Description

Technical Field

[0001] The present application relates to the field of optical communications, and in particular to a flow-dividing integrated processing system with a LAN port. Background Art

[0002] Optical protectors and convergence and diversion products are commonly used devices in communication networks, used to protect optical fiber lines and achieve data traffic convergence and diversion respectively. Although these devices play an important role in improving network performance and reliability, they also have some defects and shortcomings.

[0003] The installation and debugging process of the optical protector is relatively complicated and requires professional technicians to operate. The separation of the optical protector from the convergence and distribution products requires switches to be connected through the network and external jumpers to be connected. Different manufacturers have different definitions, which increases the complexity of the connection. Ordinary optical protectors can only detect optical power switching and cannot determine whether the original link is abnormal.

[0004] The connection of convergence and diversion products into the network in series poses a great challenge to the reliability of the network. Through linkage with the optical protector, a heartbeat keep-alive mechanism is involved. The optical protector must be interconnected through a switch, and an open API interface is required for docking. This involves the stability of the optical protector and the convergence and diversion matching, as well as the security of the API interface. Summary of the invention

[0005] One purpose of the present application is to provide an integrated splitter processing system with a LAN port, at least to solve the complex technical problems of installation and debugging of optical protectors and convergence splitters.

[0006] To achieve the above-mentioned objectives, some embodiments of the present application provide an integrated diversion processing system with a LAN port, including: an optical protector board, which is connected to a network device for optical power detection and switching protection; a convergence and diversion board, which is connected to the optical protector board for traffic convergence and diversion; the optical protector board is connected to multiple convergence and diversion boards through an optical fiber interface; a backplane, which is connected to the optical protector board and the convergence and diversion board through a physical interface; a logic control unit, which is connected to the backplane, and the optical protector board and the convergence and diversion board are connected to the logic control unit through a network interface through the backplane; and the operating status of the optical protector board and the convergence and diversion board are uniformly controlled.

[0007] Compared with the related technologies, in the solution provided by the embodiments of the present application, an optical protector and a converging and diverging device are integrated and connected through a backplane, removing the risks brought by switching and the security risks brought by open APIs. Moreover, the optical protector and the converging and diverging device can be centrally managed, reducing the implementation difficulty and the number of failure points, improving stability, quickly responding and timely adjusting the state of the optical protector, and effectively protecting the optical communication system.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0015] The embodiments of the present application relate to a diverting integrated processing system with a LAN port. As Figure 1 shown, the system includes:

[0016] An optical protector board, which is connected to a network device and is used for optical power detection and switching protection;

[0017] A converging and diverging board, which is connected to the optical protector board and is used for traffic convergence and divergence;

[0018] The optical protection board is connected to multiple said aggregation and diversion boards through optical fiber interfaces;

[0019] A backplane, the backplane is connected to the optical protection board and the aggregation and diversion boards through physical interfaces;

[0020] A logic control unit, the logic control unit is connected to the backplane, and through the backplane, the optical protection board and the aggregation and diversion boards are connected to the logic control unit through network interfaces; the operation states of the optical protection board and the aggregation and diversion boards are uniformly controlled.

[0021] The aggregation and diversion integrated processing system adopts a fully pluggable design and high-density boards. Among them, the optical protection board supports the protection of 4 links; the aggregation and diversion board supports the aggregation and diversion functions of multiple ports, and the traffic processing passes through the backplane switching processing module. A single aggregation and diversion integrated system supports 8 service slots and can be configured in various combinations. This embodiment is designed based on a 1+3 ratio combination, that is, one optical protection board corresponds to 3 aggregation and diversion boards, and at the same time, a link protection design is reserved. The optical protection board and the aggregation and diversion boards are connected to the backplane through physical interfaces, the backplane is connected to the logic control unit, and at the same time, the optical protection board and the aggregation and diversion boards are interconnected through the backplane with the switching processing module, and the operation of the entire system is controlled by a unified logic control unit; among them, the dotted line represents the network interface connection, and the solid line represents the optical fiber interface connection.

[0022] Further, the system includes: a first diversion processing module and a second diversion processing module, which respectively include an optical protection board, a first aggregation and diversion board, a second aggregation and diversion board, and a third aggregation and diversion board; the optical protection board is respectively connected to the first aggregation and diversion board, the second aggregation and diversion board, and the third aggregation and diversion board through optical fibers.

[0023] The system includes a first diversion processing module and a second diversion processing module, and each module adopts an independent 1+3 ratio configuration: each module includes 1 optical protection board (supporting 4-way optical link protection) and 3 aggregation and diversion boards (supporting multi-port traffic processing); the two modules together occupy 8 service slots (4 slots for each module), meeting the high-density design requirements of the system.

