I have moved from Calgary; I 'm now an Assistant Professor
at the Indian Institute of Technology, Delhi. You can find
my new web page here.
(updated July 2007)
I am an Assistant Professor in the Department of Computer Science
at the University of Calgary.
I am a member of the Distributed
I joined the University of Calgary in January 2004.
Research Interests and Activities
My general research interests are in the areas
of performance evaluation of distributed computer systems and computer
networks. Specific research interests include multimedia streaming systems,
Web performance, network architecture/protocols, network measurement/modeling,
and peer-to-peer systems.
The current focus is on the following topics:
- Traffic classification: Identification and classification
of network flows by application type, both at the network edge
and at the network core. This topic is spearheaded by graduate student
and is in collaboration with Martin Arlitt, Ira Cohen, and Carey Williamson.
(See our SIGCOMM MINENET'06 paper, SIGMETRICS'07 poster paper,
and WWW'07 paper)
- Media streaming: Design of next-generation content delivery protocols,
experimental evaluation of streaming in wired/wireless networks, and
rate control for streaming media. Graduate student
has been working on this topic. Former graduate student Sean Boyden also
worked on this topic. Collaborators include Zongpeng Li, Carey Williamson,
and Derek Eager.
(See our ACM MM '06, SPIE/ACM MMCN'07,
and IEEE IPCCC'07 papers)
- Workload characterization: Characterization of media, Web,
and Peer-to-Peer traffic.
Graduate students Naimul Basher
and Phillipa Sessini
are interested in different aspects of this broad research topic.
- TCP throughput models: Development and validation of throughput models
of TCP variants, and application of TCP throughput model to understand performance
of large, distributed applications. Graduate student
is the driving force behind this research. I collaborate with
Carey Williamson on this topic. (See our
IEEE ICC'06 paper)

I contribute to the computer systems performance evaluation and
computer networks communities by reviewing papers for journals and
conferences. My recent professional activities include:
Program committee membership in
(The 2004 International Conference on
Parallel and Distributed Processing Techniques and Applications).
Associate Editor for the Journal of Computer Science.
I am a member of ACM,
and ACM SIGCOMM.
