[0051] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0052] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0053] Gigabit-capable passive optical network (GPON) technology is a passive optical network access technology based on ITU-T G series standards. The GPON system includes OLT and optical network unit (ONU). ITU-TG.988 is the internationally accepted standard for ONU management and control interface (OMCI), and the OMCI protocol is a mandatory protocol for OLT management. The OMCI protocol is an underlying management protocol embedded in the GPON / 10G Ethernet-based passive optical network (10G Eethernet Passive Opitcal Network, XGPON) system, and is used for basic configuration related to the passive optical network (PON) interface of the ONU. It is indispensable in the GPON / XGPON system.

[0054] The present invention provides a communication management method, device, system and readable storage medium for optical network equipment. Figure 1 As shown, the optical gateway device connects the OLT and the ONU through an optical distribution network (ODN), the optical gateway device assigns an entity number to the ONU and establishes an optical network unit management control channel with the ONU, the optical gateway device generates a system message including the entity number, and reports the system message to the OLT so that the OLT authenticates the ONU according to the entity number, and receives configuration information sent by the OLT when the ONU authentication passes, the configuration information includes parameters for configuring the ONU to establish communication, and the ONU is configured according to the configuration information so that the ONU communicates with the OLT through the optical gateway device, thereby realizing the management of the ONU by the OLT, and making the management of the ONU by the OLT more flexible.

[0055] It is understandable that in the FTTR scenario, the optical gateway device may be an H-ONU, which serves as a gateway device to connect the OLT and the R-ONU. For the sake of convenience, the H-ONUs involved below may all serve as optical gateway devices.

[0056] The following further describes the embodiments of the present invention in terms of application in FTTR scenarios in conjunction with the accompanying drawings.

[0057] Reference Figure 2 , Figure 2 A communication management method for an optical network device provided by an embodiment of the present invention is applied to an H-ONU, where the H-ONU connects an optical line terminal OLT and an optical network unit ONU. The communication management method includes but is not limited to the following steps:

[0058] Step S100, the H-ONU allocates an entity number corresponding to the ONU, and establishes an optical network unit management control channel OMCC with the ONU.

[0059] After discovering the ONU, the H-ONU assigns a number to the ONU, thereby marking the ONU. For example, the H-ONU discovers three ONUs, namely ONU1, ONU2 and ONU3. The H-ONU assigns entity numbers 0x0001, 0x0002 and 0x0003 to ONU1, ONU2 and ONU3 in turn. The H-ONU establishes OMCCs with ONU1, ONU2 and ONU3 respectively, so that the H-ONU and ONU1, ONU2 and ONU3 transmit instructions through the OMCC.

[0060] It should be noted that the present invention modifies the original OMCI G.988 standard, adds a new R-ONU entity, and the R-ONU is a self-created entity, which supports up to 128 instances, and each R-ONU instance corresponds to the Slot ID in clause 9.1.5 of the OMCI G.988 standard. Wherein, R-ONU attributes (Attributes) include managed entity ID (MEID), link state (Link state), logical identification number (Logical ONU ID, LOID), logical identification password (Logical password, LOPW) and credential status (Credentials status), R-ONU operations (Actions) include getting (get), setting (set) and restarting (reboot), and R-ONU attribute value changes (Attribute value change) include 5 attribute values ​​with sequence numbers 1 to 5, wherein the attribute value with sequence number 1 set to Link state.

[0061] It should be noted that the present invention modifies the original OMCI G.988 standard and further includes adding a new type R-ONU to the TP attribute (TP type) of the MAC bridge port configuration data entity.

[0062] It can be understood that the ONU mentioned in the embodiment of the present invention is the entity R-ONU newly added in the revised OMCI G.988 standard.

[0063] Step S300: The H-ONU generates a system message including an entity number, and reports the system message to the OLT so that the OLT can authenticate the ONU according to the entity number.

