Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] The AAA client in the present invention uses the request message in the RADIUS protocol to perform switching control of the AAA server. During the entire process of the user requesting to access the Internet and use the Internet, the user will send an access message based on the RADIUS protocol to the AAA server through the AAA client. The AAA client will send an accounting request to the AAA server when the user is using the Internet, and the AAA client will use the above access request and accounting request to detect the fault of the AAA server. If a failure occurs, the AAA client will switch to another AAA server, and the other AAA server will provide authentication, authorization, and accounting services to users who need to access the Internet.

[0022] The present invention needs to set the response time threshold, the response overtime counter ...

Abstract

A method for controlling change-over of server includes using two AAA servers being backed up to each other to send request message to currently used AAA server based on far end switching-in dialing user service protocol, resetting time over frequency counter if relevant response message is received within threshold of response time or otherwise accumulating time over frequency by said counter, switching AAA client end from currently used AAA server to another AAA server when counting value is over set value.

Description

technical field [0001] The invention relates to servers, in particular to a control method for switching AAA servers. Background technique [0002] There are more and more Internet users all over the world. How to control user access is a crucial issue. Allowing legal users to use the Internet and charging them correctly is the most basic aspect of network access control for users. Require. RADIUS (Remote Access Dial-In user Service, Remote Access Dial-In User Service) protocol is an international general protocol for controlling Internet user access, based on the C / S (Client / Server, client / server) mode. [0003] figure 1 Shown is a schematic diagram of a user accessing the Internet through an AAA (Authentication, Authorization, Accounting, authentication, authorization, accounting) client. Before users use the Internet, they must go through identity authentication. The AAA client controls the access of users to the Internet, ensuring that only authenticated legal users c...
