Description

Technical Field

[0001] One or more embodiments of the present disclosure relate to the field of optical communication network technology, and in particular to a method, system, electronic device, and storage medium for self-healing of an on-chip optical network node failure. Background Art

[0002] With the rapid development of integrated circuit technology, the number of transistors integrated on a chip has exploded, driven by Moore's Law. This has led to a sharp increase in the demand for data transmission within the chip. The traditional on-chip bus architecture is limited by bandwidth bottlenecks and high power consumption, and it is difficult to meet the growing communication requirements. In this context, photonics technology has become a key path to break through the difficulties of internal chip communication with its high bandwidth, low latency and excellent anti-electromagnetic interference capabilities. Optical Network-on-Chip (ONoC) has emerged. It uses optical signals for data transmission, providing a new mechanism for internal chip communication. It can achieve long-distance, high-speed communication within a single package system, significantly reducing latency and power consumption. It has shown great potential in application scenarios such as multi-core processors and high-performance computing, and is gradually becoming the focus of industry research. Its development is of great significance to meeting the challenges of complex multi-core system design in the future.

[0003] However, current topology fault-tolerance technologies for on-chip optical networks generally lack the ability to adaptively adjust to diverse network topologies, performing poorly in real-time fault detection and dynamic response, and failing to meet the stringent requirements for high reliability and durability in complex network environments. Furthermore, these technologies primarily focus on path decision-making, aiming to improve data transmission efficiency, but ignore the frequent node failures in actual network operations. They fail to develop efficient and reliable self-healing methods for node failure scenarios, making it difficult for networks to quickly resume normal operations in the face of failures, severely impacting network stability and service continuity.

[0004] Therefore, it is urgent to develop an on-chip optical network topology self-healing technology that can adapt to different topologies, have rapid self-healing capabilities, and achieve effective dynamic response and adaptive adjustment when nodes fail. Summary of the Invention

[0051] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0052] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of the present disclosure should have the usual meanings understood by people with ordinary skills in the field to which the present disclosure belongs.

[0053] The self-healing method for an on-chip optical network node failure according to one or more embodiments of the present disclosure is applied to Figure 2 The self-healing system for on-chip optical network node failure shown includes a data monitoring module, a fault detection module, a self-healing strategy determination module and a self-healing strategy operation module.

[0054] This system is implemented within a communications architecture encompassing the aforementioned system, signaling layer, and optical network layer. The signaling layer, controlled by the aforementioned system, includes electrical router nodes and electrical channels. The optical network layer includes service generation modules, optical router nodes, transmission waveguides, and E / O and O / E converters.

[0055] refer to Figure 1 , the method comprises the following steps:

[0056] Step S101: The data monitoring module obtains health status data of each node in the on-chip optical network;

[0057] Step S102: The fault detection module determines a faulty node of the on-chip optical network based on the health status data;

[0058] Step S103: In response to the failure of the optical network node being unable to recover, the self-healing strategy determination module determines a self-healing strategy corresponding to the on-chip optical network.

[0059] Step S104: the self-healing strategy operation module resets the node links of the on-chip optical network according to the healing strategy.

[0060] Before implementing the method provided by the present disclosure, the system may be initialized. During the system initialization phase, a comprehensive network operation foundation needs to be established.

[0061] Specifically, initialization includes: creating a global routing table to plan routes for data packet transmission and ensure the orderly flow of data within the network; simultaneously completing the initialization of the node health monitoring module to lay a solid foundation for real-time monitoring of node status and timely detection of potential faults. At the same time, the signaling layer is carefully configured to enable efficient data transmission and ensure the smooth interaction of network communication commands.

[0062] During topology design, it is necessary to ensure that the number of nodes is greater than the number of links in order to create a stable and reliable network infrastructure. Mature network topologies such as star, ring, or tree can be selected to meet the network performance requirements in different application scenarios.

[0063] Furthermore, the initial parameters of the off-chip controller can be appropriately set, enabling precise communication with on-chip nodes and achieving internal and external coordinated control. Simultaneously, a coordinate system is constructed to precisely assign unique spatial coordinates to each network node, anchoring the node in the network topology. This provides strong support for efficient subsequent fault location and comprehensive assessment, significantly improving network management and maintenance efficiency.

