[0075] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. In addition, although the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in an order different from that here.

[0076] The terms "first" and "second" in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the term "comprising" and any of their variations are intended to cover non-exclusive protection. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0077] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0078] The following is an introduction to the data transmission method provided by the embodiment of the present application in conjunction with the accompanying drawings. Figure 1 As shown, the process of the data transmission method in the embodiment of the present application is described as follows:

[0079] Step 101: Map the kernel space address of the network card data to the user space;

[0080] In the embodiments of the present application, considering that the data transmission layer in the prior art is mainly based on the kernel protocol stack, during the data transmission process, the server first needs to transfer the data in the kernel space to the user space, and then transfer the data to the client through the user space, and the data transmission efficiency is low. Therefore, the present application virtualizes the network card function and maps the kernel space address of the network card data to the user space, so that the kernel data can be directly mapped to the user space, avoiding the copying or transmission of the kernel space to the user space data, and can effectively improve the data transmission efficiency.

[0081] In one possible implementation, after mapping the kernel space address of the network card data to the user space, the server can also establish a programmable white box protocol stack, and formulate transparent programmable capabilities (i.e., the preset programmable capabilities described below) in the user-mode protocol stack according to the different needs of different users, which are used to control the programmable white box protocol stack to perform corresponding functions. Among them, when establishing a programmable white box protocol stack, first initialize the interfaces of each layer of the white box protocol stack (for example, the link layer network interface and the transport layer network interface), and load the basic protocol stack module (for example, the link layer network function virtualization module), and then load the virtual network card data fast receiving module, receive the network card data and save the received network card data to the memory data queue, initialize the programmable module, and establish the basic module of the programmable white box protocol stack. Specifically, the steps for establishing the basic module of the programmable white box protocol stack are as follows: Figure 2 As shown:

[0082] Step 2-1: Initialize the network card virtualization module and map the kernel space address of the network card data to the user space;

[0083] Step 2-2: Establish a three-layer cache mechanism, load pre-storage and pre-fetch modules, and save the programming requirement chain customized by common clients;

[0084] Step 2-3: Create 1 / 2 of the server machine's memory as a large page;

[0085] Step 2-4: Create a user-mode protocol stack data storage module based on mbuf.

[0086] Step 2-5: Establish a data trigger module, bind the specific transmission events triggered by the network card data to a linked list, and trigger in real time.

[0087] In one possible implementation, when the server starts, it preferentially reads a list of clients that have applied for access and have programmable request attributes from a local file list (i.e., the programming data link saved in the aforementioned step 2-2), transmits data to each client according to its corresponding programming requirements, and while the server is running, listens to the client's programmable request through the user-mode protocol stack, and executes step 102 when a programmable request sent by the client is listened to.

[0088] Step 102: receiving a programmable request sent by a client based on a user space;

[0089] The programmable request includes programming requirements input by the user. For example, if the user only pays attention to hang-up events and SMS events, the user can input the hang-up events and SMS events as requirements into the client, and send a programmable request to the server through the client.

[0090] Step 103: Determine the target programmable capability corresponding to the programming requirement;

[0091] In an embodiment of the present application, the type of data required by the user can be determined according to the programming requirements, and the processing that needs to be performed on the data transmitted to the user can be determined (i.e., the target programmable capability corresponding to the programming requirements is determined). For example, if the programming requirements input by the user are hang-up events and SMS events, the server determines that the data transmitted to the user needs to be screened, and only the data corresponding to the hang-up events and SMS events are transmitted. The determined target programmable capability is, for example, the data tunnel programmable capability; if the programming requirement input by the user is data real-time, the server determines that the data transmitted to the user must be guaranteed to be real-time, and it is necessary to give priority to ensuring the transmission of data to the user, and there is no need to retransmit data when an abnormality occurs in the transmitted data, etc. The determined target programming capability is, for example, the real-time capability programmable capability; if the programming requirement input by the user is sampling data to view a certain type of overall data trend or overall behavior analysis, the server determines that the data transmitted to the user needs to ensure data quality, so part of the data can be discarded when transmitting data to reduce the transmission bandwidth, thereby ensuring the quality of data transmission, and the determined target programming capability is, for example, the data quality programmable capability.