[0064] Specifically, the H-ONU reports a system message including an entity number to the OLT, so that the OLT receives information that an ONU has accessed the communication system. The OLT distinguishes multiple ONUs according to the entity numbers of the ONUs. For example, the system message of the H-ONU received by the OLT includes three ONUs, and the entity numbers are 0x0001, 0x0002, and 0x0003, respectively. The ONU authentication and authentication information received by the OLT corresponds to the entity numbers of the ONUs, respectively. For example, the authentication and authentication information corresponding to the ONU with the entity number of 0x0001 is the first information, and the authentication and authentication information corresponding to the ONU with the entity number of 0x0002 is the second information. The OLT performs authentication and authentication on the first information and the second information, respectively. If the first information is authentication passed and the second information is authentication failed, then the ONU with the entity number of 0x0001 passes authentication and authentication, and the ONU with the entity number of 0x0002 fails authentication and authentication.

[0065] Step S500: When the ONU authentication is passed, the H-ONU receives configuration information sent by the OLT, where the configuration information includes parameters for configuring the ONU to establish communication.

[0066] It is understandable that the OLT performs authentication on the ONU. If the authentication is successful, the OLT sends configuration information to the H-ONU, and the configuration information includes information related to the ONU. For example, if the OLT passes the authentication of ONU1, the OLT sends the configuration information of configuring ONU1 to the H-ONU. In addition, the OLT can also send the configuration message of configuring the optical switch device.

[0067] Step S600: The H-ONU configures the ONU according to the configuration information so that the ONU communicates with the OLT through the OMCC.

[0068] Specifically, the H-ONU sends the information related to the ONU to the corresponding ONU, and leaves the rest of the information to the H-ONU for processing. For example, the configuration information includes the first configuration information, the second configuration information, and the third configuration information, wherein the first configuration information is related to ONU1, the second configuration information is related to ONU2, and the third configuration information is not related to ONU, then the H-ONU sends the first configuration information to ONU1, the second configuration information to ONU2, and the third configuration information is left for the H-ONU to process itself. The optical gateway distributes the configuration messages of multiple ONUs to the corresponding ONUs, thereby realizing the flexible and effective management of the OLT to the ONU.

[0069] Reference Figure 3 The allocation of the entity number corresponding to the ONU in step S100 includes: step S110 and step S120.

[0070] Step S110: The H-ONU assigns a management number to the ONU.

[0071] The management number is set according to the number of ONUs.

[0072] Step S120: The H-ONU sets the entity number of the ONU according to the management number.

[0073] Specifically, after discovering the ONU, the H-ONU assigns a management number to the ONU. For example, the H-ONU discovers three ONUs, namely ONU1, ONU2 and ONU3, and the H-ONU sequentially assigns management numbers 1, 2 and 3 to ONU1, ONU2 and ONU3. According to the management number of the ONU, the entity numbers of ONU1, ONU2 and ONU3 are set to 0x0001, 0x0002 and 0x0003 respectively.

[0074] It should be noted that the numerical values ​​assigned to the management numbers in the present invention are not limited. In another embodiment, the management numbers assigned by H-ONU to ONU1, ONU2 and ONU3 are 3, 5 and 7 respectively, and the entity numbers of ONU1, ONU2 and ONU3 are set to 0x0003, 0x0005 and 0x0007.

[0075] It should be noted that the relationship between the management number and the ONU entity number in the present invention is not limited. In another embodiment, the management numbers assigned by H-ONU to ONU1, ONU2 and ONU3 are 3, 5, and 7 respectively, and the entity numbers of ONU1, ONU2 and ONU3 are set to 0x0004, 0x0006 and 0x0008.

[0076] Reference Figure 4 , after step S100, it also includes step S200.

[0077] Step S200: The H-ONU sets the attribute value of the Link state field of the ONU to a first preset value.

[0078] The first preset value is used to indicate that the ONU and the H-ONU are in a connected state.

[0079] It can be understood that the H-ONU sets the attribute value of the Link state field of the ONU to the first preset value, thereby marking the ONU Link state, and the subsequently running program can control the ONU according to the Link state of the ONU.

[0080] Reference Figure 5 The system message also includes a Link state field. The authentication process includes steps S410, S420, and S430:

[0081] Step S410: The H-ONU receives an authentication request generated by the OLT according to the authentication rule.

