Abstract
The invention discloses a method for migrating file downloading tasks with zero delay, which is characterized in that a computer distributes residual file intervals and file resource addresses which are not downloaded to active terminal equipment or computers on an intranet before power failure, and processes file splicing and assembling are carried out after all computers receiving downloading tasks complete downloading of respective file interval contents. And sending a clearing instruction to the computer which receives the downloading task after the assembly is finished. The whole process is automatically finished, manual operation of a user is not needed, and searching for the live and drop computer is finished through the intranet broadcast message.
Description
Technical Field
The invention relates to the technical field of networks, in particular to a method for migrating a file downloading task with zero delay.
Background
When downloading the file, the user stops the task after closing the computer and needs to continue downloading after starting the computer next time. Or, transferring the downloading task from one computer to another computer requires manual copying, and the copying of the incomplete file part is slow and complicated.
Disclosure of Invention
The present invention aims to provide a method for migrating file downloading task without delay, which is aimed at the defects of the prior art.
In order to solve the problems, the technical scheme adopted by the invention is as follows:
a method for migrating file downloading tasks with zero delay comprises the following steps:
s1, when downloading files, the computer sends the remaining file interval information and file resource descriptor in the uncompleted downloading task as instruction data to the active terminal device or computer on the intranet before being forced to cut off the power supply; storing the downloaded file interval information and file content in the computer; storing the ip address and the host name of the terminal equipment or the computer receiving the handover download task to the computer, and simultaneously recording the ip address and the host name of the computer dispatching the task by the computer receiving the download task;
s2, when the computer to be assigned the task of the computer which finishes the download task comes online, the file content is initiatively transferred to the computer which assigns the task, the computer which assigns the task finishes the file splicing, or when the computer which assigns the task comes online, the computer which receives the task initiatively requests the finished file segment, the computer which assigns the task finishes the file splicing;
and S3, after the splicing and assembly of all the contents of the files are completed, sending a task clearing and file content command to all the computers receiving the tasks.
Further, the computer receiving the download task may also hand over the unfinished task to the next active terminal device or computer using the same method as S1, and this step may be repeated several times.
The further technical scheme is that the file resource descriptor is URL, thunder, BT and magnetic link address.
Adopt the produced beneficial effect of above-mentioned technical scheme to lie in: the invention relates to a method for realizing the continuous progress of a downloading task without extra time after a machine is closed when the machine is required to be closed and a file is not completely downloaded in a home or office network system. Or the computer is turned off before sleep when a high-definition movie is downloaded at home, and the unfinished file part can be handed over to the router to be finished continuously.
Drawings
FIG. 1 is a flow chart of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
As shown in fig. 1, a method for migrating a file download task with zero delay includes the following steps:
s1, when downloading files, the computer compelled to cut off the power supply and send the remaining file interval information and file resource descriptors (such as URL, thunder, BT, magnetic link address) in the unfinished downloading task as instruction data to the active terminal devices or computers on the intranet, and the searching for the active terminal devices or computers is completed through intranet broadcast messages; storing the downloaded file interval information and file content in the computer; and storing the ip address and the host name of the terminal equipment or the computer receiving the handover download task to the computer, and recording the ip address and the host name of the computer dispatching the task by the computer receiving the download task.
S2, splicing and assembling the file segments distributed on different computers, wherein 1, when the computer to be assigned the task of the computer which finishes the download task comes online, the file content is initiatively handed over to the computer to be assigned the task, and the computer to be assigned the task finishes the file splicing. Or 2, when the computer for dispatching the task is on line, actively requesting the completed file interval from the computer for receiving the task, and completing the file splicing by the computer for dispatching the task.
And S3, after the splicing and assembly of all the contents of the files are completed, sending a task clearing and file content command to all the computers receiving the tasks.
The computer that accepts the download task may also hand over the unfinished task to the next active terminal device or computer using the same method as S1, and this step may be repeated several times.
The invention relates to a method for realizing the continuous progress of a downloading task without extra time after a machine is closed when the machine is required to be closed and a file is not completely downloaded in a home or office network system. Or the computer is turned off before sleep when a high-definition movie is downloaded at home, and the unfinished file part can be handed over to the router to be finished continuously.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
Claims (3)
1. A method for migrating file downloading tasks without delay is characterized by comprising the following steps:
s1, when downloading files, the computer sends the remaining file interval information and file resource descriptor in the uncompleted downloading task as instruction data to the active terminal device or computer on the intranet before being forced to cut off the power supply; storing the downloaded file interval information and file content in the computer; storing the ip address and the host name of the terminal equipment or the computer receiving the handover download task to the computer, and simultaneously recording the ip address and the host name of the computer dispatching the task by the computer receiving the download task;
s2, when the computer to be assigned the task of the computer which finishes the download task comes online, the file content is initiatively transferred to the computer which assigns the task, the computer which assigns the task finishes the file splicing, or when the computer which assigns the task comes online, the computer which receives the task initiatively requests the finished file segment, the computer which assigns the task finishes the file splicing;
and S3, after the splicing and assembly of all the contents of the files are completed, sending a task clearing and file content command to all the computers receiving the tasks.
