Broad, open consortium executing research projects to achieve aggressive goal Roadmap organization establishing reference architectures and research targets to overcome major challenges facing network scaling and energy Venue for cooperation and enabling demonstrations among research organizations Forum for the exchange of information on energy trends, challenges, and research on communication networks 5

6. GreenTouch © 2010 GreenTouch Approach Bottom Up Research Organization Use of models to structure and guide research and collaboration Funding through member contributions & external sources Gauge impact of innovations on: Alternative metrics (carbon footprint, network power, embedded energy) Adjacent technologies (data centers, handsets) Measure, model and predict energy consumption in ICT networks (equipment trends, traffic, deployment) 6

7. GreenTouch © 2010 Consortium 5 Year Goal 7  Define architectures  Demonstrate tech. Use models for network in 2020 to set technology demonstration requirements

8. GreenTouch © 2010 12 targets achieved 1 target achieved Use Architecture Models & Targets to Track Progress Define architectures and track research results Identify targets for each architecture and update network efficiency in model as targets are achieved Working groups define targets and evaluate completion Targets can be achieved within GreenTouch projects or from broader community Identify gaps in effort and solicit new activities Goal 3 targets achieved Remaining targets achieved 8
