Description

网络状态的监测方法、电子设备及计算机可读介质
交叉引用
本申请要求在2023年4月21日提交中国专利局、申请号为202310458899.0、名称为“网络状态的监测方法、电子设备及计算机可读介质”的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及光通信技术领域，尤其涉及一种网络状态的监测方法、电子设备及计算机可读介质。
背景技术
在无源光网络系统中，光线路终端(Optical Line Terminal，OLT)和一个或者多个光网络单元(Optical Network Unit，ONU)通过光分配网络(Optical Distribution Network，ODN)连接，ODN由主干光纤、分光器件、分支光纤组成。ODN由于外界干扰、自身情况等原因，可能会因此出现OLT和ONU之间的通信短暂中断，对此相关技术中已提供了相应的瞬断处理机制，即当ONU下行方向失去同步或者在一段时间内收不到下行信号时，会暂时进入一个中间状态，例如ITU-T无源光纤网络(Passive Optical Network，PON)的临时等待的断纤(POPUP/O6)状态，IEEE PON的等待(hold on)状态等，处于中间状态的ONU，如果在一定时间内能够恢复收到下行同步或者收到下行信号，则重新进入工作状态，以避免ONU重启或者重新进入注册激活流程，从而避免引起业务质量劣化。
但在如ONU接收光功率处于临界值、ODN链路损耗处于极限、光纤连接头松动、光纤损坏等场景下，可能出现ONU时而能正常接收下行信号，时而不能正常接收下行信号，即ONU会在正常工作状态和通信短暂中断状态间反复跳转，在此情况下，如何确保业务质量仍是本领域急需解决的技术问题。
发明内容

第二方面，本申请实施例提供了一种网络状态的监测方法，由OLT执行，所述方法包括：接收光网络单元ONU发送的第一指示信息和/或第四指示信息；根据所述第一指示信息和/或第四指示信息进行网络状态监测；其中，所述第一指示信息用于指示所述ONU进入网络异常状态的计数结果，和/或，所述计数结果是否大于第一阈值；所述第四指示信息用于指示所述ONU进行了重启或重注册激活、重启或重注册激活的原因信息、重启或重注册激活的时间信息中的至少一项。
第三方面，本申请实施例提供了一种电子设备，包括：存储器、处理器和存储在所述存储器上并可在所述处理器上运行的计算机可执行指令，所述计算机可执行指令被所述处理器执行时实现执行第一方面或第二方面所述的 方法的步骤。

具体实施方式
为了使本技术领域的人员更好地理解本申请中的技术方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
图1示出本申请实施例提供的网络状态的监测方法100的一种流程示意图，该方法可以由电子设备执行，例如ONU。换言之，所述方法可以由安装在电子设备中的软件或硬件来执行。如图1所示，该方法100可以包括以下步骤。
S110，对所述ONU进入网络异常状态的次数进行计数。
其中，所述网络异常状态也可以称为中间状态。本实施例中，根据光网络系统的不同，所述网络异常状态可以不同，如所述网络异常状态可以是ITU-T PON的POPUP/O6状态，也可以是IEEE PON的hold on状态等，在此不做限制。
此外，一种实现方式中，所述ONU在对其进入网络异常状态的次数进行计数时，可通过但不限于配置在ONU中的计数器实现。
S120，根据计数结果进行网络状态监测。
其中，所述ONU在根据计数结果进行网络状态的方式可以有多种，如所述ONU可以自主地根据所述计数结果进行网络状态监测，也可以将所述计数结果发送给OLT，由所述OLT根据所述计数结果进行网络状态监测，还可以在自主根据所述计数结果进行网络状态监测的同时，将所述计数结果发送给OLT，由所述OLT根据所述计数结果进行网络状态监测等，由此，提高网络监测的灵活性。
