本申请所示的方案，PON包括主ONT和至少一个边缘ONT，至少一个边缘ONT包括第一边缘ONT，第一边缘ONT可以检测与主ONT的组网模式，在组网模式为第一组网模式的情况下，第一边缘ONT接收主ONT下发的配置内容，基于配置内容配置第一边缘ONT。在组网模式为第二组网模式的情况下，第一边缘ONT将自身配置作为主ONT的桥接ONT或者进入休眠模式。这样，PON中的边缘ONT可以自动的检测与主ONT的组网模式，并且设置自己的状态，而不 需要人工设置，所以可以提升PON的组网效率。
在一种可能的实现方式中，配置内容包括工作模式、业务配置或网络配置中的一项或多项，其中，工作模式为桥接模式或路由模式。业务配置指示第一边缘ONT所进行的业务(如视频、语音、文本等)、网络配置指示第一边缘ONT的网络信息，如带宽等。这样，主ONT可以对管理的边缘ONT进行全面的配置。
在一种可能的实现方式中，第一边缘ONT检测到不是由主ONT供电，且能接收到主ONT发送的下行报文，确定与主ONT的组网模式为第一组网模式；第一边缘ONT检测到由主ONT供电或者通过高速接口与主ONT连接，确定与主ONT的组网模式为第二组网模式。
本申请所示的方案，第一边缘ONT可以检测是否由主ONT供电，在检测到由主ONT供电时，可以确定组网模式为第二组网模式。在检测到不是由主ONT供电时，可以进一步判断是否接收到主ONT发送的下行报文。如果第一边缘ONT接收到主ONT发送的下行报文，确定组网模式为第一组网模式。或者第一边缘ONT可以检测是否通过高速接口与主ONT连接，在检测到通过高速接口与主ONT连接时，可以确定组网模式为第二组网模式。此处第一边缘ONT检测是否由主ONT供电，可以是检测与主ONT连接的输入电流模块是否开启，开启说明是由主ONT供电，否则说明不是由主ONT供电。这样，可以准确的判断组网模式。
在一种可能的实现方式中，在工作模式为路由模式的情况下，该方法还包括：第一边缘ONT在接收到所述第一边缘ONT连接的终端设备发送的第一上行报文时，将第一上行报文中的源网络互连协议(internet protocol，IP)地址转换为公网IP地址，将地址转换后的第一上行报文转发至主ONT；第一边缘ONT在接收到主ONT发送的第一下行报文时，将第一下行报文中的目的IP地址转换为私网IP地址，将地址转换后的第一下行报文转发至第一边缘ONT连接的终端设备。
本申请所示的方案，第一边缘ONT处于路由模式下，即作为独立的无线路由设备使用，主ONT也作为独立的无线路由设备使用。终端设备向外网发送第一上行报文的处理过程：终端设备在接入第一边缘ONT之后，终端设备向第一边缘ONT发送第一上行报文，第一上行报文中的源IP地址为终端设备的私网IP地址。第一边缘ONT在接收到第一上行报文时，第一边缘ONT可以将第一上行报文中的源IP地址转换为对应的公网IP地址。然后第一边缘ONT将转换后的第一上行报文转发至主ONT。主ONT可以对转换后的第一上行报文向外发送，发送至外网。或者主ONT可以对转换后的第一上行报文中的公网IP地址进行二次转换，转换为主ONT存储的公网IP地址，然后将二次转换后的第一上行报文向外发送，发送至外网。终端设备接收外网发送的第一下行报文的处理过程：主ONT接收到外网发送的第一下行报文，主ONT可以将第一下行报文转发至第一边缘ONT，或者主ONT可以将第一下行报文中的目的IP地址转换为第一边缘ONT存储的公网IP地址，然后将地址转换后的第一下行报文转发至第一边缘ONT。第一边缘ONT可以将接收到的第一下行报文中的目的IP地址对应转换为对应的终端设备私网IP地址，将地址转换后的第一下行报文转发至终端设备。这样，第一边缘ONT可以单独作为一个无线路由设备使用。
在一种可能的实现方式中，在工作模式为桥接模式的情况下，或者第一边缘ONT配置作为主ONT的桥接ONT之后，该方法还包括：第一边缘ONT在接收到所述第一边缘ONT连接的终端设备发送的第二上行报文时，将第二上行报文转发至主ONT；第一边缘ONT在接收到主 ONT发送的第二下行报文时，将第二下行报文转发至所述第一边缘ONT连接的终端设备。
