[0002] In the field of server management, the Intelligent Platform Management Interface (IPMI) has become a standard feature to provide remote monitoring and management capabilities.

[0003] In the related art, when the server has no network, the client uses the ipmitool tool to start the SOL (Serial-over-LAN) function, which allows the client to remotely access the serial interface of the server through the network to achieve communication between the client and the serial port of the server.

[0004] However, due to the exclusivity of the server's serial port, when a client is connected to the server's serial port via SOL, other clients cannot connect to the server's serial port to communicate with the server's serial port, that is, they cannot access the server's serial port in parallel, resulting in low data processing efficiency.

[0095] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0096] In the field of server management, the Intelligent Platform Management Interface (IPMI) has become standard. IPMI is an open standard hardware management interface specification that defines a specific method for embedded management subsystems to communicate. It allows system administrators to manage computer systems through an interface that is independent of the operating system and hardware manufacturers. IPMI provides a standardized method to monitor system health, event logs, power management, temperature, fan speed, voltage and other information, as well as remote control and recovery of the system.

[0097] Figure 1 FIG. 1 is a schematic diagram of establishing a SOL connection in the related art. Figure 1 As shown in the figure, when the server has no network or the system on the server has no IP address configured, the client uses the ipmitool tool to execute the ipmitool command to establish a SOL connection, that is, to start the SOL function. The SOL function is a remote access technology that allows the client to remotely access the serial port (serial port) of the server through a network (LAN) connection, thereby realizing data transmission between the client and the serial port of the server through the network. This function allows administrators to access the console of the server from a remote location, so it is often used for remote diagnosis and troubleshooting. Among them, the ipmitool tool is a command line tool widely used in Linux systems, allowing users to manage and monitor computer hardware through the IPMI standard.

[0098] It should be noted that Figure 1 The terminal in the example is the client. The serial port is usually the ttyS0 serial port. The program that monitors ttyS0 is used to monitor the status of the ttyS0 serial port.

[0099] The client sends and receives data through the LAN, and the server receives and sends data through the serial port. This is the basic way of a SOL connection.

[0100] Normally, a SOL session is exclusive, that is, only one user or client is allowed to connect to the serial console or serial port of the server through SOL at the same time to avoid command conflicts and data confusion.

[0101] However, due to the exclusivity of the server's serial port (i.e., once a program opens the serial port, other programs cannot open the serial port), when a client connects to the server's serial port through SOL, other clients cannot connect to the server's serial port to communicate with the server's serial port, that is, only one SOL connection can be established. If different scenarios require opening an established SOL connection, the established SOL connection must be closed before a new SOL connection can be established and opened, resulting in the client being unable to access the server's serial port in parallel, resulting in low data processing efficiency.

[0102] An embodiment of the present invention provides a data communication method, which establishes a connection between a serial port of a server and a network service end, uses the network service end to receive data transmission requests sent by multiple clients through their corresponding client transmission channels, and uses the connection channel between the serial port of the server and the network service end to send the received data transmission requests of the multiple clients to the serial port of the server, so that the serial port of the server parses the data transmission request to obtain the data to be transmitted and the transmission requirements, determines the target data transmission channel based on the transmission requirements, sends the data to be transmitted to the target data transmission channel, so that the target transmission channel processes the data to be transmitted, and after the processing is completed, sends response information to the serial port, the serial port receives the response information, and sends the response information to the network service end, the network service end parses the response information to obtain the response data, and sends the response data to the corresponding client to achieve the effect of realizing multiple clients to access the serial port of the server in parallel and improving the data processing efficiency.

[0103] According to an embodiment of the present invention, a data communication 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.

[0104] In this embodiment, a data communication method is provided, which can be used for the serial port of the server. Figure 2 is a flow chart of a data communication method according to an embodiment of the present invention. Figure 2As shown, the process includes the following steps:

[0105] Step S201, establishing a connection with a network server.

[0106] Among them, the network server is the socket server.

[0107] The server is a bare metal node, a node without a network. The server's serial port establishes a SOL connection with the network server, and data communication can be carried out with the network server through LAN.

[0108] Step S202, receiving a data transmission request sent by the network server, wherein the network server receives the data transmission requests sent by multiple clients through their corresponding client transmission channels, and sends the data transmission requests to the serial port of the server.

