Embodiment Construction

[0022] The method of the present invention is described in detail below with reference to the accompanying drawings. The flow chart of the whole system is as follows figure 1 As shown, the system architecture diagram is shown in figure 2 shown.

[0023] Detect the content and health status of the background server, set up a system resource detection module, and detect the content and health status of the background server in real time;

[0024] In order to avoid the single point of failure of the load balancing system, the load balancing system itself adopts a dual-machine system configuration to achieve high availability. Data synchronization between the active and standby systems is used to maintain the consistency of client connection information. When a system is in a fault state, The standby load balancing system automatically takes over the service;

[0025] The interception and analysis of user requests, the monitoring of the health status of the background server o...

Abstract

The invention relates to a load balancing system based on content, comprising load balancing based on content, inspection of content and health status of a backend server, self high availability of load balancing and load balancing algorithm thereof, wherein, the load balancing based on content refers to that a system works in the seventh layer of a seven-layer model of an OSI Internet, and belongs to the load balancing of an application layer; the inspection of content and health status of a backend server is provided with an inspection module of system resources to inspect the content and the health status of the backend server in real time; in order to avoid single-point failures of the load balancing system, the load balancing system uses dual-system configuration to realize the high availability; a main system and a standby system keep the consistency of connection information at client by data synchronization. When a system is in the failure status, a standby load balancing system automatically takes over services. The system of the invention changes the goofy load balancing mode of the traditional IP layer load balancing, and thus, the load hit rate can be effectively increased. The load balancing system does not require that the backend server stores the same content, which largely saves server resources.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a content-based load balancing scheduling system. Background technique [0002] Today's computer technology has entered a network-centric computing period. Due to the simplicity, ease of management and ease of maintenance of the client / server model, the client / server computing model has been widely adopted on the Internet. In the late 1990s, the emergence of the World Wide Web (WWW) brought online information with pictures and texts to the general public with its simple operation mode. The Web is also changing from a content delivery mechanism to a service platform. A large number of services and applications ( Such as news services, online banking, e-commerce, etc.) are all carried out around the Web. This promotes the dramatic growth of Internet users and the explosive growth of Internet traffic. The rapid development of the Internet brings huge challenges to n...
