[0028] 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, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0029] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0030] A distributed storage system includes multiple data servers. In order to improve the disaster recovery capability of the distributed storage system, data is often required to be stored in multiple data servers in the form of multiple copies. This involves data transmission between data servers. However, during business peaks, the network bandwidth resources between data servers are often tight, which requires reasonable restrictions on the network bandwidth for data transmission.

[0031] In the related art, during the peak of business, the IP (Internet Protocol Address) of a certain client can be obtained first. Then, the priority corresponding to the IP of the client is obtained. If the priority corresponding to the IP of the client is higher, the network bandwidth between the data servers is increased, and the data corresponding to the IP of the client is stored preferentially.

[0032] However, not all data of the same client need to be processed urgently. Therefore, the accuracy of controlling the network bandwidth between data servers by the priority corresponding to the client IP is low.

[0033] It can be seen that how to improve the accuracy of controlling the network bandwidth between data servers is a problem that needs to be solved urgently.

[0034] In order to solve the above problems, this embodiment provides the following technical concept: first determine the priority of the business type corresponding to the data, and control the transmission speed of the data according to the priority of the business type, thereby realizing the limitation of the data transmission speed based on the business type, and improving the accuracy of controlling the traffic bandwidth.

[0035] The specific steps may include: first, in response to a first data server in a distributed storage system receiving a transmission request for target data, obtaining a transmission link for transmitting the target data, wherein the transmission request carries priority information of a service type to which the target data belongs; then, configuring a first priority parameter for the transmission link according to the priority information of the service type to which the target data belongs, by the first data server, wherein the first priority parameter indicates the priority of the transmission link at the transmission layer; finally, in response to transmitting the target data through the transmission link, configuring a second priority parameter for the target data according to the first priority parameter of the transmission link, by the first data server, so that the data transmission device allocates network bandwidth to the target data according to the second priority parameter, wherein the second priority parameter indicates the priority of the target data at the network layer.

[0036] Here, since the first priority parameter can be configured for different traffic according to the priority of its own business, when transmitting data, the first priority parameter is converted into the second priority parameter of the network layer. In this way, the switch can allocate the corresponding network bandwidth to the target data according to the second priority parameter of the network layer, thereby realizing the control of the priority of data transmission according to the business type, realizing more fine-grained traffic priority control, and thus improving the accuracy of controlling traffic bandwidth.

[0037] The application scenarios of the embodiments of the present disclosure are explained below:

[0038] The network traffic control method based on a distributed storage system provided by the embodiments of the present disclosure can be applied to data transmission scenarios of the distributed storage system. Figure 1 The following is a schematic diagram of an application scenario of a network traffic control method based on a distributed storage system provided by an embodiment of the present disclosure. Figure 1 As shown, the distributed storage system includes multiple data servers. The multiple data servers can be deployed in multiple computer rooms. For example, Figure 1 As shown, multiple data servers are deployed in computer room A, and multiple data servers are deployed in computer room B. When the first data server in computer room A needs to write data to the second data server in computer room B, the network flow control method based on the distributed storage system provided by the disclosed embodiment can be used to control the transmission speed of the data (that is, the speed of writing data). When the first data server in computer room A needs to read data from the second data server in computer room B, the network flow control method based on the distributed storage system provided by the disclosed embodiment can be used to control the transmission speed of the data (that is, the speed of reading data). The network flow control method based on the distributed storage system provided by the disclosed embodiment is described in detail below using a detailed embodiment.

[0039] Figure 2 The present invention provides a flow chart of a network traffic control method based on a distributed storage system. The network traffic control method is applied to a distributed storage system, which includes multiple data servers. Figure 2 As shown, the method includes:

[0040] S201. In response to a first data server in a distributed storage system receiving a transmission request for target data, obtaining a transmission link for transmitting the target data, wherein the transmission request carries priority information of a service type to which the target data belongs.

[0041] In the embodiment of the present disclosure, target data belongs to different service types and has different priorities, and thus the transmission speed of data of different service types can be controlled according to the priorities.

[0042] In some embodiments, Figure 3 As shown, the distributed storage system also includes a client and a metadata server, wherein the client is used to send a transmission request for target data to the first data server; the metadata server stores the correspondence between the storage directory of the business type and the priority information.

[0043] Correspondingly, obtaining the priority information of the business type to which the target data belongs includes: obtaining the priority information of the business type to which the target data belongs from a transmission request for the target data sent from the client via the first data server; the transmission request carries the priority information of the business type to which the target data belongs; wherein the priority information of the business type to which the target data belongs is obtained by the client from the correspondence between the storage directory of the business type stored on the metadata server and the priority information according to the storage directory corresponding to the business type to which the target data belongs.

[0044] Optionally, one business type of data corresponds to one file target. One business type of data may be data corresponding to an application, or data corresponding to a certain type of service in the application (e.g., a chat service). The metadata server may store a mapping relationship between file targets and priorities. Exemplarily, the priority may be represented by an integer between 0 and 10; wherein, the smaller the value of the priority, the higher the corresponding priority.

