本发明涉及光通信领域，具体而言，涉及一种ONU的类型确定方法及装置、OLT、存储介质。The present invention relates to the field of optical communications, and in particular to a method and device for determining the type of an ONU, an OLT, and a storage medium.

背景技术Background technique

无源光网络设备根据工作机制可以分为基于以太网的无源光网络设备(Ethernet Passive Optical Network，简称EPON)、基于10G以太网的无源光网络设备(10G Ethernet Passive Optical Network，简称10GEPON)、千兆无源光网络设备(Gigabit-capable Passive Optical Network，简称G-PON)、NG无源光网络设备(N Gigabit-capable Passive Optical Network One，简称NG-PON1)以及其它工作机制的无源光网络设备(如10GEPON、10GPON、WDM-PON等)，其中，NG无源光网络设备是指NG-PON1类型的设备，分为两种，XGPON1和XGPON2，XGPON1是下行10Gbps/上行2.5Gbps的非对称***；XGPON2是上下行10Gbps的对称***。这些无源光网络设备***构架一致，均包含光线路终端(Optical Line Terminal，简称OLT)和光网络单元(Optical Network Unit，简称ONU)，以及光分配网络(Optical Distribution Network，简称ODN)。Passive optical network equipment can be divided into Ethernet-based passive optical network equipment (EPON) and 10G Ethernet passive optical network equipment (10G Ethernet Passive Optical Network, 10GEPON for short). , Gigabit-capable Passive Optical Network (G-PON), N Gigabit-capable Passive Optical Network One (NG-PON1) and other passive mechanisms Optical network equipment (such as 10GEPON, 10GPON, WDM-PON, etc.), wherein NG passive optical network equipment refers to NG-PON1 type equipment, which is divided into two types, XGPON1 and XGPON2, and XGPON1 is downlink 10Gbps/upstream 2.5Gbps. Asymmetric system; XGPON2 is a 10Gbps symmetric system for uplink and downlink. The systems of the passive optical network devices are identical in structure, and include an optical line terminal (OLT) and an optical network unit (ONU), and an optical distribution network (ODN).

无源光网络NG-PON1以及其他PON运行网络(简称xPON网络)中，常见组网***如图1所示，由OLT、光分配网络(Optical Distribution Network，简称ODN)和若干个ONU组成：OLT作为中心局端设备通过业务网络侧接口(Service Node Interface，简称SNI)实现业务向上层设备的转发，并通过ODN网络连接汇聚多个ONU设备，ONU设备通过用户网络侧接口(User Networks Interface，简称UNI)完成用户业务的最终接入，从而实现多种业务传输和配置管理等功能。NG-PON1网络作为“点对多点”的拓扑结构：从OLT到ONU的传输方向为下行方向(downstream)，下行方向采用广播方式(Broadcast)发送数据，由ONU根据数据标识判断数据是否有效并决定接收或丢弃；从ONU到OLT的传输方向为上行方向(upstream)，上行方向根据机制不同可以采用时分复用方式(Time Division Multiplexing)或波分复用方式(Wavelength Division Multiplexing)：在时分复用方式中，上行方向采用时分复用方式(Time Division Multiplexing)，ONU必须根据OLT分配的上行带宽时隙来发送上行突发(Burst)信号；在波分复用方式中，ONU上行数据承载于特定的工作波长中。在NG-PON1网络中，OLT的单个PON口通过唯一标识来区分并管理每个ONU，序列号SN(Serial Number)号是ONU的物理标识。通过物理标识完成ONU在PON***上的注册，并通过MAC地址、序列号(SN)、逻辑ONU标识(Logical ONU Identifier，简称LOID)以及密码(PW)等完成逻辑开通认证。In the passive optical network NG-PON1 and other PON operating networks (referred to as xPON networks), As shown in Figure 1, the common networking system consists of an OLT, an Optical Distribution Network (ODN), and a number of ONUs. The OLT is implemented as a central office equipment through a Service Node Interface (SNI). The service is forwarded to the upper-layer device, and the multiple ONU devices are aggregated through the ODN network. The ONU device completes the final access of the user service through the user network interface (User Network Interface, UNI for short), thereby implementing multiple service transmission and configuration management. And other functions. The NG-PON1 network serves as a "point-to-multipoint" topology: the transmission direction from the OLT to the ONU is downlink (downstream), and the downlink direction uses broadcast (Broadcast) to transmit data. The ONU determines whether the data is valid according to the data identifier. The transmission direction from the ONU to the OLT is the upstream direction (upstream), and the uplink direction can be time division multiplexing (Wavelength Division Multiplexing) or Wavelength Division Multiplexing (Wavelength Division Multiplexing) according to different mechanisms: time division multiplexing In the mode, the uplink direction uses Time Division Multiplexing. The ONU must send an uplink burst (Burst) signal according to the uplink bandwidth time slot allocated by the OLT. In the wavelength division multiplexing mode, the ONU uplink data is carried in the uplink mode. In a specific working wavelength. In the NG-PON1 network, a single PON port of the OLT distinguishes and manages each ONU by a unique identifier, and the serial number SN (Serial Number) is the physical identifier of the ONU. The registration of the ONU on the PON system is completed by physical identification, and the logical activation authentication is completed by a MAC address, a serial number (SN), a logical ONU identifier (LOID), and a password (PW).

