AKARI’s Current Focus: Network Architecture Role Safety & Security No vertical division. Common infrastructure Enjoy fundamental technology advances Ubiquity Energy-Saving Diversity Future requirements from diverse users and society Process Design Principles Network Architecture Select, integrate and simplify Evolving, future fundamental technologies proof Feedback -ofconcept Testbed (Overlay Network) All Optical Software Radio Theoretical Limits NETWORK SCIENCE Flexible to adopt a new user requirement Capacity (Peta) - Optimal Integration of many components - Stable enough to rely on for a long time - Grand-Designing a New Generation Network beyond 2015 (C) National Institute of Information and Communications Technology 4

AKARI Sustainable Architecture Principles Capacity for Quality 1. KISS (Keep It Simple, Stupid) • Crystal synthesis (select, integrate, simplify) • Common layer (layer degeneracy) • End-to-end (original Internet) 2. Reality Connection • ID-Locator separation • Bi-directional authentication • Traceability Reliable Network Space 3. Sustainable Evolution • • Self-* properties (emergent) Autonomic distributed control Scalable Social Selection For Future Diverse Society (C) National Institute of Information and Communications Technology 5
