Description

网管系统中时间信息的管理方法和装置 技术领域
本发明涉及网络管理领域，尤其涉及一种网管系统中时间信息的管理方法和装置。
背景技术
告警管理是网管的基础功能，告警的产生时间又是告警信息的重要组成部分。告警的产生时间依赖于网元时间，一般说来，这个时间就是告警发生时的网元时间。如果网元的时间有所偏差，告警的时间也会随之偏差，这会对用户造成很大的影响。网元的时间如此重要，所以一般要求网管的操作人员定时对网元进行校时，也有的网管提供了定时校时功能——网管会定时给网元下发校时命令。不过即使网元的时间得到了纠正，在偏差时间内上报的告警中的时间也已经发生了偏移，这段时间偏移了的告警都有可能误导用户。

附图说明
此处所说明的附图用来提供对本发明的进一步理解，构成本申请的一部分，本发明的示意性实施例及其说明用于解释本发明，并不构成对本发明的不当限定。在附图中：
图1为本发明实施例提供的网管系统中时间信息的管理方法的流程图；
图2是本发明实施例中自动检查网管与网元时间偏差并形成修正规则的流程图；
图3是本发明实施例中对上报的告警进行时间修正的流程图；
图4为本发明实施例提供的网管系统中时间信息的管理装置的结构图。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图及具体实施例对本发明作进一步的详细描述。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
图1为本发明实施例提供的网管系统中时间信息的管理方法的流程图。图1所示方法包括：
步骤101、网管单元获取网元和网管单元上时间的偏差值；
步骤102、在接收到所述网元的管理信息时，所述网管单元利用所述时间的偏差值对所述网元的管理信息中的时间信息进行修正，得到修正后的网元的管理信息。
本发明提供的方法实施例，利用网管和网元的时间偏差，对网元的管理信息中的时间进行修正，使网管呈现出来的当前管理信息更为准确，达到提高网管信息中记录的时间信息的准确度的目的。
下面对本发明提供的方法作进一步说明：
所述网管单元获取网元和网管单元上时间的偏差值，包括：
按照预先设置的时间间隔，获取所述网元当前的时间和所述网管单元当前的时间；
计算所述网元当前的时间和所述网管单元当前的时间的差值，得到网元和网管单元上时间的偏差值。
其中，所述时间间隔之间可以相同，也可以不同，在实际应用中，时间间隔的控制可以通过定时器来管理。
其中，网元当前的时间可以通过网管单元通过与各个网元发起轮询操作来获取。
其中，所述网管单元获取网元和网管单元上时间的偏差值之后，所述方法还包括：
判断所述时间的偏差值是否大于预先设置的时间阈值；
如果所述时间的偏差值大于所述时间阈值，则输出所述网元的时间发生偏差的告警信息。
通过将得到的时间偏差值与时间阈值进行比较，在时间的偏差值大于时间阈值时，通过输出时间发生偏差的告警信息提示用户，方便用户获知网元的时间信息的运行状态，为及时修正时间提供了操作依据。
其中，所述在得到修正后的管理信息之后，所述方法还包括：
输出所述修正后的网元的管理信息。
通过将修正后的网元的管理信息，可以方便外部获知网元的运行信息，且由于时间信息是经过修正的，使得外部更加准确地获知了管理信息中记录的事件发生的时间。
其中，所述网元的管理信息包括所述网元的告警信息。
在实际应用中，由于在偏差时间的情况下，上报的告警信息都有可能误导用户设备，因此，在管理信息为告警信息时，对告警信息中时间进行修正更为重要。
由上可以看出，本发明提供的方法具具体包括：
步骤一：为每个网元分配一个定时器，并启动。
步骤二：某个网元的定时器时间间隔来到时，查询网元当前的时间。
步骤三：获取网管的当前时间，将此时间与步骤二中查询到的网元时间做比较，得到一个差值。
步骤四：把步骤三中的得到的差值与门限值做比较，如果越限则上报网元时间偏差告警，以提示用户，并执行步骤五，否则执行步骤二，等待下一个定时间隔。
步骤五：将步骤三中得到的时间以及相应差值记录到下面这样的时间规则表1中。在步骤二到步骤五反复定时执行之后，会形成一个时间规则表。
时间节点1 节点1修正规则
时间节点2 节点2修正规则
时间节点3 节点3修正规则
…… ……
时间节点n 节点n修正规则
时间规则表1
