To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0043] To address the problems of the prior art, embodiments of this application provide a networking system, networking method, apparatus, device, and computer storage medium. The following first illustrates an example of the networking method applicable to embodiments of this application.

[0044] Figure 1 A schematic diagram of the network system provided in one embodiment of this application is shown. Figure 1 As shown, the system includes: a network management server, and an optical gateway and an optical router respectively connected to the network management server; the optical gateway includes a first uplink optical interface and multiple downlink optical interfaces, one end of the first uplink optical interface is connected to the metropolitan area network for communication, and the other end is connected to the multiple downlink optical interfaces; the optical router includes multiple second uplink optical interfaces and multiple Ethernet ports, the second uplink optical interfaces are correspondingly connected to the downlink optical interfaces, and the multiple second uplink optical interfaces are connected to the multiple Ethernet ports.

[0045] In this embodiment, the optical gateway can be an FTTR optical gateway, and the optical router can be an FTTR optical router; wherein, the optical gateway, the optical router and the network management server are respectively connected for communication.

[0046] Figure 2 A schematic diagram of the structure of an optical gateway provided in one embodiment of this application is shown, as follows: Figure 2As shown, the optical gateway is deployed on the user side. The optical gateway also includes a control unit connected to a first uplink optical interface and multiple downlink optical interfaces, as well as a switching processing unit and several RJ45 Ethernet interfaces connected sequentially to the control unit. The control unit is used to implement signal logic transmission between the first uplink optical interface and the multiple downlink optical interfaces. The switching processing unit is used to convert optical signals into electrical signals and send them to the RJ45 Ethernet interfaces. The RJ45 Ethernet interfaces are used to connect to external network devices and support dual-band WiFi 6 functionality. The first uplink optical interface is a 10G PON optical interface, and the downlink optical interfaces are G / EPON OLT optical interfaces. It should be noted that the 10GPON optical interface supports three standards: Standard 1 independently supports 10G EPON mode; Standard 2 independently supports 10GGPON (including 10GS PON) mode; and Standard 3 is an adaptive mode for 10G EPON and 10G GPON (10GS PON).

[0047] Figure 3 A schematic diagram of the structure of an optical router provided in one embodiment of this application is shown, as follows: Figure 3 As shown, optical routers are typically deployed in the outermost room on the user side. An optical router includes a PON MAC module, a CPLD control unit, a switching processing unit, and RJ45 Ethernet interfaces. The PON MAC module is connected to each of the second uplink optical interfaces. The CPLD control unit is connected to the PON MAC module, and the switching processing unit is connected to the CPLD control unit. The CPLD control unit is also connected to multiple RJ45 Ethernet interfaces. The PON MAC module and CPLD control unit are used to implement signal transmission between the second uplink optical module and the switching control unit, while ensuring the independence of the multiple uplink G / EPON optical interfaces and ensuring hardware isolation between them. The switching control unit converts optical signals into electrical signals and sends them to the RJ45 Ethernet interfaces. The RJ45 Ethernet interfaces are used to connect external network devices and support dual-band WiFi 6 functionality. It should be noted that the second uplink optical interface is a G / EPON optical interface, which supports three standards: Standard 1 independently supports EPON mode, Standard 2 independently supports GPON mode, and Standard 3 is an adaptive mode for EPON and GPON.

[0048] The network management server is used to receive downlink signals sent by the metropolitan area network through the first uplink optical interface, obtain the first communication interruption information of multiple downlink optical interfaces, and determine the first target interface among the multiple downlink optical interfaces based on the first communication interruption information, and send downlink signals to the first target interface.

[0049] Between the optical gateway and the optical router, multiple signal transmission links can be formed through a first uplink optical interface, multiple downlink optical interfaces, and multiple second uplink optical interfaces. When transmitting downlink signals from the first uplink optical interface to the downlink optical interface in the optical gateway, the first communication interruption status of the first main interface in the downlink optical interface can be determined first. Based on the first interruption status, a target interface can be selected from the multiple second uplink optical interfaces for downlink signal transmission, thereby ensuring that downlink signals can still be transmitted in the optical gateway even when the transmission link is interrupted.

