Description

Intranet office software version downloading method based on server side dynamic allocation

Technical Field

The invention relates to the technical field of upgrading of intranet office software versions, in particular to a method for downloading intranet office software versions based on dynamic allocation of a server side.

Background

At present, with the continuous rising of the intelligent office field, in order to adapt to the office demands of different enterprise intranets, various office software based on a C/S mode is layered endlessly. Such as enterprise chat software, teleconferencing software, shared document software, etc., have become a standard for enterprise intranet offices. However, with the increasing number of enterprises, downloading and upgrading of various office client software has become time-consuming and inefficient gradually.

Intranet office software version downloads, generally include two modes. Mode 1, client initiative to server download. The client requests the new version file from the server actively according to the requirement, and the server judges that the request is received if the number of the connections currently being downloaded is smaller than the configured threshold value, otherwise, the downloading request of the client is refused. If the download request is denied, the client will continue to the server requesting version file downloads at random times within the time frame of the poll. And 2, the server informs the client in batches to the server for downloading the version file when the free connection exists in the download connection pool according to the configured upgrade plan.

Some upgrading modes of intranet office software versions all require the client and the server to perform point-to-point file stream transmission, and have the following 2 main disadvantages.

1. The method is completely dependent on the network bandwidth and the data stream processing capacity of the service end, brings huge pressure to the service server, and possibly affects the efficiency of other service processing.

2. Because of the limited bandwidth of the enterprise's offered version downloads, a software client may take a relatively long time to upgrade in its entirety.

Disclosure of Invention

Aiming at the defects of the background technology, the invention ensures that the version files in the group at the initial stage of distribution are fully covered and relatively scattered by an intranet office software version downloading method based on the dynamic distribution of the server, and prepares for the dynamic distribution of the subsequent server.

step 15, the server creates a set for each terminal of the current version upgrade, wherein the version type + the terminal number + the version number are used as keys, and the downloaded version of the terminal is fragmented into Value; meanwhile, the fragment information which is downloaded by a certain terminal is added to a set of redis in real time;

step 16, after the last 10% of terminal appointed software fragments are downloaded, the server informs all terminals in different network groups of requesting version downloading information from the server;

step 17, after receiving the notice of the server, the client initiates a version file downloading request to the server;

step 18, the server side carries out SDIFF calculation difference set on the downloaded sliced set and the version full-quantity sliced set of the current terminal in the redis, screens out the version sliced file numbers which are lack by the terminal, then traverses the version sliced file numbers which are lack by the terminal one by one, detects the terminal information which is provided with the sliced and provides the terminal information with the least download connection number for other terminals and accords with the preset local resource use strategy, returns the sliced to be downloaded and the target PC to the requesting party, returns if a piece of terminal information which accords with the requirement is found, otherwise informs the client side to continuously poll for 10 seconds and requests;

step 19, the client downloads the fragmented file according to the acquired fragmented information of the version to be downloaded and then to the corresponding target client host, the client monitors the resource score in real time, if the number of download connections corresponding to the continuous score for 3 times exceeds the threshold set by the server, the client can actively disconnect the latest download connection, and step 23 is carried out after the download is completed;

step 20, the client checks whether the number of the current fragmented files is complete, if not, the client continues to request the server to download the files, step 18 is repeated, and if so, step 21 is continued;

step 21, after downloading all versions of the fragments, checking the integrity of the fragments one by one according to the fragment information files, assembling all fragments into version files according to serial numbers, comparing MD5 values of the version files, and reporting the results to a server;

step 22, notifying the client to delete the fragmented files after the normal terminals of the network in the packet are upgraded;

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

As shown in fig. 1, 2, 3, in one embodiment, the method includes:

and step 1, uploading the version file by the management end page. And the user selects a version file to be upgraded at the system management end and uploads the version file.

And 2, dynamically calculating a recommended value according to the number of terminals required to be distributed by the version by the server, wherein the size of the fragments of the version file is 1M-5M (the fragments can be modified by a user according to the requirement), and cutting and storing the fragments of the version file.

And step 3, numbering the fragments and calculating the version file and the MD5 value of each fragment.

And step 5, reporting the IP information of the terminal. And the client software actively reports the fixed IP information to the server when each time of starting.

And 6, the server receives the IP information of the client and updates the IP information into the database.

And 7, the server groups the terminal equipment according to the network segment of the client and the number of the equipment in each group set by the user. The service end can also carry out terminal service grouping according to service requirements, and the user can designate the terminal grouping to carry out version distribution.

And 8, the client receives the IP list information in the group and detects that the IP list information is communicated with other terminal networks.

And 10, the server side respectively sends version upgrading notification to the devices in each group, and sends the encrypted version file information and the encrypted fragment information to the client side.