本申请所示的方案，终端设备向外网发送第二上行报文的过程：终端设备在接入第一边缘ONT之后，终端设备向第一边缘ONT发送第二上行报文，第一边缘ONT不对第二上行报文进行处理，将接收到的第二上行报文发送至主ONT。如果主ONT与第一边缘ONT是二层桥接模式，则主ONT可以按照第二上行报文中的媒体访问控制(media access control，MAC)地址，对第二上行报文进行转发，而不对第二上行报文进行处理。如果主ONT与第一边缘ONT是三层桥接模式，则主ONT将第二上行报文中的源IP地址，转换为对应的公网IP地址，然后将转换后的第二上行报文发送至外网。
终端设备接收外网发送的第二下行报文的过程：外网向主ONT发送第二下行报文，如果主ONT与第一边缘ONT是二层桥接模式，则主ONT可以按照第二下行报文中的MAC地址，将第二下行报文转发至第一边缘ONT。如果主ONT与第一边缘ONT是三层桥接模式，则主ONT将第二下行报文中的目的IP地址，转换为对应的终端设备的私网IP地址，然后将转换后的第二下行报文发送至第一边缘ONT。第一边缘ONT按照私网IP地址，将第二下行报文发送至私网IP地址指示的终端设备。这样，在第一边缘ONT处于主ONT的桥接ONT时，也可以进行报文转发处理。
在一种可能的实现方式中，第一边缘ONT在检测到组网模式为第一组网模式的情况下，该方法还包括：第一边缘ONT接收主ONT广播的发现消息，其中，发现消息包括第一标识信息，第一标识信息为主ONT的标识信息；第一边缘ONT在确定第一标识信息为存储的已知主ONT的标识信息后，向主ONT发送第二标识信息，其中，第二标识信息为第一边缘ONT的标识信息；第一边缘ONT接收主ONT下发的配置内容，包括：第一边缘ONT接收主ONT在根据第二标识信息确定第一边缘ONT为已知边缘ONT后发送的配置内容。
本申请所示的方案，第一边缘ONT接收主ONT广播的发现消息，该发现消息包括主ONT的标识信息，即第一标识信息。第一边缘ONT在确定第一标识信息为已知主ONT的标识信息后，向主ONT发送第二标识信息，第二标识信息为第一边缘ONT的标识信息。主ONT在识别第二标识信息为已知边缘ONT的标识信息后，向第一边缘ONT发送配置内容。第一边缘ONT接收该配置内容。这样，由于在边缘ONT添加至主ONT时，可以实现双向认证，防止其它非约定边缘ONT接入，所以可以使PON的组网更安全。
在一种可能的实现方式中，第一边缘ONT在检测到与主ONT的组网模式为第一组网模式的情况下，第一边缘ONT与主ONT之间的连接为PON连接、点对点(peer-to-peer，P2P)光纤连接、P2P网线连接或无线连接中的一种或多种。

本申请所示的方案，主ONT检测组网模式，在检测到组网模式为第一组网模式时，向第一边缘ONT下发配置内容，在检测到组网模式为第二组网模式时，为第一边缘ONT进行供电。 这样，主ONT可以自动的检测组网模式，并且自动执行配置边缘ONT，或者自动为边缘ONT供电，而不需要人工设置，所以可以提升PON的组网效率。
在一种可能的实现方式中，主ONT检测组网模式，包括：主ONT检测到目标功能开启，确定组网模式为第一组网模式；主ONT检测到目标功能未开启，确定组网模式为第二组网模式，其中，目标功能指用于管理至少一个边缘ONT的功能。
本申请所示的方案，目标功能为OLT功能，即管理边缘ONT的功能。目标功能在主ONT中对应有虚拟模块，控制该虚拟模块工作与停止工作，即可实现目标功能的开启或关闭。
用户可以提前设置主ONT的目标功能是开启，还是关闭。可选的，用户可以通过终端设备，连接至主ONT，配置主ONT的目标功能是否开启，或者主ONT上设置有物理按钮，用户可以通过该物理按钮控制目标功能的开启与关闭。
主ONT可以检测目标功能是否开启，在检测到目标功能开启的情况下，确定组网模式为第一组网模式。第一组网模式也可以称为是分离组网模式、独立组网模式等。在检测到目标功能未开启的情况下，确定组网模式为第二组网模式，第二组网模式用于指示第一边缘ONT作为主ONT的扩展端口，扩展主ONT的无线信号。第二组网模式也可以称为是合一组网模式等。这样，可以准确的判断组网模式。
