Obviously, the drawings in the following description are only some embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0025] Figure 2 is the second association schematic diagram of the end-to-end tandem management system provided by the embodiments of the present application. Detailed Embodiments

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0027] In the description and claims of this application, terms such as "first" and "second" are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the structures used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0028] In the field of network technology, domain partitioning generally refers to dividing a large network into multiple smaller, more manageable and controllable sub-networks or regions. The implementation of domain partitioning takes into account multiple factors such as network architecture, business requirements, security requirements, performance goals, and technical standards. By reasonably partitioning the domain, the overall performance, flexibility, and scalability of the network can be improved, and at the same time, it also helps to enhance network security and management efficiency. In end-to-end communication, domain partitioning involves different network regions and service domains along the entire path from the user terminal to the service provider network. In the home customer end-to-end scenario, the network can be divided into three domains: the user side, the access side, and the metropolitan area network, and each domain is responsible for handling specific network functions or services.

[0029] An end-to-end tandem management system is provided in an embodiment of this application, as Figure 1 shown, including: a user equipment (User Equipment, UE), an optical network unit (Optical Network Unit, ONU), a passive optical splitter (Passive Optical Splitter, POS), an optical line terminal (Optical Line Terminal, OLT), and a metropolitan area network device, where the metropolitan area network device includes at least one of a server router (Server Router, SR) and a broadband remote access server (Broadband Remote Access Server, BRAS);

[0030] The OLT is connected to the metropolitan area network device through a first uplink, the metropolitan area network device is connected to the metropolitan area side network, an association relationship between the SR and the OLT is established in the SR, and an association relationship between the BRAS and the OLT is established in the BRAS;

[0031] The OLT is connected to the ONU through the POS, an association relationship between the OLT and the POS is established in the OLT, and an association relationship between the POS and the ONU is established in the POS;

[0032] The ONU is connected to the UE, and an association relationship between the ONU and the UE is established in the ONU.

[0033] Among them, the UE is deployed on the user side. The UE can be a device directly used by the user, such as a computer, a smart phone, a tablet computer, and a smart home device. Based on the UE, a customer number and a broadband account can be obtained on the user side. The UE is the origin and destination of data. The user can access Internet services or control the smart system at home through the UE, realizing the connection between the user and the broadband service.

[0034] The ONU, POS, and OLT are deployed on the access side. The ONU is connected to the UE to synchronize the broadband account. Based on the ONU, POS, and OLT, information such as the broadband account, ONU port, ONU device, ONU name, OLT PON port, OLT IP, OLT device, splitter port, and virtual local area network (VLAN) can be obtained on the access side. Among them, the ONU can be a device close to the user side in the fiber optic network, responsible for converting the optical signal transmitted in the fiber into an electrical signal for use by the user terminal device. The ONU is usually installed in a user's residence or commercial building and is the first station for the user to access the fiber optic network. The POS is a passive device used to distribute the optical signal sent by the OLT to multiple ONUs, realizing a one-to-many network structure. In this way, one OLT can serve multiple users, improving the efficiency and scalability of the fiber optic network. The OLT is a device close to the service provider side in the fiber optic network, responsible for converting the user's electrical signal into an optical signal and sending it out through the fiber optic network. At the same time, the OLT can also receive the optical signal from the ONU and convert it back into an electrical signal for further processing. The OLT is a bridge connecting users to the metropolitan area network or a wider Internet.

[0035] The metropolitan area network device is deployed in the Metropolitan Area Network (MAN). The metropolitan area network device can include at least one of the SR and BRAS. The OLT device is connected to the metropolitan area network device through a first uplink. Based on the SR and BRAS, information such as the BRAS name, BRAS IP, and SR information can be obtained in the metropolitan area network. The metropolitan area network is a high-speed network covering a city or a certain area and can connect multiple local area networks and the networks of Internet service providers. The BRAS is a network device used to provide broadband access services. In the metropolitan area network, the BRAS can be responsible for tasks such as user authentication, billing, and bandwidth allocation and is a key component for users to access Internet services. The SR is a high-performance network router that can be used in the core part of a data center or a large network. The SR can be responsible for high-speed data transmission and routing to ensure the efficient transmission of data packets from the source to the destination.

