Description

Server migration method and server migration system

The present invention relates to a control method and an electronic system. Specifically, the present invention relates to a server migration method and a server migration system applied to low power Bluetooth technology.

Under the existing client-server network architecture, each client will connect to the main network service address (URL, Web API, specific port, etc.) according to the default settings. Today, users need to migrate a large number of devices or equipment for website-related services. For example, users want to set up website services on on-premises services such as company internal websites or enterprise private clouds. Each device must know the new server address to establish a connection. However, the current device redirection method is time-consuming and labor-intensive or easily blocked by corporate firewall settings or private network settings.

Therefore, the above technology still has many defects, and it is necessary for practitioners in this field to develop other suitable server migration methods and server migration systems.

One aspect of the present invention relates to a server migration method. The server migration method is used to configure the server to which a receiving device is connected to be converted from a first server to a second server. The server migration method includes the following steps: a first sending device generates a message according to an operation instruction and setting data of a second server to generate a plurality of segmented messages according to the message; the first sending device sequentially broadcasts the plurality of segmented messages to a Bluetooth broadcast channel; a receiving device receives the plurality of segmented messages from the Bluetooth broadcast channel; and when the receiving device combines the plurality of segmented messages to obtain a message, the receiving device obtains setting data and an operation instruction according to the message, and replaces the connection setting of the receiving device connected to the first server with the setting data according to the operation instruction, so that the receiving device is connected to the second server.

Another aspect of the present case involves a server migration system. The server migration system includes a receiving device and a first sending device. The receiving device is configured to switch the server to which it is connected from the first server to the second server. The first sending device is configured to generate a message according to an operation instruction and the setting data of the second server, and to generate a plurality of segmented messages according to the message. The first sending device is configured to sequentially broadcast the plurality of segmented messages to a Bluetooth broadcast channel. The receiving device is configured to receive a plurality of segmented messages from a Bluetooth broadcast channel. When the receiving device combines the plurality of segmented messages to obtain a message, the receiving device is configured to obtain the setting data and the operation instruction according to the message, and to replace the connection setting of the receiving device connected to the first server with the setting data according to the operation instruction, so that the receiving device is connected to the second server.

In view of the shortcomings and deficiencies of the above-mentioned prior art, this case provides a server migration method and server migration system. This case uses low-power Bluetooth technology to broadcast messages, without the need for manual settings of a large number of electronic products, without the need for Bluetooth devices to pair with each other and without being interfered by the original network construction (such as firewall settings). In addition, multiple sending end devices can be used to accelerate the server migration of a large number of electronic products.

The following will clearly illustrate the spirit of the present invention with diagrams and detailed descriptions. After understanding the embodiments of the present invention, any person with ordinary knowledge in the relevant technical field can make changes and modifications based on the techniques taught by the present invention without departing from the spirit and scope of the present invention.

The words "include", "including", "have", "contain", etc. used in this article are open terms, meaning including but not limited to.

The terms used in this document generally have the ordinary meanings of each term used in this field, in the context of this case and in the specific context, unless otherwise specified. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing this case.

FIG. 1 is a circuit block diagram of a server migration system 100 according to some embodiments of the present invention. The server migration system 100 includes a transmitter device 110 and a plurality of receiver devices (eg, a receiver device 120A and a receiver device 120B).

In some embodiments, the transmitter device 110 includes an electronic product with Bluetooth Low Energy (BLE) technology function. For example, the transmitter device 110 can be implemented as a laptop computer. However, the type of the transmitter device 110 is not limited to this embodiment. It should be noted that Bluetooth Low Energy technology function is a personal area network technology designed and sold by the Bluetooth Technology Alliance, which is mainly used in the fields of medical care, sports and fitness, security protection and home entertainment.

In some embodiments, the plurality of receiving devices include electronic products with low-power Bluetooth technology functions. For example, the receiving device 120A and the receiving device 120B can be a tablet computer, a Bluetooth speaker, or a smart phone, respectively. However, the types and quantities of the receiving device 120A and the receiving device 120B are not limited to this embodiment.

In some embodiments, the transmitter device 110 and a plurality of receiver devices (eg, the receiver device 120A and the receiver device 120B) may be implemented as the same type of electronic product.

In some embodiments, the transmitter device 110 and a plurality of receiver devices (eg, the receiver device 120A and the receiver device 120B) may be implemented as different types of electronic products.