在一种可能的实现方式中，主ONT检测到组网模式为第一组网模式的情况下，该方法还包括：主ONT控制主ONT的供电功能关闭或者休眠。
其中，供电功能用于为至少一个边缘ONT供电。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
为了便于对本申请实施例的理解，下面首先介绍所涉及到的名词的概念：
1、PON，是一种无源光网络，通常由局端的OLT、ODN和ONT三部分组成，此处ONT也可以是光网络单元(optical network unit，ONU)。如图1所示，多个ONT通过ODN连接在同一个OLT的PON端口上。
2、FTTR，是将光纤不仅延伸至用户室内，还延伸至用户的各个房间中，在房间内部安装无线路由设备，这样，就缩小了用户的终端设备与无线路由设备的距离，保证了无线信号的质量。可选的，FTTR的一种组网方式可以为：如图2所示，网络运营商通过PON给用户提供千兆的接入带宽。家庭网关(即主ONT)可部署于信息箱内，光纤通过装修时预留的管孔资源连接到各个房间。家庭网关通过家庭内部部署的光纤与各个房间的ONT连接，各个房间ONT的无线信号只需要覆盖房间内部，家庭中的各个终端设备选择离自己最近的ONT进行连接。由于每个ONT需要覆盖的范围减小，多个ONT可以覆盖房间的每个角度。这样，基于FTTR的组网系统，用户的终端设备可以充分享受接入带宽提升带来的网络体验提升。
为了高效率的进行PON组网，本申请提供了一种PON的组网方法，该PON是二级组网，该PON包括主ONT和至少一个边缘ONT，该至少一个边缘ONT包括第一边缘ONT。例如，PON组网方法应用于FTTR中，主ONT为家庭网关，边缘ONT为各个房间中的ONT。本申请中涉及的ONT可以实现无线路由功能，不需要再接路由器，即可提供无线信号。
如下介绍边缘ONT的结构，如图3所示，边缘ONT可以包括存储器301和处理器302。存储器301可以是只读存储器(read only memory，ROM)，静态存储设备，动态存储设备或者随机存取存储器(random access memory，RAM)。存储器301可以存储计算机指令，当存储器301中存储的计算机指令被处理器302执行时，处理器302用于进行PON的组网方法。存储器301还可以存储数据。
处理器302可以采用通用的中央处理器(central processing unit，CPU)，微处理器，应用专用集成电路(application specific integrated circuit，ASIC)，图形处理器(graphics processing unit，GPU)或者一个或多个集成电路。
可选的，边缘ONT还可以包括通信接口和总线。其中，存储器301、处理器302、通信接口通过总线实现彼此之间的通信连接。通信接口使用例如但不限于收发器一类的收发模块，来实现边缘ONT与其他设备通信。例如，可以通过通信接口与主ONT进行通信。
总线可以包括在边缘ONT各个部件(例如，存储器301、处理器302、通信接口)之间传送信息的通路。
如下介绍主ONT的结构，如图4所示，主ONT可以包括存储器401和处理器402。存储器401可以是ROM，静态存储设备，动态存储设备或者RAM。存储器401可以存储计算机指令，当存储器401中存储的计算机指令被处理器402执行时，处理器402用于进行PON的组网方法。存储器401还可以存储数据。
处理器402可以采用通用的CPU，微处理器，ASIC，GPU或者一个或多个集成电路。
可选的，主ONT还可以包括通信接口和总线。其中，存储器401、处理器402、通信接口通过总线实现彼此之间的通信连接。通信接口使用例如但不限于收发器一类的收发模块，来实现主ONT与其他设备通信。例如，可以通过通信接口与边缘ONT进行通信。
总线可包括在主ONT各个部件(例如，存储器401、处理器402、通信接口)之间传送信息的通路。
