Detailed Implementation

[0015] This application provides a dynamic routing method, apparatus, and electronic device.

[0016] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0017] The dynamic routing method and apparatus provided in this application can be applied to electronic devices, which can be terminals or servers. The server can be a standalone server, a server cluster consisting of multiple servers, or a cloud server capable of cloud computing; the specific implementation is not limited. The terminal can be a device such as a personal computer, a mobile terminal such as a mobile phone or tablet, or a smart wearable device, an in-vehicle terminal, etc.; the specific implementation is not limited.

[0018] The aforementioned dynamic routing methods and devices can be applied to a variety of fields, including but not limited to: environmental monitoring, industrial robot control, real-time acquisition of production line status, remote equipment monitoring, smart grids, smart transportation, smart buildings, etc., and are especially suitable for industrial Internet of Things (IoT) environments with extremely high requirements for communication reliability and real-time performance.

[0019] For example, it can be applied to scenarios such as data center power and environment monitoring, real-time monitoring of cooling and power supply systems, real-time data collection of equipment status in industrial production lines, dynamic routing decision-making on servers in smart transportation, and routing switching and data transmission on sensor devices for fire protection and security in smart buildings.

[0020] The aforementioned dynamic routing method and apparatus, based on multiple logical tunnels for routing and data transmission, achieve intelligent dynamic routing optimization, dynamically adjust data transmission paths, significantly improve the reliability of data transmission and the stability of communication links, and enhance network transmission performance.

[0021] like Figure 1 As shown in the figure, this application embodiment provides a dynamic routing method applied to a server, which may include the following steps: S102: Regularly monitor the status of multiple tunnels and obtain their performance indicators.

[0022] Among them, the aforementioned multiple tunnels include at least two tunnels, such as two, three, or five tunnels, etc., and there is no specific limitation.

[0023] The aforementioned multiple tunnels are logical tunnels obtained by encapsulating the interfaces of multiple networks. Each logical tunnel corresponds to a network, and each network has an interface connecting to the corresponding logical tunnel, which corresponds to an Internet Protocol (IP) address. By constructing a unified logical tunnel above the IP layer through network virtualization encapsulation technology, seamless interoperability across heterogeneous networks can be achieved.

[0024] In this application embodiment, the above-mentioned multiple networks include, but are not limited to, 5G networks, WiFi networks or satellite networks, etc., which are applicable to a wide range of environments, such as field operation environments such as power inspection and geological exploration, or complex industrial environments where multiple protocol devices coexist.

[0025] In this embodiment, network virtualization encapsulation technology can be used to construct logical tunnels, such as using Virtual Extensible Local Area Network (VxLAN) as the tunnel encapsulation technology. VxLAN is a UDP-based Layer 3 network overlay technology that can build virtual Layer 2 networks on existing IP networks. VxLAN has a large identifier space, a 24-bit Virtual Network Identifier (VNI), is decoupled from the physical network, and has a high degree of standardization. It can realize a unified logical transmission channel across heterogeneous access networks, support wireless data transmission across subnets and wide area networks, and adapt to the needs of large-scale IoT.

[0026] For example, see Figure 2 Two VxLAN tunnels are established, one for the 5G network and one for the WiFi network. The 5G network has a VNI of 100 and is bound to the interface of its corresponding VxLAN tunnel; this tunnel is used to carry high-performance, low-latency services. The WiFi network has a VNI of 200 and is bound to the interface of its corresponding VxLAN tunnel; this tunnel is used to provide stable backup or carry low-speed services.

[0027] In this embodiment of the application, step S102 may include: Periodically send probe messages to the interface of each of the multiple tunnels; Receive the response messages returned by the interface of each tunnel; The performance metrics of multiple tunnels are obtained based on the received response messages.

[0028] The period for sending probe messages can be preset, such as once every 500ms, and the specific value is not limited.

[0029] In this embodiment of the application, the performance indicators of the tunnel may include a variety of factors, such as at least one of the following: round-trip time (RTT), packet loss rate, bandwidth, and reachability.

