[0002] In today's microservice or distributed architecture systems, efficient interaction and collaboration between services are crucial. In order to achieve smooth calls between services, it is necessary to deploy cluster nodes such as the "service registry" in the system and embed corresponding clients in the service components to establish connections with the cluster.

[0048] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] First of all, before specifically introducing the technical solution of the embodiments of the present application, the technical background based on the embodiments of the present application is introduced.

[0050] Based on this, the present application provides a cluster address list acquisition method, apparatus, computer equipment, medium and product, aiming to solve the above technical problems.

[0051] The cluster address list acquisition method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the service host 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. The server 104 obtains the Internet Protocol addresses of multiple service hosts 102; according to each Internet Protocol address and the pre-acquired minimum threshold of the number of available connections, each service host is processed for communication connection to obtain an available address list; based on the available address list, a periodic keep-alive detection process is performed to obtain a target cluster address list. Among them, the service host 102 runs the physical or virtual host of the service, and the service host can be a physical server or a virtual server instance in a cloud computing environment. These host machines are installed with a service discovery registry or other related service components, which can be accessed and processed for communication connection through the Internet Protocol address. The server 104 can be implemented with an independent server or a server cluster consisting of multiple servers.

[0052] In one embodiment, Figure 2 As shown, a cluster address list acquisition method is provided, and the method is applied to Figure 1 The server in the example is used to illustrate the following steps:

[0053] S201, obtaining Internet Protocol addresses of multiple service hosts.

[0054] The service host refers to a physical server or virtual server instance that runs a specific service. It provides the operating environment and resources for the service and may have key components such as a service discovery registry installed.

[0055] An Internet Protocol address (IP address) is a digital label assigned to each device connected to a computer network for identification and communication in the network. In the embodiment of the present application, the IP address of the service host is key information for locating and connecting to the service host.

[0056] In the embodiment of the present application, the IP addresses of multiple service hosts can be obtained through a pre-configured file or database. For example, when the system starts, a pre-stored service host IP address list is read from a configuration file.

[0057] Another implementation method is to automatically discover the IP address of the service host by means of network scanning. For example, a specific network scanning tool is used to scan within a specific network range to find the host running a specific service and obtain its IP address.

[0058] S202, performing communication connection processing on each service host according to each Internet Protocol address and a pre-acquired minimum threshold of the number of available connections to obtain an available address list.

[0059] The minimum threshold of available connections is a pre-set value used to determine whether the current number of available connections is sufficient. When the number of available connections is less than this threshold, the server will trigger a specific operation to find more available service host addresses.

[0060] The available address list refers to a list of all successfully connected service host addresses obtained after the service host is connected. The service hosts corresponding to the addresses in this list are considered available and can be used for subsequent service calls and communications.

[0061] In an embodiment of the present application, a TCP connection attempt can be used to connect to the IP address of each service host. If the connection is successful, the address is added to the list of available addresses, and relevant information about the connection, such as the connection time, connection status, etc., is recorded. At the same time, a timer is started to regularly perform keep-alive detection on the connection. If the connection fails and the reason for the failure is "connection refused", it is considered that the service discovery registry is not running on the service host, and the address is not added to the list of available addresses.

[0062] Another implementation method: an asynchronous connection method can be used to simultaneously attempt to connect to multiple service host IP addresses. This can improve the efficiency of connection processing and reduce the time to establish a connection. When the connection succeeds or fails, the callback function performs corresponding processing and adds the result to the available address list or excludes the address.

[0063] S203: Perform periodic keep-alive detection processing based on the available address list to obtain a target cluster address list.

[0064] The target cluster address list refers to the final address list obtained after periodic keep-alive detection of the available address list. This list contains the currently available service registration center addresses and is the main basis for the system to call services and communicate.

[0065] In an embodiment of the present application, for each address in the available address list, a specific detection request or heartbeat packet is sent regularly. If a response is received within the specified time, it is considered that the connection is still available and the address continues to be kept in the available address list. If no response is received for multiple consecutive times, the address is deleted from the available address list. At the same time, it is checked whether the number of currently available connections is less than the minimum threshold of the number of available connections. If so, a new round of address detection process is triggered, the IP address of the service host is re-acquired, and connection processing and keep-alive detection are performed.

[0066] Another implementation method: a distributed keep-alive detection mechanism can be used to distribute the keep-alive detection task to multiple nodes for parallel processing. This can improve the efficiency of keep-alive detection and detect connection failures in a timely manner. When a connection failure is found, other nodes are notified through a message passing mechanism so that the available address list is updated in a timely manner and a new round of address detection is triggered.