如图5所示，PON的组网方法中边缘ONT的流程可以为：
步骤501，第一边缘ONT检测与主ONT的组网模式。
在本实施例中，第一边缘ONT在上电启动时，检测自己与主ONT的组网模式。或者第一边缘ONT在退出休眠模式时，检测自己与主ONT的组网模式。
在一种可能的实现方式中，步骤501中，第一边缘ONT可以按照以下方式，确定与主ONT的组网模式：
第一边缘ONT检测到不是由主ONT供电，且能接收到主ONT发送的下行报文，确定与主ONT的组网模式为第一组网模式；第一边缘ONT检测到由主ONT供电或者通过高速接口与主ONT连接，确定与主ONT的组网模式为第二组网模式。
其中，高速接口是第一边缘ONT的一种本地网络接口，用于与主ONT按照第二组网模式组网时，与主ONT连接。
在本实施例中，第一边缘ONT可以检测是否由主ONT供电，在检测到由主ONT供电时，可以确定组网模式为第二组网模式，在检测到不是由主ONT供电时，可以进一步判断是否接收到主ONT发送的下行报文，如果接收到主ONT发送的下行报文，确定组网模式为第一组网模式，反之如果未接收到主ONT发送的下行报文，则不可以确定组网模式为第一组网模式。或者第一边缘ONT可以检测是否通过高速接口与主ONT连接，在检测到通过高速接口与主ONT连接时，可以确定组网模式为第二组网模式。此处第一边缘ONT检测是否由主ONT供电，可以是检测与主ONT连接的输入电流模块是否开启，开启说明是由主ONT供电，否则说明不是由主ONT供电。
这样，可以基于供电情况准确的确定第一边缘ONT与主ONT的组网模式。
步骤502，在检测到与主ONT的组网模式为第一组网模式的情况下，第一边缘ONT接收主ONT下发的配置内容，基于该配置内容对第一边缘ONT进行配置。
其中，第一组网模式用于指示第一边缘ONT不是直接插在主ONT上，而是通过光纤、网线或无线中的一种或多种连接，连接至主ONT。第一组网模式也可以称为是分离组网模式、独立组网模式、单独组网模式等。
在本实施例中，第一边缘ONT在检测到与主ONT的组网模式为第一组网模式的情况下，第一边缘ONT接收主ONT下发的配置内容，然后使用该配置内容进行配置。
在一种可能的实现方式中，配置内容可以包括工作模式、业务配置或者网络配置中的一项或者多项，工作模式为桥接模式或路由模式，业务配置指示第一边缘ONT所进行的业务(如视频、语音、文本等)、网络配置指示第一边缘ONT的网络信息，如带宽等。第一边缘ONT将配置内容中的工作模式，配置为自身的工作模式，将配置内容中的业务配置，确定为第一边缘ONT所能进行的业务，使用配置内容中的网络配置，配置自身的网络。
另外，第一边缘ONT在检测到与主ONT的组网模式为第一组网模式的情况下，第一边缘 ONT也可以获取预先存储的配置内容，进行配置。例如，用户使用终端设备，通过与第一边缘ONT的网口或者无线方式连接至第一边缘ONT，在第一边缘ONT中配置了第一边缘ONT的工作模式为桥接模式，则第一边缘ONT将自身的工作模式配置为桥接模式。再例如，用户使用终端设备，通过与第一边缘ONT的网口或者无线方式连接至第一边缘ONT，在第一边缘ONT中配置了第一边缘ONT的工作模式为路由模式，则第一边缘ONT将自身的工作模式配置为路由模式，此时第一边缘ONT即为一个无线路由设备，用于为用户的终端设备提供无线信号。
在一种可能的实现方式中，步骤502中在第一边缘ONT的工作模式为路由模式的情况下，传输报文的过程可以为：
第一边缘ONT在接收到终端设备发送的第一上行报文时，将第一上行报文中的源IP地址转换为公网IP地址，将地址转换后的第一上行报文转发至主ONT；第一边缘ONT在接收到主ONT发送的第一下行报文时，将第一下行报文中的目的IP地址转换为私网IP地址，将地址转换后的第一下行报文转发至终端设备。
在本实施例中，第一边缘ONT处于路由模式下，即作为独立的无线路由设备使用，主ONT也作为独立的无线路由设备使用。
