Description

Technical Field

[0001] This application relates to the field of data transmission technology, and more specifically, to a data processing method, apparatus, and processor. Background Technology

[0002] Transmission Control Protocol (TCP) is a connection-oriented, reliable, byte-stream-based transport layer communication protocol. TCP is designed to adapt to layered protocol hierarchies that support multiple network applications. Pairs of processes on host computers connected to different but interconnected computer networks rely on TCP for reliable communication services. For example, Figure 1 This is a schematic diagram of TCP transmission based on existing technology, such as... Figure 1 As shown, a TCP connection can be established between the sending and receiving ends, and the established TCP connection can be used for data transmission between the sending and receiving ends.

[0003] in addition, Figure 2 This is a schematic diagram of a TCP proxy transmission based on existing technology, such as... Figure 2 As shown, a TCP proxy generally refers to inserting a proxy device between the sending and receiving ends of network communication. The proxy device establishes TCP connections with both the sending and receiving ends and forwards application layer protocol data running on top of the TCP protocol, such as an HTTP proxy (an intermediate server used to transmit HTTP requests and responses between clients and target servers).

[0004] Furthermore, since the TCP protocol is a reliable transmission protocol, the sender and receiver determine their respective send and receive windows, as well as the TCP window scale, when establishing a TCP connection. When transmitting data based on the TCP connection, the sender and receiver dynamically adjust the TCP receive window according to the current network status and the speed at which the application layer reads TCP data, in order to obtain a good data transmission speed and make full use of bandwidth.

[0005] However, when a proxy device intervenes, it breaks the original TCP connection. In scenarios where the network quality on both sides differs greatly, the number of concurrent connections is high, and especially when the proxy device's own resources (such as memory and CPU) are limited, how to balance the transmission speed of the TCP connections on both sides and ensure a good TCP proxy effect requires coordination from the proxy device, which is a great challenge for the proxy device.

[0006] Related technologies determine the size of the TCP network proxy's receive window by obtaining the size of the UE (User Equipment), the first delay between the TCP network proxy and the UE, and the second delay between the TCP network proxy and the Internet server. However, since network quality is dynamic, the TCP window also needs to be dynamically adjusted. Therefore, relying solely on the initial receive window size and delay of the UE device can only determine the initial window size of the TCP network proxy device at the initial moment. Furthermore, once network quality fluctuates, the related technologies cannot adjust the proxy device's window in a timely manner, which may frequently result in zero windows, leading to TCP connection blocking and other situations, thus resulting in low efficiency in transmitting data using the TCP Transmission Control Protocol.

[0007] There is currently no effective solution to the problem that it is difficult to adjust the size of the receiving window of the proxy device in a timely manner, which can easily lead to the blocking of TCP connections between the proxy device and the sending and receiving ends, resulting in low efficiency of data transmission using the TCP Transmission Control Protocol.

Then, the target request sent by the sending device is responded to through the adjusted receive window of the first socket, and the target packet is sent to the receiving device. This allows for timely adjustment of the receive window size of the proxy device and avoids blocking of the TCP connection between the proxy device and the sending and receiving ends, ensuring the stability of the TCP proxy and thus improving the efficiency of data transmission using the TCP Transmission Control Protocol.

[0039] For ease of description, the following explains some of the nouns or terms used in the embodiments of this application:

[0040] A socket is a communication mechanism in computer networks that allows processes on different computers to communicate. Through sockets, data can be sent and received over a network, enabling data exchange between processes.

[0041] CPU: The full name is Central Processing Unit. It is an important component of a computer and is also called a processor or microprocessor. It is the computing and control center of a computer and determines the computer's processing power and response speed.

[0042] The present invention will now be described in conjunction with preferred implementation steps. Figure 3 This is a flowchart of a data processing method provided according to an embodiment of this application, such as... Figure 3 As shown, the method includes the following steps:

[0043] Step S301: When the proxy device receives the target request sent by the sending device, it obtains the length of the receive queue of the first socket and the length of the send queue of the second socket. The target request is used to request the sending of the target message to the receiving device, the receive queue is used to receive the target message, and the send queue is used to send the target message.