[0109] in, Figure 3 Schematic diagram of the structure of data communication according to an embodiment of the present invention. Figure 3 As shown, the network server can be accessed by multiple clients, and the multiple clients communicate data with the serial port of the server through the connection channel between the network server and the serial port of the server.

[0110] The client transmission channel may be a virtual device, a virtual socket connection, or an input / output file or other form that can realize input / output functions.

[0111] Multiple clients send data transmission requests for the serial port of the server to the network service end, and the network service end sends the data transmission request to the serial port of the server through a connection channel with the serial port of the server.

[0112] Step S203: parse the data transmission request to obtain the data to be transmitted and the transmission requirements.

[0113] After receiving the data transmission request sent by the network service end, the serial port of the server parses the data transmission request to obtain the data to be transmitted and the transmission requirements in the data transmission request. The serial port of the server is the ttyS0 serial port.

[0114] Step S204: determining a target data transmission channel based on the transmission requirement.

[0115] After the transmission requirement is obtained, a target data transmission channel is determined according to the transmission requirement.

[0116] It should be noted that the data transmission channel can be a virtual serial port, a virtual device, a virtual connection, or an input and output file, etc. Figure 3 As shown, the serial port of the server corresponds to multiple data transmission channels, among which, Figure 3 In the example, a data transmission channel is a virtual serial port. According to the transmission requirements, a target data transmission channel among multiple data transmission channels is determined.

[0117] Each data transmission channel corresponds to a program for monitoring the data transmission channel, and the program for monitoring the data transmission channel is used to monitor the data transmission channel.

[0118] Step S205, sending the data to be transmitted to the target data transmission channel, so that the target data transmission channel processes the data to be transmitted, and after the processing is completed, sends response information to the serial port.

[0119] The program monitoring the target data transmission channel sends a response message to the target data transmission channel after monitoring that the processing of the data to be transmitted is completed, and the target data transmission channel sends the response message to the serial port of the server.

[0120] Step S206, receiving the response information, and sending the response information to the network server, so that the network server receives the response information, parses the response information, obtains response data, and sends the response data to the corresponding client.

[0121] The network server sends the response data in the response information to the client that sends the data transmission request corresponding to the response data, thereby realizing data communication between the serial port of the client and the server.

[0122] The data communication method provided in this embodiment establishes a connection between the serial port of the server and the network service end, uses the network service end to receive data transmission requests sent by multiple clients through their corresponding client transmission channels, uses the connection channel between the serial port of the server and the network service end to send the received data transmission requests of multiple clients to the serial port of the server, so that the serial port of the server parses the data transmission request, obtains the data to be transmitted and the transmission requirements, determines the target data transmission channel based on the transmission requirements, sends the data to be transmitted to the target data transmission channel, so that the target transmission channel processes the data to be transmitted, and after the processing is completed, sends a response message to the serial port, the serial port receives the response message, sends the response message to the network service end, and the network service end parses the response message to obtain the response data, and sends the response data to the corresponding client. By using the only channel between the network service end and the serial port of the server to realize the data transmission of multiple clients, the parallel access to the serial port of the server is realized, and the data processing efficiency is improved.

[0123] The data communication method provided in this embodiment, by adding virtual devices or connections, multiple virtual devices and connections transmit data with the serial port of the server through the SOL connection between the network service end and the serial port of the server, thereby realizing expansion on one SOL connection, expanding one SOL connection into multiple communication connections, and maintaining the original SOL function, the effect of communication between multiple clients and the serial port of the server can be carried out at the same time. For example, when a terminal console is opened on a bare metal node (the original function can only open one terminal console), a new terminal console is opened, and the two terminal consoles do not affect each other. On the basis of opening other functions, other applications can be run, such as transferring files, changing passwords, changing configurations, and querying logs.

[0124] In this embodiment, a data communication method is provided, which can be used for the serial port of the server. Figure 4 is a flow chart of a data communication method according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0125] Step S401: Establish a connection with the network server. Figure 2 Step S201 of the illustrated embodiment will not be described in detail here.

[0126] Step S402, receiving a data transmission request sent by the network server, wherein the network server receives data transmission requests sent by multiple clients through their corresponding client transmission channels, and sends the data transmission requests to the serial port of the server. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0127] Step S403: parse the data transmission request to obtain the data to be transmitted and the transmission requirements.