[0082] The authentication request is used to obtain the authentication code of the ONU, and the authentication request is sent to the H-ONU after the OLT determines that the Linkstate field in the system message is a first preset value.

[0083] Step S420: The H-ONU obtains the authentication code sent by the ONU according to the authentication rule according to the authentication request.

[0084] Step S430: The H-ONU reports the ONU authentication code to the OLT and receives the authentication result issued by the OLT.

[0085] It should be noted that the authentication rules are pre-set in the OLT, and the preset rules are to input a logical identification number and a logical identification password, and the OLT sends the logical identification number and the logical identification password of the ONU whose Link state field is a first preset value to the H-ONU, and the H-ONU sends the message sent to each ONU to each ONU respectively. After the ONU receives the authentication request sent by the optical gateway, it sends its own logical identification number and logical identification password to the H-ONU. After receiving the logical identification number and logical identification password sent by the ONU, the H-ONU matches the logical identification number and the logical identification password with the ONU and sends it to the OLT. For example, the first preset value is 1, the Link state of ONU1 and ONU2 is 1, the OLT sends an authentication request to the H-ONU to obtain the logical identification number and logical identification password of ONU1 and ONU2 respectively, the H-ONU sends an authentication request to ONU1 and ONU2 to obtain the logical identification number and logical identification password respectively, after ONU1 receives the authentication request sent by H-ONU, it sends its own logical identification number 110 and logical identification password 011 to H-ONU, after ONU2 receives the authentication request sent by H-ONU, it sends its own logical identification number 100 and logical identification password 001 to H-ONU, the H-ONU binds the logical identification number 110 and logical identification password 011 of ONU1 to ONU1, binds the logical identification number 100 and logical identification password 001 of ONU2 to ONU2 and sends them to the OLT, and then receives the authentication results of ONU1 and ONU2 issued by the OLT.

[0086] It can be understood that the authentication results of ONU1 and ONU2 sent by the OLT include the setting of the Credentialsstatus attribute value of the ONU. When the authentication passes, the CS attribute value of the ONU is set to 1, and when the authentication fails, the CS attribute value of the ONU is set to 2.

[0087] It is understandable that, in another embodiment, the authentication rules include inputting a logical identification number, inputting a logical identification password, inputting a product serial code, inputting a product serial code and a product serial password, inputting a product serial password, and the like.

[0088] Reference Figure 6 The authentication process also includes step S440, step S450 and step S460.

[0089] Step S440: When the authentication result of the H-ONU is authentication passed, the H-ONU receives a synchronization request sent by the OLT.

[0090] The synchronization request is used to establish synchronization between the OLT and the authenticated ONU.

[0091] Step S450: The H-ONU notifies the authenticated ONU to report a synchronization message according to the synchronization request.

[0092] Step S460: The H-ONU reports the synchronization message to the OLT.

[0093] Specifically, after the ONU passes the authentication, the OLT sends a synchronization request to the H-ONU to obtain the ONU synchronization message. The H-ONU sends the synchronization request to the authenticated ONU and reports the synchronization message returned by the ONU to the OLT.

[0094] It can be understood that the synchronization request includes obtaining the MIB message of the ONU.

[0095] Reference Figure 7 , step S600 includes step S610, step S620 and step S630.

[0096] Step S610: The H-ONU determines a first configuration parameter related to the ONU in the configuration information, and sends the first configuration parameter to the ONU through the OMCC, so that the ONU is configured according to the first configuration parameter.

[0097] Step S620: The H-ONU receives the configuration result message returned by the ONU.

[0098] Step S630: The H-ONU sends a configuration result message to the OLT.

[0099] Specifically, the H-ONU connects to several ONUs at the same time and sends the first configuration parameters corresponding to the ONU to the ONU. For example, the optical gateway connects ONU1 and ONU2, and sends the configuration parameters corresponding to ONU1 to ONU1 through OMCC, and sends the configuration parameters corresponding to ONU2 to ONU2 through OMCC.

