RESEARCH
INTERESTS

TCP Congestion Control, DiffServ, Large Bandwidth Delay

RESEARCH
PLAN

I have been working on the modeling and analysis of TCP congestion control. Preliminary results are obtained about per-flow queue build-up, per-flow queue service rate, and queueing delay using deterministic fluid-flow rate-based model. The results will be applied to DiffServ. Draft papers will be available shortly. I hope to work on this topic or related matters during my visit to UIUC.
