AKARI Sustainable Architecture Principles

2. Reality Connection• ID-Locator separation• Bi-directional authentication• Traceability

3. Sustainable Evolution• Self-* properties (emergent)• Autonomic distributed control• Scalable• Social Selection

1. KISS (Keep It Simple, Stupid)• Crystal synthesis (select, integrate, simplify)• Common layer (layer degeneracy)• End-to-end (original Internet)

CORE ConceptCORE Concept

Collaborative Overlay Research Environment Overlay test-bed based on “Private PlanetLab” Provision resources for mission critical services

Features we would like to have… Custom hardware to optimize overlay forwarding PoP/Core collocation (nodes “inside” network) Custom hardware to optimize overlay forwarding

Wireless/Sensors/Photonic capability in future Federation (e.g. PlanetLab, OneLab) Target overlay research Not just on distributed system apps More on network core architectures

Utilize both private & public environments Local v.s. Global / Provisioned v.s. Best-Effort

New Generation Perspectives to Overlay NetworkNew Generation Perspectives to Overlay Network

- Testbed for prototype and evaluate a new generation network design- Evolutional nature of overlay network to incorporate into the design