[0036] Among them, the customer side is associated with the access side through a broadband account. The connection methods between the OLT deployed on the access side and the BRAS deployed in the metropolitan area network may include:

[0037] Direct connection: The OLT and the BRAS can be directly connected through optical fibers. This method is applicable to the situation where the OLT and the BRAS are located in the same computer room or in close proximity. Through the aggregation layer device: In the case where the OLT and the BRAS are not in the same computer room or are far apart, they can be connected through an aggregation layer device (such as a Packet Transport Network (PTN), an aggregation switch, etc.). This method can perform bandwidth and port aggregation to meet different network requirements. Through protocol connection: The communication between the OLT and the BRAS may involve multiple network protocols, including but not limited to the Link Layer Discovery Protocol (LLDP) for device discovery and topology management at the link layer, and other protocols for ensuring data transmission and network management, such as Figure 2 shown.

[0038] It should be understood that the connection methods between the OLT deployed on the access side and the SR deployed in the metropolitan area network can also include direct connection, connection through the aggregation layer device, and connection through the protocol. Details are not described herein again.

[0039] In the embodiments of the present application, an end-to-end cascading management system is provided. In the user side, access side, and metropolitan area network of the home broadband end-to-end scenario, while each domain processes specific network functions or services, through the cascading association relationships in sequence among the UE, ONU, POS, OLT, and metropolitan area network devices, the relatively independent user side, access side, and metropolitan area network originally caused by domain autonomy can be associated in sequence. In this way, the UE can perform cross-domain data collection, realizing comprehensive monitoring and management of the UE, ONU, POS, OLT, and metropolitan area network devices, and ensuring that users can clearly understand and control the entire link of their broadband services. When a network failure occurs, users can quickly and accurately locate the location of the failure according to the cross-domain established association relationship, shortening the time for troubleshooting.

[0040] Optionally, the target detection device is used to send the obtained status information of the first device to the second device. The first device is the upper-level device associated with the target detection device, the second device is the lower-level device associated with the target detection device, and the target detection device is any one of the ONU, the POS, and the OLT.

[0041] In this embodiment, the status information includes the life cycle status of the first device, such as "demolition", "off-net", "scrap", etc. The target detection device realizes full-link real-time monitoring by transmitting the status information of the first device (i.e., the upstream device) across levels to the second device (i.e., the downstream device). When a network failure occurs, the user can quickly and accurately locate the location of the failure according to the status information and through the association relationship established across domains, shortening the time for troubleshooting.

[0042] Exemplarily, the status information may further include other information, such as parameters such as output optical power and wavelength. Taking the target detection device as a POS as an example, an exemplary description is given. The POS can monitor status information such as the output optical power and wavelength of the OLT in real time through a built-in optical power sensor; when the optical power of the PON port of the OLT is lower than the threshold (such as -3dBm), the POS triggers an alarm and records the abnormal timestamp; the POS synchronizes the status information of the upstream device to the downstream ONU. In this way, the location of the failure can be quickly and accurately located according to the established association relationship, shortening the time for troubleshooting.

[0043] It should be understood that when the target detection device is other devices, the same technical effects can be achieved. To avoid repetition, it will not be elaborated here.

[0044] Optionally, the association relationship between the ONU and the UE is an association relationship established based on broadband services.

[0045] In this example, first, the UE is associated with the broadband service, and the status information of the broadband service is not "demolished". The access methods of the broadband service mainly include Fiber To The Home (FTTH) and Fiber To The Building (FTTB). FTTH provides users with a higher level of personalized services and network experience, while FTTB is suitable for multi-user environments. Then, when the access methods are FTTH and FTTB, the ONU / Optical Network Terminal (ONT) to which the broadband service belongs is associated with the ONU. ONU / ONT is the key equipment for the implementation of the broadband service. They are responsible for converting optical signals into electrical signals that user equipment can process, and providing functions such as network interfaces, bandwidth management, and fault diagnosis. With the development of technology, the functions of ONU / ONT are also constantly enhanced to meet users' demands for high-speed, stable, and diverse network services. In this way, the association relationship between the ONU and the UE based on the broadband service is established. The relatively independent user side and access side caused by domain autonomy can be associated in sequence, enabling the UE to perform cross-domain data collection, and further realizing the comprehensive monitoring and management of the UE, ONU, POS, OLT, and metropolitan area network devices, ensuring that users can clearly understand and control the entire link of their broadband services. When a network failure occurs, users can quickly and accurately locate the location of the failure according to the cross-domain established association relationship, shortening the time for troubleshooting.

[0046] Among them, in the fiber broadband network, the upstream device of the ONU is associated with the POS, or the upstream device port of the ONU is associated with the POS port, the splitter to which the POS port belongs is associated with the corresponding splitter, and the life cycle status of the ONU is not "withdrawal from the network". The ONU and the POS together constitute the basic architecture of the Passive Optical Network (PON) network, realizing efficient and reliable broadband access services. The use of splitters reduces the complexity and cost of the network, while improving the scalability and flexibility of the network.

