Fundamentals of various social activities are “communities”, each of which is a group of people. In this research, by taking a novel sociological approach, we aimed at realization of “community-oriented network”, which enables natural mapping of social activities in communities onto communication networks. The primary objective of this research includes the design of network architecture for providing flexible and efficient communication infrastructure to communities and the establishment of fundamental technologies. We actively performed research regarding, in particular, three fundamental technologies (i.e., entity control, community control, and semantic communication) toward realization of community-oriented network. As entity control, theoretical research on mutual interference of Cloud lives migration and traffic engineering and their integratedcontrol were studied. As community control, we developed an estimation method of community’ s activity from a social network, which is a graphical representation of social interactions. As semantic communication, a content-centric network architecture which enalbes closed communication per community was designed.