[0044] For example, Figure 4 This is a schematic diagram of an optional data processing method provided according to an embodiment of this application, and the aforementioned transmitting device can be... Figure 4 The sending end in the middle, and the sending end can be used to send a message request (the aforementioned target request) to the proxy device, and then the proxy device sends the message request (the aforementioned target request) to the receiving end (the aforementioned receiving device); the aforementioned receiving device can be Figure 4 The receiving end in the middle, and the receiving end can be used to receive message requests sent by the sending end, and return messages to the proxy device based on the message requests, and then the proxy device sends the messages returned by the receiving end to the sending end; the first socket mentioned above can be Figure 4 The sock0 socket in the middle, and such Figure 4 As shown, the proxy device and the sending end establish a TCP connection through sock0 (the first socket mentioned above); the second socket mentioned above can be... Figure 4 The sock1 socket in the middle, and such Figure 4 As shown, the proxy device and the receiving end establish a TCP connection through sock1 (the second socket mentioned above); the receive queue of the first socket mentioned above can be the receive queue of sock0 (the first socket mentioned above); the send queue of the second socket mentioned above can be the send queue of sock1 (the second socket mentioned above).

[0045] For example, such as Figure 4As shown, in a TCP proxy scenario, two user-space sockets are created (i.e., sock0 and sock1 are created) and associated with each other. The receive window of sock0 (the first socket mentioned above) can be jointly controlled by the receive queue length of sock0 (the first socket mentioned above) and the send queue length of sock1 (the second socket mentioned above).

[0046] sock0_rcv_wnd=default_wnd-(sock0_rcv_queue+sock1_send_queue)

[0047] Wherein, sock0_rcv_wnd represents the size of the receive window of sock0, default_wnd represents the size of the default window, and default_wnd can be agreed to have a default value of 128KB, sock0_rcv_queue represents the length of the receive queue of sock0, and sock1_send_queue represents the length of the send queue of sock1.

[0048] Step S302: Obtain the data information set of the proxy device, wherein the data information set includes at least: the CPU utilization rate of the proxy device, the memory utilization rate of the proxy device, and the number of packets that the proxy device can currently receive.

[0049] For example, the aforementioned data set may include real-time CPU utilization, memory utilization, and remaining packet count of the proxy device. Therefore, the real-time system status of the proxy device can be obtained, including CPU utilization, memory utilization, and remaining packet count (the number of packets the proxy device can currently receive).

[0050] Step S303: Adjust the size of the receiving window of the first socket according to the length of the receiving queue of the first socket, the length of the sending queue of the second socket, and the data information set of the proxy device to obtain the adjusted receiving window of the first socket.

[0051] For example, the size of the receive window of sock0 can be calculated and adjusted based on the receive queue length of sock0 (the first socket mentioned above), the send queue length of sock1 (the second socket mentioned above), and the CPU utilization, memory utilization, and remaining number of packets of the proxy device.

[0052] Step S304: Respond to the target request through the adjusted receiving window of the first socket and send the target message to the receiving device.

[0053] For example, after adjusting the size of the receive window of sock0 (the first socket mentioned above), the message request (the target request mentioned above) sent by the sender (the sending device mentioned above) can be sent to the receiver (the receiving device mentioned above) based on the adjusted receive window of sock0.

[0054] Through the steps S301 to S304 described above, by obtaining the length of the receive queue of the first socket, the length of the send queue of the second socket, and the data information set of the proxy device, and adjusting the size of the receive window of the first socket according to the length of the receive queue of the first socket, the length of the send queue of the second socket, and the data information set of the proxy device, the adjusted receive window of the first socket is obtained. Then, the target request sent by the sending device is responded to through the adjusted receive window of the first socket, and the target packet is sent to the receiving device. In this way, the size of the receive window of the proxy device can be adjusted in a timely manner, and the TCP connection between the proxy device and the sending and receiving ends can be avoided, ensuring the stability of the TCP proxy, thereby improving the efficiency of data transmission using the TCP Transmission Control Protocol.

