[0020] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are some of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the application.

[0021] The terms "first", "second", and the like in the specification and claims of the application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the application can be implemented in an order other than those illustrated or described herein. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0022] The network fault intelligent routing method, the network fault intelligent routing device, the electronic device, and the computer readable storage medium provided by the embodiments of the application will be described in detail below with reference to the drawings, specific embodiments, and application scenarios.

[0023] Referring to Figure 1 , a step flowchart of a network fault intelligent routing method provided by an embodiment of the application is shown, and the method can specifically include the following steps: Step 101, generating all network topology sets corresponding to a customer according to service configuration information of the customer obtained from an SD-WAN controller; the network topology sets include a current network topology and a standby network topology being used by the customer; The SD-WAN controller is based on the customer's service configuration information, a set of network topologies, which includes not only the current network topology currently in use, but also one or more backup network topologies available. The operation and management platform visually presents this set of topologies to the user. Through linkage with the device location positioning method, the location of the topology node, such as the intelligent access gateway, can be accurately marked on the physical map, and the current active topology path and the backup path can be dynamically displayed. When the system detects that the current network topology has failed or deteriorated in performance, the system can automatically or after confirmation by the administrator, quickly switch the traffic to the optimal backup network topology to ensure business continuity.

[0024] In an embodiment provided by the present application, the service configuration information can include the service configuration parameters obtained by the SD-WAN controller from the SD-WAN service order system after the customer opens the service, resource pool VPC information, the customer associated POP information, customer intelligent gateway information, VPC and POP connection link, different resource pool POP connection link, intelligent gateway and POP connection link, etc.

[0025] First, the SD-WAN controller obtains the service configuration parameters from the SD-WAN service order system after the customer opens the service. Then the SD-WAN controller device issues the initialization parameters to the intelligent gateway device of the customer, and the intelligent gateway device selects and allocates the SD-WAN network element POP device according to the issued service configuration parameters to establish network connection, so that the customer's local network can communicate with the VPC network of each resource pool.

[0026] After establishing the service channel, the intelligent decision system obtains the service configuration parameters of the customer from the SD-WAN controller, generates all network topology graph sets corresponding to the user ID of the customer, including the topology graph currently used by the customer and all backup topology graphs for future intelligent routing, saves all network topology graphs in the intelligent decision system, and all topology graphs include all node data and connection link data of the customer.

[0027] Step 102, receiving real-time data corresponding to the monitoring indicators of the current network topology returned by the network data acquisition system; The intelligent decision system synchronizes the network topology set (current topology and backup topology) generated by it to the network data acquisition system, and clearly needs to monitor the target object. The monitoring and alarm system predefines the performance indicators and alarm thresholds that need to be monitored for different types of topology links according to the business, and sends them to the network data acquisition system. The network data acquisition system actively detects and measures the network according to the received topology and indicators, collects real-time performance data, and feeds back to the intelligent decision system.

[0028] In an embodiment, the step 102 can include the following sub-steps: Sub-step S11, sending the network topology set to a network data collection system; The intelligent decision system encapsulates the generated network topology set. The encapsulated data structure not only includes graphical information of the topology, but also includes: unique device identifiers of all nodes in the topology, such as intelligent access gateways, management IP addresses; unique identifiers of all links in the topology, link types, node information; and type identification of each topology, such as current primary or backup. After encapsulation, the intelligent decision system actively pushes or responds to requests to the network data collection system through a predefined, reliable API interface, and pushes or responds to requests to the network data collection system through a predefined, reliable API interface.

[0029] This step aims to inform the network data collection system what needs to be collected. By receiving the topology set, the data collection system can accurately know which nodes and path performance between which links need to be collected, thereby avoiding resource waste caused by full collection and realizing precise and on-demand data collection.

[0030] Sub-step S12, receiving real-time data corresponding to the monitoring indicators of the network topology of the network data collection query, the monitoring indicators of the network topology being configured by a monitoring and alarm system.

[0031] The monitoring and alarm system pre-defines a complete set of monitoring indicators according to the operation and maintenance strategy, such as link delay, jitter, packet loss rate, bandwidth utilization, device CPU / memory utilization, etc. The set of indicators and their alarm thresholds are synchronized to the network data collection system. After receiving the topology set from the intelligent decision system, the network data collection system initiates a data query based on the set of indicators defined by the monitoring and alarm system. It collects real-time data of the above indicators from specific network devices identified in the topology set through a southbound interface protocol. The network data collection system feeds back the collected real-time data to the intelligent decision system.