[0045] Optionally, the mapping relationship may be stored in a configuration table of the metadata server and loaded into the memory when the metadata server is started. The mapping relationship may be stored in a hash table.

[0046] For example, Figure 3 and Figure 4 As shown, the client can obtain the priority information of the business type to which the target data belongs from the metadata server, and when the client sends a transmission request for the target data to the first data server, the transmission request carries the priority information of the business type to which the target data belongs. It should be noted that in the distributed storage system, the client can be a client located in the computer room or a mobile client. Among them, the client can send a transmission request to the first data server.

[0047] In the embodiment of the present disclosure, the transmission request of the target data may be a request to write the target data or a request to read the target data.

[0048] In some embodiments, the transmission request includes a write request, which carries address information of a second data server to which target data is to be written; accordingly, obtaining a transmission link for transmitting the target data includes: obtaining, through the first data server, the address information of the second data server to which the target data is to be written from the write request; creating, through the first data server, a transmission link between the first data server and the second data server according to the address information of the second data server; wherein the transmission link is used by the first data server to write the target data to the second data server.

[0049] For example, Figure 3 As shown, the transmission request may be a write request sent by the client to the first data server. The write request carries the address information of the second data server to which the target data is to be written. The first data server may obtain the address information of the second data server from the write request.

[0050] Optionally, the metadata server may also store a correspondence between identification information of the data server and address information of the data server. Accordingly, obtaining the address information of the second data server to which the target data is to be written through the client includes: determining the identification information of the second data server to which the target data is to be written through the client, and obtaining the address information of the second data server from the address information corresponding to each of the multiple data servers stored in the metadata server according to the identification information.

[0051] In other embodiments, Figure 4 As shown, the distributed storage system also includes a client and a metadata server, wherein the client is used to send a read request for target data to the first data server; the metadata server stores the correspondence between the identification information of the data server and the address information of the data server. When the client sends a read request to the first data server, it is necessary to create a transmission link between the first data server and the client, and read the target data on the first data server through the transmission link.

[0052] Optionally, a transmission link between the first data server and the client may be created through the client, and the corresponding specific steps are: the client determines the identification information of the first data server storing the target data, and obtains the address information of the first data server from the correspondence between the identification information of the data server stored in the metadata server and the address information of the data server according to the identification information. The client creates a transmission link between the first data server and the client according to the address information of the first data server.

[0053] It should be noted that if Figure 4 As shown, the client can also obtain the priority information of the business type to which the target data belongs from the metadata server. The client sends a read request for the target data to the first data server, and the read request can also carry the priority information of the business type to which the target data belongs.

[0054] S202. Configure a first priority parameter for the transmission link according to priority information of the service type to which the target data belongs, through the first data server, wherein the first priority parameter is used to indicate the priority of the transmission link at the transmission layer.

[0055] Optionally, the first priority parameter is an integer of a preset type. Exemplarily, the first priority parameter is a so_mark parameter, and the so_mark parameter is an integer of uint32_t type.

[0056] The network permissions required to configure the first priority parameter are relatively high. An independent priority configuration process may be configured in the first data server. Figure 3As shown, a priority configuration process and a data transmission process are installed on the first data server; accordingly, this step includes: executing the data transmission process through the first data server, transmitting the priority information of the business type to which the target data belongs and the transmission link to the priority configuration process, and configuring the first priority parameter for the transmission link according to the priority information of the business type to which the target data belongs by executing the priority configuration process; wherein the network authority of the priority configuration process is higher than the network authority of the data transmission process. Exemplarily, the priority configuration process is an agent process.

[0057] The priority configuration process can configure the first priority parameter for the transmission link by calling a preset priority configuration function. Accordingly, by executing the priority configuration process, the first priority parameter is configured for the transmission link according to the priority information of the service type to which the target data belongs, including: calling the preset priority configuration function by executing the priority configuration process; configuring the first priority parameter for the transmission link according to the priority information of the service type to which the target data belongs through the preset priority configuration function; wherein the preset priority configuration function is the setsockopt function, and the first priority parameter is the so_mark parameter.

[0058] In the embodiment of the present disclosure, since the network permissions required to configure the so_mark parameter are relatively high, here, the so_mark parameter is configured for the transmission link through an independent priority configuration process (such as an agent process), and a higher permission mode (such as root mode) is configured for the agent process, while the first data server runs in a lower permission mode, which can reduce the probability of the first data server being attacked by the network.

[0059] S203. In response to transmitting the target data through the transmission link, the first data server configures a second priority parameter for the target data according to the first priority parameter of the transmission link, so that the data transmission device allocates network bandwidth to the target data according to the second priority parameter, wherein the second priority parameter is used to indicate the priority of the target data at the network layer, and the data transmission device is located on the transmission link and is used to forward the target data transmitted by the transmission link.

[0060] In the embodiment of the present disclosure, in response to the transmission link successfully configuring the first priority parameter, the target data is transmitted through the transmission link. Exemplarily, the first data server receives a response signal indicating that the transmission link successfully configures the first priority parameter, and transmits the target data through the transmission link.

