Such a method enables preinstalled files such as an operating system and application software to be installed on the prototype only once at the beginning, thereby reducing procedures and man-hours.

However, there are still many defects in this method of common technology, especially when carrying out multi-variety and large-scale pre-installed file download tasks, it often adopts a file pre-installed server to respond to the download requests of multiple clients at the same time to provide The download of the image file will cause the load of the file pre-installation server to be too large, which will not only greatly reduce the download efficiency, but even cause the network to be paralyzed.

In addition, when performing multi-variety and large-volume pre-installed file download tasks, in order to improve download efficiency to a certain extent, common technologies also use multiple file pre-installed servers to simultaneously respond to download requests from multiple clients to provide image files. However, the unified scheduling between the file pre-installation servers is often not very good. Some are idle, while others are very busy. The effective resources of the file pre-installation servers are not allocated reasonably, resulting in a waste of resources. . As a result, although the number of file pre-installed servers has been increased and the production cost has been increased, the production efficiency has not been significantly improved.

Moreover, in common technologies, when the number of clients on the production line increases and the amount of downloading tasks increases, if the number of original file pre-installation servers in the production line network cannot meet the requirements, it is impossible to dynamically update the number of file pre-installation servers in real time. The load status is monitored or an early warning prompt is issued to add a file pre-installation server, thereby limiting the improvement of download efficiency.

Detailed ways

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Please refer to FIG. 1 and FIG. 2. FIG. 1 shows the production network environment in which the load-balanced file pre-installation system and method of the present invention operate, and FIG. 3 shows the overall structure of the load-balanced file pre-installation system of the present invention. As shown in the figure, a plurality of file pre-installation servers 10 (1...n) are connected to the production network, and multiple pre-installation files are stored in each file pre-installation server 10, and can be sent when connected to the production network. A registration request; a plurality of client computers 11 (1...n) are also connected in the production network, and each client computer 11 can send a preinstallation file if the preinstallation file in the file preinstallation server 10 is to be downloaded when it is connected to the production network. In addition, a scheduling server 12 is also provided in the production network, and the scheduling server 12 and each file preloading server 10 are respectively connected with each client 11 through the same hub 13, and the scheduling server 12 receives and preloads files according to The registration request sent by the server 10 sets up a registration data table, and after receiving the pre-installation request sent by the client 11, sends a load query request to each file pre-installation server 10 according to the registration data table, requiring each file pre-installation server 10 to transmit A load status response is sent back to perform a balanced load scheduling, and then according to the balanced load scheduling, the file pre-installation server 10 with the smallest load status among the file pre-installation servers 10 is assigned to execute the client's file pre-installation.

Please refer to Fig. 2 now, in the file pre-installation system of load-balanced load of the present invention, dispatching server 12 and file pre-installation server 10 are set up to be connected by the connection mode of TCP/IP agreement among the figure, and when file pre-installation server 10 and dispatcher After the connection is established, the server 12 sends a registration request to the scheduling server 12. After receiving the registration request and creating a registration data table, the scheduling server 12 returns a registration result to the file preinstallation server 10 that sent the registration request.

Please refer to FIG. 4 , which is a flow chart of the steps of the load-balancing file preinstallation method of the present invention. As shown in the figure, in order to achieve the purpose of the present invention, the file preinstallation method includes the following steps in order:

Connect multiple file preinstallation servers storing multiple preinstallation files to the production network, and send a registration request by the file preinstallation server at the same time (step 100);

Connect a plurality of client computers to the production network, and simultaneously send a preinstallation request (step 101) by the client computers;

Establish a scheduling server in the production network to receive registration requests sent by each file pre-installation server and create a registration data table, which stores the address information of each file pre-installation server and the pre-installed The path information (step 102) of loading file;

In addition, after step 102 is executed, a step 103 can be executed immediately, and the scheduling server returns a registration result to the file preloading server sending the registration request after establishing the registration data table;

Utilize the scheduling server to receive the preloading request sent by the client, and send a load query request to each file preloading server according to the registration data table, and require each file preloading server to return a load status response (step 104);

At this time, a step 105 can also be provided to dynamically monitor the load status of each file pre-installation server in real time according to the load status response sent back from each file pre-installation server by the scheduling server, and when all file pre-installation servers reach the download limit, take the initiative Issue an early warning prompt that the file pre-installation server should be added;

Utilize dispatching server to record and analyze the load status response sent back from each file preloading server, judge whether there is a queue waiting to download this preloading file in each file preloading server (step 106);

When there is a queue waiting to download this preinstalled file in the file preinstalled server, utilize the scheduling server to select the file preinstalled server as the download server to perform the client computer's file preinstalled task (step 107); and

When there is no queue waiting to download the pre-installed file in any of the file pre-installation servers, the scheduling server is used to select the file pre-installation server with the smallest load resource occupancy rate as the download server to perform the file pre-installation task of the client (step 108).

