[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0028] In the related art, when the DPU chip performs flow control, it controls the transmission of each message in the flow in order through polling scheduling. Since the control flow is real-time and bursty, a large number of control messages will be generated in a short period of time. Therefore, when the polling time interval is long or the processing speed cannot keep up with the message generation speed, some control messages may not be transmitted in time and messages may accumulate. However, as the accumulated number of control messages continues to increase, the delay time of sending will also increase accordingly, which will affect the performance of the DPU chip.

[0029] In view of this, the embodiments of the present disclosure provide a flow control method to effectively manage and control the transmission of control messages so that they can be transmitted at the appropriate time while meeting bandwidth restrictions, thereby effectively reducing the possibility of delayed transmission of control messages and improving transmission accuracy and efficiency.

[0030] According to an embodiment of the present disclosure, a flow control method embodiment 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 a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] In this embodiment, a flow control method is provided, which can be used for electronic devices such as mobile phones and tablet computers that deploy the above-mentioned DPU. Figure 1 is a flow chart of a flow control method according to an embodiment of the present disclosure, such as Figure 1 As shown, the process includes the following steps:

[0032] Step S101, determining control messages to be transmitted in a control traffic queue.

[0033] Control messages refer to messages used to control and manage data transmission in communication networks, such as establishing connections, transmitting control information, etc. To ensure that control messages can be transmitted in a timely manner, control messages to be transmitted are identified and determined from the control traffic queue so that the transmission control information of the control messages can be clarified later, thereby enabling better targeted control.

[0034] In some optional examples, the control message to be transmitted may be determined according to the corresponding priority. That is, the priority is set in advance according to the importance or urgency of the control message, and then the control message with a higher priority is selected as the message to be transmitted in the control flow queue, thereby helping to ensure that important control information can be transmitted first. In some other optional examples, the control message to be transmitted may be determined according to the order in which the control message enters the control flow queue. That is, the control message that enters the control flow queue first is selected as the control message to be transmitted first, thereby helping to improve the determination efficiency. The specific determination process of the control message can be determined by selecting a combination of one or more methods according to the specific scenario and needs, and is not limited here.

[0035] Step S102: determining transmission control information of the control message based on the message length of the control message and the control flow bandwidth information.

[0036] According to the message length, the data volume of the control message can be clearly determined. According to the control traffic bandwidth information, the relevant information of the bandwidth resources used when transmitting the control message can be clearly determined. The relevant information includes but is not limited to any one or more combinations of the following: the ratio between the bandwidth resources used when transmitting the control message and the overall bandwidth resources, the bandwidth amount that can be allocated to the control message, the upper limit of the transmission rate of the control message, and the bandwidth allocation of control messages of different priorities. Among them, by determining the ratio between the bandwidth resources used when transmitting the control message and the overall bandwidth resources, the bandwidth management and allocation can be better performed. By determining the bandwidth amount that can be allocated to the control message, it can be ensured that there are sufficient resources for transmission when transmitting the control message. By determining the upper limit of the transmission rate of the control message, it can be understood how fast the control message can be transmitted under specific bandwidth conditions to avoid exceeding the bandwidth limit and causing network congestion. By determining the bandwidth allocation of control messages of different priorities, it can help determine the bandwidth share that can be obtained by the control message of each priority, so as to ensure that the control message of high priority can be transmitted first.

[0037] Transmission control information is information used to perform targeted control on the transmission of control messages, including but not limited to the transmission duration and transmission rate of control messages. When the message length and control traffic bandwidth information are clear, the transmission control information of the control message is determined, which can ensure the reliability of the transmission control information, and then when the transmission of the control message is subsequently controlled based on the transmission control information, it can ensure that the control message can be transmitted in a timely manner within a reasonable bandwidth range.

[0038] Step S103, obtaining the current time series of the system.

[0039] The current time sequence is determined based on the current system time and is used to indicate the order of time. In order to determine the transmission timing of the control message, the current system time is converted into the current time sequence so that it can be read and recognized by the DPU chip. Then, the current time sequence can be used as a time reference to perform targeted control on the transmission of the control message.

[0040] Step S104: determining the transmission timing of the control message based on the comparison result between the transmission control information and the current time sequence.

[0041] Based on the comparison results of the transmission control information and the current time series, it can be determined whether the control message can be effectively transmitted under the current system time, and then the transmission timing of the control message can be determined in a targeted manner, which can not only ensure the normal operation of the network and the effective transmission of data, but also avoid unnecessary delays and waste of resources.