[0061] The second priority parameter may be a priority of any network layer. Optionally, the second priority parameter is a DSCP (Differentiated Services Code Point) parameter.

[0062] In some embodiments, a second priority parameter can be configured for the target data through a preset configuration rule. Accordingly, this step is: obtaining a preset configuration rule through a first data server, wherein the preset configuration rule is used to convert the first priority parameter into a second priority parameter; converting the first priority parameter of the transmission link into the second priority parameter according to the preset configuration rule through the first data server; and configuring the second priority parameter for the target data through the first data server.

[0063] For example, Figure 3 As shown, the configuration center stores preset configuration rules, and the first data server can obtain the preset configuration rules from the configuration center through an agent process.

[0064] Optionally, the preset configuration rule may be an iptables rule, through which the so_mark value (i.e., the first priority parameter) may be converted into a DSCP value (i.e., the second priority parameter). Exemplarily, the target data is a TCP data packet. When a TCP data packet is transmitted through a transmission link, the iptables rule is used to fill in the corresponding DSCP value of the TCP data packet according to the so_mark value.

[0065] In some embodiments, the data transmission device may allocate corresponding network bandwidth to the target data according to the DSCP parameter. The data transmission device stores the correspondence between the priority parameter and the network bandwidth; accordingly, the data transmission device allocates the network bandwidth to the target data according to the second priority parameter, including: the data transmission device obtains the target network bandwidth corresponding to the second priority parameter from the stored correspondence between the priority parameter and the network bandwidth according to the second priority parameter; the data transmission device allocates the target network bandwidth to the target data.

[0066] It should be noted that if Figure 3 As shown, multiple data servers are located in multiple computer rooms, and at least one data server is deployed in each computer room; the distributed storage system also includes a data transmission device, wherein a data server in one computer room transmits data with a data server in another computer room through the data transmission device. Figure 4As shown, the data server in the computer room can also transmit data to the client through the data transmission device. It should be noted that during the process of writing data to a data server in one computer room, a copy of the data can be stored in a data server in another computer room, so that data transmission between computer rooms exists. During the reading process of a data server in a computer room, if data loss occurs, data transmission for reading across computer rooms may also occur.

[0067] Compared with the network bandwidth within the computer room, the network bandwidth across computer rooms is often tight. During business peaks, the network bandwidth often cannot meet the needs of all businesses. This requires us to distinguish the priority of business traffic, limit the speed of low-priority business data during peak hours, and ensure the network bandwidth of high-priority business data.

[0068] Among them, the data transmission device is located on the transmission link and is used to forward the target data transmitted by the transmission link. For example, in a data writing scenario, the transmission link is used by the first data server to write the target data to the second data server. The data transmission device is located on the transmission link, receives the target data sent by the first data server, and sends the target data to the second data server, thereby realizing the forwarding of the target data transmitted by the transmission link. For another example, in a data reading scenario, the transmission link is used by the client to read the target data from the first data server. The data transmission device is located on the transmission link, receives the target data sent by the first data server, and sends the target data to the client, thereby realizing the forwarding of the target data transmitted by the transmission link.

[0069] Optionally, the data transmission device may be a switch or a network switch. The data transmission device (e.g., a switch) may limit the speed of different data according to the priority parameter of the data. It should be noted that the higher the priority of the second priority parameter, the larger the allocated target network bandwidth and the faster the data transmission speed. It can be seen that the data transmission device may allocate network bandwidth to different service data according to the DSCP value of the service data, i.e., the priority situation, and high-priority services may obtain a larger network bandwidth.

[0070] For example, Figure 3 As shown, after allocating the target network bandwidth to the target data, the first data server can write the target data to the second data server through the transmission link according to the target network bandwidth. Figure 4 As shown, after allocating the target network bandwidth to the target data, the first data server can transmit the target data to the client through the transmission link according to the target network bandwidth.

[0071] The network traffic control method based on the distributed storage system provided in this embodiment is as follows: in response to a first data server in the distributed storage system receiving a transmission request for target data, a transmission link for transmitting the target data is obtained, wherein the transmission request carries the priority information of the service type to which the target data belongs; the first data server configures a first priority parameter for the transmission link according to the priority information of the service type to which the target data belongs, wherein the first priority parameter indicates the priority of the transmission link at the transmission layer; in response to transmitting the target data through the transmission link, the first data server configures a second priority parameter for the target data according to the first priority parameter of the transmission link, so that the data transmission device allocates network bandwidth to the target data according to the second priority parameter, wherein the second priority parameter indicates the priority of the target data at the network layer, wherein the data transmission device is located on the transmission link and is used to forward the target data transmitted by the transmission link. In the embodiment of the present application, since the first priority parameter can be configured for different traffic according to the priority of its own service, when transmitting data, the first priority parameter is converted into the second priority parameter of the network layer, so that the switch can allocate the corresponding network bandwidth to the target data according to the second priority parameter of the network layer, thereby realizing the control of the priority of data transmission according to the service type, realizing more fine-grained traffic priority control, and thus improving the accuracy of controlling traffic bandwidth.