本实施例中，通过对ONU进入网络异常状态的次数进行计数，并根 据计数结果进行网络状态监测，由此，能够提供一种有效的ONU问题发现机制，以发现所述ONU反复进入网络异常状态(或称作ONU状态反复跳转、下行链路瞬断)的问题，进而确保业务质量。
在此情况下，作为一种可能的实现方式，下面结合方式1和方式2对所述ONU进行网络状态监测的不同方式进行介绍，内容如下。
方式1：ONU向OLT发送所述计数结果。
其中，所述ONU可在确定满足第一条件、且所述ONU由所述网络异常状态进入正常工作状态的情况下，向所述OLT发送第一指示信息，所述第一指示信息用于指示所述计数结果(即所述ONU进入所述网络异常状态的次数)，和/或，所述第一指示信息用于指示所述计数结果是否大于第一阈值。
其中，通过所述第一指示信息的发送，能够使得OLT根据所述第一指示信息进行网络状态的监测、网络问题定位等。本实施例中，所述第一指示信息的传输方式可以有多种，例如，所述第一指示信息可以携带于上行突发信号、光网络单元管理控制接口(ONU Management and Control Interface，OMCI)消息(也可称作OMCI通道消息)、技术报告069(Technical Report 069，TR-069)消息等中，在此不做限制。
基于此，一种可能的实现方式中，假设所述第一指示信息携带于上行突发信号中的第一域中，那么，如图2所示，所述第一域可以为所述上行突发信号中的已有的指示域(如复用已有的Ind域)或新增域(如物理层操作管理维护(PLOAM)域中)。可以理解，图2中的BIP为比特交错奇偶校验(Bit Interleaved Parity)，CRC为循环冗余校验((Cyclic Redundancy Check)，HEC为混合差错控制(Hybrid Error Control)、DBRu为上行分布布喇格反射(Distributed Bragg Reflector)、FS标识成帧子层(Framing Sub-layer)、BufOcc表示缓存占用(Buffer Occupancy)。
当然，在本实施例中，如果所述第一域为新增域，如PLOAM域， 那么，所述新增域中携带的ONU异常状态消息(也可以称作ONU跳转锁定消息(ONU_Live_Lock message)、ONU异常状态消息(ONU_abnormal status message)等)可如表1所示。
其中，表1中的RSSI用于OLT判断ONU的接收功率是否处于临界值，以便于进一步确认ONU在正常工作状态和网络异常状态反复跳转。需要注意的是，所述新增域中携带的信息可以包括但不限于表1中所示，如所述新增域中携带的信息可以比表1所示更多或更少的信息等。
在一实施方式中，所述第一阈值可以默认配置，也可以由ONU本地操作进行配置，还可以通过OLT发送配置命令的方式进行配置等，所述配置命令可以为PLOAM消息、OMCI消息、TR-069消息等，由此能够确保所述第一阈值配置的灵活性。
表1

在一示例性实施例中，所述ONU在满足第一条件，发送所述第一指示信息时，所述第一条件可以包括以下(a)-(b)中的至少一项。
(a)ONU接收到所述OLT发送的第二指示信息，所述第二指示信息用于指示所述ONU上报进入网络异常状态的次数。
也就是说，所述第一指示信息的发送可以由所述OLT触发。基于此，在本实施例中，所述OLT在发送所述第二指示信息时，其可以携带于下行突发信号中，如Get_ONU_Live_Lock_Count消息、Get_ONU_abnormal status_Count消息等。
一种实现方式中，所述Get_ONU_Live_Lock_Count消息或Get_ONU_abnormal status_Count消息的消息形式可以但不限于如表2所示。
(b)达到预定监测周期，所述预定监测周期用于监测所述ONU进入网络异常状态的次数。也就是说，所述ONU在达到预定监测周期时向 所述OLT发送所述计数结果。