[0100] Step S610 includes the H-ONU sending a first configuration parameter to the ONU via a timeslot number corresponding to the ONU.

[0101] It can be understood that the H-ONU allocates a sending time slot to the connected ONU, the time slot number of the time slot corresponding to the ONU is bound to the entity number of the ONU, and the H-ONU sends the first configuration parameter corresponding to the ONU to the ONU through the time slot according to the correspondence between the time slot number and the entity number of the ONU.

[0102] Reference Figure 8 , also includes step S710, step S720, step S730, step S740 and step S750.

[0103] Step S710: When the ONU authentication fails, the H-ONU sets the attribute value of the Link state field of the ONU to a second preset value.

[0104] The second preset value is used to indicate that the ONU and the H-ONU are in a disconnected state;

[0105] Step S720: H-ONU deactivates the ONU;

[0106] Step S730: The H-ONU starts a timer and reactivates the ONU after the timer expires;

[0107] Step S740: The H-ONU sets the attribute value of the Link state field of the ONU to a first preset value, where the first preset value is used to indicate that the ONU and the H-ONU are in a connected state;

[0108] Step S750: The H-ONU sends an attribute value change alarm to the OLT so that the OLT can re-authenticate the ONU.

[0109] Specifically, after the ONU authentication fails, the H-ONU sets the attribute value of the Link state field of the ONU to the second preset value, the H-ONU clears the identification of the ONU and sets the CS attribute value of the ONU to 2, reconnects with the ONU after the timer reaches the timing time, assigns an entity number to the ONU, and sets the attribute value of the ONU to the first preset value. In addition, an attribute value change alarm is sent to the OLT to prompt the OLT to re-authenticate the ONU.

[0110] It can be understood that deactivating the ONU includes the H-ONU clearing the management number and entity number allocated to the ONU.

[0111] It can be understood that the H-ONU connects the OLT and the ONU, the H-ONU assigns an entity number to the ONU and establishes an optical network unit management and control channel with the ONU, the H-ONU generates a system message including the entity number, and reports the system message to the OLT so that the OLT can authenticate the ONU according to the entity number, and when the ONU authentication is passed, receives the configuration information sent by the OLT, the configuration information includes parameters for configuring the ONU to establish communication, and configures the ONU according to the configuration information so that the ONU communicates with the OLT through the H-ONU, thereby realizing the management of the ONU by the OLT and making the management of the ONU by the OLT more flexible.

[0112] Reference Fig. 9Another embodiment of the present invention provides a communication management method for an optical network device, which is applied to an optical line terminal OLT, the OLT is connected to an H-ONU, and the H-ONU is connected to an optical network unit ONU through an optical network unit management control channel OMCC. The communication management method includes but is not limited to the following steps:

[0113] Step S1100: OLT receives a system message sent by H-ONU.

[0114] The system message includes the entity number corresponding to the ONU.

[0115] Step S1200: The OLT authenticates the ONU according to the entity number.

[0116] Step S1300: When the ONU authentication is passed, the OLT sends configuration information to the H-ONU.

[0117] The OLT sends configuration information to the H-ONU, so that the H-ONU configures the ONU according to the configuration information and enables the ONU to communicate with the OLT through the H-ONU. The configuration information includes parameters for configuring the ONU to establish communication.

[0118] Specifically, the OLT receives a system message sent by the optical gateway and reads that a new ONU device has been connected, sets the ONU according to the entity number of the ONU, authenticates the ONU, and sends configuration information to the authenticated ONU according to the entity number.

[0119] Reference Fig.10 The system message also includes a Link state field, and the authentication process includes steps S1210, S1220 and S1230.

[0120] Step S1210: The OLT sends an authentication request generated by the authentication rule to the H-ONU.

[0121] The authentication request is used to obtain the authentication code of the ONU, and the authentication request is sent to the H-ONU after the OLT determines that the Linkstate field in the system message is a first preset value.

[0122] Step S1220: The OLT receives the authentication code of the ONU device reported by the H-ONU.

