Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a TCP connection management method, device, electronic equipment, storage medium and program product. Background Art

[0002] The Transmission Control Protocol (TCP) is a reliable, byte-stream-based communication protocol for multi-device interconnection. Its main function is to establish a stable data transmission connection between two computers, ensuring the sequential transmission of data packets, data integrity, and error detection and recovery. When network communication uses the TCP / IP protocol, a TCP connection needs to be established between the client and the server before reading and writing operations, and the TCP connection is released after the reading and writing operations are completed.

[0003] TCP connections require a timeout heartbeat mechanism to detect whether the connection is still active. The heartbeat mechanism is to confirm that the connection is still valid and active by sending signals (usually empty messages or specific probe packets) at regular intervals. The timeout mechanism means that if no heartbeat signal or any data is received within a specified time, the system will consider the connection to be invalid. However, the existing TCP connection management method uses the same timeout heartbeat mechanism to manage different operation events, making it difficult to quickly respond to sudden changes in network conditions or changes in load in a dynamic network environment, resulting in low management efficiency. Summary of the invention

[0037] Figure 3 It is a structural schematic diagram of an electronic device of the present invention. DETAILED DESCRIPTION

[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] Figure 1 A flowchart of a TCP connection management method 100 according to an embodiment of the present disclosure is shown. The TCP connection management method can be executed by a TCP connection management system. Specifically, the method 100 includes:

[0040] S101. According to the event content of a preset event, a timing strategy matching the preset event is set, wherein the preset event includes any one of the following: no data read operation on the Transmission Control Protocol TCP connection channel between the client and the server, no data write operation on the TCP connection channel, no data read operation and no data write operation on the TCP connection channel;

[0041] In this step, an event handler in the TCP connection management system can be defined to handle three types of events: no data read operation on the TCP connection channel between the client and the server, no data write operation on the TCP connection channel between the client and the server, and neither data read operation nor data write operation on the TCP channel between the client and the server.

[0042] The above events can be used to detect the status and activity of the TCP connection channel between the client and the server.

[0043] Different operations (data reading, data writing, or simultaneous data reading and writing) have different characteristics and resource requirements. For example, data reading may be a more passive wait, while data writing is usually more active and frequent. The same timeout heartbeat strategy cannot effectively meet these different requirements, which may cause some connections to fail to detect the inactive state in time or misjudge the active state.

[0044] Therefore, in this step, different preset events are set with different timers, that is, different preset times are set with different timing strategies. According to the time interval set to match the preset event, the TCP connection management system will periodically check the TCP connection channel to detect whether a preset event has occurred on the TCP connection channel.

[0045] For example:

[0046] 1. Data read operations may sometimes be in a waiting state, that is, the client is waiting for data from the server. You can set a longer timeout because read operations may not be frequent. If a connection does not receive a data packet for a long time, you may need to send a heartbeat packet to detect the connection activity to ensure that both parties can still communicate.

[0047] 2. Data writing is usually an active operation, meaning that the client is constantly sending data to the server. A shorter timeout can be set because data writing is usually more frequent and stable. If there is a long period of inactivity during the writing process, it may indicate a problem that needs to be quickly detected and handled.

[0048] 3. Bidirectional communication with simultaneous data reading and writing means that the connection should always remain active, sending and receiving data at the same time. It is necessary to comprehensively consider the above two situations and flexibly adjust the timeout parameters to adapt to the dynamic changes of read and write synchronization.

[0049] S102, according to the timing strategy matching the preset event, polling and monitoring whether the preset event occurs on the TCP connection channel;

[0050] In some embodiments, the polling and monitoring whether the preset event occurs on the TCP connection channel according to the timing strategy matching the preset event includes:

[0051] Obtaining the timestamp of the most recent data reading operation and / or data writing operation on the TCP connection channel according to the listening time interval matching the preset event;

[0052] Calculate the difference between the timestamp of the most recent data read operation and / or data write operation on the TCP connection channel and the current timestamp;

[0053] The difference is compared with the idle time threshold matching the preset event to determine whether the preset event occurs on the TCP connection channel.

[0054] In the above embodiment, taking the data writing operation on the TCP connection channel as an example, the data reading operation on the TCP connection channel is checked according to the set listening time interval (such as listening once every 5 seconds), and then the difference between the timestamp of the most recent data reading operation on the TCP connection channel and the current timestamp is calculated. When the difference exceeds the preset space-time threshold, it means that no data writing operation has been performed on the TCP connection channel for a long time.

[0055] This embodiment can handle various possible situations in network communications more accurately and efficiently by matching different timing strategies to different preset events.

[0056] S103. According to the monitoring situation, the TCP connection channel is managed based on a key value composed of the identification information of the client and the connection information of the TCP connection channel, wherein the identification information of the client includes any one of the following: an Internet Protocol IP address of the client or a port number of the client, and the connection information of the TCP connection channel includes at least one of the following: the identification information of the TCP connection channel, the connection state of the TCP connection channel, the most recent activity timestamp of the TCP connection channel, and the data transmission volume of the TCP connection channel.

[0057] In this step, the connection manager in the TCP connection management system can manage the TCP connection channel through a key-value consisting of the identification information of the client and the connection information of the TCP connection channel. The identification information of the client can be the Internet Protocol (IP) address of the client or the port number of the client, and the connection information of the TCP connection channel can include at least one of the following: the identification information of the TCP connection channel, the connection state of the TCP connection channel, the most recent activity timestamp of the TCP connection channel, and the data transmission volume of the TCP connection channel.

