Method for implementing automatic backup and load balance of proxy servers

Abstract

The invention discloses a method for balancing loads of proxy servers, which comprises the following steps: adding a network device between a terminal user and the proxy servers (group); detecting whether the proxy servers work normally or not, and marking the proxy servers with faults; sending a request of establishing the connection from the terminal user of an inner network to Internet; leading the network device to analyze the request sent from the terminal user of the inner network; detecting whether to use the proxy servers to accelerate or not, if the detection result is no, directly sending to the Internet, and then finishing; if the detection result is yes, enumerating the list of the current servers which work normally, selecting one proxy server with the smallest load according to the load algorithm, sending an access request to the proxy server and then finishing. The method can equally distribute the network access request to various proxy servers, effectively utilize the proxy servers and improve the overall performance and the overall stability of the proxy servers.

Description

Technical field [0001] The invention relates to the technical field of telecommunications, in particular to a method for realizing automatic backup and load balancing of the proxy servers by managing multiple proxy servers in a network device. Background technique [0002] With the development and application of the Internet and information technology, although network bandwidth continues to increase, it still cannot meet people's demand for bandwidth. In order to solve this problem, users usually use proxy servers to speed up the Internet. [0003] The traditional proxy server deployment method is that multiple proxy servers proxy multiple internal networks to access Internet, and the proxy servers are not related to each other. This has many limitations: On the one hand, if a proxy server fails, the internal network it is proxying cannot access the Internet and cannot automatically back up network requests to another proxy server. On the other hand, the internal network that eac...

This has many limitations: on the one hand, if a proxy server fails, the internal network it proxies cannot access the Internet, and cannot automatically back up network requests to another proxy server

On the other hand, each proxy server is responsible for different internal networks, which will cause some proxy servers to have excessive network traffic and some proxy servers to be idle. It is impossible to evenly distribute network traffic to each proxy server and effectively use proxy servers.