[0032] The monitoring and alarm system is used for the definition of indicators and the management of alarm rules. The network data collection system is used for processing high-performance and high-concurrency data collection tasks. The intelligent decision system does not need to care about the complex details of the underlying data collection, but only needs to obtain the required high-quality real-time data through a standard interface, so as to focus on its core data analysis, path quality evaluation and switching decision functions, and improve the professionalism, scalability and stability of the entire system.

[0033] Step 103, determining whether the network quality of the current network topology fluctuates according to real-time data corresponding to monitoring indicators of the current network topology; After the intelligent decision system obtains the network topology set and its corresponding real-time monitoring data, the health status of the current network topology is then evaluated. That is, through quantitative analysis, it is intelligently determined whether the quality of the current network topology has undergone significant fluctuations, thereby providing a decision basis for potential topology switching.

[0034] In an embodiment, the step 103 can include the following sub-steps: Sub-step S21, obtaining an array composed of real-time data corresponding to the monitoring indicators of the current network topology within a period of time according to the real-time data corresponding to the monitoring indicators of the current network topology; In some embodiments provided by the present application, the intelligent decision system continuously receives real-time data streams from the network data acquisition system, first pre-processes these data, and can also record the values of a group of core monitoring indicators once every 30 seconds according to a preset sampling period. Then, according to the specific monitoring indicator data of all sampling points, a data array is formed in a set evaluation time window, for example, in a unit of past 5 minutes. The monitoring indicators are multiple, and generally include but are not limited to: time delay, jitter, packet loss rate, bandwidth utilization rate, ingress traffic, egress traffic, etc. Multiple arrays can be generated for the current network topology, such as a time delay array = [d1, d2,..., dn], a packet loss rate array = [l1, l2,..., ln], etc.

[0035] Sub-step S22, obtaining the network quality score of the current network topology according to the array of the monitoring indicators of the current network topology within a period of time; In some embodiments provided by the present application, since the dimensions and value ranges of different monitoring indicators are different (for example, the unit of time delay is millisecond, and the unit of packet loss rate is percentage), the intelligent decision system first processes the data in each array, and the intelligent decision system starts to record the network quality indicator data arrays with time stamp as the horizontal coordinate within a certain time period T.

[0036] The network quality score value is calculated according to the following method:

[0037]

[0038] : the data corresponding to the monitoring indicator i, : the standard value corresponding to the monitoring indicator i, : the weight ratio value (0-1.0) corresponding to the monitoring indicator i. The weight is adjusted by the user of the monitoring system according to his / her own experience, for example, the storage class service values disk / io monitoring, and the computing service values cpu.

[0039] In substep S23, if the network quality score of the current network topology is lower than a preset threshold, it is determined that the network quality of the current network topology fluctuates.

[0040] In some embodiments provided by the application, the intelligent decision system compares the calculated real-time network quality score with a preset quality threshold. The threshold is defined by the operation and maintenance strategy and can be flexibly adjusted according to different customers or different service level agreements of different service levels. If the network quality score value Score is lower than the preset threshold, the system determines that the network quality of the current network topology fluctuates, which means that the current primary topology can not meet the service demand, and the system will trigger the subsequent standby topology evaluation and switching process.

[0041] The embodiment of the application changes the perception of network quality from the experience judgment of operation and maintenance personnel to the objective quantitative score based on data, eliminating subjectivity. By comprehensively integrating multiple key indicators and performing weighted calculation, the real experience of the network can be more comprehensively and accurately reflected, and misjudgment due to temporary changes of a single indicator can be avoided. Through periodic continuous evaluation, the system can identify the fluctuation trend before the network quality decreases to affect the key business, laying a foundation for predictive maintenance and active switching, and greatly improving the intelligent level and service guarantee capability of the SD-WAN network.

[0042] In step 104, if the network quality of the current network topology fluctuates, a target network topology is determined from the standby network topologies; In an embodiment, the step 104 can include the following substeps: In substep S31, if the network quality of the current network topology fluctuates, the network quality score of the standby network topology is determined, and a network quality score set of the standby topology is obtained. In some embodiments provided by the application, for each standby network topology, the intelligent decision system also obtains real-time monitoring data of the links and nodes from the network data acquisition system. Based on a data array in an evaluation time window, a comprehensive network quality score is calculated using the same weighted scoring algorithm. The calculated scores of all standby network topologies are associated with the identification information of the topologies to form a network quality score set of the standby topology.

