The Internet's huge success has become its greatest weakness. Millions of people use the Internet every day to read the news, shop, and do research. This wide deployment and commercial success has led to a world in which fundamental changes to Internet protocols are difficult to deploy.
John Jannotti is interested in how overlay networks and peer-to-peer systems fight this trend by allowing innovation without consensus, the construction of virtual networks built among cooperating computers, and how innovative protocols can be deployed in these spaces. He is also interested in the challenges of efficiency, fairness, and scalability, which temper the freedom to innovate in this context.
Besides widely distributed systems, Prof. Jannotti's interests include wireless protocols, operating system flexibility, and sensor networks.