(c)定时器超时，所述定时器用于监测所述ONU进入网络异常状态的次数。
(d)确定所述计数结果达到所述第一阈值。其中，所述计数结果可以是总的计数结果，也可以是在预定监测周期或定时器内的计数结果，在此不做限制。
表2
相应的，所述OLT在接收到所述ONU发送的第一指示信息时，可根据所述第一指示信息进行网络状态监测，如在确定所述第一指示信息指示所述ONU进入网络异常状态的计数结果大于第一阈值，向所述ONU发送第三指示信息，所述第三指示信息用于指示所述ONU进行重启或重注册激活；又如在确定所述第一指示信息指示所述ONU进入网络异常状态的计数结果和/或所述计数结果大于第一阈值，向所述ONU发送第五指示信息，所述第五指示信息用于指示清除所述计数结果。
进一步，所述OLT在接收到所述第一指示信息后，除了根据所述第一指示信息进行网络状态监测之外，还可以进行网络瞬断等问题的定位。例如，在本实施例中，所述OLT可确定上行突发丢失的次数，再根据所述上行突发丢失的次数和所述第一指示信息进行网络问题定位。
其中，所述上行突发丢失可以理解为：OLT为ONU分配了上行带宽但没有接收到ONU发送的上行突发。一种实现方式中，考虑到上行突发丢失除了可能是下行方向出现故障，也可能是上行方向出现故障。基于此，所述OLT在确定上行突发丢失的次数大于第二阈值，且所述第一指示信息指示了ONU进行网络异常状态的次数的计数结果，如大于第一阈值时，可确定下行方向出现了网络瞬断问题，进而处理所述网络瞬断问题，由此能够实现网络问题的准确定位，确保业务质量。其中，所述第二阈值可以通过默认设置等方式实现。
可以理解，与所述第二指示信息类似，所述第三指示信息、所述第五指示信息也可以携带于下行突发信号中，如Get_ONU_Live_Lock_Count消息、Get_ONU_abnormal status_Count消息等，对此不再赘述。
方式2：根据所述计数结果对所述网络异常状态进行处理。
其中，所述ONU在根据所述计数结果对所述网络异常状态进行处理可以包括根据所述计数结果进行重启或重注册激活。
当然，所述ONU在根据所述计数结果进行重启或重注册激活时，可以自身或本地确定进行重启或重注册激活，也可以根据OLT发送的指示信息进行重启或重注册激活。例如，所述ONU可在确定所述计数结果大于第一阈值时，自身或本地确定进行重启或重注册激活。或，所述ONU接收到所述OLT发送的第三指示信息的情况下，进行重启或重注册激活。其中，所述第三指示信息用于指示所述ONU进行重启或重注册激活，所述第三指示信息可以是所述OLT根据接收到的第一指示信息所指示的计数结果确定。
值的注意的是，所述ONU如果确定自身或本地进行重启或重注册激活的情况下，可在进行重启或重注册激活时，或在进行重启或重注册激活之前或之后，向所述OLT发送第四指示信息，以向所述OLT指示所述 ONU进行重启或重注册激活、重启或重注册激活的原因信息、重启或重注册激活的时间信息中的至少一项。
其中，如果所述OLT同时接收到所述第一指示信息和所述第四指示信息，且根据所述第一指示信息确定所述ONU需要重启或重注册激活的情况下，可根据所述第四指示信息确定所述ONU进行了重启或重注册激活，以及取消所述第三指示信息的发送。
可选的，与所述第一指示信息类似，所述第四指示信息也可以携带于上行突发信号中的第一域中，那么，如图2所示，所述第一域可以为所述上行突发信号中的已有的指示域(如复用已有的Ind域)或新增域(如物理层操作管理维护(PLOAM)域中)，在此不做限制。
进一步，一种可能的实现方式中，为了实现持续的网络状态监测，以及确保网络状态监测的准确性，那么所述ONU可在根据所述计数结果进行网络状态监测(如向OLT发送第一指示信息)后，可清除所述计数结果，以及重新对所述ONU进入所述网络异常状态的次数进行计数，以实现下一轮的网络状态监测。