[0055] Optionally, in the data processing method provided in this application embodiment, adjusting the size of the receiving window of the first socket based on the length of the receiving queue of the first socket, the length of the sending queue of the second socket, and the data information set of the proxy device to obtain the adjusted receiving window of the first socket includes: determining the size of the receiving window of the first socket based on the length of the receiving queue of the first socket and the length of the sending queue of the second socket; and adjusting the size of the receiving window of the first socket based on the data information set of the proxy device to obtain the adjusted receiving window of the first socket.

[0056] For example, the initial size of the receive window of sock0 (the first socket mentioned above) can be calculated first based on the receive queue length of sock0 (the first socket mentioned above) and the send queue length of sock1 (the second socket mentioned above). Then, the initial size of the receive window of sock0 (the first socket mentioned above) can be adjusted according to the CPU utilization, memory utilization and remaining number of packets of the proxy device, and the adjusted receive window of sock0 can be obtained.

[0057] The above method allows for dynamic adjustment of the TCP receive window size based on the device's real-time system status.

[0058] Optionally, in the data processing method provided in this application embodiment, determining the size of the receiving window of the first socket based on the length of the receiving queue of the first socket and the length of the sending queue of the second socket includes: obtaining the initial size of the receiving window of the first socket; and determining the size of the receiving window of the first socket based on the initial size of the receiving window of the first socket, the length of the receiving queue of the first socket, and the length of the sending queue of the second socket.

[0059] In a TCP proxy scenario, two user-space sockets are created (i.e., sock0 and sock1), and these two sockets are associated. The receive window of sock0 (the first socket mentioned above) can be jointly controlled by the receive queue length of sock0 (the first socket mentioned above) and the send queue length of sock1 (the second socket mentioned above).

[0060] sock0_rcv_wnd=default_wnd-(sock0_rcv_queue+sock1_send_queue)

[0061] Wherein, sock0_rcv_wnd represents the size of the receive window of sock0, default_wnd represents the size of the default window (corresponding to the initial size of the receive window mentioned above), and default_wnd can be agreed to have a default value of 128KB, sock0_rcv_queue represents the length of the receive queue of sock0, and sock1_send_queue represents the length of the send queue of sock1.

[0062] Similarly, the receive window of sock1 (the second socket mentioned above) is jointly controlled by the receive queue length of sock1 (the second socket mentioned above) and the send queue length of sock0 (the first socket mentioned above):

[0063] sock1_rcv_Wnd=default_wnd-(sock1_rcv_queue+sock0_send_queue)

[0064] Wherein, sock1_rcv_wnd represents the size of the receive window of sock1, default_wnd represents the size of the default window (corresponding to the initial size of the receive window mentioned above), and default_wnd can be agreed to have a default value of 128KB, sock1_rcv_queue represents the length of the receive queue of sock1, and sock0_send_queue represents the length of the send queue of sock0.

[0065] In summary, even when the network quality on both sides is inconsistent, the TCP connections on both sides remain independent. Based on the reliable transmission characteristics of TCP connections, reliable data transmission can be guaranteed. At the same time, by dynamically adjusting the receive windows of sock0 and sock1, the transmission speed of TCP connections on both sides can be balanced, avoiding situations where TCP connection data transmission is blocked due to slow application layer processing.

[0066] Optionally, in the data processing method provided in this application embodiment, adjusting the size of the receiving window of the first socket based on the data information set of the proxy device to obtain the adjusted receiving window of the first socket includes: determining whether the number of packets that the proxy device can currently receive in the data information set is less than a preset number; if the number of packets that the proxy device can currently receive in the data information set is less than the preset number, then adjusting the size of the receiving window of the first socket to 0; if the number of packets that the proxy device can currently receive in the data information set is not less than the preset number, then determining whether the CPU utilization rate of the proxy device in the data information set is greater than a first preset utilization rate, and determining whether the memory utilization rate of the proxy device in the data information set is greater than a second preset utilization rate, and obtaining a determination result; adjusting the size of the receiving window of the first socket according to the determination result to obtain the adjusted receiving window of the first socket.