And 11, the client saves the version and the fragment information to the file, scores and reports the terminal idle rate according to preset scoring rules from the memory, the CPU and the network idle condition.

And 12, selecting terminals (10 are taken as examples here) with the score ranking accounting for 10% of the top of the group by the server according to the idle score ranking, and informing the terminals of downloading version fragmented files. And monitoring the consumption of the client resource in real time. The user can configure the downloading strategy corresponding to the client resource score at the server. The client monitors the PC resource consumption in real time, and if the continuous 3 scores exceed the last grade, the client reports the resource consumption to facilitate the server to dynamically allocate and download the target host next time. The client monitors the resource scores in real time, and if the number of download connections corresponding to the continuous 3 scores exceeds the threshold set by the server, the client can actively disconnect the latest download connection

Step 13, assuming the number of the version fragments is N, the number of the terminals 1 to 3 is the number 1 to N/3 of the downloaded version fragments, the number 4 to 6 is the number N/3 to 2N/3 of the downloaded version fragments, and the number 7 to 10 is the number 2N/3 to N of the downloaded version fragments.

And 14, after each terminal downloads a certain fragment, calculating the md5 value of the fragment, decrypting the stored fragment information, comparing, and informing a server if the fragment information is consistent, wherein the downloading of the certain file fragment of the terminal is completed.

And 15, the server creates a set for each terminal of the current version upgrade, wherein the version type, the terminal number and the version number are used as keys, and the downloaded version of the terminal is fragmented into Value. And meanwhile, the fragment information which is already downloaded by a certain terminal is added to the set of redis in real time.

And step 16, after the last 10% of terminal appointed software fragments are downloaded, the server informs all terminals in different network groups of requesting version downloading information to the server.

And step 17, after receiving the notification of the server, the client initiates a version file downloading request to the server.

And traversing the number of the version fragment file which is lack by the terminal one by one, detecting the terminal information of the fragment, providing the terminal information with the least download connection number for other terminals, conforming to a preset local resource use strategy, and returning the fragment to be downloaded and the target PC to the requesting party. If a piece of terminal information meeting the requirements is found, returning, otherwise notifying the client to continue polling for 10 seconds.

And 19, the client downloads the fragmented file according to the acquired fragmented information of the version to be downloaded and then to a corresponding target client host, the client monitors the resource score in real time, and if the number of download connections corresponding to continuous 3 scores exceeds the threshold set by the server, the client can actively disconnect the latest download connection. After the downloading is completed, step 14 is performed.

Step 20, the client checks whether the number of the current fragmented files is complete, if not, the client continues to request the server to download the files, step 18 is repeated, and if so, step 21 is continued.

And 21, after downloading all version fragments, checking the integrity of fragments one by one according to the fragment information file, assembling all fragments into a version file according to sequence numbers, comparing MD5 values of the version file, and reporting the result to a server.

And 22, notifying the client to delete the fragment file after the normal terminals of the network in the packet are upgraded.

According to the technical scheme, the quick distribution of the intranet office software is realized mainly through unified monitoring and dynamic distribution of the server side under the condition that resources required by normal office of a user are fully ensured, and the main differences are as follows:

1) The server side automatically carries out network grouping on the equipment according to the network connectivity of the terminal, and the server side can also carry out terminal business grouping according to the needs, such as trial-point equipment grouping and trial-point version issuing.

2) The version file is uploaded by the server and fragmented, the fragment size is dynamically calculated by the number of terminals to be distributed of the version, and the fragment size is between 1M and 5M.

3) In the initial stage of version file distribution, the server selects a certain proportion of terminals with relatively idle hardware resources according to the number of terminals of each network group to carry out version file segmented distribution. The method ensures that the file fragments of the version in the group at the initial stage of distribution are fully covered and relatively scattered, and prepares for the dynamic distribution of the subsequent server.

4) The traditional p2p downloading is that version information is exchanged by mutual communication among clients, and in the scheme, each file fragment required to be downloaded by a terminal is dynamically distributed by a server, so that the efficiency of acquiring a target fragment by the client is improved, and the retry times of the client are reduced.

5) And monitoring the consumption of the client resource in real time. The user can configure the downloading strategy corresponding to the client resource score at the server. The client monitors the PC resource consumption in real time, and if the continuous 3 scores exceed the last grade, the client reports the resource consumption to facilitate the server to dynamically allocate and download the target host next time. The client monitors the resource scores in real time, and if the number of download connections corresponding to the continuous 3 scores exceeds a threshold set by the server, the client can actively disconnect the latest download connection.

6) The server may dynamically increase or decrease the number of client download connections, as well as the download bandwidth of each connection. The client supports version fragment out-of-order downloading and supports a single fragment breakpoint continuous downloading mode.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the 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 scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