[0092] Step 104: if the target programmable capability is a preset programmable capability, generating programmable parameters according to the target programmable capability;

[0093] Among them, the preset programmable capabilities include but are not limited to data tunnel programmable capabilities, data quality programmable capabilities, data throughput programmable capabilities, data delay rate programmable capabilities, real-time capability programmable capabilities and abnormal traffic audit programmable capabilities.

[0094] In an embodiment of the present application, when the target capability becomes a preset programmable capability, programmable parameters are generated according to the target programmable capability, such as programming mode parameters corresponding to different programmable capabilities. In a possible implementation, after generating the programmable parameters, it is also possible to determine whether the programmable parameters meet the programming parameter requirements. Specifically, the server can send the programmable parameters to the client, and the user determines whether the programmable parameters meet the requirements. If they meet, a response message that meets the requirements is returned to the server through the client. If they do not meet, a response message that does not meet the requirements is returned to the server. The server determines whether the programmable parameters meet the programming parameter requirements based on the response message. If the server determines that the programmable parameters meet the programming parameter requirements based on the response message sent by the client, step 105 is executed. In a possible implementation, if the server determines that the programmable parameters do not meet the programming parameter requirements based on the response message sent by the client, the programmable parameters can be regenerated based on the programming requirements and sent to the client for the user to confirm. If the number of regenerations exceeds the preset number, the programmable parameters will not be generated again, and data transmission will be performed directly based on the traditional method.

[0095] In a possible implementation, if the target programmable capability is not a preset programmable capability, or there is no special requirement in the programming requirement input by the user, the input operation interface of the Linux kernel is directly called to transmit data to the client.

[0096] Step 105: Transmit data to the client based on programmable parameters.

[0097] As mentioned above, the preset programmable capabilities include data tunnel programmable capability, data quality programmable capability, data throughput programmable capability, data delay rate programmable capability, real-time capability programmable capability and abnormal traffic audit programmable capability.

[0098] If the target programmable capability is the data tunnel programmable capability, the specific steps of transmitting data to the client based on the programmable parameters are as follows: Figure 3 As shown:

[0099] Step 3-1: Generate a data plane flow control strategy based on programmable parameters;

[0100] Step 3-2: Filter the collected traffic based on the data plane flow control strategy to obtain the target transmission data;

[0101] Step 3-3: Transmit the target transmission data to the client.

[0102] Specifically, a diversion module and a tunnel module are loaded in the programmable white box protocol stack, a data plane flow control strategy is generated, the collected traffic is filtered by the diversion module based on the data plane flow control strategy, the target collected traffic (i.e., the target transmission data) is obtained, the target transmission data is redirected to the vxlan dedicated tunnel (i.e., the tunnel module), and the target transmission data is transmitted to the client through the vxlan dedicated tunnel. For example, the programming requirement sent by user A through client A is an on-hook event. At this time, the tunnel module is a vxlan dedicated tunnel for transmitting the target transmission data of the on-hook event. If the programming requirement sent by user A through client A is an on-hook event and a text message event, the tunnel module at this time is a combination tunnel of the vxlan dedicated tunnel for transmitting the target transmission data of the on-hook event and the vxlan dedicated tunnel for transmitting the target transmission data of the text message event.

[0103] In some other embodiments, after loading the tunnel module, a client information hash table can be established in the tunnel module to mix and bind the client information and programming requirement events (i.e., establish a mapping relationship between the tunnel module and the client). In a possible implementation, before loading the tunnel module in the white box protocol stack, it can also be determined whether there is already a tunnel module corresponding to the client. If there is already a tunnel module corresponding to the client, the data is directly redirected to the tunnel module to transmit the data.

[0104] In the specific implementation process, the server combines specific types of data and channels by establishing a vxlan dedicated tunnel with a specific data combination, so that the client does not need to split the data, making data use simpler and efficiency greatly improved.