[0128] Specifically, the above step S403 includes:

[0129] Step S4031, parsing the data transmission request to obtain the target client transmission channel identifier, the data to be transmitted and the transmission requirements.

[0130] Among them, multiple data transmission requests need to achieve data isolation, otherwise the data transmitted on the same SOL connection will be confused. In this embodiment, each client transmission channel is assigned a unique client transmission channel identifier (ID), and each client and the network server perform data transmission through a unique client transmission channel.

[0131] After receiving the data transmission request sent by the client, the network server encapsulates the client transmission channel identifier corresponding to the client into the data transmission request, and then sends the data transmission request to the serial port of the server. In this way, the serial port of the server can know which client the data transmission request comes from, thereby realizing data isolation.

[0132] Figure 5 FIG. 1 is a schematic diagram of a data transmission request according to an embodiment of the present invention. Figure 5 As shown, the data transmission request may include a channel ID, that is, a client transmission channel identifier, and the channel data, that is, data to be transmitted. The transmission requirements are not shown in the figure.

[0133] Step S404: determine a target data transmission channel based on the transmission requirement.

[0134] Specifically, the above step S404 includes:

[0135] Step S4041: When the transmission requirement is to transfer the data to be transmitted to a new data transmission channel, a target data transmission channel is created based on the type of data to be transmitted in the transmission requirement.

[0136] The data transmission request is parsed to obtain the data to be transmitted, the transmission requirement and the target client transmission channel identifier. If the transmission requirement is to transfer the data to be transmitted to a new data transmission channel, a target data transmission channel is created according to the type of data to be transmitted in the transmission requirement, and a corresponding target data transmission channel identifier is allocated to the target data transmission channel.

[0137] It can be understood that, if the transmission requirement is to transmit the data to be transmitted to an existing data transmission channel, the target data transmission channel is determined according to the target data transmission channel identifier in the transmission requirement.

[0138] It should be noted that the transmission requirement may be to transfer the data to be transmitted to multiple new data transmission channels, and then multiple target data transmission channels are created according to the multiple types of data to be transmitted in the transmission requirement.

[0139] The transmission requirement may also be to transmit the data to be transmitted to multiple existing data transmission channels, and then multiple target data transmission channels are determined according to multiple target data transmission channel identifiers in the transmission requirement.

[0140] The transmission requirement may also be to transmit the data to be transmitted to several new data transmission channels and several existing data transmission channels. Then, the corresponding target data transmission channel is determined according to several target data transmission channel identifiers in the transmission requirement and several target data transmission channels created according to several types of data to be transmitted in the transmission requirement.

[0141] Step S405, sending the data to be transmitted to the target data transmission channel, so that the target data transmission channel processes the data to be transmitted, and after the processing is completed, sends a response message to the serial port. Figure 2 Step S205 of the illustrated embodiment will not be described in detail here.

[0142] Step S406: Receive the response information and send the response information to the network server, so that the network server receives the response information, parses the response information, obtains the response data, and sends the response data to the corresponding client. Figure 2 Step S206 of the illustrated embodiment will not be described in detail here.

[0143] The data communication method provided in this embodiment can ensure that the response data is accurately sent to the specified client by obtaining the target client transmission channel identifier in the data transmission request, thereby avoiding data transmission errors. By adding the target client transmission channel identifier in the data transmission request to control the accurate link of the data transmission, the isolation of multi-channel data is achieved.

[0144] The data communication method provided in this embodiment can meet the needs of data transmission requests sent by multiple clients by creating a target data channel according to the transmission requirements and the type of data to be transmitted, so that multiple clients can transmit data through the channel between the network service end and the serial port of the server, thereby improving data processing efficiency.

[0145] In some optional implementations, each data transmission channel corresponds to a unique data transmission channel identifier, and before sending the data to be transmitted to the target data transmission channel, the data communication method further includes:

[0146] Step a1, sending the correspondence between the target client transmission channel identifier and the target data transmission channel identifier corresponding to the target data transmission channel to the network server, so that the network server updates the preset channel correspondence table based on the correspondence between the target client transmission channel identifier and the target data transmission channel identifier, and after receiving the response information, parsing the response information to obtain the response data and the target data transmission channel identifier, based on the preset channel correspondence table, determining the target client transmission channel identifier corresponding to the target data transmission channel identifier, and based on the target client transmission channel identifier, sending the response data to the corresponding client.

