Resume/CV Latest stuff Reed-Solomon codec Recently I wrote this Reed-Solomon codec. A small test program to run it is also available. Research Areas • Data dissemination • Distributed systems and algorithms • Coding and Information Theory Current Work Storage: My work on storage focuses on the use of erasure codes in fault-tolerant distributed storage. More information on my work in this area can be found in my list of publications and preprints. Data dissemination: I have worked on schemes for

My master's thesis describes the design and implementation of a scalable video-on-demand scheme over the Internet. This technique, which we call Fuzzycast , uses efficient network supported broadcast mechanisms (e.g., IP multicast) to simultaneously satisfy multiple requests for the same data. Fuzzycast relies on a patented periodic broadcast mechanism and uses the least server bandwidth of all known periodic broadcast video-on-demand schemes, while also being very simple to build and deploy.
