GreenTouch Video Library

GreenTouch has delivered a comprehensive portfolio of technologies, architectures, algorithms and protocols for dramatically improving network energy efficiency. In this video library you will find a video introducing GreenTouch, a video where the final results are shared, and multiple videos on specific technologies and architectures.

GreenTouch Overview

About the GreenTouch Consortium

GreenTouch is a consortium of leading Information and Communications Technology (ICT) industry, academic and non-governmental research experts dedicated to fundamentally transforming communications and data networks, including the Internet, and significantly reducing the carbon footprint of ICT devices, platforms and networks.

Final Results of GreenTouch

GreenTouch has demonstrated that the net energy consumption in an end-to-end network can be reduced by 98% compared to 2010 while supporting a dramatic traffic increase from 2010 to 2020.

Mobile Access

Mobile Access Networks

A methodology was developed to evaluate the energy efficiency of large-scale wireless networks and used to benchmark all proposed architectures and technologies that enable the radio access network to provide full coverage and the capacity and performance required in 2020. The final mobile architecture is created by selecting the most energy-efficient technologies for each deployment area, such as city centers or rural areas.

Power Model for Today’s and Future Base Stations

An advanced power model and online tool was developed that provides a fundamental understanding and a realistic evolution of the power consumption and hardware capabilities for a diversity of wireless base station types and operating conditions.

Beyond Cellular Green Generation (BCG2)

The BCG2 project goes beyond the traditional network architecture by using small cells, and by completely separating the signaling and data functions at the wireless interface allowing for intelligent on-off management of the small cells.

Fixed Access

Bit-Interleaving Passive Optical Networks

GreenTouch introduces a new technology that will dramatically reduce energy consumption in fiber-to-the-home (FTTH) networks, as well as other applications. The breakthrough Bit-Interleaved Passive Optical Network (Bi-PON) technology is the second major milestone reached by the consortium. When deployed, it will enable a power reduction of 30 times over current technologies while improving performance and reducing cost.

GreenTouch Announces Two New Technologies for Fixed Access Networks

GreenTouch announces the development of two new technologies - the Virtual Home Gateway and Point-to-Point Optical Transceiver - that will reduce overall energy consumption in wireline access networks by an impressive 46 percent, which translates into a combined energy savings equivalent to the annual greenhouse gas emissions of 1.2 million passenger vehicles.

Virtual Home Gateway

The GreenTouch Virtual Home Gateway project replaces residential in-home gateways—devices used to access dedicated services such as data, voice and TV—with servers in the cloud. Hundreds of thousands of in-home boxes could be replaced by a smaller number of servers. This approach is expected to reduce power consumption in the residential access network by 19 percent, equivalent to the annual electricity consumption of 833,000 typical households

Point-to-Point Optical Transceiver

Core Networks

Energy Efficient Content Distribution in Core Networks

A new analytic optimization framework to minimize the power consumption of content distribution networks was introduced leading to more distributed clouds and data centers located closers to the end users. Algorithms are developed for the number and placement of the clouds and the distribution of the content objects.

Universal Router Energy Model

This video highlights a new and universal power model to understand the power consumption and evolution of core network routers and the impact on the energy consumption of Internet services.
