With reference to figure 1, show the method flow diagram that application file is according to an embodiment of the invention downloaded, described method specifically can comprise:

The application file that step 101, the file server terminal request that buffer memory and described file server are erected at same Intranet in internal memory is downloaded, described file server is for providing the server of application file download service to described terminal.

In the embodiment of the present invention, file server belongs to a part for privately owned cloud security system, is located in same Intranet with end-frame, and terminal can access file server by connecting Intranet.

The file of multiple application program is kept at local disk by file server, to provide the download service of application programs file to terminal, terminal can send the acquisition request of application programs file to file server, file server receives the application file that the backward terminal of request returns request.

This application file, after first time receives the request of terminal, can be buffered in the internal memory of file server by file server.

Concrete, the step of the application file that the described file server terminal request that buffer memory and described file server are erected at same Intranet in internal memory is downloaded comprises:

Sub-step S11, check the current capacities of the internal memory of described file server;

Sub-step S12, the size of the capacity of described internal memory and described application file to be compared;

If the described memory size of sub-step S13 is greater than the size of described application file, then described application file is buffered in the internal memory of file server.

When application file is kept in internal memory, whether first check in internal memory has capacity can deposit this application file, by checking the current capacities of internal memory, and the size of current capacities and application file is compared, if memory size is greater than the size of application file, then application file can be kept in internal memory.

Step 102, according to described terminal, the behavior that described application file is downloaded, accesses, creates or upgraded to be screened the application file of buffer memory in described internal memory.

File server is after being cached to internal memory by application file, can also screen by application programs file, specifically, operation behavior according to terminal application programs file is screened, the operation behavior of terminal application programs file can comprise terminal can download behavior from this application file to file server requests, the behavior can be known by file server, terminal can also be comprised in this application program of its local IP access or create the behavior that this application program and application programs carry out upgrading, the behavior can be known by terminal itself and report file server, in concrete realization, other operation behaviors of terminal application programs file can also be comprised.

In the embodiment of the present invention, preferably, the described behavior carrying out downloading, access, create or upgrading according to terminal application programs file comprises the step that the application file of buffer memory in internal memory screens:

Sub-step S21, from described internal memory, delete the application file that number of times that described terminal request downloads described application file does not meet preset range.

According to the download behavior of terminal application programs file to when in internal memory, the application program of buffer memory is screened, the download behavior of terminal application programs file can be recorded, download time is not met to the application file of preset range, be considered as downloading the less and application file be of little use, it can be deleted from internal memory, thus make expired not have access application file deleted, automatically adjust that storage the most often uses.

In one preferred embodiment of the invention, the step that the described number of times deleting terminal request down load application program file from internal memory does not meet the application file of preset range can comprise:

Sub-step S21-1, detect download time of each application file in described internal memory.

If sub-step S21-2 described download time exceeds apart from the difference of current time the expiration-time value arranged for described application file, the number of times then described application file being downloaded described application file as request in the first preset time period is the application file of zero, and described application file is deleted in described internal memory, wherein, to be described file server return to described terminal the time that time of described application file or described file server receive the download request to described application file described download time.

Application file has corresponding download time, and download time is for file server to return time of application file to terminal, or file server receives the time of the download request of application programs file.

The application file that the download time distance current time of application file is distant can be considered as searching the less application file of download time, specifically, an expiration-time value is set, from expiration-time value to current time as being the first preset time period, application file download time in the first preset time period is 0, be equivalent to this application file download time distance present time difference beyond expiration-time value.

Its time of downloading for the last time can be found in the attribute or mark of each application file, detect this download time, and calculate the difference of distance current time, if difference exceeds default expiration-time value, to be then download time be 0 application file.

In another preferred embodiment of the invention, the step that the described number of times deleting terminal request down load application program file from internal memory does not meet the application file of preset range can comprise:

Sub-step S21-3, for each application file in internal memory, add up described terminal and ask to download the number of times of described application file in the second preset time period.

Sub-step S21-4, the number of times deleting statistics from described internal memory are less than the application file of preset value.

During terminal downloads application file, file server can to being downloaded into line item at every turn, when each application file screens in internal memory, statistics is in the second preset time period, terminal is to the download time of certain application file, for number of times be less than preset value to be considered as download time less, can delete.

In concrete realization, preset range can also be after the sequence from big to small of download time in preset time period, sequence is greater than certain ranking or certain ratio value, such as, before download time is greater than in sequence from big to small 50 or front 50%, do not meet this scope be considered as download less application file.

Preferably, in the internal memory of described file server, preset configuration file, in described configuration file, preserve the expired time arranged for described application file.The expired time that can arrange for each application file can be kept in profile, searches expired time by configuration file, when file is not made work within the time of specifying, then can be discharged.

Step 103, receive the download request of the application programs file that described terminal is sent by described Intranet.

Step 104, the application file that the request of extracting is downloaded in the internal memory of described file server return to described terminal.

Terminal can by connecting Intranet, and to file server requests down load application program file, after file server receives request, the application file downloaded from the request of extracting of internal memory transverse and longitudinal also returns.

Preferably, describedly in the internal memory of file server, extract the step that application file returns to terminal comprise:

Sub-step S31, in the internal memory of described file server, search whether there is described application file.

If sub-step S32 exists described application file, then extract described application file and return to described terminal.

If sub-step S33 does not exist described application file, then in the local disk of described file server, extract described application file return to described terminal, and described application file is buffered in the internal memory of described file server.

Application file is preserved and is all kept in the local disk of file server, application file requested in the past has then been kept in the internal memory of file server, when extracting the application file of request, first can search the application file that whether there is request from internal memory, if exist, then directly extract in internal memory and return, if do not exist, from disk, extract this application file and return, due to this application file requested mistake, can be buffered in the internal memory of file server, so that directly read from internal memory during request next time.

Owing to being far longer than the access speed to disk to the access speed of internal memory, therefore, the download efficiency of file server can be improved according to the embodiment of the present invention, and the access to disk can be reduced, extend the life-span of disk, improve the performance of server.Owing to being screened by the file in step 102 pair internal memory, thus application files maximum for terminal operation is preferentially placed in internal memory, and adjusts according to the operational circumstances of terminal, further increase the download efficiency to active file.
