[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] The terms "including" and "having" in the specification of the present invention and the above-mentioned drawings, as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may include steps or units that are not listed.

[0057] Some of the terms that appear in the description of the embodiments of the present invention may be interpreted as follows:

[0058] IPMI (Intelligent Platform Management Interface) is an open standard that allows system administrators to manage computer systems through an interface that is independent of the operating system and hardware manufacturer. 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.

[0059] BMC (Baseboard Management Controller) is an embedded management microcontroller used to monitor and manage the physical environment of the server. It is usually integrated on the server's motherboard, but can also exist as an independent hardware component. The main functions of BMC include monitoring the hardware status of the server (such as power supply, fan, temperature sensor, etc.), providing remote management interfaces (such as IPMI, Intelligent Platform Management Interface, Intelligent Platform Management Interface), logging, and system recovery.

[0060] ipmitool is a widely used command line tool in Linux systems that allows users to manage and monitor computer hardware through the IPMI standard. IPMI is an open standard hardware management interface specification that defines a specific method for embedded management subsystems to communicate.

[0061] SOL (Serial-over-LAN) is a remote access technology that allows users to remotely access the serial port of a server through a network (LAN) connection. This technology is often used for remote diagnosis and troubleshooting because it allows administrators to access the console of a server from a remote location.

[0062] Monitoring: The monitoring in this article refers to other general monitoring software, such as telegraf.

[0063] Monitoring server: The monitoring server in this article refers to the server that needs to send the data collected by the monitoring software. This server is the monitoring server. This monitoring server is responsible for collecting data from the monitoring software on multiple machines.

[0064] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0065] Next, a flowchart of a data transmission method applied to a first forwarding node provided by an embodiment of the present invention is described in detail. Figure 1A data transmission method applied to a first forwarding node provided in an embodiment of the present invention may include:

[0066] S101, receiving target data sent by the client.

[0067] The execution subject of this embodiment is the first forwarding node. The address of the network server created by the first forwarding node in this embodiment is consistent with the address of the client, and a connection is established between the client and the network server. If a client establishes a connection with the network server of the first forwarding node, the network server can communicate data with the client, and the first forwarding node forwards the received data sent by the client by writing it into the serial port. This embodiment does not limit the specific client. For example, the client in this embodiment can be monitoring software, or the client in this embodiment can also be remote control software, which allows users to remotely control another computer through the Internet or a local area network to perform file transfer, screen sharing and remote operation, etc.; or the client in this embodiment can also be network management software, which is used to monitor changes in website content to ensure the normal operation of the website and the accuracy of data. This type of software usually needs to communicate with the server to obtain web page content and update status. This embodiment does not limit specific target data. For example, the target data in this embodiment can be monitoring data; or the target data in this embodiment can be communication data.

[0068] It should be further explained that before receiving the target data sent by the client, the following may also be included:

[0069] Determine whether the network between the client and the server is connected; when the network between the client and the server is not connected, determine to execute the step of receiving the target data sent by the client. This embodiment will only execute the step of receiving the target data sent by the client when the client and the server are not connected, and when the network between the client and the server is connected, the target data can be directly transmitted based on the network without being transmitted based on the data transmission method provided by the present invention. The embodiment of the present invention determines the network connectivity of the corresponding server and the client, so that the transmission method of the target data can be determined based on the connectivity result, thereby improving the accuracy of the target data transmission.

