Business-As-Usual Trends

• Model network using state-of-art commercial technology

• Account for high and low traffic trends by service

• Switching, routing & WDM is small, but growth is unsustainable

• Traffic growth: >30%/year

• Equipment efficiency: 10%-20%/year

What is GreenTouch?

• 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

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)

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
