Research Projects

Summer’06-Fall’07

Developed a new transport protocol, Priority-Layered Transport (PLT), for long-haul networks. Spent two summers at Bell Labs, Lucent Technologies, New Jersey working on this problem. I hacked into the Linux TCP code to build this protocol. I implemented a performance-enhancing proxy and evaluated it on a wide-area testbed (Emulab). The work also involved building a simulation code for the protocol in NS (C We are currently working on a patent for this technology and intend to integrate with the UNIX kernel. (Collaborating with T. V. Lakshman, M. Kodialam,(Lucent Technologies, Holmdel) and P. Francis)

Summer’04-Spring’06

Designed Chunkyspread, a heterogeneity-aware end-to-end multicast protocol for live streaming applications. The protocol has been tested on Emulab, and will be shortly deployed on Planetlab. The system along with the simulator has been implemented in C++ (more than 25K lines of code). (Collaborated with P. Francis and K. Yoshida)

Our technology, Chunkyspread, got a mention in the ten emerging innovations in the March/April 2007 Issue of MIT Technology Review

Spring’04

Involved in a performance analysis of Willow, an overlay infrastructure implemented in Java. (Collaborated with R. V. Renesse )

Summer’02-Summer’03

Involved in developing real-time resource allocation algorithms for synchronous and asynchronous Ad Hoc wireless mesh networks at the Indian Institute of Technology Madras. This also involved wide-scale simulations in the GloMoSim simulator. (With Prof. C. S. R. Murthy )
