[0002] Currently, the monitoring of a cluster network is usually based on an OpenStack cloud platform and mainly monitors the heartbeat between a server and a computing node. In general, since the default heartbeat network is only deployed on a management network, if the management network is disconnected, a user cannot implement operations such as starting and stopping a virtual machine on a physical host of the management network, which leads to low accuracy of monitoring data. SUMMARY

[0003] Therefore, the present application provides a node high-availability implementation method and system, a computer device and a storage medium to solve the problem of low accuracy of monitoring of a node.

[0004] In a first aspect, the present application provides a node high-availability implementation method applied to a node high-availability implementation system, and the method comprises the following steps.

[0005] A plurality of network monitoring services and a high-availability service are respectively deployed for each node in a cluster; the plurality of network monitoring services are used to monitor the network status of different networks in the node; the high-availability service is configured with a high-availability configuration file, and the high-availability configuration file is used to represent the correspondence between the network status of each network in the node and a high-availability action;

[0006] Based on the network monitoring service, the current network status of each network in the node is obtained;

[0007] Based on the high-availability configuration file and the current network status of each network in the node, a target high-availability action corresponding to the node is determined and executed.

[0008] In this way, the current network status of different networks in the node can be monitored through the plurality of network monitoring services, and the target high-availability action corresponding to the node can be determined and executed according to the current network status of each network in the node through the high-availability service, so that the network monitoring of the node and the execution of the high-availability action are separated, the various networks of the node can be monitored at the same time, the monitoring accuracy of the node is improved, and since the corresponding high-availability action is executed through the separate high-availability service, a response can still be generated when a problem occurs in the network of the node, thereby improving the reliability of the node and the cluster network.

[0009] In an optional implementation, the networks in the node include a management network, a service network and a storage network, the network monitoring service includes a management network monitoring service, a service network monitoring service and a storage network monitoring service; based on the network monitoring service, the current network state of each network in the node is obtained, including:

[0010] The management network of the node is monitored based on the management network monitoring service to obtain the current management network state of the node;

[0011] The service network of the node is monitored based on the service network monitoring service to obtain the current service network state of the node;

[0012] The storage network of the node is monitored based on the storage network monitoring service to obtain the current storage network state of the node.

[0016] The multiplexed network of the first node is monitored based on the network monitoring service corresponding to any network in the multiplexed network to obtain the current multiplexed network state of the first node; the multiplexed network is a network corresponding to a physical network device implementing at least two networks in the first node.

[0017] In this way, when the node has a multiplexed network, the network states of the multiplexed network are combined into one network state, so that corresponding high-availability actions can also be planned and executed for network multiplexing, thereby improving the network reliability of the node and the cluster.

[0028] Mount the high-availability configuration file in the fault handling service to start the high-availability service.

[0029] In this way, the network monitoring service and the fault handling service are deployed in the node in the form of an image file, and when it is necessary to deploy the network monitoring service or the fault handling service in the node, the deployment can be completed directly by configuring the image file, thereby realizing flexible configuration and deployment of the network monitoring service and the fault handling service; meanwhile, the high-availability service is started by mounting the high-availability configuration file in the fault handling service, thereby making the configuration and implementation of the high-availability service more flexible.

[0030] In an optional implementation, based on the high-availability configuration file and the current network state of each network in the node, a target high-availability action corresponding to the node is determined and executed, including:

[0057] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0058] Currently, the monitoring of the cluster network is usually based on the OpenStack cloud platform and mainly monitors the heartbeat between the server and the computing node. In general, since the default heartbeat network is only deployed on the management network, if the management network is disconnected, the user cannot implement the operations such as starting and closing the virtual machine on the physical host with the disconnected management network, resulting in low accuracy of the monitoring data. Moreover, since the heartbeat network is only deployed on the management network, the situation when the storage network and the service network fail cannot be considered, resulting in low reliability of the network monitoring of the node. In addition, since the on-site network environment is usually complex and the network reuse situation is relatively high, the matrix of the high-availability service configured in the related technology is usually fixed and cannot be modified, which cannot achieve setting the high-availability action according to the specific network planning, resulting in that the high-availability service cannot make accurate host evacuation actions.

