制的具体步骤为：
步骤301，每隔15分钟采集周期到来。
步骤302，OTU单板自动生成光功率性能数据。
步骤303，判断输入光功率是否超越“恒性能”门限，如果没有，过程结束，等待下一个采集周期到来；如果超越“恒性能”门限，进行下一步。
步骤304，上报输入光功率性能数据给上层管理系统。
步骤305，判断输入光功率性能数据是否超越性能门限，如果没有，过程结束，等待下一个采集周期到来；如果超越性能门限，进行下一步。
步骤306，上报入光越限告警给上层管理系统。
如图4所示，为根据本发明实施例所述的OTU单板15分钟输入光功率性能值的变化趋势24小时全图，本图显示了24小时内的OTU入光功率的变化趋势。其中，X轴表示15分钟性能计数序列。样本总数为24×4＝96个。可以看出，绝大多数样本都稳定在-5.30dBm，只有少数波动。
如图5所示，为根据本发明实施例所述的OTU单板15分钟输入光功率性能值的变化趋势恒性能部分图。本图显示了输入光功率性能值的恒性能变化趋势，是1～38计数区间的局部放大图，在1～32个15分钟内，性能值均在[-6.30，-4.30]，因此均为恒性能，不上报网管，此后超越恒性能门限：
第33个15分钟点时，性能值为-6.30dBm；
第34个15分钟点时，性能值为-7.50dBm；
第35个15分钟点时，性能值为-12.7dBm；
第36个15分钟点时，性能值为-15.9dBm。
33、34、35、36区间突破了恒性能门限，但是未突破性能门限，此性能上报给上层管理系统，记录下来供分析。
如图6所示，为根据本发明实施例所述的OTU单板15分钟输入光功率性能值的变化趋势突变部分图，本图显示了输入光功率性能值的突变趋势：
第37、38、39、40、41、42个15分钟点时，性能值为-19.10dBm；此时突破了性能门限，单板将上报性能值，同时上报越门限告警。
本发明实施例的“恒性能”突破、性能越限的过程是因为施工中手工缓慢插拔入光光纤造成的。在这种情况下，非恒性能样本点只有11个，恒性能抑制机制下上报数据量只有原有数据量的11/96*100％＝11％。
实际工程开通后，恒性能范围内的性能值所占数据量的比例更大。根据工程统计，恒性能量约占总数据量的99.9％。可见，本发明可以大大减少数据量，有较大实践应用价值。