步骤五：在接收到一条新的管理信息之后，需要检查管理信息对应的发生时间，比对时间规则表，如果与某一条时间规则相符，则进行步骤六。
步骤六：对符合时间规则的发生时间按照表中规则进行修正。
下面以应用实例对本发明提供的方法作进一步说明：
下面以客户端/服务器Client/Server方式的网管系统进行说明：
网管单元为用户提供网元与网管时间偏差的门限值配置界面，并提供默认值。之后时间偏差告警的判断以此门限值为准，设此门限为M。初始化一个Map结构RuleMap，<网元ID，网元修正规则表>，其key为网元ID，value为此网元的时间修正规则表，不妨也定位为一个Map结构，<网元时间，修正规则>第二个Map结构的key为检测到的偏差了的网元时间，value里存放规则字符串。
图2是本发明实施例中自动检查网管与网元时间偏差并形成修正规则的流程图；图2所示流程包括：
步骤一：启动一个定时器线程，设定定时器时间间隔为10秒。
步骤二：每个10秒定时间隔到来时，轮询网元，查询网元上的当前时间信息，假设某个网元查询的结果为T1。
步骤三：获取此时的网管系统时间，设为T1'。将网管系统时间与网元时间做差，结果设为D，即D＝T1'–T1。
步骤四：比较步骤三中得到的差值D和此前设置好的门限值M。如果D的绝对值大于M，则上报网元时间偏差告警以提示用户，并执行步骤五。
步骤五：根据步骤四中得到的数据，计算得到一个名值对<网元时间，偏差时间修正规则>，并作为一条规则插入到这个网元的网元修改规则表中。
举一个例子，比如步骤二中的网元时间T1为2015/09/12 15:30:10,步骤三中获取到的网管系统时间T1'为2015/09/12 15:30:13，那么步骤四中得到的差值D则为3秒。假设3s大于最初设定的偏移告警门限值，则在步骤五中得到的规则名值对为<2015/09/12 15:30:10,“+3”>，以表示网元在2015/09/12 15:30:10时，上报的相关时间信息需要做增加3秒的修正。
经过一系列的定时间隔之后，每个网元都将形成自己的修正规则表，例如上述举例网元的时间修正规则表可能是这样的：
2015/9/12 15:46:10 +3
2015/9/12 15:46:20 -1
2015/9/12 15:46:30 +2
…… ……
最近一次时间 最近一次时间规则
网元的时间修正规则表
图3是本发明实施例中对上报的告警进行时间修正的流程图；图3说是告警上报过程中进行时间修正的步骤：
步骤一：接收到告警上报之后，取出其中的告警时间，设此时间为为Ta。
步骤二：取出告警中的网元ID，在RuleMap中找到此网元ID的时间修正规则表。
步骤三：根据Ta查找时间修正规则表，如果找到，则执行步骤四，找不到则将告警原样上报。
步骤四：假设步骤三中找到的修正规则条目为<Ta，Ra>，则将告警时间设置为Ta+Ra填回告警信息当中，并将此告警上报。
例如，某个网元接收到的告警时间为2015/9/12 15:46:30，对照前面此网元的时间修正规则表，找到修正规则为“+2”，则修正后的告警时间为2015/9/12 15:46:30+2秒，为2015/9/1215:46:32，即修正后的告警时间为2015/9/12 15:46:32。
综上可以看出，通过定时器周期性获取网元上当前的时间，再获取网管单元当前的时间，以得到网管和网元的时间偏差值，利用网管和网元的时间偏差值对网元的管理信息中的时间进行修正，使网管呈现出来的当前管理信息更为准确，达到提高网管信息中记录的时间信息的准确度的目的。
图4为本发明实施例提供的网管系统中时间信息的管理装置的结构图。图4所示装置包括：
第一获取模块401，设置为获取网元和网管单元上时间的偏差值；
修正模块402，设置为在接收到所述网元的管理信息时，利用所述时间的偏差值对所述网元的管理信息中的时间信息进行修正，得到修正后的网元的管理信息。
其中，所述第一获取模块401包括：
获取单元，设置为按照预先设置的时间间隔，获取所述网元当前的时间和所述网管单元当前的时间；
计算单元，设置为计算所述网元当前的时间和所述网管单元当前的时间的差值，得到网元和网管单元上时间的偏差值。
其中，所述装置还包括：
判断模块，设置为在获取网元和网管单元上时间的偏差值之后，判断所述时间的偏差值是否大于预先设置的时间阈值；