[0050] The optical router is used to obtain the second communication interruption information of multiple second uplink optical interfaces, determine the second target interface among the multiple second uplink optical interfaces based on the second communication interruption information, transmit downlink signals through the second target interface, and send the downlink signals to multiple Ethernet ports through the second target interface.

[0051] When the downlink signal is transmitted from the optical gateway to the optical router, there are multiple one-to-one connected downlink optical interfaces and second uplink optical interfaces between the optical gateway and the optical router. Therefore, there are also multiple transmission links between the optical gateway and the optical router. In order to ensure normal signal transmission between the optical gateway and the optical router, the second communication interruption information of the second uplink optical interface can be obtained, and the second communication interruption information can be selected as the normal transmission link for signal transmission.

[0052] In this embodiment, the above-described device enables the formation of multiple links for transmitting downlink signals between the optical gateway and the optical router via the first uplink optical interface, the downlink optical interface, and the second downlink optical interface. It can also select the normally communicating link for transmitting downlink signals based on the communication interruption information of each interface, effectively reducing the probability of service interruption accidents caused by link blockage, reducing link maintenance costs, and improving the speed of fault detection and repair.

[0053] In one embodiment of this application, the networking system further includes an OLT device. The OLT device includes an OLT MAC interface and an OLT optical interface. The OLT MAC interface is connected to the metropolitan area network, and the OLT optical interface is connected to a first uplink optical interface. The OLT device receives downlink signals sent by the metropolitan area network through the OLT MAC interface and sends the downlink signals to the optical gateway through the OLT optical interface.

[0054] In this embodiment, refer to Figure 2 The OLT (Optical Line Terminal) device, located in the operator's central office equipment room, is a terminal device used to connect to the metropolitan area network (MAN) and exchange data with the MAN. It mainly includes the OLT uplink port, OLT MAC interface, and OLT optical interface. Downlink signals between the OLT and the FTTR optical router are transmitted via broadcast, while uplink signals are transmitted using TDMA (Time Division Multiple Access).

[0055] In one embodiment of this application, the networking system further includes a first optical splitter and a plurality of second optical splitters, one end of the first optical splitter being connected to the OLT optical interface and the other end being connected to the first uplink optical interface;

[0056] One end of each of the multiple second optical splitters is connected to each of the multiple downlink optical interfaces, and the other end is connected to each of the multiple second uplink optical interfaces.

[0057] In this embodiment, the beam splitter is a passive optical device, also known as an optical splitter, which consists of entrance and exit slits, a reflector, and a dispersive element. In this embodiment, the function of the first beam splitter is to extend the connection of the optical gateway device. Figure 2 As shown, multiple optical gateway devices, such as FTTR optical gateway #1, FTTR optical gateway #2 and FTTR optical gateway #3, can be connected via a splitter.

[0058] The function of the second optical splitter is to extend the connection of optical router devices, such as... Figure 2 As shown, the second optical splitter also includes a first sub-splitter and a second sub-splitter. Multiple optical router devices, such as FTTR optical router #1, FTTR optical router #2, and FTTR optical router #3, can be connected through the first sub-splitter.

[0059] In this embodiment, the first and second optical splitters can support the connection of multiple optical gateways and optical routers, thereby providing multiple signal transmission links and ensuring the stability of signal transmission.

[0060] In one embodiment of this application, the plurality of downlink optical interfaces include a first main interface and a first backup interface, and the plurality of second uplink optical interfaces include a second main interface and a second backup interface. The first main interface and the second main interface are connected through a first optical splitter, and the first backup interface and the second backup interface are connected through a second optical splitter.

[0061] The second optical splitter includes a first sub-optical splitter. One end of the first sub-optical splitter is connected to the first main interface, and the other end is connected to the second main interface. The first main interface, the first sub-optical splitter, and the second main interface constitute the primary all-optical link.

[0062] The second optical splitter also includes a second sub-optical splitter. One end of the second sub-optical splitter is connected to the first backup interface, and the other end is connected to the second backup interface. The first backup interface, the second sub-optical splitter, and the second backup interface constitute a backup all-optical link.

