One physical OLT can be virtualized into multiple virtual optical line terminals (vOLT, virtual Optical Line Terminal), so that the physical OLT can be used as an open hardware platform. Multiple vOLTs share the hardware resources of the same physical OLT and can realize dynamic resources Allocation can help simplify the network structure, shorten service deployment time, realize resource sharing between departments or operators, and can also save physical hardware resource costs.

但是，ONU注册到vOLT的过程较为复杂，运维难度较大，注册管理效率也较低。However, the process of ONU registration to vOLT is relatively complicated, operation and maintenance is difficult, and registration management efficiency is low.

具体实施方式Detailed ways

为使本领域的技术人员更好地理解本公开的技术方案，下面结合附图对本公开提供的光网络单元的注册方法、光线路终端、光网络单元、计算机可读存储介质进行详细描述。In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the registration method of the optical network unit, the optical line terminal, the optical network unit, and the computer-readable storage medium provided by the present disclosure are described in detail below in conjunction with the accompanying drawings.

在下文中将参考附图更充分地描述示例实施例，但是所述示例实施例可以以不同形式来体现，且本公开不应当被解释为限于本文阐述的实施例。提供这些实施例的目的在于使本公开更加透彻和完整，并使本领域技术人员充分理解本公开的范围。Example embodiments will be described more fully below with reference to the accompanying drawings, although they may be embodied in different forms and the disclosure should not be construed as limited to the embodiments set forth herein.

如本文所使用的，术语“和/或”包括一个或多个相关列举条目的任何和所有组合。As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

本文所使用的术语仅用于描述特定实施例，且不限制本公开。如本文所使用的，单数形式“一个”和“该”也包括复数形式，除非上下文另外清楚指出。还将理解的是，当本说明书中使用术语“包括”和/或“由……制成”时，指定存在特定特征、整体、步骤、操作、元件和/或组件，但不排除存在或可添加一个或多个其它特征、整体、步骤、操作、元件、组件和/或其群组。The terminology used herein is used to describe particular embodiments only and does not limit the disclosure. As used herein, the singular forms "a," "an" and "the" also include the plural forms unless the context clearly dictates otherwise. It will also be understood that when the terms "comprising" and/or "made of" are used in this specification, it is specified that particular features, integers, steps, operations, elements and/or components are present but not excluded. Add one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

除非另外限定，否则本文所用的所有术语(包括技术术语和科学术语)的含义与本领域普通技术人员通常理解的含义相同。还将理解，诸如在常用字典中限定的那些术语应当被解释为具有与其在相关技术以及本公开的背景下的含义一致的含义，且不解释为具有理想化或过度形式上的含义，除非本文明确如此限定。Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. will also understand, Terms such as those defined in commonly used dictionaries should be construed to have meanings consistent with their meanings in the context of the relevant art and the present disclosure, and not to have idealized or excessive formal meanings unless expressly so defined herein.

在一些相关技术中，ONU的发现注册机制包括：未注册的ONU将自己的序列号(SN,Serial Number)发送给OLT，OLT接收未注册的ONU的序列号并加入到其未注册ONU列表，OLT运维人员可以根据未注册ONU列表向未注册的ONU下发ONU注册命令，完成ONU注册管理。在一个物理OLT虚拟成多个vOLT、并且多个vOLT共享同一个物理PON口的场景中，当一个新的ONU连接到该物理PON口时，无法自动判断这个新的ONU应该归属到哪个vOLT来注册管理，共享该物理PON口的所有vOLT都可以发现到这个新的ONU，并可以将这个新的ONU的序列号加入自己的未注册ONU列表，从而导致运维人员可能将不属于自己的ONU注册到自己管理的vOLT上，引发运维异常。In some related technologies, the ONU discovery and registration mechanism includes: an unregistered ONU sends its serial number (SN, Serial Number) to the OLT, and the OLT receives the serial number of the unregistered ONU and adds it to its unregistered ONU list. OLT operation and maintenance personnel can issue ONU registration commands to unregistered ONUs based on the unregistered ONU list to complete ONU registration management. In a scenario where a physical OLT is virtualized into multiple vOLTs and multiple vOLTs share the same physical PON port, when a new ONU is connected to the physical PON port, it is impossible to automatically determine which vOLT the new ONU should belong to. Registration management, all vOLTs sharing the physical PON port can discover this new ONU, and can add the serial number of this new ONU to their own unregistered ONU list, which may cause operation and maintenance personnel to use ONUs that do not belong to them. Registered to the vOLT managed by oneself, causing operation and maintenance exception.

