Problems solved by technology

In this access mode, the web server is in a central position, and all visitors must be directly connected to the web server to access relevant content, which will cause the following problems: First, because the web server can accommodate visits Limited, if the website publishes important or hot news, it will bring a large influx of users, and the traffic of the website will rise sharply in a short period of time, resulting in a decrease in website access speed, or even paralysis
Second, if the website server is assumed to be far away from the user, the user's access request must go through many network nodes in the WAN, resulting in a long delay
However, if the system load is relatively high, placing more data will bring relatively large system overhead

Embodiment Construction

[0091] The present invention will be further illustrated by specific examples below, but it should be understood that these examples are only used for more detailed description, and should not be construed as limiting the present invention in any form.

[0092] Such as Figure 4 As shown, a data placement method applied in a content distribution network system, the method includes the following steps:

[0093] Step S401: Divide the data in the database of the main server into several data units {D 1 ,D 2 ,D 3 ,...,D n};

[0094] Step S402: the data unit {D 1 ,D 2 ,D 3 ,...,D n} into several data families;

[0095] Step S403: Calculate the sum T of the read and write requests of each slave server,

[0096] T = Σ j = 1 m ( r i , j + ...

Abstract

The invention belongs to the field of computer network and specifically discloses a data placement method and device applied to a content distribution network system. The data placement method comprises the steps of dividing data into a plurality of data groups and placing the data according to access frequency of a server in a main server. According to a network access accelerating method, common access objects are buffered in an edge server, and a data group in an original server is copied in the edge server and is converted into an object to be buffered in cache of the edge server through the data placement method, so that the access speed of the Internet is effectively increased.

Description

technical field [0001] The invention belongs to the field of computer networks, in particular to a data placement method and device applied in a content distribution network system. Background technique [0002] With the popularization of 3G, WiFi, WiMax and other networks, as well as the continuous emergence of dazzling smart terminals and rich dynamic applications (such as mobile phone reading, mobile TV, mobile commerce, etc.), this brings huge challenges to the operator's network. challenge. According to a report released by ITU in January 2012, at the end of 2011, there were 5.9 billion mobile phone users worldwide, and nearly 1.2 billion mobile broadband users. According to a report released by the China Internet Network Information Center in Beijing in January 2012, by the end of December 2011, the number of Internet users in China had exceeded 500 million, of which the number of mobile Internet users reached 356 million, a year-on-year increase of 17.5%.
