The present invention relates to a
service mobility management method and
system in a virtualized environment. The method includes: when the FN needs to be migrated, the first
virtual machine notifies the service management node of the
virtual machine migration event through the
virtual machine manager; the service management node notifies the second The virtual
machine manager to which a virtual
machine belongs sends a cache instruction; after the virtual
machine migration process is completed, the second virtual machine notifies the service management node of the virtual machine migration completion event through the virtual machine manager; the service management node sends a notification to the first virtual machine The virtual machine manager to which it belongs issues a data transfer instruction, and the virtual machine manager to which the second virtual machine itself belongs transfers the received cached data to the second virtual machine. The present invention enables the virtual machine manager to cache the
business data involved in the virtual machine during the migration process of the virtual machine, and forwards the cached data to the migrated virtual machine manager after the migration is completed, thereby maintaining the continuity of the business session without interruption.
