  5. 5. Ideal Efficiency Improvements on BAU: Flat in 2020 Improving network efficiency at best keeps power consumption flat over next decade What happens after 2020? Can only use ‘sleep modes’ once 100 BAU Current technology will onlyPower/User (W) sustain us for another decade: how do we go beyond? 10 Optimistic Improvements 1 2008 2010 2012 2014 2016 2018 2020 Year
  6. 6. ICT Industry Responds First Step: metrics, awareness, standards, call to action Global e-Sustainability Initiative (GeSI) ITU-T GreenGrid Semiconductor Industry Already Organized for the Long View: Next Step: cooperation, action ITRS 15 years out EARTH: LTE 2x Mobile VCE: Green Radio 100x Institute for Energy Efficiency: Wireless and optical 100x GreenTouch: ICT Networks 1000x6 GreenTouch : Building the Roadmap | 2011 © 2011 GreenTouch Consortium
  7. 7. What is GreenTouch? GreenTouch Mission By 2015, our goal is to deliver the architecture, specifications and roadmap — and demonstrate key components — needed to increase network energy efficiency by a factor of 1000 from current levels. Broad, open and global 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, & research on communication networks7 GreenTouch : Building the Roadmap | 2011 © 2011 GreenTouch Consortium

Some Research Projects… Beyond Cellular – Green Mobile Networks Virtual Home Gateway Optimal End-to-End Resource Allocation Service Energy Aware Optical Networks Steady Green Transmission Technologies flow of new Minimum Energy Access Architectures Projects Single-Chip Linecards & coop. Large-Scale Antenna Systems activities Highly-Adaptive Layer Mesh Networks Massive MIMO10 GreenTouch : Building the Roadmap | 2011 © 2011 GreenTouch Consortium
  11. 11. New Approaches: Focus on Energy New devices • Analog vs digital, best use of optics and electronics • Old ideas finding new life: large scale MIMO New architectures • trade-off transmission/bandwidth and processing, distributed versus centralized New protocols • Longer packet sizes or no packets at all for certain applications Service optimized networks • Move away from one size fits all—use most energy efficiency hardware for the service • Coordinate service delivery/applications with network hardware operation Restructuring layers, architectures, feature options • How much do way pay in energy for convenience? duplicated functions (FEC)? • What technologies do we really need in order to support the essential capabilities?11 GreenTouch : Building the Roadmap | 2011 © 2011 GreenTouch Consortium
  12. 12. Minimizing Processing Repetition • Unnecessary router hops • Inter-operator exchange Separate what is • Multiple transmissions needed from what Remove processing from the data path is convenience • Separate control channel? Focus on Service • Content delivery vs. browsing vs messaging Push to the edges • FEC • Security, policy processing Simplified Addressing • Geographic addressing/binary switching12 GreenTouch : Building the Roadmap | 2011 © 2011 GreenTouch Consortium
