Description

信息上报方法及装置、计算机存储介质 技术领域
本发明涉及光网络通信技术，尤其涉及一种信息上报方法及装置、计算机存储介质。
背景技术
无源光网络是由局端设备如光线路终端(OLT，Optical Line Terminal)和多个终端设备如光网络单元(ONU，Optical Network Unit)组成。ONU之间采用时分复用的方式进行报文的上传，每个ONU上传报文的时间由OLT来分配和控制。在OLT动态向ONU分配带宽的情况下，先由ONU向OLT进行带宽上报，OLT根据ONU带宽上报的情况通过动态带宽分配DBA算法进行ONU的带宽下发。
ONU设备中，当报文入队成功时，会将当前队列中报文缓存的字节数上报给OLT设备。在报文输出到无源光网络媒体访问控制(PON MAC，Passive Optical Network Media Access Control)时，ONU设备可以选择对业务进行限速处理。在不进行业务的限速处理时，业务可以按照OLT分配的带宽调度输出到PON MAC，经过封装后发送到OLT设备；在业务进行调度限速时，由于限速的影响，可能导致发送到OLT设备的报文带宽小于OLT分配给该ONU的带宽的情况。
通常ONU的做法是直接将缓存中的报文字节数通过ONU的上报机制报告给OLT设备，由OLT来分配和管理下发给各个ONU的带宽，没有考虑到ONU一直上报带宽非常大的情况。如果ONU实际上送的报文带宽和OLT下发给ONU的带宽存在巨大的差值时，即上报的报文缓存字节数很大，而实际发送到OLT设备的报文字节数较少，就会造成ONU上传到OLT的 带宽资源的浪费，而每次ONU都上报申请较大的带宽，OLT根据上报的字节数进行带宽分配，会因为这些假申请，影响到其他正常工作的ONU的业务上传。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
图1为本发明实施例的信息上报方法的流程示意图，如图1所示，本示例的信息上报方法包括以下步骤：
步骤101，ONU确定当前需上报的业务的数据量，获取令牌桶中的令牌的数值。
本发明实施例中，所述令牌的数值用于指示所述ONU能够上传的业务的数据量的最大值。
本发明实施例中，所述方法还包括：确定需要限速处理时，进行令牌的添加；
将所添加的令牌和令牌桶已有令牌相加，得到新的令牌数；
将所述新的令牌数作为令牌桶中当前的令牌数。
本发明实施例中，所述确定当前需上报的业务的数据量，包括：
所述业务老化时，将所述当前需上报的业务的数据量数值减去老化的业务的数据量数值，其差值作为更新后的当前需上报的业务的数据量数值。
本发明实施例中，所谓报文老化，即为队列中的所有报文设置最晚传输时刻，若当前时刻已过了报文的最晚传输时刻，则认为队列中的报文老化，即在最晚传输时刻仍未能发出报文，该报文再次发送毫无意义，需要将其从队列中清除出去。
步骤102，ONU对所述当前需上报的业务的数据量和所述最大能上传到OLT的数据量进行比较，选取数据量较小的数值。
本发明实施例中，当令牌桶中的剩余令牌数或所述当前需上报的业务的数据量发生更新时，选取较小的数值作为向所述OLT上报的数据量数值。
本发明实施例中，还需要实时对报文进行入队管理，具体地，有新报文入队时，将新入队的报文的数据量以及队列中当前报文的数据量之和作为当前需上报的业务的数据量。
步骤103，在第一设定周期到来时，将所选取的数据量的数值向所述 OLT上报。
本发明实施例中，在第二设定周期到来时，进行令牌的添加；将所添加的令牌和令牌桶已有令牌相加，得到新的令牌数；将所述新的令牌数作为最大能上传到所述OLT的数据量；以及
对所述当前需上报的业务的数据量进行更新；
在第一设定周期到来之前，持续对令牌桶中的令牌数以及所述当前需上报的业务的数据量的更新；
在第一设定周期到来时，将更新后的令牌数和更新后的当前需上报的业务的数据量进行比较，选取较小的数值作为向所述OLT上报的数据量数值；
其中，所述第二设定周期小于所述第一设定周期。具体地，第一设定周期是用于向OLT上报当前需传输的待数据量的数值的周期，在第一设定周期到来时，将需传输的数据量上报至OLT；而第二设定周期则是令牌桶的更新周期。第一设定周期可以是第二设定周期的整数倍，如第一设定周期至少是第二设定周期的2倍以上。
本发明实施例中，将所选取的数据量的数值向所述OLT上报后，本示例的信息上报方法还包括：
将需上报的业务的数据量减去所上报的数据量的数值，将差值作为当前需上报的业务的数据量数值；
将令牌桶中的剩余令牌数减去所上报的数据量的数值，将差值作为更新后的剩余令牌数。
本发明实施例的技术方案，在消除了在带宽上报时，出现下发带宽和实际发送带宽相差太大的情况，使得OLT进行DBA处理时更加准确，避免了ONU在上传报文时的带宽浪费，以及ONU之间进行带宽分配时的抢占问题，提高了整个OLT设备下ONU带宽上传的利用率。
以下通过具体示例，进一步阐明本发明实施例技术方案的实质。
本发明实施例针对现有技术中存在的ONU上报带宽和实际上传带宽不匹配带来的ONU业务上传的带宽浪费和ONU之间的带宽抢占问题和缺陷而提出。以下详细阐明其实现过程。