[0123] Step S1230: The OLT authenticates the authentication code according to the authentication rule, and sends the authentication result to the H-ONU.

[0124] It can be understood that the authentication rules are preset in the OLT, and the preset rules are to input the logical identification number and the logical identification password, the OLT sends the logical identification number and the logical identification password of the ONU whose Link state field is the first preset value to the H-ONU, the H-ONU sends the message sent to each ONU to each ONU respectively, and after the ONU receives the authentication request sent by the optical gateway, it sends its own logical identification number and logical identification password to the H-ONU, and after receiving the logical identification number and logical identification password sent by the ONU, the H-ONU matches the logical identification number and the logical identification password with the ONU and sends it to the OLT. For example, the first preset value is 1, the Link state of ONU1 and ONU2 is 1, the OLT sends an authentication request to the H-ONU to obtain the logical identification number and logical identification password of ONU1 and ONU2 respectively, the H-ONU sends an authentication request to ONU1 and ONU2 to obtain the logical identification number and logical identification password respectively, after ONU1 receives the authentication request sent by H-ONU, it sends its own logical identification number 110 and logical identification password 011 to H-ONU, after ONU2 receives the authentication request sent by H-ONU, it sends its own logical identification number 100 and logical identification password 001 to H-ONU, the H-ONU binds the logical identification number 110 and logical identification password 011 of ONU1 to ONU1, binds the logical identification number 100 and logical identification password 001 of ONU2 to ONU2 and sends them to the OLT, and then receives the authentication results of ONU1 and ONU2 issued by the OLT.

[0125] It can be understood that the authentication results of ONU1 and ONU2 sent by the OLT include the setting of the Credentialsstatus attribute value of the ONU. When the authentication passes, the CS attribute value of the ONU is set to 1, and when the authentication fails, the CS attribute value of the ONU is set to 2.

[0126] Reference Fig.11 The authentication process includes step S1240 and step S1250.

[0127] Step S1240: When the authentication result is authentication passed, the OLT sends a synchronization request to the H-ONU.

[0128] Step S1250: The OLT receives the synchronization message reported by the H-ONU.

[0129] Specifically, the same H-ONU is connected to several ONUs, the OLT sends the synchronization request of the ONU synchronization message to the H-ONU corresponding to the ONU, the H-ONU sends the synchronization request of the synchronization message to the corresponding ONU and sends the synchronization message returned by the ONU to the OLT.

[0130] It can be understood that the synchronization request includes obtaining the MIB message of the ONU.

[0131] It can be understood that the OLT sends an acquisition request for obtaining the ONU system message to the H-ONU, and receives the ONU system message sent by the H-ONU, thereby enabling the OLT to read the ONU system message, thereby facilitating the OLT to configure the ONU and making the OLT's management of the ONU more flexible.

[0132] In order to explain the communication management method of the optical network device provided by the present invention in more detail, the technical solution of the present invention is described with three specific examples as follows.

[0133] Example 1: The application scenario is the OLT acquisition phase of the ONU, where R-ONU represents the ONU mentioned in the embodiment of the present application. The H-ONU is connected to 4 R-ONUs, all R-ONU optical fibers are connected, except for R-ONU4 which is not powered on, all other R-ONUs are powered on, R-ONU1, R-ONU2, and R-ONU4 have been registered on the OLT in LOID mode, R-ONU3 has not been registered, and the H-ONU has been registered on the OLT in SN mode.

[0134] The communication management method of the optical network device in this example is as follows:

[0135] 1. H-ONU automatically discovers three R-ONUs, assigns numbers 1, 2, and 3 to R-ONU1, R-ONU2, and R-ONU3, and the corresponding R-ONU entity MEIDs are 0x0001, 0x0002, and 0x0003, respectively. It establishes OMCC channels with R-ONU1, R-ONU2, and R-ONU3, respectively, and sets the Link state of R-ONU1, R-ONU2, and R-ONU3 instances to 1.

[0136] 2. H-ONU is connected to the optical fiber connected to OLT, and H-ONU generates a MIB message containing R-ONU1, R-ONU2 and R-ONU3 entities and reports it to OLT.