[0064] In one or more embodiments of the present disclosure, the data monitoring module can monitor the nodes of the on-chip network using an off-chip controller. The monitoring data may include parameters such as temperature, transmission power, node latency, data packet loss rate, and link quality, which can be collected by sensors (such as micro optical sensors, thermocouples, or electronic sensors). Data monitoring can be divided into two modes: full monitoring and incremental monitoring. In addition, real-time analysis of node behavior can be performed to identify possible abnormal fluctuations in order to process data more efficiently.

[0065] In the embodiment of the present disclosure, the data monitoring module may perform monitoring at a preset time according to settings, or perform monitoring after receiving an instruction or signal.

[0066] The above-mentioned fault detection module can identify node faults through a preset fault detection algorithm based on the above-mentioned health status data. The present disclosure does not limit the specific type or content of the above-mentioned fault detection algorithm. When identifying a node fault, the fault type and fault severity of the node can be identified. Among them, the type may include power drop, path interruption or node loss of connection, etc., and the severity of the fault can be evaluated based on whether the faulty node is a critical node (such as a central node or a high-load node) and the network impact that may be caused. In addition, the specific location where the fault occurs and the nature of the fault can also be determined.

[0067] When it is determined that the faulty node is completely failed and cannot be recovered, a self-healing operation is performed on the on-chip optical network.

[0068] It should be noted that, in the technical solution disclosed herein, the type of self-healing solution is determined according to the topology type of the on-chip optical network node.

[0069] In implementing the present disclosure, the applicant discovered that each topology type of on-chip optical network has unique structural characteristics and node distribution. For example, the ring topology is connected in a ring shape, the star topology is centered around a central node, the tree topology supports multi-level distribution with a hierarchical structure, and the mesh and torus topologies are distributed in a mesh-like manner without redundant nodes. Implementing adaptive self-healing strategies based on different topology types can effectively improve self-healing efficiency.

[0070] For a Ring topology, resetting the node links of the on-chip optical network according to the self-healing strategy may include:

[0071] First, the resonant wavelengths of the micro-ring resonators (MRRs) in all optical routers in the on-chip optical network are activated to construct Figure 3 As shown in the clockwise redundant loop. It can be seen that under normal conditions, data packets are transmitted through the counterclockwise link. When the node (0,0) fails, the clockwise link ( Figure 3 first link in ).

[0072] In this step, the Optical Switch Matrix (OSM) can be used to enable bidirectional synchronous transmission, ensuring multipath load balancing and reducing the impact of node failures on loop communication latency. Priority tags can also be used to distinguish between real-time services and disaster recovery data to avoid congestion.

[0073] Afterwards, by judging the proximity scores of other backup nodes in the vicinity of the faulty node, the backup node with the highest proximity score is determined as the target backup node to generate a new link (such as Figure 3 second link shown).

[0074] The proximity score can be obtained based on the distance between the faulty node and the backup node, the signal quality of the link between the nodes of the on-chip optical network, and the historical failure frequency of the backup nodes of the on-chip optical network. In some embodiments of the present disclosure, the mathematical model of the proximity score can be expressed as:

[0075]

[0076] Wherein, α, β and γ are preset weight coefficients. In some embodiments, the values can be 0.5, 0.3 and 0.2. d represents the distance between the faulty node and the backup node. SNR represents the signal quality of the link between the nodes. F history Indicates the historical failure frequency of the standby node.

[0077] For a star topology, the on-chip optical network is pre-configured with a master central node, corresponding shadow central nodes, and peripheral nodes in addition to the master central node. The embodiments of this disclosure primarily propose technical solutions for situations where the master central node in an on-chip optical network with a star topology fails.

[0078] In one or more embodiments of the present disclosure, for a star topology, resetting the node links of the on-chip optical network according to the self-healing strategy may include:

[0079] Build backup links between the shadow central node corresponding to the faulty node and other peripheral nodes in the faulty link.

[0080] To avoid channel conflicts between the shadow central node and the main central node, the wavelength of the microring resonator can be adjusted to seamlessly transmit data packets based on the new wavelength.

[0081] In one or more embodiments of the present disclosure, a dedicated optical channel may be reserved for high-priority services based on service priority.

[0082] by Figure 4 In the illustrated embodiment, the primary central node is (1, 2) and the corresponding shadow central node is (0, 1). When the primary central node fails, the peripheral nodes of the original link, such as (0, 2) and (1, 1), are remapped to the shadow central node to form a backup node.