图2为本发明实施例的信息上报装置的具体实现结构示意图，如图2所示，本发明实施例的信息上报装置可以通过图2所示的结构实现，包括以下处理单元：队列管理单元、调度单元、报文输出单元，PON MAC单元以及带宽上报计算单元；其中：
队列管理单元：进行报文入队管理，在带宽上报处理时，将入队的报文的字节数送给带宽上报计算单元。
调度单元：进行报文的调度输出、业务的限速、报文的老化处理；在带宽上报处理时，会将老化的字节数送给带宽上报计算单元。
报文输出单元：响应ONU的PON MAC单元的请求，将报文输出给PON MAC单元，同时将输出报文信息发送给带宽上报计算单元。
PON MAC单元：接收OLT侧下发的带宽授权信息，向报文输出单元请求数据发送；并向OLT进行发送带宽报告信息。
带宽上报计算单元：完成带宽上报计算。根据对业务的限速要求、队列管理新增报文的字节数、实际上报的字节数、实际输出的报文字节数，进行计算和比较，得到上报的结果，将结果送到PON MAC单元，由PON MAC单元完成带宽信息上报。
本发明实施例的技术方案，在消除了在带宽上报时，出现下发带宽和实际发送带宽相差太大的情况，使得OLT进行DBA处理时更加准确，避免了ONU在上传报文时的带宽浪费，以及ONU之间进行带宽分配时的抢占问题，提高了整个OLT设备下ONU带宽上传的利用率。
图3为本发明实施例的带宽信息计算示意图，如图3所示，本发明实 施例的带宽信息计算包括以下处理步骤：
在进行带宽上报计算时，通过对当前需要上报的业务在缓存中的字节数和最大能上传到OLT的报文字节数即剩余令牌进行比较，选取两个数值中较小的数值。在达到设定的时间时，累计上报的报文数据量的数值，上报给PON MAC单元，由PON MAC单元根据累计数值进行上报处理。
①当报文经队列管理入队成功后，将新入队报文的字节数送给带宽上报计算单元，带宽上报计算单元根据新增的上报字节数计算缓存中报文的字节数。
②当调度单元中的业务发生了老化处理，将老化报文的字节数送给带宽上报计算单元，带宽上报计算单元根据被老化的报文的字节数，重新计算缓存中的报文字节数。
③带宽上报计算单元根据业务是否进行限速处理进行令牌的添加处理，添加的令牌和令牌桶已有令牌相加，得到新的令牌数。
④当令牌桶的剩余令牌数和缓存中报文的字节数发生更新时，使用新的令牌数和缓存中报文字节数进行比较，选择较小的数值作为真正需要上报的字节数。
⑤为了防止过快上报，影响PON MAC的内部的上报发送过程，选择按照固定时间向PON MAC发送上报数据。需要上报的字节数在这里进行累计，当配置的时间到达后，进行上报信息的输出。
⑥当上报信息输出到PON MAC后，缓存中报文字节数减去上报输出的字节数，更新缓存中报文字节数。
⑦当上报信息输出到PON MAC后，剩余令牌桶减去上报输出报文的字节数，更新剩余令牌数。
⑧PON MAC获得OLT带宽授权后，进行报文的发送处理，PON MAC单元向报文输出单元进行请求，报文输出单元将调度出的报文输出到PON  MAC，PON MAC封装后发送到OLT设备。
下面结合图3，对本发明实施例的技术方案的实施作进一步的举例说明：
1)假设队列管理收到一个包长为128字节的报文，将该报文信息送到带宽上报计算单元。这里假设缓存中原有报文字节数为200；收到新增上报字节数后，缓存中报文数变为328字节。
2)缓存中报文数目发生变化触发上报计算，读取当前令牌数，这里假设此时的令牌数为0，比较缓存字节数和令牌数后，此次不用做上报累计计算。
3)收到一个老化处理请求，老化报文长度为64。则需要更新缓存的报文字节数，缓存的原有字节数减去老化字节数，缓存报文字节数更新为264。
4)在缓存报文字节数更新后，触发上报计算，读取当前令牌数，令牌数依然为0，比较缓存字节数和令牌数后，此次不用做上报累计计算。
5)经过1个ΔT1，进行令牌的添加，添加令牌数为16，则剩余令牌数更新到16。
6)更新令牌也触发上报计算，读取缓存中报文字节数，数值为264。剩余令牌数和缓存中报文字节数进行比较，选择16作为上报数，送到上报累计输出部分。
7)这里假定上报累计输出的原有累计值为0，则更新后的累计上报值为16。
8)由于上报数已经送到上报累计部分，则缓存中报文字节数和剩余令牌数都需要更新，减去上报字节数后，缓存报文字节数为248，剩余令牌数为0；
9)再经过1个ΔT1，进行令牌的添加，添加令牌数为16，则剩余令牌数更新到16。再进行与前述6)、7)、8)相同的操作，缓存中报文字节数为 232，剩余令牌数为0。
10)此时，更新后的上报累计为32。
11)再过6个ΔT1后，重复前述6)、7)、8)相同的操作，缓存中报文数为136，剩余令牌为0，更新后的上报累计为128。
12)此时，达到了ΔT2时刻，需要将累计上报值128发往PON MAC，累计上报值清零。
13)再过8个ΔT1后，重复前述6)、7)、8)相同的操作，缓存中报文数为变为8，剩余令牌为0。更新后的上报累计为128。
14)再过1个ΔT1后，重复前述6)、7)、8)相同的操作，缓存中报文数为变为0，剩余令牌为8。更新后的上报累计为136。
15)到了ΔT2时刻，需要将累计上报值136发往PON MAC，累计上报值清零。
16)再过1个ΔT1后，剩余令牌数更新为24，缓存报文数为0，比较后不用累计上报。