[0137] 3. OLT receives R-ONU instances 0x0001, 0x0002, and 0x0003 reported by H-ONU, and sends get messages to R-ONU1, R-ONU2, and R-ONU3 respectively to obtain LOID and LOPW.

[0138] 4. H-ONU obtains the LOID and LOPW messages of R-ONU and sends them to R-ONU1, R-ONU2 and R-ONU3.

[0139] 5. The R-ONUs that receive the message return LOID and LOPW to the H-ONU respectively.

[0140] 6. H-ONU sends the message returned by R-ONU to OLT.

[0141] 7. OLT authenticates each R-ONU in combination with the authentication method, and finds that R-ONU1 and R-ONU2 have been registered with LOID and the LOID matches. It sends a set message to R-ONU1 and R-ONU2, with the Credentials status attribute set to 1, and sends a set message to R-ONU3, with the Credentials status attribute set to 2. At the same time, it initiates a MIB synchronization request for R-ONU1 and R-ONU2 that have been successfully authenticated.

[0142] 8. H-ONU sends a message to obtain MIB synchronization to the authenticated R-ONU1 and R-ONU2. Set the Linkstate attribute of the R-ONU3 instance that has not passed the authentication to 0, and H-ONUDeactivateR-ONU3. After receiving the message, R-ONU3 jumps to the O2 state. At the same time, H-ONU starts the timer TReg (the default value of TReg is 60s). Before the timer times out, H-ONU does not allocate R-ONU-ID to R-ONU3, so R-ONU will not enter the O4 state. After the timer times out, R-ONU3 is rediscovered by H-ONU, and the Linkstate attribute of the R-ONU3 instance is set to 1, and an attribute value change alarm is sent to the OLT (the Linkstate attribute value in the R-ONU entity is changed). After receiving the attribute value change alarm, OLT will re-initiate LOID and LOPW query messages to R-ONU3. If R-ONU3 is registered on OLT during this period, the authentication will be successful. If not, the authentication process will be repeated.

[0143] 9. R-ONU1 and R-ONU2 that have successfully authenticated report MIB synchronization messages to H-ONU.

[0144] 10. H-ONU reports the MIB synchronization message reported by R-ONU1 and R-ONU2 to OLT.

[0145] When the R-ONU4 power is turned on, the communication management method of R-ONU4 is as follows:

[0146] 1. H-ONU automatically discovers R-ONU4, assigns the room edge ONU (R-ONU) number 4, and the corresponding R-ONU entity MEID is 0x0004. R-ONU4 establishes an OMCC channel and sets the Link state of the R-ONU4 instance to 1.

[0147] 2. H-ONU sends an AVC alarm to OLT (Link state attribute value in R-ONU4 changes).

[0148] 3. OLT sends a get message to R-ONU4 to obtain the LOID and LOPW of R-ONU4.

[0149] 4. H-ONU obtains the LOID and LOPW message of R-ONU and sends it to R-ONU4.

[0150] 5. R-ONU4 returns LOID and LOPW to H-ONU.

[0151] 6. H-ONU sends the message returned by R-ONU4 to OLT.

[0152] 7. OLT authenticates R-ONU4 in combination with the authentication method, and finds that R-ONU4 has been registered with LOID and the LOID matches. It sends a set message to R-ONU4, sets the Credentials status attribute to 1, and initiates a MIB synchronization request to R-ONU4.

[0153] 8. H-ONU sends a message for obtaining MIB synchronization to R-ONU4.

[0154] 9. R-ONU4 reports MIB synchronization message to H-ONU.

[0155] 10. H-ONU reports the MIB synchronization message of R-ONU4 to OLT.