其中，作为一种实现方式中，所述ONU在清除所述计数结果时，也可以由自身确定，如可在向所述OLT发送所述计数结果的情况下，清除所述计数结果；还可以根据OLT的指示确定，如接收所述OLT发送的第五指示信息，根据所述第五指示信息清除所述计数结果。
基于前述方法实施例的描述，下面结合示例1-示例5对本申请提供的网络状态的监测过程作进一步示例性描述。其中可以理解，本申请提供的网络状态的监测过程可以包括但不限于如下示例1-示例5。
示例1
如图3a所示，假设在ITU-T PON系统中，所述网络异常状态为POPUP状态，即所述ONU可能因为下行信号中断(LODS)、下行失去同步等原因从正常工作状态(如图3a所示操作状态(Operation state)(O5))进入 POPUP状态(如图3a所示的间歇性(Intermittent)LODS状态(O6))，并对其进入POPUP状态的次数进行计数，那么，如果计数结果(即进入POPUP状态的次数)超过第一阈值，则所述ONU会在其再次进入正常工作状态(如图3a所示Operation state(O5))时向OLT报告该事件，即通过第一指示信息向OLT(如图3a所示的操作状态(O5))指示所述计数结果和/或所述计数结果超过所述第一阈值，从而实现网络状态的监测。
其中，所述第一阈值可以默认设置为72000次，如此设置的原因是：假设所述ONU每5次进入一次POPUP状态，以小时为监测周期，那么，虽然在其正常工作情况下也可能进入网络异常状态，其次数是有限的，即远小于72000次。需要注意，所述第一阈值可以为但限于前述的72000次。
当然，所述ONU在报告完毕后，可如图3a所示清除所述计数结果并重新对其进入POPUP状态的次数进行计数，以实现持续的网络状态监测。
另外，关于所述第一指示信息的相关描述可参照前述内容，在此不再赘述。
示例2
如图3b所示，假设在ITU-T PON系统中，所述网络异常状态为POPUP状态，所述ONU可能因为下行信号中断、下行失去同步等原因从正常工作状态(如图3b所示操作状态(O5))进入POPUP状态(如图3b所示的间歇性LODS状态(O6))，并对其进入POPUP状态的次数进行计数，那么，当达到预定监测周期(或称作计数周期结束)、且所述计数结果(即进入POPUP状态的次数)超过第一阈值，则所述ONU会在其再次进入正常工作状态时向OLT报告该事件，即通过第一指示信息向OLT指示所述计数结果和/或所述计数结果超过所述第一阈值，从而实现网络状态的监测，从而实现网络状态的监测。
其中，所述第一阈值可以为可以默认设置为18000次，如此设置的 原因是：假设所述ONU每50ms进入一次POPUP状态，以15分钟为预定监测周期(或称为观察期)，那么，其进入POPUP状态的次数为18000次。需要注意，所述第一阈值可以为但限于前述的18000次。
另外，关于所述第一指示信息的相关描述可参照前述内容，在此不再赘述。
当然，所述ONU在报告完毕后，可如图3b所示清除所述计数结果并重新对其进入POPUP状态的次数进行计数，以实现持续的网络状态监测。
示例3
如图3c所示，假设在ITU-T PON系统中，所述网络异常状态为POPUP状态，所述ONU可能因为下行信号中断、下行失去同步等原因从正常工作状态(如图3c所示操作状态(O5))进入POPUP状态(如图3c所示的间歇性LODS状态(O6))，并对其进入POPUP状态的次数进行计数，那么，当达到预定监测周期(或称作计数周期结束)、且所述计数结果(即进入POPUP状态的次数)超过第一阈值，则所述ONU会在其再次进入正常工作状态时，通过第四指示信息向OLT指示其进行了重启或重注册激活，以及在完成所述第四指示信息发送后进行重启或重注册激活以进入图3c所示的初始化状态(Initial state)(O1)，并记录重启原因和重启时间。