[0070] It should be further explained that when the client is monitoring software and the server is a monitoring server, before receiving the target data sent by the client, it can also include: connecting with the first end of the serial port redirection component; wherein the first end of the serial port redirection component is the serial port side; determining that the second forwarding node is connected to the second end of the serial port redirection component; wherein the second end of the serial port redirection component is the local area network side. The serial port side in this embodiment is Serial, and the local area network side in this embodiment is LAN side. For ease of understanding, please refer to Figure 2, Figure 2 A schematic diagram of a first forwarding node connection relationship provided by an embodiment of the present invention, from Figure 2 It can be seen that the first forwarding node creates a TCP network server (address is 127.0.0.1) and allows tcp-client (that is, the monitoring software to establish a connection). If a monitoring software tcp-client establishes a connection with the TCP-server of forwarding node B, the TCP-server can communicate data with the TCP-client, and node B forwards the data sent by the monitoring software tcp-client to B's tcp-server (the part with number 1) by writing it to the serial port (the part with number 2). The first forwarding node will continuously read the serial port to see if there is any data coming in (the part with number 3), that is, serial port reading. The data read is the data sent from the LAN side, and then the read data is sent to the tcp-client of the monitoring software (the part with number 4) through the tcp-server. For ease of understanding, please refer to Figure 3 , Figure 3 A schematic diagram of a second forwarding node connection relationship provided by an embodiment of the present invention, from Figure 3 It can be seen that the second forwarding node establishes a SOL connection through tools or commands related to the BMC-SOL function, and then uses input and output to take over the connection. Input is equivalent to sending data to the serial port through SOL (part of number 5). Output is equivalent to being able to read data sent from the serial port (part of number 6). The second forwarding node establishes a tcp-client and a monitoring server connection (numbers 9 and 10). If the output reads data, that is, data is sent from the serial port, it is equivalent to the monitoring software client sending data. The second forwarding node sends the output data to the tcp-server of the monitoring server through the tcp-client of the second forwarding node (part of number 7). If the tcp-client of the second forwarding node has data sent from the monitoring server, node A forwards the data to the input, and the data can be sent to the serial port (part of number 8). This embodiment enables the entire technical solution to be implemented by providing a specific connection relationship between the first forwarding node and the second forwarding node, thereby improving the accuracy of the data communication link connection.

[0071] It should be further explained that, based on the above embodiment, the sending of the target data to the serial port redirection component may include:

[0072] S1, determine the encoding method and decoding method corresponding to the target data currently being transmitted, and send the encoding method and decoding method to the first end and the second end of the serial port redirection component respectively; wherein the encoding method is an encoding method that ensures that the characters in the data will not change during the transmission process, and the decoding method is a decoding method corresponding to the encoding method.

[0073] The encoding method in this embodiment is such that the target data does not change during the process of sending the target data from the first end of the SOL to the second end of the SOL.

[0074] S2, using the first end of the serial port redirection component, encoding the currently transmitted target data based on the encoding method to obtain target encoded data.

[0075] S3, using the first end of the serial port redirection component to send the target encoded data to the second end of the serial port redirection component, and decoding the target encoded data based on the second end of the serial port redirection component using a decoding method to obtain target decoded data sent to the second forwarding node.

[0076] The target data in this embodiment is the same as the target decoded data.

[0077] Accordingly, using the serial port redirection component to send the target data to the second forwarding node may include:

[0078] S4, using the second end of the serial port redirection component to send the target decoded data to the second forwarding node.

[0079] This embodiment adjusts the characters of the target data through the set encoding mode and decoding mode to prevent the characters from changing during the transmission process, thereby preventing the transmitted target data from being inaccurate.

[0080] It should be further explained that, based on the above embodiment, using the first end of the serial port redirection component to encode the currently transmitted target data based on the encoding method to obtain the target encoded data may include:

[0081] When the encoding method is hexadecimal encoding, the first end of the serial port redirection component is used to determine that the target data currently being transmitted is represented by one byte and changed to two bytes; when the encoding method is special character replacement encoding, the first end of the serial port redirection component is used to determine the characters that will change after transmission from the target data currently being transmitted, and replace the characters that will change with set characters; wherein the set characters are data that will not change after transmission. For example, the hexadecimal encoding in this embodiment refers to changing the data from one byte to two bytes. The content of the data is re-encoded before the SOL connection is transmitted, and the data is decoded after being transmitted to the other end. For example, a byte (8bit), the first 4 bits and the last 4 bits are represented by one byte respectively. For example: the byte value of the character "0" is represented in hexadecimal as: 0X30, 3 is the hexadecimal value of the first 4 bits, and 0 is the value of the last 4 bits. After encoding, the two characters "30" represent the "0" of the original data. The decoding process is the opposite of the encoding process. This embodiment does not limit specific special characters. For example, the special characters in this embodiment are characters that will not change. For example, the special characters in this embodiment may be A, or the special characters in this embodiment may also be B. This embodiment does not limit how to determine the characters that will change after transmission. For example, this embodiment may obtain a list of multiple characters that will change after multiple experiments. When determining the characters that will change, they may be determined directly according to the list; or this embodiment may also determine all characters that may change by transmitting data to SOL. The special character replacement encoding in this embodiment refers to replacing the characters that will change in the data after SOL transmission with character A, and then sending the information of the replacement characters (including content and position) to the opposite end after the transmission is completed, and the opposite end decodes the received data. Replace special data in the data, for example, "0" will change after SOL transmission, all "0" in the original data are replaced with "A", "A" will not change after transmission, record the position of the data "0", and after the data is transmitted, transmit a corrected content. For example, when transmitting data "0123455678", "0" is replaced by "A", and the transmitted data becomes "A12345678". After the transmission, a correction data "[position] [original data]" is transmitted. For example, the correction data "1, 1" is transmitted, indicating that the first character belongs to the first case of replacement (that is, 0 is replaced by A), and then the first character is restored to 0. This embodiment prevents the characters from changing and affecting the accuracy of the transmitted data by encoding and decoding the characters.