[0047] Optionally, the POS is connected to the OLT through a second upstream link, and the POS is also connected to the OLT through a second upstream optical path. The second upstream link is an electrical signal transmission link, and the second upstream optical path is an optical signal transmission link.

[0048] In an example, the POS can be connected to the OLT through a second upstream link. The second upstream link is an electrical signal transmission link, and the association relationship between the OLT and the POS is established in the OLT. As the core of the network, the OLT ensures the stable transmission of signals and the continuity of network services through its close association with the POS.

[0049] In another example, a second upstream optical path is added to the end-to-end cascaded management system. The second upstream optical path refers to the optical fiber connection path from the POS to the OLT in optical fiber communication. The second upstream optical path includes the optical fiber itself and possible connection hardware such as optical fiber connectors and splitters to comprehensively improve the overall performance of the network. Specifically, based on the connection between the POS and the OLT through the second upstream link, further, the POS is also connected to the OLT through the second upstream optical path, that is, the A-end device or Z-end device of the second upstream optical path is associated with the OLT, and the second upstream optical path is associated with the second upstream link. End-to-end verification of connectivity (non-transmission service) can be performed through the second upstream optical path. In the non-transmission service scenario, the OLT is connected through the second upstream optical path, and end-to-end connectivity verification is performed to ensure the reliability and efficient operation of the optical communication network.

[0050] Optionally, the POS includes a first sub-POS (i.e., a primary splitter) and a second sub-POS (i.e., a secondary splitter);

[0051] When the first sub-POS is connected to the ONU, a third sub-association relationship between the first sub-POS and the ONU is established in the first sub-POS;

[0052] When the first sub-POS is connected to the ONU through the second sub-POS, a fourth sub-association relationship between the first sub-POS and the second sub-POS is established in the first sub-POS, and a fifth sub-association relationship between the second sub-POS and the ONU is established in the second sub-POS;

[0053] The association relationship between the POS and the ONU includes the third sub-association relationship, the fourth sub-association relationship, and the fifth sub-association relationship.

[0054] In one example, when the first sub-POS is connected to the ONU, a third sub-association relationship between the first sub-POS and the ONU is established in the first sub-POS. Specifically, the upstream device of the first sub-POS is associated with the OLT, or the primary port of the upstream device of the first sub-POS is associated with the OLT port, the transmission network element to which the OLT port table belongs is associated with the OLT, and the life cycle status of the OLT and the first sub-POS is not "withdrawn from the network".

[0055] In another example, when the first sub-POS is connected to the ONU through the second sub-POS, a fourth sub-association relationship between the first sub-POS and the second sub-POS is established in the first sub-POS, and a fifth sub-association relationship between the second sub-POS and the ONU is established in the second sub-POS. Specifically, the uplink device of the second sub-POS is associated with the first sub-POS, the uplink device of the first sub-POS is associated with the OLT, or the primary port of the uplink device of the first sub-POS is associated with the OLT port, the belonging transmission network element of the OLT port table is associated with the OLT, and the lifecycle status of the OLT and the optical splitter is not "withdrawn from the network".

[0056] In this way, through this hierarchical optical splitter structure, the PON network can efficiently manage and allocate broadband resources while maintaining network scalability and flexibility. As the core of the network, the OLT ensures stable signal transmission and network service continuity through its close association with the optical splitter.

[0057] Optionally, the OLT is associated with either the A-end network element or the Z-end network element of the first uplink link, and the other end of the A-end network element and the Z-end network element of the first uplink link is associated with the metropolitan area network device.

[0058] In this example, the first uplink link refers to the link connecting the OLT to a higher-level network node. The network element type of the OLT is "OLT" or "PON". The A-end (Active end) network element or the Z-end (Zapping end) network element of the first uplink link is associated with the OLT, and the lifecycle status is not "withdrawn from the network". In the first uplink link, the A-end network element or the Z-end network element refers to the link endpoint directly connected to the OLT. Maintaining the non-withdrawn status of the OLT and its uplink link is crucial for maintaining service continuity and user satisfaction. The other end of the A-end network element and the Z-end network element of the first uplink link is associated with the metropolitan area network device. The device level of the metropolitan area network device is "BRAS" or "Switch (SW)" or "SR", and the lifecycle status is not "withdrawn from the network" and "scrapped". The device level of the metropolitan area network device refers to the position and role of the device in the network architecture. BRAS, SW, and SR are common device types in the bearer network. BRAS is usually used at the edge of the broadband network to provide functions such as user authentication, billing, and bandwidth management. SW is used for high-speed forwarding of data packets and is one of the core devices in the network. SR is used for data transmission and routing functions in the metropolitan area network. Through this association, the efficient operation of the network and service quality are ensured.