[0042] The flow control method provided in this embodiment can determine the transmission control information of the control message based on the message length of the control message and the control flow bandwidth information to ensure the rationality of the allocation of network resources, and then determine the transmission timing of the control message based on the comparison result between the transmission control information and the current time series corresponding to the current system time, which can effectively reduce the possibility of delayed transmission of the control message, thereby improving the transmission accuracy and efficiency.

[0043] In some optional embodiments, the current time series of the system is increased according to a preset step size, and the preset step size is determined based on the bus width of the system, thereby ensuring the time synchronization of various components or modules in the system, avoiding errors or anomalies caused by time inconsistencies, and making the increase method of the current time series more precise, which helps to improve the reliability and stability of the system.

[0044] In other optional implementations, the ratio between the preset step size and the bus width is a positive integer, which helps to improve the efficiency of determining the next time series. In addition, by determining the preset step size in this way, hardware resources can be better utilized to avoid waste of resources or uneven allocation, thereby better improving the resource utilization and overall performance of the system.

[0045] In some optional implementation scenarios, if the bus width of the system is 68 Byte, the preset step size may be 16 times the bus width, that is, the preset step size may be 1024 Byte. Preferably, the ratio between the preset step size and the bus width is an exponential multiple of 2, so that the binary characteristics of the computer system can be better utilized to improve the performance, efficiency and scalability of the system.

[0046] In this embodiment, a flow control method is provided, which can be used for electronic devices such as mobile phones and tablet computers that deploy the above-mentioned DPU. Figure 2 is a flow chart of a flow control method according to an embodiment of the present disclosure, such as Figure 2 As shown, the process includes the following steps:

[0047] Step S201: Determine the control message to be transmitted in the control flow queue. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0048] Step S202: determining transmission control information of the control message based on the message length of the control message and the control flow bandwidth information.

[0049] Specifically, the transmission control information includes a first start time sequence and a first end time sequence, and the above step S202 includes:

[0050] Step S2021, obtaining a first starting time sequence corresponding to the control message.

[0051] By acquiring the first start time sequence corresponding to the control message, the start sending time of the control message can be clarified, and then targeted control can be performed during subsequent transmission.

[0052] Among them, the first start time sequence is the same as the second end time sequence of the previous message, and the previous message is a message that is adjacent to the control message and has been transmitted. The second end time sequence can be understood as the stop time when the transmission of the previous message is completed. By determining the second end time sequence of the previous message as the first start time sequence corresponding to the control message, it can be ensured that the transmission of the control message is continuous in time, thereby effectively avoiding the occurrence of erroneous transmission or missed transmission.

[0053] Step S2022, based on the ratio of the message length and the control flow bandwidth information, obtain the time series interval.

[0054] Among them, the control traffic bandwidth information is used to characterize the transmission bandwidth ratio corresponding to the control traffic queue. The transmission bandwidth ratio can be predetermined or determined based on the actual quality of service (QoS) of the network, and can be determined specifically according to demand. Through the transmission bandwidth ratio, the available bandwidth resources corresponding to the control traffic queue can be clearly defined. For example, if the transmission bandwidth ratio is 20% and the total bandwidth is 100Mbps, then the bandwidth resources available to the control traffic queue are 20Mbps.

[0055] In order to determine the time taken to transmit the control message, the ratio between the message length and the transmission bandwidth ratio is determined, and then the time series interval required from the start of transmitting the control message to the stop of transmitting the control message is determined based on the ratio. This can ensure that the obtained time series interval meets the current network transmission performance, so that the reliability of the first termination time sequence corresponding to the control message can be guaranteed when it is subsequently determined.

[0056] In some examples, the numerical value corresponding to the ratio can be directly used as the time series interval, thereby helping to improve the efficiency of determining the time series interval. In other examples, the time series interval corresponding to the ratio can be obtained by performing analysis based on the ratio through a pre-trained model. The trained model is a model for analyzing the mapping relationship between the ratio between the message length and the transmission bandwidth ratio and the time series interval.

[0057] Step S2023: Obtain a first end time sequence corresponding to the control message based on the sum of the first start time sequence and the time sequence interval.

