METHOD AND NETWORK SYSTEM FOR IMPLEMENTING USER PORT ORIENTATION IN MULTI-MACHINE BACKUP SCENARIO OF BROADBAND REMOTE ACCESS SERVER

摘要

A method and network system for implementing user port orientation in multi-machine backup scenario of broadband remote access server (BRAS) are disclosed. The method comprises: setting master ports in each backup group as user access ports and synchronizing information utilizing the maser port as user access port to the backup port in the backup group; configuring access port information which is the master port in the backup group for the user by remote authentication dial in user service (RADIUS) server; processing master-backup switch if the master port is abnormal and accessing line from the corresponding backup port when the user goes online; packaging the authentication message which comprises user access digital subscriber line access multiplexer and the access line information that the maser port acts as user access port and sending the authentication message to the RADIUS server by the corresponding BRAS of the backup port. With such solution, it can avoid authentication failure caused by backup group switch and implement user port orientation application in multi-machine hot backup scenario.
