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 if the main BRAS-UP equipment breaks down, acquiring session information corresponding to the main BRAS-UP equipment, and sending the acquired 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 received session information. According to the technical scheme of the invention, the service interruption time of the user equipment is reduced, 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] The present application relates to the technical field of communications, in particular to a backup method and device for separation of transfer and control of a BRAS. Background technique [0002] BRAS (Broadband Remote Access Server, Broadband Remote Access Server) is used as the user's access gateway and the edge of the IP network. Since the control plane and the forwarding plane are tightly coupled together, the performance processing affects each other, and the control plane and forwarding plane cannot be fully utilized. Plane performance, low resource utilization. In order to solve the above problems, a virtualized BRAS with separated control plane and forwarding plane is proposed, that is, the vBRAS architecture. The control plane in the system) is realized by equipment, positioned as a user control and management component, which can be used to realize functions such as user control management, user access control, user authentication, authori...
