Description

控制通道终端的运行状态的方法和装置 技术领域
本申请涉及但不限于通信领域。
背景技术
随着网络技术的发展，可以利用网络传输大量的语音、数据、视频等业务，因此对带宽的要求不断提高，无源光网络(Passive Optical Network，PON)就是在这种需求下产生的。PON系统的拓扑结构如图1所示，PON系统通常由局侧的光线路终端(Optical Line Terminal，OLT)、用户侧的光网络单元(Optical Network Unit，ONU)和光分配网络(Optical Distribution Network，ODN)组成，通常采用点到多点的网络结构。ODN由单模光纤和光分路器、光连接器等无源光器件组成，为OLT和ONU之间的物理连接提供光传输媒质。
随着带宽需求的进一步增加，提出了的TWDM PON(Time-and Wavelength-Division Multiplexed PON，基于时分和波分复用的无源光网络)系统，其拓扑结构如图2所示，TWDM PON网络中有一个OLT，光分布网络和多个ONU，每个OLT有多个OLT通道终端。TWDM PON网络中有多个TWDM PON通道，每个OLT通道终端和一组ONU工作在一个TWDM PON通道上，每个TWDM PON通道包括一个下行波长通道和一个或者多个上行波长通道。每个TWDM PON通道上一个OLT通道终端管理一组ONU，一组ONU用于发送上行数据的上行波长相同，并且接收下行数据的下行波长也相同，所述一组ONU中的不同ONU通过时分复用的方式传输上行数据。不同TWDM PON通道的下行波长不同，不同OLT管理的每组ONU使用的上行波长也不同。每个ONU按照OLT的命令在特定的上行时隙内发送上行数据。另外，为了实现负载均衡、节能和降低ONU的库存种类等原因，TWDM PON系统中的ONU的发送波长和接收波长是可以调谐的，OLT可以命令ONU调谐工作波长，因此ONU可以工作在任何一个TWDM PON通道中。根据业务数据的传输需求，OLT会配置OLT通道终端与ONU进行 通信。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
当PON网络的业务量较少时，OLT可以只开通部分OLT通道终端用于和ONU进行通信，并关闭一个或者多个OLT通道终端的光模块，使部分OLT通道终端进入节能状态。当PON网络的业务量较多时，OLT需要增加开启部分OLT通道终端，使其从节能状态进入到工作状态。但相关技术中没有提供上述OLT通道终端进入节能和恢复工作状态的方法。

本发明的实施方式
下面将结合附图及实施例对本发明的实施方式进行描述。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3为本发明实施例提供的控制通道终端的运行状态的方法的流程图。图3所示方法，包括：
步骤301、在TWDM PON系统中包括多个OLT通道终端时，第一OLT通道终端获取用于控制运行状态发生切换的切换指令；
步骤302、所述第一OLT通道终端根据所述切换指令，对所述第一OLT通道终端的运行状态进行切换，其中所述运行状态包括节能状态和工作状态。
本发明提供的方法实施例，通过获取切换指令，控制第一OLT通道终端 的运行状态的变化，实现节能和保证数据传输的平衡。
下面对上述方法作进一步说明：
其中，所述第一OLT通道终端获取运行状态的切换指令，包括：
方式一：所述第一OLT通道终端接收OLT发送的进入节能状态或进入工作状态的切换指令；
其中，OLT在检测到需要传输的业务数据的数据量增加或者部分PON通道出现故障时，OLT通知进入节能状态的第一OLT通道终端切换到工作状态；OLT在检测到需要传输的业务数据的数据量减少，则OLT通知进入工作状态的第一OLT通道终端切换到节能状态。
方式二：所述第一OLT通道终端接收其他OLT通道终端发送的进入节能状态或进入工作状态的切换指令；
其中，其他OLT通道终端在检测到需要传输的业务数据的数据量增加或者部分PON通道出现故障时，通知进入节能状态的第一OLT通道终端切换到工作状态；其他OLT通道终端在检测到需要传输的业务数据的数据量减少，则通知进入工作状态的第一OLT通道终端切换到节能状态。
方式三：所述第一OLT通道终端检测到需要传输的业务数据的数据量减少或为零，生成进入节能状态的切换指令。
由上可以看出，唤醒指令可以由外部接收，如OLT或其他OLT通道终端来发送，也可以由自身产生。
在本发明提供的一种实施方式中，所述第一OLT通道终端根据所述切换指令，对所述第一OLT通道终端的运行状态进行切换，包括：
