Abstract

The present invention discloses a method for switching of a virtual Internet protocol address. The method is applied in a virtual IP system, the virtual IP system comprises a control center and a plurality of physical machines connected with the control center through a cloud network, and the physical machines are provided with virtual machines (VM) and virtual switches connected with the VMs. Themethod comprises the steps of: sending a received first address resolution protocol (ARP) mapping message configured to correspond a virtual IP address to a VM address to the control center to allowthe control center to determine a VM corresponding to the VM address as a main VM using the virtual IP address; and sending a notification message of the control center determining the main VM to theVM in the virtual IP system to forward data associated with the virtual IP address to the main VM. According to the embodiment of the invention, a main and standby relation of the VM does not need tobe controlled by users, and IP address drift on the cloud network can be achieved.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a method and device for switching virtual Internet protocol addresses. Background technique [0002] In the physical network of the prior art, IP (Internet Protocol, Internet Protocol) address drift refers to that in a dual-machine backup environment, using a shared virtual IP address, the peer end cannot perceive the IP address of the local server during server switching. A technique where the address changes. In IP address drifting, the physical server can declare its own IP address through ARP (Address Resolution Protocol, Address Resolution Protocol), and use this IP address to provide services, limited by the number of ports on the physical server, usually the range of IP address drifting is not More than a hundred physical servers. [0003] In the cloud network, the VIP (Virtual IP, virtual IP) address used by the physical machine is allocated and ...