[0067] For example, when dynamically adjusting the TCP window, it can first be determined whether the remaining number of packets on the proxy device is less than the threshold (the aforementioned preset number). If the remaining number of packets on the proxy device is less than the threshold (the aforementioned preset number), the receive window size of sock0 (the aforementioned first socket) can be set to 0. If the remaining number of packets on the proxy device is not less than the threshold (the aforementioned preset number), it can then be determined whether the CPU utilization of the proxy device is greater than 90% (the aforementioned first preset utilization rate) and whether the memory utilization of the proxy device is greater than 95% (the aforementioned second preset utilization rate). The receive window of sock0 (the aforementioned first socket) can then be dynamically adjusted based on the results of both (CPU utilization and memory utilization). Furthermore, the values ​​corresponding to the aforementioned first preset utilization rate and the aforementioned second preset utilization rate can be the same or different. That is, the aforementioned first preset utilization rate and the aforementioned second preset utilization rate can both be set to 90%, or the aforementioned first preset utilization rate can be set to 90%, and the aforementioned second preset utilization rate can be set to 95%.

[0068] With the above scheme, when the number of remaining packets in the system is lower than the threshold, sock0 can close the TCP window and reject new TCP connections, preventing packet resources from being further consumed and affecting other TCP connections.

[0069] Optionally, in the data processing method provided in this application embodiment, adjusting the size of the receiving window of the first socket according to the judgment result to obtain the adjusted receiving window of the first socket includes: if the CPU utilization rate of the proxy device in the data information set is greater than a first preset utilization rate and the memory utilization rate of the proxy device in the data information set is not greater than a second preset utilization rate, then the receiving window of the first socket is reduced to a target value; if the CPU utilization rate of the proxy device in the data information set is not greater than the first preset utilization rate and the memory utilization rate of the proxy device in the data information set is greater than the second preset utilization rate, then the receiving window of the first socket is reduced to a target value; if the CPU utilization rate of the proxy device in the data information set is not greater than the first preset utilization rate and the memory utilization rate of the proxy device in the data information set is not greater than the second preset utilization rate, then the size of the receiving window of the first socket is not adjusted; if the CPU utilization rate of the proxy device in the data information set is greater than the first preset utilization rate and the memory utilization rate of the proxy device in the data information set is greater than the second preset utilization rate, then the size of the receiving window of the first socket is adjusted based on the CPU utilization rate and the memory utilization rate of the proxy device to obtain the adjusted receiving window of the first socket.

[0070] For example, when the proxy device's CPU utilization is greater than 90% (the first preset utilization rate mentioned above) and the proxy device's memory utilization is not greater than 95% (the second preset utilization rate mentioned above), sock0 can multiply the original window by a coefficient. That is, when the CPU utilization exceeds 90%, the higher the CPU utilization, the smaller the TCP window. When the proxy device's CPU utilization is not greater than 90% (the first preset utilization rate mentioned above) and the proxy device's memory utilization is greater than 95% (the second preset utilization rate mentioned above), sock0 can multiply the original window by a coefficient. That is, when the memory utilization exceeds... If the CPU utilization is 95%, then the higher the memory utilization, the smaller the TCP window will be. When the CPU utilization of the proxy device is no greater than 90% (the first preset utilization rate mentioned above) and the memory utilization of the proxy device is no greater than 95% (the second preset utilization rate mentioned above), then there is no need to adjust the receive window of sock0 (the first socket mentioned above). When the CPU utilization of the proxy device is greater than 90% (the first preset utilization rate mentioned above) and the memory utilization of the proxy device is greater than 95% (the second preset utilization rate mentioned above), then the receive window size of sock0 (the first socket mentioned above) can be adjusted according to the CPU utilization and memory utilization of the proxy device.