[0030] In this embodiment of the application, the above-mentioned probe message can be: Internet Control Message Protocol (ICMP) Echo request message or User Datagram Protocol (UDP) probe packet, etc., or a custom message format such as a message containing a timestamp and / or sequence number, etc., which is not limited in specific terms.

[0031] In this embodiment, the server can statistically analyze the performance metrics of each tunnel based on the received response messages, and can also record whether the tunnel status is up to standard or not. For example, if the RTT of a VxLAN-5G tunnel is <50ms and the packet loss rate is <1%, the tunnel status is recorded as up to standard, representing a "good" status. If the RTT of a VxLAN-WiFi tunnel is >100ms or the packet loss rate is >5%, the tunnel status is recorded as not up to standard, representing a "degraded" status.

[0032] The mechanism for parallel probing of multiple tunnels in this application embodiment enables parallel performance data collection on multiple heterogeneous links, ensuring that the server can continuously monitor the availability and quality differences of different links, providing a complete decision-making basis for subsequent route optimization. Probing is conducted via targeted sending and receiving through the tunnel virtual interface, enabling independent evaluation of tunnel layer performance and avoiding interference from fluctuations in the underlying links.

[0033] S104: Determine a routing decision based on the performance indicators of multiple tunnels and a preset strategy. The routing decision includes information about the transmission path, which is a tunnel selected from multiple tunnels.

[0034] In this embodiment of the application, the step S104 above, which determines the routing decision based on the performance indicators of multiple tunnels and a preset strategy, may include: The aforementioned multiple tunnels include at least the first tunnel and the second tunnel, with the first tunnel having a higher priority than the second tunnel. If the performance indicators of both the first tunnel and the second tunnel meet the standards, the first tunnel will be selected as the transmission path. If the performance indicators of the first tunnel continue to fail to meet the standards while the performance indicators of the second tunnel meet the standards, it is determined to switch from the first tunnel to the second tunnel as the transmission path. Once the performance indicators of the first tunnel have recovered and met the standards, it will be determined to switch from the second tunnel to the first tunnel as the transmission path.

[0035] The aforementioned routing decision-making process enables adaptive and intelligent path selection under multi-link conditions, ensuring that the transmission path is always in an optimal state. For example, it can guarantee that when a high-priority tunnel is continuously unsatisfactory, it can switch to a low-priority tunnel that is in good condition, and when a high-priority tunnel recovers and stably meets the requirements, it can switch back to a high-priority tunnel, realizing dynamic routing and intelligent tunnel switching.

[0036] In this embodiment of the application, performance index failure means that the performance index is higher than the first threshold, and performance index compliance means that the performance index is lower than the second threshold, wherein the first threshold is greater than the second threshold.

[0037] For example, the first threshold is 100ms, and RTT>100ms means that RTT is not up to standard. The second threshold is 50ms, and RTT<50ms means that RTT is up to standard. The first threshold of 100ms is greater than the second threshold of 50ms.

[0038] For example, the first threshold is 5%, and a packet loss rate > 5% means the packet loss rate is not up to standard. The second threshold is 2%, and a packet loss rate < 2% means the packet loss rate meets the standard.

[0039] In this embodiment of the application, the performance indicators of the first tunnel continuously failing to meet the standards include: the performance indicators of the first tunnel continuously failing to meet the standards for a first duration, or the number of times the performance indicators of the first tunnel fail to meet the standards reaches the first time.

[0040] The first duration can be preset, such as 50ms, 1s, or 2s, and the specific value is not limited. For example, if the performance indicators of the first tunnel fail to meet the standards for 1 second, the system will switch from the first tunnel to the second tunnel.

[0041] The number of times for the first attempt can be preset, such as 3, 5, or 10 times, with no specific limit on the value. For example, if the performance indicators of the first tunnel fail to meet the standards for three consecutive times, the system will switch from the first tunnel to the second tunnel.