相关技术中实现XGPON1和XGPON2在PON MAC上共存的方式包括：The manner in which the XGPON1 and XGPON2 coexist on the PON MAC in the related art includes:

1)OLT使得能够接入ONU从XGPON1切换到XGPON2，配置OLT模式之后必须重启OLT，这种方法操需要重新配置该OLT下所有的ONU，操作复杂，对其他ONU有业务影响，断网时间长。1) The OLT enables the ONU to switch from the XGPON1 to the XGPON2. After the OLT mode is configured, the OLT must be restarted. This method requires reconfiguration of all the ONUs in the OLT. The operation is complicated, and the service is affected by other ONUs. .

2)OLT使得能够接入ONU从XGPON1切换到XGPON2，配置线卡模式之后必须重启线卡，这种方法操需要重新配置该线卡下所有的ONU，对其他ONU有业务影响，断网时间长。2) The OLT enables access to the ONU to switch from XGPON1 to XGPON2, configuring the line card module After the type, the line card must be restarted. This method needs to reconfigure all the ONUs under the line card, which has business impact on other ONUs and has a long network disconnection time.

3)在光纤上添加WDM设备，达到多种ONU动态共存，如拓扑图2，这样做法，组网复杂，成本高。3) Add WDM equipment on the optical fiber to achieve dynamic coexistence of multiple ONUs, such as topology diagram 2. In this way, the networking is complicated and the cost is high.

本申请实施例可以运行于图1所示的网络架构上，如图1所示，该网络架构包括：光线路终端OLT、光分配网络ODN和多个光网络单元ONU，OLT通过ODN汇聚多个ONU设备。The embodiment of the present application can be run on the network architecture shown in FIG. 1, as shown in FIG. The network architecture includes: an optical line terminal OLT, an optical distribution network ODN, and a plurality of optical network units ONUs, and the OLT aggregates multiple ONU devices through the ODN.

在本实施例中提供了一种运行于上述光网络终端或网络架构的ONU的类型方法，图4是根据本发明实施例的ONU的类型方法的流程图，如图4所示，该流程包括如下步骤：In this embodiment, a method for operating an ONU of an optical network terminal or a network architecture is provided. FIG. 4 is a flowchart of a method for categorizing an ONU according to an embodiment of the present invention. As shown in FIG. 4, the process includes The following steps:

步骤S402，接收指定光网络单元ONU发送的数据；Step S402, receiving data sent by the designated optical network unit ONU;

步骤S404，确定用于传输数据的数据传输通道；Step S404, determining a data transmission channel for transmitting data;

步骤S406，根据数据传输通道与ONU类型的对应关系确定与数据传输通道对应的ONU类型；Step S406, determining an ONU type corresponding to the data transmission channel according to the correspondence between the data transmission channel and the ONU type;

步骤S408，将确定的ONU类型作为指定ONU的类型。Step S408, determining the determined ONU type as the type of the designated ONU.