为了规避上述问题，一个解决方案是从ONU的角度，事先规划好每一个新接入的ONU归属于哪一个vOLT,具体实现是以手工配置的方式，人工指定某个序列号的ONU只能被某一个vOLT发现。但是，该解决方案依赖于运维人员进行人工配置，且需要事先知晓每个ONU的序列号或ONU的序列号的号段，但是ONU的序列号数量较大，特别是当ONU的序列号无规律时，人工配置操作困难，严重影响ONU注册管理效率；此外，在ONU注册过程中，运维人员还是可能操作非归属于自己的终端，例如将非归属于自己的ONU注册到自己的vOLT，容易导致不同vOLT之间信息泄露。In order to avoid the above problems, one solution is to plan in advance which vOLT each newly connected ONU belongs to from the perspective of the ONU. The specific implementation is to manually configure the ONU with a certain serial number. A certain vOLT was discovered. However, this solution relies on manual configuration by operation and maintenance personnel, and needs to know the serial number of each ONU or the number segment of the ONU serial number in advance. However, the number of ONU serial numbers is large, especially when the ONU serial number does not exist. In regular conditions, manual configuration operations are difficult, seriously affecting the efficiency of ONU registration management; in addition, during the ONU registration process, operation and maintenance personnel may still operate terminals that do not belong to themselves, such as registering ONUs that do not belong to themselves to their own vOLT. It is easy to cause information leakage between different vOLTs.

第一方面，参照图1，本公开实施例提供一种ONU的注册方法，应用于配置有至少一个vOLT的光线路终端OLT，所述注册方法包括S11和S12。In the first aspect, referring to FIG. 1 , an embodiment of the present disclosure provides an ONU registration method, which is applied to an optical line terminal OLT configured with at least one vOLT. The registration method includes S11 and S12.

S11、当任意一个所述vOLT获取到ONU的注册消息时，对所述注册消息携带的虚拟光线路终端标签的内容进行校验，所述虚拟光线路终端标签用于标注所述ONU归属的vOLT的标识。S11. When any of the vOLTs obtains the registration message of the ONU, verify the content of the virtual optical line terminal label carried in the registration message. The virtual optical line terminal label is used to mark the vOLT to which the ONU belongs. logo.

S12、在所述虚拟光线路终端标签的内容与当前的所述vOLT的标识一致的情况下，将所述ONU注册到当前的所述vOLT上。 S12. If the content of the virtual optical line terminal tag is consistent with the identification of the current vOLT, register the ONU to the current vOLT.

在本公开实施例中，一个物理的OLT可以虚拟成一个或多个vOLT，不同vOLT的标识不同。In this embodiment of the present disclosure, a physical OLT can be virtualized into one or more vOLTs, and different vOLTs have different identities.

在本公开实施例提供的ONU的注册方法中，OLT可以包括由多个vOLT共享的共享物理端口，也可以包括非共享物理端口，还可以同时包括共享物理端口和非共享物理端口。本公开实施例对此不做特殊限定。在一些实施方式中，物理端口为PON端口。相应地，注册消息可以是vOLT从共享物理端口获取的，也可以是vOLT从非共享物理端口获取的。本公开实施例对此也不做特殊限定。In the ONU registration method provided by the embodiment of the present disclosure, the OLT may include a shared physical port shared by multiple vOLTs, may also include a non-shared physical port, or may include both a shared physical port and a non-shared physical port. The embodiments of the present disclosure do not impose special limitations on this. In some implementations, the physical port is a PON port. Correspondingly, the registration message can be obtained by the vOLT from a shared physical port, or it can be obtained by the vOLT from a non-shared physical port. The embodiment of the present disclosure does not impose any special limitations on this.