It should be noted that each file pre-installation server mentioned in the above method steps has an independent tool for downloading pre-installation files, which is used to download the pre-installation files in this file pre-installation server to the client Machine (client) end. The tools for downloading pre-installed files do not communicate with each other and do not work together.

The working method of downloading pre-installed files is as follows: 1. It is pre-set that several download queues can be opened at the same time to perform download tasks. 2. Each queue responds to the client's request. In order to improve the download performance, when the number of clients in the queue is insufficient, the download will not be performed. At this time, this queue is called the waiting download queue. When the number of clients in the queue reaches The default value is to download. At this time, the queue is called the download queue, and the download requests of all clients in the queue will be completed at one time, saving network bandwidth and server resources. 3. Set the time when the waiting queue becomes a download queue, because when the number of clients cannot reach the preset number in a short period of time, downloading must be performed in order to quickly execute the file pre-installation task to complete the shipment of the clients.

Every time there is a channel for downloading, a part of the resources of the file pre-installation server will be consumed. Therefore, when evaluating the load status, the percentage of the number of waiting queues to the total number of queues and the number of downloading queues to the total number of queues are calculated. The percentage is used as a reference indicator. The reason why percentages are used instead of the number of waiting queues and the number of downloading queues is that different file pre-installation servers may have different total opening queues, so if the percentage is not considered, the number of waiting queues may be different from the number of downloading queues. The file pre-installation server with a small sum of queues actually has its opened queues fully occupied, so there is no free queue to use, so subsequent download tasks must wait for a previous queue to be downloaded and a new queue is free. It can be downloaded, which wastes the download time and reduces the shipping efficiency. (Note: The main indicator of load status and resource consumption is the data communication volume of the hard disk of the file pre-installation server. The number of its work queue will directly affect the resource occupation of the hard disk, thereby affecting the download efficiency. As for the utilization rate of the CPU, it does not It is not an indicator that affects download efficiency, so it can be ignored).

The load balancing file preloading system and method of the present invention will be further described in detail below. The present invention utilizes TCP/IP technology and a scheduling algorithm to achieve load balancing among multiple file preloading servers. The present invention establishes a scheduling server in the production network of multi-client/multi-file pre-installation servers, and the scheduling server can save the address information of all file pre-installation servers in the production network, as well as the address information of all file pre-installation servers in all file pre-installation servers. The path information (not including the name of the file preinstallation server), for example, can be: /HP/fenway/ch01.img. The way of obtaining the address information of the file pre-installed server is: when the file pre-installed server has installed the corresponding mirror image file and is connected to the production network to start, the file pre-installed server sends the dispatching server to the dispatching server through the connection mode of the TCP/IP protocol. Send a registration request, and after receiving the registration request, the scheduling server will save the address information of the file pre-installation server for subsequent query or call, so as to achieve the plug-and-play of the file pre-installation server and make the download efficiency of file pre-installation Get elastic adjustments. In addition, the path information of the pre-installed files in the file pre-installed server (it can be the corresponding path information formed by the brand, model of the file pre-installed server, and the language version of the pre-installed files) is also saved in the scheduling server , and then establish the corresponding relationship between the path information of the preinstalled file and the serial number of the file preinstalled server, and save it in the scheduling server. Then, each file pre-installation server will create a corresponding pre-installation file download file according to the path information of the pre-installation file for the client computer to download and use. When the client expects to download the required pre-installed file, it sends a pre-installed request to the scheduling server, and gives the number or name of the pre-installed file to be downloaded, and the scheduling server finds out the pre-installed file that needs to be downloaded according to the number or name. The path information of the file (this path information does not include the name of the file pre-installation server), and then the scheduling server sequentially obtains the address information of each file pre-installation server, and adds it to the front of the pre-installation file path information to form a complete The path information is in the form of: //serverip/HP/fenway/ch01.img, and then communicates with the file pre-installation server through TCP/IP protocol, asking whether this pre-installation file exists on this server? How many queues are currently downloading queues that are executing download tasks? How many queues are waiting for the download queue? And is there a queue waiting to download this preinstalled file? And save the above query results, and then visit all the file pre-installation servers in this way, and save all the query results. Finally, analyze the data of the query results, if a file pre-installation server has a queue waiting to download the pre-installation file, then select this file pre-installation server as the download server, so that all clients in the queue can download the pre-installation file at the same time , so as to ensure the maximum utilization of bandwidth and load resources in the file preinstallation server; if there is no file preinstallation server with a queue waiting to download the preinstallation file in the production network, then the scheduling server will calculate each file preinstallation How many queues are downloading and waiting to download in the server, and calculate the percentages of the two to the total number of queues set to open, and then select the file pre-installation server with the smallest sum of the two percentages as the download server, so that It is ensured that the file pre-installation server performing the download task is always the server with the smallest load resource occupancy, thereby ensuring the fastest execution of the download task and improving production efficiency.