[0024] Connection between the optical protection board and the aggregation and diversion board: Each optical protection board is directly interconnected with three aggregation and diversion boards in this module through optical fibers. The specific connection method is: The S1 / S2 ports of the optical protection board are respectively connected to the P1 / P2 ports of the first aggregation and diversion board; the L1 / L2 ports of the optical protection board are respectively connected to the P1 / P2 ports of the second aggregation and diversion board; the N1 / N2 ports of the optical protection board are respectively connected to the P1 / P2 ports of the third aggregation and diversion board.

[0025] The core network devices (such as NE1 / NE2) are connected to the system through the L1 / L2 ports of the optical protector board, and are split to the corresponding aggregation and splitting boards through the S1 / S2 / N1 / N2 ports of the optical protector board. Finally, cross-board traffic forwarding is achieved through the backplane switching and processing module.

[0026] Each splitting and processing module communicates independently with the logic control unit through the backplane, supporting independent configuration of parameters such as optical power threshold and bit error rate detection strategy; the logic control unit synchronizes the states of the two modules through an internal heartbeat mechanism to achieve dual-module redundant protection (such as automatically switching to another module in case of single-module failure); the aggregation and splitting boards of the two modules can cooperate to process traffic, supporting dynamic load balancing or traffic distribution based on service types.

[0027] The system supports flexible deployment of single-module or dual-module, and can select to enable a single 1+3 module (occupying 4 slots) or dual-module (fully configured with 8 slots) according to actual needs; the optical protector board and the aggregation and splitting boards support hot plugging, and the optical module interfaces are compatible with standard interfaces such as SFP+ / QSFP28, facilitating later upgrades or replacements.

[0028] Furthermore, as Figure 2 shown, the optical protector board includes: the NE1 / NE2 ports of the optical protector board are respectively fiber-connected to the first network device (core network NE1) and the second network device (core network NE2); the L1 / L2 ports of the optical protector board are respectively fiber-connected to the P1 / P2 ports of the first aggregation and splitting board; the N1 / N2 ports of the optical protector board are respectively connected to the S2 / S1 ports of the optical protector board; where the S1 / S2 / L1 / L2 / P1 / P2 ports are all optical module interfaces.

[0029] The NE1 port of the optical protector board is bidirectionally connected to the core network NE1 through a fiber: the Tx pin of the NE1 port is fiber-docked with the Rx pin of the core network NE1, and the Rx pin of the NE1 port is interconnected with the Tx pin of the core network NE1 to achieve bidirectional transmission of service data. Similarly, the NE2 port is fiber-connected to the core network NE2 in the same way to build the basic communication link between the core network and the optical protector board, providing a stable channel for the access and output of service data.

[0030] The L1 port of the optical protector board is precisely fiber-docked with the P1 port of the first aggregation and splitting board: the Tx of the L1 port is connected to the Rx of the P1 port, and the Rx of the L1 port is connected to the Tx of the P1 port to ensure the unidirectional transmission path of the optical signal. The L2 port is interconnected with the P2 port of the first aggregation and splitting board following the same logic, enabling the traffic processed by the optical protector board to be stably transmitted to the aggregation and splitting board, performing the aggregation or splitting operation of multi-port traffic, and achieving refined data processing.

[0031] The N1 port and the S2 port of the optical protector board form an internal loop through an optical fiber: the Tx of the N1 port is connected to the Rx of the S2 port, and the Rx of the N1 port is connected to the Tx of the S2 port; the N2 port and the S1 port also complete the optical fiber connection. This loop is used for the self-detection of the optical protector board. By sending and monitoring the backhaul signal, it verifies the optical module interface status, optical link connectivity, and signal quality, providing an underlying guarantee for the system reliability. Among them, S1 / S2 / L1 / L2 / P1 / P2 are all optical module interfaces, and the optical modules on the ports can be plugged and unplugged.

[0032] Furthermore, as Figure 3 shown, the connection method of the optical protector board with the second aggregation and splitting board and the third aggregation and splitting board is the same as that of the first aggregation and splitting board.

[0033] The 4 groups of links of the optical protector board all adopt the same design logic. Among the other 3 groups of links, for each group of ports such as NE3 / NE4, L3 / L4, etc., they are respectively connected to the corresponding core network device and the aggregation and splitting board port, and the internal N3 / N4 and S3 / S4 and other ports also form a detection loop. Each link contains a port combination similar to "NE1 / NE2 / L1 / L2 / N1 / N2 / S2 / S1". Through a standardized connection method, it ensures the consistency of each link in functions such as optical protection, traffic transmission, and status detection, facilitating the unified management and maintenance of the system.

