Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the related art, a manager needs to collect logs, upgrade firmware or perform other operations in the BMC through a wired network. However, the number of servers in the machine room is large, and when a manager needs to detect each server in the machine room, the manager needs to repeatedly pull and insert cables, which is easy to increase the burden of the manager on maintenance work. In view of this, the present invention provides a data transmission method, in which a stable communication connection can be established between a client and a BMC through a wireless connection manner, so as to avoid a burden on a manager caused by repeated cable plugging and unplugging in the related art, and further improve the efficiency of the manager in performing maintenance and inspection on a server. Referring to fig. 1, fig. 1 is a flowchart of a data transmission method according to an embodiment of the present invention, where the method includes:
s101, broadcasting the Bluetooth information and the wireless network information of the BMC by the BMC so that the client generates a Bluetooth connection request and a wireless network connection request by using the Bluetooth information and the wireless network information respectively, and sending the Bluetooth connection request and the wireless network connection request to the BMC.
In the embodiment of the invention, two wireless connections are established between the client and the BMC: the data transmission method comprises the following steps of Bluetooth connection and wireless network connection (WIFI), wherein the Bluetooth connection is established at a high speed, but the bandwidth is small, and the Bluetooth connection is suitable for transmitting a small amount of data, so that the Bluetooth connection and the wireless network connection (WIFI) are used for transmitting necessary data for data transmission with a BMC in the embodiment of the invention; the wireless network has larger bandwidth and larger signal strength, and is suitable for transmitting a large amount of data in a long distance, so the wireless network is used for performing BMC data transmission with the BMC in the embodiment of the invention. It can be understood that, to establish the above two types of connections, the BMC needs to broadcast the bluetooth information and the wireless network information that are built in the BMC first, so that the client scans the two types of information to obtain the two types of information, and generates a corresponding bluetooth connection request and a corresponding wireless network connection request by using the information, and further requests the BMC to establish a corresponding connection. It should be noted that, the embodiment of the present invention does not limit the specific bluetooth information, the wireless network information, and the corresponding broadcast manner, nor the specific manner in which the client creates the bluetooth connection request and the wireless network connection request by using the bluetooth information and the wireless network information, respectively, and reference may be made to related technologies of bluetooth and wireless networks.
Further, it can be understood that the number of BMC devices in the room is large, and the client can scan a plurality of bluetooth information and wireless network information in the room area; in addition, the client needs to scan the bluetooth information and the wireless network information respectively to obtain a bluetooth information table and a wireless network information table, and then queries the information of the target BMC in the two tables, at this time, if the bluetooth information and the wireless network information of the BMC do not have associated information that can indicate a corresponding relationship, the client cannot accurately find the required information in the two tables, and thus it is difficult to establish bluetooth connection and wireless network connection with the same BMC. Therefore, the bluetooth information and the wireless network information of the BMC should have the above-mentioned association information. The embodiment of the present invention does not limit the specific association information, and may be, for example, an association identifier, or the same name, and may be set according to the actual application requirements. In the embodiment of the invention, in order to improve the identification efficiency, the same name is set for the Bluetooth information and the wireless network information of the same BMC. The embodiment of the invention does not limit the specific names, and can be set according to the actual application requirements.
In one possible case, the client generates a bluetooth connection request and a wireless network connection request by using the bluetooth information and the wireless network information, respectively, and sends the bluetooth connection request and the wireless network connection request to the BMC, which may include:
step 11: the client side respectively scans the Bluetooth information and the wireless network information to obtain a Bluetooth information table and a wireless network information table;
step 12: searching target Bluetooth information of the BMC in the Bluetooth information table, generating a Bluetooth connection request by using the target Bluetooth information and sending the Bluetooth connection request to the BMC;
step 13: and searching target wireless network information with the same name as the target Bluetooth information in the wireless network information table, and generating a wireless network connection request by using the target wireless network information and sending the wireless network connection request to the BMC.
S102, when receiving the Bluetooth connection request, establishing Bluetooth connection with the client, and sending the preset IP address to the client through the Bluetooth connection.
It should be noted that the embodiment of the present invention does not limit which bluetooth connection mode the BMC uses to establish a bluetooth connection with the client, and may refer to the related technology of bluetooth and select the connection mode according to actual applications. However, some bluetooth modes need to perform code matching operation, that is, the bluetooth connection can be established only after the pairing code is input, and considering that the BMC device does not usually have a display device and a keyboard and is inconvenient to perform pairing code input and display, the embodiment of the present invention can set the bluetooth connection mode of the BMC to be the Just Work mode (direct connection), and at this time, the above code matching operation is not required between the client and the BMC, which can simplify the bluetooth connection process, and further improve the efficiency of establishing the bluetooth connection between the client and the BMC.
In a possible case, before establishing the bluetooth connection with the client, the method may further include:
step 21: the BMC presets the Bluetooth connection mode as a Just Work mode;
correspondingly, the establishing of the bluetooth connection with the client may include:
step 22: the BMC establishes Bluetooth connection with the client in a Just Work mode.