[0042] For example, if the performance metrics of both the VxLAN-5G tunnel and the VxLAN-WiFi tunnel meet the standards, the VxLAN-5G tunnel will be used first. If the RTT of the VxLAN-5G tunnel is consistently >100ms and / or the packet loss rate is consistently >5% (for a certain duration or number of occurrences), and the performance metrics of the VxLAN-WiFi tunnel still meet the standards (e.g., RTT <80ms), then switch to the VxLAN-WiFi tunnel. When the RTT of the VxLAN-5G tunnel recovers to <50ms and remains stable (for a certain duration or number of occurrences), then switch back to the VxLAN-5G tunnel.

[0043] This application embodiment determines whether the performance indicators are continuously substandard by the duration or number of times, and the conditions for switching out of the tunnel are stricter than the conditions for switching into the tunnel (i.e., the first threshold is greater than the second threshold). This can filter short-term fluctuations, avoid frequent switching caused by instantaneous network jitter, improve anti-jitter capability, and improve system stability.

[0044] See Figure 3 In a scenario where both VxLAN-5G and VxLAN-WiFi tunnels are established, the process by which the server obtains the performance metrics of these two tunnels can include: the server periodically sends ICMP Echorequest messages to the interface of each tunnel and receives response messages returned by each interface. The server calculates the RTT and packet loss rate of the received response messages. If the RTT of the VxLAN-5G tunnel is <50ms and / or the packet loss rate is <2%, the performance metrics of the VxLAN-5G tunnel meet the standards, indicating that the 5G network signal is good, and the VxLAN-5G tunnel is selected as the transmission path, with data transmitted through the VxLAN-5G tunnel. If the RTT of the VxLAN-5G tunnel is >100ms and / or the packet loss rate is >5%, the performance metrics of the VxLAN-5G tunnel do not meet the standards, indicating that the 5G network signal is deteriorating, and the VxLAN-WiFi tunnel is selected as the transmission path, automatically switching to the VxLAN-WiFi tunnel, with data transmitted through the VxLAN-WiFi tunnel.

[0045] Additionally, when all tunnel performance indicators fail to meet the standards, i.e., when all tunnels are unavailable, an alarm can be triggered, or a reconnection attempt can be made.

[0046] S106: Update the local routing rules based on the above routing decisions.

[0047] The server has stored routing rules locally. These rules can be in the form of a routing table, which includes various information about the transmission path, such as VNI, interface, and the IP address corresponding to the interface.

[0048] For example, if the routing decision determines to switch from the first tunnel to the second tunnel, the server can modify the interface of the first tunnel in the routing rules to the interface of the second tunnel, thereby realizing the route update.

[0049] S108: The routing decision is sent to the terminal through the above transmission path. The routing decision is used by the terminal for routing and data transmission.

[0050] The server can encapsulate routing decisions into control messages and send them to the terminal through currently available tunnels, such as by sending routing decisions to the terminal via Transmission Control Protocol (TCP) messages.

[0051] In this embodiment, the server can also periodically send heartbeat messages or status synchronization messages to the terminal to dynamically synchronize routing decisions and tunnel status information. For example, the server sends a status synchronization message or heartbeat message to the terminal every 500ms to ensure that the terminal's status is consistent with the server's. Thus, the terminal can automatically update its local routing rules based on the latest routing decisions, ensuring that data is transmitted along the optimal path without manual intervention.

[0052] In addition, each time the server and terminal synchronize routing decisions, they can also perform two-way authentication, such as authentication based on the national cryptographic SM2 / 4 algorithm, which can effectively avoid illegal attacks and improve security.

[0053] The method provided in this application embodiment periodically monitors the status of multiple tunnels to obtain their performance indicators. These multiple tunnels are logical tunnels obtained by encapsulating the interfaces of multiple networks. A routing decision is determined based on the performance indicators of the multiple tunnels and a preset strategy. This routing decision includes transmission path information, which is a tunnel selected from the multiple tunnels. The routing decision is sent to the terminal via the transmission path so that the terminal can perform routing and data transmission. By performing routing and data transmission based on multiple logical tunnels, intelligent dynamic routing optimization is achieved, dynamically adjusting the data transmission path, significantly improving the reliability of data transmission and the stability of the communication link. This enhances network transmission performance and effectively meets the stringent communication requirements of high-real-time and high-reliability application scenarios such as industrial automation, remote monitoring, and the Industrial Internet of Things.