通过上述步骤，由于通过不同的数据传输通道与ONU类型的对应关系，采用不同的数据传输通道识别不同的ONU类型，进而可以实现对不同的ONU采用不同的处理方式进行处理，进而实现了多个ONU的动态共存，可以实现多种类型的ONU随意接入和断开，而不需要OLT的重启、模式切换，或者OLT设备切换等，因此，可以解决无源光网络共存方式操作复杂的问题，减低了操作的复杂性。Through the above steps, different ONU types are identified by different data transmission channels by different data transmission channels and ONU types, and different ONUs can be processed by different processing modes, thereby implementing multiple The dynamic coexistence of ONUs enables multiple types of ONUs to be accessed and disconnected at will, without the need for OLT restart, mode switching, or OLT device switching. Therefore, the problem of complicated operation of the passive optical network coexistence mode can be solved. Reduce the complexity of the operation.

需要说明的是，上述数据传输通道可以有数据传输通道标记。即可以通过数据传输通道标记来确定上述数据的数据传输通道，但并不限于此。It should be noted that the above data transmission channel may have a data transmission channel mark. That is, the data transmission channel of the above data can be determined by the data transmission channel flag, but is not limited thereto.

在本发明的一个实施例中，在上述步骤S402之前，上述方法还可以包括：预先配置与至少一个ONU类型对应的至少一个数据传输通道，其中，至少一个数据传输通道中的每一个数据传输通道对应至少一个ONU类型中的一个ONU类型。In an embodiment of the present invention, before the step S402, the method may further include: pre-configuring at least one data transmission channel corresponding to the at least one ONU type, wherein each of the at least one data transmission channel Corresponds to one of the at least one ONU type.

需要说明的是，可以通过配置数据传输通道的方式有多种，比如可以根据不同的ONU类型所对应的参数来进行配置，比如以ONU类型对应的数据传输速率进行配置，在本发明的一个实施例中，预先配置与至少一个 ONU类型对应的至少一个数据传输通道可以表现为：通过至少一个ONU类型对应的数据传输速率分别配置至少一个数据传输通道。It should be noted that there are various ways of configuring the data transmission channel, for example, according to parameters corresponding to different ONU types, for example, configuring the data transmission rate corresponding to the ONU type, in an implementation of the present invention. In the example, pre-configured with at least one The at least one data transmission channel corresponding to the ONU type may be configured to: configure at least one data transmission channel by using a data transmission rate corresponding to the at least one ONU type.

需要说明的是，当至少一个ONU类型对应的多个OUN共存时，多个OUN上报的数据都可以进入上述至少一个数据传输通道中，但是该数据传输通道只允许与该数据传输通道对应的那个ONU类型的ONU上报的数据通过，其他ONU类型对应的ONU上报的数据将在该数据传输通道中被丢弃。It should be noted that, when multiple OUNs corresponding to at least one ONU type coexist, data reported by multiple OUNs may enter the at least one data transmission channel, but the data transmission channel only allows the one corresponding to the data transmission channel. The data reported by the ONU of the ONU type is passed, and the data reported by the ONU corresponding to the other ONU type is discarded in the data transmission channel.

以两个ONU类型，其两个ONU的类型分别为XGPON1和XGPON2为例进行说明，由于XGPON1的上行传输速率为2.5Gbps,XGPON2为10Gbps,，因而根据这两个速度的差异来配置两个具有不同数据传输速率的数据传输通道，比如数据传输通道1的数据传输速率设置为2.5Gbps，而数据传输通道2的数据传输速率为10Gbps，在该情况下，数据传输通道1只允许数据传输速率为2.5Gbps的数据通过，数据传输通道2只允许数据传输速率为10Gbps的数据通过，因而配置的两个数据传输通道与上述两个ONU的类型的对应关系可以理解为：数据传输通道1与XGPON1类型的ONU1对应，数据传输通道2与XGPON2类型的ONU2对应，即数据传输通道1只能允许上述XGPON1类型的ONU1上报的数据，数据传输通道2只能允许上述XGPON2类型的ONU2上报的数据。需要说明的是，当上述ONU1和ONU2共存时，上述ONU1上报的数据和上述ONU2上报的数据都会进入到上述数据传输通道1和数据传输通道2中，但ONU1上报的数据可以成功通过数据传输通道1，而ONU2上报的数据在数据传输通道1内被丢弃，同样，ONU2上报的数据可以成功通过数据传输通道2，而ONU1上报的数据在数据传输通道2内被丢弃。In the case of two ONU types, the types of the two ONUs are XGPON1 and XGPON2 respectively. Since the uplink transmission rate of XGPON1 is 2.5 Gbps and XGPON2 is 10 Gbps, two of the two speeds are configured according to the difference between the two speeds. The data transmission channel with different data transmission rates, such as the data transmission rate of the data transmission channel 1 is set to 2.5 Gbps, and the data transmission rate of the data transmission channel 2 is 10 Gbps. In this case, the data transmission channel 1 only allows the data transmission rate to be The 2.5 Gbps data is passed, and the data transmission channel 2 only allows data with a data transmission rate of 10 Gbps to pass. Therefore, the correspondence between the two data transmission channels configured and the types of the two ONUs can be understood as: data transmission channel 1 and XGPON1 type. The data transmission channel 2 corresponds to the ONU2 of the XGPON2 type, that is, the data transmission channel 1 can only allow the data reported by the ONU1 of the XGPON1 type, and the data transmission channel 2 can only allow the data reported by the XGPON2 type ONU2. It should be noted that, when the ONU1 and the ONU2 coexist, the data reported by the ONU1 and the data reported by the ONU2 enter the data transmission channel 1 and the data transmission channel 2, but the data reported by the ONU1 can successfully pass through the data transmission channel. The data reported by the ONU2 is discarded in the data transmission channel 1. Similarly, the data reported by the ONU2 can successfully pass through the data transmission channel 2, and the data reported by the ONU1 is discarded in the data transmission channel 2.