[0063] In this embodiment, during downlink signal transmission, transmission is preferentially performed via the primary all-optical link. If the primary all-optical link experiences a communication interruption, transmission is then performed via the backup all-optical link. Figure 2 As shown, the transmission link consisting of the first main interface, the first sub-splitter, and the second main interface can be represented by nodes B, C, and D. The backup all-optical link consisting of the first backup interface, the second sub-splitter, and the second backup interface can be represented by nodes E, F, and G.

[0064] It should be noted that there can be multiple first backup interfaces, and correspondingly, there can also be multiple second sub-splitters and second backup interfaces. This can form multiple backup all-optical links, thereby reducing the probability of communication interruption due to failure of multiple transmission links.

[0065] To address the problems of the prior art, embodiments of this application provide a networking method. The following first illustrates examples of the networking method applicable to embodiments of this application.

[0066] Figure 4 A flowchart illustrating a networking method provided in one embodiment of this application is shown. Figure 4 As shown, the method includes:

[0067] Step 401: Receive downlink signals sent by the metropolitan area network through the first uplink optical interface;

[0068] Step 402: Obtain the first communication interruption information of multiple downlink optical interfaces through the network management server;

[0069] Step 403: Based on the first communication interruption information, the network management server determines the first target interface among the plurality of downlink optical interfaces;

[0070] Step 404: Send the downlink signal to the first target interface through the first uplink optical interface;

[0071] Step 405: Obtain the second communication interruption information of multiple second uplink optical interfaces through the optical router;

[0072] Step 406: Based on the second communication interruption information, determine the second target interface from the plurality of second uplink optical interfaces through the optical router;

[0073] Step 407: Receive the downlink signal sent by the first target interface through the second target interface;

[0074] Step 408: Send the downlink signal to multiple Ethernet ports through the second target interface.

[0075] In step 401, the downlink signal is transmitted to the OLT device through the metropolitan area network, and then transmitted to the optical gateway through the OLT device. The first uplink optical interface in the optical network management system receives the downlink signal.

[0076] In step 402, the first communication interruption information of multiple downlink optical interfaces is obtained through the network management server;

[0077] The aforementioned first communication interruption information may include communication interruption information for the first main interface and the first backup interface;

[0078] In step 403, based on the first communication interruption information, the network management server determines the first target interface among the plurality of downlink optical interfaces;

[0079] Since downlink signals are preferentially transmitted through the primary all-optical link, step 403 requires prioritizing the determination of whether there is a communication interruption at the first primary interface. Therefore, in one embodiment, step 403 further includes:

[0080] If the first communication interruption information indicates that there is a communication interruption at the first main interface, then the first backup interface is determined to be the first target interface.

[0081] In this embodiment, if communication is interrupted at the first primary interface, downlink signal transmission needs to be carried out through the first backup interface; therefore, the first backup interface must be used as the first target interface. For example, such as... Figure 2 As shown, the first primary interface is G / EPON OLT optical interface #1, and the first backup interface is G / EPON OLT optical interface #2. In the event of a communication interruption at G / EPON OLT optical interface #1, G / EPON OLT optical interface #2 will be used as the first target interface.

[0082] In addition, if there is no communication interruption at the first main interface, the first main interface is determined as the first target interface.

[0083] In step 405, the downlink signal is sent to the first target interface through the first uplink optical interface;

[0084] Once the first target interface is determined, the first uplink optical interface will send the downlink signal to the first target interface;

[0085] In step 405, the second communication interruption information of multiple second uplink optical interfaces is obtained through the optical router;

[0086] The aforementioned second uplink optical interface can be either a second primary interface or a second backup interface. Specifically, when the first target interface is the first primary interface, the second uplink optical interface is the second primary interface; when the first target interface is the first backup interface, the second uplink optical interface is the second backup interface. Additionally, it should be noted that in this step, the second communication interruption information can be obtained through the CPLD control unit in the optical router.

[0087] In step 406, based on the second communication interruption information, the second target interface is determined from the plurality of second uplink optical interfaces by the optical router;

[0088] In one embodiment, step 406 further includes:

[0089] If the second communication interruption information indicates that there is a communication interruption on the second main interface, the network management server determines that the second backup interface is the second target interface.