[0083] For a tree topology, the backup child nodes of the parent node can be pre-stored, and the link status of the backup child nodes (such as bandwidth, delay, and packet loss rate) can be updated in real time and cached locally.

[0084] Resetting the node links of the on-chip optical network according to the self-healing strategy may include:

[0085] The current state and current load of the child node are input into a preset reinforcement learning model to obtain the optimal waiting path. In the embodiment of the present disclosure, the reinforcement learning model can be based on the Proximal Policy Optimization (PPO) algorithm.

[0086] To further enhance the technical effectiveness, the present disclosure also integrates an on-chip optical power monitoring module to monitor the optical signal strength of the reconstructed link in real time. When the optical power loss exceeds a preset threshold, a local rerouting mechanism is triggered, prioritizing redundant idle subnodes within the immediate area to fill the gap and reassessing the optical signal strength of the link.

[0087] like Figure 5 As shown, in one embodiment of the present disclosure, when the parent node (0,1) fails, the child nodes (1,1) and (2,2) are activated. In this embodiment, the optimal alternative is to activate the child node (1,1) and connect it to the child node (0,0). After verifying that the optical power loss is greater than the preset value, the node (3,2) can be selected to fill the gap.

[0088] For Mesh and Torus topologies, you can use predictive traffic engineering and self-healing strategies for elastic topology conversion. Specifically, these strategies include:

[0089] Nodes in Mesh and Torus topologies are embedded in a micro-blockchain module and periodically broadcast their status (such as load, available links, and fault flags). When a node fails, the Raft consensus algorithm can be used to elect a temporary master node near the failed node. After the temporary master node is determined, neighboring nodes submit link resources to the temporary master node.

[0090] To improve the technical effectiveness of the disclosed technical solution, a spatiotemporal graph convolutional network model can be used to predict potential congested areas. The model takes as input a node coordinate matrix, historical traffic data, and real-time link load, and outputs a traffic map that identifies potential congested areas.

[0091] Based on the traffic graph and the improved ant colony algorithm, the optimal path to bypass the fault point can be further obtained. The objective function of the improved ant colony algorithm can be set based on minimizing end-to-end delay and load imbalance. For example, the objective function can be:

[0092]

[0093] Among them, λ represents the balance coefficient, which can be set to 0.6, L represents the total number of links, L j represents the load of the jth link, Indicates the average link load, D i represents the end-to-end delay of the i-th path,

[0094] D max Indicates the maximum allowed delay, which can be set to D max =50μs.

[0095] In order to further improve the technical effect, a topology adjustment strategy based on the fault node density can be implemented in the fuzzy logic controller.

[0096] Specifically, when the node failure density of the on-chip optical network is lower than a preset threshold, the original topology is maintained; when the node failure density is greater than or equal to the preset threshold, the network can be divided into multiple sub-networks, and each sub-network can be converted into a tree topology, and sub-domains can be interconnected through the top parent node optical router.

[0097] That is to say, the input of the fuzzy logic controller is the proportion, location and business type weight of the faulty nodes, and the output is the sub-network topology generated by dynamic adjustment based on the location of the faulty nodes and the business type weight of each node. In computationally intensive scenarios, it prioritizes reducing the number of hops and improving throughput.

[0098] by Figure 5 For example, the coordinates of the failed node are (3, 2). The coordinates of the temporary master node are calculated to be (2, 2). Neighboring nodes (3, 1) and (3, 3) submit available link resources to the temporary master node. Calculation then determines that the potential congestion area is the link load around coordinates (2, 3) with a load greater than 80%. Based on this, the optimal alternative path is ultimately determined to be (2, 2) to (2, 3) to (3, 3).

[0099] In this embodiment, since the fault density is greater than a preset threshold, it is determined through calculation that the network is divided into multiple 2×2 sub-grids (such as coordinates (0,0)-(1,1)).

[0100] After determining the self-healing strategy, the self-healing operation module sends a control signal to the standby node marked during topological self-healing. Upon receiving the signal, the optical router adjusts the resonant wavelength of the microring resonator to open or close the corresponding optical link, ensuring that the standby node completes link takeover in the shortest possible time, achieving seamless handover of data packet communication functions. Furthermore, to avoid optical signal interference or transmission errors caused by parameter adjustments, the system performs multiple status verifications after the adjustment is complete to ensure that the standby node is fully capable of taking over, and then returns an ACK confirmation message to the off-chip controller.