[0058] The first start time sequence can be understood as the transmission time sequence for starting to transmit the control message. The time sequence interval can be understood as the duration required to transmit the control message. By adding the first start time sequence to the time sequence interval and taking the sum as the first end time sequence corresponding to the control message, the transmission time sequence for stopping the transmission of the control message can be clearly determined. Then, combined with the transmission control information of the control message formed by the determined first start time sequence, it can be clearly determined when the control message should start to be transmitted and when the transmission should end, thereby achieving precise control of the control message transmission.

[0059] In some optional implementation scenarios, the expression of the first termination time sequence Finish_Time corresponding to the control message may be as follows:

[0060] Finish_Time=Start_Time+(Length / crtl_weight);

[0061] Among them, Start_Time represents the first starting time sequence corresponding to the control message, Length represents the message length of the control message, and crtl_weight represents the transmission bandwidth ratio.

[0062] Step S203, obtain the current time series of the system. For details, see Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0063] Step S204: determining the transmission timing of the control message based on the comparison result between the transmission control information and the current time sequence.

[0064] Specifically, the above step S204 includes:

[0065] Step S2041, if the first starting time sequence is greater than the current time sequence, a control message is sent;

[0066] Step S2042: Update the first start time sequence to the first end time sequence to obtain a second start time sequence corresponding to the next message.

[0067] Specifically, to ensure the timeliness of message transmission, the first start time sequence is compared with the current time sequence. If the first start time sequence is greater than the current time sequence, it indicates that the current system time is a suitable time and can be used to transmit the control message. Therefore, the control message is sent to ensure that the control information corresponding to the control message can be transmitted at the appropriate time.

[0068] To ensure the continuity of message sending, the first start time sequence is updated to the first end time sequence, and it is used as the second start time sequence corresponding to the next message to ensure the orderliness and continuity of the time sequence. Subsequently, control messages are sent according to the time sequence, which can better plan and allocate network resources and improve the management effectiveness of control message sending.

[0069] In some other optional implementations, the above step S204 further includes:

[0070] Step S2043: If the first starting time sequence is less than or equal to the current time sequence, wait for the transmission opportunity of the control message.

[0071] If the first starting time sequence is less than or equal to the current time sequence, it indicates that the current system time is relatively lagging. If the control message is transmitted at this time, it may affect the normal control logic of the system. Therefore, when it is determined that the first starting time sequence is less than or equal to the current time sequence, wait for the transmission opportunity of the control message and do not send the control message until the first starting time sequence is greater than the current time sequence, then send the control message, thereby improving the transmission effectiveness of the control message and ensuring the stability of the system performance.

[0072] The flow control method provided in this embodiment determines the transmission control information of the control message according to the message length and the transmission bandwidth ratio corresponding to the control flow queue, which helps to reasonably arrange the transmission order and time of the message, and then determines the transmission timing of the control message based on the comparison result between the transmission control information and the current time series, which can effectively improve the transmission efficiency and accuracy of the control flow, thereby effectively reducing the accumulation and delay of the control message and ensuring the stable operation of the system.

[0073] In some optional implementations, the above method further includes:

[0074] Step b1: If the first starting time sequence is less than or equal to the current time sequence, then determine the service message to be transmitted in the service traffic queue.

[0075] If the first starting time sequence is less than or equal to the current time sequence, it indicates that the control message is temporarily not transmitted in the current period. In order to improve the utilization rate of network resources, the business messages to be transmitted in the business traffic queue are determined to determine whether there is any pending business information that needs to be transmitted. Among them, the type of business message may include but is not limited to network messages or storage messages. Network messages are messages used to transmit various types of data and information in the network to ensure the normal operation of network communication; storage messages are messages used to perform operations related to data storage.

[0076] By determining the service messages to be transmitted in the service traffic queue, the allocation of network resources can be better planned and managed, which helps to improve the overall operation efficiency and performance of the network.

[0077] In some optional implementations, the service traffic queue includes multiple types of service traffic sub-queues, so the service packets to be transmitted in the service traffic queue can be determined by the following process:

[0078] Step b11, determining a first service traffic sub-queue to be processed currently from multiple types of service traffic sub-queues;

[0079] Step b12: extracting service messages from the first service traffic sub-queue.

[0080] Specifically, in network communications, there are multiple types of service traffic subqueues, which carry service traffic of corresponding service types. In order to effectively process these service traffic, it is necessary to determine the first service traffic subqueue that needs to be processed currently from the numerous service traffic subqueues. For example, it can be determined by polling, priority screening, or the load of each service traffic subqueue.

