Outline of Final Research Achievements

As environments surrounding the Internet become more changeable, a design approach that requires less equipment to scale up networks against the traffic growth under various environmental changes is needed. Here, we propose an evolvable network design approach where network equipment is deployed without predetermined purpose rather than for a preplanned purpose. We use mutual information on node degree to measure the topological diversity of networks, and maximize topological diversity in the network design by minimizing the mutual information. Evaluations show that, compared to networks with ad-hoc design method, networks constructed by our design approach can efficiently uses the network equipment among various environments.