[0059] Optionally, the first uplink link includes a first sub-link and a second sub-link. The OLT is associated with the BRAS through the first sub-link, and the OLT is associated with the SR through the second sub-link.

[0060] In this example, the first upstream link is divided into a first sub-link and a second sub-link. The OLT is associated with the BRAS through the first sub-link, and the OLT is associated with the SR through the second sub-link. In this way, even if one link fails, the other link can still maintain network connectivity, improving the stability of the system.

[0061] Optionally, a switch SW is also deployed on the second sub-link. The SR is connected to the OLT through the SW. A first sub-association relationship between the SR and the SW is established in the SR, and a second sub-association relationship between the SW and the OLT is established in the SW. The association relationship between the SR and the OLT includes the first sub-association relationship and the second sub-association relationship.

[0062] In this example, when the OLT and the SR are not in the same computer room or are far apart, they can be connected through aggregation layer devices (such as aggregation switches, etc.). This method can perform bandwidth and port aggregation to meet different network requirements. Specifically, the SW is deployed on the second sub-link. The SR is connected to the OLT through the SW. A first sub-association relationship between the SR and the SW is established in the SR, and a second sub-association relationship between the SW and the OLT is established in the SW. The association relationship between the SR and the OLT includes the first sub-association relationship and the second sub-association relationship. The originally relatively independent access side and metropolitan area network due to domain autonomy can be associated in sequence, enabling the OLT to perform cross-domain data collection, and then realizing comprehensive monitoring and management of UE, ONU, POS, OLT, and metropolitan area network devices, ensuring that users can clearly understand and control the entire link of their broadband services. When a network failure occurs, users can quickly and accurately locate the location of the failure based on the cross-domain established association relationship, shortening the time for troubleshooting.

[0063] Among them, the aggregation switch SW is used to carry the OLT and its service access, and adopts a stacking mode to logically combine two physical devices into one device.

[0064] In addition, in another example, the OLT upstream can also adopt the method of direct fiber optic connection. Direct fiber optic connection means that the OLT is directly connected to the metropolitan area network side through optical fibers without passing through any intermediate transmission devices.

[0065] In addition, in yet another example, the OLT upstream can also adopt a dual upstream method that combines transmission and direct fiber optic connection to access the metropolitan area network. Transmission means that the OLT is connected to the metropolitan area network device through the first upstream link, and the metropolitan area network device is connected to the metropolitan area network side. The dual upstream provides network redundancy, and even if one link fails, the other link can still maintain network connectivity.

[0066] Optionally, the OLT is also connected to the metropolitan area network device through a first uplink optical path. The first uplink link is an electrical signal transmission link, and the first uplink optical path is an optical signal transmission link.

[0067] In this example, a first uplink optical path is added to the end-to-end tandem management system. The first uplink optical path refers to the optical fiber connection path from the OLT to the metropolitan area network device in optical fiber communication. The first uplink optical path includes the optical fiber itself and possible connection hardware such as optical fiber connectors and splitters to comprehensively improve the overall performance of the network. Specifically, on the basis of the OLT being connected to the metropolitan area network device through the first uplink link, further, the OLT is also connected to the metropolitan area network device through the first uplink optical path, that is, the A-end device or Z-end device of the first uplink optical path is associated with the metropolitan area network device, and the first uplink optical path is associated with the first uplink link. End-to-end verification of connectivity (non-transmission services) can be performed through the first uplink optical path. In non-transmission service scenarios, through optical path connectivity verification, service providers can ensure the stability and reliability of the optical fiber network, identify and solve problems in a timely manner, and thus provide high-quality services to end users.

[0068] Optionally, the OLT is associated with either the A-end network element or the Z-end network element of the first uplink optical path, and the other end of the A-end network element and the Z-end network element of the first uplink optical path is associated with the metropolitan area network device.

[0069] In this example, on the basis of connecting the OLT to the link of a higher-level network node, the OLT is associated with either the A-end network element or the Z-end network element of the first uplink optical path, and the other end of the A-end network element and the Z-end network element of the first uplink optical path is associated with the metropolitan area network device, and the lifecycle status is not "withdrawal from the network". The relatively independent access side and metropolitan area network caused by domain autonomy can be associated in sequence, so that the OLT can perform cross-domain data collection, and then realize the comprehensive monitoring and management of UE, ONU, POS, OLT and metropolitan area network devices, ensuring that users can clearly understand and control the entire link of their broadband services. When a network failure occurs, users can quickly and accurately locate the location of the failure according to the cross-domain established association relationship, shortening the time for troubleshooting.
