Example Embodiment

[0043] The following describes the present invention in further detail based on the drawings and embodiments:

[0044] The English abbreviations in this description are as follows:

[0045] DNS: Domain Name Service / Server domain name service (device);

[0046] QoS: Quality of Service;

[0047] URL: Uniformed Resource Locator;

[0048] IDC: Internet Data Center Internet data center;

[0049] HTTP: HyperText Transmation Protocol.

[0050] according to figure 2 , image 3 with Figure 4 , The present invention includes a balancing device that periodically obtains server information reported by each server and updates related entries of the machine. The balancing device includes an update and storage module for the server content table and the server status table, and the balancing device is provided with Corresponding optimization calculation and selection module. This load balancing device implements communication with the server through a private protocol. This private protocol is b...

Abstract

Based on user's request, looking up server content list, which holds all information of servers, is carried out. The servers containing requested content are obtained through search. Based on actual working condition, the servers possible to provide content are selected out. The optimal server is determined through dynamic optimization selection. The server content list reflects IP addresses of servers, as well as ID, name and route of content. The state table, which is updated and receives report from each server, of server reflects instant operating states of each server. The server possible to provide content is determined after eliminating servers with unhealthy content and high load. The invention provides the method for balancing loads in high efficiency and low cost.

Description

technical field [0001] The invention relates to electric communication technology, in particular to a content-oriented load balancing method and equipment. Background technique [0002] Before the content delivery network CDN appeared, the content was stored in a centralized manner on the network, and all requests from users were processed by the central server. When the network content existed in text, graphics and other formats, the processing capacity of the central server was not large. , the bandwidth occupation of the backbone network is not explosively increasing, and the impact of unstable network transmission on the transmission of these low-data-volume, low-QOS media is not yet obvious. [0003] The current network content is developing towards multimedia, and a large number of large A / V streaming media files appear. These files are characterized by large data volumes. Generally, each file is several hundred megabytes. In order to ensure browsing quality, the netwo...
