Abstract: The present invention relates to a method of virtual machine migration, which uses the protocol of the software defined networking technology. When a virtual machine is migrated across domains, the local controller will be notified rapidly for submitting the information of the virtual machine to the switch in advance. Thereby, without modifying the network configuration, the migrated virtual machine can provide service continuously; the optimal routing is achieved and thus improving the problem of triangle routing effectively.

Abstract: A validity management system for a digital file and a method for operating the same are provided. The system includes a file server that is connected with a file storage system and a blockchain for providing services of file preservation, verification and setting time validity. When an original file is received, an identification data is created and a hash value is calculated. The original file is uploaded to the file storage system that provides an original file address. The hash value, the identification data and the original file address are transmitted to the blockchain for creating a record. When any user requests for retrieving the original file, the original file is retrieved from the file storage system, and can be verified according to the record obtained from the blockchain. Afterwards, the user creates a copied file and decides accessibility of the copied file by setting time validity.