或者，所述当达到预定监测周期(或称作计数周期结束)、且所述计数结果(即进入POPUP状态的次数)超过第一阈值，则所述ONU会进行重启或重注册激活，以及在完成重启或重注册激活并进入图3c所示的初始化状态(O1)之后，记录重启原因和重启时间，并根据记录的信息向所述OLT发送第四指示信息，以向OLT指示其进行了重启或重注册激活，以及重启或重注册激活的原因信息、时间信息等。
其中，所述第一阈值的设置可参前述示例1和示例2中的相关描述，为避免重复，在此不再赘述。
当然，一种实现方式中，所述ONU在发送所述第四指示信息时，所述第四指示信息还可以指示或携带有重启原因信息、重启时间信息等，在此不做限制。
另外，关于所述第四指示信息的相关描述可参照前述内容，在此不再赘述。
示例4
在ITU-T PON系统中，所述网络异常状态为POPUP状态，所述ONU可能因为下行失去同步等进入POPUP状态，并对其进入POPUP状态的次数进行计数，那么，所述OLT可以根据需要向ONU发送第二指示信息(即读取命令)，所述ONU在接收到所述第二指示信息时，通过第一指示信息向所述OLT指示计数结果，即所述ONU进入POPUP状态的次数，第一指示信息中的其他信息，例如abnormal status、RSSI、重启相关信息等，各自都按照需要报告或者不报告。
值得的注意的是，所述第一指示信息在通过OMCI通道消息实现时，可在ANI-G管理对象中增加以下属性：
Abnormal status count:进入异常状态的次数，4字节，可读写。
另外，重用ANI-G管理对象中的光信号电平(Optical signal level)属性传递RSSI。其中，所述光信号电平属性用于报告总下行光信号电平的当前测量值。它的值是一个2s补码整数，表示1mW(即1dBm)，粒度为0.002dB。可选的，所述光信号电平属性的长度可以为2字节。
当然，所述ONU在完成所述第一指示信息发送后，可清除所述计数结果以及重新对自身进入POPUP状态的次数进行计数。
另外，关于所述第一指示信息、第二指示信息的相关描述可参照前述内容，在此不再赘述。
示例5
在ITU-T PON系统中，所述网络异常状态为POPUP状态，所述ONU 可能因为下行失去同步等进入POPUP状态，并对其进入POPUP状态的次数进行计数，那么，所述ONU可根据需求(如计数结果大于第一阈值、定时器超时、达到预定监测周期等)向所述OLT发送第一指示信息，以指示计数结果(即所述ONU进入POPUP状态的次数)，并在完成所述第一是指示信息的发送后，重新对自身进入POPUP状态的次数进行计数，所述第一指示信息中的其他信息，例如abnormal status、RSSI、重启相关信息等，各自都按照需要报告或者不报告。
值的注意的是前述示例1-示例5中，所述OLT在接收到第一指示信息后，可根据所述第一指示信息进行网络状态监测、网络问题定位等。例如，所述OLT可根据第一指示信息向所述ONU发送第三指示信息，以指示所述ONU进行重启或重激活注册等。
又例如，所述OLT可根据所述第一指示信息和上行突发丢失次数进行网络问题定位等，在此不做限制。
如图4所示，为本申请一示例性实施例提供的网络状态的监测的方法400的流程示意图，该方法可由电子设备执行，如OLT，具体可由安装于电子设备中的硬件或软件执行。如图4所示，该方法400可以包括以下步骤。
S410，接收光网络单元ONU发送的第一指示信息和/或第四指示信息。
S420，根据所述第一指示信息和/或进行网络状态监测。
其中，所述第一指示信息用于指示所述ONU进入网络异常状态的计数结果，和/或，所述计数结果是否大于第一阈值；所述第四指示信息用于指示所述ONU进行了重启或重注册激活、重启或重注册激活的原因信息、重启或重注册激活的时间信息中的至少一项。
在一实施方式中，所述第一指示信息或所述第四指示信息携带于上行突发信号中的第一域中，所述第一域为所述上行突发信号中的已有的 指示域或新增域。