[0156] Example 2: Reference Figures 12 to 16 The application scenario of Example 2 is the OLT configuration phase for ONU. R-ONU is connected to H-ONU through the LAN port of H-ONU. H-ONU is connected to 4 R-ONUs. Each R-ONU has 4 eth ports, 2 pots ports, 1 veip port, 4 wifi ports, 10 iphost4, 10 iphost6, 8 tcont (including tcont0), 8 upstream pqs on each tcont, and 8 downstream pqs on each eth port. The slot IDs assigned to R-ONU1, R-ONU2, R-ONU3, and R-ONU4 are 32, 33, 34, and 35 respectively. The configuration rule on H-ONU is to configure vlan (100, 1) on eth1 port to convert to vlan (1001, 1), and the upstream goes out from Tcont (MEID: 0x8001). The entity model on H-ONU is as follows: Fig.12; The configuration rule on R-ONU1 is to convert vlan (200, 2) to vlan (1002, 2) on the eth1 port, and the uplink goes out from Tcont (MEID: 0x2001). The physical model on R-ONU1 is as follows Fig.13 ; The configuration rule on R-ONU2 is to configure vlan (300, 3) on the eth1 port to convert to vlan (1003, 3), and the uplink goes out from Tcont (MEID: 0x2101). The physical model on R-ONU2 is as follows Fig.15 .

[0157] The communication management method of the optical network device in this example is as follows:

[0158] 1. OLT sends a series of messages to H-ONU. It should be noted that when configuring the channel of R-ONU, the corresponding channel configuration of H-ONU is required at the same time.

[0159] 2. After receiving the message sent by OLT, H-ONU keeps its own message for processing according to Slot ID and mutual pointing relationship, and sends the relevant messages of R-ONU1 and R-ONU2 to the corresponding R-ONU.

[0160] 3. H-ONU queries other entities on the path according to the entity pointing relationship, and finally forms the following Fig.12 , Fig.14 , Fig.16 The channel example configures the information correctly and replies to the OLT.

[0161] 4. R-ONU1 receives the message sent by H-ONU, queries other entities on the path according to the entity pointing relationship, and finally forms the following Fig.13 channel example, configure the information correctly, and reply the message to H-ONU.

[0162] 5. R-ONU2 receives the message sent by H-ONU, queries other entities on the path according to the entity pointing relationship, and finally forms the following Fig.15 channel example, configure the information correctly, and reply the message to H-ONU.

[0163] 6. After receiving the reply message from R-ONU1 and R-ONU2, H-ONU directly forwards it to OLT.

[0164] Example 3: Reference Fig.17 and Fig.18, the application scenario of Example 3 is the OLT configuration phase for ONU, the scenario where R-ONU accesses the Internet via WIFI. There are 4 R-ONUs under H-ONU, each R-ONU has 4 eth ports, 2 pots ports, 1 veip port, 4 wifi ports, 10 iphost4, 10 iphost6, 8 tcont (including tcont0), 8 upstream pqs on each tcont, and 8 downstream pqs on each eth port. The slot IDs assigned to R-ONU1, R-ONU2, R-ONU3, and R-ONU4 are 32, 33, 34, and 35 respectively. The configuration rule on R-ONU1 is to configure untag and tag on the wifi1 port, the vlan is (2001,1), and the upstream goes out from Tcont (MEID: 0x2001). The physical model on R-ONU1 is as follows: Fig.17 .

[0165] The communication management method of the optical network device in this example is as follows:

[0166] 1. OLT sends a series of messages to H-ONU. It should be noted that when configuring the channel for R-ONU, it is necessary to configure the corresponding channel for H-ONU at the same time. If there is no corresponding channel configuration on H-ONU, the link between OLT and R-ONU will be blocked, resulting in the inability of data flow.

[0167] 2. After receiving the message sent by OLT, H-ONU keeps its own message for processing according to Slot ID and mutual pointing relationship, and sends the message related to R-ONU1 to R-ONU1.

[0168] 3. H-ONU queries other entities on the path according to the entity pointing relationship, and finally forms the following Fig.18 The channel example configures the information correctly and replies to the OLT.

[0169] 4. R-ONU1 receives the message sent by H-ONU, queries other entities on the path according to the entity pointing relationship, and finally forms the following Fig.17 The channel example configures the information correctly and replies to the H-ONU.

[0170] 5. After receiving the reply message from R-ONU1, H-ONU directly forwards it to OLT.
