Abstract

The invention provides a user equipment migration method and device. The method comprises the steps of: receiving a migration notification message, wherein the migration notification message includesa network identifier, the identifier of first BRAS-DP equipment and the identifier of second BRAS-DP equipment; obtaining a network segment corresponding to the network identifier; notifying the firstBRAS-DP equipment to cancel network segment routing corresponding to the network segment; and notifying the second BRAS-DP equipment to publish the network segment routing corresponding to the network segment. By means of the technical scheme in the invention, the problem that a message is wrongly transmitted to the first BRAS-DP equipment can be avoided; and thus, the fact that the message is correctly transmitted to the second BRAS-DP equipment can be ensured.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a user equipment migration method and device. 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. The performance limit of the plane, the resource utilization rate is low. To solve the above problems, a vBRAS architecture in which the control plane and forwarding plane are separated is currently proposed. The control plane uses general-purpose servers to realize virtualization, and the forwarding plane uses dedicated equipment to achieve high-performance forwarding. [0003] Among them, the control plane can be realized by BRAS-CP (Control Plane, con...