[0071] By using the above method, when the system's CPU utilization or memory utilization exceeds the preset value, the TCP window can be reduced, thereby ensuring system stability and preventing impact on already proxied TCP connections.

[0072] Optionally, in the data processing method provided in this application embodiment, adjusting the size of the receiving window of the first socket based on the CPU utilization and memory utilization of the proxy device to obtain the adjusted receiving window of the first socket includes: calculating the size of the receiving window of the first socket based on the CPU utilization of the proxy device to obtain a first size corresponding to the receiving window; calculating the size of the receiving window of the first socket based on the memory utilization of the proxy device to obtain a second size corresponding to the receiving window; comparing the values ​​corresponding to the first size and the second size to obtain the smaller value of the first size and the second size; and adjusting the size of the receiving window of the first socket to the smaller value of the first size and the second size to obtain the adjusted receiving window of the first socket.

[0073] For example, when the CPU utilization of the proxy device is greater than 90% (the first preset utilization rate mentioned above) and the memory utilization of the proxy device is greater than 95% (the second preset utilization rate mentioned above), then sock0 can multiply the original window by a coefficient and determine the receiving window size of sock0 (the first socket mentioned above) calculated based on the CPU utilization rate and the receiving window size of sock0 (the first socket mentioned above) calculated based on the memory utilization rate. Then, the smaller of the two calculated receiving windows is taken as the final receiving window of sock0 (the first socket mentioned above).

[0074] By using the above scheme, when the system's CPU utilization and memory utilization both exceed the preset values, a smaller window can be used as the final receive window for sock0, thereby ensuring system stability and preventing impact on already proxied TCP connections.

[0075] Optionally, in the data processing method provided in this application embodiment, responding to the target request through the adjusted receiving window of the first socket and sending the target message to the receiving device includes: obtaining the sequence number of the target message, and determining whether the adjusted receiving window of the first socket allows receiving the target message based on the sequence number of the target message; if the adjusted receiving window of the first socket does not allow receiving the target message, then prohibiting the sending of the target message to the receiving device; if the adjusted receiving window of the first socket allows receiving the target message, then adding the target message to the receiving queue of the first socket; reading the target message from the receiving queue of the first socket and adding the target message to the sending queue of the second socket; and sending the target message in the sending queue of the second socket to the receiving device.

[0076] For example, Figure 4 This is a schematic diagram of an optional data processing method provided according to an embodiment of this application, such as... Figure 4As shown, the proxy device establishes a TCP connection with the sending end through sock0 and with the receiving end through sock1. Optional data processing methods include the following steps:

[0077] (1) The sending end sends a request to the proxy device;

[0078] (2) The agent device calculates and adjusts its own receiving window. When the received message sequence number is within the range allowed by the receiving window, it allows the receiving of the message and puts it into the receiving queue of sock0.

[0079] (3) The application layer reads the receive queue of sock0, reads in order, retrieves the message, and puts the message into the send queue of sock1 after processing.

[0080] (4) The proxy device sends the message to the receiving end through sock1;

[0081] (5) The response message returned by the receiving end arrives at the agent device;

[0082] (6) The agent device calculates and adjusts its own receiving window. When the received message sequence number is within the range allowed by the receiving window, it allows the receiving of the message and puts it into the receiving queue of sock1.

[0083] (7) The application layer reads the receive queue of sock1, reads in order, retrieves the message, and puts the message into the send queue of sock0 after processing.

[0084] (8) The agent device sends the message to the sender through sock0.

[0085] In summary, creating two user-space sockets can prevent TCP connection blocking and provide users with a high-performance, stable TCP proxy solution.

[0086] Optionally, in the data processing method provided in this application embodiment, after responding to the target request through the adjusted receiving window of the first socket and sending the target message to the receiving device, the method further includes: when it is detected that the first socket sends target notification information to the sending device within a preset time period, the size of the receiving window of the first socket is recalculated to obtain the recalculated size of the receiving window of the first socket, wherein the preset time period is the time period after the sending device sends the target request and before the receiving device receives the target message, and the target notification information is used to notify the sending device that the size of the receiving window of the first socket is 0; if the recalculated size of the receiving window of the first socket is greater than the preset value, a window update message is sent to the sending device through the first socket, wherein the window update message is used to notify the sending device that the size of the receiving window of the first socket is not 0.