[0054] Moreover, the aforementioned method intelligently and dynamically coordinates the heterogeneous bandwidth resources of various networks, avoiding excessive congestion or idleness of some link resources, fully leveraging the maximum efficiency of network resources, improving overall network resource utilization, and enhancing overall network performance. This significantly improves communication assurance capabilities in high-reliability scenarios such as industrial monitoring, data centers, and smart cities. Furthermore, it achieves seamless interconnection between cross-protocol devices, improving compatibility and collaborative capabilities among various device types, reducing deployment complexity and costs, and providing a scalable solution capable of flexibly addressing diverse future business needs.

[0055] like Figure 4 As shown in the figure, this application embodiment provides another dynamic routing method, applied to a terminal, which may include the following steps: S402: Receive routing decisions sent by the server, which include information about the transmission path.

[0056] The transmission path is a tunnel selected from multiple tunnels, which are multiple logical tunnels obtained by encapsulating the interfaces of multiple networks respectively.

[0057] For example, the server pre-establishes two VxLAN tunnels, one for the 5G network and the other for the WiFi network. Based on the status of the two tunnels, the server determines a routing decision and sends it to the terminal. This routing decision includes the VNI and interface information of the VxLAN tunnel corresponding to the WiFi network.

[0058] S404: Update local routing rules based on routing decisions.

[0059] The terminal has stored routing rules locally. These routing rules can be in the form of a routing table, which includes various information about the current transmission path, i.e., the tunnel, such as the VNI, the interface, and the IP address corresponding to the interface.

[0060] For example, if the transmission path in the above routing decision is a VxLAN tunnel of a WiFi network, but the terminal is currently using a VxLAN tunnel of a 5G network, then after receiving the routing decision, the terminal immediately updates its local routing rules, modifying the VxLAN tunnel information of the 5G network to the VxLAN tunnel information of the WiFi network, such as VNI and interface, thereby realizing the route update.

[0061] For example, a terminal can update its routing table using the ip rule or ip route command.

[0062] S406: Use the transmission path for data transmission.

[0063] See Figure 5 The dynamic routing method described above may include the following steps: The server executes a routing decision algorithm to obtain a routing decision, which is then sent to the terminal via a control message. The terminal receives and parses the control message to obtain the routing decision, and then updates its local routing table. When data arrives, the terminal forwards the data flow according to the updated routing table.

[0064] In this embodiment, the terminal can run a built-in routing proxy service to receive and parse control messages sent by the server to obtain routing decisions. Based on the obtained routing decisions, if the server has selected a new transmission path, the terminal immediately updates its local routing rules, thereby enabling it to use the new transmission path for data transmission and directing service traffic to the updated tunnel.

[0065] The above process can complete the switching within tens of milliseconds, ensuring that the service flow is not interrupted during the link switching process and meeting the requirements of data transmission for real-time performance and reliability.

[0066] It should be noted that the server periodically monitors the status of each tunnel. Once a transmission path change occurs again, the server switches to the new tunnel and immediately synchronizes the routing decision with the terminal. Upon receiving the new routing decision, the terminal also immediately switches to the new tunnel, thus maintaining consistency in the status of both the server and the terminal. Even in the event of link failure or performance degradation, it can achieve fast (≤50ms) seamless switching, significantly improving the stability and robustness of communication.

[0067] The method provided in this application embodiment receives routing decisions sent by a server, which include transmission path information. It updates local routing rules according to the routing decisions, uses the transmission path for data transmission, and dynamically adjusts the data transmission path based on the server's routing decisions. This ensures that the data stream is transmitted according to the latest transmission path in the routing decisions, which not only achieves intelligent dynamic routing optimization, but also significantly improves the reliability of data transmission and the stability of communication links, as well as the efficiency of data transmission, thereby enhancing the transmission performance of the network.