[0147] The preset channel correspondence table is initially empty. The network client updates the preset channel correspondence table based on the correspondence between the target client transmission channel identifier and the target data transmission channel identifier, including:

[0148] If the preset channel correspondence table does not contain the target client transmission channel identifier and the target data transmission channel identifier, the correspondence between the target client transmission channel identifier and the target data transmission channel identifier is added to the preset channel correspondence table.

[0149] If the target client transmission channel identifier exists in the preset channel correspondence table, the existing correspondence of the target client transmission channel identifier in the preset channel correspondence table is updated to the correspondence between the target client transmission channel identifier and the target data transmission channel identifier.

[0150] If the target data transmission channel identifier exists in the preset channel correspondence table, the existing correspondence of the target data transmission channel identifier in the preset channel correspondence table is updated to the correspondence between the target client transmission channel identifier and the target data transmission channel identifier.

[0151] In order to make the data communication method provided by this embodiment clearer, it is described in conjunction with a specific example.

[0152] Figure 6 FIG. 1 is a flow chart of data communication according to an embodiment of the present invention. Figure 6As shown, 1. The access client, i.e., terminal A, on the network server sends the data "hello" through its corresponding client transmission channel. It should be noted that a transmission requirement is also sent at the same time, which is not shown here. The client transmission channel corresponding to the client transmission channel is identified as 100001. 2. The network server encapsulates the data "hello" sent by the client as "100001+hello". 3. The network server sends "100001+hello" to the serial port ttyS0 of the server through the LAN. 4. After receiving "100001+hello", the serial port ttyS0 of the server unpacks it and obtains "hello". According to the transmission requirement, the target data transmission channel is determined to be virtual serial port 1, wherein the data transmission channel identification of virtual serial port 1 is 200001. 5. The serial port ttyS0 of the server sends "hello" to virtual serial port 1. After receiving "hello", virtual serial port 1 processes it. After the program that monitors virtual serial port 1 completes the processing of virtual serial port 1, it sends the response message "welcome" to virtual serial port 1 as the program's response to "hello". 6. Virtual serial port 1 encapsulates "welcome" as "200001+welcome" and sends the encapsulated data to serial port ttyS0. 7. Serial port ttyS0 sends "200001+welcome" to the network server through LAN. 8. The network server receives "200001+welcome", decapsulates it, obtains "welcome", and determines that the client transmission channel identifier is 100001 according to the preset channel correspondence table and 200001. 9. The network server determines the target client transmission channel according to the client transmission channel identifier 100001, and sends "welcome" to terminal A through the target client transmission channel to achieve data communication.

[0153] The data communication method provided in this embodiment maintains and updates the preset channel correspondence table, parses the response information and determines the target client transmission channel identifier based on the preset channel correspondence table, so that the response data can be sent to the corresponding client quickly and accurately, thereby improving processing efficiency and avoiding data transmission errors.

[0154] In some optional implementations, the data communication method further includes:

[0155] Step b1: if multiple data transmission requests sent by the network server are received at the same time, the multiple data transmission requests are processed and sorted.

[0156] Among them, since multiple clients correspond to one SOL connection in this embodiment, the network server may receive multiple data transmission requests simultaneously. If the network server sends the multiple received data transmission requests to the serial port of the server at the same time, it will cause the serial port of the server to be unable to process the data transmission requests orderly, resulting in data chaos.

[0157] In this embodiment, when the serial port of the server receives multiple data transmission requests sent by the network server at the same time, the multiple data transmission requests are sorted for processing, and the multiple data transmission requests are cached.

[0158] Step b2: Process the multiple data transmission requests in sequence according to the result of the processing sorting.

[0159] After sorting the processing of the multiple data transmission requests, according to the result of the sorted processing, the multiple data transmission requests are processed in order.

[0160] The data communication method provided by this embodiment, by sorting the processing of the data transmission requests when receiving multiple data transmission requests sent by the network server at the same time, so as to process the multiple data transmission requests in sequence, in case of data transmission chaos, resulting in data transmission errors.

[0161] In some alternative embodiments, step b1 above includes:

[0162] Step b11: Obtain the client transmission channel identifiers corresponding to the multiple data transmission requests.

[0163] Among them, the multiple data transmission requests are parsed to obtain the client transmission channel identifiers in each data transmission request.

[0164] Step b12: Sort the processing of the multiple data transmission requests based on the order of the client transmission channel identifiers.