[0034] For each aggregation and splitting board, only two ports (such as P1 / P2) need to be connected to the optical protector board. These two ports achieve traffic cross-forwarding through the backplane switching processing module: when the P1 port of the aggregation and splitting board receives data from the optical protector board, through the internal scheduling of the backplane switching processing module, the traffic can be flexibly forwarded to other ports (such as P3 - P6), or interact with the traffic of the P2 port. The backplane switching processing module, as the core hub, supports the traffic scheduling strategy between multiple ports, meeting the diverse requirements of the aggregation and splitting board for the aggregation, splitting, forwarding, etc. of different service flows, and finally realizing the overall high-efficiency data processing ability of the system.

[0035] The connection unity of the optical protector board with the second and third aggregation and splitting boards, the connection of the optical protector board with the second aggregation and splitting board reuses the logic of the first aggregation and splitting board: for example, the L3 / L4 ports of the optical protector board are connected to the P1 / P2 ports of the second aggregation and splitting board through optical fibers, and the internal loop detection ports are also interconnected according to the same rules. The connection with the third aggregation and splitting board is the same. This standardized design simplifies the system installation and debugging process, reduces the maintenance difficulty, guarantees the scalability and stability of the system, and facilitates the quick replacement of faulty boards.

[0036] Further, controlling the operating states of the optical protector board and the aggregation and diversion board includes:

[0037] When the optical power detection of S1-RX or S2-RX of the optical protector board is lower than the first threshold, switch to the bypass state;

[0038] When the optical power detection of L1-RX or L2-RX of the optical protector board is lower than the second threshold, switch to the bypass state;

[0039] When the optical power detection of P1-RX or P2-RX of the first aggregation and diversion board is lower than the third threshold, switch to the bypass state;

[0040] When the bit error rate detected at the P1 / P2 port of the first aggregation and diversion board or the S1 / S2 port of the optical protector board reaches the fourth threshold, switch to the bypass state;

[0041] When the traffic detected at the P1 / P2 port of the first aggregation and diversion board or the S1 / S2 port of the optical protector board drops to the fifth threshold, switch to the bypass state;

[0042] When there is an abnormality in the optical protector board, the aggregation and diversion board, or the internal communication heartbeat, switch to the bypass state.

[0043] When the optical power detection value of the S1-RX or S2-RX port of the optical protector board is lower than the first threshold, it indicates that the upstream signal power received by the optical protector board is insufficient, and there may be problems such as a broken optical fiber link, a malfunction of the optical module, or abnormal light emission from the peer device. At this time, the system determines that the input link of the optical protector board is abnormal and triggers a bypass switch to avoid data transmission errors caused by weak signals.

[0044] Similarly, if the optical power of the L1-RX or L2-RX port is lower than the second threshold, it indicates that the optical power of the connection link between the optical protector board and the aggregation and diversion board is abnormal. To ensure uninterrupted service, the system immediately switches to the bypass state.

[0045] Monitoring the input port of the aggregation and diversion board. For the P1-RX or P2-RX port of the first aggregation and diversion board, when the optical power detection is lower than the third threshold, it indicates that the optical signal power received by the aggregation and diversion board is insufficient, which may affect subsequent traffic processing. By continuously monitoring the optical power of such ports in real time, the system quickly switches to the bypass state when an abnormality occurs to maintain direct communication between core network devices.

[0046] When the bit error rate exceeds the standard and triggers bypass switching, when the bit error rate detected at the P1 / P2 ports of the first aggregation and diversion board or the S1 / S2 ports of the optical protector board reaches the fourth threshold, it means that the link transmission quality has seriously deteriorated and the data error rate exceeds the acceptable range. The excessive bit error rate may be caused by factors such as excessive optical link noise, deteriorated optical module performance, or the transmission distance exceeding the adaptation range of the optical module. At this time, the system determines that the current link can no longer ensure accurate data transmission, and immediately switches to the bypass state to isolate the faulty link and ensure smooth business between core network devices.

[0047] When traffic anomalies trigger bypass switching, if the traffic detected at the P1 / P2 ports of the first aggregation and diversion board or the S1 / S2 ports of the optical protector board drops to the fifth threshold, it indicates that there may be situations such as service interruption, abnormal port negotiation, or abnormal upper-layer service shutdown on the link. The system triggers bypass switching when the traffic anomaly decreases by real-time monitoring of the port traffic changes, avoiding long-term service interruption caused by traffic anomalies.