通过上述步骤，可以使得不同类型的ONU分别使用各自独立的数据传输通道，进而不需要重新配置OLT类型去支持不同类型的ONU，更不需要根据类型去区分不同的OLT，因而可以给组网带来更好的灵活性，使得设备上可以根据不同的客户群规划不同的网络拓扑结构，大大降低了组网成本，降低了运维的成本。Through the above steps, different types of ONUs can be used to independently use different data transmission channels, thereby eliminating the need to reconfigure the OLT type to support different types of ONUs, and more unnecessary Different types of OLTs can be distinguished according to the type, so that the networking can be more flexible, so that different network topologies can be planned according to different customer groups, which greatly reduces the networking cost and reduces the operation and maintenance cost. .

在本发明的一个实施例中，在上述步骤S408之后，上述方法还可以包括：将与指定ONU的类型对应的数据传输速率写入物理层操作维护管理PLOAM消息中。In an embodiment of the present invention, after the step S408, the method may further include: writing a data transmission rate corresponding to the type of the specified ONU into the physical layer operation and maintenance management PLOAM message.

需要说明的是，将该数据传输速率写入上述PLOAM消息，进而可以使得OLT的驱动软件获取到PLOAM消息后，分析ONU类型字段后，该驱动软件记录下ONU类型，进而识别出了当前的ONU类型。通过上述步骤，可以使得，OLT设备的软件部分获取到ONU类型后，可以根据不用的ONU类型做相应的认证、注册和建立数据业务，同时，屏蔽了多种ONU的具体配置细节，命令行配置相同，进而节省了操作的复杂度。It should be noted that the data transmission rate is written into the PLOAM message, and then the driver software of the OLT obtains the PLOAM message, and after analyzing the ONU type field, the driver software records the ONU type, thereby identifying the current ONU. Types of. Through the above steps, after the software part of the OLT device obtains the ONU type, it can perform corresponding authentication, registration, and data service according to the unused ONU type.

为了更好地理解本发明，以下结合优选的实施例对本发明做进一步解释。For a better understanding of the invention, the invention is further explained in conjunction with the preferred embodiments.

本发明优选实施例提供了一种实现多种ONU动态共存的方法，以下以XGPOIN1和XGPON2在PON MAC上动态共存为例进行说明。A preferred embodiment of the present invention provides a method for implementing dynamic coexistence of multiple ONUs. The following describes an example in which XGPOIN1 and XGPON2 dynamically coexist on a PON MAC.