本公开实施例提供的ONU的注册方法中，ONU向OLT发送注册消息，在注册消息中携带标注了ONU归属的vOLT的标识的虚拟光线路终端标签(vOLT标签)，OLT中配置的各个vOLT获取到注册消息后对虚拟光线路终端标签的内容进行校验，通过判断虚拟光线路终端标签的内容与vOLT的标识是否一致确定ONU的归属，只有标识与虚拟光线路终端标签的内容一致的vOLT才对注册消息进行处理。在ONU注册过程中，vOLT能够直接识别所属的ONU，提高了ONU注册管理的便捷性；vOLT只对所属的ONU进行注册，避免了不同vOLT之间的信息泄露，提升了信息安全性；此外，由于OLT中配置的vOLT数量有限，且vOLT的标识通常是具有规律的，根据vOLT的标识确定ONU的归属，比起根据ONU的序列号确定ONU的归属更加容易，进一步提高了ONU注册管理的便捷性，提升了ONU注册管理效率。In the ONU registration method provided by the embodiment of the present disclosure, the ONU sends a registration message to the OLT. The registration message carries a virtual optical line terminal label (vOLT label) marked with the identity of the vOLT to which the ONU belongs. Each vOLT configured in the OLT obtains After receiving the registration message, the content of the virtual optical line terminal label is verified, and the ownership of the ONU is determined by judging whether the content of the virtual optical line terminal label is consistent with the identity of the vOLT. Only the vOLT whose identity is consistent with the content of the virtual optical line terminal label can be Process registration messages. During the ONU registration process, vOLT can directly identify the ONU it belongs to, which improves the convenience of ONU registration management; vOLT only registers the ONU it belongs to, avoiding information leakage between different vOLTs and improving information security; in addition, Since the number of vOLTs configured in the OLT is limited, and the identification of vOLTs is usually regular, it is easier to determine the ownership of an ONU based on the identification of vOLTs than based on the serial number of the ONU, further improving the convenience of ONU registration and management. It improves the efficiency of ONU registration management.

在一些实施方式中，如图2所示，OLT中存在由多个vOLT共享的共享物理端口。ONU可以通过共享物理端口接入OLT，也可以通过非共享的物理端口接入OLT。本公开实施例对此不做特殊限定。图2中仅示出了ONU通过一个共享物理端口与多个vOLT连接的场景。相应地，在本公开实施例中，注册消息可以是由多个vOLT共享的共享物理端口接收的，也可以是通过非共享的物理端口接收的。也就是说，在本公开实施例中，vOLT可以只对从共享物理端口接收的注册消息的虚拟光线路终端标签的内容进行校验，对于从非共享物理端口接收的注册消息，则不进行校验；此外，在一些实施方式中，可以是一个vOLT对应有多个物理端口，多个物理端口可以包含共享物理端口和非共享物理端口，vOLT也可以对从共享物理端口接收的注册消息和从非共享物理端口接收的注册消息的虚拟光线路终端标签的内容都进行校验。本公开实施例对此不做特殊限定。In some implementations, as shown in Figure 2, there is a shared physical port in the OLT that is shared by multiple vOLTs. The ONU can access the OLT through a shared physical port, or it can access the OLT through a non-shared physical port. The embodiments of the present disclosure do not impose special limitations on this. Figure 2 only shows the scenario where an ONU is connected to multiple vOLTs through a shared physical port. Correspondingly, in the embodiment of the present disclosure, the registration message may be received through a shared physical port shared by multiple vOLTs, or may be received through a non-shared physical port. That is to say, in the embodiment of the present disclosure, the vOLT can only verify the content of the virtual optical line terminal label of the registration message received from the shared physical port, and does not verify the registration message received from the non-shared physical port. In addition, in some implementations, one vOLT may correspond to multiple physical ports, and the multiple physical ports may include shared physical ports and For non-shared physical ports, vOLT can also verify the contents of the virtual optical line terminal tag of the registration message received from the shared physical port and the registration message received from the non-shared physical port. The embodiments of the present disclosure do not impose special limitations on this.

相应地，在一些实施方式中，参照图3，所述对所述注册消息携带的虚拟光线路终端标签的内容进行校验包括S111和S112。Accordingly, in some implementations, referring to FIG. 3 , the verification of the content of the virtual optical line terminal label carried in the registration message includes S111 and S112.

S111、判断所述注册消息是否接收自共享物理端口，多个所述虚拟光线路终端共享所述共享物理端口。S111. Determine whether the registration message is received from a shared physical port, and multiple virtual optical line terminals share the shared physical port.

S112、在所述注册消息接收自所述共享物理端口的情况下，对所述虚拟光线路终端标签的内容进行校验。S112. When the registration message is received from the shared physical port, verify the content of the virtual optical line terminal label.

