Load sharing method, system and access server

Abstract

The embodiment of the invention provides a load sharing method, a load sharing system and an access server. The load sharing method comprises the following steps of: transmitting request information to at least two authentication authorization accounting servers; receiving state information transmitted according to the request information by the at least two authentication authorization accounting servers; determining a load sharing proportion between the at least two authentication authorization accounting servers according to the state information; and performing load sharing between the at least two authentication authorization accounting servers according to the load sharing proportion. The embodiment of the invention realizes the dynamic regulation of the load sharing proportion between the authentication authorization accounting servers by the access server, and improves the access performance of a user.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a load sharing method, system and access server. Background technique [0002] With the continuous development of Internet technology, the demand for communication has gradually extended from traditional low-speed services such as telephone, fax and telegraph to high-speed Internet access, videophone and video-on-demand and other broadband services. Higher and higher, the low-speed Internet access method of the traditional dial-up modem can no longer meet the needs of users. [0003] At the same time, more and more users are connected to the MAN, and the service requirements of users are also expanding. The broadband MAN is gradually developing towards a multi-service bearer network. Broadband Remote Access Server (BRAS for short) has flexible access authentication methods, effective address management functions and powerful user management ...

Problems solved by technology

[0007] However, when a large number of users are connected, a certain RADIUS server may be too busy to respond to the user's authentication information in time, and the BRAS can only process according to a fixed load sharing ratio, and cannot The state is adjusted, which will cause some users to fail due to authentication timeout and cannot access the network normally