[0059] Based on this, the embodiments of the present application provide an implementation method of node high availability, applied to an implementation system of node high availability, and the method comprises the following steps: deploying a plurality of network monitoring services and a high-availability service for each node in the cluster respectively; the plurality of network monitoring services are used for monitoring the network states of different networks in the node; the high-availability service is configured with a high-availability configuration file, and the high-availability configuration file is used to represent the corresponding relationship between the network states of each network in the node and the high-availability action; based on the network monitoring service, the current network states of each network in the node are obtained; based on the high-availability configuration file and the current network states of each network in the node, the target high-availability action corresponding to the node is determined and executed. In this way, the current network states of different networks in the node can be monitored through the plurality of network monitoring services, and the corresponding target high-availability action can be determined and executed according to the current network states of each network in the node through the high-availability service, so as to separate the network monitoring of the node and the execution of the high-availability action, which can monitor various networks of the node at the same time, improve the monitoring accuracy of the node, and since the corresponding high-availability action is executed through the separate high-availability service, the response can still be generated when the network of the node has a problem, thereby improving the reliability of the node and the cluster network.

[0060] According to the embodiment of the present application, a node high-availability implementation method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.

[0061] In the embodiment, a node high-availability implementation method is provided, which can be used in a node high-availability implementation system. Figure 1 The flowchart of the node high-availability implementation method according to the embodiment of the present application is shown in FIG. 1, which includes the following steps: Figure 1

[0062] In step S101, a plurality of network monitoring services and high-availability services are respectively deployed for each node in the cluster.

[0063] In the embodiment of the present application, the plurality of network monitoring services are used to monitor the network states of different networks in the node. The high-availability service is configured with a high-availability configuration file, which is used to represent the correspondence between the network states of each network in the node and the high-availability actions. Through the high-availability configuration file, the high-availability action to be performed by the current network state of the node can be determined.

[0064] In an optional implementation, the network detection service can be implemented by a consul service. The consul service is a service discovery and configuration management center service. The consul service is built-in with a service registration and discovery framework, a distributed consistency protocol implementation, a health check, a Key / Value storage, a multi-data center solution, etc. It can provide any number of health checks, which can be associated with a given service or a local node.

[0065] In an optional implementation, corresponding to different networks in the node, a corresponding network monitoring service is respectively deployed to monitor the network state of the corresponding network, and the network state is reported to the high-availability service to determine the high-availability action to be performed at present through the high-availability service.

[0066] ​In an optional embodiment, the high-availability service can be implemented based on a fault handling service masakari, the high-availability service is started by mounting a high-availability configuration file in the fault handling service masakari, automatic failover and recovery are realized by monitoring the compute nodes and virtual machine instances, so as to improve the stability and reliability of the cloud infrastructure. The masakari can continuously monitor the states of the compute nodes and virtual machine instances, when a fault or abnormal condition is found, an automatic fault handling process is triggered, the affected virtual machine instances are automatically migrated to other healthy compute nodes, so as to reduce the service interruption time, and the administrator can also be sent a notification and alarm information, so that the administrator can take timely measures to ensure the normal operation of the cloud environment.

[0067] In an optional embodiment, the deployment of the network monitoring service and the high-availability service is based on an OpenStack cloud platform. The OpenStack cloud platform is an open source cloud computing platform, which can provide various cloud computing services to build a cloud infrastructure. In the related art, the high-availability service is usually implemented by deploying a host high-availability solution of masakari on the OpenStack cloud platform, using masakari to build a high-availability service, monitoring the network states of the nodes in the cluster and performing high-availability actions, and the high-availability actions configured in the high-availability service are fixed and cannot be modified. In the embodiment of the present application, a high-availability configuration file is configured in the high-availability service built by masakari, and the high-availability configuration file itself can be modified, so that the high-availability service can be flexibly configured.

[0068] In step S102, based on the network monitoring service, the current network states of the networks in the node are obtained.

[0069] In the embodiment of the present application, the health of each network in the node is detected in real time based on the network monitoring service corresponding to each network configured in the node, so that the current network states of the networks in the node are obtained, and the network monitoring service reports the monitored current network states to the high-availability service, and the high-availability service determines the high-availability actions to be performed at present.

[0070] In step S103, based on the high-availability configuration file and the current network states of the networks in the node, the target high-availability actions corresponding to the node are determined and performed.