[0082] It should be further explained that, based on the above embodiment, in order to improve the accuracy of target data transmission, when the target data is sent to the second forwarding node using the serial port redirection component, it can include: encrypting the target data using a data encryption method to obtain encrypted data, and caching the target data at the same time; when the second end of the serial port redirection component decrypts the encrypted data to obtain the decrypted target data, the decrypted target data is verified, and when it is determined that the target data has not changed, the cached target data is deleted, otherwise it is determined that the target data is encoded before transmission. The embodiment of the present invention ensures the accuracy of target data transmission based on encryption, decryption and verification.

[0083] S102, sending target data to a serial port redirection component; wherein the serial port redirection component is a component that implements a virtual serial port on a baseboard management controller, and the serial port redirection component establishes a connection with the first forwarding node through the serial port.

[0084] The serial port redirection component in this embodiment is SOL (Serial-over-LAN), which is a remote access technology that allows users to remotely access the serial port of the server through a network (LAN) connection. This technology is often used for remote diagnosis and troubleshooting because it allows administrators to access the server console from a remote location. It is to redirect the serial controller of the BMC during the IPMI (Intelligent Platform Management Interface) connection phase. A communication link based on the BMC-SOL function can be established through the ipmitool (command line tool) command. One end of this link is a UDP (User Datagram Protocol) connection and the other end is a serial port. After this link is established, data transmission can be carried out. In the following text, the SOL connection is directly used to represent this link. The two ends of SOL include the LAN (network) side and the Serial (serial port) side. The first forwarding node in this embodiment is connected to the serial port side of SOL.

[0085] S103, using the serial port redirection component to send the target data to the second forwarding node, so that the second forwarding node sends the target data to the server; wherein the first forwarding node is a node connected to the client, and the second forwarding node is a node connected to the server.

[0086] In this embodiment, the second forwarding node is connected to the server, the second forwarding node is connected to the network side of the SOL, and the second forwarding node establishes a tcp-client (transmission control protocol client) connection with the monitoring server.

[0087] It should be further explained that in order to improve communication efficiency, during the above-mentioned target data transmission process, it can also include: sending a heartbeat packet to the second forwarding node in a set time period; if the heartbeat response packet of the second forwarding node is not received within the preset time, determining to resend the heartbeat packet based on the set number of retries, after reaching the number of retries, determining that the heartbeat response packet is not received, and determining that the current data communication link is not connected. In this embodiment, during the process, real-time monitoring is performed on whether the data communication link composed of the client, the first forwarding node, the SOL, the second forwarding node and the server is connected. When it is not connected, it will be processed in time to prevent the content from being sent when the data communication link is not connected.