终端设备向外网发送上行报文(该上行报文称为是第一上行报文)的处理过程：终端设备在接入第一边缘ONT之后，终端设备向第一边缘ONT发送第一上行报文，第一上行报文中的源IP地址为终端设备的私网IP地址。第一边缘ONT在接收到第一上行报文时，第一边缘ONT可以将第一上行报文中的源IP地址转换为对应的公网IP地址。然后第一边缘ONT将转换后的第一上行报文转发至主ONT。主ONT可以对转换后的第一上行报文向外发送，发送至外网。或者主ONT可以对转换后的第一上行报文中的公网IP地址进行二次转换，转换为主ONT存储的公网IP地址，然后将二次转换后的第一上行报文向外发送，发送至外网。
终端设备接收外网发送的下行报文(该上行报文称为是第一下行报文)的处理过程：主ONT接收到外网发送的第一下行报文，主ONT可以将第一下行报文转发至第一边缘ONT，或者主ONT可以将第一下行报文中的目的IP地址转换为第一边缘ONT存储的公网IP地址，然后将地址转换后的第一下行报文转发至第一边缘ONT。第一边缘ONT可以将接收到的第一下行报文中的目的IP地址对应转换为对应的终端设备私网IP地址，将地址转换后的第一下行报文转发至终端设备。
步骤503，在检测到组网模式为第二组网模式的情况下，第一边缘ONT配置作为主ONT的桥接ONT或者进入休眠模式。
其中，第二组网模式用于指示第一边缘ONT直接插在主ONT上，指示第一边缘ONT作为主ONT的扩展端口，扩展主ONT的无线信号。第二组网模式也可以称为是合一组网模式、一体式组网模式等。
在本实施例中，第一边缘ONT在检测到组网模式为第二组网模式的情况下，用户使用终端设备，通过与第一边缘ONT的网口或者无线方式连接至第一边缘ONT，在第一边缘ONT中配置了第一边缘ONT的工作模式为桥接模式。第一边缘ONT将自身配置作为主ONT连接的桥接ONT。此时主ONT也是一个无线路由设备。
或者，第一边缘ONT在检测到组网模式为第二组网模式的情况下，用户使用终端设备，通过与第一边缘ONT的网口或者无线方式连接至第一边缘ONT，在第一边缘ONT中配置了第 一边缘ONT的工作模式为休眠模式。第一边缘ONT可以将自身设置为休眠模式，不进行任务业务处理。
可选的，第一边缘ONT处于第二组网模式的情况下，主ONT上设置有物理接口，第一边缘ONT是直接插在主ONT的该物理接口上。并且主ONT作为第一边缘ONT的电源，可以通过该物理接口为第一边缘ONT供电。
可选的，第一边缘ONT处于第二组网模式的情况下，用户可以使用终端设备，通过主ONT的网口或无线连接，连接至主ONT，在主ONT上对第一边缘ONT的带宽、进行的业务进行配置。在配置完成后，主ONT可以将用户对第一边缘ONT的配置内容，发送至第一边缘ONT。第一边缘ONT使用配置内容进行配置。当然也可以用户通过第一边缘ONT的网口或无线连接，连接至第一边缘ONT，对第一边缘ONT进行配置。
在一种可能的实现方式中，步骤503中第一边缘ONT设置作为主ONT的桥接ONT之后或者步骤502中第一边缘ONT的工作模式为桥接模式时，传输报文的流程可以为：
第一边缘ONT在接收到终端设备发送的第二上行报文时，将第二上行报文转发至主ONT；第一边缘ONT在接收到主ONT发送的第二下行报文时，将第二下行报文转发至终端设备。
在本实施例中，终端设备向外网发送上行报文(该上行报文称为是第二上行报文)的过程：终端设备在接入第一边缘ONT之后，终端设备向第一边缘ONT发送第二上行报文，第一边缘ONT不对第二上行报文进行处理，将接收到的第二上行报文发送至主ONT。如果主ONT与第一边缘ONT是二层桥接模式，则主ONT可以按照第二上行报文中的MAC地址，对第二上行报文进行转发，而不对第二上行报文进行处理。如果主ONT与第一边缘ONT是三层桥接模式，则主ONT将第二上行报文中的源IP地址，转换为对应的公网IP地址，然后将转换后的第二上行报文发送至外网。
终端设备接收外网发送的下行报文(该下行报文称为是第二下行报文)的过程：外网向主ONT发送第二下行报文，如果主ONT与第一边缘ONT是二层桥接模式，则主ONT可以按照第二下行报文中的MAC地址，将第二下行报文转发至第一边缘ONT。如果主ONT与第一边缘ONT是三层桥接模式，则主ONT将第二下行报文中的目的IP地址，转换为对应的终端设备的私网IP地址，然后将转换后的第二下行报文发送至第一边缘ONT。第一边缘ONT按照私网IP地址，将第二下行报文发送至私网IP地址指示的终端设备。