[0067] The above-mentioned cluster address list acquisition method, device, computer equipment, medium and product obtain the Internet Protocol addresses of multiple service hosts; perform communication connection processing on each service host according to each Internet Protocol address and the pre-acquired minimum threshold of the number of available connections to obtain an available address list; perform periodic keep-alive detection processing based on the available address list to obtain a target cluster address list. The present application performs communication connection processing on the service host according to the Internet Protocol address and the minimum threshold of the number of available connections, and can quickly screen out available addresses, thereby improving the efficiency of address discovery. After obtaining the list of available addresses, periodic keep-alive detection processing is performed, which can monitor the availability of the address in real time, greatly improving the accuracy and reliability of the address list.

[0068] In an exemplary embodiment, based on the above embodiment, see Figure 3 The embodiment of the present application relates to a process of performing communication connection processing on each service host according to each Internet Protocol address and a pre-acquired minimum threshold of the number of available connections to obtain an available address list, including the following steps:

[0069] S301, performing communication connection processing on each service host according to the Internet Protocol address of each service host.

[0070] In the embodiment of the present application, for each service host's IP address, a TCP connection attempt is used to connect. A synchronous connection method can be used to connect to each IP address in turn, and relevant information such as connection time, connection status, etc. is recorded after the connection is successful.

[0071] S302: Determine an available address list according to the minimum threshold of the number of available connections and the candidate protocol addresses.

[0072] The candidate protocol addresses refer to those service host IP addresses that may become available addresses during the communication connection process of the service host.

[0073] In the embodiment of the present application, first, the number of candidate protocol addresses that have successfully established a connection is counted. If this number is greater than or equal to the minimum threshold of the number of available connections, then these successfully connected candidate protocol addresses form an available address list. If the number is less than the minimum threshold of the number of available connections, continue to attempt to connect to other unconnected candidate protocol addresses until the threshold requirement is met or all candidate protocol addresses have been tried.

[0074] The embodiment of the present application can ensure that the addresses in the available address list are all verified available addresses by judging and screening the number of connections, thereby improving the reliability and stability of the system.

[0075] In an exemplary embodiment, based on the above embodiment, see Figure 4 The embodiment of the present application relates to periodic keep-alive detection processing based on an available address list, and the process of obtaining a target cluster address list includes the following steps:

[0076] S401, sending a detection request to each available protocol address in the available address list based on a preset period, and obtaining a detection result of each available protocol address.

[0077] In the embodiment of the present application, a timer can be set to send a lightweight detection request, such as a simple heartbeat packet, to each available protocol address in the available address list according to a preset period. If a response is received within the specified time, the detection result of the address is considered to be available; if no response is received, it is marked as unavailable.

[0078] Another implementation method: a distributed detection method can be used to distribute the detection task to multiple nodes for simultaneous detection. Each node is responsible for detecting a portion of available protocol addresses and aggregating the detection results to the central node for processing. This can improve the detection efficiency and reduce the detection time.

[0079] S402: Update the available address list according to the multiple detection results to obtain a target cluster address list.

[0080] In the embodiment of the present application, the server traverses all detection results, and if the detection result of a certain available protocol address is available, it will continue to be retained in the available address list; if the detection result is unavailable, it will be deleted from the available address list. The updated available address list is the target cluster address list.

[0081] Another implementation method: a buffer area can be set up. For addresses with unavailable detection results, they are first placed in the buffer area and observed for a period of time. If the detection result of the address is restored to be available during the buffer period, it will be added back to the available address list; if it is still unavailable during the buffer period, it will be deleted from the available address list. This can avoid misjudgment due to network fluctuations and other reasons.

[0082] The embodiment of the present application can timely discover the unavailability of addresses through regular keep-alive detection, ensure that the addresses in the target cluster address list are truly available, and improve the reliability of the system.

[0083] In an exemplary embodiment, based on the above embodiment, see Figure 5 The detection results of the embodiment of the present application include survival and inactivation; based on a preset period, a detection request is sent to each available protocol address in the available address list to obtain the detection result of each available protocol address, including the following steps:

[0084] S501: For each available protocol address in the available address list, a detection request is sent to a service host corresponding to the available protocol address.

[0085] In the embodiment of the present application, a network request method, such as an HTTP request or a specific custom protocol request, can be used to send a detection request to a service host. The request can carry some identification information so that the service host can recognize and respond quickly. It is also possible to use an asynchronous method to send detection requests to multiple service hosts at the same time to improve detection efficiency. Asynchronous sending can be achieved using a multithreaded or asynchronous programming framework.

[0086] S502: upon receiving feedback information returned by the service host, determining that the detection result of the service host is alive.

[0087] The feedback information refers to the response of the service host to the detection request, which may be a specific signal, data packet, etc., used to confirm the status of the service host.

[0088] In the embodiment of the present application, after receiving the feedback information returned by the service host, the detection result of the service host is immediately marked as alive, and the time of receiving the feedback and other information are recorded for subsequent analysis and statistics. The feedback information can also be further verified, such as checking the integrity and correctness of the feedback information. Only after the verification is passed, the detection result is determined to be alive.