[0165] When the client transmission channel identifiers in the multiple data transmission requests are obtained, the processing of the multiple data transmission requests is sorted according to the order of the client transmission channel identifiers.

[0166] It should be noted that the technical personnel assign corresponding client transmission channel identifiers to each client transmission channel and set the sequence of the client transmission channel identifiers.

[0167] The data communication method provided by this embodiment, by obtaining the client transmission channel identifiers corresponding to the multiple data transmission requests and sorting the processing of the multiple data transmission requests according to the order of the client transmission channel identifiers, to ensure the orderly processing of the data transmission requests and avoid data transmission chaos.

[0168] In this embodiment, a data communication method is provided, which can be used in a network service end. Figure 7 is a flow chart of a data communication method according to an embodiment of the present invention. Figure 7 As shown, the process includes the following steps:

[0169] Step S701: Establish a connection with a serial port of a server.

[0170] Step S702: receiving data transmission requests sent by multiple clients through their corresponding client transmission channels.

[0171] Step S703, sending a data transmission request to the serial port of the server so that the serial port receives the data transmission request, parses the data transmission request, obtains the data to be transmitted and the transmission requirements, determines the target data transmission channel based on the transmission requirements, sends the data to be transmitted to the target data transmission channel, the target data transmission channel processes the data to be transmitted, and after the processing is completed, sends a response message to the serial port, the serial port receives the response message, and sends the response message to the network server.

[0172] Step S704, receiving response information, parsing the response information, and obtaining response data.

[0173] Step S705: sending the response data to the corresponding client.

[0174] The detailed description of each step of the data communication method is as follows Figure 2 The detailed description of the corresponding steps in the embodiment is the same and will not be repeated here.

[0175] The data communication method provided in this embodiment establishes a connection between the serial port of the server and the network service end, uses the network service end to receive data transmission requests sent by multiple clients through their corresponding client transmission channels, uses the connection channel between the serial port of the server and the network service end to send the received data transmission requests of multiple clients to the serial port of the server, so that the serial port of the server parses the data transmission request, obtains the data to be transmitted and the transmission requirements, determines the target data transmission channel based on the transmission requirements, sends the data to be transmitted to the target data transmission channel, so that the target transmission channel processes the data to be transmitted, and after the processing is completed, sends a response message to the serial port, the serial port receives the response message, sends the response message to the network service end, and the network service end parses the response message to obtain the response data, and sends the response data to the corresponding client. By using the only channel between the network service end and the serial port of the server to realize the data transmission of multiple clients, the parallel access to the serial port of the server is realized, and the data processing efficiency is improved.

[0176] In this embodiment, a data communication method is provided, which can be used in a network service end. Figure 8 is a flow chart of a data communication method according to an embodiment of the present invention. Figure 8 As shown, the process includes the following steps:

[0177] Step S801: Establish a connection with a serial port of a server.

[0178] Specifically, the above step S801 includes:

[0179] Step S8011: determining a connection command based on the address information of the baseboard management controller of the server.

[0180] Wherein, establishing a connection between the network service end and the serial port of the server is essentially establishing a connection between the network service end and the baseboard management controller, and establishing a connection between the baseboard management controller and the serial port of the server.

[0181] Taking establishing a connection between a network service end and a serial port of any server as an example, illustratively, the address information of the baseboard management controller of the server is 10.10.10.10, and the connection command is determined to be ipmitool –I lanplus –H10.10.10.10 –L ADMINISTRATOR –U user –U password sol active.

[0182] Step S8012, running a connection command to establish a connection between the network server and the baseboard management controller, and the baseboard management controller is connected to the serial port of the server.

[0183] Among them, a connection command is run on the machine where the network server is located to establish a connection between the network server and the baseboard management controller, and the baseboard management controller is connected to the serial port of the server, thereby realizing the connection between the network server and the serial port of the server.

[0184] Step S802: Receive data transmission requests sent by multiple clients through their corresponding client transmission channels. Figure 7 Step S702 of the illustrated embodiment will not be described in detail here.

[0185] Step S803, sending a data transmission request to the serial port of the server so that the serial port receives the data transmission request, parses the data transmission request, obtains the data to be transmitted and the transmission requirements, determines the target data transmission channel based on the transmission requirements, sends the data to be transmitted to the target data transmission channel, the target data transmission channel processes the data to be transmitted, and after the processing is completed, sends a response message to the serial port, the serial port receives the response message, and sends the response message to the network server.

