Abstract

The invention provides a cross-data center disaster backup method and a BRAS system, wherein the method comprises the steps that an access control device receives the connection state information transmitted by a forwarding device, and transmits the connection state information to a first controller; the first controller judges whether the access control device fails or not according to the connection state information sent by the access control device; when it is determined that a first access control device in the plurality of access control devices fails, searching a second access control device corresponding to the first access control device according to a pre-configured takeover relationship, and issuing a control instruction to the second access control device; and if the access control device receives a control instruction sent by the first controller, obtaining the user session information stored by the second access control device from a pre-established database used for storing the user session information, and guiding the forwarding device to process the service flow according to the user session information.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to a cross-data center disaster backup method and a BRAS system. Background technique [0002] The remote disaster recovery solution can improve the disaster recovery capability of data against various security factors by establishing backup systems in different locations. For BRAS (Broadband Remote Access Server, Broadband Remote Access Server) forwarding control separation system, the access control equipment of BRAS such as BRAS-CP is deployed in the data center (Data Center, DC) to guide forwarding equipment BRAS-CP The UP forwards user services. To implement remote disaster recovery for the BRAS-CP device in the BRAS forwarding control separation system, you can perform dual-device backup for the BRAS-CP device in two different DCs, so that the active BRAS-CP device in the active DC or When a link fails, user services can be quickly switched to the standby...
