Problems solved by technology

[0003] At present, under the architecture of separation of transfer and control, user equipment accesses the Internet through the BRAS-UP device. When the BRAS-UP device fails, the services of all user equipment connected to the Internet through the BRAS-UP device are interrupted. , resulting in disconnection of these user devices, and the user's service experience is very poor

Abstract

The invention provides a BRAS (Broadband Remote Access Server) forwarding and control separation backup method and device. The method comprises the following steps: after user equipment passes the authentication, determining session information corresponding to the user equipment, and determining a tunnel backup group corresponding to the user equipment, wherein the tunnel backup group comprises amain tunnel between BRAS-CP (Control Plane) equipment and main BRAS-UP equipment and a backup tunnel between the BRAS-CP equipment and backup BRAS-UP equipment; sending the session information to themain BRAS-UP equipment through the main tunnel, so that the main BRAS-UP equipment performs data transmission according to the session information; and sending the session information to the backup BRAS-UP equipment through the backup tunnel, so that the backup BRAS-UP equipment performs data transmission according to the session information. According to the technical scheme of the invention, when the main BRAS-UP equipment breaks down, the service interruption of the user equipment can be avoided, the user service experience is improved, and rapid switching can be performed between the BRAS-UP equipment, so that the reliability of a forwarding level can be improved.

Description

Technical field [0001] This application relates to the field of communication technology, in particular to a backup method and device for BRAS transfer and control separation. Background technique [0002] BRAS (Broadband Remote Access Server) serves as the user's access gateway and the edge of the IP network. Because the control plane and the forwarding plane are tightly coupled together, the performance processing affects each other, and the control plane and forwarding cannot be fully utilized. The plane's performance and resource utilization are low. In order to solve the above-mentioned problems, a virtualized BRAS with separated control plane and forwarding plane, namely vBRAS architecture, has been proposed. Among them, the control plane can pass BRAS-CP (BRAS Control Plane, broadband remote access server control plane, that is, transfer and control separation vBRAS). The control plane in the system) device implementation, positioned as a user control management component...
