Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of resuming a transfer when a file transfer is interrupted for the purpose of executing an application from a server to a client (resume function: preempt
The present invention relates to an application download resume method and a system thereof for performing ive resume).

[0002]

2. Description of the Related Art Conventionally, this kind of download resume system is used to transfer a file existing on a server to a client. Conventional download resume systems include, for example, Get Right (Hea) which is shareware that is fully executed after provisional execution.
dLight SoftWare) or the like is used. This download resume system recovers a transfer failure due to a transfer interruption due to a congestion state in a communication network or a line disconnection in a transfer of a file existing in a remote machine to a client.

[0003] This download resume system,
It comprises a storage device for storing the transferred file, a transfer processing device for controlling transfer resumption, a display device for displaying the file transfer status and the result, and the like. The storage device stores the file transferred from the remote machine. The transfer processing device grasps the transfer status from the server, and when the transfer fails, restarts the transfer from that point. The transfer status and the transfer result are displayed on the display device through the processing of the transfer processing device.

In such a download resume system, file transfer is resumed (resume function) for the purpose of executing an application from a server to a client. In such a download resume system, when transferring a file from a server to a client, the transfer status of how far the file has been transferred is not monitored, so that when the transfer fails, the entire file size is transferred again. For this reason, the transfer time increases, and the network load increases. In addition, when the transfer fails, a retransfer instruction operation (considered by the user, for example, an EXE click operation in a window system) on the client is required, and the operation load on the client increases.

[0005] Techniques have been proposed for eliminating such a large transfer time, increasing the network load, and eliminating the operation burden on the client. For example, if a failure occurs in a received file during file transfer between computers, the receiving computer automatically recovers as much as possible (for example, JP-A-63-280350).
No. “File transfer control method”). In addition, by using the one-way function, the file requested by the receiving terminal is obtained only by transmitting the remaining file data that could not be received to the transmitting terminal using the file data received until the file transfer was interrupted. (For example, Japanese Patent Application Laid-Open No. 9-265428, "File Transfer System").

[0006]

As described above, in the above conventional example, when a failure occurs in a received file, the receiving side automatically recovers the file. However, automatic execution of the transferred application on the client and execution after checking the new version of the application cannot be performed. In other words, there is room for improvement from the viewpoint of shortening the time until the application is executed, reducing the network load, and eliminating the burden of the retransfer instruction operation and the application execution on the client.

[0007] The present invention is to solve such a problem in the prior art, and resumes a transfer interruption (resume function) when performing a file transfer for the purpose of executing an application from a server to a client.
Automatic execution of the transferred application on the client becomes possible, and version (version) inspection based on the date of the file to be transferred, file version information, etc. is carried out, and a new version of the application can be executed at all times.

Next, the operation of the first embodiment will be described. FIG. 2 is a flowchart showing a processing procedure of the operation of the first embodiment. 1 and 2, transfer information from the input device 2 is input to the transfer information input unit 31 (step S1). The transfer information input unit 31 transmits the name or IP address of the server 6 and the transfer target file name in the input transfer information to the status monitoring unit 32. The state monitoring unit 32 that has received this information determines whether the server 6 and the transfer target file 61 therein exist through the reception waiting processing unit 33 (steps S2 and S3).

If the server 6 and the transfer target file 61 do not exist (S2, S3: No), a message indicating the absence thereof is sent to the output device 4 and displayed on the display device (step S10). When the server 6 and the transfer target file 61 exist (S2, S3: Ye
s), the state monitoring unit 32
Send a receive request. The reception waiting processor 33 sends the request to the server 6 so as to transfer the file by executing the HTTP protocol or the FTP software in response to the request (step S4). The start of the file transfer request to the server 6 is displayed on the screen of the display device of the output device 4.

The server 6 which has received the file transfer request starts transmitting the transfer target file 61 to the client 1 which has issued the file transfer request, and notifies the reception waiting processing unit 33 of the start of the transmission (see FIG. 4). Step S
5). The state monitoring unit 32 monitors the reception waiting processing unit 33 to determine the reception state from the server 6 (Step S).

Notifies the state monitoring unit 32 of the occurrence of this interruption. The state monitoring unit 32 sends the interruption occurrence to the output device 4 and displays the screen on the display device. Further, the state monitoring unit 32
The transfer target file 61 that has already been transferred is sent to the storage unit 34. The storage unit 34 stores the transfer target file 61 as the storage target file 51 in the storage device 5 (Step S7). This state of storage is notified to the state monitoring unit 32, from which it is sent to the output device 4 and displayed on the screen by the display device.

Next, the status monitoring unit 32 that has received the interruption status information instructs the reception waiting processing unit 33 to transfer the untransferred portion in the transfer target file 61 based on the interruption status information. The reception waiting processing unit 33 transmits the transfer request again to the server 6 together with the interruption status information (step S4). The interruption / resumption status at this time is sent to the output device 4 and displayed on the screen by the display device. The server 6 that has received the transfer request together with the interruption status information resumes transmission of the untransferred portion of the transfer target file 61 (step S5).

When the data of the transfer target file 61 has been transferred to the end and completed, the state monitoring unit 32 sends the transfer target file 61 to the storage unit 34 together with the interruption state information. If the interruption has not been performed, the transmission of the interruption state information is not executed. The storage unit 34 stores the transfer target file 61 in the storage device 5 as the storage target file 51. The storage unit 34 that has received the interruption state information performs additional saving, and if there is no interruption state information, newly saves it. The storage status at this time is sent to the output device 4 and displayed on the screen by the display device (step S8). After the storage is completed, the execution unit 35 executes the storage target file 51 stored in the storage device 5, that is, the application,
The execution status at this time is sent to the output device 4 and displayed on the screen by the display device (step S9).