Nowadays, users need to migrate a large number of devices or equipment for website-related services. For example, if a user wants to set up a website service on an on-premises service such as a company's internal website or an enterprise private cloud, each device must know the new server address to establish a connection. Then, the device redirection methods include manually setting new addresses for each device, obtaining the configuration data of the new server through the original server, and pre-setting to listen to the network port or try to connect to a specific address to obtain the new server configuration data. The above-mentioned methods of manually setting new addresses for each device, such as manual settings, scanning barcodes, and downloading files, require time and manpower. The other two methods mentioned above are often easily blocked by corporate firewall settings or private network settings. This case will describe how to improve the above problems in the subsequent content.

To make the operation of the server migration system 100 of the present invention easier to understand, please refer to Figures 1 to 3 together. Figure 2 is a flow chart of the steps of the server migration method 20 according to some embodiments of the present invention. Figure 3 is a detailed data transmission flow chart of the server migration system 100 of Figure 1 according to some embodiments of the present invention. The server migration method 20 includes steps 21 to 24.

In step 21, please refer to FIG. 1 first. The user wants to migrate a large number of electronic products (e.g., the sending end device 110, the receiving end device 120A, and the receiving end device 120B) from the old server (e.g., the server 900) to the new server (e.g., the server 130). Then, please refer to FIG. 2 and FIG. 3 together. The user selects an electronic device (e.g., the sending end device 110) from the large number of electronic products to set. At process S1, the sending end device 110 is used to divide the message of the setting data and operation command of the new server (e.g., the server 130) input by the user into multiple divided messages. For example, the sending end device 110 divides the message into three different divided messages.

In some embodiments, a user may use an application on his/her own mobile device (ie, a device different from the receiving device 120A and the receiving device 120B) to configure a large number of electronic products.

In step 22, the transmitter 110 sequentially broadcasts a plurality of segmentation messages unilaterally within the transmission range (approximately greater than 100 meters) of the low power Bluetooth technology through the Bluetooth broadcast channel BC in FIG. 1. For example, in the above example, the transmitter 110 is used to sequentially broadcast three different segmentation messages on the Bluetooth broadcast channel BC. It should be noted that the transmitter 110 and the plurality of receivers (e.g., the receiver 120A and the receiver 120B) are not connected to each other through the Bluetooth broadcast channel BC.

In some embodiments, at process S2, the sending end device 110 is further used to segment the message of the configuration data and operation instruction of the new server (e.g., server 130) into multiple data segments according to the communication standard (e.g., the protocol specification after Bluetooth 4.0). Then, the sending end device 110 is further used to encrypt the multiple data segments according to its own built-in default key to generate multiple encrypted data segments. Furthermore, the sending end device 110 is further used to generate multiple segmented messages according to the multiple encrypted data segments and the multiple header data segments.

In some embodiments, the header field includes a protocol identifier, a sender identifier, a message identifier, a total number of messages, and a message number.

It should be noted that the header data segment can be adjusted according to actual needs. For example, the total number of messages and the message number are processed and stored in the data segment before encryption. Alternatively, the data segment and the header data segment are combined before encryption. Furthermore, data compression technology is used to reduce the message length and timestamp. In addition, the message is hashed or error correction codes are added to ensure the integrity of the message.

In step 23, please refer to Figures 1 to 3, after the receiving device 120A and the receiving device 120B are turned on by the user, they unilaterally receive all the information in the channel from the Bluetooth broadcast channel BC. Since the operation of the receiving device 120B is similar to that of the receiving device 120A, the following paragraphs only use the receiving device 120A as an explanation.

In some embodiments, at process S3, after the receiving device 120A is powered on by the user, the receiving device 120A attempts to connect to the old server (i.e., the server 900) along the sub-path L11 of the path L1 according to the default data (i.e., the configuration data of the server 900). If the receiving device 120A can connect to the server 900, the receiving device 120A executes process S8 without executing processes S4 to S7. The details of process S8 will be described in the following paragraphs.

In process S4, if the receiving device 120A cannot connect to the old server (ie, the server 900), the receiving device 120A activates its own Bluetooth broadcast function to unilaterally receive all messages in the Bluetooth broadcast channel BC.

In process S5, please refer to Figures 1 to 3, the receiving device 120A determines whether the multiple broadcast signals in the Bluetooth broadcast channel BC match the protocol identification codes of the multiple segmentation messages and the sender identification code of the sending device 110 according to the header data segment of one of the multiple segmentation messages. If the header data segment matches, the receiving device 120A selects the multiple segmentation messages from the multiple broadcast signals.