需要说明的是，在本公开实施例提供的ONU的注册方法的一些实施方式中，对从共享物理端口接收的注册消息进行校验，对从非共享物理端口接收的注册消息则不进行校验，即可确保vOLT只对所属的ONU进行注册，避免不同vOLT之间的信息泄露，提升信息安全性；同时，对从非共享物理端口接收的注册报文则不进行校验，有利于节约vOLT的计算资源，还能提升通过非共享物理端口接入的ONU的注册效率。It should be noted that in some implementations of the ONU registration method provided by the embodiments of the present disclosure, the registration message received from the shared physical port is verified, and the registration message received from the non-shared physical port is not verified. , which can ensure that the vOLT only registers the ONU to which it belongs, avoiding information leakage between different vOLTs and improving information security; at the same time, registration messages received from non-shared physical ports are not verified, which is beneficial to saving vOLT Computing resources can also improve the registration efficiency of ONUs connected through non-shared physical ports.

需要说明的是，在本公开实施例提供的ONU的注册方法的一些实施方式中，对从共享物理端口和非共享物理端口接收的注册报文都进行校验，既可以确保vOLT只对所属的ONU进行注册，避免不同vOLT之间的信息泄露，提升信息安全性，也可以避免由于将ONU通过错误的非共享物理端口接入而注册到错误的vOLT，有利于进一步提升信息安全性。It should be noted that in some implementations of the ONU registration method provided by the embodiments of the present disclosure, the registration messages received from the shared physical port and the non-shared physical port are verified, which can ensure that the vOLT only registers the Registering the ONU avoids information leakage between different vOLTs and improves information security. It also avoids registering the ONU to the wrong vOLT due to connecting the ONU through the wrong non-shared physical port, which is helpful to further improve information security.

本公开实施例对于虚拟光线路终端标签的内容与当前的vOLT的标识不一致时如何处理注册消息不做特殊限定。例如，当光线路终端标签的内容与当前的vOLT的标识不一致时，可以对注册消息做丢弃处理。The embodiment of the present disclosure does not place special restrictions on how to process the registration message when the content of the virtual optical line terminal tag is inconsistent with the identification of the current vOLT. For example, when the content of the optical line terminal tag is inconsistent with the identification of the current vOLT, the registration message can be discarded.

相应地，在一些实施方式中，参照图4，所述ONU的注册方法还包括S13。Correspondingly, in some embodiments, referring to Figure 4, the ONU registration method further includes S13.

S13、在所述虚拟光线路终端标签的内容与当前的所述虚拟光线路终端的标识不一致的情况下，丢弃所述注册消息。 S13. If the content of the virtual optical line terminal label is inconsistent with the current identification of the virtual optical line terminal, discard the registration message.

现行标准定义的ONU的发现注册机制中，OLT通过下行GTC帧的BWMap字段，开一个公共的上行空白窗(quiet window)。所有未注册的ONU都可以在这个空白窗中向OLT发送该ONU的序列号。新上线的ONU将其序列号放在Serial_Number_ONU PLOAM消息中，发送给OLT。OLT收到上行的Serial_Number_ONU PLOAM消息后，在该OLT的未注册ONU列表中加入该新上线的ONU的序列号，然后根据未注册ONU列表下发ONU注册命令，完成ONU注册管理。In the ONU discovery and registration mechanism defined by the current standard, the OLT opens a common upstream quiet window through the BWMap field of the downstream GTC frame. All unregistered ONUs can send the ONU's serial number to the OLT in this blank window. The newly online ONU puts its serial number in the Serial_Number_ONU PLOAM message and sends it to the OLT. After receiving the upstream Serial_Number_ONU PLOAM message, the OLT adds the serial number of the newly online ONU to the OLT's unregistered ONU list, and then issues the ONU registration command according to the unregistered ONU list to complete ONU registration management.

在一些实施方式中，注册消息用于ONU将其序列号发送给vOLT，使得vOLT能够按照现行标准中定义的ONU的发现注册机制对ONU进行注册管理。In some implementations, the registration message is used by the ONU to send its serial number to the vOLT, so that the vOLT can register and manage the ONU according to the ONU discovery and registration mechanism defined in the current standard.

相应地，在一些实施方式中，所述注册消息为Serial_Number_ONU PLOAM消息。Correspondingly, in some implementations, the registration message is a Serial_Number_ONU PLOAM message.

