High speed broadband will create energy bottleneck and slow Internet
November 25, 2008"Increased services like Video on Demand will put pressure on the system and create an energy bottleneck," said Dr Kerry Hinton of the University's Department of Electrical and Electronic Engineering and the ARC Special Centre for Ultra-Broadband Information Networks (CUBIN).
In a world-first model of internet power consumption, University of Melbourne researchers have been able to identify the major contributors to Internet power consumption as the take-up of broadband services grows in the coming years.
"It has now become clear that the exponential growth of the Internet is not sustainable, "said Dr Hinton.
The result indicates that, even with the improvements in energy efficiency of electronics, the power consumption of the Internet will increase from 0.5% of today's national electricity consumption to 1% by around 2020.
Dr Hinton says the growth of the Internet, IT broadband telecommunications will provide a wide range of new products and services.
New home services include Video on Demand, web based real-time gaming, social networking, peer-to-peer networking and more. For the business community, new services may include video conferencing, outsourcing and tele-working.
"To support these new high-bandwidth services, the capacity of the Internet will need to be significantly increased. If Internet capacity is increased, the energy consumption, and consequently the carbon footprint of the Internet will also increase."
"This will place a major burden on the nation's power infrastructure as well as significantly contribute to green house gas production." Hinton says major ICT and Internet based companies are already experiencing difficulties due to the size and power requirements of servers, routers and data centres.
The model includes the entire network infrastructure required to provide the increasing traffic volumes arising from proposed new high-bandwidth services.
"Increasing amounts of energy will be needed to power and cool Internet equipment that provides high speed broadband."
"If service providers don't update their equipment, energy consumption will soar, but then cost of updating may also be prohibitive."
"This model is important because it shows us where we must focus our efforts to ensure the Internet is energy efficient. If we don't do this, the Internet will not fulfil the social and economic promise many of us are expecting of it," Dr Hinton said
The research will be presented at "Symposium on Sustainability of the Internet and ICT" hosted by The ARC Special Centre for Ultra-Broadband Information Networks (CUBIN) 25 - 26 November at the University of Melbourne.

James Webb Space Telescope Begins to Take Shape at Goddard
NASA's James Webb Space Telescope is starting to come together. A major component of the telescope, the Integrated Science Instrument Module structure, recently arrived at NASA Goddard Space Flight Center in Greenbelt, Md. for testing in the Spacecraft Systems Development and Integration Facility.
A new cloaking method
University of Utah mathematicians developed a new cloaking method, and it's unlikely to lead to invisibility cloaks like those used by Harry Potter or Romulan spaceships in "Star Trek." Instead, the new method someday might shield submarines from sonar, planes from radar, buildings from earthquakes, and oil rigs and coastal structures from tsunamis.
Artificial noise saves energy
Against the background of climate change, how can xDSL systems function more energy-efficiently and cost-effectively? Scientists are providing a solution combining existing methods which network providers could implement immediately.
Manatees can probably hear which directions boats approach from

Drawing inspiration from nature to build a better radio
MIT engineers have built a fast, ultra-broadband, low-power radio chip, modeled on the human inner ear, that could enable wireless devices capable of receiving cell phone, Internet, radio and television signals.
New 'broadband' cloaking technology simple to manufacture
Researchers have created a new type of invisibility cloak that is simpler than previous designs and works for all colors of the visible spectrum, making it possible to cloak larger objects than before and possibly leading to practical applications in "transformation optics."
Scientists cable seafloor seismometer into state earthquake network
A newly laid, 32-mile underwater cable finally links the state's only seafloor seismic station with the University of California, Berkeley's seismic network, merging real-time data from west of the San Andreas fault with data from 31 other land stations sprinkled around Northern and Central California.
Spreading high-speed Internet to rural areas
To cut the cost of bringing high-speed Internet to rural areas, Dr. Ka Lun Lee and colleagues at the University of Melbourne and NEC Australia in the state of Victoria are experimenting with a way to boost the reach of existing technology.
