Method and device for distributing loads to multiple AAA servers in network

Abstract

The invention provides a method and device for distributing loads to multiple AAA servers in a network. The method comprises that after a user receives an access request, a network access server determines the expense of each of the multiple AAA servers which route the authentication request message of the user to the network, based on the expenses, the network access server selects a first AAA server from the multiple AAA servers in the network, and the network access server distributes the authentication request message of the user to the first AAA server.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and a device for load distribution among multiple Authentication Authorization Accounting (AAA) servers in a network. Background technique [0002] With the development of Internet technology, communication requirements have expanded from traditional low-speed services such as telephone, fax, and telegraph to high-speed broadband services such as Internet access, videophone, and video-on-demand. Users need higher and higher Internet access speeds, and the low-speed Internet access mode of the traditional dial-up modem is almost impossible to meet the user's requirements. [0003] At the same time, more and more users are accessing the metropolitan area network, and therefore the user's service requirements are expanding, and the broadband metropolitan area network has a tendency to develop into a multi-service bearer network. The Broadband Remote Access S...
