Abstract:
With an explosion of bandwidth on the Internet, it a natural to
rethink the focus for traffic management, congestion control and QoS
research. This talk will focus on that question and motivate the need
for new TM building blocks for the next generation internet. The aim
of these blocks is to deal with performance customization, scalability
issues and enable new economic models for provisioning/contracting
bandwidth in the Internet. Specifically, we will discuss a new
overlay feedback-based architecture to scale congestion control and
move bottlenecks to the edges of the network. With bottlenecks at the
edges, it becomes possible to do edge-based dynamic provisioning of
services and performance customization through
transport/application-aware buffer management schemes. With
congestion-information available at edges, new capabilities such as
dynamic contracting and congestion-pricing of such bandwidth services
are enabled. Bottlenecks at the edge also allow TCP-friendly
end-to-end services such as near zero-timeout and near zero-loss
services. This work is being implemented on a linux-based testbed with
50+ hosts and linux-routers.
Brief Biography:
Shivkumar Kalyanaraman is an Assistant Professor at the Department of
Electrical, Computer and Systems Engineering at Rensselaer Polytechnic
Institute in Troy, NY. He received a B.Tech degree from the Indian
Institute of Technology, Madras, India in July 1993, followed by
M.S. and and Ph.D. degrees in Computer and Information Sciences at the
Ohio State University in 1994 and 1997 respectively. His research
interests are in the area of computer networking, concentrated around
the theme of traffic management. He also works in the areas of automated
network management, multicast and multimedia networking. His special
interest lies in developing the interdisciplinary areas between traffic
and network management, control theory, economics, scalable simulation
technologies and video compression. He is a co-inventor in three patents
and has authored several papers, IETF drafts and ATM forum contributions.
He is an active consultant to several networking and telecom companies,
and a member of the technical advisory board of Packeteer Inc. He was
recently selected by MIT's Technology Review Magazine as one of the
TR100: 100 top innovators for the new millenium.