需要说明的是，如果主ONT与第一边缘ONT是三层桥接模式，则主ONT与第一边缘ONT所处的网段相同，处于一个局域网内。还需要说明的是，此处是以终端设备接入在第一边缘ONT的情况下进行说明，当然某些终端设备也可以直接接入至主ONT，此时传输报文不经过第一边缘ONT。
还需要说明的是，步骤502和步骤503没有先后顺序。
这样，第一边缘ONT可以自动的检测与主ONT的组网模式，并且设置自己的状态，而不需要人工设置，所以可以提升PON的组网效率。
本申请实施例，如图6所示，提供了PON的组网方法中主ONT的流程：
步骤601，主ONT检测组网模式。
在本实施例中，主ONT在启动后，检测自身的组网模式。
在一种可能的实现方式中，主ONT检测组网模式的处理可以为：
主ONT检测到目标功能开启，确定组网模式为第一组网模式；主ONT检测到目标功能未开启，确定组网模式为第二组网模式。
其中，目标功能为OLT功能，即管理边缘ONT的功能。目标功能在主ONT中对应有虚拟模块，控制该虚拟模块工作与停止工作，即可实现目标功能的开启或关闭。
在本实施例中，用户可以提前设置主ONT的目标功能是开启，还是关闭，具体的，用户可以通过终端设备，连接至主ONT，配置主ONT的目标功能是否开启，或者主ONT上设置有物理按钮，用户可以通过该物理按钮控制目标功能的开启与关闭。
主ONT可以检测目标功能是否开启，在检测到目标功能开启的情况下，确定组网模式为第一组网模式。第一组网模式也可以称为是分离组网模式、独立组网模式等。在检测到目标功能未开启的情况下，确定组网模式为第二组网模式，第二组网模式用于指示第一边缘ONT作为主ONT的扩展端口，扩展主ONT的无线信号。第二组网模式也可以称为是合一组网模式等。
步骤602，主ONT检测到组网模式为第一组网模式的情况下，向第一边缘ONT发送配置内容。
在本实施例中，主ONT在检测到组网模式为第一组网模式的情况下，可以对第一边缘ONT进行添加处理，在对第一边缘ONT添加成功后，可以向第一边缘ONT发送配置内容。配置内容可以包括工作模式、业务配置或者网络配置中的一项或者多项。
另外，主ONT控制自身的供电功能关闭或者休眠，该供电功能用于为PON中的至少一个边缘ONT供电，由于不需要对至少一个边缘ONT进行供电，所以将供电功能关闭或者休眠，可以降低主ONT的功耗。
步骤603，主ONT检测到组网模式为第二组网模式的情况下，为第一边缘ONT进行供电。
在本实施例中，主ONT检测到组网模式为第二组网模式的情况下，由于主ONT与第一边缘ONT直接相连，可以启动为边缘ONT供电的供电模块，为第一边缘ONT供电。
需要说明的是，步骤602和步骤603没有先后顺序。
这样，在图6的流程中，主ONT可以自动的检测组网模式，并且自动执行配置边缘ONT的处理，或者自动为边缘ONT供电，而不需要人工设置，所以可以提升PON的组网效率。
在一种可能的实现方式中，结合图5和图6的流程，PON中每个边缘ONT均是独立供电，与主ONT之间的连接可以为PON连接、P2P光纤连接、P2P网线连接或无线连接中的一种或多种。此时边缘ONT检测到与主ONT的组网模式为第一组网模式，每个边缘ONT均工作在桥接模式或者路由模式下。例如，如图7所示，PON中包括5个边缘ONT，5个边缘ONT为第一边缘ONT至第五边缘ONT，第一边缘ONT与第二边缘ONT通过1个1：2的分光器与主ONT实现PON连接，第三边缘ONT与主ONT通过P2P光纤连接，第四边缘ONT与主ONT通过P2P网线连接，第五边缘ONT与主ONT通过无线连接。