[0043] The data structure of the set can be represented as: {standby topology ID-1: score-1, standby topology ID-2: score-2,...}. The set dynamically reflects the real-time quality level of each standby topology at the current time.

[0044] In substep S32, according to the network quality score set of the standby topology, the standby network topology with the highest score is selected as the target network topology.

[0045] In some embodiments provided by the present application, the intelligent decision system ranks and compares all network quality scores in the score set. The system selects one backup network topology with the highest network quality score and marks it as the target network topology. This selection strategy ensures that when the primary topology fluctuates or fails, the traffic will be switched to the backup path with the best quality and the best guarantee for business, thereby realizing smooth transition of service quality instead of simply switching to any available backup link.

[0046] Step 105, according to the target network topology, determining the corresponding backup SD-WAN POP network element device; In some embodiments provided by the present application, the intelligent decision system reads the data of the selected target network topology. These data define the detailed structure of the topology, including: the complete path of the data flow from the source site to the destination site, all network nodes that must be passed through in the path, especially the SD-WAN POP points as intermediate access points or switching points, and the logical or physical interface identifiers used by the traffic to enter and leave each node.

[0047] Then the intelligent decision system can identify the POP points and match the network element devices, extract the identifiers of all SD-WAN POP points acting as intermediate nodes such as POP-ID from the path sequence according to the parsed topology structure, and then query the local or synchronized network resource repository database from the controller. The database can store detailed information of all POP points in the network, including the mapping relationship between each POP point identifier and one or more physical network element devices (such as PE routers, gateway devices) under it. By matching the POP point identifiers in the topology with the resource repository database, the system determines one or more specific and physical SD-WAN POP network element devices for each required POP point and obtains its management address or device ID.

[0048] By unified compilation and delivery of configurations by the SD-WAN controller, it is ensured that even in an emergency switching scenario, the business policies on all network element devices are highly accurate and completely consistent, completely avoiding errors and ambiguities that may be caused by manual device-by-device configuration.

[0049] Step 106, controlling the SD-WAN controller to deliver the customer's business configuration information to the corresponding backup SD-WAN POP network element device, so that the backup SD-WAN POP network element device recreates the customer's business network configuration.

[0050] In some embodiments provided by the application, the intelligent decision system issues instructions for reconfiguring the network to the SD-WAN controller. After receiving the instructions from the intelligent decision system, the SD-WAN controller retrieves complete customer service configuration information corresponding to the target network topology from the service configuration database according to the target network topology. The SD-WAN controller then accurately issues specific configuration commands to each standby SD-WAN POP network element device specified in the instruction list. Each standby SD-WAN POP network element device receives and loads the configuration issued by the controller.

[0051] The device recreates routing table entries, access control lists, traffic shaping queues, and the like related to the customer service according to the new configuration rules. The customer's service traffic can be guided by the intelligent access gateway to the newly created network path based on the standby POP point.

[0052] The embodiment of the application discloses a network fault intelligent routing method, which is applied to an intelligent decision system, generates all network topology sets corresponding to customer service configuration information obtained from an SD-WAN controller, includes a current network topology and a standby network topology used by the customer, receives real-time data corresponding to monitoring indicators of the current network topology returned by a network data acquisition system, determines whether the network quality of the current network topology fluctuates according to the real-time data, determines a target network topology from the standby network topology if the fluctuation occurs, determines corresponding standby SD-WAN POP network element devices, controls the SD-WAN controller to issue the customer service configuration information to the corresponding standby SD-WAN POP network element devices, and makes the standby SD-WAN POP network element devices re-create the customer service network configuration. In the case that network fluctuation occurs in the customer enterprise networking link, intelligent decision is made based on real-time link network data, so that the customer enterprise networking can have high network quality.

[0053] Referring to Figure 2 , another network fault intelligent routing method provided by the embodiment of the application is shown, and the method can specifically include: Step 1: The SD-WAN service order system issues service configuration to the SD-WAN controller device after the customer opens the service. After the customer registers the serial number (SN) of the intelligent gateway and activates the service, the SD-WAN controller generates customer service initialization parameters including a unique user ID in the whole network. The SD-WAN controller device issues the service configuration to the intelligent gateway device of the customer. Referring to Figure 3 ​, shows a routing device diagram of the network fault intelligent routing method provided by the embodiment of the application. The intelligent gateway device selects and allocates the SD-WAN network element POP device according to the configuration information issued. At this time, the service data channel is formally built, and the customer local network can perform network communication with the VPC networks of various resource pools.