[0186] Specifically, the above step S803 includes:

[0187] Step S8031: for any data transmission request, parse the data transmission request to obtain the transmission requirement.

[0188] The network service end can establish connections with serial ports of multiple servers. In order to determine the serial port of the target server to which the data transmission request is to be transmitted, the data transmission request needs to be parsed to obtain the transmission requirement.

[0189] Fig. 9 FIG. 1 is a schematic diagram of establishing a connection between a network service end and serial ports of different servers according to an embodiment of the present invention. Fig. 9 As shown, the network service end establishes a SOL connection with the serial port of one of the servers, and the data transmission requests issued by the three clients connected to the network service end can communicate data through the three data transmission channels corresponding to the serial port ttyS0 of the server through the LAN. Among them, the client transmission channel identifiers corresponding to the client transmission channels corresponding to the three clients are A-1-1, A-1-2, and A-1-3 respectively, and the data transmission channel identifiers corresponding to the three data transmission channels are S-1-1, S-1-2, and S-1-3 respectively.

[0190] The network service end establishes a SOL connection with the serial port of another server, and the data transmission requests issued by the three clients connected to the network service end can communicate data through the three data transmission channels corresponding to the serial port ttyS0 of the server through the LAN. The client transmission channel identifiers corresponding to the client transmission channels corresponding to the three clients are A-2-1, A-2-2, and A-2-3, respectively, and the data transmission channel identifiers corresponding to the three data transmission channels are S-2-1, S-2-2, and S-2-3, respectively.

[0191] In this case, the client in one SOL connection corresponding to the network server cannot communicate with the data channel in another SOL connection.

[0192] To solve this problem, the embodiment of the present invention connects data between different SOL connections of the network server. Fig.10Schematic diagram of establishing connection between a network service end and serial ports of different servers according to an embodiment of the present invention, such as Fig.10 As shown, the embodiment of the present invention realizes data connectivity by forwarding different SOL connections of the network service end through multiple SOL connections.

[0193] When the data transmission request of channel A1-1-1 needs to be sent to channel S-2-1, the data transmission request of channel A1-1-1 is forwarded to the SOL2 connection through the multi-SOL connection forwarding in the network server, that is, the data transmission request of channel A1-1-1 can be sent to channel S-2-1 through the SOL2 connection. The response information of channel S-2-1, after being transmitted through the SOL2 connection, also needs to be forwarded to channel A1-1-1.

[0194] It should be noted that to achieve cross-SOL connection communication, it is necessary to ensure that the client transmission channel identifier and the data transmission channel identifier are globally unique.

[0195] Step S8032, determining the serial port of the target server according to the transmission requirements.

[0196] After the transmission request is obtained, the serial port of the target server in the transmission request is obtained, that is, the serial port to which the data transmission request is to be transmitted.

[0197] Step S8033, sending a data transmission request to the serial port of the target server so that the serial port of the target server receives the data transmission request, parses the data transmission request, obtains the data to be transmitted and the transmission requirements, determines the target data transmission channel based on the transmission requirements, sends the data to be transmitted to the target data transmission channel, the target data transmission channel processes the data to be transmitted, and after the processing is completed, sends a response message to the serial port, the serial port receives the response message, and sends the response message to the network server.

[0198] After the serial port to which the data transmission request is to be transmitted is known, the data transmission request is sent to the serial port of the corresponding target server.

[0199] Step S804: Receive response information, parse the response information, and obtain response data. Figure 7 Step S704 of the illustrated embodiment will not be described in detail here.

[0200] Step S805: Send the response data to the corresponding client. Figure 7 Step S705 of the illustrated embodiment will not be described in detail here.

[0201] The data communication method provided in this embodiment establishes a connection between a network server and a baseboard management controller, which is connected to a serial port of a server, and then establishes a connection between the network server and the serial port of the server, thereby realizing data communication between multiple clients connected to the network server and the serial port of the server.

[0202] The data communication method provided in this embodiment can connect through a node that can establish an SOL connection when a certain node cannot establish an SOL connection. For example, a command can be executed on a terminal that cannot establish an SOL connection, and then communication can be carried out through other nodes that can establish an SOL connection.