本发明提出了在一个无源光网络中，OLT设备的PON MAC芯片设计两个不同的数据接收通道(相当于上述实施例中的数据传输通道)区分接入ONU类型是XGPON1或XGPON2，如图5所示，RX是接收通道标记，RX1和RX2分别是两个通道的标记，当OLT给ONU分配带宽后，XGPON1 或XGPON2类型的ONU上报的数据都能进入RX1和RX2两个通道，但是这两个通道的速率有差异(XGPON1为2.5Gbs，XGPON2为10Gbs)，XGPON2的数据在RX1的通道内被PON MAC丢弃，同理XGPON1的数据在RX2的通道内会丢弃。这种方法使得两个不同类型的ONU分别使用各自独立的数据接收通道，这两个数据接收通道可以按照一定的时序传输数据，当PON MAC识别ONU的类型之后，在相应的寄存器设置ONU的类型，PON MAC驱动程序可以从寄存器中动态获取接入ONU的类型是XGPON1或是XGPON2，驱动程序和业务层软件可以按照上报的ONU类型做认证，注册，建立数据业务，从而实现在一种XGPON1和XGPON2在PON MAC上动态共存的实现方法。The present invention proposes that in a passive optical network, the PON MAC chip of the OLT device is designed with two different data receiving channels (corresponding to the data transmission channel in the above embodiment). The differentiated access ONU type is XGPON1 or XGPON2, as shown in the figure. As shown in Figure 5, RX is the receiving channel mark, and RX1 and RX2 are the marks of the two channels respectively. When the OLT allocates bandwidth to the ONU, XGPON1 The data reported by the XGPON2 type ONU can enter the RX1 and RX2 channels, but the rates of the two channels are different (2.5Gbs for XGPON1 and 10Gbs for XGPON2), and the data of XGPON2 is discarded by the PON MAC in the channel of RX1. Similarly, the data of XGPON1 will be discarded in the channel of RX2. This method allows two different types of ONUs to use separate data receiving channels, and the two data receiving channels can transmit data according to a certain timing. After the PON MAC recognizes the type of the ONU, the type of the ONU is set in the corresponding register. The PON MAC driver can dynamically obtain the type of access ONU from the register is XGPON1 or XGPON2. The driver and service layer software can perform authentication, registration, and establishment of data services according to the reported ONU type, thereby implementing an XGPON1 and The implementation method of XGPON2 dynamically coexisting on PON MAC.

XGPON1和XGPON2在PON MAC上动态共存的实现方法和过程，可以包括如下操作：The implementation method and process of dynamically coexisting XGPON1 and XGPON2 on the PON MAC may include the following operations:

在OLT设备成功注册一个ONU，OLT首先给ONU分配带宽，XGPON1或XGPON2上的ONU获得带宽后，通过RX通道上报自己的注册信息，由于XGPON1类型的ONU上行最大带宽是2.5Gbps,XGPON2类型的ONU上行最大带宽是10Gbps，两种不同类型的ONU在PON MAC使用不同的数据通道，XGPON1类型的ONU上行数据成功通过RX1通道后，PON MAC芯片把这个ONU速率特性(数据传输速率)写入PLOAM消息字段，OLT的PON MAC驱动软件获取PLOAM消息后，分析ONU类型字段，PON MAC驱动软件记录下该ONU类型，OLT识别了当前的ONU类型。After the OLT device successfully registers an ONU, the OLT first allocates bandwidth to the ONU. After the ONU on the XGPON1 or XGPON2 obtains the bandwidth, the OLT reports its own registration information through the RX channel. The maximum bandwidth of the ONU uplink of the XGPON1 type is 2.5 Gbps, and the ONU of the XGPON2 type The maximum uplink bandwidth is 10 Gbps. Two different types of ONUs use different data channels in the PON MAC. After the uplink data of the XGPON1 type ONU successfully passes through the RX1 channel, the PON MAC chip writes the ONU rate characteristic (data transmission rate) into the PLOAM message. In the field, after the PON MAC driver software of the OLT acquires the PLOAM message, the ONU type field is analyzed, the PON MAC driver software records the ONU type, and the OLT identifies the current ONU type.

然后在测距，带宽配置时，带上带宽参数，相关技术中的处理方式是XGPON2需要带上带宽10Gbps参数，XGPON1带上ONU类型带宽2.5Gbps参数。这样两种不同类型的ONU通过使用不同配置这方法在硬件和驱动软件区别开来，之后建立OMCI(ONU Management and Control Interface)通道，完成注册，在OLT设备应用层软件屏蔽了两种ONU的具体配置细节，命令行配置相同，这样操作简单。Then, in the ranging and bandwidth configuration, the bandwidth parameter is adopted. The processing method in the related art is that XGPON2 needs to bring a bandwidth of 10 Gbps parameter, and XGPON1 carries an ONU type bandwidth of 2.5 Gbps parameter. The two different types of ONUs are distinguished between the hardware and the driver software by using different configurations. After that, the OMCI (ONU Management and Control Interface) channel is established, and the registration is completed. The application layer software of the OLT device shields the specificities of the two ONUs. Configuration details, The command line configuration is the same, which is easy to use.

