Although the flow and dissipation of energy has long been a topic of
interest with respect to communication networks, growing concerns over
global warming have brought renewed focus to this subject. Many
fundamental aspects are already understood. Of central importance is
the Shannon channel capacity, which provides a hard limit for the
minimum energy consumed in processing or transporting information with
fidelity in dissipative systems. Today, communication systems that make
up the internet consume energy at levels much higher than this
fundamental limit. Both wireless and optical transport, however, are
near or rapidly approaching their respective Shannon limits. In
general, power consumption in the internet is a complex mixture of
contributions from many different technologies. Recently we constructed
a transaction-based model of network energy consumption to help gain
insight into these issues. In this talk, I'll describe our model and
how it relates to energy use in the internet. We'll also review
concepts on limits to energy consumption and where those limits might
stand with respect to energy dissipation in networks today.
Bio:
*Daniel C. Kilper* received the B.S. degree in electrical engineering
and the B.S. degree in physics from Virginia Polytechnic Institute
& State University, Blacksburg, VA, USA, in 1990, and the M.S. and
Ph. D. degrees in physics from The University of Michigan, Ann Arbor,
MI, USA, in 1992 and 1996. Following his post-doctoral work at the
Optical Technology Center in Montana State University, he became an
assistant professor of physics at the University of North Carolina,
Charlotte, USA. In 2000, he joined the Advanced Photonics Research
Department as a member of technical staff at Bell Laboratories, Lucent
Technologies in Holmdel, NJ, USA. In 2007 he became a member of the
Bell Labs Optical Transmission Systems and Networks Research Department
in Alcatel-Lucent. Dr. Kilper is an associate editor for the OSA/IEEE
Journal of Optical Communications and Networking. He is a senior member
of IEEE and has served on the Member and Educational Services Council,
the OSA Leadership Award Committee, and the Esther B. Hoffman Award
Committee of the Optical Society of America. He is currently on the
technical program committee for CLEO/Europe and has served on
committees for CLEOIQEC, COIN/ACOFT, and OPTO/Southeast. From
2003-2006 he was a member of the Bell Labs Advisory Council on
Research. While at Bell Laboratories he has conducted research on
optical performance monitoring, transmission, architectures and control
systems for transparent and re-configurable optical networks. Dr.
Kilper has authored or co-authored more than 80 journal publications
and conference presentations, including one book chapter.