在一种可能的实现方式中，结合图5和图6的流程，主ONT上设置有多个物理接口，PON中每个边缘ONT是直接全部插在主ONT的不同物理接口上，均由主ONT供电。此时边缘ONT检测到与主ONT的组网模式为第二组网模式，每个边缘ONT均工作在桥接模式或者休眠模式下。例如，如图8所示，主ONT可以插入9个边缘ONT，PON中包括5个边缘ONT，5个边缘ONT为第一边缘ONT至第五边缘ONT，第一边缘ONT至第五边缘ONT均插在主ONT上，且工作 在桥接模式下。再例如，如图9所示，主ONT可以插入9个边缘ONT，PON中包括5个边缘ONT，5个边缘ONT为第一边缘ONT至第五边缘ONT，第一边缘ONT至第三边缘ONT均插在主ONT上，且工作在桥接模式下，第四边缘ONT和第五边缘ONT工作在休眠模式下。
在一种可能的实现方式中，PON中部分边缘ONT是独立供电，该部分边缘ONT工作在桥接模式或者路由模式下，其余边缘ONT是由主ONT供电，该其余边缘ONT工作在桥接模式下。
结合图5和图6的流程，还提供了一种PON，PON包括主ONT和至少一个边缘ONT，主ONT与至少一个边缘ONT相互配合，可以组成一体式的设备。主ONT与至少一个边缘ONT存在多种组网模式。可选的，多种组网模式可以包括第一组网模式和第二组网模式。
本申请实施例中，还提供了第一边缘ONT在检测到与主ONT的组网模式为第一组网模式的情况下，主ONT对第一边缘ONT进行认证和配置的处理流程，如图10所示：
步骤1001，主ONT广播发现消息，其中，发现消息包括第一标识信息，第一标识信息为主ONT的标识信息。
在本实施例中，主ONT在检测到组网模式为第一组网模式，且当前接入的边缘ONT的数目小于主ONT允许接入的最大边缘ONT数目，主ONT周期性广播发现消息，该发现消息包括第一标识信息，第一标识信息为主ONT的标识信息，第一标识信息可以是主ONT的设备序列号或者MAC地址等。当然在某些情况下，并不限制主ONT连接的边缘ONT的数目，所以在检测到组网模式为第一组网模式时，主ONT就可以一直周期性广播发现消息，直至检测到组网模式为第二组网模式。
另外，当前接入的边缘ONT的数目等于主ONT允许接入的最大边缘ONT数目之后，主ONT不再广播发现消息。当再次检测到已接入的边缘ONT的数目小于主ONT允许接入的最大边缘ONT数目，主ONT再次广播发现消息。
可选的，在主ONT可以通过所有向外发送消息的通路，向外广播发现消息。例如，该通路包括无线信号、PON端口和P2P端口等，PON端口表示是建立有PON连接，P2P端口表示建立有P2P光纤连接或者P2P网线连接。
步骤1002，第一边缘ONT接收主ONT广播的发现消息。
在本实施例中，第一边缘ONT接收主ONT广播的发现消息，从中获取第一标识信息。
可选的，第一边缘ONT可以通过在PON端口的接收方式、P2P端口的接收方式和无线信号接收方式中进行切换，确认是否接收主ONT广播的发现消息。
此处需要说明的是，在主ONT和第一边缘ONT的无线均开启时，二者可以通过无线信号进行通信；在主ONT和第一边缘ONT通过光纤连接时，二者可以通过PON或者P2P的方式进行通信；在主ONT和第一边缘ONT通过P2P网线连接时，二者可以通过P2P的方式进行通信。
步骤1003，第一边缘ONT在确定第一标识信息为存储的已知主ONT的标识信息后，向主ONT发送第二标识信息，其中，第二标识信息为第一边缘ONT的标识信息。
其中，第一边缘ONT中存储的已知主ONT的标识信息是可以接入的主ONT的标识信息，可以是在出厂时就存储在第一边缘ONT中。或者，第一边缘ONT中存储的已知主ONT的标识信息可以是用户通过终端设备连接第一边缘ONT后输入。已知主ONT的标识信息指示第一边缘ONT连接的主ONT。
在本实施例中，第一边缘ONT判断第一标识信息是否为存储的已知主ONT的标识信息，在确定第一标识信息为存储的已知主ONT的标识信息时，第一边缘ONT认为与主ONT是一个局域网的设备，第一边缘ONT可以获取自身的标识信息(即第二标识信息)，向主ONT发送第二标识信息。第二标识信息可以是第一边缘ONT的设备序列号或者MAC地址等。