[0071] In the embodiment of the present application, the high-availability service obtains the current network states of the corresponding networks reported by the network monitoring services, and compares and matches the network states with the high-availability actions configured in the high-availability configuration file, determines the target high-availability actions corresponding to the node under the current network states, and performs the target high-availability actions, so as to realize the high-availability function and ensure the reliability of the node and the cluster.

[0072] In an optional implementation, the high-availability actions configured in the high-availability configuration file can be configured based on a highly available policy. The highly available policy is a policy for ensuring that a computing system or service remains available and continues to provide services in the face of hardware failures, software problems, or other unexpected situations, which can include the following policies: taking over work with redundant components to ensure service continuity, which requires setting up redundant components to achieve redundant deployment; migrating workloads from a failed node to a healthy backup node to achieve seamless failover; load balancing by distributing traffic to multiple servers or nodes to avoid single-node overload and improve overall system availability and performance; regularly backing up critical data and replicating data across multiple locations or storage media to prevent data loss and support rapid data recovery; resuming business and continuing operation based on a pre-set failure recovery plan when a failure occurs; setting up an alarm mechanism to alert failure conditions.

[0073] In an optional implementation, the high-availability actions in the high-availability configuration file can be set according to the specific configuration of the node, that is, the high-availability configuration files of different node configurations can be different, so that the deployment of high-availability services for different nodes can be customized, improving the flexibility of high-availability deployment. At the same time, when initially deploying the network monitoring service and the high-availability service on the nodes in the cluster, a general high-availability configuration file can be used to deploy the high-availability service of the nodes in the cluster, so as to quickly complete the deployment of the network monitoring service and the high-availability service.

[0074] In an optional implementation, after the high-availability service is deployed on the node, the high-availability configuration file configured in the high-availability service can also be updated, that is, even after the high-availability service is deployed on the node, it can be updated after deployment, thereby achieving high flexibility and dynamic configurability of the high-availability service. Specifically, in response to high-availability modification information of a target node, high-availability configuration information is obtained; based on the high-availability configuration information, the high-availability configuration file is updated; and the updated high-availability configuration file is mounted in the failure handling service of the target node to update the high-availability service of the target node. The target node is a node that needs to update the high-availability service. After responding to the high-availability modification information, the updated high-availability configuration information of the target node is obtained, and the high-availability configuration file is regenerated according to the updated high-availability configuration information, thereby updating the high-availability configuration file. At the same time, the updated high-availability configuration file is mounted in the failure handling service of the target node, and the update of the high-availability service of the target node is completed, thereby improving the flexibility of the high-availability service.

[0075] The method for implementing node high availability provided in the embodiments of the present application comprises the following steps of: respectively deploying multiple network monitoring services and a high availability service for each node in a cluster; the multiple network monitoring services are used for monitoring network states of different networks in the node; the high availability service is configured with a high availability configuration file, and the high availability configuration file is used for representing a corresponding relationship between network states of each network in the node and high availability actions; based on the network monitoring services, current network states of each network in the node are obtained; based on the high availability configuration file and the current network states of each network in the node, a target high availability action corresponding to the node is determined and executed. In this way, the current network states of different networks in the node can be monitored through the multiple network monitoring services, and the corresponding target high availability action can be determined and executed according to the current network states of each network in the node through the high availability service, so that the network monitoring of the node and the execution of the high availability action are separated, the various networks of the node can be monitored at the same time, the monitoring accuracy of the node is improved, and since the corresponding high availability action is executed through the separate high availability service, a response can still be generated when a network problem of the node occurs, so that the reliability of the node and the cluster network is improved.

[0076] In the embodiments of the present application, a method for implementing node high availability is provided, which can be used for a system for implementing node high availability, Figure 2 is a flowchart of another method for implementing node high availability according to the embodiments of the present application, as shown in the figure, the flowchart comprises the following steps: Figure 2

[0077] Step S201, respectively deploying multiple network monitoring services and a high availability service for each node in a cluster. For details, please refer to step S101 of the embodiment shown in Figure 1 The embodiment will not be described here again.

[0078] Step S202, based on the network monitoring services, obtaining current network states of each network in the node.

