Problems solved by technology

[0003] The dual-machine hot backup method requires users to spend additional costs to complete the backup function, but as the access device, the BRAS is expensive, and often few users will choose to purchase multiple BRAS to complete the backup function
The aggregation access method needs to complete the global synchronization of some resources. For distributed devices, it will occupy a large number of table resource resources to maintain global synchronization.

Embodiment Construction

[0029] figure 1 This is a flowchart of a method for backup of a BRAS device provided by an embodiment of this application, and the specific steps are as follows:

[0030] Step 101: When the main control board of the BRAS device finds that the first interface board is faulty, it sends a backup sub-interface activation command to the second interface board. The command carries all the main PPPOE (Point-Point- to-Pointprotocol over Ethernet, the backup PPPOE sub-interface identification of the sub-interface based on the Ethernet point-to-point protocol.

[0031] Step 102: The main control board of the BRAS device issues the user information maintained by itself of all the main PPPOE sub-interfaces connected to the first interface board to the second interface board.

[0032] Among them, the second interface board is the backup interface board of the first interface board, and the backup PPPOE sub-interfaces for all the main PPPOE sub-interfaces of the first interface board are created o...

Abstract

The invention discloses a backup method and device for BRAS (Broadband Remote Access Server) equipment. The method includes that a main control board of the BRAS equipment sends a backup slave interface activation command to a second interface board if determining failure of a first interface board, wherein the command carries backup PPPOE slave interface marks, corresponding to all main PPPOE slave interfaces of the first interface board, on the second interface board; and the main control board sends user information connected to all the main PPPOE slave interfaces of the first interface board and maintained by the BRAS equipment to the second interface board. Inter-board backup for the BRAS equipment is realized and backup cost is saved.

Description

Technical field [0001] This application relates to the field of backup technology, and in particular to a method and device for backup of BRAS (Broadband Remote Access Server) equipment. Background technique [0002] The current backup is generally performed through dual-system hot backup or aggregated access. [0003] The dual-system hot backup method requires users to spend additional costs to complete the backup function, but the BRAS as an access device is more expensive, and often few users choose to purchase multiple BRASs to complete the backup function. The aggregated access method needs to complete the global synchronization of some resources. For distributed devices, it will take up a large amount of additional table item resources to maintain global synchronization. Summary of the invention [0004] The embodiments of the application provide a backup method and device for BRAS equipment. [0005] The technical solution of this application is realized as follows: [0006] A...