[0081] If the determination is made in a polling manner, each service traffic subqueue can be checked in a certain order. When it is the turn of a service traffic subqueue, it will be determined as the first service traffic subqueue to be processed to ensure that each service traffic subqueue has a chance to be processed. If the determination is made in a priority screening manner, the corresponding priority can be configured in advance for each service traffic subqueue, and then the service traffic subqueue with the highest priority is first selected as the first service traffic subqueue to be processed, so that network resources can be more reasonably allocated. If the determination is made based on the load conditions of each service traffic subqueue, the service traffic subqueue with a smaller load can be selected as the first service traffic subqueue for processing by evaluating the load conditions of each subqueue, which helps to balance the system load and improve the overall processing efficiency of the message.

[0082] After the first service traffic sub-queue is determined, service messages are extracted from the sub-queue so that the service messages can be processed in a timely manner to meet corresponding service requirements.

[0083] Step b2: sending a service message based on the service traffic bandwidth information.

[0084] Among them, the service traffic bandwidth information is used to characterize the transmission bandwidth ratio corresponding to the service traffic queue. According to the transmission bandwidth ratio corresponding to the service traffic queue, the broadband resources that can be occupied when transmitting service messages can be clearly identified, and then the transmission of service messages can be controlled by using this part of the broadband resources, which can ensure the rationality of network resource allocation and improve the utilization of network resources, thereby helping to improve the overall network performance.

[0085] Moreover, based on the comparison result between the first starting time sequence and the current time sequence, the transmission of control messages or business messages can be controlled, which can effectively isolate control traffic and business traffic, avoid mutual response, and effectively reduce the accumulation of control traffic, thereby effectively reducing delayed transmission and achieving the purpose of ensuring the transmission effectiveness of control traffic.

[0086] As one or more specific application embodiments of the embodiments of the present disclosure, the scheduling diagram of flow control can be as follows: Figure 3 As shown in the figure, the system can transmit control traffic and business traffic through the DPU chip. Business traffic includes network traffic and storage traffic.

[0087] For control traffic, the transmission control information of the control message can be determined based on the message length of the control message to be transmitted in the control traffic queue and the control traffic bandwidth information, and then the transmission timing of the control message can be determined based on the comparison result of the first starting time sequence in the transmission control information and the current time sequence of the system, so that the control message is sent when the first starting time sequence is greater than the current time sequence.

[0088] For example, assuming that the preset step size of the system time is 1024 bytes, the message length of the control message is 1024 bytes, and the transmission bandwidth ratio is 0.1, the transmission timing diagram of the control message can be as follows: Figure 4 As shown. Among them, the horizontal axis is the time sequence corresponding to the system time, and the vertical axis is the control traffic queue. For the control message in the control message, if the first start time sequence is 0, the first end time sequence is 10240. Among them, the first end time sequence = the first start time sequence + (message length / transmission bandwidth ratio) = 0 + 1024 / 0.1 = 10240. If the current system time is 1024, wait for the transmission opportunity of the control message and do not send the control message. If the current system time is 10240, send the control message, and update the first start time sequence to 10240 as the second start time sequence corresponding to the next control message. If the message length corresponding to the next control message is still 1024Byte, it can be determined that the second end time sequence corresponding to the next control message is 20480. By analogy, the transmission timing of each control message is determined respectively, and when the corresponding first starting time sequence is greater than the current time sequence, the corresponding control message is sent. This not only enables targeted control of the control message and ensures the orderly transmission of the control message, but also reduces the delay of the control message.

[0089] Combination Figure 4 The transmission timing diagram shown in FIG. 1 shows, the process of determining the transmission control information of the control message can be as follows: Figure 5 As shown in FIG. , each ellipse in the figure represents a control message.

[0090] If the first starting time sequence is less than or equal to the current time sequence, a polling method is adopted to determine the service message to be transmitted from the network traffic or storage traffic, and then the service message is sent based on the service traffic bandwidth information.

[0091] Through the above-mentioned traffic control method, not only can the bandwidth resources for control traffic be guaranteed, the occurrence of delayed transmission can be reduced, and the risk of network congestion can be reduced, but also the transmission isolation of control traffic and business traffic can be achieved, avoiding the transmission of control traffic from being interfered by business traffic, and ensuring that control information can be transmitted accurately and timely, which is conducive to ensuring that the entire network system can operate more reliably and provide better support for various applications and services.