需要说明的是，在本公开实施例中，是在不改变现行标准中定义的Serial_Number_ONU PLOAM消息的格式的基础上，在Serial_Number_ONU PLOAM消息中定义虚拟光线路终端标签，并在虚拟光线路终端标签中标注ONU归属的vOLT的标识。It should be noted that in the embodiment of the present disclosure, on the basis of not changing the format of the Serial_Number_ONU PLOAM message defined in the current standard, the virtual optical line terminal label is defined in the Serial_Number_ONU PLOAM message, and in the virtual optical line terminal label Mark the identity of the vOLT to which the ONU belongs.

本公开实施例对于如何在Serial_Number_ONU PLOAM消息中定义虚拟光线路终端标签不做特殊限定。The embodiment of this disclosure does not make any special limitations on how to define the virtual optical line terminal label in the Serial_Number_ONU PLOAM message.

根据现行标准，Serial_Number_ONU PLOAM消息的第二个字节表示Message ID字段，而Message ID字段的前三个比特(bit)未做明确定义。在一些实施方式中，在Message ID字段的前三个bit中定义虚拟光线路终端标签。According to the current standard, the second byte of the Serial_Number_ONU PLOAM message represents the Message ID field, and the first three bits of the Message ID field are not clearly defined. In some implementations, the virtual optical line terminal label is defined in the first three bits of the Message ID field.

相应地，在一些实施方式中，所述Serial_Number_ONU PLOAM消息包括Message ID字段，所述Message ID字段的前三个比特中的至少一者定义为所述虚拟光线路终端标签。Correspondingly, in some implementations, the Serial_Number_ONU PLOAM message includes a Message ID field, and at least one of the first three bits of the Message ID field is defined as the virtual optical line terminal label.

例如，可以将Message ID字段的第一个bit、第二个bit、第三个bit中的任意一者定义为虚拟光线路终端标签，也可以将Message ID字段的第一个bit、第二个bit、第三个bit中的任意两者定义为虚拟光线路终端标签，还可以将Message ID字段的前三个比特均定义为虚拟光线路终端标签。 For example, any one of the first bit, second bit, and third bit of the Message ID field can be defined as the virtual optical line terminal label, or the first bit, second bit, and second bit of the Message ID field can be defined as the virtual optical line terminal label. Any two of the bit and the third bit are defined as the virtual optical line terminal label, and the first three bits of the Message ID field can also be defined as the virtual optical line terminal label.

需要说明的是，将Message ID字段的前三个比特中的至少一者定义为虚拟光线路终端标签，能够与现行标准兼容，降低OLT和vOLT的升级难度，提升兼容性。It should be noted that defining at least one of the first three bits of the Message ID field as a virtual optical line terminal label can be compatible with current standards, reduce the difficulty of upgrading OLT and vOLT, and improve compatibility.

在一些实施方式中，参照图4，所述ONU的注册方法还包括S14。In some embodiments, referring to Figure 4, the ONU registration method further includes S14.

S14、为所述光线路终端中配置的虚拟光线路终端分配标识。S14. Assign an identifier to the virtual optical line terminal configured in the optical line terminal.

例如，一个OLT虚拟成8个vOLT,按照0至7编号，每一个vOLT分配一个编号作为标识。For example, an OLT is virtualized into 8 vOLTs, numbered from 0 to 7, and each vOLT is assigned a number as an identifier.

本公开实施例对于将光网络单元注册到当前的虚拟光线路终端上的注册流程不做特殊限定。例如，注册消息是Serial_Number_ONU PLOAM消息，标识与虚拟光线路终端标签的内容一致的vOLT按照现行标准执行ONU的注册流程。The embodiment of the present disclosure does not place special limitations on the registration process of registering the optical network unit to the current virtual optical line terminal. For example, the registration message is a Serial_Number_ONU PLOAM message, and the vOLT that identifies the content consistent with the virtual optical line terminal label performs the ONU registration process in accordance with current standards.

在一些实施方式中，所述注册消息为新增PLOAM消息，所述新增PLOAM消息中携带所述虚拟光线路终端标签。In some implementations, the registration message is a new PLOAM message, and the new PLOAM message carries the virtual optical line terminal label.

需要说明的是，在一些实施方式中，定义新增PLOAM消息作为注册消息，该新增PLOAM消息与现行标准定义的ONU发现和注册流程中OLT和ONU之间交互的PLOAM消息均不同。在新增PLOAM消息中携带vOLT标签，用来标注ONU归属的vOLT的标识(vOLT ID)。It should be noted that in some implementations, a new PLOAM message is defined as a registration message, and the new PLOAM message is different from the PLOAM message interacted between the OLT and ONU in the ONU discovery and registration process defined by current standards. The new PLOAM message carries the vOLT label, which is used to mark the identification (vOLT ID) of the vOLT to which the ONU belongs.