[0058] Continuing with the example of monitoring data write operations on the TCP connection channel, if the TCP connection channel performs a data write operation within the preset idle time interval, the corresponding value is found according to the client's identification information (key), and the connection status of the TCP connection channel, the timestamp of the most recent data write operation, and the amount of data written are updated.

[0059] If the TCP connection channel has not performed any data writing operations for a long time, the corresponding value can be found based on the client's identification information (key) and deleted.

[0060] In some embodiments, before setting a timing strategy matching the preset event according to the event content of the preset event, the method further includes:

[0061] Get the TCP connection request sent by the client;

[0062] Based on the TCP connection request, establishing a TCP connection channel between the client and the server;

[0063] After the TCP connection channel is established, a key-value pair consisting of the identification information of the client and the connection information of the TCP connection channel is stored in a database.

[0064] In the above embodiment, when a TCP connection channel is established between the client and the server, a key-value pair consisting of the identification information of the client and the connection information of the TCP connection channel can be stored in the database. This makes it convenient to record the detailed information of each TCP connection. By analyzing the stored connection information, the system can better dynamically allocate resources, thereby improving the management efficiency of the TCP connection.

[0065] In some embodiments, managing the TCP connection channel based on a key value consisting of identification information of the TCP connection channel and connection information of the TCP connection channel according to the monitoring situation includes:

[0066] When the preset event occurs on the TCP connection channel, disconnect the TCP connection channel;

[0067] After disconnecting the TCP connection channel, the key-value pair consisting of the identification information of the client and the connection information of the TCP connection channel is deleted from the database.

[0068] In the above embodiment, taking the data writing operation on the TCP connection channel as an example, if the TCP connection channel has not been used for a long time, it can be considered that the TCP connection channel may no longer be needed. In order to release the occupied network and system resources, the system will actively disconnect the TCP connection channel that has no writing activity for a long time. After the connection is disconnected, the record related to this connection (the key-value pair consisting of the client identification information and the connection information) can be deleted from the database.

[0069] This embodiment actively disconnects TCP connections that have been inactive for a long time, which helps to free up limited resources of the server, such as memory, ports, and bandwidth, and improves the system's ability to handle new and active requests. It also ensures data consistency and accuracy by regularly cleaning useless entries in the database, and prevents subsequent business logic from making erroneous decisions based on outdated or invalid data.

[0070] In some embodiments, after storing the key-value pair consisting of the identification information of the client and the connection information of the TCP connection channel in the database, the method further includes:

[0071] Get the resource capacity of the server;

[0072] Calculate the maximum number of TCP connection channels that the server can connect to based on the resource capacity;

[0073] Determine a threshold value of the number of TCP connection channels to which the client can connect based on the maximum number of TCP connection channels and usage information of the client;

[0074] Querying the number of key-value pairs corresponding to the client in a database according to the identification information of the client;

[0075] When the number of key-value pairs corresponding to the client is greater than the TCP connection channel number threshold, the client is restricted from establishing a new TCP connection channel with the server.

[0076] In the above embodiment, the resource capacity of the server is obtained by identifying and evaluating the hardware and software resources of the server (such as the central processing unit (CPU), memory, bandwidth, etc.) to understand how many concurrent TCP connections it can support. Based on the above resource capacity, the maximum number of stable TCP connections that the server can handle is calculated. According to the calculated maximum number of connections, combined with the usage information of each client (which may include its resource requirements, priority, etc.), a specific upper limit on the number of connections is set for each client, namely the "TCP connection channel number threshold". Using the client's identification information, the corresponding connection information is searched in the database to determine the number of connections currently established by the client (through existing key-value pairs). If the number of connections established by the client exceeds the threshold set for it, the client is prevented from establishing a new connection to avoid overloading server resources.

[0077] In this embodiment, limiting the number of TCP connections can prevent the server from receiving too many requests and being overloaded, thereby maintaining system performance and service quality, and ensuring that all clients are treated fairly when competing for limited resources, especially in a multi-user environment, to prevent a single user from occupying too many resources.

[0078] According to an embodiment of the present disclosure, a TCP connection management method includes setting a timing strategy that matches a preset event according to the event content of the preset event, wherein the preset event includes any one of the following: no data read operation on the Transmission Control Protocol TCP connection channel between the client and the server, no data write operation on the TCP connection channel, and no data read operation and no data write operation on the TCP connection channel; according to the timing strategy that matches the preset event, polling and monitoring whether the preset event occurs on the TCP connection channel; according to the monitoring situation, managing the TCP connection channel based on a key value composed of the identification information of the client and the connection information of the TCP connection channel, wherein the identification information of the client includes any one of the following: the Internet Protocol IP address of the client or the port number of the client, and the connection information of the TCP connection channel includes at least one of the following: the identification information of the TCP connection channel, the connection status of the TCP connection channel, the most recent activity timestamp of the TCP connection channel, and the data transmission volume of the TCP connection channel. In the method, different timing strategies are set for different preset events, so that the connection status of the TCP connection channel can be accurately identified and detected, and the TCP connection channel is managed based on the connection status of the TCP connection channel through a key value pair composed of the identification information of the client and the connection information of the TCP connection channel, which can conveniently record the detailed information of each TCP connection channel. By analyzing the stored connection information, the system can better dynamically allocate resources, thereby improving the management efficiency of the TCP connection.