[0079] In the embodiments of the present application, the networks in the node can include a management network, a service network and a storage network, and correspondingly, the network monitoring services include a management network monitoring service, a service network monitoring service and a storage network monitoring service.

[0080] Then, the above step S202 can comprise the following steps:

[0081] Step S2021, based on the management network monitoring service, performing network monitoring on the management network of the node to obtain a current management network state of the node.

[0082] In the embodiments of the present application, the management network monitoring service performs network monitoring on the management network of the node to obtain a current management network state of the node, and reports the current management network state to the high availability service.

[0083] ​In step S2022, the service network monitoring service performs network monitoring on the service network of the node to obtain a current service network state of the node.

[0084] In the embodiment, the service network monitoring service performs network monitoring on the service network of the node to obtain a current service network state of the node, and reports the current service network state to the high-availability service.

[0085] In step S2023, the storage network monitoring service performs network monitoring on the storage network of the node to obtain a current storage network state of the node.

[0086] In the embodiment, the storage network monitoring service performs network monitoring on the service network of the node to obtain a current service network state of the node, and reports the current service network state to the high-availability service.

[0087] Thus, by the above method, the management network monitoring service, the service network monitoring service, and the storage network monitoring service respectively monitor the network states of the management network, the service network, and the storage network of the node, and the network states of different networks in the node are monitored.

[0088] In an optional embodiment, if there is a first node in the cluster, and at least two networks of the first node are implemented based on the same physical network device, that is, the networks of the first node are multiplexed, the step S202 has the following two cases:

[0089] In the first case, for a non-multiplexed network, that is, a network corresponding to a physical network device implementing one network in the first node, the non-multiplexed network is monitored based on a network monitoring service corresponding to the non-multiplexed network to obtain a current non-multiplexed network state of the first node.

[0090] In the second case, for a multiplexed network, that is, a network corresponding to a physical network device implementing at least two networks in the first node, the multiplexed network is monitored based on a network monitoring service corresponding to any network in the multiplexed network to obtain a current multiplexed network state of the first node.

[0091] Thus, by the above method, when the node has a multiplexed network, the network states of the multiplexed network are combined into one network state, and thus the high-availability actions can also be planned and executed according to the network multiplexing, thereby improving the network reliability of the node and the cluster.

[0092] In an optional embodiment, if the node has a multiplexed network, the high-availability configuration file can be modified accordingly to adapt to the high-availability service related to the multiplexed network.

[0093] In an optional embodiment, if there is a second node in the cluster and the second node adopts a fiber channel connection storage network, then the network state of the storage network is no longer monitored by the service monitoring the storage network in the second node, but is monitored by the port state of the fiber port. Specifically, the port state of the fiber port of the second node is detected to determine the port state of the fiber port, and based on the port state, the current storage network state of the second node is determined. Thus, when the storage network adopts a fiber channel to access the node, the network state of the storage network is determined by detecting the port state of the fiber port, thereby improving the comprehensiveness and applicability of the network monitoring of the node.

[0094] In step S203, based on the high-availability configuration file and the current network state of each network in the node, a target high-availability action corresponding to the node is determined and executed. For details, please refer to Figure 1 The step S103 of the embodiment shown will not be described here.

[0095] In this embodiment, a node high-availability implementation method is provided, which can be used in a node high-availability implementation system, Figure 3 is a flowchart of another node high-availability implementation method according to an embodiment of the application, as shown in the figure, the flow includes the following steps: Figure 3

[0096] Step S301, respectively deploying multiple network monitoring services and high-availability services for each node in the cluster.

[0097] Specifically, step S301 can include the following steps:

[0098] Step S3011, constructing an image file of the network monitoring service and the fault handling service, and pushing the image file of the network monitoring service and the fault handling service to the image repository corresponding to the running environment of the cluster.

[0099] In the embodiment of the application, an image file of the network monitoring service consul service and the fault handling service masakari service is constructed, and the image file of the network monitoring service consul service and the fault handling service masakari service is pushed to the image repository corresponding to the running environment of the cluster, that is, the image repository corresponding to the OpenStack environment. By doing image processing, the image file is pushed to the image repository, and when the network monitoring service and the fault handling service are deployed in each node in the cluster, the image file in the image repository can be directly called to complete the deployment of the network monitoring service and the fault handling service.