在一些实施方式中，所述ONU的注册方法还包括：当任意一个vOLT获取到ONU的序列号时，将ONU的序列号添加到当前的vOLT的未注册ONU列表；以及在所述虚拟光线路终端标签的内容与当前的vOLT的标识不一致的情况下，将ONU的序列号从当前的vOLT的未注册ONU列表中删除。In some embodiments, the ONU registration method further includes: when any vOLT obtains the serial number of the ONU, adding the serial number of the ONU to the unregistered ONU list of the current vOLT; and in the virtual optical line If the content of the terminal label is inconsistent with the identification of the current vOLT, the ONU serial number is deleted from the unregistered ONU list of the current vOLT.

在一些实施方式中，ONU把自己的序列号放在Serial_Number_ONU PLOAM消息中，并将Serial_Number_ONU PLOAM消息发送给配置有至少一个vOLT的OLT。OLT中的各vOLT接收Serial_Number_ONU PLOAM消息获取ONU的序列号。在虚拟光线路终端标签的内容与当前的vOLT的标识一致的情况下，则按照现行标准定义的ONU发现和注册流程对ONU进行注册；在虚拟光线路终端标签的内容与当前的vOLT的标识不一致的情况下，将ONU的序列号从当前的vOLT的未注册ONU列表中删除，使得该ONU对运维人员不可见，从而避免ONU注册到错误的vOLT。In some implementations, the ONU puts its serial number in the Serial_Number_ONU PLOAM message, and sends the Serial_Number_ONU PLOAM message to the OLT configured with at least one vOLT. Each vOLT in the OLT receives the Serial_Number_ONU PLOAM message to obtain the serial number of the ONU. When the content of the virtual optical line terminal label is consistent with the identity of the current vOLT, the ONU is registered according to the ONU discovery and registration process defined by the current standard; when the content of the virtual optical line terminal label is inconsistent with the identity of the current vOLT In this case, delete the ONU's serial number from the current vOLT's unregistered ONU list, making the ONU invisible to operation and maintenance personnel. This prevents the ONU from registering to the wrong vOLT.

为了使本领域技术人员能够更清楚地理解本公开实施例提供的技术方案，下面通过具体的三个实例，对本公开实施例提供的技术方案进行详细说明：In order to enable those skilled in the art to more clearly understand the technical solutions provided by the embodiments of the present disclosure, the technical solutions provided by the embodiments of the present disclosure are described in detail below through three specific examples:

实例一Example 1

在本实例中，一个OLT虚拟成8个vOLT，按照0至7编号，每一个vOLT分配一个编号作为标识。In this example, one OLT is virtualized into 8 vOLTs, numbered from 0 to 7, and each vOLT is assigned a number as an identifier.

按照现行标准，OLT和ONU之间交互的PLOAM消息的格式包含13个字节(byte)，第二个byte表示Message ID字段。在本实例中，将Message ID字段的前三个bit定义为vOLT标签，用来标注ONU归属的vOLT的标识(vOLT ID)。According to current standards, the format of the PLOAM message exchanged between OLT and ONU contains 13 bytes (byte), and the second byte represents the Message ID field. In this example, the first three bits of the Message ID field are defined as vOLT tags, which are used to mark the identification (vOLT ID) of the vOLT to which the ONU belongs.

ONU在发送PLOAM消息时，在PLOAM消息的vOLT标签中标注该ONU归属的vOLT的vOLT ID，使得只有该ONU归属的vOLT才能识别并处理该PLOAM消息，避免该ONU被其他vOLT发现和注册。When an ONU sends a PLOAM message, it marks the vOLT ID of the vOLT to which the ONU belongs in the vOLT tag of the PLOAM message, so that only the vOLT to which the ONU belongs can identify and process the PLOAM message, preventing the ONU from being discovered and registered by other vOLTs.

