Embodiment Construction

[0088] The data update method of the present invention will be described below in conjunction with specific hardware and network resources, where the update of game data is taken as an example.

[0089] The present invention is by setting up three-layer update mode (Internet bar computer is terminal layer, Internet bar server is Internet bar layer, Internet server is IDC layer), the update of game is updated from IDC layer to Internet bar layer and finally updated to terminal layer, through three-layer updated The method gathers the update amount of the terminal to the Internet bar layer, thereby effectively reducing the update amount, and solving the problems of a large number of concurrent bottlenecks of terminals and a huge update amount. The three-tier overall architecture can be found in image 3 .

[0090] in:

[0091] Terminal layer: the program name is BarClient, and its operating object is Internet users. It has the function of penetrating restoration and game updat...

Abstract

The invention provides a data block comparison based data updating method. The method comprises the following steps: (1) respectively dividing data in all versions into a plurality of data blocks, respectively extracting all documents in the data in each version and labeling map information of each data block against the data in each version; (2) establishing a corresponding index document against the data in each version; and (3) figuring out data blocks in the data in the previous version different from that in the data in the next version according to the attribute information of all documents and labeling map information in the index document in the next version when data are updated, and updating the data blocks. The data updating method greatly improves the speed of data updating by data division and specific updating algorithm, and further reduces load of a server by combining with an improved network download structure, and improves the performance of network transmission.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a data updating method. Background technique [0002] There are more than 100 popular online games in China, and more than 30% of the online games will be updated almost every day. The games in the computers of Internet cafes also need to be updated in time to meet the needs of Internet cafe netizens and solve this demand. There are two technical difficulties. One of the difficulties is that the number of machine terminals in all Internet cafes is very large, about 10 million or more. If all game updates are performed directly from the Internet server, the performance load of the server cannot handle it at all. The second difficulty is that the update volume of popular games is very large. If you look at the level of file update, the current average is about 40G per day. The huge update volume almost makes it impossible to update the game. It works normally in the Internet caf...