[0088] The data transmission method provided by the embodiment of the present invention may include: S101, receiving target data sent by the client; S102, sending the target data to a serial port redirection component; wherein the serial port redirection component is a component that implements a virtual serial port on the baseboard management controller, and the serial port redirection component establishes a connection with a first forwarding node through the serial port; S103, using the serial port redirection component to send the target data to a second forwarding node, so that the second forwarding node sends the target data to a server; wherein the first forwarding node is a node connected to the client, and the second forwarding node is a node connected to the server. Compared with the current situation where data can only be sent when there is a network connection between the client and the server, the present invention uses the first forwarding node to receive the data of the client without changing the original client, and sends the data to the serial port redirection component, thereby using the serial port redirection component to send the data of the first forwarding node to the second forwarding node, so that the second forwarding node sends the data to the server, and realizes that data can be sent even when there is no network between the client and the server.

[0089] In order to make the present invention easier to understand, please refer to Figure 4 , Figure 4 A data transmission method applied to a second forwarding node provided in an embodiment of the present invention may include:

[0090] S201, receiving server data sent by a server.

[0091] The execution subject of this embodiment is the second forwarding node.

[0092] S202, sending the server data to the serial port redirection component; wherein the serial port redirection component is a component that implements a virtual serial port on the baseboard management controller, and the serial port redirection component establishes a connection with the second forwarding node through the network;

[0093] S203, using the serial port redirection component to send the server data to the first forwarding node, so that the first forwarding node sends the target data to the client; wherein the first forwarding node is a node connected to the client, and the second forwarding node is a node connected to the server.

[0094] The embodiment of the present invention can realize the functions of the client when the client has no network connection with the server. It reduces the use of the network and physical network card. Since the network connection is no longer required, the use of network equipment and network IP addresses can be saved, making it feasible for the client to have no internal network (the BMC network needs to be connected).

[0095] In order to make the present invention easier to understand, please refer to Figure 5 , Figure 5 A schematic diagram of a data transmission communication link provided by an embodiment of the present invention, from Figure 5 It can be seen that the nodes in the data transmission communication link include monitoring software, forwarding node A (corresponding to the second forwarding node above), forwarding node B (corresponding to the first forwarding node above), LAN side, serial side and monitoring server. The communication link has two directions. First, the monitoring software sends data to forwarding node B, forwarding node B sends data to the serial side, the data reaches the LAN side through the SOL connection, the data is sent to forwarding node A, and the data is sent from forwarding node A to the monitoring server. First, from the monitoring server to the monitoring software, the data direction is the opposite process.

[0096] As a client, the monitoring software needs to connect to a server connected to the network. Forwarding node B is the server end of a network connection. After receiving the data, the server of forwarding node B forwards the data to the serial port. The SOL in the figure is the data transmission link on the LAN side---Serial side. The data forwarded to the serial port by forwarding node B is transmitted to the LAN side. The LAN side is a client of a UDP network connection. It is represented by UDP-C later. Forwarding node A takes over the UDP client on the LAN side by marking the input and output (stdio) and forwards the data to the monitoring server. Since the monitoring server is the server end of a TCP network connection, forwarding node A is connected to the monitoring server through a client end of a TCP network connection. For ease of understanding, please refer to Figure 6 , Figure 6 A schematic diagram of a port connection relationship provided by an embodiment of the present invention, Figure 6Socket is a key abstract layer in computer networks that allows applications to communicate over the network. The working principle of Socket mainly involves two parts: server and client. Assume that the address of the monitoring server is ip-server and the port is 6000. The monitoring software needs to send the monitored data to ip-server. The process of constructing a communication link can include: 1. Modify the address and port of the monitoring server in the monitoring software configuration, modify the configuration, and the monitoring software will send the data to 127.0.0.1 (local) port 6000. 2. Data node B in the figure starts a socket server program, which listens to port 6000. When the monitoring software connects to the data node B program, or the monitoring software sends data to port 6000 of 127.0.0.1 (data node B), data node B will send the data to the serial side of the SOL connection. 3. After the data passes through the SOL connection, the data sent to the serial side in step 2 will reach the LAN side. After the LAN side receives the data, it establishes a data node A. Data node A is a socket client and connected to the monitoring server. 4. The data is sent to the monitoring server through data node A.

[0097] The present invention mainly solves the problem of transmission of monitoring data without network connection, and sends the monitoring data to the monitoring server through the function of BMC-SOL, so as to collect monitoring data and monitor the machine only with BMC network.

[0098] The following is an introduction to a data transmission device applied to a first forwarding node provided in an embodiment of the present invention.