[0068] This application provides a dynamic routing system, including: The server is used to periodically monitor the status of multiple tunnels and obtain their performance metrics. The multiple tunnels are logical tunnels obtained by encapsulating the interfaces of multiple networks. The server determines routing decisions based on the performance metrics of the multiple tunnels and preset policies. The routing decisions include information about the transmission path, which is a tunnel selected from the multiple tunnels. The routing decisions are then sent to the terminal through the transmission path. The terminal is used to receive routing decisions sent by the server, update local routing rules according to the routing decisions, and use the transmission path for data transmission.

[0069] See Figure 6 The process of the above system executing the dynamic routing method can be as follows: The server periodically uses ICMP probe messages to monitor the status of the VxLAN-5G tunnel and the VxLAN-WiFi tunnel. Based on the probe results returned by the two tunnels, the server compares the tunnel performance metrics such as RTT or packet loss rate. The server dynamically selects the optimal tunnel and synchronizes the routing decision to the terminal. Upon receiving the decision, the terminal updates its local routing table. When a data stream arrives, it sends the data stream according to the updated preferred tunnel. The server sends a synchronization heartbeat to the terminal every 500ms to synchronize the routing status of both parties. The server monitors whether any tunnel can resume transmission. If the server detects that a tunnel has resumed transmission, it can switch to the resumed tunnel and notify the terminal that it can switch to the resumed tunnel for data transmission.

[0070] The system provided in this application embodiment periodically monitors the status of multiple tunnels and obtains their performance indicators. These multiple tunnels are logical tunnels obtained by encapsulating interfaces of multiple networks. Routing decisions are determined based on the performance indicators of the multiple tunnels and a preset strategy. The routing decision includes transmission path information, where the transmission path is a tunnel selected from the multiple tunnels. The routing decision is sent to the terminal via the transmission path. The terminal receives the routing decision from the server, updates its local routing rules based on the routing decision, and uses the transmission path for data transmission. This enables intelligent dynamic routing optimization, dynamically adjusting the data transmission path, significantly improving the reliability of data transmission and the stability of the communication link, enhancing network transmission performance, and effectively meeting the stringent communication requirements of high-real-time and high-reliability application scenarios such as industrial automation, remote monitoring, and the Industrial Internet of Things.

[0071] Furthermore, based on a reliable transmission mechanism with multi-tunnel redundancy, it can automatically switch to another tunnel if one tunnel fails, improving communication reliability and effectively enhancing the network's resilience against single points of failure, meeting the stringent reliability requirements of industrial applications. Through real-time link status detection and intelligent routing decision algorithms, it can cope with network congestion and state changes, improving network transmission performance, reducing latency, and increasing throughput. It ensures that in the event of tunnel performance degradation or interruption, it can rapidly switch to the optimal backup path within milliseconds, guaranteeing the continuity and stability of data transmission.

[0072] Based on the same idea as the dynamic routing method provided in the embodiments of this application, the embodiments of this application also provide a dynamic routing device, such as... Figure 7 As shown, when applied to a server, the device may include: The monitoring module 701 is used to periodically monitor the status of multiple tunnels and obtain the performance indicators of multiple tunnels.

Once the performance indicators of the first tunnel have recovered and met the standards, it will be determined to switch from the second tunnel to the first tunnel as the transmission path.

[0078] In this embodiment of the application, the above-mentioned performance index failure means that the performance index is higher than the first threshold, and the performance index compliance means that the performance index is lower than the second threshold, wherein the first threshold is greater than the second threshold.

[0079] In this embodiment of the application, the performance indicators of the first tunnel continuously failing to meet the standards include: the performance indicators of the first tunnel continuously failing to meet the standards for a first duration, or the number of times the performance indicators of the first tunnel fail to meet the standards reaches the first time.
