Abstract

The invention provides a virtual IP switching method, device and system, relates to the field of artificial intelligence, in particular to cloud computing and cloud network technologies, and can be applied to an intelligent cloud scene. According to the specific implementation scheme, the method comprises the following steps: receiving a free ARP message sent by a virtual machine of which the virtual IP is successfully switched; generating a first forwarding table of a high-availability virtual IP according to the free ARP message; the first forwarding table is packaged in a first UDP message through a VXLAN; and synchronizing the first UDP message to other virtual routers. According to the embodiment, rapid switching of the high-availability virtual IP is realized.

Description

technical field [0001] The present disclosure relates to the field of artificial intelligence, in particular to cloud computing and cloud network technologies, and can be applied in intelligent cloud scenarios. Background technique [0002] High-Availability Virtual IP Address (HaVip for short) is a private network IP resource that can be created and released independently. HaVip can be used in conjunction with high-availability software (such as Keepalived) to build high-availability active and standby services and improve business availability. There are various sources of demand for HaVip at present. After traditional customers migrate from the Underlay network to the Overlay network, they need to modify and adapt load balancers or other compromise solutions, which cannot be smoothly migrated. Some services are strongly dependent on the Havip mechanism, and the inability to migrate to a load balancer will greatly hinder migration to an overlay network (such as the cloud...