Next, in process S6, after the receiving device 120A selects a plurality of segmented messages from a plurality of broadcast signals, the receiving device 120A collects the segmented messages broadcasted in the Bluetooth broadcast channel BC by the sending device 110 according to the total number of messages and the message number of the header data segment of one of the plurality of segmented messages in the Bluetooth broadcast channel BC. For example, in the example of step 22 above, when the receiving device 120A receives one of three different segmented messages from the Bluetooth broadcast channel BC, the receiving device 120A collects the other two different segmented messages according to the total number of messages and the message number of one of the header data segments of the corresponding segmented messages.

In step 24, at process S7, after the receiving device 120A collects all the segmented messages, the receiving device 120A decrypts the multiple encrypted data segments according to the key corresponding to the default key of the sending device 110, thereby obtaining multiple data segments. The receiving device 120A combines and restores the multiple data segments into a message, and replaces the connection setting of the receiving device 120A to the server 900 with the setting data of the server 130 according to the operation instruction, so that the receiving device 120A is connected to the server 130 along the path L2 of Figure 1.

At process S8, please refer to Figures 1 to 3, when the receiving device 120A successfully connects to the old server (i.e., server 900) along the sub-path L11 of the path L1, the configuration data of the new server (i.e., server 130) is transmitted to the receiving device 120A, and the receiving device 120A is guided to the new server (i.e., server 130) along the sub-path L12 of the path L1. It should be noted that the receiving device 120A successfully connects to the server 900 along the sub-path L11 of the path L1, which means that the receiving device 120A passes the configuration of the firewall FW.

Through the operation mechanism of the embodiment, the present case uses the carousel message of low-power Bluetooth technology to perform server migration without the need for manual configuration of a large number of electronic products, without the need for mutual pairing of Bluetooth devices and without interference from the original network construction (such as firewall settings).

FIG. 4 is a schematic diagram of a server migration system 200 according to some embodiments of the present invention. Similar to the server migration system 100 of FIG. 1, a user wants to perform server migration (e.g., migration from server 900 to server 230) for a large number of electronic products (e.g., a sending end device 110, a receiving end device 120A, and a receiving end device 120B) more quickly. The server migration system 200 of the present invention further provides the function of accelerating the deployment of a large number of products by different sending end devices.

To make the accelerated deployment function of the server migration system 200 of this case easier to understand, please refer to Figure 4. The server migration system 200 includes a sending end device 210A, a sending end device 210B and a plurality of receiving end devices (e.g., a receiving end device 220A and a receiving end device 220B. It should be noted that the difference between the server migration system 200 and the server migration system 100 is that there is an additional sending end device 210B.

Then, the sending device 210B transmits a plurality of segmented messages on the Bluetooth broadcast channel BC. The contents of the plurality of segmented messages transmitted by the sending device 210B are the same as the plurality of segmented messages transmitted by the sending device 210A. That is, the sending device 210B divides the message (i.e., including the setting data and operation instructions of the server 130) into a plurality of data segments according to the built-in default key, encrypts the plurality of data segments into a plurality of encrypted data segments according to the default key, and matches the plurality of data segments with a plurality of header data segments to generate a plurality of segmented messages respectively. In one embodiment, the transmitting device 210A and the transmitting device 210B are set at different positions. For example, in a Bluetooth receiving range where a large number of electronic devices are integrated, the transmitting device 210A and the transmitting device 210B can be respectively set on both sides of the Bluetooth receiving range, thereby covering the Bluetooth receiving range where a large number of electronic devices are integrated through the different Bluetooth transmitting ranges of the transmitting device 210A and the transmitting device 210B.

It should be noted that the transmitter device 210A, the transmitter device 210B, the receiver device 220A and the receiver device 220B are not connected via the Bluetooth broadcast channel BC. Further, the default key built into the transmitter device 210A is the same as the default key built into the transmitter device 210B.

According to the above-mentioned embodiments, the present invention provides a server migration method and a server migration system. The present invention uses low-power Bluetooth technology to broadcast messages, and performs server migration without the need for manual configuration of a large number of electronic products, without the need for Bluetooth devices to pair with each other, and without being interfered by the original network configuration (such as firewall configuration). In addition, multiple sending-end devices can be used to accelerate server migration of a large number of electronic products.

Although the present invention is disclosed in detail with the embodiments as above, the present invention does not exclude other feasible embodiments. Therefore, the protection scope of the present invention shall be subject to the scope defined by the attached patent application, and shall not be limited by the aforementioned embodiments.

For those skilled in the art, various modifications and improvements can be made to the present invention without departing from the spirit and scope of the present invention. Based on the above embodiments, all modifications and improvements made to the present invention are also covered by the protection scope of the present invention.