[0105] If the target programmable capability is data quality programmable capability, the specific steps for transmitting data to the client based on programmable parameters are as follows: Figure 4 As shown:

[0106] Step 4-1: Determine a target packet loss rate based on programmable parameters;

[0107] In the embodiment of the present application, after determining the target packet loss rate, the target transmission message can be obtained in two ways, namely, the target transmission message can be obtained in the ways corresponding to steps 4-2 to 4-3 and step 4-4 respectively.

[0108] Step 4-2: Determine the message parameters corresponding to the discarded message according to the target packet loss rate;

[0109] Step 4-3: discard the message based on the message parameters to obtain the target transmission message;

[0110] Step 4-4: randomly discard packets according to the target packet loss rate to obtain the target transmission packet;

[0111] Step 4-5: Transmit the target transmission message to the client.

[0112] Specifically, a data quality programming module is loaded in the programmable white box protocol stack, the TCP / UDP target packet loss rate is determined according to programmable parameters, a packet loss factor is injected into the TCP / UDP protocol, and the data quality programming module discards the message based on the packet loss in the TCP / UDP protocol (randomly discard or discard according to certain discard rules, that is, discard according to the message parameters corresponding to the discarded message). In a possible implementation, when using the TCP / UDP protocol to transmit messages, the message data quality (that is, the target packet loss rate) can be adjusted in real time to reduce the transmission bandwidth.

[0113] In the specific implementation process, when the user does not need the full amount of data, some messages are discarded, which lowers the threshold for users to use data and enables various application layers of the client to process the data.

[0114] If the target programmable capability is data delay programmable capability, the specific steps of transmitting data to the client based on programmable parameters are as follows: Figure 5 As shown:

[0115] Step 5-1: Determine whether the current network bandwidth is greater than or equal to a preset threshold;

[0116] Step 5-2: If the current network bandwidth is less than a preset threshold, determining the priority and message delay rate of each message among the multiple messages to be sent based on programmable parameters;

[0117] The message delay rate is used to indicate the time during which the corresponding message can be delayed in sending.

[0118] Step 5-3: Determine the transmission time of each message according to the priority of each message and the corresponding message delay rate;

[0119] Step 5-4: Transmitting a corresponding message to the client based on the transmission time.

[0120] Specifically, a delay programmable module and a timer module are loaded in the programmable white box protocol stack, a bidirectional linked list cache is established for the delay programmable module, a red-black tree cache is established for the timer module, and it is determined whether the current network bandwidth is greater than or equal to a preset threshold. If it is less than the preset threshold, it indicates that the current network bandwidth is insufficient, resources are tight, and the client itself begins to delay processing. At this time, the delay programmable module can be used to configure a delay queue based on the message priority, and the timer module can be used to trigger the TCP / UDP transmission message according to the transmission time of each message to ensure the optimal use of data.

[0121] In the specific implementation process, when the current network bandwidth is insufficient, resources are tight, and the client itself starts to process delays, by configuring a delay queue, the server bears the data pressure, making data application no longer difficult.

[0122] If the target programmable capability is a real-time programmable capability, a real-time capability module is loaded in the programmable white box protocol stack when transmitting data to the client based on programmable parameters, a multi-threaded asynchronous IO mechanism is enabled based on programmable parameters, and data is transmitted through multiple channels.

[0123] If the target programmable capability is data throughput programmable capability, the process asynchronous module is loaded in the programmable white box protocol stack when transmitting data to the client based on programmable parameters, and the multi-threaded asynchronous IO mechanism is enabled based on programmable parameters to ensure transmission throughput.

[0124] If the target programmable capability is the abnormal traffic audit programmable capability, the traffic control module is loaded in the programmable white box protocol stack when transmitting data to the client based on programmable parameters. When the traffic is abnormal based on programmable parameters, current limiting and peak shaving are performed to ensure the flexibility of data transmission.

[0125] Based on the same inventive concept, the embodiment of the present application provides a data transmission device, which can implement the functions corresponding to the aforementioned data transmission method. The data transmission device can be a hardware structure, a software module, or a hardware structure plus a software module.