OLT存在共享PON端口的场景下，OLT中的任意一个vOLT收到来自共享PON端口的PLOAM消息，对Message ID字段的前三个bit表示的vOLT标签的内容进行校验；当vOLT标签的内容与当前的vOLT ID一致时，对注册消息进行处理；当vOLT标签的内容与当前的vOLT ID不一致时，丢弃注册消息。In the scenario where the OLT has a shared PON port, any vOLT in the OLT receives the PLOAM message from the shared PON port and verifies the content of the vOLT tag represented by the first three bits of the Message ID field; when the content of the vOLT tag matches Current vOLT When the IDs are consistent, the registration message is processed; when the content of the vOLT tag is inconsistent with the current vOLT ID, the registration message is discarded.

vOLT收到来自非共享PON端口的PLOAM消息时，可以对Message ID字段的前三个bit进行校验，也可以不进行校验。When vOLT receives a PLOAM message from a non-shared PON port, it can verify the first three bits of the Message ID field or not.

实例二Example 2

在本实例中，基于现行标准，ONU发现和注册流程包括1至18。In this example, based on current standards, the ONU discovery and registration process includes steps 1 to 18.

1、OLT每隔125微秒(us)，发送一个下行GTC帧。1. The OLT sends a downlink GTC frame every 125 microseconds (us).

2、ONU接收到下行GTC帧之后，清除本地LOS/LOF，从O1状态进入O2状态。2. After receiving the downlink GTC frame, the ONU clears the local LOS/LOF and enters the O2 state from the O1 state.

3、OLT发送下行的Upstream_Overhead PLOAM消息，该消息中定义了上行帧的前导码、定界符和ONU均衡时延等参数。3. The OLT sends the downstream Upstream_Overhead PLOAM message, which defines the preamble, delimiter, ONU equalization delay and other parameters of the upstream frame.

4、ONU收到Upstream_Overhead PLOAM消息后，根据消息中的内容，设置上行帧的前导码、定界符和均衡时延等参数，从O2状态进入O3状态。4. After receiving the Upstream_Overhead PLOAM message, the ONU sets the preamble, delimiter, equalization delay and other parameters of the upstream frame according to the content of the message, and enters the O3 state from the O2 state.

5、OLT发送下行的Extended_Burst_Length PLOAM消息，该消息中定义了测距时的上行帧前导码长度和正常工作时的上行帧前导码长度。测距过程中一般使用较长的前导码，有利于OLT捕捉ONU的上行帧信号。5. The OLT sends the downlink Extended_Burst_Length PLOAM message, which defines the uplink frame preamble length during ranging and the uplink frame preamble length during normal operation. A longer preamble is generally used during the ranging process, which is beneficial for the OLT to capture the uplink frame signal of the ONU.

6、ONU收到Extended_Burst_Length PLOAM消息后，根据消息中的内容，设置测距时的上行帧前导码长度和正常工作时的上行帧前导码长度。6. After receiving the Extended_Burst_Length PLOAM message, the ONU sets the uplink frame preamble length during ranging and the uplink frame preamble length during normal operation according to the content in the message.

7、OLT通过下行GTC帧的BWMap字段，开一个公共的上行空白窗(quiet window)。所有未注册的ONU，都可以在这个空白窗中向OLT发送自己的序列号。7. The OLT opens a common upstream quiet window through the BWMap field of the downstream GTC frame. All unregistered ONUs can send their serial numbers to the OLT in this blank window.

8、ONU把自己的序列号放在Serial_Number_ONU PLOAM消息中，Serial_Number_ONU PLOAM消息的Message ID字段定义有vOLT标签,vOLT标签标注了vOLT ID，将Serial_Number_ONU PLOAM消息发送给OLT。8. ONU puts its serial number in the Serial_Number_ONU PLOAM message. The Message ID field of the Serial_Number_ONU PLOAM message is defined with a vOLT tag. The vOLT tag is marked with the vOLT ID, and the Serial_Number_ONU PLOAM message is sent to the OLT.

9、OLT中的任意一个vOLT在收到ONU的序列号后，判断序列号是否是从共享PON端口收到的，若是，则对Message ID字段中定义的vOLT标签进行校验，判断vOLT ID字段是否与当前的vOLT一致；若一致，为ONU分配一个ONU ID，通过Assign_ONU_ID PLOAM消息发送给ONU。9. After any vOLT in the OLT receives the serial number of the ONU, it determines whether the serial number is received from the shared PON port. If so, it defines in the Message ID field Verify the vOLT tag to determine whether the vOLT ID field is consistent with the current vOLT; if consistent, assign an ONU ID to the ONU and send it to the ONU through the Assign_ONU_ID PLOAM message.

10、ONU收到Assign_ONU_ID PLOAM消息，从O3状态进入O4状态。10. ONU receives the Assign_ONU_ID PLOAM message and enters the O4 state from the O3 state.