可选的，如果第一边缘ONT至少通过PON连接接收到发现消息，则通过PON连接向主ONT发送第二标识信息。如果第一边缘ONT未通过PON连接接收到发现消息，而至少通过P2P光纤连接接收到发现消息，则通过P2P光纤连接向主ONT发送第二标识信息。如果第一边缘ONT未通过PON连接和P2P光纤连接接收到发现消息，而至少通过P2P网线连接接收到发现消息，则通过P2P网线连接向主ONT发送第二标识信息。如果第一边缘ONT仅通过无线连接接收到发现消息，则通过无线连接向主ONT发送第二标识信息。这样，由于PON连接更稳定，优先使用PON连接，可以使添加边缘ONT的过程的可靠性更高。
步骤1004，主ONT接收第一边缘ONT发送的第二标识信息。
步骤1005，在第二标识信息为存储的已知边缘ONT的标识信息的情况下，主ONT向第一边缘ONT发送配置内容。
其中，主ONT中存储的已知边缘ONT的标识信息是可以接入主ONT的边缘ONT的标识信息，可以是在出厂时就存储在主ONT中。或者，主ONT中存储的已知边缘ONT的标识信息可以是用户通过终端设备连接主ONT后输入。已知边缘ONT的标识信息指示允许接入主ONT的边缘ONT。
在本实施例中，主ONT接收到第二标识信息后，可以判断第二标识信息是否属于存储的已知边缘ONT的标识信息，在确定属于已知边缘ONT的标识信息后，认为是一个局域网的设备，可以向第一边缘ONT发送配置内容。具体的配置内容可以通过配置消息发送，配置消息可以是管理控制接口(optical network unit management and control interface，OMCI)消息。配置内容可以包括第一边缘ONT的业务配置(如视频、语音等)、网络配置(如使用的带宽)、第一边缘ONT的工作模式。此处进行的业务和使用的带宽可以是由用户预设配置在主ONT中。
步骤1006，第一边缘ONT接收主ONT在根据第二标识信息确定第一边缘ONT为已知边缘ONT后发送的配置内容。
步骤1007，第一边缘ONT使用配置内容，配置第一边缘ONT。
在本实施例中，第一边缘ONT接收到主ONT发送的配置内容后，可以将配置内容中的工作模式，配置为第一边缘ONT的工作模式。并且第一边缘ONT将配置内容中指示的业务、使用的带宽分别配置为第一边缘ONT可以进行的业务以及使用的带宽。在配置完成后，第一边缘ONT可以与主ONT进行业务报文的传输。
需要说明的是，在主ONT和第一边缘ONT之间的连接为PON连接时，主ONT与第一边缘ONT通过PON特有的数据帧格式进行交互。具体的，在PON为吉比特无源光网络(gigabit passive optical network，GPON)、10G对称吉比特无源光网络(10G symmetric passive optical network，XGS-PON)、10G非对称吉比特无源光网络(10G passive optical network，XG-PON)等更高速的PON时，步骤1001至步骤1004发送的报文使用物理层操作管理和维护(physical layer operations administration and maintenance，PLOAM)消息，步骤1005 和步骤1006发送的报文使用OMCI消息。在PON为以太网无源光网络(ethernet passive optical network，EPON)、10G EPON和25G EPON等更高速的EPON时，步骤1001至步骤1004发送的报文使用多点控制协议(multi-point control protocol，MPCP)消息，步骤1005和步骤1006发送的报文使用OMA消息。
在主ONT和第一边缘ONT之间的连接为P2P光纤连接或者P2P网线连接时，主ONT与第一边缘ONT通过普通的以太报文进行交互。
在主ONT和第一边缘ONT之间的连接为无线连接时，主ONT与第一边缘ONT通过802.11定义的通信方式进行连接进行交互。
这样，由于在边缘ONT添加至主ONT时，可以实现双向认证，防止其它非约定ONT接入，所以可以使PON的组网更安全。
需要说明的是，本申请实施例中，“至少一个”包括“一个”或“多个”两种情况。