Further, it should be noted that the preset IP address is an IP address that the client needs to use to access the BMC. In the related art, it is troublesome for a manager to perform a query operation in a Basic Input/output System (BIOS) of the BMC to obtain the IP address; in the embodiment of the invention, the IP address of the BMC is prestored, and then after the client establishes the Bluetooth connection with the BMC, the BMC sends the IP address to the client, so that the management personnel can be prevented from performing related query operation, and the efficiency of the management personnel in detecting and maintaining the server is improved.
S103, when the wireless network connection request is received, wireless network connection is established with the client, so that the client performs BMC data transmission with BMC by using the wireless network connection and the preset IP address.
It should be noted that the embodiment of the present invention does not limit which wireless network connection mode the BMC uses to establish the wireless network connection with the client, and may refer to the related technology of the wireless network and select the wireless network connection mode according to the actual application. However, some wireless network modes need to perform related authentication, which reduces the efficiency of establishing the wireless network connection between the client and the BMC, so in order to improve the efficiency, the embodiment of the present invention may set the wireless network connection mode of the BMC to an Open System mode (Open System), and at this time, authentication operation is not required between the client and the BMC, which can simplify the wireless network connection process, thereby improving the efficiency of establishing the wireless network connection between the client and the BMC.
In a possible case, before establishing the wireless network connection with the client, the method may further include:
step 31: the BMC presets a wireless network connection mode as an Open System mode;
correspondingly, establishing a wireless network connection with the client may include:
step 32: the BMC establishes wireless network connection with an Open System mode client.
Further, after the wireless network connection with the BMC is established, the client can access the IP of the BMC through the connection, and further perform BMC data transmission with the BMC. It should be noted that the embodiment of the present invention does not limit the specific data related to BMC data transmission, and for example, the specific data may be a KVM screen data (remote control), or may be other BMC data, and reference may be made to the related art of BMC. Further, in order to improve the security of the BMC and avoid malicious login, the BMC may also require the client to input relevant user information, such as a user name and a password, when the client accesses the IP, and allow BMC data transmission with the client after verifying the user information. It should be noted that, the embodiment of the present invention does not limit specific user information, and may be set according to application requirements.
In a possible case, the BMC data transmission between the client and the BMC using the wireless network connection and the preset IP address may include:
step 41: the client sends user information to the BMC by using the wireless network connection and the preset IP address;
step 42: the BMC verifies the user information and sends response information to the client by using the wireless network connection after the user information passes the verification;
step 43: and after receiving the response information, the client transmits BMC data with the BMC by using the wireless network connection and the preset IP address.
It should be noted that the response message is used to inform the client that the client is authenticated. The embodiment of the invention does not limit the specific form of the response information, and can be set according to the actual application requirements.
Further, the embodiment of the present invention does not limit whether the bluetooth connection capability and the wireless network connection capability are provided by the BMC natively or provided by an independent wireless communication module accessing the BMC. If the native communication capability of the BMC needs to be improved, the connection capability can be provided by the BMC native; if the compatibility needs to be improved, the connection capability can also be provided by the wireless communication module. In the embodiment of the invention, in order to improve compatibility, an independent wireless communication module can be arranged to provide the Bluetooth connection capability and the wireless network connection capability for the BMC, namely, the broadcasting and connection establishing functions can be controlled by the BMC to be executed.
In one possible scenario, the BMC broadcasts the bluetooth information and the wireless network information of the BMC, including:
step 51: the BMC broadcasts Bluetooth information and wireless network information by using the wireless communication module;
correspondingly, when a bluetooth connection request is received, the bluetooth connection with the client is established, including:
step 52: when the BMC receives the Bluetooth connection request by using the wireless communication module, the BMC establishes Bluetooth connection with the client by using the wireless communication module;
correspondingly, when receiving the wireless network connection request, establishing wireless network connection with the client, including:
step 53: when the BMC receives the wireless network connection request by using the wireless communication module, the BMC establishes wireless network connection with the client by using the wireless communication module.
It should be noted that, the embodiment of the present invention does not limit the connection manner between the wireless communication module and the BMC, and the connection manner may be set according to the input capability provided by the BMC. In one possible case, the wireless communication module is connected to the BMC via a USB interface. It should be noted that, the embodiment of the present invention is not limited to the specific structure of the wireless communication module, and can be set according to the actual application requirements.
Based on the embodiment, the BMC in the invention provides the Bluetooth connection mode and the wireless network connection mode, and simultaneously broadcasts the Bluetooth information and the wireless network information of the BMC to the outside. After receiving the bluetooth information, a client needing to establish connection with the BMC firstly utilizes the information to establish a bluetooth connection request, and utilizes the request to establish bluetooth connection with the BMC so as to receive a preset IP address sent by the BMC through the bluetooth connection, wherein the address is used for accessing the BMC, because the bluetooth connection speed is higher and the address is more suitable for transmitting a small amount of information compared with a wireless network, the client can quickly obtain the IP address of the BMC through the bluetooth connection; in addition, after the client receives the wireless network information of the BMC, the client can further utilize the information to construct a Bluetooth connection request, and utilize the request to establish wireless network connection with the BMC so as to carry out BMC data transmission with the BMC through the wireless network connection and the preset IP address. In other words, stable communication connection can be established between the client and the BMC in a Bluetooth connection mode and a wireless network connection mode, wired connection does not need to be established, burden on managers caused by repeated cable plugging in and out in the related art can be avoided, and the efficiency of the managers in maintaining and checking the server can be improved.