[0100] ​In an optional embodiment, when deploying the network monitoring service and the fault handling service to each node in the cluster, the nodes to which the network monitoring service and the fault handling service need to be deployed can be listed through a node inventory, and the deployment of the network monitoring service and the fault handling service can be completed based on the node inventory. In an optional embodiment, an inventory file can be used as the node inventory, the nodes to which the related services need to be deployed can be configured by listing the names, IPs, addresses or configurations of the nodes in the inventory file, and then the image file in the image repository can be pushed to the nodes included in the inventory file according to the related information in the inventory file, so as to complete the deployment of the network monitoring service and the fault handling service on the nodes.

[0101] Figure 4 is a schematic diagram of deploying an image file in the implementation method of node high availability according to an embodiment of the present application, and the following will be further described in combination with Figure 4 The deployment of the image file in the embodiment of the present application to deploy the network monitoring service and the fault handling service in the node will be further described. As shown in Figure 4 , centos8.2 is selected as a container base image, the consul executable file of the network monitoring service is integrated and installed in the base image, and the consul image is constructed; the masakari related code and the analysis algorithm of the high availability action matrix are integrated in the base image, and the masakari image is constructed; the consul image and the masakari image are pushed to the image repository corresponding to the OpenStack environment. Then the nodes to which the services need to be deployed are specified in the inventory file, so that the consul image and the masakari image in the image repository are pushed to the corresponding nodes, so as to deploy the network monitoring service and the fault handling service in the nodes. Optionally, when the network monitoring service and the fault handling service are deployed in the nodes, a switch for starting the high availability service can be added in the global control file, so that the high availability service can be started or stopped through the switch.

[0102] Figure 5 is a schematic diagram of starting the network monitoring service and the high availability service in the implementation method of node high availability according to an embodiment of the present application, as shown in Figure 5 , after the image files of the network monitoring service and the fault handling service are deployed to the nodes, the network monitoring service and the high availability service need to be started in the nodes, and the specific steps are shown in steps S3012 to S3016.

[0103] Step S3012, the network configuration information of each network in the node is detected.

[0104] In the embodiment of the present application, the network in the node includes a management network, a service network and a storage network. The network configuration information of the management network, the service network and the storage network is detected respectively to determine whether the configuration of the management network, the service network and the storage network in each node has been completed. If the network configuration information of each network is detected, it indicates that the configuration of each network in the node has been completed and the node has been connected to each network. If the network configuration information of each network is not detected or only the network configuration information of some networks is detected, it indicates that the configuration of each network in the node has not been completed and the network is not completely connected. At this time, a prompt is fed back to prompt the user that the management network, the service network and the storage network have not been configured.

[0105] In step S3013, if the network configuration information is detected, the node configuration information of each node is acquired, and the node configuration file corresponding to each node is generated based on the node configuration information.

[0106] In the embodiment of the present application, if the network configuration information is detected, the node can be further configured to start the network monitoring service and the high-availability service. First, the node configuration information of each node is acquired, and the node configuration file corresponding to each node is generated based on the node configuration information, thereby facilitating the subsequent start of the network monitoring service and the high-availability service. The node configuration information includes the configuration information of the network card, the network and the host of the node, and the node configuration file can be a configmap file.

[0107] In step S3014, the node configuration file is mounted, and the management network monitoring service, the service network monitoring service and the storage network monitoring service in the network monitoring service are started.

[0108] In the embodiment of the present application, the management network monitoring service is used to monitor the network state of the management network of the node, the service network monitoring service is used to monitor the network state of the service network of the node, and the storage network monitoring service is used to monitor the network state of the storage network of the node. The node configuration file is mounted, and then the consul-manager pod service is started respectively to start the management network monitoring service to monitor the network state of the management network, the consul-storage pod service is started to start the storage network monitoring service to monitor the network state of the storage network, and the consul-tenant pod service is started to start the service network monitoring service to monitor the network state of the service network.

[0109] In step S3015, the high-availability configuration information is acquired, and the high-availability configuration file is generated based on the high-availability configuration information.

[0110] In this embodiment of the invention, high availability configuration information is obtained, and a high availability configuration file is generated based on the high availability configuration information. The high availability configuration file can be a configmap file. Optionally, the high availability configuration information can be obtained by parsing the obtained high availability action matrix configuration file.

