Since joining Rensselaer in 1997, Kalyanaraman has taught in the
university's information technology and computer science departments,
in addition to his role in ECSE. He has earned several prestigious
recognitions, such as being named one of the Massachusetts Institute
of Technology Technology Review magazine's top 100 young
innovators for the next millennium. Rensselaer honored Kalyanaraman
with a School of Engineering Research Award in 2003 and the Faculty
Early Career Award in 2001 a recognition conferred once a
year upon a very select subset of young faculty with three to ten
years of service. He was named an honored member of International
Who's Who of Information Technology in 1999; and as a student at
the Indian Institute of Technology, he was given the Technical Merit
Award, for placing third out of nearly 100,000 students.
Kalyanaraman has published two book chapters and
has had over a dozen refereed articles published or accepted. He
and his team members have filed or been granted eight patents, and
he has given more than 40 invited talks in the last three years
at such prominent institutions as the Massachusetts Institute of
Technology, Carnegie-Mellon University, the University of California
at Berkeley, Columbia University, AT&T Research Labs, Motorola
Labs, and Intel Architecture Labs. He also is the co-founder of
Premonitia, Inc., a network management company.
Kalyanaraman's research interests include computer networking, with
a concentration on traffic management. His studies include topics
of congestion control architectures, Quality of Service (QoS), high-speed
wireless last-mile networks, free-space optical networks, network
management, multicast, pricing, multimedia networking, and performance
analysis. He is also keenly interested in developing the interdisciplinary
areas between traffic management, wireless communication, optoelectronics,
control theory, economics, scalable simulation technologies, and
His doctoral work on rate-based congestion control
algorithms for traffic management in ATM networks has led to numerous
contributions to the ATM Forum, a standards body. Notable articles
from this work included a widely cited Institute of Electrical and
Electronics Engineers (IEEE)/Association for Computing Machines
(ACM) Transactions of Networking paper on the "ERICA"
switch algorithm and in the Performance Evaluation Journal
on the OSU scheme for congestion control in ATM networks. This work
considerably influenced the standards process and is included in
the final ATM Forum traffic management standards.
Combined funding for Kalyanaraman's research totals
over $4 million and comes from such sources as the National Science
Foundation, the Defense Advanced Research Projects Agency (DARPA),
Intel, AT&T Research, IBM, and the Army Research Office (ARO).
He works actively with standards bodies including the ATM Forum
and the Internet Engineering Task Force (IETF) to produce open-source
Linux-based research distributions.
Current projects include Congestion Control Schemes
and Architectures, Control-theoretic Foundations of Congestion Control,
Multicast Congestion Control, Dynamic Differentiated Services and
Internet Pricing, TCP Performance and Better "Best-Effort"
Service, and On-line Simulation for Network Management and Control.
Kalyanaraman also leads an Internet2 committee
that is drafting the architecture for a general overlay network
facility for use by networking researchers.