[0101] After receiving the ACK message indicating that the backup node has successfully established a link, the off-chip controller updates the node path information stored in the global routing table to reflect the changes in the topology structure, and runs the shortest path optimization algorithm to recalculate the routes for all nodes in the network to ensure that the data flow can be smoothly transmitted according to the self-healing topology structure. The signaling layer is used to broadcast the routing table information to the relevant nodes. The broadcast adopts a hierarchical design, and prioritizes the synchronization of key nodes (central nodes and high-traffic nodes) to minimize the risk of network interruption.

[0102] After self-healing is completed, the system will verify the current network operation status and evaluate the network recovery by comparing parameters such as the average delay, throughput, bit error rate and link utilization of data packet transmission before and after self-healing. If the ratio of the same coefficients is found to be less than the preset threshold, there is an abnormality in the link. The system will dynamically return to step 4 and re-run the self-healing strategy based on the node feedback. If the ratio is greater than the threshold, there is no abnormality and the system will restart the real-time monitoring module to prepare for changes in the next node failure.

[0103] Therefore, the technical solution disclosed in the present invention adaptively adjusts the self-healing strategy according to the topology structure. Under different topologies, the node self-healing strategy will be targetedly optimized to minimize the data path reconfiguration overhead and link reconstruction time. This strategy effectively reduces the delay caused by the link switching process, while ensuring the efficiency and continuity of the overall data transmission, so as to achieve seamless activation of the replacement node.

[0104] To summarize, in the embodiments of the present disclosure, specifically, in a Ring topology, when an off-chip controller detects a node failure, the self-healing strategy system performs the following operations: adjusts the resonant wavelength of the microring resonator (MRR), constructs a clockwise redundant loop, activates adjacent backup nodes, selects the optimal replacement node based on a comprehensive scoring model of Euclidean distance, link quality, and historical failure rate, uses an optical switch matrix (OSM) to adjust the optical link connection, enables bidirectional path load balancing, and distinguishes real-time services from disaster recovery data through priority labels; in a star topology, when a central node fails, the self-healing strategy system performs the following operations: implements backup switching through a master-shadow dual-center node architecture, the shadow node takes over control within 10μs, adjusts the wavelength of the microring resonator (λ0→λ1) to avoid channel conflicts, and reserves dedicated optical channels for high-priority services; in a tree topology, when a parent node fails, the self-healing strategy system performs the following operations: calls a PPO reinforcement learning model, generates an optimal replacement path based on a child node state snapshot and real-time load, detects the optical signal strength of the reconstructed link in real time through an on-chip integrated optical power monitoring module, and triggers a local rerouting mechanism if the optical power attenuation exceeds a threshold.

[0105] In Mesh and Torus topologies, the self-healing strategy performs the following operations: it deploys a lightweight blockchain framework to periodically broadcast its own status, elects a temporary master node, and uses a spatiotemporal graph convolutional network (ST-GCN) to predict the traffic distribution in the next 10ms when a fault occurs. It then uses an improved ant colony algorithm (ACO) to generate the optimal path around the faulty node, and only updates the local routing table. When the proportion of faulty nodes exceeds a threshold, the network is divided into multiple autonomous subdomains, which are then converted to a tree topology and interconnected through the top parent node optical router. The generated subnetwork topology is dynamically adjusted based on the relevant information of the faulty node through a fuzzy logic controller, and the network structure is optimized according to the fault density and service type to reduce the number of hops.

[0106] The technical solution disclosed in the present invention monitors the health status of network nodes in real time and responds quickly to node failures. It selects a self-healing strategy based on the topology of on-chip optical network nodes, adapts to the self-healing requirements under different topologies, ensures seamless transmission of data packets, and improves the reliability and flexibility of the network.

[0107] The present disclosure is more concise and efficient in determining and handling fault types, reduces the computational burden of the system, and reduces the complexity and overhead of network reconstruction. Especially in high-speed transmission and large-scale network applications, the present disclosure can effectively avoid real-time and scalability issues and enhance the long-term stability and reliability of the network.
