Abstract
An instance running device (10) determines, based on VNF instances through which a traffic flow passes and an order of software pieces through which the VNF instances pass, an order of the VNF instances to be migrated, and performs control so that the VNF instances are migrated to another instance running device (10) on the basis of the determined order of the software pieces migrated.
Claims5
A communication system comprising:
- a determination unit configured to determine, based on software pieces through which a traffic flow passes, the software pieces running on a predetermined server, and determine, based on an order of the software pieces through which the traffic flow passes, a migration order of the software pieces to be migrated;
- and
- a migration control unit configured to perform a control so that the software pieces are migrated to another server based on the migration order of the software pieces determined by the determination unit.
A migration method performed by a communication system, the method comprising:
- determining, based on software pieces through which a traffic flow passes, the software pieces running on a predetermined server;
- determining, based on an order of the software pieces through which the traffic flow passes, a migration order of the software pieces to be migrated;
- and
- performing a control so that the software pieces are migrated to another server based on the determined migration order of the software pieces to be migrated according to the determining.