[0090] In this embodiment, if communication is interrupted at the second primary interface, it indicates a communication failure in the primary all-optical link, specifically at the second primary interface. Therefore, to ensure normal signal transmission from the optical gateway to the optical router, the second backup interface needs to be designated as the second target interface. If communication is not interrupted at the second primary interface, the second primary interface is designated as the second target interface.

[0091] Since the second backup interface is designated as the second target interface, but the second target interface is a backup all-optical link and cannot communicate with the primary all-optical link, the downlink signal needs to be transmitted through the backup all-off link instead of the primary all-optical link.

[0092] Therefore, in another embodiment, after determining the second target interface among the plurality of second uplink optical interfaces based on the second communication interruption information by the network management server, the method further includes:

[0093] Identify the backup all-optical link corresponding to the second target interface;

[0094] The first backup interface in the backup all-optical link is determined as the first target interface, and the step of sending the downlink signal to the first target interface through the first uplink optical interface is executed.

[0095] In this embodiment, since there may be multiple backup all-optical links, it is necessary to first determine the backup all-optical link where the second target interface is located, and then determine the first target interface from the backup all-optical links, so that the first uplink optical interface can transfer the downlink signal from the first primary interface in the primary all-optical link to the first backup interface in the backup all-optical link for transmission. Figure 2 As shown, for example, in the event of a communication interruption at G / EPON optical interface #1, G / EPON optical interface #2 is determined as the second target optical interface, and then G / EPON OLT optical interface #2 in the backup all-optical link where G / EPON optical interface #2 is located is determined as the first target interface, so that the 10G PON optical interface can send downlink signals to G / EPON OLT optical interface #2 for subsequent transmission.

[0096] In step 407, the downlink signal sent by the first target interface is received through the second target interface;

[0097] In step 408, the downlink signal is sent to multiple Ethernet ports through the second target interface.

[0098] After receiving the downlink signal, the second target interface sends the downlink signal to all Ethernet interfaces so that the external network devices connected to the Ethernet interfaces can receive the downlink signal and complete the signal transmission process.

[0099] In this embodiment, the above steps enable the formation of multiple links for transmitting downlink signals between the optical gateway and the optical router via the first uplink optical interface, the downlink optical interface, and the second downlink optical interface. The downlink signal can be transmitted through the normally functioning link based on the communication interruption information of each interface, effectively reducing the probability of service interruption caused by link blockage, reducing link maintenance costs, and improving the speed of fault detection and repair.

[0100] In one embodiment of this application, after sending the downlink signal to the first target interface through the first uplink optical interface, the method further includes:

[0101] Obtain the third communication interruption information of the second optical splitter through the optical gateway;

[0102] In the event that the third communication interruption information is interrupted, the first backup interface in the backup all-optical link to which the second optical splitter belongs is determined as the first target interface, and the step of sending the downlink signal to the first target interface through the first uplink optical interface is executed.

[0103] In this embodiment, to prevent signal transmission failure due to communication failure of the second optical splitter, it is also necessary to obtain the third communication interruption information of the second optical splitter, and if the third communication interruption information indicates an interruption, a new transmission link is selected. For example... Figure 2 As shown, for example, the optical link where the optical splitter #1.1 is located is normal; the downlink signal communicates through the optical link where the optical splitter #1.1 is located; the FTTR optical gateway determines whether there is an interruption in the communication of the optical link where the optical splitter #1.1 is located; if an interruption occurs, the downlink signal automatically switches to the optical link where the optical splitter #2.1 is located; if no interruption occurs, the communication still goes through the optical link where the optical splitter #1.1 is located.

[0104] In this embodiment, communication interruption problems caused by FTTR optical gateway and optical router equipment failures, optical splitter failures, link failures between optical gateway and optical splitter, and link failures between optical splitter and optical router can be effectively solved. It realizes primary and backup redundancy protection and self-healing switching on the FTTR optical gateway side, ODN optical link side, and FTTR optical router side. The switching latency is as low as milliseconds, which can basically achieve real-time hot switching and realize a true full protection mechanism.

[0106] The first receiving module 501 receives downlink signals sent by the metropolitan area network through the first uplink optical interface;
