GreenTouch: 90% Reduction in Network Energy Consumption by 2020

The goal of a 90% reduction in network energy consumption by 2020 compared to a 2010 baseline is achievable, according to a new study published by the GreenTouch Consortium, a global research initiative dedicated to dramatically improving network energy efficiency.  This remarkable cut in electricity can be achieved while accounting for the dramatic increase in network traffic over this same decade.

GreenTouch said its study applied advanced modeling to better understand potential network operations in 2020 in comparison to those in 2010.

Key findings include:

  • Mobile networks stand to benefit the most from energy efficiency efforts, as they are the most inefficient and yet the fastest growing networks in terms of data volumes.
  • Mobile networks could realize potential energy efficiency improvements of up to 1043 times.
  • Energy efficiencies in fixed-line and core networks are also expected, but will be less dramatic. The modeling shows potential improvements in fixed access networks of 449 times and improvements in the core network of 95 times. Core networks are already relatively energy-efficient, so further gains will be less significant and much harder to achieve than with mobile networks.

Some of the key technologies that could deliver the biggest efficiency gains include:

  • Infrastructure sharing by mobile network operators.
  • Small cell deployments in cities.  Less energy is needed to transmit data over shorter distances.
  • Discontinuous transmission during periods without traffic.
  • Bit interleaved passive optical networking (Bi-PON), a new protocol that would use TDM to more efficiently move packets to their intended destination.
  • Dynamic allocation of resources in the network core to diurnal traffic fluctuations.
  • Power models for energy efficient hardware and network equipment.  Gains from Moore's Law.

Additional technologies that could add even further gains beyond those calculated by this study include the separation of the control plane from the data plane, and further optimization of Content Delivery Networks (CDNs).

“We are extremely proud of the progress we’ve made in our first three years, yet there is still much more we can do to improve efficiencies and effectively reinvent technologies in the name of environmental stewardship,” said Thierry Van Landegem, chairman, GreenTouch. “Reducing energy by 90 percent is conservative as we have many projects underway whose effects were not taken into account in that number.”

The GreenTouch Consortium, which was founded in 2010, has grown to include a wide range of participants, spanning the research community, academia, global service providers and networking equipment vendors.

GlobeNet and Equinix Optimize Brazil-US Connectivity

GlobeNet, a wholly owned subsidiary of Oi (formerly Brasil Telecom), has extended its low latency network into Equinix’s MI3 International Business Exchange (IBX) data center in Boca Raton, Florida, opening up the fastest IP traffic route from the United States to Brazil.

Equinix’s MI3 facility serves as a carrier-neutral network access point for GlobeNet to connect its low latency, subsea cable route from Equinix’s SP2 facility in São Paulo, Brazil.

Equinix said undersea cables are typically terminated at a landing station.  The new arrangement with GlobeNet brings its undersea fiber connectivity directly into the Equinix data center in Boca Raton.
The companies noted that roughly 75 percent of all network traffic emanating from Latin America enters the United States via Miami. Globally, MI3 has the sixth highest Internet capacity and is a key hub location for domestic and international traffic routes. As a result, Equinix and its Brazilian subsidiary ALOG are perfectly positioned to serve high-bandwidth events, such as the upcoming 2014 FIFA World Cup and 2016 Summer Olympics in Brazil.

"Fueled by the convergence of telecommunications infrastructures, MI3 is becoming a popular connectivity hub for global carriers, Internet service providers and other Internet-related businesses and organizations. We are thrilled to have GlobeNet expand into MI3, opening up a new bilateral submarine connectivity opportunity for major network providers," stated Jim Poole, general manager, Global Networks & Mobility at Equinix.

Samsung Tests Adaptive Array Transceiver for Gigabit Speed Cellular

Samsung Electronics is testing adaptive array transceiver technology operating in the millimeter-wave Ka band at a frequency of 28 GHz at a speed of up to 1.056 Gbps to a distance of up to 2 kilometers.  The company said the technology will be the core of future 5G networks.

The new technology sits at the core of 5G mobile communications system and will provide data transmission up to several hundred times faster than current 4G networks.

Samsung's adaptive array transceiver test combines 64 antenna elements, enabling the system to overcome the radio propagation loss at millimeter-wave bands, much higher than the conventional frequency bands ranging from several hundred MHz to several GHz.
Samsung said plans to accelerate the research and development of 5G mobile communications technologies, including adaptive array transceiver at the millimeter-wave bands, to commercialize those technologies by 2020.

OIF Begins Work on SDN Framework

The Optical Internetworking Forum has started work on an SDN Framework document to better focus the conflicting and confusing requirements that vary in the industry for Transport SDN.

"The OIF is working on defining a framework for the industry to clarify the interfaces required in the Transport SDN ecosystem, leveraging input from carriers,” said Jonathan Sadler, Tellabs and the OIF’s Technical Committee chair. “In addition, the OIF is advancing work in 100G interconnect and has completed implementation agreements that focus on technology from past interoperability demonstrations.  The Forum continues to drive technology efforts that are necessary for providing higher speeds and lower costs for the industry."

The OIF is also working on plans for an SDN networking interoperability demonstration for 2014 and will showcase technology outlined in the SDN Framework document.

Some other highlights from the OIF's recent quarterly meeting:

At the Physical and Link Layer (PLL), the OIF is undertaking two projects addressing Thermal Interface requirements and CFP2 Coherent Optics Transceiver module. The first project will specify a module-type agnostic thermal interface between anoptical module and a host bringing consistency and standardization to the industry.  A second new project focuses on a Coherent Optics Transceiver module in a CFP2 form factor and will help maximize faceplate density and minimize first install costs on metro/regional line-side transport or switching platforms.

OIF members completed and approved the Next Generation Interconnect Framework white paper as well as implementation agreements on Multilink Gearbox and a Multilayer Amendment for E-NNI. The Multi-link Gearbox 2.0 implementation agreement defines a 4x25G lane configuration comprised of 20 MLG lanes and an 8x25G lane configuration comprised of 40 MLG lanes.  Both are configured to carry multiple 10GBASE-R signals or a single 40GBASE-R signal.  This IA will serve as an important infrastructure element in high rate systems.

A second IA, the Multilayer Amendment defines generic signaling and routing extensions to the OIF’s E-NNI 2.0 implementation agreement in support of multilayer networks.  Based on technology demonstrated in past interoperability tests the Multilayer Amendment provides the ability for the control plane to determine the lowest cost way to deliver a service using different technologies.
