Embodiment Construction

[0033] The preferred embodiments of the technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] figure 1 Is a schematic diagram of a network system according to an embodiment of the present invention, such as figure 1 As shown, the network system of this embodiment includes multiple BRASs and RADIUS servers, of which two or more BRASs are the master device, one BRAS is the backup device, and multiple ports on the same master device are backed up to the backup device. On multiple different ports, the ports that are mutually active and standby belong to a backup group, and the backup group negotiates the active / standby relationship through VRRP. Among them,

[0035] Each main device is used to receive the information of setting the main port as the user access port, and synchronously send the information to the standby device; used to encapsulate the DSLAM including user access and the main port as u...

Abstract

The invention provides a method for realizing user port positioning in a BRAS (Broadband Remote Access Server) multicomputer backup scene and a network system. The method comprises the following steps of: setting main ports in all backup groups into user interface ports and synchronizing information using the main ports as the user interface ports on a backup port in the backup group, wherein the access port information configured for the user by RADIUS (Remote Authentication Dial In User Service) is the main port of the backup group; and if the main port is abnormal for switching the main port and the backup port, a line is accessed from the corresponding backup port when a user is on line, wherein the BRAS corresponding to the backup port packages an authentication message comprising an DSLAM (Digital Subscriber Line Access Multiplexer) accessed by the user and access line information using the main port as the user access port and transmits the authentication message to the RADIUS so as to solve the problem of authentication failure caused by the change of the positioning line information of the user port after the backup group is switched in the BRAS multicomputer backup scene.

Description

Technical field [0001] The present invention relates to network communication technology, in particular, to a method and network system for realizing user port positioning in a BRAS (Broadband Remote Access Server) multi-machine backup scene. Background technique [0002] The broadband metropolitan area network service control layer is a peculiar layer where the service access network connects to the core switching network, and BRAS plays an important role in it. The BRAS located at the edge convergence layer of the broadband metropolitan area network is responsible for the authentication and billing gateway of various broadband access users and the user's service control gateway. It mainly undertakes the functions of service access control, user management, and address management. [0003] With the requirements for the high-quality guarantee of the services provided by the network, higher requirements are put forward on the performance and reliability of the BRAS products at the s...