如果所述切换指令是根据需要传输的业务数据的数据量减少的传输需求信息生成的，则所述第一OLT通道终端向第二OLT通道终端请求进入节能状态，并将需要调谐到第二OLT通道终端对应的基于时分和波分复用的无源光网络TWDM PON通道的ONU传输汇聚层配置信息发送给所述第二OLT通道终端；
在接收到所述第二OLT通道终端发送的同意第一OLT进入节能状态的消息后，所述第一OLT通道终端进入节能状态。
其中，所述第二OLT通道终端为：承担第一OLT通道终端未完成的数据传输任务的OLT通道终端。
在第一OLT通道终端检测到业务数据的数量减少时，即该第一OLT通道终端仍有业务数据未发送时，为了保证在第一OLT通道终端进入节能状态后，不影响第一OLT通道终端对应的ONU的数据传输，通过将ONU传输汇聚层配置信息发送给第二OLT通道终端，使得第二OLT通道终端继续完成第一OLT通道终端未完成的数据传输任务，并在接收到第二OLT通道终端同意代替第一OLT通道终端继续完成数据传输任务后，再进入节能状态，从而在实现节能的前提下，保证数据的连续性传输。
其中，所述第一OLT通道终端向第二OLT通道终端请求进入节能状态，并将需要调谐到第二OLT通道终端对应的TWDM PON通道的光网络单元ONU传输汇聚层配置信息发送给所述第二OLT通道终端之后，所述方法还包括：
所述第二OLT通道终端根据所述第一OLT通道终端发送的ONU传输汇聚层配置信息，在所述第二OLT通道终端管理的TWDM PON通道上为所述第一OLT通道终端对应的ONU分配带宽；
所述第二OLT通道终端在完成带宽分配后，判断是否接收到新的ONU向自己管理的TWDM PON通道发送上行帧；
如果所述第二OLT通道终端接收到新的ONU在自己管理的TWDM PON通道上发送上行帧，则同意第一OLT通道终端进入节能状态。
其中，所述第二OLT通道终端在所述第二OLT通道终端管理的TWDM PON通道上为所述第一OLT通道终端对应的ONU分配带宽后，完成代替第一OLT通道终端继续传输数据的准备工作，如果能接收到原来与第一OLT通道终端进行通信的ONU在自己管理的TWDM PON通道上发送上行帧，表示能够代替其完成后续数据的发送，则允许第一OLT通道终端进入节能状态，否则，拒绝第一OLT通道终端进入节能状态。
上述内容是针对需要传输的业务数据的数据量减少时进行说明的，与上述情况不同的是，下面对需要传输的业务数据的数据量为零时的情况进行说 明：
如果所述切换指令是根据需要传输的业务数据的数据量为零的传输需求信息生成的，则所述第一OLT通道终端进入节能状态，并向所述TWDM PON中除所述第一OLT通道终端之外的所有OLT通道终端发送第一OLT通道终端进入节能状态的信息。
在第一OLT通道终端检测到业务数据的数量为零时，即该第一OLT通道终端没有业务数据需要发送，即第一OLT通道终端是否休眠，不会给与其对应的ONU的数据传输造成影响，因此，第一OLT通道终端可直接进行节能状态，并告知其他OLT通道终端该信息即可。
上文对第一OLT通道终端切换到节能状态的切换进行了说明，下面对第一OLT通道终端切换到工作状态的切换进行说明：
其中，所述第一OLT通道终端根据所述切换指令，对所述第一OLT通道终端的运行状态进行切换，包括：
如果所述切换指令是根据需要传输的业务数据的数据量增加或TWDM PON通道出现故障的信息生成的，则所述第一OLT通道终端进入工作状态，并接收调谐到所述第一OLT通道终端对应的TWDM PON通道的ONU传输汇聚层配置信息，并利用接收到的ONU传输汇聚层配置信息执行带宽分配操作。
其中，该切换指令可以是通过如下方式获取的，包括：
所述第一OLT通道终端接收到OLT发送的进入节能状态的切换指令；
其中，OLT在检测到需要传输的业务数据的数据量增加或者部分PON通道出现故障时，OLT通知进入节能状态的OLT通道终端切换到工作状态；
或者，
所述第一OLT通道终端接收其他OLT通道终端发送的进入节能状态或进入工作状态的切换指令；
其中，当TWDM PON中除所述第一OLT通道终端之外的其他OLT通道终端在检测到需要传输的业务数据的数据量增加，可通知进入节能状态的第一OLT通道终端切换到工作状态。
在上述流程中，通过获取ONU传输汇聚层配置信息，并利用接收到的ONU传输汇聚层配置信息执行带宽分配操作，利用分配的带宽与ONU的通信，实现数据传输的目的，有效减少网络中数据的传输压力。
本发明实施例还提供一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令用于执行上述控制通道终端的运行状态的方法。