[0089] S503, when no feedback information is received from the service host, resend the detection request to the service host until the detection request is sent a preset number of times and no feedback information is received, and then determine that the detection result of the service host is inactive.

[0090] In an embodiment of the present application, a counter can be set, and the value of the counter is increased each time feedback information is not received, and a detection request is sent again. When the counter reaches a preset number of times, the detection result of the service host is determined to be inactive, and it is deleted from the list of available addresses. It is also possible to increase the waiting time or adjust the request parameters each time the detection request is resent, such as increasing the timeout time of the request, etc., to increase the possibility of obtaining feedback information. If feedback information is still not received after multiple adjustments, it is determined to be inactive.

[0091] The embodiment of the present application can reduce the possibility of misjudgment and improve the accuracy of judging the availability of the service host by sending multiple detection requests and determining the status of the service host based on the feedback. Timely discovering inactive service hosts and deleting them from the available address list can avoid using unavailable addresses for service calls and improve the reliability of the system.

[0092] In an exemplary embodiment, based on the above embodiments, the embodiments of the present application involve a process of updating an available address list according to multiple detection results to obtain a target cluster address list, including the following steps: retaining the available protocol addresses corresponding to the detection results representing survival in the available address list, and deleting the available protocol addresses corresponding to the detection results representing inactivation in the available address list to obtain a target cluster address list.

[0093] In an embodiment of the present application, the available address list can be traversed, and for each available protocol address, the corresponding detection result can be checked. If the detection result is alive, the address is retained in the available address list; if the detection result is inactive, the address is deleted from the available address list. It is also possible to use a marking method to mark the addresses whose detection results are alive, and then uniformly process the unmarked addresses (i.e., inactive addresses) and delete them from the available address list. This can improve processing efficiency, especially when processing large-scale address lists.

[0094] The embodiment of the present application can ensure that the addresses in the target cluster address list are all available by updating the available address list according to the detection results, retaining only the surviving addresses and deleting the inactive addresses, thereby improving the accuracy of the address list. Using an accurate address list for service calls can avoid service interruptions or errors caused by using unavailable addresses, thereby improving the reliability of the system. As the state of the service host changes, dynamically updating the address list can enable the system to better adapt to changes in resources, reasonably allocate resources, and improve the performance and efficiency of the system.

[0095] In an exemplary embodiment, based on the above embodiment, the method of the embodiment of the present application further includes the following steps:

[0096] When the number of available protocol addresses in the target cluster address list is less than a minimum threshold of the number of available connections, a step of obtaining Internet Protocol addresses of multiple service hosts is performed.

[0097] The embodiment of the present application can set up a monitoring mechanism to regularly check the number of available protocol addresses in the target cluster address list. When it is found that the number is less than the minimum threshold of the number of available connections, the step of obtaining the Internet Protocol addresses of multiple service hosts is immediately triggered. The monitoring can be implemented using a timer or periodic task scheduling. It is also possible to check the number of available protocol addresses in the target cluster address list in real time when the system makes a service call. If it is found that the number is insufficient when making a service call, the process of obtaining a new service host IP address is immediately started to ensure the availability and stability of the service.

[0098] In the embodiment of the present application, when the number of available addresses is insufficient, the step of obtaining new addresses is automatically triggered, so that the system can adaptively respond to changes in address resources, and improve the flexibility and adaptability of the system. By replenishing available addresses in a timely manner, it is ensured that the system has sufficient available connections at all times, thereby improving the availability and stability of the service.

[0099] In an exemplary embodiment, based on the above embodiment, the method of the embodiment of the present application further includes the following steps:

[0100] Step 1: The server obtains the Internet Protocol addresses of multiple service hosts;

[0101] Step 2: Perform communication connection processing on each service host according to the Internet Protocol address of each service host; determine the Internet Protocol address of the successfully connected service host as the candidate protocol address; determine the available address list according to the minimum threshold of the number of available connections and the candidate protocol address;

[0102] Step 3: For each available protocol address in the available address list, send a detection request to the service host corresponding to the available protocol address; if feedback information returned by the service host is received, determine that the detection result of the service host is alive; if no feedback information returned by the service host is received, resend the detection request to the service host until the number of detection request transmissions reaches a preset number and no feedback information is received, determine that the detection result of the service host is inactive;

[0103] Step 4: retain the available protocol address corresponding to the detection result indicating survival in the available address list, and delete the available protocol address corresponding to the detection result indicating inactivation in the available address list, to obtain the target cluster address list;

[0104] Step 5: When the number of available protocol addresses in the target cluster address list is less than the minimum threshold of the number of available connections, the step of obtaining Internet Protocol addresses of multiple service hosts is performed.

[0105] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