[0203] In some optional implementations, the data communication method further includes:

[0204] Step c1: if multiple data transmission requests sent by multiple clients are received at the same time, the multiple data transmission requests are sorted for sending.

[0205] Among them, since multiple clients correspond to one SO1 connection in this embodiment, the network server may receive multiple data transmission requests sent by multiple clients at the same time. In this case, if the multiple data transmission requests are sent to the corresponding server's port serial port, data confusion may occur. Therefore, when the network server receives multiple data transmission requests sent by multiple clients at the same time, it sorts the multiple data transmission requests and caches the data transmission requests.

[0206] Step c2: sending multiple data transmission requests to the serial port of the server in sequence according to the result of the sending sorting.

[0207] After the multiple data transmission requests are sorted for transmission, the multiple data transmission requests are sequentially sent to the serial ports of the corresponding servers according to the result of the sending sorting.

[0208] The data communication method provided in this embodiment, when receiving multiple data transmission requests sent by multiple clients at the same time, sorts the data transmission requests so as to send the multiple data transmission requests in sequence, so as to prevent data transmission confusion and data transmission errors.

[0209] In some optional implementations, the above step c1 includes:

[0210] Step c11: obtaining client transmission channel identifiers corresponding to multiple data transmission requests.

[0211] The multiple data transmission requests are parsed to obtain the client transmission channel identifier in each data transmission request.

[0212] Step c12: sorting the multiple data transmission requests based on the order of the client transmission channel identifiers.

[0213] When the client transmission channel identifiers in the multiple data transmission requests are obtained, the multiple data transmission requests are sorted for sending according to the order of the client transmission channel identifiers.

[0214] The data communication method provided in this embodiment obtains the client transmission channel identifiers corresponding to multiple data transmission requests, and sorts the multiple data transmission requests in the order of the client transmission channel identifiers to ensure the orderly sending of the data transmission requests and avoid data transmission confusion.

[0215] In some optional implementations, the above step S804 includes:

[0216] Step d1, parse the response information to obtain the response data and the target data transmission channel identifier.

[0217] Each data transmission channel corresponds to a unique data transmission channel identifier. After receiving the response information, the serial port of the server encapsulates the target data transmission channel identifier of the target data transmission channel corresponding to the response information in the response information, and then sends the response information to the network service end.

[0218] The network server parses the response information, obtains the response data and the target data transmission channel identifier, and then determines the corresponding target client transmission channel identifier based on the target data transmission channel identifier, and then determines the target client, and sends the response data to the target client.

[0219] The data communication method provided in this embodiment obtains the target data transmission channel identifier in the response information, and then determines the corresponding target client transmission channel identifier, thereby ensuring that the response data can be accurately sent to the specified client and avoiding data transmission errors.

[0220] In some optional implementations, the above step S805 includes:

[0221] Step e1: receiving a correspondence between a target client transmission channel identifier and a target data transmission channel identifier.

[0222] Step e2: updating the preset channel correspondence table based on the correspondence between the target client transmission channel identifier and the target data transmission channel identifier.

[0223] Step e3: determining the target client transmission channel identifier corresponding to the target data transmission channel identifier based on the preset channel correspondence table.

[0224] After the target data transmission channel identifier is obtained, the target client transmission channel identifier corresponding to the target data transmission channel identifier is determined according to a preset channel correspondence table.

[0225] Step e4: based on the target client transmission channel identifier, send the response data to the corresponding client.

[0226] Among them, the server's serial port parses the data transmission request, obtains the target client transmission channel identifier, the data to be transmitted and the transmission requirements, and sends the correspondence between the target client transmission channel identifier and the target data transmission channel identifier corresponding to the target data transmission channel to the network service end.

[0227] After the target client transmission channel identifier is determined, that is, the target client transmission channel is determined, the response data is sent to the corresponding client, that is, the target client, through the target client transmission channel to achieve communication between the serial ports of the client and the server.

[0228] It is understandable that, with respect to the data communication method provided in this embodiment, relevant technical standards and communication protocols for data transmission may be formulated so as to carry out technical development and expansion on this basis.

[0229] The data communication method provided in this embodiment maintains and updates the preset channel correspondence table, parses the response information and determines the target client transmission channel identifier based on the preset channel correspondence table, so that the response data can be sent to the corresponding client quickly and accurately, thereby improving processing efficiency and avoiding data transmission errors.
