Title: METHODS AND DEVICES FOR SWITCHING A VIRTUAL INTERNET PROTOCOL ADDRESS
Abstract:
Methods and devices for switching a virtual internet protocol (VIP) address are provided. In one implementation, the method may include sending to a control center of a VIP address system a first address resolution protocol (ARP) mapping message for mapping a VIP address to a VM address of a virtual machine (VM) of the VIP address system. The control center may be configured to determine the VM corresponding to the VM address as the master VM using the VIP address. The VIP address system may include one or more VMs connected to one or more virtual switches, the one or more VMs and one or more virtual switches being located in one or more hosts that are connected to the control center via a cloud network. The method may further include sending a notification message from the control center determining the master VM to a VM in the VIP address system.