[0054] In the embodiment of the application, the SDN network controller can be selected as the SD-WAN controller device, the POP network element device can be implemented by using a Linux server with multiple backup high-performance network cards, and the intelligent gateway can be implemented by using an embedded hardware device in cooperation with a Linux operating system. The SD-WAN controller, the POP network element device, and the intelligent gateway select public networks to establish IPSEC tunnels for secure network communication. The selection of specific hardware and systems is not limited in the application.

[0055] Step 2: After the service channel is established, the intelligent decision system obtains the configuration of the service of the customer from the SD-WAN controller , generates all network topology graphs corresponding to the customer (user ID ) according to the configuration information of the customer, the resource pool VPC information, the POP information associated with the customer, the intelligent gateway information of the customer, the VPC and POP connection link, the POP connection link of different resource pools, and the intelligent gateway and POP connection link, saves all network topology graphs in the intelligent decision system, and all topology graphs include all node data and connection link data of the customer.

[0056]

[0057] In this step, the SD-WAN controller accesses the SDN controller API in the cloud to obtain the VPC information in the cloud (including the network IP, network segment, route, VLAN, and the like of the customer in the cloud), obtains the POP related information (including the intelligent gateway connection IP, customer route, forwarding route, VLAN, and the like) through the POP network element device, and obtains the customer side network access information through the intelligent gateway. All data including the network information of each node and the connection between each node and other nodes are stored in the database in the form of a graph data structure.

[0058] Step 3: The intelligent decision system sends the network topology graph information set to the network data collection system to start the data collection task of the customer. The network data collection system splits all topology objects in the topology information into monitoring objects that can be recognized by the monitoring system, and the single network topology object​​​ all network links and server information to the monitoring alarm system.

[0059]

[0060]

[0061] In an embodiment provided by the present application, a Linux server and a database can be selected and used as a network data collection system, a monitoring system such as ZABBIX / Prometheus is used as a bottom monitoring alarm system, the network data collection system splits a customer business topology graph into monitoring objects that can be recognized by the bottom monitoring alarm system, and the configuration of monitoring indicators and the query of data are completed through the API of the bottom monitoring alarm system.

[0062] Step 4: The monitoring alarm system configures monitoring indicators according to all network links information and server information , the monitoring indicators include but are not limited to the following set: packet loss rate, time delay, jitter, ingress traffic, egress traffic, etc. The monitoring indicators generate a monitoring indicator ID array through a user ID and a monitoring object, and return the array to the network data collection system.

[0063]

[0064] In an embodiment provided by the present application, the network data collection system calls the monitoring system API to create network quality indicators such as packet loss rate, time delay, jitter, ingress traffic, egress traffic, etc., and generates a globally unique monitoring indicator ID through a user ID and the link ID , calls the network data collection system API to return and all monitoring indicator ID sets corresponding to the ID to the network collection system.

[0065] Step 5: Repeat step 4 to configure monitoring indicators for all topology objects in the set .

[0066] This embodiment iterates through the set , and repeats step 4 to achieve the same effect.

[0067] Step 6: The network data collection system queries real-time data of all monitoring indicators corresponding to the monitoring indicator ID according to the topology graph corresponding to the current customer . The data is then sent to the intelligent decision-making system. The intelligent decision-making system begins recording data over a certain period of time. An array of network quality metrics data with timestamps as the horizontal axis.

[0068] Calculate the network quality score using the following method:

[0069]

[0070] : The data corresponding to monitoring metric i This is the standard value corresponding to the monitoring indicator i. The weight ratio (0-1.0) corresponding to the monitoring indicator i.

[0071] In this embodiment, a network data acquisition system is used according to... The system retrieves all corresponding network monitoring metrics sets and iterates through these sets to query the corresponding implementation monitoring data for each metric. The intelligent decision-making system uses the aforementioned algorithm formula to... The period serves as a moving window, and scores are calculated for all data within that period.

[0072] Step 7: If scoring is done within this period All values ​​were below the expected standard. The intelligent decision-making system determined that the user's network quality was fluctuating and initiated intelligent routing.

[0075] In one embodiment of the present invention, the SD-WAN controller issues new service configurations and configures relevant routes on the replacement target POP.

[0076] Step 9: After the backup link is established, suspend the previous service topology. , the new standby topology switching is formally enabled, and the intelligent routing is completed.

[0077] In an embodiment provided by the application, the SD-WAN controller starts test traffic after the standby network configuration takes effect, and deletes the previous old network configuration after the test passes.