两种不同类型的ONU在OLT设备上成功注册后，皆可以根据客户的需要配置，建立Tcont，GemPort，VLAN等各种不同的数据业务，这样就达到了XGPON1和XGPON2在PON MAC上动态共存的实现方法。After the two types of ONUs are successfully registered on the OLT device, they can be configured according to the needs of the customer, and establish various data services such as Tcont, GemPort, and VLAN. This achieves the dynamic coexistence of XGPON1 and XGPON2 on the PON MAC. Implementation.

采用本优选实施例提供的上述技术问题，通过OLT设备PON MAC设计不同的通道去区分不同的ONU类型，OLT设备PON MAC软件动态获取ONU类型，根据不同的ONU类型做相应的认证，注册，建立数据业务，同时OLT设备软件屏蔽了两种ONU的具体配置细节，命令行操作简单，组网灵活，维护简单，节省成本，方便客户任意接入和断开XGPON1和XGPON2类型的ONU，而不需要进行OLT的重启，模式切换，OLT设备切换，这样既符合xPON网络运营者的运维需求，也符合终端用户的利益需求。With the above technical problem provided by the preferred embodiment, the PON device PON MAC design different channels to distinguish different ONU types, and the PON device PON MAC software dynamically acquires the ONU type, and performs corresponding authentication, registration, and establishment according to different ONU types. Data service, while the OLT device software shields the specific configuration details of the two ONUs. The command line is simple to operate, flexible in networking, simple in maintenance, and cost-effective. It is convenient for customers to access and disconnect XGPON1 and XGPON2 type ONUs without the need. The OLT is restarted, the mode is switched, and the OLT device is switched. This is in line with the operation and maintenance requirements of the xPON network operator and the end user's interests.

OLT的软件根据PON MAC芯片设计不同通道的方式的识别不同类型的ONU后，然后OLT软件不同类型的ONU采用不同的注册方式，使得他们动态共存，任意接入和断开。The software of the OLT recognizes different types of ONUs according to the way of designing different channels of the PON MAC chip, and then the different types of ONUs of the OLT software adopt different registration modes, so that they coexist dynamically, arbitrarily access and disconnect.

需要说明的是，在PON MAC芯片可以继续增加通道方式，使得GPON，XGPON1,XGPON2和NG-PON2可以动态共存，OLT的驱动软件不需要做很大的修改，即可以实现。同理EPON和XEPON也可以用这种方法实现动态共存。It should be noted that the PON MAC chip can continue to increase the channel mode, so that GPON, XGPON1, XGPON2 and NG-PON2 can coexist dynamically, and the OLT driver software can be realized without major modification. Similarly, EPON and XEPON can also achieve dynamic coexistence in this way.

图6是根据本发明优选实施例提供的方法的流程示意图，该图6所示：6 is a schematic flow chart of a method according to a preferred embodiment of the present invention, and FIG. 6 is as follows:

考虑在NGPON1(XGPON1和XGPON2)网络中按照本发明优选实例提供的方法的一种实施范例，OLT与XGPON1和XGPON2终端设备ONU之间实现动态共存，包括如下步骤：Considering an implementation of the method provided by the preferred embodiment of the present invention in the NGPON1 (XGPON1 and XGPON2) network, the dynamic coexistence between the OLT and the XGPON1 and the XGPON2 terminal device ONU includes the following steps:

S601：OLT启动ONU发现流程，针对每个PON口确认是否有新的ONU上线。 S601: The OLT starts the ONU discovery process, and determines whether a new ONU is online for each PON port.

若为已经注册认证过的ONU标识(SN在映射表中已经存在)，则直接注册成功，并按原有数据进行业务配置和开通；若PON口未包含相应标识信息，则认为是新的ONU。If it is an already registered ONU identifier (the SN already exists in the mapping table), the direct registration is successful, and the service is configured and opened according to the original data; if the PON interface does not contain the corresponding identification information, it is considered to be a new ONU. .