[0087] For example, Figure 5 This is a schematic diagram of the active notification window update in an embodiment of this application, such as... Figure 5 As shown, after processing the packets in the sock1 receive queue, the proxy device actively checks if sock0 has recently had a zero window and recalculates the sock0 receive window size (since the sock0 receive queue has been cleared, the sock0 receive window is likely to be updated and expanded). If sock0 recently advertised a zero window and its current window has been updated (assuming the preset value is 16KB, meaning the recalculated sock0 receive window size exceeds 16KB), then sock0 can proactively send a window update message to the sender, allowing the TCP connection to resume data transmission. Conversely, if sock0 recently advertised a zero window, but the recalculated sock0 receive window size does not exceed 16KB, then sock0 cannot proactively send a window update message to the sender.

[0088] The above solution can prevent TCP connections from being idle for extended periods, thereby significantly improving data transmission efficiency.

[0089] For example, this embodiment provides a scheme for controlling the TCP receive window in proxy mode. By creating a user-space TCP socket and associating it with sockets on both sides, and combining the real-time CPU utilization, memory utilization, and the number of remaining available packets in the system, the TCP window is dynamically adjusted. When the TCP connection has a zero window, a TCP window update message is actively sent to avoid the TCP connection being in a waiting or congested state for a long time. This allows the network proxy device to have good TCP proxy creation performance and throughput in high-concurrency scenarios.

[0090] in addition, Figure 4 This is a schematic diagram of an optional data processing method provided according to an embodiment of this application, such as... Figure 4 As shown, the proxy device establishes a TCP connection with the sending end through sock0 and with the receiving end through sock1. Optional data processing methods include the following steps:

[0091] (1) The sending end sends a request to the proxy device;

[0092] (2) The agent device calculates and adjusts its own receiving window. When the received message sequence number is within the range allowed by the receiving window, it allows the receiving of the message and puts it into the receiving queue of sock0.

[0093] (3) The application layer reads the receive queue of sock0, reads in order, retrieves the message, and puts the message into the send queue of sock1 after processing.

[0094] (4) The proxy device sends the message to the receiving end through sock1;

[0095] (5) The response message returned by the receiving end arrives at the agent device;

[0096] (6) The agent device calculates and adjusts its own receiving window. When the received message sequence number is within the range allowed by the receiving window, it allows the receiving of the message and puts it into the receiving queue of sock1.

[0097] (7) The application layer reads the receive queue of sock1, reads in order, retrieves the message, and puts the message into the send queue of sock0 after processing.

[0098] (8) The agent device sends the message to the sender through sock0.

[0099] For example, associating two sockets can be specifically done as follows:

[0100] For example, such as Figure 4 As shown, in a TCP proxy scenario, two user-space sockets are created (i.e., sock0 and sock1 are created) and associated with each other. The receive window of sock0 can be controlled by both the receive queue length of sock0 and the send queue length of sock1.

[0101] sock0_rcv_wnd=default_wnd-(sock0_rcv_queue+sock1_send_queue)

[0102] Wherein, sock0_rcv_wnd represents the size of the receive window of sock0, default_wnd represents the size of the default window, and default_wnd can be agreed to have a default value of 128KB, sock0_rcv_queue represents the length of the receive queue of sock0, and sock1_send_queue represents the length of the send queue of sock1.

[0103] Similarly, the receive window of sock1 is jointly controlled by the receive queue length of sock1 and the send queue length of sock0:

[0104] sock1_rcv_wnd=default_wnd-(sock1_rcv_queue+sock0_send_queue)

[0105] Wherein, sock1_rcv_wnd represents the size of the receive window of sock1, default_wnd represents the size of the default window, and default_wnd can be agreed to have a default value of 128KB, sock1_rcv_queue represents the length of the receive queue of sock1, and sock0_send_queue represents the length of the send queue of sock0.