[0111] Step S3016: Mount the high availability configuration file in the fault handling service to start the high availability service.

[0112] In this embodiment of the invention, a high availability configuration file is mounted in the fault handling service masakari to start the high availability service. Therefore, by using the above method, network monitoring and fault handling services are deployed on nodes in the form of image files. When it is necessary to deploy network monitoring or fault handling services on a node, deployment can be completed directly by configuring the image file, thus enabling flexible configuration and deployment of network monitoring and fault handling services. Simultaneously, by starting the high availability service by mounting a high availability configuration file in the fault handling service, the configuration and implementation of the high availability service become more flexible.

[0113] Step S302: Based on the network monitoring service, obtain the current network status of each network in the node. For details, please refer to [link to relevant documentation]. Figure 1 Step S102 of the illustrated embodiment will not be described again here.

[0114] Step S303: Based on the high availability configuration file and the current network status of each network in the node, determine and execute the target high availability action corresponding to the node. For details, please refer to [link to relevant documentation]. Figure 1 Step S103 of the illustrated embodiment will not be described again here.

[0115] This embodiment provides a method for implementing node high availability, which can be used in systems that implement node high availability. Figure 6 This is a flowchart of a method for implementing high availability of another node according to an embodiment of the present invention, such as... Figure 6 As shown, the process includes the following steps:

[0116] Step S601 involves deploying multiple network monitoring and high availability services on each node in the cluster. For details, please refer to [link to relevant documentation]. Figure 1 Step S101 of the illustrated embodiment will not be described again here.

[0117] Step S602: Based on the network monitoring service, obtain the current network status of each network in the node. For details, please refer to [link to relevant documentation]. Figure 1 Step S102 of the illustrated embodiment will not be described again here.

[0118] Step S603, determining and executing a target high-availability action corresponding to the node based on the high-availability configuration file and the current network status of each network in the node.

[0119] Specifically, step S603 can include the following steps:

[0120] Step S6031, determining the high-availability action corresponding to the current network status of each network based on matching the current network status of each network in the node with the high-availability configuration file.

[0121] In the embodiments of the present application, Figure 7 is a schematic diagram of a high-availability configuration file in a method for implementing high availability of a node according to an embodiment of the present application, as shown in Figure 7 The high-availability configuration file can include the network status of each network, and the network status of each network constitutes a set of network status, and a set of network status corresponds to a high-availability action. As shown in Figure 7 The management interface corresponds to the network status of the management network, the tenant interface corresponds to the network status of the service network, the storage interface corresponds to the network status of the storage network, and the actions correspond to the high-availability action; up and down in the high-availability configuration file represent different network status, wherein up represents normal network status, and down represents abnormal network status; recovery and report represent different high-availability actions, Figure 7 which is only an example, and in actual applications, the configuration can be performed according to the needs of the cluster or the node.

[0122] In an optional embodiment, the high-availability configuration file can only configure the situation that needs to generate a response, that is, for some situations that do not need to perform a high-availability action, the corresponding network status can not be configured in the high-availability configuration file, so as to reduce the amount of data contained in the high-availability configuration file and improve the efficiency of determining the high-availability action. Optionally, as shown in Figure 7 , for some situations that do not need to perform a high-availability action, the action configuration is consistent with the action configuration when the management network, the service network and the storage network are in the normal state (up) in Figure 7 , that is, the network status is listed in the high-availability configuration file, but the corresponding action is not performed, so as to ensure the integrity of the configuration of the network status in the high-availability configuration file and improve the reliability of the high-availability configuration file.

[0123] Step S6032, determining the high-availability action corresponding to the current network status of each network as a target high-availability action, and executing the target high-availability action.

[0124] In the embodiment, the high-availability action corresponding to the current network state of each network in the high-availability configuration file is determined as a target high-availability action, and the target high-availability action is executed. In this way, according to the configuration of the high-availability action in the high-availability configuration file, the high-availability action corresponding to the current network state is determined and executed.

[0125] In the embodiment, a node high-availability implementation system is also provided, which is used to implement the above-described embodiments and preferred embodiments, and will not be described again. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function.