11、OLT通过下行GTC帧的BWMap字段，为某个ONU ID开一个上行的空白窗(quiet window)。该ONU在这个空白窗中向OLT发送自己的序列号，用于测距。11. The OLT opens an upstream quiet window for a certain ONU ID through the BWMap field of the downstream GTC frame. The ONU sends its own serial number to the OLT in this blank window for ranging.

12、ONU把自己的序列号放在Serial_Number_ONU PLOAM消息中，发送给OLT。12. ONU puts its serial number in the Serial_Number_ONU PLOAM message and sends it to the OLT.

13、OLT在收到ONU的序列号后，计算出ONU的距离和均衡时延参数。通过Ranging_Time PLOAM消息，把均衡时延参数发送给ONU。13. After receiving the ONU's serial number, the OLT calculates the ONU's distance and equalization delay parameters. The equalization delay parameters are sent to the ONU through the Ranging_Time PLOAM message.

14、ONU收到Ranging_Time PLOAM消息，设置自己的均衡时延值，从O4状态进入O5状态。14. ONU receives the Ranging_Time PLOAM message, sets its own equilibrium delay value, and enters the O5 state from the O4 state.

15、如果OLT需要对ONU进行密码验证，会下发Request_password PLOAM消息，要求ONU上报自己的密码。15. If the OLT needs to perform password verification on the ONU, it will send a Request_password PLOAM message, requiring the ONU to report its password.

16、ONU通过Password PLOAM消息，将自己的密码发送给OLT。16. ONU sends its password to the OLT through the Password PLOAM message.

17、ONU密码验证通过，OLT下发Configure Port-ID PLOAM消息，配置ONU的OMCI管理通道。17. The ONU password verification passes, and the OLT issues the Configure Port-ID PLOAM message to configure the ONU's OMCI management channel.

18、ONU设置OMCI管理通道。通过该管理通道，OLT可以配置和管理ONU的业务。18. ONU sets the OMCI management channel. Through this management channel, the OLT can configure and manage the ONU's services.

完成以上操作，ONU注册流程结束。After completing the above operations, the ONU registration process ends.

实例三Example three

在本实例中，一个OLT虚拟成8个vOLT，按照0至7编号，每一个vOLT分配到一个编号作为该vOLT的标识。In this example, one OLT is virtualized into 8 vOLTs, numbered from 0 to 7, and each vOLT is assigned a number as the identification of the vOLT.

定义新增PLOAM消息，该新增PLOAM消息与现行标准定义的ONU发现和注册流程中OLT和ONU之间交互的PLOAM消息均不同。Define a new PLOAM message, which is different from the PLOAM message exchanged between the OLT and ONU in the ONU discovery and registration process defined by the current standard.

在新增PLOAM消息中携带vOLT标签，用来标注ONU归属的vOLT的标识(vOLT ID)。The new PLOAM message carries the vOLT label, which is used to mark the identification (vOLT ID) of the vOLT to which the ONU belongs.

ONU把自己的序列号放在Serial_Number_ONU PLOAM消息中，并将Serial_Number_ONU PLOAM消息发送给OLT。The ONU puts its serial number in the Serial_Number_ONU PLOAM message and Send the Serial_Number_ONU PLOAM message to the OLT.

ONU将携带vOLT标签的新增PLOAM消息也发送给OLT。The ONU also sends the new PLOAM message carrying the vOLT label to the OLT.

vOLT收到Serial_Number_ONU PLOAM消息后，将ONU加入自己的未注册ONU列表中。After vOLT receives the Serial_Number_ONU PLOAM message, it adds the ONU to its own unregistered ONU list.

vOLT收到携带vOLT标签的新增PLOAM消息后，对vOLT标签进行校验，判断vOLT ID字段是否与当前的vOLT一致。若一致，则将ONU注册到当前的vOLT；若不一致，则将该ONU的序列号从当前的vOLT的未注册ONU列表中删除，使得该ONU对运维人员不可见，从而避免ONU注册到错误的vOLT。After the vOLT receives the new PLOAM message carrying the vOLT label, it verifies the vOLT label to determine whether the vOLT ID field is consistent with the current vOLT. If they are consistent, the ONU will be registered to the current vOLT; if they are inconsistent, the serial number of the ONU will be deleted from the unregistered ONU list of the current vOLT, making the ONU invisible to operation and maintenance personnel, thereby avoiding ONU registration errors. vOLT.