[0106] In this way, even when the network quality on both sides is inconsistent, the TCP connections on both sides remain independent. Based on the reliable transmission characteristics of TCP connections, reliable data transmission can be guaranteed. At the same time, by dynamically adjusting the receive windows of sock0 and sock1, the transmission speed of TCP connections on both sides can be balanced, avoiding situations where TCP connection data transmission is blocked due to slow application layer processing.

[0107] For example, dynamically adjusting the TCP window can be done as follows:

[0108] When multiple senders initiate TCP connection requests simultaneously, resulting in a large number of concurrent TCP connections, the receive and send queues of both sockets are initially idle. At this time, sock0 calculates the TCP receive window as default_wnd (which can be agreed upon as a default value of 128KB). However, given the large number of concurrent TCP connections and the limited remaining resources of the proxy device, it is inappropriate for sock0 to announce a 128KB window to the senders. This can easily cause TCP connection congestion and further consume the system resources of the proxy device, even affecting the data transmission of other TCP connections.

[0109] In this embodiment, the real-time system status of the agent device can be fully considered, including CPU utilization (denoted by c, and 0% ≤ c ≤ 100%), memory utilization (denoted by m, and 0% ≤ m ≤ 100%), and remaining packet count (denoted by p, and p should not be lower than the threshold P). thresh (And this threshold is configurable), and the receive window of the TCP connection can be dynamically calculated in the following way.

[0110]

[0111] Where sock0_rcv_wnd represents the size of the receive window of sock0, K m and K c All represent coefficients, and wnd represents the size of the default window (base window).

[0112] (1) When p <P thresh That is, when the number of remaining packets in the system is lower than the threshold, sock0 should close the TCP window, reject new TCP connections, and prevent packet resources from being further consumed, thus affecting other TCP connections;

[0113] (2) When m≥90% and c<90%, sock0 should be multiplied by a coefficient based on the original window. When the memory utilization exceeds 90%, the higher the memory utilization, the smaller the TCP window will be.

[0114] (3) When m < 90% and c ≥ 90%, sock0 should be multiplied by a coefficient based on the original window. When the CPU utilization exceeds 90%, the higher the CPU utilization, the smaller the TCP window should be.

[0115] (4) When m≥90% and c≥90%, sock0 should be multiplied by a coefficient based on the original window size, and the smaller window size should be selected.

[0116] For example, the process of proactively notifying the window to update can be specifically as follows:

[0117] In practical applications, due to various influencing factors (such as slow application layer processing leading to a backlog in the receive queue), the TCP zero-window phenomenon is inevitable. When sock0 has a TCP zero window (i.e., sock0 announces a receive window of 0 to the sender), it means that the sender can no longer send data to the proxy device. According to the inherent TCP mechanism, the sender can only send a window probe packet to the proxy device after 200ms. If the proxy device has already finished processing the received packets, it will update the receive window of sock0 and announce it to the sender. However, under normal circumstances, the proxy device has already finished processing the data in the sock1 receive queue within 200ms and is already capable of receiving data again. If the proxy device keeps passively updating the window, there will be no data transmission on the TCP connection during those 200ms, resulting in inefficient data transmission.

[0118] For example, Figure 5 This is a schematic diagram of the active notification window update in an embodiment of this application, such as... Figure 5 As shown, after the proxy device completes the message processing of the sock1 receive queue, it actively checks whether sock0 has recently had a zero window and recalculates the receive window size of sock0 (since the sock0 receive queue has been cleared at this time, the sock0 receive window is likely to be updated and expanded). If sock0 has recently announced a zero window and the current sock0 window has been updated, then sock0 actively sends a window update message to the sender, so that the TCP connection resumes data transmission, avoids the TCP connection being idle for a long time, and can greatly improve data transmission efficiency.