[0048] When device and communication status anomalies trigger bypass switching, when hardware failures occur in the optical protector board or the aggregation and diversion board itself (such as chip anomalies, power module failures), or internal communication heartbeat signals are abnormal (such as the loss of heartbeat signals between the logic control unit and the board, or the heartbeat period exceeding the set range), the system determines that the device operating state or the internal communication link is abnormal. To prevent the spread of faults from affecting core services, the system immediately switches to the bypass state to ensure basic communication between core network devices, and at the same time provides a time window for fault troubleshooting and repair.

[0049] Among them, the selection of the threshold can be set accordingly according to the quality requirements of the actual communication network. Through the above multi-dimensional monitoring and precise triggering mechanism, the system can quickly switch to the bypass state in scenarios such as abnormal optical power, excessive bit error rate, traffic anomalies, and device status failures, effectively improving the reliability and service continuity of the network, and meeting the requirements of high-stability communication scenarios.

[0050] Furthermore, as Figure 4 shown, the bypass state includes:

[0051] Forward the data of the NE2-Rx port of the second network device to the NE1-Tx port of the first network device;

[0052] Forward the data of the NE1-Rx port of the first network device to the NE2-Tx port of the second network device.

[0053] In the bypass state, the system ensures the physical connection between core network devices by reconstructing the data transmission path, minimizing the impact of faults on services. The specific working mechanism is as follows:

[0054] Data flow reconstruction, the optical protector single board realizes the direct connection and switching between core network NE1 and NE2: The receiving end of core network NE2 (NE2-Rx) data no longer passes through the conventional processing path of the optical protector single board (such as from L1 / L2 ports to P1 / P2 ports of the aggregation and diversion single board), but directly through the switching mechanism inside the optical protector single board, and is transferred to the sending end of core network NE1 (NE1-Tx). It bypasses the ports of the optical protector single board and the links of the aggregation and diversion single board that may have faults, forming a direct path.

[0055] Similarly, the data of the receiving end of core network NE1 (NE1-Rx) is directly transferred to the sending end of core network NE2 (NE2-Tx) through the fast switching logic inside the optical protector single board. Through the reconstruction of this two-way data path, a fiber physical direct connection channel is established between core network NE1 and NE2 to ensure that basic communication is not interrupted.

[0056] In the bypass state, the system isolates the faulty ports of the optical protector single board (such as S1 / S2 / L1 / L2 ports), the links of the aggregation and diversion single board, etc. from the main communication path. For example, if the optical power of the L1-Rx port is lower than the threshold and bypass is triggered, the communication between NE1 and NE2 no longer depends on this faulty port, avoiding the continuous impact of the fault on the service.

[0057] Through the establishment of fast switching of the direct connection path, the bypass state ensures the continuous transmission of service data between core network NE1 and NE2. Even if the optical protector single board or the aggregation and diversion single board fails, key services such as voice, video, and data transmission can still maintain basic operation, meeting the high reliability requirements of the communication system.

[0058] The essence of the bypass state is to restore the fiber physical direct connection between core network NE1 and NE2. This underlying physical connection method is not affected by upper-layer protocols and device processing logics and has the highest-priority communication guarantee ability. Even if there are abnormalities in the upper-layer software of the system, the physical direct connection path can still remain unobstructed, buying time for fault troubleshooting and repair.

[0059] Furthermore, the logic control unit includes:

[0060] When the logic control unit detects that the states of the optical protector single board and the aggregation and diversion single board are normal, it controls the optical protector single board and the aggregation and diversion single board to maintain the cascaded state;

[0061] In the cascaded state, it real-time detects the state data of the optical protector single board and the aggregation and diversion single board, and automatically configures the heartbeat state of the corresponding single board;

[0062] According to the heartbeat state, it detects the optical power, traffic, and bit error rate of the ports of the optical protector single board and the ports of the aggregation and diversion single board.

[0063] When working normally, it switches to the cascaded state. The logic control unit during cascading will detect in real time whether the single board is abnormal, automatically configure the corresponding heartbeat status, and the internal heartbeat can ensure the secure transmission of control signals through VLAN division, detect the optical power of the aggregation and diversion ports and the port traffic status, count the bit error rate and the traffic decline status, and detect the optical power status of the optical protector port. The traffic detection interface of the port is integrated in the centralized switching and processing module unit, and the logic control unit implements the entire switching control logic, which can achieve a fast switching mechanism to ensure timely switching to the bypass when an abnormal situation occurs.

