Abstract (in Japanese) (See Japanese page) 
(in English) Current map services aim at the upgrade by means of combining the computer graphics and the still images, such as aerial photos and street-view photos. However, they have a significant problem, miss match with a present situation, because they utilize still pictures. In this paper, we consider a new map service which makes use of real-time video filmed with a variety of cameras and the computer graphics to resolve the problem current map services. To realize this map service, it is necessary to deal with huge quantities of video stream transmission and rendering of real-time video and the computer graphics, and the load balancing control is needed for scalability. A lot of changing factors in this service, i.e., density of cameras and the number of users, make it difficult to achieve the efficient use of the physical resource such as network resources and the processing resources for load balancing. Therefore, we propose a virtual network layer which is an interlayer between the physical resource and the service demand and simplifies the optimization problem in the load-balancing control.