[0119] For example, the methods provided in the embodiments of this application can be applied to network proxy devices (including but not limited to network traffic security devices, network data forwarding devices, network traffic analysis devices, and network traffic management devices, such as FW (Firewall) / NGFW (Next-Generation Firewall), IDS (Intrusion Detection System) / IPS (Intrusion Prevention System), WAF (Web Application Firewall), ADC (Application Delivery Controller, load balancing refers to a technology that distributes network traffic to different application servers to achieve network load balancing), BDS (a platform for network security protection), etc.), and are also applicable to virtualized network functions or virtualized network devices (including but not limited to virtualized network traffic security functions or devices, virtualized network data forwarding functions or devices, virtualized network traffic analysis functions or devices, and virtualized network traffic management functions or devices).

[0120] Moreover, it can be applied to network proxy devices to proxy TCP connections based on user-space TCP sockets. On this TCP proxy basis, various application layer functions can be implemented.

[0121] For example, this embodiment provides users with a high-performance and stable TCP proxy solution by creating a user-space TCP socket, and has the following beneficial effects:

[0122] (1) It has a wide range of applications

[0123] It is suitable for various network devices, security devices, network function software, and network security software, including bare metal, virtualization, and container platforms.

[0124] (2) Stable TCP proxy can be achieved

[0125] By associating sockets on both sides, dynamically adjusting the TCP window, and proactively sending window update messages when the TCP connection reaches zero window, multiple measures are taken to ensure the stability of the TCP proxy and high-performance data transmission.

[0126] Furthermore, TCP connection proxying can be implemented by creating user-space TCP sockets; and TCP receive windows can be dynamically adjusted by associating sockets on both sides and using an efficient associative window adjustment algorithm; in addition, when a zero window occurs, efficient data transmission of TCP connections can be achieved by actively sending window update messages.

[0127] In summary, the data processing method provided in this application, when the proxy device receives a target request sent by the sending device, obtains the length of the receive queue of the first socket and the length of the send queue of the second socket. The target request is used to request the sending of a target message to the receiving device, the receive queue is used to receive the target message, and the send queue is used to send the target message. The method also obtains a data information set of the proxy device, which includes at least: the CPU utilization rate of the proxy device, the memory utilization rate of the proxy device, and the number of messages that the proxy device can currently receive. Based on the length of the receive queue of the first socket, the length of the send queue of the second socket, and the data information set of the proxy device, the method adjusts the size of the receive window of the first socket to obtain the adjusted receive window. Finally, the method responds to the target request through the adjusted receive window of the first socket and sends the target message to the receiving device. This solves the problem in related technologies where it is difficult to adjust the size of the receive window of the proxy device in a timely manner, leading to potential blocking of the TCP connection between the proxy device and the sending and receiving ends, and consequently, low efficiency in transmitting data using the TCP Transmission Control Protocol. By obtaining the length of the receive queue of the first socket, the length of the send queue of the second socket, and the data information set of the proxy device, and adjusting the size of the receive window of the first socket according to the length of the receive queue of the first socket, the adjusted receive window of the first socket is obtained. Then, the target request sent by the sending device is responded to through the adjusted receive window of the first socket, and the target packet is sent to the receiving device. This allows for timely adjustment of the receive window size of the proxy device and avoids blocking of the TCP connection between the proxy device and the sending and receiving ends, ensuring the stability of the TCP proxy and thus improving the efficiency of data transmission using the TCP Transmission Control Protocol.

By obtaining the length of the receive queue of the first socket, the length of the send queue of the second socket, and the data information set of the proxy device, and adjusting the size of the receive window of the first socket according to the length of the receive queue of the first socket, the adjusted receive window of the first socket is obtained. Then, the target request sent by the sending device is responded to through the adjusted receive window of the first socket, and the target packet is sent to the receiving device. This allows for timely adjustment of the receive window size of the proxy device and avoids blocking of the TCP connection between the proxy device and the sending and receiving ends, ensuring the stability of the TCP proxy and thus improving the efficiency of data transmission using the TCP Transmission Control Protocol.
