Abstract: An object of the present invention is to provide a video analysis system and a video analysis method in which ownership between a person and baggage can be comprehensively determined. In a system that analyzes videos photographed by plural cameras, a detection/tracking process is performed for first and second objects using videos of plural cameras, and a relationship degree between the first and second objects is determined on the basis of the types of the first and second objects and a distance between the objects to be stored in a database.

Abstract: A disclosed example is a network system including physical nodes. The network system provides a virtual network system including virtual nodes allocated computer resources of the physical nodes. In a case where the network system performs migration of a first virtual node for executing service using computer resources of a first physical node to a second physical node, the network system creates the communication paths for connecting the second physical node and the neighboring physical nodes on the physical links, starts the service executed by the first virtual node using the computer resources secured by the second physical node, switches communication paths to the created communication paths for switching the virtual links.