S602：ONU上报SN，OLT设备的PON MAC芯片根据ONU上行的通道不一样，识别ONU的类型，XGPON1或是XGPON2的ONU，设置在寄存器中。S602: The ONU reports the SN, and the PON MAC chip of the OLT device identifies the type of the ONU according to the uplink channel of the ONU, and the ONU of the XGPON1 or the XGPON2 is set in the register.

S603：OLT设备软件获取ONU的类型，把ONU的类型记录下来，在带宽分配，Tcont配置的时候带上了ONU的类型。后续完成测距，OMCI通道建立，ONU认证注册成功。S603: The OLT device software acquires the type of the ONU, records the type of the ONU, and carries the type of the ONU when the bandwidth is allocated and the Tcont is configured. After the completion of the ranging, the OMCI channel is established, and the ONU authentication is successfully registered.

本发明优选实施例提出的XGPON1和XGPON2在PON MAC上动态共存的方法，是指OLT设备上，同时通过ODN设备在同一PON口下接入XGPON1和XGPON2类型的ONU，PON口上的光模块只需要普通的XGPON的光模块，不需要改进，也不需要外加其他设备，OLT设备PON MAC可以根据接入的ONU类型不同采用不同的处理方法，使得两种不同类型的ONU可以共存，同时工作，同时后续接入的XGPON1和XGPON2类型的ONU没有任何类型限制，可以随意接入和断开，同时参见图6中，步骤S604，OLT设备软件屏蔽了XGPON1和XGPON2两种ONU，配置用于数据传输的Tcont，GemPort，VLAN等等数据。如此，通过屏蔽两种ONU的具体配置细节，命令行操作简单。The method for dynamically coexisting the XGPON1 and the XGPON2 on the PON MAC according to the preferred embodiment of the present invention means that the optical module on the PON port is only required to be connected to the ONU of the XGPON1 and the XGPON2 under the same PON interface through the ODN device. Ordinary XGPON optical modules do not need to be improved, and no other equipment is required. The PON MAC of the OLT device can adopt different processing methods according to different types of ONUs that are accessed, so that two different types of ONUs can coexist and work simultaneously. The subsequent accesses of the XGPON1 and XGPON2 type ONUs do not have any type restrictions and can be accessed and disconnected at will. Referring to FIG. 6, in step S604, the OLT device software shields the XGPON1 and XGPON2 ONUs and configures them for data transmission. Tcont, GemPort, VLAN, etc. Thus, by shielding the specific configuration details of the two ONUs, the command line operation is simple.

本发明优选实施例提出的方案使得PON MAC有更好的兼容性，不需要重新配置OLT类型去支持XGPON1或是XGPON2类型的ONU，更不需要根据XGPON1和XGPON2类型的ONU去区分不同的OLT。这种设计给组网带来更好的灵活性，使得设备商可以根据不同的客户群规划不同的网络拓扑结构，大大降低组网成本，降低运维成本。另外，随着PON网络的发展，不同类型种ONU设备在OLT设备PON MAC上动态共存将会成为一种很重要的组网形态，可以作为家庭网关、移动终端设备以及企业网关等用户组网方式，来推动FTTx市场的进一步发展，前景广阔。The solution proposed by the preferred embodiment of the present invention makes the PON MAC have better compatibility, and does not need to reconfigure the OLT type to support the XGPON1 or the XGPON2 type ONU, and does not need to distinguish different OLTs according to the ONGs of the XGPON1 and XGPON2 types. This design brings more flexibility to the networking, enabling equipment vendors to plan different network topologies according to different customer groups, greatly reducing networking costs and reducing operation and maintenance costs. In addition, with the development of PON networks, the dynamic coexistence of different types of ONU devices on the PON MAC of OLT devices will become A very important networking form can be used as a user gateway for home gateways, mobile terminal devices, and enterprise gateways to promote the further development of the FTTx market with broad prospects.

综上所述，本发明优选实施例采用的一种XGPON1和XGPON2在PON MAC上动态共存的实现方法，对于灵活组网，大大降低组网成本将在实际工程中的发挥重要作用。In summary, the implementation method of dynamically coexisting XGPON1 and XGPON2 on the PON MAC adopted by the preferred embodiment of the present invention, for flexible networking, greatly reducing the networking cost will play an important role in the actual project.
