Career Highlights:
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.

Research Areas:
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 video compression.

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.