The load balancing file preinstallation system and method of the present invention will be described below through a specific embodiment.

Please refer to FIG. 5 , which is a structural block diagram of a specific embodiment of the present invention. As shown in the figure, assume that there are two file preinstallation servers 10 (imageserver1 and imageserver2) in the file preinstallation system of the balanced load of the present invention, and the two file preinstallation servers 10 are all in the state of no download task at present, and both Six download queues are preset, and each download queue can simultaneously accommodate 30 clients 11 (client1 to client30) for downloading.

After a client computer 11 (client1) sends a preinstallation request (download request) to the scheduling server 12 in the file preinstallation system, the scheduling server 12 is based on the preloading request (download request) of the client computer 11 (client1) and its machine Code, access a data table to find out that the pre-installed file that this client 11 (client1) will download is: /hp/fenway/1.img, then the scheduling server 12 communicates with two file pre-installed servers 10 through the TCP/IP protocol (imageserver1 and imageserver2) connect, and inquire about the download status (load situation) of two file preinstallation servers 10 (imageserver1 and imageserver2) respectively, these two file preinstallation servers 10 return to scheduling server 12-response data (load situation response) , where the Flag value can be used to indicate the percentage of the number of downloading queues to the total set number of queues, and the percentage of the number of queues waiting to download to the total set number of queues. When the Flag value is 0, it means that the file pre-installation server does not have this pre-installation file; if the Flag value is 1, it means that there is such a pre-installation file. When the Flag value is 2, it means that there is a queue waiting to download this pre-installation file. In this embodiment, it is assumed that the pre-installed file /hp/fenway/1.img to be downloaded by the client 11 exists in two file pre-installed servers 10 (imageserver1 and imageserver2), and the response data (load status) returned by the two Response) results are: imageserver1: 1, 0%, 0%; and imageserver2: 1, 0%, 0%. Because the two latter two bits are all 0%, 0%, it means that the load status of the two file preinstallation servers 10 is in the state of no download task, so the scheduling server 12 randomly selects the file preinstallation server 10 (imageserver1) as the download server , and put the preinstallation request (download request) of the client 11 (client1) on the file preinstallation server 10 (imageserver1), and simultaneously the file preinstallation server 10 (imageserver1) opens a waiting queue for downloading. Assume that another client 11 (client2) sends a preinstallation request (download request) to the scheduling server 12, requesting to download the preinstallation file /hp/fenway/1.img, then two file preinstallation servers 10 (imageserver1 and imageserver2) The results of the response data (load status response) returned to the scheduling server 12 are: imageserver1: 2, 0%, 1/6; and imageserver2: 1, 0%, 0%. Because the Flag value returned by file preinstallation server 10 (imageserver1) is equal to 2, it shows that there is a queue waiting to download this preinstallation file, so scheduling server 12 will select file preinstallation server 10 (imageserver1) as the download server, file preinstallation server 10 (imageserver1) puts the preinstallation request (download request) of the client computer 11 (client2) in the waiting download queue. Assume that 28 clients 11 (client3 to client30) request to download the preinstallation file /hp/fenway/1.img (download request) successively, then these requests will all be placed on the file preinstallation server In the waiting download queue of 10 (imageserver1), since the number of clients in the waiting download queue has reached 30, the waiting download queue starts to execute the download task and becomes a download queue. When the 31st client computer 11 (client31) requested to download the preinstalled file /hp/fenway/1.img, two file preinstalled servers 10 (imageserver1 and imageserver2) returned the response data (load status response) to the scheduling server 12 ) results are: imageserver1: 1, 1/6, 0%; and imageserver2: 1, 0%, 0%. Because the Flag values of the two are all equal to 1, it shows that there is no queue waiting to download this pre-installed file in two file pre-installed servers 10 (imageserver1 and imageserver2), so the scheduling server 12 will further compare the number of queues being downloaded. The percentage of the total set queue number and the queue number waiting for downloading account for the percentage sum of the total set queue number, so as to select the file pre-installation server with the minimum sum of the two percentages as the download server, that is: file pre-installation server 10( imageserver1)=1/6+0%; file preinstallation server 10 (imageserver2)=0%+0%, imageserver2<imageserver1, so the load resource occupancy rate of file preinstallation server 10 (imageserver2) is less than file preinstallation server 10 ( imageserver1), so the scheduling server 12 will select the file preinstallation server 10 (imageserver2) as the download server, and put the preinstallation request (download request) of the 31st client computer 11 (client31) into the file preinstallation server 10 (imageserver2) At the same time, the file preinstallation server 10 (imageserver2) opens a new waiting queue for downloading.

Although the present invention is disclosed above with the aforementioned preferred embodiments, they are not intended to limit the present invention. Those skilled in the art should realize that without departing from the scope and spirit of the present invention disclosed in the appended claims of the present invention, all changes and modifications are within the scope of the claims of the present invention.