[0064] Furthermore, the cascaded state is as Figure 5 shown, including:

[0065] Forward the data of the NE1-Rx port of the first network device to the NE1-Tx port of the first network device; forward the data of the NE1-Tx port of the first network device to the S2-RX port of the optical protector single board;

[0066] Forward the data of the S2-RX port of the optical protector single board to the L1-TX port of the optical protector single board, and the optical fiber is connected to the P1 / P2 ports of the aggregation and diversion single board;

[0067] Forward the data of the P1-Rx port of the aggregation and diversion single board to the P2-Tx port;

[0068] Forward the data of the P2-Rx port of the aggregation and diversion single board to the P1-Tx port;

[0069] The first flow direction of the traffic in the system is NE1-Rx to N1-Tx to S2-Rx to L1-Tx to P1-Rx to P2-Tx to L2-Rx to S1-Tx to N2-Rx to N2-Tx;

[0070] The second flow direction of the traffic in the system is NE2-Rx to N2-Tx to S1-Rx to L2-Tx to P2-Rx to P1-Tx to L1-Rx to S2-Tx to N1-Rx to N1-Tx;

[0071] Among them, the solid line is the optical fiber connection, and the virtual is the connection through the backplane passing through the centralized switching and processing unit.

[0072] When in the series state, the data flow direction starting from NE1-Rx includes that the data received by the receiving end (NE1-Rx) of the core network device NE1 is first transmitted to the N1-Tx port of the optical protector single board. This is the starting point for the data to enter the system processing flow, and the optical protector single board begins to perform preliminary monitoring and processing preparation on the data.

[0073] The internal transmission of the optical protector board includes that the data of the N1-Tx port is then transmitted to the S2-Rx port, ensuring that the data can be smoothly transferred from one interface to the interface connected to the aggregation and diversion board. The data from the S2-Rx port of the optical protector board to the aggregation and diversion board is then transmitted to the L1-Tx port and then connected to the P1 port of the aggregation and diversion board through an optical fiber. This step realizes the data interaction between the optical protector board and the aggregation and diversion board, introducing the data from the optical protection link to the aggregation and diversion processing link.

[0074] The internal traffic cross of the aggregation and diversion board includes that after receiving the data of the P1-Rx port, according to the internal traffic cross rule, the data is transferred from the P1-Rx port to the P2-Tx port. The data returned from the aggregation and diversion board to the optical protector board includes that the data of the P2-Tx port is transmitted to the L2-Rx port of the optical protector board through an optical fiber, and then passes through S1-Tx and N2-Rx in sequence and finally reaches the N2-Tx port. This series of transmission processes completes the return path of the data after aggregation and diversion processing, enabling the data to return to the core network device or continue subsequent processing.

[0075] The data flow in the starting direction of NE2-Rx includes from the core network to the optical protector board. The data received by the receiving end (NE2-Rx) of the core network device NE2 is transmitted to the N2-Tx port of the optical protector board to start the data processing process. The internal transmission of the optical protector board includes that the data of the N2-Tx port is transferred to the S1-Rx port to prepare for the connection with the aggregation and diversion board.

[0076] The data transmission from the optical protector board to the aggregation and diversion board includes that the data of the S1-Rx port is transmitted to the L2-Tx port and connected to the P2 port of the aggregation and diversion board through an optical fiber. The internal traffic cross of the aggregation and diversion board includes that the aggregation and diversion board transfers the data of the P2-Rx port to the P1-Tx port to realize the aggregation and diversion operations of the data. The data of the P1-Tx port is transmitted to the L1-Rx port of the optical protector board through an optical fiber, and then passes through S2-Tx and N1-Rx in sequence and finally reaches the N1-Tx port to complete the data transmission and processing cycle.

[0077] That is, the traffic differentiates two directions. One direction is NE1-Rx to N1-Tx to S2-Rx to L1-Tx to P1-Rx to P2-Tx to L2-Rx to S1-Tx to N2-Rx to N2-Tx, and the other direction is NE2-Rx to N2-Tx to S1-Rx to L2-Tx to P2-Rx to P1-Tx to L1-Rx to S2-Tx to N1-Rx to N1-Tx.

[0078] The cascaded state realizes the collaborative work among core network devices, optical protector boards, and aggregation and diversion boards through reasonable data flow planning and connection methods. It can effectively aggregate and divert data, improving the efficiency and flexibility of data transmission. At the same time, through the monitoring and protection functions of the optical protector board, abnormal situations in the data transmission process can be detected and processed in a timely manner, ensuring the stability and reliability of the system. In practical applications, the cascaded state can be widely applied to various communication networks and data processing systems to meet the data transmission and processing requirements in different service scenarios.
