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.

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.
