Downloading notification message can be preestablished by management server: will wait that the client that receives file to be distributed is divided into many groups; The effective download time section that can carry out that file downloads is divided into a plurality of sub-time periods; Set up the corresponding relation of groups of clients and sub-time period.
Introduce how distribution of document of management server below in detail.
At first, the keeper determines to carry out file distributing to which client, according to the performance of file server and the quality of whole network, the lot number of file distributing is set on management server then, and the total effective download time section that can carry out that file downloads is set.
The lot number of the file distributing that management server is provided with according to the keeper and the effective download time section that can carry out that file downloads treat the client packets that receives file to be distributed and to described effective download time section carry out segmentation.For example, wait that the client that receives file to be distributed has 10000, these 10000 clients are averaged division, per 1000 clients are divided into one group, then are divided into ten groups of clients altogether.The effective download time section that can carry out that file downloads be December 1 00:00:00 to 00:00:00 on December 11, should be effective download time section be divided into 10 sub-time periods, be respectively: the 00:00:00-12 month 1 December 1 23:59:59, the 00:00:00-12 month 2 December 2 23:59:59...... all the other by that analogy, set up the one-to-one relationship of each groups of clients and each sub-time period then, as shown in Table 1.Each groups of clients corresponding file download the sub-time period just the above file download sub-time period of groups of clients corresponding download in notification message.
Groups of clients and corresponding file thereof are downloaded the sub-time period in table one, the embodiment of the invention
| Groups of clients | File is downloaded the sub-time period |
| First group | The 00:00:00-12 month 1 December 1 23:59:59 |
| Second group | The 00:00:00-12 month 2 December 2 23:59:59 |
| The 3rd group | The 00:00:00-12 month 3 December 3 23:59:59 |
| The 4th group | The 00:00:00-12 month 4 December 4 23:59:59 |
| The 5th group | The 00:00:00-12 month 5 December 5 23:59:59 |
| The 6th group | The 00:00:00-12 month 6 December 6 23:59:59 |
| The 7th group | The 00:00:00-12 month 7 December 7 23:59:59 |
| The 8th group | The 00:00:00-12 month 8 December 8 23:59:59 |
| The 9th group | The 00:00:00-12 month 9 December 9 23:59:59 |
| The tenth group | The 00:00:00-12 month 10 December 10 23:59:59 |
Each groups of clients and corresponding file thereof are downloaded the sub-time period and are not limited to shown in the table one, for example, can also be that first groups of clients corresponding file is downloaded the sub-time period and is set to the 00:00:00-12 month 1 December 1 12:00:00, second groups of clients corresponding file downloaded the sub-time period and is set to the 12:00:00-12 month 2 December 1 23:59:59, and all the other groups of clients corresponding file are downloaded the sub-time period and can be set according to the performance of file server and the quality of whole network.
Management server is after having set up groups of clients and the one-to-one relationship between the sub-time period, the sub-time period of carrying out the file download of each groups of clients correspondence and the download address information sets composite document download notification message of file to be distributed are sent to corresponding client, and client can be known sub-time period and the download address information that file is downloaded of carrying out like this.Wherein, the download address information of file to be distributed has different representations according to file transfer protocol (FTP) between management server and the client different, just can file in download according to this download address client.File is downloaded effective download time segment information that can also comprise can carrying out of setting in the management server in the notification message file downloads.
In the above-described method, the method that client is divided into groups can also be: the title according to client computer is divided into groups; Perhaps divide into groups according to the IP address of client computer, for example the client I P address client that is in 0.0.0.0-100.100.100.100 is divided into one group, and the client that client ip address is in 100.100.100.101-200.200.200.200 is divided into another group ... suchlike group technology.Then according to the number of groups of clients, determine the number of the sub-time period of effective download time section.
The segmented mode that file is downloaded the sub-time period also is not limited to average mode of dividing, can also be divided into a plurality of sub-time periods according to network overall condition and actual needs, only need to guarantee that the number of sub-time period is identical with the number of groups of clients that promptly file of each groups of clients correspondence is downloaded the sub-time period and got final product.
In the above-described document distribution method, file server can be one, also can be a plurality of.If a file server, then client is downloaded at the file of regulation and is carried out the file download in the sub-time period.Avoid a plurality of clients to carry out file to the identical file server at one time and downloaded the impact that file server is caused, simultaneously owing to be to be provided with the sub-time period that management server carries out the file download to client, the keeper only need set client sum and can carry out that file downloads total effective download time section, reduce artificial participation workload, improved time availability.The described method of the embodiment of the invention can only dispose a file server, has reduced the requirement to hardware resource, has reduced cost.
