Abstract: Embodiments of the present invention provide a method, a device, and a system for realizing disaster tolerance backup. The method includes the following steps: a device with an active-standby function determines a current state of the device with the active-standby function, after it is determined that the current state is an active state, the device with the active-standby function issues reachable route information to a connected routing device, where the device with the active-standby function and a device of which a current state is a standby state have a same IP address, the reachable route information includes route information relevant to the IP address, so that the IP address is reachable, and the device with the active-standby function and the device of which the current state is the standby state are backup devices for each other. The present invention can realize remote disaster tolerance backup and avoid service interruption.

Abstract: A virtual network function (VNF) deployment method and apparatus is provided. The method comprises: obtaining a virtual network function descriptor (VNFD), where the VNFD includes input parameter information, input adaptation information, and VNF descriptor information; the input parameter information includes N pieces of management unit information, each piece of management unit information is used to describe an attribute of a management unit; the input adaptation information is used to indicate a mapping relationship between the management unit and a logical management unit; mapping management units corresponding to the N management unit identifiers to the N logical management units based on the input adaptation information; and creating the VNF on the N logical management units based on the VNF descriptor information. The embodiments of this application are applicable to VNF deployment process.
