Abstract

The embodiments of the invention disclose a user data migration method and a user data backup method, device and system, and belongs to the technical field of broadband access. The user data migration method is applied to a target BRAS (Broadband Remote Access Server) included in a broadband remote access system, and comprises the steps of: when an MPU (Microprocessor Unit) receives a migration message sent when a first target VM (Virtual Machine) satisfies a configured preset migration condition, selecting a VM satisfying a first preset condition from all online VMs of multiple BRASs, and determining the selected VM as a second target VM; the MPU generating a migration rule based on VLAN (Virtual Local Area Network) information of the first target VM and VLAN information of the second target VM, and sending the migration rule to a switch, so that when the switch receives a message sent to the first target VM, the switch forwards the message to the second target VM based on the migration rule, i.e., user data migration of the first target VM is realized, and then a physical server corresponding to the first target VM can be powered off. Therefore, the power consumption of the system is reduced, and idle system resources are simultaneously avoided.

Description

technical field [0001] The embodiment of the present invention relates to the field of broadband access technology, and in particular to a user data migration method and user data backup method, device and system. Background technique [0002] With the rapid development of broadband access technology, the application of broadband remote access system is becoming more and more extensive. As a new access gateway for broadband network applications, the broadband remote access system can provide users with basic services for accessing broadband, and also has functions such as authentication, billing, and account management for user accounts accessing broadband. [0003] In practical applications, such as figure 1 As shown, the broadband remote access system may include multiple broadband remote access servers (Broadband Remote Access Server, BRAS), and multiple virtual machines (Virtual Machine, VM) and multiple network cards may be deployed in each BRAS, and the multiple The ...
